Dan Fandrich (5 Dec 2023) - github/labeler: switch from the beta to labeler v5 Some keys were renamed and the dot option was made default. Closes #12458 Daniel Stenberg (5 Dec 2023) - DEPRECATE: remove NTLM_WB in June 2024 Ref: https://curl.se/mail/lib-2023-12/0010.html Closes #12451 Jacob Hoffman-Andrews (4 Dec 2023) - rustls: implement connect_blocking Closes #11647 Daniel Stenberg (4 Dec 2023) - examples/rtsp-options.c: add Just a bare bones RTSP example using CURLOPT_RTSP_SESSION_ID and CURLOPT_RTSP_REQUEST set to CURL_RTSPREQ_OPTIONS. Closes #12452 Stefan Eissing (4 Dec 2023) - ngtcp2: ignore errors on unknown streams - expecially in is_alive checks on connections, we might see incoming packets on streams already forgotten and closed, leading to errors reported by nghttp3. Ignore those. Closes #12449 Daniel Stenberg (4 Dec 2023) - docs: make all examples in all libcurl man pages compile Closes #12448 - checksrc.pl: support #line instructions makes it identify the correct source file and line - GHA/man-examples: verify libcurl man page examples - verify-examples.pl: verify that all man page examples compile clean - RELEASE-NOTES: synced Graham Campbell (2 Dec 2023) - http3: bump ngtcp2 and nghttp3 versions nghttp3 v1.1.0 ngtcp2 v1.1.0 In docs and CI Closes #12446 - CI/quiche: use `3.1.4+quic` consistently in CI workflows Closes #12447 Viktor Szakats (2 Dec 2023) - test1545: disable deprecation warnings Fixes: https://ci.appveyor.com/project/curlorg/curl/builds/48631551/job/bhx74e0i66yr p6pk#L1205 Same with details: https://ci.appveyor.com/project/curlorg/curl/builds/48662893/job/ol8a78q9gmil b6wt#L1263 ``` tests/libtest/lib1545.c:38:3: error: 'curl_formadd' is deprecated: since 7.56 .0.

Prior to this change if some protocols were disabled but not digest auth then a build error would occur due to missing base64 functions. Fixes https://github.com/curl/curl/issues/12440 Closes https://github.com/curl/curl/pull/12442 MichaÅ‚ Antoniak (1 Dec 2023) - connect: reduce number of transportation providers Use only the ones necessary - the ones that are built-in. Saves a few bytes in the resulting code. Closes #12438 David Benjamin (1 Dec 2023) - vtls: consistently use typedef names for OpenSSL structs The foo_st names don't appear in OpenSSL public API documentation. The FOO typedefs are more common. This header was already referencing SSL_CTX via . There is a comment about avoiding , but OpenSSL actually declares all the typedefs in , which is already included by (and every other OpenSSL header), so just use that. Though I've included it just to be explicit. (I'm also fairly sure including already triggers the Schannel conflicts anyway. The comment was probably just out of date.) Closes #12439 Lau (1 Dec 2023) - libcurl-security.3: fix typo Fixed minimal typo. Closes #12437 Stefan Eissing (1 Dec 2023) - ngtcp2: fix races in stream handling - fix cases where ngtcp2 invokes callbacks on streams that nghttp3 has already forgotten. Ignore the NGHTTP3_ERR_STREAM_NOT_FOUND in these cases as it is normal behaviour. Closes #12435 Emanuele Torre (1 Dec 2023) - tool_writeout_json: fix JSON encoding of non-ascii bytes char variables if unspecified can be either signed or unsigned depending on the platform according to the C standard; in most platforms, they are signed. This meant that the *i<32 waas always true for bytes with the top bit set. So they were always getting encoded as \uXXXX, and then since they were also signed negative, they were getting extended with 1s causing '\xe2' to be expanded to \uffffffe2, for example: $ curl --variable 'v=â€œ' --expand-write-out '{{v:json}}\n' file:///dev/nul l \uffffffe2\uffffff80\uffffff9c I fixed this bug by making the code use explicitly unsigned char* variables instead of char* variables. Test 268 verifies Reported-by: iconoclasthero Closes #12434 Stefan Eissing (1 Dec 2023) - cf-socket: TCP trace output local address used in connect Closes #12427 Jay Satiro (1 Dec 2023) - CURLINFO_PRETRANSFER_TIME_T.3: fix time explanation - Change CURLINFO_PRETRANSFER_TIME_T explanation to say that it includes protocol-specific instructions that trigger a transfer. Prior to this change it explicitly said that it did not include those instructions in the time, but that is incorrect. The change is a copy of the fixed explanation already in CURLINFO_PRETRANSFER_TIME, fixed by ec8dcd7b. Reported-by: eeverettrbx@users.noreply.github.com Fixes https://github.com/curl/curl/issues/12431 Closes https://github.com/curl/curl/pull/12432 Daniel Stenberg (30 Nov 2023) - multi: during ratelimit multi_getsock should return no sockets ... as there is nothing to wait for then, it just waits. Otherwise, this causes much more CPU work and updates than necessary during ratelimit periods. Ref: https://curl.se/mail/lib-2023-11/0056.html Closes #12430 Dmitry Karpov (30 Nov 2023) - transfer: abort pause send when connection is marked for closing This handles cases of some bi-directional "upgrade" scenarios (i.e. WebSockets) where sending is paused until some "upgrade" handshake is completed, but server rejects the handshake and closes the connection. Closes #12428 Daniel Stenberg (28 Nov 2023) - RELEASE-NOTES: synced - openssl: when a session-ID is reused, skip OCSP stapling Fixes #12399 Reported-by: Alexey Larikov Closes #12418 - test1545: test doing curl_formadd twice with missing file Reproduces #12410 Verifies the fix Closes #12421 - Curl_http_body: cleanup properly when Curl_getformdata errors Reported-by: yushicheng7788 on github Based-on-work-by: yushicheng7788 on github Fixes #12410 Closes #12421 - test1477: verify that libcurl-errors.3 and public headers are synced The script errorcodes.pl extracts all error codes from all headers and checks that they are all documented, then checks that all documented error codes are also specified in a header file. Closes #12424 - libcurl-errors.3: sync with current public headers Closes #12424 Stefan Eissing (28 Nov 2023) - test459: fix for parallel runs - change warniing message to work better with varying filename length. - adapt test output check to new formatting Follow-up to 97ccc4479f77ba3191c6 Closes #12423 Daniel Stenberg (27 Nov 2023) - tool_cb_prg: make the carriage return fit for wide progress bars When the progress bar was made max width (256 columns), the fly() function attempted to generate its output buffer too long so that the trailing carriage return would not fit and then the output would show wrongly. The fly function is called when the expected total transfer is unknown, which could be one or more progress calls before the actual progress meter get shown when the expected transfer size is provided. This new take also replaces the msnprintf() call with a much simpler memset() for speed.

Reviewed-by: Dan Fandrich Reviewed-by: Jay Satiro Closes #12378 - windows: use built-in `_WIN32` macro to detect Windows Windows compilers define `_WIN32` automatically. Windows SDK headers or build env defines `WIN32`, or we have to take care of it. The agreement seems to be that `_WIN32` is the preferred practice here. Make the source code rely on that to detect we're building for Windows. Public `curl.h` was using `WIN32`, `__WIN32__` and `CURL_WIN32` for Windows detection, next to the official `_WIN32`. After this patch it only uses `_WIN32` for this. Also, make it stop defining `CURL_WIN32`. There is a slight chance these break compatibility with Windows compilers that fail to define `_WIN32`. I'm not aware of any obsolete or modern compiler affected, but in case there is one, one possible solution is to define this macro manually. grepping for `WIN32` remains useful to discover Windows-specific code. Also: - extend `checksrc` to ensure we're not using `WIN32` anymore. - apply minor formatting here and there. - delete unnecessary checks for `!MSDOS` when `_WIN32` is present.

However, building the clientconn requires resending the HTTP/2 connection preface, which is incorrect from a protocol perspective. That in turn causes servers to send GOAWAY frames, effectively degrading performance to "no connection reuse" in the best case. It may also be triggering some bugs where requests get dropped entirely and reconnects take too long. This doesn't rule out HTTP/2 support with Hyper, but it may take a redesign of the Hyper integration in order to make things work.

This works fine because the set of schemes is known and cannot change in a build. The hash algorithm and table size is made to only make a single scheme index per table entry. The perfect hash is generated by a separate tool (scripts/schemetable.c) Closes #12347 - scripts: add schemetable.c This tool generates a scheme-matching table. It iterates over a number of different initial and shift values in order to find the hash algorithm that needs the smallest possible table.

Reviewed-by: Daniel Stenberg Reviewed-by: Marcel Raad Closes #12324 Daniel Stenberg (15 Nov 2023) - urldata: move cookielist from UserDefined to UrlState 1. Because the value is not strictly set with a setopt option. 2. Because otherwise when duping a handle when all the set.* fields are first copied and an error happens (think out of memory mid-function), the function would easily free the list *before* it was deep-copied, which could lead to a double-free. Closes #12323 Viktor Szakats (14 Nov 2023) - autotools: avoid passing `LDFLAGS` twice to libcurl autotools passes `LDFLAGS` automatically linker commands. curl's `lib/Makefile.am` customizes libcurl linker flags. In that customization, it added `LDFLAGS` to the custom flags. This resulted in passing `LDFLAGS` _twice_ to the `libtool` command. Most of the time this is benign, but some `LDFLAGS` options can break the build when passed twice. One such example is passing `.o` files, e.g. `crt*.o` files necessary when customizing the C runtime, e.g. for MUSL builds. Passing them twice resulted in duplicate symbol errors: ``` libtool: link: clang-15 --target=aarch64-unknown-linux-musl [...] /usr/lib/a arch64-linux-musl/crt1.o [...] /usr/lib/aarch64-linux-musl/crt1.o [...] ld.lld-15: error: duplicate symbol: _start >>> defined at crt1.c >>> /usr/lib/aarch64-linux-musl/crt1.o:(.text+0x0) >>> defined at crt1.c >>> /usr/lib/aarch64-linux-musl/crt1.o:(.text+0x0) [...] clang: error: linker command failed with exit code 1 (use -v to see invocatio n) ``` This behaviour came with commit 1a593191c2769a47b8c3e4d9715ec9f6dddf5e36 (2013-07-23) as a fix for bug https://curl.haxx.se/bug/view.cgi?id=1217. The patch was a works-for-me hack that ended up merged in curl: https://sourceforge.net/p/curl/bugs/1217/#06ef With the root cause remaining unclear. Perhaps the SUNPro 12 linker was sensitive to `-L` `-l` order, requiring `-L` first? This would be unusual and suggests a bug in either the linker or in `libtool`. The curl build does pass the list of detected libs via its own `LIBCURL_LIBS` variable, which ends up before `LDFLAGS` on the `libtool` command line, but it's the job of `libtool` to ensure that even a peculiar linker gets the options in the expected order. Also because autotools passes `LDFLAGS` last, making it hardly possible to pass anything after it. Perhaps in the 10 years since this issue, this already got a fix upstream. This patch deletes `LDFLAGS` from our customized libcurl options, leaving a single copy of them as passed by autotools automatically. Reverts 1a593191c2769a47b8c3e4d9715ec9f6dddf5e36 Closes #12310 - autotools: accept linker flags via `CURL_LDFLAGS_{LIB,BIN}` To allow passing `LDFLAGS` specific to libcurl (`CURL_LDFLAGS_LIB`) and curl tool (`CURL_LDFLAGS_BIN`). This makes it possible to build libcurl and curl with a single invocation with lib- and tool-specific custom linker flags. Such flag can be enabling `.map` files, a `.def` file for libcurl DLL, controlling static/shared, incl. requesting a static curl tool (with `-static-libtool-libs`) while building both shared and static libcurl. curl-for-win uses the above and some more. These options are already supported in `Makefile.mk`. CMake has built-in variables for this. Closes #12312 Jay Satiro (14 Nov 2023) - tool_cb_hdr: add an additional parsing check - Don't dereference the past-the-end element when parsing the server's Content-disposition header. As 'p' is advanced it can point to the past-the-end element and prior to this change 'p' could be dereferenced in that case. Technically the past-the-end element is not out of bounds because dynbuf (which manages the header line) automatically adds a null terminator to every buffer and that is not included in the buffer length passed to the header callback.

This patch changes the single use of `stdint.h` guarded by `HAVE_STDINT_H` to use `stdint.h` unconditionally.

One dependency, LibreSSL, happens to publish an `arc4random` function (via its shared lib before v3.7, also via static lib as of v3.8.2). When trying to use this function in `lib/rand.c`, its protoype is missing. To fix that, curl included a prototype, but that used a C99 type without including `stdint.h`, causing: ``` ../../lib/rand.c:37:1: error: unknown type name 'uint32_t' 37 | uint32_t arc4random(void); | ^ 1 error generated. ``` This patch improves this by dropping the local prototype and instead limiting `arc4random` use for non-OpenSSL builds. OpenSSL builds provide their own random source anyway. The better fix would be to teach autotools to not link dependency libs while detecting `arc4random`.

On Windows this is highly unlikely and should be considered a bad build configuration. Such a bad configuration has already given us a bug that was hard to diagnose. See #12134 and #12136 for discussion. Ref: https://github.com/curl/curl/issues/12134 Ref: https://github.com/curl/curl/pull/12136 Closes https://github.com/curl/curl/pull/12221 Nico Rieck (29 Oct 2023) - openssl: make CURLSSLOPT_NATIVE_CA import Windows intermediate CAs - If CURLSSLOPT_NATIVE_CA on Windows then import from intermediate CA "CA" store after importing from root CA "ROOT" store. This change allows curl to work in situations where a server does not send all intermediate certs and they are present in the "CA" store (the store with intermediate CAs). This is already allowed by the Schannel backend. Also this change makes partial chain verification possible for those certs since we allow partial chain verification by default for OpenSSL (unless CURLSSLOPT_NO_PARTIALCHAIN). This is not allowed by the Schannel backend. Prior to this change CURLSSLOPT_NATIVE_CA only imported "ROOT" certs.

Turns out `_mingw.h` had the side-effect of setting a default `_WIN32_WINNT` value expected by `lib/config-win32.h` to enable `getaddrinfo` support in `Makefile.mk` mingw-w64 builds. This caused disabling support for this unless specifying the value manually. Restore this header and update its comment to tell why we continue to need it. This triggered a regression in official Windows curl builds starting with 8.4.0_1. Fixed in 8.4.0_6. (8.5.0 will be using CMake.)

We enabled them unconditionally (with `ENABLE_THREADED_RESOLVER`). CMake built-in thread detection logic has this condition hard-coded for Windows as well (since at least 2007). Instead of doing all the work of detecting pthread combinations on Windows, then discarding those results, skip these efforts and assume built-in thread support when building for Windows. This saves 1-3 slow CMake configuration steps. Reviewed-by: Daniel Stenberg Closes #12202 - cmake: speed up zstd detection Before this patch we detected the presence of a specific zstd API to see if we can use the library. zstd published that API in its first stable release: v1.0.0 (2016-08-31). Replace that method by detecting the zstd library version instead and accepting if it's v1.0.0 or newer. Also display this detected version and display a warning if the zstd found is unfit for curl. We use the same version detection method as zstd itself, via its public C header. This deviates from autotools which keeps using the slow method of looking for the API by building a test program. The outcome is the same as long as zstd keeps offering this API.

Follow-up to e92edfbef64448ef461117769881f3ed776dec4e #11490 Reviewed-by: Daniel Stenberg Closes #12194 Stefan Eissing (25 Oct 2023) - lib: introduce struct easy_poll_set for poll information Connection filter had a `get_select_socks()` method, inspired by the various `getsocks` functions involved during the lifetime of a transfer. These, depending on transfer state (CONNECT/DO/DONE/ etc.), return sockets to monitor and flag if this shall be done for POLLIN and/or POLLOUT. Due to this design, sockets and flags could only be added, not removed. This led to problems in filters like HTTP/2 where flow control prohibits the sending of data until the peer increases the flow window. The general transfer loop wants to write, adds POLLOUT, the socket is writeable but no data can be written. This leads to cpu busy loops. To prevent that, HTTP/2 did set the `SEND_HOLD` flag of such a blocked transfer, so the transfer loop cedes further attempts. This works if only one such filter is involved. If a HTTP/2 transfer goes through a HTTP/2 proxy, two filters are setting/clearing this flag and may step on each other's toes. Connection filters `get_select_socks()` is replaced by `adjust_pollset()`. They get passed a `struct easy_pollset` that keeps up to `MAX_SOCKSPEREASYHANDLE` sockets and their `POLLIN|POLLOUT` flags. This struct is initialized in `multi_getsock()` by calling the various `getsocks()` implementations based on transfer state, as before. After protocol handlers/transfer loop have set the sockets and flags they want, the `easy_pollset` is *always* passed to the filters. Filters "higher" in the chain are called first, starting at the first not-yet-connection one. Each filter may add sockets and/or change flags. When all flags are removed, the socket itself is removed from the pollset. Example: * transfer wants to send, adds POLLOUT * http/2 filter has a flow control block, removes POLLOUT and adds POLLIN (it is waiting on a WINDOW_UPDATE from the server) * TLS filter is connected and changes nothing * h2-proxy filter also has a flow control block on its tunnel stream, removes POLLOUT and adds POLLIN also. * socket filter is connected and changes nothing * The resulting pollset is then mixed together with all other transfers and their pollsets, just as before. Use of `SEND_HOLD` is no longer necessary in the filters. All filters are adapted for the changed method. The handling in `multi.c` has been adjusted, but its state handling the the protocol handlers' `getsocks` method are untouched. The most affected filters are http/2, ngtcp2, quiche and h2-proxy. TLS filters needed to be adjusted for the connecting handshake read/write handling. No noticeable difference in performance was detected in local scorecard runs.

Closes #12193 Viktor Szakats (24 Oct 2023) - cmake: pre-fill rest of detection values for Windows The goal of this patch is to avoid unnecessary feature detection work when doing Windows builds with CMake. Do this by pre-filling well-known detection results for Windows and specifically for mingw-w64 and MSVC compilers. Also limit feature checks to platforms where the results are actually used. Drop a few redundant ones. And some tidying up. - pre-fill remaining detection values in Windows CMake builds. Based on actual detection results observed in CI runs, preceding similar work over libssh2 and matching up values with `lib/config-win32.h`. This brings down CMake configuration time from 58 to 14 seconds on the same local machine. On AppVeyor CI this translates to: - 128 seconds -> 50 seconds VS2022 MSVC with OpenSSL (per CMake job): https://ci.appveyor.com/project/curlorg/curl/builds/48208419/job/4gw66ecr jpy7necb#L296 https://ci.appveyor.com/project/curlorg/curl/builds/48217440/job/8m4fwrr2 fe249uo8#L186 - 62 seconds -> 16 seconds VS2017 MINGW (per CMake job): https://ci.appveyor.com/project/curlorg/curl/builds/48208419/job/s1y8q5iv lcs7ub29?fullLog=true#L290 https://ci.appveyor.com/project/curlorg/curl/builds/48217440/job/pchpxyjs yc9kl13a?fullLog=true#L194 The formula is about 1-3 seconds delay for each detection. Almost all of these trigger a full compile-link cycle behind the scenes, slow even today, both cross and native, mingw-w64 and apparently MSVC too. Enabling .map files or other custom build features slows it down further. (Similar is expected for autotools configure.) - stop detecting `idn2.h` if idn2 was deselected. autotools does this. - stop detecting `idn2.h` if idn2 was not found. This deviates from autotools. Source code requires both header and lib, so this is still correct, but faster. - limit `ADDRESS_FAMILY` detection to Windows. - normalize `HAVE_WIN32_WINNT` value to lowercase `0x0a12` format. - pre-fill `HAVE_WIN32_WINNT`-dependent detection results. Saving 4 (slow) feature-detections in most builds: `getaddrinfo`, `freeaddrinfo`, `inet_ntop`, `inet_pton` - fix pre-filled `HAVE_SYS_TIME_H`, `HAVE_SYS_PARAM_H`, `HAVE_GETTIMEOFDAY` for mingw-w64. Luckily this do not change build results, as `WIN32` took priority over `HAVE_GETTIMEOFDAY` with the current source code. - limit `HAVE_CLOCK_GETTIME_MONOTONIC_RAW` and `HAVE_CLOCK_GETTIME_MONOTONIC` detections to non-Windows. We're not using these in the source code for Windows. - reduce compiler warning noise in CMake internal logs: - fix to include `winsock2.h` before `windows.h`. Apply it to autotools test snippets too. - delete previous `-D_WINSOCKAPI_=` hack that aimed to fix the above. - cleanup `CMake/CurlTests.c` to emit less warnings. - delete redundant `HAVE_MACRO_SIGSETJMP` feature check. It was the same check as `HAVE_SIGSETJMP`. - delete 'experimental' marking from `CURL_USE_OPENSSL`. - show CMake version via `CMakeLists.txt`.

This caused problems when detecting components with unnecessary dependencies that were not yet built. CMake offers the `CMAKE_REQUIRED_LIBRARIES` variable to set libs used for component checks, which we already use in most cases. That left 4 uses of `check_library_exists_concat()`. Only one of these actually needed the 'concat' feature (ldap/lber). Delete this function and replace it with standard `check_library_exists()` and manual management of our `CURL_LIBS` list we use when linking build targets. And special logic to handle the ldap/lber case. (We have a similar function for headers: `check_include_file_concat()`. It works, but problematic for performance reasons and because it hides the actual headers required in `check_symbol_exists()` calls.)

Prior to this change the SOCKS5 test server did not check that all parts of the handshake were received successfully. If those parts were missing or too short then the server would access uninitialized memory. This issue was discovered in CI job 'memory-sanitizer' test results. Test 2055 was failing due to the SOCKS5 test server not running. It was not running because either it crashed or memory sanitizer aborted it during Test 728. Test 728 connects to the SOCKS5 test server on a redirect but does not send any data on purpose. The test server was not prepared for that.

This is a follow-up to 0dc40b2a. The user can distinguish their easy handle from an internal easy handle by setting CURLOPT_PRIVATE on their easy handle. I had wrongly assumed that meant the user couldn't then set CURLOPT_PRIVATE on an internal handle as well.

Both places which call this function have been updated to handle this change in its contract. The way populate_binsettings had been used prior to this change the huge positive values -- due to signed->unsigned conversion of the potentially negative result of nghttp2_pack_settings_payload which returns negative values on error -- are not possible. But only because http2.c currently always provides a large enough output buffer and provides H2 SETTINGS IVs which pass the verification logic inside nghttp2. If the verification logic were to change or if http2.c started passing in more IVs without increasing the output buffer size, the overflow could become reachable, and libcurl/curl might start leaking memory contents to servers/proxies...

We must make sure that the `memdebug.h` header doesn't apply to `lib/curl_multibyte.c` (as even noted in a comment there.) In unity builds all headers apply to all sources, including `curl_multibyte.c`. This probably resulted in an infinite loop on startup. Exclude this source from unity compilation with TrackMemory enabled, in both libcurl and curl tool. Enable unity mode for a debug Unicode CI job to keep it tested. Also delete the earlier workaround that fully disabled unity for affected builds.

There is an issue with memory tracking and Unicode when built in "unity" mode, which results in the curl tool crashing right on startup, even without any command-line option. Interestingly this doesn't happen under WINE (at least on the system I tested this on), but consistenly happens on real Windows machines. Crash is 0xC0000374 heap corruption. Both shared and static curl executables are affected. This limitation probably won't hit too many people, but it remains a TODO to find and fix the root cause and drop this workaround.

Rewrite in PowerShell: - rewrite MS-DOS batch build script in PowerShell. - move some bash operations into native PowerShell. - fixups for PowerShell insisting on failure when a command outputs something to stderr. - fix to actually run `curl -V` after every build. (and exclude ARM64 builds.) - also say why we skipped `curl -V` if we had to skip. - fix CMake warnings about unused configuration variables, by adapting these dynamically for build cases. - dedupe OpenSSL path into a variable. - disable `test1451` failing with a warning anyway due to missing python impacket. (after trying and failing to install impacket) PowerShell promotes these warnings to errors by PowerShell. We can also suppress they wholesale if they start causing issues in the future, like we already to with `autoreconf` and `./configure`. PowerShell is better than MS-DOS batches, so the hope is this makes it easier to extend and maintain the AppVeyor build logic. POSIX/bash isn't supported inline by AppVeyor on Windows build machines, but we are okay to keep it in an external script, so it's also an option. 2. CI improvements: - enable tests for a "unity" build job. - speed-up CI initialization by using shallow clones of the curl repo. - speed-up CMake MSVC jobs with `TrackFileAccess=false`. - enable parallelism in `VisualStudioSolution` builds. - display CMake version before builds. - always show the CPU in job names. - tell which jobs are build-only in job names. - move `TESTING:` value next to `DISABLED_TESTS:` in two jobs. - add `config.log` (autotools) to dumped logs (need to enable manually). 3. Style: - use single-quotes in YAML like we do in other CI YAML files. It also allows to drop quoting characters and lighter to write/read. (keep double quotes for PowerShell strings needing expansion.) Closes #11999 - cmake: fix `HAVE_LDAP_SSL`, `HAVE_LDAP_URL_PARSE` on non-Windows - set `HAVE_LDAP_URL_PARSE` if `ldap_url_parse` function exists. Before this patch we set it based it on the presence of `stricmp`, which correctly enabled it on e.g. Windows, but was inaccurate for other platforms. - always set `HAVE_LDAP_SSL` if an LDAP backend is detected and LDAPS is not explicitly disabled. This mimics autotools behaviour. Previously we set it only for Windows LDAP. After this fix, LDAPS is correctly enabled in default macOS builds. - enable LDAP[S] for a CMake macOS CI job. Target OS X 10.9 (Mavericks) to avoid deprecation warnings for LDAP API. - always detect `HAVE_LDAP_SSL_H`, even with LDAPS explicitly disabled. This doesn't make much sense, but let's do it to sync behaviour with autotools. - fix benign typo in variable name. Ref: #11964 (effort to sync cmake detections with autotools) Closes #12006 - autotools: restore `HAVE_IOCTL_*` detections This restores `CURL_CHECK_FUNC_IOCTL` detection. I deleted it in 4d73854462f30948acab12984b611e9e33ee41e6 and c3456652a0c72d1845d08df9769667db7e159949 (2022-08), because the `HAVE_IOCTL` result it generated was unused in the source. But, I did miss the fact that this had two dependent checks: `CURL_CHECK_FUNC_IOCTL_FIONBIO`, `CURL_CHECK_FUNC_IOCTL_SIOCGIFADDR` that we do actually need: `HAVE_IOCTL_FIONBIO`, `HAVE_IOCTL_SIOCGIFADDR`.

In CMake we assume we're running on newer systems and enable regardless of OS version. autotools always runs all 3 probes for non-fast-tracked systems and enables this feature if any one of them was successful. To save configuration time, CMake stops at the first successful check. OpenBSD is not fast-tracked and then gets blocklisted as a generic BSD system.

Ref: #11964 Closes #11967 - tool: use our own stderr variable Earlier this year we changed our own stderr variable to use the standard name `stderr` (to avoid bugs where someone is using `stderr` instead of the curl-tool specific variable). This solution needed to override the standard `stderr` symbol via the preprocessor. This in turn didn't play well with unity builds and caused curl tool to crash or stay silent due to an uninitialized stderr. This was a hard to find issue, fixed by manually breaking out one file from the unity sources. To avoid two these two tricks, this patch implements a different solution: Restore using our own local variable for our stderr output and leave `stderr` as-is. To avoid using `stderr` by mistake, add a `checksrc` rule (based on logic we already used in lib for `strerror`) that detects any `stderr` use in `src` and points to using our own variable instead: `tool_stderr`.

If "src[i] << (1 - i % 2 << 3)" is greater than 0x7FFFFFFF, the upper bits of the result will all be 1. 111 words[i/2] |= (src[i] << ((1 - (i % 2)) << 3)); The value will not be greater than 0x7FFFFFFF so this still cannot happen.

When libssh2_userauth_publickey_fromfile_ex returns -1 it does so as a generic error and therefore doesn't set an error message. AFAICT that is not documented behavior. Prior to this change libcurl retrieved the last set error message which would be from a previous function failing. That resulted in misleading auth failed error messages in verbose mode.

Reported-by: calvin2021y on github Fixes #11864 Closes #11869 Dan Fandrich (16 Sep 2023) - http_aws_sigv4: fix sorting with empty parts When comparing with an empty part, the non-empty one is always considered greater-than. Previously, the two would be considered equal which would randomly place empty parts amongst non-empty ones. This showed as a test 439 failure on Solaris as it uses a different implementation of qsort() that compares parts differently. Fixes #11855 Closes #11868 - CI: ignore the "flaky" and "timing-dependent" test results CI builds will now run these tests, but will ignore the results if they fail. The relevant tests are ones that are sensitive to timing or have edge conditions that make them more likely to fail on CI servers, which are often heavily overloaded and slow. This change only adds two additional tests to be ignored, since the others already had the flaky keyword. Closes #11865 - runtests: eliminate a warning on old perl versions The warning "Use of implicit split to @_ is deprecated" showed between perl versions about 5.8 through 5.11. - tests: log the test result code after each libtest This makes it easier to determine the test status. Also, capitalize FAILURE and ABORT messages in log lines to make them easier to spot. Harry Sintonen (16 Sep 2023) - misc: better random strings Generate alphanumerical random strings. Prior this change curl used to create random hex strings. This was mostly okay, but having alphanumerical random strings is better: The strings have more entropy in the same space. The MIME multipart boundary used to be mere 64-bits of randomness due to being 16 hex chars. With these changes the boundary is 22 alphanumerical chars, or little over 130 bits of randomness. Closes #11838 Daniel Stenberg (15 Sep 2023) - cookie: reduce variable scope, add const - cookie: do not store the expire or max-age strings Convert it to an expire time at once and save memory. Closes #11862 - cookie: remove unnecessary struct fields Plus: reduce the hash table size from 256 to 63. It seems unlikely to make much of a speed difference for most use cases but saves 1.5KB of data per instance. Closes #11862 - RELEASE-NOTES: synced Bumped to 8.4.0, the next presumed version Dan Fandrich (14 Sep 2023) - test2600: remove special case handling for USE_ALARM_TIMEOUT This was originally added to handle platforms that supported only 1 second granularity in connect timeouts, but after some recent changes the test currently permafails on several Windows platforms. The need for this special-case was removed in commit 8627416, which increased the connect timeout in all cases to well above 1 second.

Fixes https://github.com/curl/curl/issues/11850 Closes https://github.com/curl/curl/pull/11847 Jay Satiro (14 Sep 2023) - escape: replace Curl_isunreserved with ISUNRESERVED - Use the ALLCAPS version of the macro so that it is clear a macro is being called that evaluates the variable multiple times. - Also capitalize macro isurlpuntcs => ISURLPUNTCS since it evaluates a variable multiple times. This is a follow-up to 291d225a which changed Curl_isunreserved into an alias macro for ISUNRESERVED. The problem is the former is not easily identified as a macro by the caller, which could lead to a bug. For example, ISUNRESERVED(*foo++) is easily identifiable as wrong but Curl_isunreserved(*foo++) is not even though they both are the same. Closes https://github.com/curl/curl/pull/11846 Dan Fandrich (13 Sep 2023) - tests: increase the default server logs lock timeout This timeout is used to wait for the server to finish writing its logs before checking them against the expected values. An overloaded machine could take more than the two seconds previously allocated, so increase the timeout to 5 seconds. Ref: #11328 Closes #11834 - tests: increase TEST_HANG_TIMEOUT in two tests These tests had a 5 second timeout compared to 60 seconds for all other tests. Make these consistent with the others for more reliability on heavily-loaded machines. Ref: #11328 - test1056: disable on Windows This test relies on the IPv6 scope field being ignored when connecting to ipv6-localhost (i.e. [::1%259999] is treated as [::1]). Maybe this is a bit dodgy, but it works on all our test platforms except Windows. This test was disabled manually on all Windows CI builds already, so instead add an incompatible feature and precheck so it's skipped on Windows everywhere automatically. - test587: add a slight delay after test This test is designed to connect to the server, then immediately send a few bytes and disconnect. In some situations, such as on a loaded server, this doesn't give the server enough time to write its lock file before its existence is checked. The test harness then fails to find the server's input log file (because it hasn't been written yet) and fails the test. By adding a short delay after the test, the HTTP server has enough time to write its lock file which gives itself more time to write its remaining files. Ref: #11328 - tests: stop overriding the lock timeout These tests reduce the server lock wait timeout which can increase flakiness on loaded machines. Since this is merely an optimization, eliminate them in favour of reliability. Ref: #11328 - tests: add some --expect100-timeout to reduce timing dependencies These tests can fail when the test machine is so slow that the test HTTP server didn't get a chance to complete before the client's one second 100-continue timeout triggered. Increase that 1 second to 999 seconds so this situation doesn't happen. Ref: #11328 - test661: return from test early in case of curl error - tests: add the timing-dependent keyword on several tests These are ones likely to fail on heavily-loaded machines that alter the normal test timing. Most of these tests already had the flaky keyword since this condition makes them more likely to fail on CI. - test1592: greatly increase the maximum test timeout It was too short to be reliable on heavily loaded CI machines, and as a fail-safe only, it didn't need to be short. Ref: #11328 - test: minor test cleanups Remove an obsolete block of code in tests 2032 & 576. Add a comment in test 1474. - tests: quadruple the %FTPTIME2 and %FTPTIME3 timeouts This gives more of a margin for error when running on overloaded CI servers. Ref: #11328 - tests: improve SLOWDOWN test reliability by reducing sent data These tests are run in SLOWDOWN mode which adds a 10 msec delay after each character output, which means it takes at least 1.6 seconds (and 320 kernel calls) just to get through the long welcome banner. On an overloaded system, this can end up taking much more than 1.6 seconds, and even more than the 7 or 16 second curl timeout that the tests rely on, causing them to fail. Reducing the size of the welcome banner drops the total number of characters sent before the transfer starts by more than half, which reduces the opportunity for test-breaking slowdowns by the same amount.

CERT_CONTEXT from SECPKG_ATTR_REMOTE_CERT_CONTEXT contains end-entity/server certificate in pbCertEncoded. We can use this pointer to determine the order of certificates when enumerating hCertStore using CertEnumCertificatesInStore. This change is to help ensure that the ordering of the certificate chain requested by the user via CURLINFO_CERTINFO has the same ordering on all versions of Windows. Prior to this change Schannel certificate order was reversed in 8986df80 but that was later reverted in f540a39b when it was discovered that Windows 11 22H2 does the reversal on its own.

The DNS host name must be the fully-qualified canonical name of the host. The DNS host name is the preferred form; see notes on server processing of the digest-uri. Realm may not be the host, so we must specify the host explicitly. Note this change only affects the non-SSPI digest code.

It does this by recording the address of any `foreach` task in `hyptransfer->endtask` before pushing it into the executor, and then comparing that against the address of tasks later polled out of the executor. This works right now, but there is no guarantee from hyper that the addresses are stable. `hyper_executor_push` says "The executor takes ownership of the task, which should not be accessed again unless returned back to the user with `hyper_executor_poll`". That wording is a bit ambiguous but with my Rust programmer's hat on I read it as meaning the task returned with `hyper_executor_poll` may be conceptually the same as a task that was pushed, but that there are no other guarantees and comparing addresses is a bad idea. This commit instead uses `hyper_task_set_userdata` to mark the `foreach` task with a `USERDATA_RESP_BODY` value which can then be checked for, removing the need for `hyptransfer->endtask`. This makes the code look more like that hyper C API examples, which use userdata for every task and never look at task addresses.

Closes #11772 Dan Fandrich (31 Aug 2023) - CI: remove Windows builds from Cirrus, without replacement If we don't do this, all coverage on Cirrus will cease in a few days. By removing the Windows builds, the FreeBSD one should still continue as before. The Windows builds will need be moved to another service to maintain test coverage. Closes #11771 - CI: switch macOS ARM build from Cirrus to Circle CI Cirrus is drastically reducing their free tier on Sept. 1, so they will no longer perform all these builds for us. All but one build has been moved, with the LibreSSL one being dropped because of linking problems on Circle. One important note about this change is that Circle CI is currently directing all these builds to x86_64 hardware, despite them requesting ARM. This is because ARM nodes are scheduled to be available on the free tier only in December. This reduces our architectural diversity until then but it should automatically come back once those machines are enabled. - CI: use the right variable for BSD make BSD uses MAKEFLAGS instead of MAKE_FLAGS so it wasn't doing parallel builds before. - CI: drop the FreeBSD 12.X build Cirrus' new free tier won't let us have many builds, so drop the nonessential ones. The FreeBSD 13.X build will still give us the most relevant FreeBSD coverage. - CI: move the Alpine build from Cirrus to GHA Cirrus is reducing their free tier to next to nothing, so we must move builds elsewhere.

The maximum time it is allowed to spend until a connect is confirmed. curl will try to connect to each of the IP adresses returned for the host. Two loops, one for each IP family. During the connect loop, while curl has more than one IP address left to try within a single address family, curl has traditionally allowed (time left/2) for *this* connect attempt. This, to not get stuck on the initial addresses in case the timeout but still allow later addresses to get attempted. This has the downside that when users set a very short timeout and the host has a large number of IP addresses, the effective result might be that every attempt gets a little too short time. This change stop doing the divided-by-two if the total time left is below a threshold. This threshold is 600 milliseconds.

The most important changes: - In `start_CONNECT`, add a missing `hyper_clientconn_free` call on the happy path. - In `start_CONNECT`, add a missing `hyper_request_free` on the error path. - In `bodysend`, add a missing `hyper_body_free` on an early-exit path. - In `bodysend`, remove an unnecessary `hyper_body_free` on a different error path that would cause a double-free. https://docs.rs/hyper/latest/hyper/ffi/fn.hyper_request_set_body.html says of `hyper_request_set_body`: "This takes ownership of the hyper_body *, you must not use it or free it after setting it on the request." This is true even if `hyper_request_set_body` returns an error; I confirmed this by looking at the hyper source code. Other changes are minor but make things slightly nicer.

Since we call SSL_read and SSL_shutdown here, but don't check the return code for an error, we should clear the OpenSSL error queue in case one was raised. This didn't affect curl because we call ERR_clear_error before every write operation (a0dd9df9ab35528eb9eb669e741a5df4b1fb833c), but when libcurl is used in a process with other OpenSSL users, they may detect an OpenSSL error pushed by libcurl's SSL_shutdown as if it was their own.

Jones Bug: https://curl.se/mail/lib-2023-07/0045.html Closes #11557 - Revert "KNOWN_BUGS: build for iOS simulator on macOS 13.2 with Xcode 14" This reverts commit 2e8a3d7cb73c85a9aa151e263315f8a496dbb9d4. It's a user error for supplying incomplete information to the build system. Reported-by: Ryan Schmidt Ref: https://github.com/curl/curl/issues/11215#issuecomment-1658729367 Viktor Szakats (1 Aug 2023) - cmake: add support for single libcurl compilation pass Before this patch CMake builds used two separate compilation passes to build the shared and static libcurl respectively. This patch allows to reduce that to a single pass if the target platform and build settings allow it. This reduces CMake build times when building both static and shared libcurl at the same time, making these dual builds an almost zero-cost option. Enable this feature for Windows builds, where the difference between the two passes was the use of `__declspec(dllexport)` attribute for exported API functions for the shared builds. This patch replaces this method with the use of `libcurl.def` at DLL link time. Also update `Makefile.mk` to use `libcurl.def` to export libcurl API symbols on Windows. This simplifies (or fixes) this build method (e.g. in curl-for-win, which generated a `libcurl.def` from `.h` files using an elaborate set of transformations). `libcurl.def` has the maintenance cost of keeping the list of public libcurl API symbols up-to-date. This list seldom changes, so the cost is low. Closes #11546 - cmake: detect `SSL_set0_wbio` in OpenSSL Present in OpenSSL 1.1.0 and BoringSSL. Missing from LibreSSL 3.8.0. Follow-up to f39472ea9f4f4e12cfbc0500c4580a8d52ce4a59 While here, also fix `RAND_egd()` detection which was broken, likely all along. This feature is probably broken with CMake builds and also requires a sufficiently obsolete OpenSSL version, so this part of the update was not tested. Closes #11555 - cmake: fixup H2 duplicate symbols for unity builds Closes #11550 Pablo Busse (1 Aug 2023) - openssl: Support async cert verify callback - Update the OpenSSL connect state machine to handle SSL_ERROR_WANT_RETRY_VERIFY.

Closes https://github.com/curl/curl/pull/11499 Jay Satiro (1 Aug 2023) - tool_cb_wrt: fix invalid unicode for windows console - Suppress an incomplete UTF-8 sequence at the end of the buffer. - Attempt to reconstruct incomplete UTF-8 sequence from prior call(s) in current call. Prior to this change, in Windows console UTF-8 sequences split between two or more calls to the write callback would cause invalid "replacement characters" U+FFFD to be printed instead of the actual Unicode character. This is because in Windows only UTF-16 encoded characters are printed to the console, therefore we convert the UTF-8 contents to UTF-16, which cannot be done with partial UTF-8 sequences.

Idea: #11400 Suggested-by: ed0d2b2ce19451f2 Closes #11416 - RELEASE-NOTES: synced - tool: add "variable" support Add support for command line variables. Set variables with --variable name=content or --variable name@file (where "file" can be stdin if set to a single dash (-)). Variable content is expanded in option parameters using "{{name}}" (without the quotes) if the option name is prefixed with "--expand-". This gets the contents of the variable "name" inserted, or a blank if the name does not exist as a variable. Insert "{{" verbatim in the string by prefixing it with a backslash, like "\\{{". Import an environment variable with --variable %name. It makes curl exit with an error if the environment variable is not set. It can also rather get a default value if the variable does not exist, using =content or @file like shown above. Example: get the USER environment variable into the URL: --variable %USER --expand-url = "https://example.com/api/{{USER}}/method" When expanding variables, curl supports a set of functions that can make the variable contents more convenient to use. It can trim leading and trailing white space with "trim", output the contents as a JSON quoted string with "json", URL encode it with "url" and base 64 encode it with "b64". To apply functions to a variable expansion, add them colon separated to the right side of the variable. They are then performed in a left to right order. Example: get the contents of a file called $HOME/.secret into a variable called "fix". Make sure that the content is trimmed and percent-encoded sent as POST data: --variable %HOME=/home/default --expand-variable fix@{{HOME}}/.secret --expand-data "{{fix:trim:url}}" https://example.com/ Documented.

Windows does not guarantee a particular certificate ordering, even though TLS may have its own ordering/relationship guarantees. Recent versions of Windows 11 reversed the ordering of ceritifcates returned by CertEnumCertificatesInStore, therefore this commit no longer works as initially intended. libcurl makes no guarantees about certificate ordering if the operating system can't.

It also adds an option to select which one to use when building the curl executable. New build options: - `BUILD_STATIC_LIBS`. Default: `OFF`. Enabled automatically if `BUILD_SHARED_LIBS` is `OFF`. - `BUILD_STATIC_CURL`. Default: `OFF`. Requires `BUILD_STATIC_LIBS` enabled. Enabled automatically if building static libcurl only. - `STATIC_LIB_SUFFIX`. Default: empty. - `IMPORT_LIB_SUFFIX`. Default: `_imp` if implib filename would collide with static lib name (typically with MSVC) in Windows builds. Otherwise empty. Also: - Stop setting the `CURL_STATICLIB` macro via `curl_config.h`, and pass it directly to the compiler. This also allows to delete a condition from `tests/server/CMakeLists.txt`. - Complete a TODO by following the logic used in autotools (also for `LIBCURL_NO_SHARED`), and set `-DCURL_STATICLIB` in `Cflags:` of `libcurl.pc` for _static-only_ curl builds. - Convert an existing CI test to build both shared and static libcurl.

This was caused by cf_socket_close() calling sclose() directly instead of calling socket_close() if the socket was not active. For regular TCP client connections, the socket is activated by cf_socket_active(), which is only called when the socket completes the connect. As far as I can tell, this issue has existed since 7.88.0. That is, since the code in question was introduced by: commit 71b7e0161032927cdfb4e75ea40f65b8898b3956 Author: Stefan Eissing Date: Fri Dec 30 09:14:55 2022 +0100 lib: connect/h2/h3 refactor Closes #11439 Daniel Stenberg (13 Jul 2023) - tool_parsecfg: accept line lengths up to 10M Bumped from 100K set in 47dd957daff9 Reported-by: Antoine du Hamel Fixes #11431 Closes #11435 Stefan Eissing (13 Jul 2023) - CI: brew fix for openssl in default path If brew install/update links openssl into /usr/local, it will be found before anything we add with `-isystem path` to CPP/LDLFAGS.

However, this system call is not thread-safe, and macOS will kill the process if the system call is run first in a fork. To make it possible for the parent process to call this once and prevent the crash, only invoke this system call in the global initialization routine. In addition, this change is beneficial because it: 1. Avoids extra macOS system calls for every IP lookup. 2. Consolidates macOS-specific initialization in a separate file.

Ref: #11328 - runtests: better detect and handle pipe errors in the controller Errors reading and writing to the pipes are now better detected and propagated up to the main test loop so it can be cleanly shut down. Such errors are usually due to a runner dying so it doesn't make much sense to try to continue the test run. - runtests: cleanly abort the runner if the controller dies If the controller dies unexpectedly, have the runner stop its servers and exit cleanly. Otherwise, the orphaned servers will stay running in the background. - runtests: improve error logging Give more information about test harness error conditions to help figure out what might be wrong. Print some internal test state when SIGUSR1 is sent to runtests.pl. Ref: #11328 - runtests: better handle ^C during slow tests Since the SIGINT handler now just sets a flag that must be checked in the main controller loop, make sure that runs periodically. Rather than blocking on a response from a test runner near the end of the test run, add a short timeout to allow it. - runtests: rename server command file The name ftpserver.cmd was historical and has been used for more than ftp for many years now. Rename it to plain server.cmd to reduce confusion. - tests: improve reliability of TFTP tests Stop checking the timeout used by the client under test (for most tests). The timeout will change if the TFTP test server is slow (such as happens on an overprovisioned CI server) because the client will retry and reduce its timeout, and the actual value is not important for most tests. test285 is changed a different way, by increasing the connect timeout. This improves test coverage by allowing the changed timeout value to be checked, but improves reliability with a carefully-chosen timeout that not only allows twice the time to respond as before, but also allows several retries before the client will change its timeout value. Ref: #11328 Daniel Stenberg (19 Jun 2023) - cf-socket: skip getpeername()/getsockname for TFTP Since the socket is not connected then the call fails. When the call fails, failf() is called to write an error message that is then surviving and is returned when the *real* error occurs later. The earlier, incorrect, error therefore hides the actual error message. This could be seen in stderr for test 1007 Test 1007 has now been extended to verify the stderr message.

Bug: https://curl.se/mail/lib-2023-06/0015.html Closes #11272 Reported-by: Pedro Henrique Dan Fandrich (7 Jun 2023) - runtests; give each server a unique log lock file Logs are written by several servers and all of them must be finished writing before the test results can be determined. This means each server must have its own lock file rather than sharing a single one, which is how it was done up to now. Previously, the first server to complete a test would clear the lock before the other server was done, which caused flaky tests. Lock files are now all found in their own directory, so counting locks equals counting the files in that directory. The result is that the proxy logs are now reliably written which actually changes the expected output for two tests.

It means to compile all sources per target as a single C source. This is experimental. You can enable it by passing `-DCMAKE_UNITY_BUILD=ON` to cmake. It requires CMake 3.16 or newer. It makes builds (much) faster, allows for better optimizations and tends to promote less ambiguous code. Also add a new AppVeyor CI job and convert an existing one to use "unity" mode (one MSVC, one MinGW), and enable it for one macOS CI job. Fix related issues: - add missing include guard to `easy_lock.h`. - rename static variables and functions (and a macro) with names reused across sources, or shadowed by local variables. - add an `#undef` after use. - add a missing `#undef` before use. - move internal definitions from `ftp.h` to `ftp.c`. - `curl_memory.h` fixes to make it work when included repeatedly. - stop building/linking curlx bits twice for a static-mode curl tool. These caused doubly defined symbols in unity builds. - silence missing extern declarations compiler warning for ` _CRT_glob`. - fix extern declarations for `tool_freq` and `tool_isVistaOrGreater`. - fix colliding static symbols in debug mode: `debugtime()` and `statename`. - rename `ssl_backend_data` structure to unique names for each TLS-backend, along with the `ssl_connect_data` struct member referencing them. This required adding casts for each access. - add workaround for missing `[P]UNICODE_STRING` types in certain Windows builds when compiling `lib/ldap.c`. To support "unity" builds, we had to enable `SCHANNEL_USE_BLACKLISTS` for Schannel (a Windows `schannel.h` option) _globally_. This caused an indirect inclusion of Windows `schannel.h` from `ldap.c` via `winldap.h` to have it enabled as well. This requires `[P]UNICODE_STRING` types, which is apperantly not defined automatically (as seen with both MSVS and mingw-w64). This patch includes `` to fix it.

Performant values seem to be about 7*num CPU cores, or 1.3*num CPU cores if Valgrind is in use. Flaky tests due to improper log locking (bug #11231) are exacerbated while parallel testing, so it is not enabled by default yet. Fixes #10818 Closes #11246 - runtests: handle repeating tests in multiprocess mode Such as what happens with the --repeat option. Some functions are changed to pass the runner ID instead of relying on the non-unique test number. Ref: #10818 - runtests: buffer logmsg while running singletest() This allows all messages relating to a single test case to be displayed together at the end of the test. Ref: #10818 - runtests: call initserverconfig() in the runner This must be done so variables pick up the runner's unique $LOGDIR. Ref: #10818 - runtests: use a per-runner random seed Each runner needs a unique random seed to reduce the chance of port number collisions. The new scheme uses a consistent per-runner source of randomness which results in deterministic behaviour, as it did before. Ref: #10818 - runtests: complete main test loop refactor for multiple runners The main test loop is now able to handle multiple runners, or no additional runner processes at all. At most one process is still created, however.

Closes #11226 - tests/servers.pm: pick unused port number with a server socket This change replaces the previous method of picking a port number at random to try to start servers on, then retrying up to ten times with new random numbers each time, with a function that creates a server socket on port zero, thereby getting a suitable random port set by the kernel. That server socket is then closed and that port number is used to setup the actual test server on. There is a risk that *another* server can be started on the machine in the time gap, but the server verification feature will detect that. Closes #11220 - RELEASE-NOTES: synced bump to 8.2.0 Alejandro R.

So now we have: ``` NAME="value" export NAME ``` While we're here, make the same change to the two supporting assign+export lines preceeding the script to be consistent with how exports work throughout the rest of configure.ac.

Curl is also libcurl. They are actually individually versioned, but they usually follow each other closely. The version numbering is always built up using the same system: X.Y.Z - X is main version number - Y is release number - Z is patch number ## Bumping numbers One of these numbers will get bumped in each new release. The numbers to the right of a bumped number will be reset to zero. The main version number will get bumped when *really* big, world colliding changes are made. The release number is bumped when changes are performed or things/features are added. The patch number is bumped when the changes are mere bugfixes. It means that after release 1.2.3, we can release 2.0.0 if something really big has been made, 1.3.0 if not that big changes were made or 1.2.4 if only bugs were fixed. Bumping, as in increasing the number with 1, is unconditionally only affecting one of the numbers (except the ones to the right of it, that may be set to zero). 1 becomes 2, 3 becomes 4, 9 becomes 10, 88 becomes 89 and 99 becomes 100. So, after 1.2.9 comes 1.2.10. After 3.99.3, 3.100.0 might come. All original curl source release archives are named according to the libcurl version (not according to the curl client version that, as said before, might differ). As a service to any application that might want to support new libcurl features while still being able to build with older versions, all releases have the libcurl version stored in the `curl/curlver.h` file using a static numbering scheme that can be used for comparison. The version number is defined as: ```c #define LIBCURL_VERSION_NUM 0xXXYYZZ ``` Where `XX`, `YY` and `ZZ` are the main version, release and patch numbers in hexadecimal. All three number fields are always represented using two digits (eight bits each). 1.2 would appear as "0x010200" while version 9.11.7 appears as `0x090b07`. This 6-digit hexadecimal number is always a greater number in a more recent release. It makes comparisons with greater than and less than work. This number is also available as three separate defines: `LIBCURL_VERSION_MAJOR`, `LIBCURL_VERSION_MINOR` and `LIBCURL_VERSION_PATCH`.

MQTT 21.1 Support rate-limiting ============================================================================== 1. libcurl 1.1 TFO support on Windows libcurl supports the CURLOPT_TCP_FASTOPEN option since 7.49.0 for Linux and Mac OS. Windows supports TCP Fast Open starting with Windows 10, version 1607 and we should add support for it. TCP Fast Open is supported on several platforms but not on Windows. Work on this was once started but never finished. See https://github.com/curl/curl/pull/3378 1.2 Consult %APPDATA% also for .netrc %APPDATA%\.netrc is not considered when running on Windows. should not it? See https://github.com/curl/curl/issues/4016 1.3 struct lifreq Use 'struct lifreq' and SIOCGLIFADDR instead of 'struct ifreq' and SIOCGIFADDR on newer Solaris versions as they claim the latter is obsolete. To support IPv6 interface addresses for network interfaces properly. 1.4 Better and more sharing The share interface could benefit from allowing the alt-svc cache to be possible to share between easy handles. See https://github.com/curl/curl/issues/4476 The share interface offers CURL_LOCK_DATA_CONNECT to have multiple easy handle share a connection cache, but due to how connections are used they are still not thread-safe when used shared. See https://github.com/curl/curl/issues/4915 and lib1541.c The share interface offers CURL_LOCK_DATA_HSTS to have multiple easy handle share a HSTS cache, but this is not thread-safe. 1.5 get rid of PATH_MAX Having code use and rely on PATH_MAX is not nice: https://insanecoding.blogspot.com/2007/11/pathmax-simply-isnt.html Currently the libssh2 SSH based code uses it, but to remove PATH_MAX from there we need libssh2 to properly tell us when we pass in a too small buffer and its current API (as of libssh2 1.2.7) does not. 1.6 native IDN support on macOS On recent macOS versions, the getaddrinfo() function itself has built-in IDN support. By setting the AI_CANONNAME flag, the function will return the encoded name in the ai_canonname struct field in the returned information. This could be used by curl on macOS when built without a separate IDN library and an IDN host name is used in a URL. See initial work in https://github.com/curl/curl/pull/5371 1.8 CURLOPT_RESOLVE for any port number This option allows applications to set a replacement IP address for a given host + port pair. Consider making support for providing a replacement address for the host name on all port numbers. See https://github.com/curl/curl/issues/1264 1.9 Cache negative name resolves A name resolve that has failed is likely to fail when made again within a short period of time. Currently we only cache positive responses. 1.10 auto-detect proxy libcurl could be made to detect the system proxy setup automatically and use that. On Windows, macOS and Linux desktops for example. The pull-request to use libproxy for this was deferred due to doubts on the reliability of the dependency and how to use it: https://github.com/curl/curl/pull/977 libdetectproxy is a (C++) library for detecting the proxy on Windows https://github.com/paulharris/libdetectproxy 1.11 minimize dependencies with dynamically loaded modules We can create a system with loadable modules/plug-ins, where these modules would be the ones that link to 3rd party libs. That would allow us to avoid having to load ALL dependencies since only the necessary ones for this app/invoke/used protocols would be necessary to load. See https://github.com/curl/curl/issues/349 1.12 updated DNS server while running If /etc/resolv.conf gets updated while a program using libcurl is running, it is may cause name resolves to fail unless res_init() is called. We should consider calling res_init() + retry once unconditionally on all name resolve failures to mitigate against this. Firefox works like that. Note that Windows does not have res_init() or an alternative. https://github.com/curl/curl/issues/2251 1.13 c-ares and CURLOPT_OPENSOCKETFUNCTION curl will create most sockets via the CURLOPT_OPENSOCKETFUNCTION callback and close them with the CURLOPT_CLOSESOCKETFUNCTION callback. However, c-ares does not use those functions and instead opens and closes the sockets itself. This means that when curl passes the c-ares socket to the CURLMOPT_SOCKETFUNCTION it is not owned by the application like other sockets. See https://github.com/curl/curl/issues/2734 1.15 Monitor connections in the connection pool libcurl's connection cache or pool holds a number of open connections for the purpose of possible subsequent connection reuse. It may contain a few up to a significant amount of connections. Currently, libcurl leaves all connections as they are and first when a connection is iterated over for matching or reuse purpose it is verified that it is still alive. Those connections may get closed by the server side for idleness or they may get an HTTP/2 ping from the peer to verify that they are still alive. By adding monitoring of the connections while in the pool, libcurl can detect dead connections (and close them) better and earlier, and it can handle HTTP/2 pings to keep such ones alive even when not actively doing transfers on them. 1.16 Try to URL encode given URL Given a URL that for example contains spaces, libcurl could have an option that would try somewhat harder than it does now and convert spaces to %20 and perhaps URL encoded byte values over 128 etc (basically do what the redirect following code already does). https://github.com/curl/curl/issues/514 1.17 Add support for IRIs IRIs (RFC 3987) allow localized, non-ascii, names in the URL. To properly support this, curl/libcurl would need to translate/encode the given input from the input string encoding into percent encoded output "over the wire". To make that work smoothly for curl users even on Windows, curl would probably need to be able to convert from several input encodings. 1.18 try next proxy if one does not work Allow an application to specify a list of proxies to try, and failing to connect to the first go on and try the next instead until the list is exhausted. Browsers support this feature at least when they specify proxies using PACs. https://github.com/curl/curl/issues/896 1.19 provide timing info for each redirect curl and libcurl provide timing information via a set of different time-stamps (CURLINFO_*_TIME). When curl is following redirects, those returned time value are the accumulated sums. An improvement could be to offer separate timings for each redirect. https://github.com/curl/curl/issues/6743 1.20 SRV and URI DNS records Offer support for resolving SRV and URI DNS records for libcurl to know which server to connect to for various protocols (including HTTP). 1.21 netrc caching and sharing The netrc file is read and parsed each time a connection is setup, which means that if a transfer needs multiple connections for authentication or redirects, the file might be reread (and parsed) multiple times. This makes it impossible to provide the file as a pipe. 1.22 CURLINFO_PAUSE_STATE Return information about the transfer's current pause state, in both directions. https://github.com/curl/curl/issues/2588 1.23 Offer API to flush the connection pool Sometimes applications want to flush all the existing connections kept alive. An API could allow a forced flush or just a forced loop that would properly close all connections that have been closed by the server already. 1.25 Expose tried IP addresses that failed When libcurl fails to connect to a host, it could offer the application the addresses that were used in the attempt. Source + dest IP, source + dest port and protocol (UDP or TCP) for each failure. Possibly as a callback. Perhaps also provide "reason". https://github.com/curl/curl/issues/2126 1.28 FD_CLOEXEC It sets the close-on-exec flag for the file descriptor, which causes the file descriptor to be automatically (and atomically) closed when any of the exec-family functions succeed. Should probably be set by default? https://github.com/curl/curl/issues/2252 1.29 WebSocket read callback Call the read callback once the connection is established to allow sending the first message in the connection. https://github.com/curl/curl/issues/11402 1.30 config file parsing Consider providing an API, possibly in a separate companion library, for parsing a config file like curl's -K/--config option to allow applications to get the same ability to read curl options from files. See https://github.com/curl/curl/issues/3698 1.31 erase secrets from heap/stack after use Introducing a concept and system to erase secrets from memory after use, it could help mitigate and lessen the impact of (future) security problems etc. However: most secrets are passed to libcurl as clear text from the application and then clearing them within the library adds nothing... https://github.com/curl/curl/issues/7268 1.32 add asynch getaddrinfo support Use getaddrinfo_a() to provide an asynch name resolver backend to libcurl that does not use threads and does not depend on c-ares. The getaddrinfo_a function is (probably?) glibc specific but that is a widely used libc among our users. https://github.com/curl/curl/pull/6746 1.33 make DoH inherit more transfer properties Some options are not inherited because they are not relevant for the DoH SSL connections, or inheriting the option may result in unexpected behavior. For example the user's debug function callback is not inherited because it would be unexpected for internal handles (ie DoH handles) to be passed to that callback. If an option is not inherited then it is not possible to set it separately for DoH without a DoH-specific option. For example: CURLOPT_DOH_SSL_VERIFYHOST, CURLOPT_DOH_SSL_VERIFYPEER and CURLOPT_DOH_SSL_VERIFYSTATUS. See https://github.com/curl/curl/issues/6605 2. libcurl - multi interface 2.1 More non-blocking Make sure we do not ever loop because of non-blocking sockets returning EWOULDBLOCK or similar. Blocking cases include: - Name resolves on non-windows unless c-ares or the threaded resolver is used. - The threaded resolver may block on cleanup: https://github.com/curl/curl/issues/4852 - file:// transfers - TELNET transfers - GSSAPI authentication for FTP transfers - The "DONE" operation (post transfer protocol-specific actions) for the protocols SFTP, SMTP, FTP. Fixing multi_done() for this is a worthy task. - curl_multi_remove_handle for any of the above. See section 2.3. 2.2 Better support for same name resolves If a name resolve has been initiated for name NN and a second easy handle wants to resolve that name as well, make it wait for the first resolve to end up in the cache instead of doing a second separate resolve. This is especially needed when adding many simultaneous handles using the same host name when the DNS resolver can get flooded. 2.3 Non-blocking curl_multi_remove_handle() The multi interface has a few API calls that assume a blocking behavior, like add_handle() and remove_handle() which limits what we can do internally. The multi API need to be moved even more into a single function that "drives" everything in a non-blocking manner and signals when something is done. A remove or add would then only ask for the action to get started and then multi_perform() etc still be called until the add/remove is completed. 2.4 Split connect and authentication process The multi interface treats the authentication process as part of the connect phase. As such any failures during authentication will not trigger the relevant QUIT or LOGOFF for protocols such as IMAP, POP3 and SMTP. 2.5 Edge-triggered sockets should work The multi_socket API should work with edge-triggered socket events. One of the internal actions that need to be improved for this to work perfectly is the 'maxloops' handling in transfer.c:readwrite_data(). 2.6 multi upkeep In libcurl 7.62.0 we introduced curl_easy_upkeep. It unfortunately only works on easy handles. We should introduces a version of that for the multi handle, and also consider doing "upkeep" automatically on connections in the connection pool when the multi handle is in used. See https://github.com/curl/curl/issues/3199 2.7 Virtual external sockets libcurl performs operations on the given file descriptor that presumes it is a socket and an application cannot replace them at the moment. Allowing an application to fully replace those would allow a larger degree of freedom and flexibility. See https://github.com/curl/curl/issues/5835 2.8 dynamically decide to use socketpair For users who do not use curl_multi_wait() or do not care for curl_multi_wakeup(), we could introduce a way to make libcurl NOT create a socketpair in the multi handle. See https://github.com/curl/curl/issues/4829 3. Documentation 3.1 Improve documentation about fork safety See https://github.com/curl/curl/issues/6968 3.2 Provide cmake config-file A config-file package is a set of files provided by us to allow applications to write cmake scripts to find and use libcurl easier. See https://github.com/curl/curl/issues/885 4. FTP 4.1 HOST HOST is a command for a client to tell which host name to use, to offer FTP servers named-based virtual hosting: https://datatracker.ietf.org/doc/html/rfc7151 4.2 Alter passive/active on failure and retry When trying to connect passively to a server which only supports active connections, libcurl returns CURLE_FTP_WEIRD_PASV_REPLY and closes the connection. There could be a way to fallback to an active connection (and vice versa). https://curl.se/bug/feature.cgi?id=1754793 4.3 Earlier bad letter detection Make the detection of (bad) %0d and %0a codes in FTP URL parts earlier in the process to avoid doing a resolve and connect in vain. 4.4 Support CURLOPT_PREQUOTE for dir listings too The lack of support is mostly an oversight and requires the FTP state machine to get updated to get fixed. https://github.com/curl/curl/issues/8602 4.5 ASCII support FTP ASCII transfers do not follow RFC 959. They do not convert the data accordingly. 4.6 GSSAPI via Windows SSPI In addition to currently supporting the SASL GSSAPI mechanism (Kerberos V5) via third-party GSS-API libraries, such as Heimdal or MIT Kerberos, also add support for GSSAPI authentication via Windows SSPI. 4.7 STAT for LIST without data connection Some FTP servers allow STAT for listing directories instead of using LIST, and the response is then sent over the control connection instead of as the otherwise usedw data connection: https://www.nsftools.com/tips/RawFTP.htm#STAT This is not detailed in any FTP specification. 4.8 Passive transfer could try other IP addresses When doing FTP operations through a proxy at localhost, the reported spotted that curl only tried to connect once to the proxy, while it had multiple addresses and a failed connect on one address should make it try the next. After switching to passive mode (EPSV), curl could try all IP addresses for "localhost". Currently it tries ::1, but it should also try 127.0.0.1. See https://github.com/curl/curl/issues/1508 5. HTTP 5.1 Provide the error body from a CONNECT response When curl receives a body response from a CONNECT request to a proxy, it will always just read and ignore it. It would make some users happy if curl instead optionally would be able to make that responsible available. Via a new callback? Through some other means? See https://github.com/curl/curl/issues/9513 5.2 Obey Retry-After in redirects The Retry-After is said to dicate "the minimum time that the user agent is asked to wait before issuing the redirected request" and libcurl does not obey this. See https://github.com/curl/curl/issues/11447 5.3 Rearrange request header order Server implementers often make an effort to detect browser and to reject clients it can detect to not match. One of the last details we cannot yet control in libcurl's HTTP requests, which also can be exploited to detect that libcurl is in fact used even when it tries to impersonate a browser, is the order of the request headers. I propose that we introduce a new option in which you give headers a value, and then when the HTTP request is built it sorts the headers based on that number. We could then have internally created headers use a default value so only headers that need to be moved have to be specified. 5.4 Allow SAN names in HTTP/2 server push curl only allows HTTP/2 push promise if the provided :authority header value exactly matches the host name given in the URL. It could be extended to allow any name that would match the Subject Alternative Names in the server's TLS certificate. See https://github.com/curl/curl/pull/3581 5.5 auth= in URLs Add the ability to specify the preferred authentication mechanism to use by using ;auth= in the login part of the URL. For example: http://test:pass;auth=NTLM@example.com would be equivalent to specifying --user test:pass;auth=NTLM or --user test:pass --ntlm from the command line. Additionally this should be implemented for proxy base URLs as well. 5.6 alt-svc should fallback if alt-svc does not work The alt-svc: header provides a set of alternative services for curl to use instead of the original. If the first attempted one fails, it should try the next etc and if all alternatives fail go back to the original. See https://github.com/curl/curl/issues/4908 5.7 Require HTTP version X or higher curl and libcurl provide options for trying higher HTTP versions (for example HTTP/2) but then still allows the server to pick version 1.1. We could consider adding a way to require a minimum version. See https://github.com/curl/curl/issues/7980 6. TELNET 6.1 ditch stdin Reading input (to send to the remote server) on stdin is a crappy solution for library purposes. We need to invent a good way for the application to be able to provide the data to send. 6.2 ditch telnet-specific select Move the telnet support's network select() loop go away and merge the code into the main transfer loop. Until this is done, the multi interface will not work for telnet. 6.3 feature negotiation debug data Add telnet feature negotiation data to the debug callback as header data. 6.4 exit immediately upon connection if stdin is /dev/null If it did, curl could be used to probe if there is an server there listening on a specific port. That is, the following command would exit immediately after the connection is established with exit code 0: curl -s --connect-timeout 2 telnet://example.com:80 NOTIFY=SUCCESS,FAILURE" ); https://github.com/curl/curl/issues/8232 7.2 Enhanced capability support Add the ability, for an application that uses libcurl, to obtain the list of capabilities returned from the EHLO command. 7.3 Add CURLOPT_MAIL_CLIENT option Rather than use the URL to specify the mail client string to present in the HELO and EHLO commands, libcurl should support a new CURLOPT specifically for specifying this data as the URL is non-standard and to be honest a bit of a hack ;-) Please see the following thread for more information: https://curl.se/mail/lib-2012-05/0178.html 8. POP3 8.2 Enhanced capability support Add the ability, for an application that uses libcurl, to obtain the list of capabilities returned from the CAPA command. 9. IMAP 9.1 Enhanced capability support Add the ability, for an application that uses libcurl, to obtain the list of capabilities returned from the CAPABILITY command. 10. LDAP 10.1 SASL based authentication mechanisms Currently the LDAP module only supports ldap_simple_bind_s() in order to bind to an LDAP server. However, this function sends username and password details using the simple authentication mechanism (as clear text). However, it should be possible to use ldap_bind_s() instead specifying the security context information ourselves. 10.2 CURLOPT_SSL_CTX_FUNCTION for LDAPS CURLOPT_SSL_CTX_FUNCTION works perfectly for HTTPS and email protocols, but it has no effect for LDAPS connections. https://github.com/curl/curl/issues/4108 10.3 Paged searches on LDAP server https://github.com/curl/curl/issues/4452 10.4 Certificate-Based Authentication LDAPS not possible with MAC and Windows with Certificate-Based Authentication https://github.com/curl/curl/issues/9641 11. SMB 11.1 File listing support Add support for listing the contents of a SMB share. The output should probably be the same as/similar to FTP. 11.2 Honor file timestamps The timestamp of the transferred file should reflect that of the original file. 11.3 Use NTLMv2 Currently the SMB authentication uses NTLMv1. 11.4 Create remote directories Support for creating remote directories when uploading a file to a directory that does not exist on the server, just like --ftp-create-dirs. 12. FILE 12.1 Directory listing for FILE: Add support for listing the contents of a directory accessed with FILE. The output should probably be the same as/similar to FTP. 13. TLS 13.1 TLS-PSK with OpenSSL Transport Layer Security pre-shared key ciphersuites (TLS-PSK) is a set of cryptographic protocols that provide secure communication based on pre-shared keys (PSKs). These pre-shared keys are symmetric keys shared in advance among the communicating parties. https://github.com/curl/curl/issues/5081 13.2 Provide mutex locking API Provide a libcurl API for setting mutex callbacks in the underlying SSL library, so that the same application code can use mutex-locking independently of OpenSSL or GnutTLS being used. 13.3 Defeat TLS fingerprinting By changing the order of TLS extensions provided in the TLS handshake, it is sometimes possible to circumvent TLS fingerprinting by servers. The TLS extension order is of course not the only way to fingerprint a client. See https://github.com/curl/curl/issues/8119 13.4 Cache/share OpenSSL contexts "Look at SSL cafile - quick traces look to me like these are done on every request as well, when they should only be necessary once per SSL context (or once per handle)". The major improvement we can rather easily do is to make sure we do not create and kill a new SSL "context" for every request, but instead make one for every connection and reuse that SSL context in the same style connections are reused. It will make us use slightly more memory but it will libcurl do less creations and deletions of SSL contexts. Technically, the "caching" is probably best implemented by getting added to the share interface so that easy handles who want to and can reuse the context specify that by sharing with the right properties set. https://github.com/curl/curl/issues/1110 13.5 Export session ids Add an interface to libcurl that enables "session IDs" to get exported/imported. Cris Bailiff said: "OpenSSL has functions which can serialise the current SSL state to a buffer of your choice, and recover/reset the state from such a buffer at a later date - this is used by mod_ssl for apache to implement and SSL session ID cache". 13.6 Provide callback for cert verification OpenSSL supports a callback for customised verification of the peer certificate, but this does not seem to be exposed in the libcurl APIs. Could it be? There is so much that could be done if it were. 13.7 Less memory massaging with Schannel The Schannel backend does a lot of custom memory management we would rather avoid: the repeated alloc + free in sends and the custom memory + realloc system for encrypted and decrypted data. That should be avoided and reduced for 1) efficiency and 2) safety. 13.8 Support DANE DNS-Based Authentication of Named Entities (DANE) is a way to provide SSL keys and certs over DNS using DNSSEC as an alternative to the CA model. https://www.rfc-editor.org/rfc/rfc6698.txt An initial patch was posted by Suresh Krishnaswamy on March 7th 2013 (https://curl.se/mail/lib-2013-03/0075.html) but it was a too simple approach. See Daniel's comments: https://curl.se/mail/lib-2013-03/0103.html . libunbound may be the correct library to base this development on. BjÃ¶rn Stenberg wrote a separate initial take on DANE that was never completed. 13.9 TLS record padding TLS (1.3) offers optional record padding and OpenSSL provides an API for it. I could make sense for libcurl to offer this ability to applications to make traffic patterns harder to figure out by network traffic observers. See https://github.com/curl/curl/issues/5398 13.10 Support Authority Information Access certificate extension (AIA) AIA can provide various things like CRLs but more importantly information about intermediate CA certificates that can allow validation path to be fulfilled when the HTTPS server does not itself provide them. Since AIA is about downloading certs on demand to complete a TLS handshake, it is probably a bit tricky to get done right. See https://github.com/curl/curl/issues/2793 13.11 Some TLS options are not offered for HTTPS proxies Some TLS related options to the command line tool and libcurl are only provided for the server and not for HTTPS proxies. --proxy-tls-max, --proxy-tlsv1.3, --proxy-curves and a few more.a https://github.com/curl/curl/issues/12286 13.12 Reduce CA certificate bundle reparsing When using the OpenSSL backend, curl will load and reparse the CA bundle at the creation of the "SSL context" when it sets up a connection to do a TLS handshake. A more effective way would be to somehow cache the CA bundle to avoid it having to be repeatedly reloaded and reparsed. See https://github.com/curl/curl/issues/9379 13.13 Make sure we forbid TLS 1.3 post-handshake authentication RFC 8740 explains how using HTTP/2 must forbid the use of TLS 1.3 post-handshake authentication. We should make sure to live up to that. See https://github.com/curl/curl/issues/5396 13.14 Support the clienthello extension Certain stupid networks and middle boxes have a problem with SSL handshake packets that are within a certain size range because how that sets some bits that previously (in older TLS version) were not set. The clienthello extension adds padding to avoid that size range. https://datatracker.ietf.org/doc/html/rfc7685 https://github.com/curl/curl/issues/2299 14. GnuTLS 14.2 check connection Add a way to check if the connection seems to be alive, to correspond to the SSL_peak() way we use with OpenSSL. 15. Schannel 15.1 Extend support for client certificate authentication The existing support for the -E/--cert and --key options could be extended by supplying a custom certificate and key in PEM format, see: - Getting a Certificate for Schannel https://msdn.microsoft.com/en-us/library/windows/desktop/aa375447.aspx 15.2 Extend support for the --ciphers option The existing support for the --ciphers option could be extended by mapping the OpenSSL/GnuTLS cipher suites to the Schannel APIs, see - Specifying Schannel Ciphers and Cipher Strengths https://msdn.microsoft.com/en-us/library/windows/desktop/aa380161.aspx 15.4 Add option to allow abrupt server closure libcurl w/schannel will error without a known termination point from the server (such as length of transfer, or SSL "close notify" alert) to prevent against a truncation attack. Really old servers may neglect to send any termination point. An option could be added to ignore such abrupt closures. https://github.com/curl/curl/issues/4427 16. SASL 16.1 Other authentication mechanisms Add support for other authentication mechanisms such as OLP, GSS-SPNEGO and others. 16.2 Add QOP support to GSSAPI authentication Currently the GSSAPI authentication only supports the default QOP of auth (Authentication), whilst Kerberos V5 supports both auth-int (Authentication with integrity protection) and auth-conf (Authentication with integrity and privacy protection). 17. SSH protocols 17.1 Multiplexing SSH is a perfectly fine multiplexed protocols which would allow libcurl to do multiple parallel transfers from the same host using the same connection, much in the same spirit as HTTP/2 does. libcurl however does not take advantage of that ability but will instead always create a new connection for new transfers even if an existing connection already exists to the host. To fix this, libcurl would have to detect an existing connection and "attach" the new transfer to the existing one. 17.2 Handle growing SFTP files The SFTP code in libcurl checks the file size *before* a transfer starts and then proceeds to transfer exactly that amount of data. If the remote file grows while the transfer is in progress libcurl will not notice and will not adapt. The OpenSSH SFTP command line tool does and libcurl could also just attempt to download more to see if there is more to get... https://github.com/curl/curl/issues/4344 17.3 Read keys from ~/.ssh/id_ecdsa, id_ed25519 The libssh2 backend in curl is limited to only reading keys from id_rsa and id_dsa, which makes it fail connecting to servers that use more modern key types. https://github.com/curl/curl/issues/8586 17.4 Support CURLOPT_PREQUOTE The two other QUOTE options are supported for SFTP, but this was left out for unknown reasons. 17.5 SSH over HTTPS proxy with more backends The SSH based protocols SFTP and SCP did not work over HTTPS proxy at all until PR https://github.com/curl/curl/pull/6021 brought the functionality with the libssh2 backend. Presumably, this support can/could be added for the other backends as well. 17.6 SFTP with SCP:// OpenSSH 9 switched their 'scp' tool to speak SFTP under the hood. Going forward it might be worth having curl or libcurl attempt SFTP if SCP fails to follow suite. 18. Command line tool 18.1 sync "curl --sync http://example.com/feed[1-100].rss" or "curl --sync http://example.net/{index,calendar,history}.html" Downloads a range or set of URLs using the remote name, but only if the remote file is newer than the local file. A Last-Modified HTTP date header should also be used to set the mod date on the downloaded file. 18.2 glob posts Globbing support for -d and -F, as in 'curl -d "name=foo[0-9]" URL'. This is easily scripted though. 18.4 --proxycommand Allow the user to make curl run a command and use its stdio to make requests and not do any network connection by itself. Example: curl --proxycommand 'ssh pi@raspberrypi.local -W 10.1.1.75 80' \ http://some/otherwise/unavailable/service.php See https://github.com/curl/curl/issues/4941 18.5 UTF-8 filenames in Content-Disposition RFC 6266 documents how UTF-8 names can be passed to a client in the Content-Disposition header, and curl does not support this. https://github.com/curl/curl/issues/1888 18.6 Option to make -Z merge lined based outputs on stdout When a user requests multiple lined based files using -Z and sends them to stdout, curl will not "merge" and send complete lines fine but may send partial lines from several sources. https://github.com/curl/curl/issues/5175 18.8 Consider convenience options for JSON and XML? Could we add `--xml` or `--json` to add headers needed to call rest API: `--xml` adds -H 'Content-Type: application/xml' -H "Accept: application/xml" and `--json` adds -H 'Content-Type: application/json' -H "Accept: application/json" Setting Content-Type when doing a GET or any other method without a body would be a bit strange I think - so maybe only add CT for requests with body? Maybe plain `--xml` and ` --json` are a bit too brief and generic. Maybe `--http-json` etc? See https://github.com/curl/curl/issues/5203 18.9 Choose the name of file in braces for complex URLs When using braces to download a list of URLs and you use complicated names in the list of alternatives, it could be handy to allow curl to use other names when saving. Consider a way to offer that. Possibly like {partURL1:name1,partURL2:name2,partURL3:name3} where the name following the colon is the output name. See https://github.com/curl/curl/issues/221 18.10 improve how curl works in a windows console window If you pull the scrollbar when transferring with curl in a Windows console window, the transfer is interrupted and can get disconnected. This can probably be improved. See https://github.com/curl/curl/issues/322 18.11 Windows: set attribute 'archive' for completed downloads The archive bit (FILE_ATTRIBUTE_ARCHIVE, 0x20) separates files that shall be backed up from those that are either not ready or have not changed. Downloads in progress are neither ready to be backed up, nor should they be opened by a different process. Only after a download has been completed it's sensible to include it in any integer snapshot or backup of the system. See https://github.com/curl/curl/issues/3354 18.12 keep running, read instructions from pipe/socket Provide an option that makes curl not exit after the last URL (or even work without a given URL), and then make it read instructions passed on a pipe or over a socket to make further instructions so that a second subsequent curl invoke can talk to the still running instance and ask for transfers to get done, and thus maintain its connection pool, DNS cache and more. 18.13 Ratelimit or wait between serial requests Consider a command line option that can make curl do multiple serial requests slow, potentially with a (random) wait between transfers. There is also a proposed set of standard HTTP headers to let servers let the client adapt to its rate limits: https://www.ietf.org/id/draft-polli-ratelimit-headers-02.html See https://github.com/curl/curl/issues/5406 18.14 --dry-run A command line option that makes curl show exactly what it would do and send if it would run for real. See https://github.com/curl/curl/issues/5426 18.15 --retry should resume When --retry is used and curl actually retries transfer, it should use the already transferred data and do a resumed transfer for the rest (when possible) so that it does not have to transfer the same data again that was already transferred before the retry. See https://github.com/curl/curl/issues/1084 18.16 send only part of --data When the user only wants to send a small piece of the data provided with --data or --data-binary, like when that data is a huge file, consider a way to specify that curl should only send a piece of that. One suggested syntax would be: "--data-binary @largefile.zip!1073741823-2147483647". See https://github.com/curl/curl/issues/1200 18.17 consider file name from the redirected URL with -O ? When a user gives a URL and uses -O, and curl follows a redirect to a new URL, the file name is not extracted and used from the newly redirected-to URL even if the new URL may have a much more sensible file name. This is clearly documented and helps for security since there is no surprise to users which file name that might get overwritten. But maybe a new option could allow for this or maybe -J should imply such a treatment as well as -J already allows for the server to decide what file name to use so it already provides the "may overwrite any file" risk. This is extra tricky if the original URL has no file name part at all since then the current code path will error out with an error message, and we cannot *know* already at that point if curl will be redirected to a URL that has a file name... See https://github.com/curl/curl/issues/1241 18.18 retry on network is unreachable The --retry option retries transfers on "transient failures". We later added --retry-connrefused to also retry for "connection refused" errors. Suggestions have been brought to also allow retry on "network is unreachable" errors and while totally reasonable, maybe we should consider a way to make this more configurable than to add a new option for every new error people want to retry for? https://github.com/curl/curl/issues/1603 18.19 expand ~/ in config files For example .curlrc could benefit from being able to do this. See https://github.com/curl/curl/issues/2317 18.20 host name sections in config files config files would be more powerful if they could set different configurations depending on used URLs, host name or possibly origin. Then a default .curlrc could a specific user-agent only when doing requests against a certain site. 18.21 retry on the redirected-to URL When curl is told to --retry a failed transfer and follows redirects, it might get an HTTP 429 response from the redirected-to URL and not the original one, which then could make curl decide to rather retry the transfer on that URL only instead of the original operation to the original URL. Perhaps extra emphasized if the original transfer is a large POST that redirects to a separate GET, and that GET is what gets the 529 See https://github.com/curl/curl/issues/5462 18.23 Set the modification date on an uploaded file For SFTP and possibly FTP, curl could offer an option to set the modification time for the uploaded file. See https://github.com/curl/curl/issues/5768 18.24 Use multiple parallel transfers for a single download To enhance transfer speed, downloading a single URL can be split up into multiple separate range downloads that get combined into a single final result. An ideal implementation would not use a specified number of parallel transfers, but curl could: - First start getting the full file as transfer A - If after N seconds have passed and the transfer is expected to continue for M seconds or more, add a new transfer (B) that asks for the second half of A's content (and stop A at the middle). - If splitting up the work improves the transfer rate, it could then be done again. Then again, etc up to a limit. This way, if transfer B fails (because Range: is not supported) it will let transfer A remain the single one. N and M could be set to some sensible defaults. See https://github.com/curl/curl/issues/5774 18.25 Prevent terminal injection when writing to terminal curl could offer an option to make escape sequence either non-functional or avoid cursor moves or similar to reduce the risk of a user getting tricked by clever tricks. See https://github.com/curl/curl/issues/6150 18.26 Custom progress meter update interval Users who are for example doing large downloads in CI or remote setups might want the occasional progress meter update to see that the transfer is progressing and has not stuck, but they may not appreciate the many-times-a-second frequency curl can end up doing it with now. 18.27 -J and -O with %-encoded file names -J/--remote-header-name does not decode %-encoded file names. RFC 6266 details how it should be done. The can of worm is basically that we have no charset handling in curl and ascii >=128 is a challenge for us. Not to mention that decoding also means that we need to check for nastiness that is attempted, like "../" sequences and the like. Probably everything to the left of any embedded slashes should be cut off. https://curl.se/bug/view.cgi?id=1294 -O also does not decode %-encoded names, and while it has even less information about the charset involved the process is similar to the -J case. Note that we will not add decoding to -O without the user asking for it with some other means as well, since -O has always been documented to use the name exactly as specified in the URL. 18.28 -J with -C - When using -J (with -O), automatically resumed downloading together with "-C -" fails. Without -J the same command line works. This happens because the resume logic is worked out before the target file name (and thus its pre-transfer size) has been figured out. This can be improved. https://curl.se/bug/view.cgi?id=1169 18.29 --retry and transfer timeouts If using --retry and the transfer timeouts (possibly due to using -m or -y/-Y) the next attempt does not resume the transfer properly from what was downloaded in the previous attempt but will truncate and restart at the original position where it was at before the previous failed attempt. See https://curl.se/mail/lib-2008-01/0080.html and Mandriva bug report https://qa.mandriva.com/show_bug.cgi?id=22565 19. Build 19.1 roffit Consider extending 'roffit' to produce decent ASCII output, and use that instead of (g)nroff when building src/tool_hugehelp.c 19.2 Enable PIE and RELRO by default Especially when having programs that execute curl via the command line, PIE renders the exploitation of memory corruption vulnerabilities a lot more difficult. This can be attributed to the additional information leaks being required to conduct a successful attack. RELRO, on the other hand, masks different binary sections like the GOT as read-only and thus kills a handful of techniques that come in handy when attackers are able to arbitrarily overwrite memory. A few tests showed that enabling these features had close to no impact, neither on the performance nor on the general functionality of curl. 19.3 Do not use GNU libtool on OpenBSD When compiling curl on OpenBSD with "--enable-debug" it will give linking errors when you use GNU libtool. This can be fixed by using the libtool provided by OpenBSD itself. However for this the user always needs to invoke make with "LIBTOOL=/usr/bin/libtool". It would be nice if the script could have some magic to detect if this system is an OpenBSD host and then use the OpenBSD libtool instead. See https://github.com/curl/curl/issues/5862 19.4 Package curl for Windows in a signed installer See https://github.com/curl/curl/issues/5424 19.5 make configure use --cache-file more and better The configure script can be improved to cache more values so that repeated invokes run much faster. See https://github.com/curl/curl/issues/7753 19.6 build curl with Windows Unicode support The user wants an easier way to tell autotools to build curl with Windows Unicode support, like ./configure --enable-windows-unicode See https://github.com/curl/curl/issues/7229 20. Test suite 20.1 SSL tunnel Make our own version of stunnel for simple port forwarding to enable HTTPS and FTP-SSL tests without the stunnel dependency, and it could allow us to provide test tools built with either OpenSSL or GnuTLS 20.2 nicer lacking perl message If perl was not found by the configure script, do not attempt to run the tests but explain something nice why it does not. 20.3 more protocols supported Extend the test suite to include more protocols. The telnet could just do FTP or http operations (for which we have test servers). 20.4 more platforms supported Make the test suite work on more platforms. OpenBSD and Mac OS. Remove fork()s and it should become even more portable. 20.5 Add support for concurrent connections Tests 836, 882 and 938 were designed to verify that separate connections are not used when using different login credentials in protocols that should not reuse a connection under such circumstances. Unfortunately, ftpserver.pl does not appear to support multiple concurrent connections. The read while() loop seems to loop until it receives a disconnect from the client, where it then enters the waiting for connections loop. When the client opens a second connection to the server, the first connection has not been dropped (unless it has been forced - which we should not do in these tests) and thus the wait for connections loop is never entered to receive the second connection. 20.6 Use the RFC 6265 test suite A test suite made for HTTP cookies (RFC 6265) by Adam Barth is available at https://github.com/abarth/http-state/tree/master/tests It'd be really awesome if someone would write a script/setup that would run curl with that test suite and detect deviances. Ideally, that would even be incorporated into our regular test suite. 20.7 Support LD_PRELOAD on macOS LD_RELOAD does not work on macOS, but there are tests which require it to run properly. Look into making the preload support in runtests.pl portable such that it uses DYLD_INSERT_LIBRARIES on macOS. 20.8 Run web-platform-tests URL tests Run web-platform-tests URL tests and compare results with browsers on wpt.fyi It would help us find issues to fix and help us document where our parser differs from the WHATWG URL spec parsers. See https://github.com/curl/curl/issues/4477 21. MQTT 21.1 Support rate-limiting The rate-limiting logic is done in the PERFORMING state in multi.c but MQTT is not (yet) implemented to use that.

HTTP/3 18.1 connection migration does not work ============================================================================== 1. HTTP 1.2 hyper is slow When curl is built to use hyper for HTTP, it is unnecessary slow. https://github.com/curl/curl/issues/11203 1.5 Expect-100 meets 417 If an upload using Expect: 100-continue receives an HTTP 417 response, it ought to be automatically resent without the Expect:. A workaround is for the client application to redo the transfer after disabling Expect:. https://curl.se/mail/archive-2008-02/0043.html 2. TLS 2.3 Unable to use PKCS12 certificate with Secure Transport See https://github.com/curl/curl/issues/5403 2.4 Secure Transport will not import PKCS#12 client certificates without a password libcurl calls SecPKCS12Import with the PKCS#12 client certificate, but that function rejects certificates that do not have a password. https://github.com/curl/curl/issues/1308 2.5 Client cert handling with Issuer DN differs between backends When the specified client certificate does not match any of the server-specified DNs, the OpenSSL and GnuTLS backends behave differently. The github discussion may contain a solution. See https://github.com/curl/curl/issues/1411 2.7 Client cert (MTLS) issues with Schannel See https://github.com/curl/curl/issues/3145 2.11 Schannel TLS 1.2 handshake bug in old Windows versions In old versions of Windows such as 7 and 8.1 the Schannel TLS 1.2 handshake implementation likely has a bug that can rarely cause the key exchange to fail, resulting in error SEC_E_BUFFER_TOO_SMALL or SEC_E_MESSAGE_ALTERED. https://github.com/curl/curl/issues/5488 2.12 FTPS with Schannel times out file list operation "Instead of the command completing, it just sits there until the timeout expires." - the same command line seems to work with other TLS backends and other operating systems. See https://github.com/curl/curl/issues/5284. 2.13 CURLOPT_CERTINFO results in CURLE_OUT_OF_MEMORY with Schannel https://github.com/curl/curl/issues/8741 3. Email protocols 3.1 IMAP SEARCH ALL truncated response IMAP "SEARCH ALL" truncates output on large boxes. "A quick search of the code reveals that pingpong.c contains some truncation code, at line 408, when it deems the server response to be too large truncating it to 40 characters" https://curl.se/bug/view.cgi?id=1366 3.2 No disconnect command The disconnect commands (LOGOUT and QUIT) may not be sent by IMAP, POP3 and SMTP if a failure occurs during the authentication phase of a connection. 3.3 POP3 expects "CRLF.CRLF" eob for some single-line responses You have to tell libcurl not to expect a body, when dealing with one line response commands. Please see the POP3 examples and test cases which show this for the NOOP and DELE commands. https://curl.se/bug/?i=740 3.4 AUTH PLAIN for SMTP is not working on all servers Specifying "--login-options AUTH=PLAIN" on the command line does not seem to work correctly. See https://github.com/curl/curl/issues/4080 3.5 APOP authentication fails on POP3 See https://github.com/curl/curl/issues/10073 4. Command line 5. Build and portability issues 5.1 OS400 port requires deprecated IBM library curl for OS400 requires QADRT to build, which provides ASCII wrappers for libc/POSIX functions in the ILE, but IBM no longer supports or even offers this library to download. See https://github.com/curl/curl/issues/5176 5.2 curl-config --libs contains private details "curl-config --libs" will include details set in LDFLAGS when configure is run that might be needed only for building libcurl. Further, curl-config --cflags suffers from the same effects with CFLAGS/CPPFLAGS. 5.3 building for old macOS fails with gcc Building curl for certain old macOS versions fails when gcc is used. We command using clang in those cases. See https://github.com/curl/curl/issues/11441 5.5 cannot handle Unicode arguments in non-Unicode builds on Windows If a URL or filename cannot be encoded using the user's current codepage then it can only be encoded properly in the Unicode character set. Windows uses UTF-16 encoding for Unicode and stores it in wide characters, however curl and libcurl are not equipped for that at the moment except when built with _UNICODE and UNICODE defined. And, except for Cygwin, Windows cannot use UTF-8 as a locale. https://curl.se/bug/?i=345 https://curl.se/bug/?i=731 https://curl.se/bug/?i=3747 5.6 cygwin: make install installs curl-config.1 twice https://github.com/curl/curl/issues/8839 5.9 Utilize Requires.private directives in libcurl.pc https://github.com/curl/curl/issues/864 5.11 configure --with-gssapi with Heimdal is ignored on macOS ... unless you also pass --with-gssapi-libs https://github.com/curl/curl/issues/3841 5.12 flaky CI builds We run many CI builds for each commit and PR on github, and especially a number of the Windows builds are flaky. This means that we rarely get all CI builds go green and complete without errors. This is unfortunate as it makes us sometimes miss actual build problems and it is surprising to newcomers to the project who (rightfully) do not expect this. See https://github.com/curl/curl/issues/6972 5.13 long paths are not fully supported on Windows curl on Windows cannot access long paths (paths longer than 260 characters). However, as a workaround, the Windows path prefix \\?\ which disables all path interpretation may work to allow curl to access the path. For example: \\?\c:\longpath. See https://github.com/curl/curl/issues/8361 5.14 Windows Unicode builds use homedir in current locale The Windows Unicode builds of curl use the current locale, but expect Unicode UTF-8 encoded paths for internal use such as open, access and stat. The user's home directory is retrieved via curl_getenv in the current locale and not as UTF-8 encoded Unicode. See https://github.com/curl/curl/pull/7252 and https://github.com/curl/curl/pull/7281 6. Authentication 6.1 NTLM authentication and unicode NTLM authentication involving unicode user name or password only works properly if built with UNICODE defined together with the Schannel backend. The original problem was mentioned in: https://curl.se/mail/lib-2009-10/0024.html https://curl.se/bug/view.cgi?id=896 The Schannel version verified to work as mentioned in https://curl.se/mail/lib-2012-07/0073.html 6.2 MIT Kerberos for Windows build libcurl fails to build with MIT Kerberos for Windows (KfW) due to KfW's library header files exporting symbols/macros that should be kept private to the KfW library. See ticket #5601 at https://krbdev.mit.edu/rt/ 6.3 NTLM in system context uses wrong name NTLM authentication using SSPI (on Windows) when (lib)curl is running in "system context" will make it use wrong(?) user name - at least when compared to what winhttp does. See https://curl.se/bug/view.cgi?id=535 6.5 NTLM does not support password with Â§ character https://github.com/curl/curl/issues/2120 6.6 libcurl can fail to try alternatives with --proxy-any When connecting via a proxy using --proxy-any, a failure to establish an authentication will cause libcurl to abort trying other options if the failed method has a higher preference than the alternatives. As an example, --proxy-any against a proxy which advertise Negotiate and NTLM, but which fails to set up Kerberos authentication will not proceed to try authentication using NTLM. https://github.com/curl/curl/issues/876 6.7 Do not clear digest for single realm https://github.com/curl/curl/issues/3267 6.9 SHA-256 digest not supported in Windows SSPI builds Windows builds of curl that have SSPI enabled use the native Windows API calls to create authentication strings. The call to InitializeSecurityContext fails with SEC_E_QOP_NOT_SUPPORTED which causes curl to fail with CURLE_AUTH_ERROR. Microsoft does not document supported digest algorithms and that SEC_E error code is not a documented error for InitializeSecurityContext (digest). https://github.com/curl/curl/issues/6302 6.10 curl never completes Negotiate over HTTP Apparently it is not working correctly...? See https://github.com/curl/curl/issues/5235 6.11 Negotiate on Windows fails When using --negotiate (or NTLM) with curl on Windows, SSL/TLS handshake fails despite having a valid kerberos ticket cached. Works without any issue in Unix/Linux. https://github.com/curl/curl/issues/5881 6.12 cannot use Secure Transport with Crypto Token Kit https://github.com/curl/curl/issues/7048 6.13 Negotiate authentication against Hadoop HDFS https://github.com/curl/curl/issues/8264 7. FTP 7.3 FTP with NOBODY and FAILONERROR It seems sensible to be able to use CURLOPT_NOBODY and CURLOPT_FAILONERROR with FTP to detect if a file exists or not, but it is not working: https://curl.se/mail/lib-2008-07/0295.html 7.4 FTP with ACCT When doing an operation over FTP that requires the ACCT command (but not when logging in), the operation will fail since libcurl does not detect this and thus fails to issue the correct command: https://curl.se/bug/view.cgi?id=635 7.11 FTPS upload data loss with TLS 1.3 During FTPS upload curl does not attempt to read TLS handshake messages sent after the initial handshake. OpenSSL servers running TLS 1.3 may send such a message. When curl closes the upload connection if unread data has been received (such as a TLS handshake message) then the TCP protocol sends an RST to the server, which may cause the server to discard or truncate the upload if it has not read all sent data yet, and then return an error to curl on the control channel connection. Since 7.78.0 this is mostly fixed. curl will do a single read before closing TLS connections (which causes the TLS library to read handshake messages), however there is still possibility of an RST if more messages need to be read or a message arrives after the read but before close (network race condition). https://github.com/curl/curl/issues/6149 7.12 FTPS directory listing hangs on Windows with Schannel https://github.com/curl/curl/issues/9161 9. SFTP and SCP 9.1 SFTP does not do CURLOPT_POSTQUOTE correct When libcurl sends CURLOPT_POSTQUOTE commands when connected to a SFTP server using the multi interface, the commands are not being sent correctly and instead the connection is "cancelled" (the operation is considered done) prematurely. There is a half-baked (busy-looping) patch provided in the bug report but it cannot be accepted as-is. See https://curl.se/bug/view.cgi?id=748 9.2 wolfssh: publickey auth does not work When building curl to use the wolfSSH backend for SFTP, the publickey authentication does not work. This is simply functionality not written for curl yet, the necessary API for make this work is provided by wolfSSH. See https://github.com/curl/curl/issues/4820 9.3 Remote recursive folder creation with SFTP On this servers, the curl fails to create directories on the remote server even when the CURLOPT_FTP_CREATE_MISSING_DIRS option is set. See https://github.com/curl/curl/issues/5204 9.4 libssh blocking and infinite loop problem In the SSH_SFTP_INIT state for libssh, the ssh session working mode is set to blocking mode. If the network is suddenly disconnected during sftp transmission, curl will be stuck, even if curl is configured with a timeout. https://github.com/curl/curl/issues/8632 9.5 cygwin: "WARNING: UNPROTECTED PRIVATE KEY FILE!" Running SCP and SFTP tests on cygwin makes this warning message appear. https://github.com/curl/curl/issues/11244 10. SOCKS 10.3 FTPS over SOCKS libcurl does not support FTPS over a SOCKS proxy. 11. Internals 11.2 error buffer not set if connection to multiple addresses fails If you ask libcurl to resolve a hostname like example.com to IPv6 addresses only. But you only have IPv4 connectivity. libcurl will correctly fail with CURLE_COULDNT_CONNECT. But the error buffer set by CURLOPT_ERRORBUFFER remains empty. Issue: https://github.com/curl/curl/issues/544 11.4 HTTP test server 'connection-monitor' problems The 'connection-monitor' feature of the sws HTTP test server does not work properly if some tests are run in unexpected order. Like 1509 and then 1525. See https://github.com/curl/curl/issues/868 11.5 Connection information when using TCP Fast Open CURLINFO_LOCAL_PORT (and possibly a few other) fails when TCP Fast Open is enabled. See https://github.com/curl/curl/issues/1332 and https://github.com/curl/curl/issues/4296 12. LDAP 12.1 OpenLDAP hangs after returning results By configuration defaults, OpenLDAP automatically chase referrals on secondary socket descriptors. The OpenLDAP backend is asynchronous and thus should monitor all socket descriptors involved. Currently, these secondary descriptors are not monitored, causing OpenLDAP library to never receive data from them. As a temporary workaround, disable referrals chasing by configuration. The fix is not easy: proper automatic referrals chasing requires a synchronous bind callback and monitoring an arbitrary number of socket descriptors for a single easy handle (currently limited to 5). Generic LDAP is synchronous: OK. See https://github.com/curl/curl/issues/622 and https://curl.se/mail/lib-2016-01/0101.html 12.2 LDAP on Windows does authentication wrong? https://github.com/curl/curl/issues/3116 12.3 LDAP on Windows does not work A simple curl command line getting "ldap://ldap.forumsys.com" returns an error that says "no memory" ! https://github.com/curl/curl/issues/4261 12.4 LDAPS requests to ActiveDirectory server hang https://github.com/curl/curl/issues/9580 13. TCP/IP 13.2 Trying local ports fails on Windows This makes '--local-port [range]' to not work since curl cannot properly detect if a port is already in use, so it will try the first port, use that and then subsequently fail anyway if that was actually in use. https://github.com/curl/curl/issues/8112 15. CMake 15.1 cmake outputs: no version information available Something in the SONAME generation seems to be wrong in the cmake build. https://github.com/curl/curl/issues/11158 15.2 support build with GnuTLS 15.3 unusable tool_hugehelp.c with MinGW see https://github.com/curl/curl/issues/3125 15.4 build docs/curl.1 The cmake build does not create the docs/curl.1 file and therefore must rely on it being there already. This makes the --manual option not work and test cases like 1139 cannot function. 15.6 uses -lpthread instead of Threads::Threads See https://github.com/curl/curl/issues/6166 15.7 generated .pc file contains strange entries The Libs.private field of the generated .pc file contains -lgcc -lgcc_s -lc -lgcc -lgcc_s See https://github.com/curl/curl/issues/6167 15.8 libcurl.pc uses absolute library paths The libcurl.pc file generated by cmake contains things like Libs.private: /usr/lib64/libssl.so /usr/lib64/libcrypto.so /usr/lib64/libz.so. The autotools equivalent would say Libs.private: -lssl -lcrypto -lz See https://github.com/curl/curl/issues/6169 15.11 ExternalProject_Add does not set CURL_CA_PATH CURL_CA_BUNDLE and CURL_CA_PATH are not set properly when cmake's ExternalProject_Add is used to build curl as a dependency. See https://github.com/curl/curl/issues/6313 15.13 CMake build with MIT Kerberos does not work Minimum CMake version was bumped in curl 7.71.0 (#5358) Since CMake 3.2 try_compile started respecting the CMAKE_EXE_FLAGS. The code dealing with MIT Kerberos detection sets few variables to potentially weird mix of space, and ;-separated flags. It had to blow up at some point. All the CMake checks that involve compilation are doomed from that point, the configured tree cannot be built. https://github.com/curl/curl/issues/6904 16. aws-sigv4 16.1 aws-sigv4 does not sign requests with * correctly https://github.com/curl/curl/issues/7559 16.6 aws-sigv4 does not behave well with AWS VPC Lattice https://github.com/curl/curl/issues/11007 17. HTTP/2 17.2 HTTP/2 frames while in the connection pool kill reuse If the server sends HTTP/2 frames (like for example an HTTP/2 PING frame) to curl while the connection is held in curl's connection pool, the socket will be found readable when considered for reuse and that makes curl think it is dead and then it will be closed and a new connection gets created instead. This is *best* fixed by adding monitoring to connections while they are kept in the pool so that pings can be responded to appropriately. 17.3 ENHANCE_YOUR_CALM causes infinite retries Infinite retries with 2 parallel requests on one connection receiving GOAWAY with ENHANCE_YOUR_CALM error code. See https://github.com/curl/curl/issues/5119 18. HTTP/3 18.1 connection migration does not work https://github.com/curl/curl/issues/7695 PK!Us6@@COPYINGnu„[µü¤COPYRIGHT AND PERMISSION NOTICE Copyright (c) 1996 - 2023, Daniel Stenberg, , and many contributors, see the THANKS file.

PHP/CURL Issues 7.1 What is PHP/CURL? 7.2 Who wrote PHP/CURL? 7.3 Can I perform multiple requests using the same handle? 7.4 Does PHP/CURL have dependencies? 8. Development 8.1 Why does curl use C89? 8.2 Will curl be rewritten? ============================================================================== 1. Philosophy 1.1 What is cURL? cURL is the name of the project. The name is a play on 'Client for URLs', originally with URL spelled in uppercase to make it obvious it deals with URLs. The fact it can also be read as 'see URL' also helped, it works as an abbreviation for "Client URL Request Library" or why not the recursive version: "curl URL Request Library". The cURL project produces two products: libcurl A client-side URL transfer library, supporting DICT, FILE, FTP, FTPS, GOPHER, GOPHERS, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, MQTT, POP3, POP3S, RTMP, RTMPS, RTSP, SCP, SFTP, SMB, SMBS, SMTP, SMTPS, TELNET, TFTP, WS and WSS. libcurl supports HTTPS certificates, HTTP POST, HTTP PUT, FTP uploading, Kerberos, SPNEGO, HTTP form based upload, proxies, cookies, user+password authentication, file transfer resume, http proxy tunneling and more. libcurl is highly portable, it builds and works identically on numerous platforms, including Solaris, NetBSD, FreeBSD, OpenBSD, Darwin, HP-UX, IRIX, AIX, Tru64, Linux, UnixWare, HURD, Windows, Amiga, OS/2, macOS, Ultrix, QNX, OpenVMS, RISC OS, Novell NetWare, DOS, Symbian, OSF, Android, Minix, IBM TPF and more... libcurl is free, thread-safe, IPv6 compatible, feature rich, well supported and fast. curl A command line tool for getting or sending data using URL syntax. Since curl uses libcurl, curl supports the same wide range of common Internet protocols that libcurl does. We pronounce curl with an initial k sound. It rhymes with words like girl and earl. This is a short WAV file to help you: https://media.merriam-webster.com/soundc11/c/curl0001.wav There are numerous sub-projects and related projects that also use the word curl in the project names in various combinations, but you should take notice that this FAQ is directed at the command-line tool named curl (and libcurl the library), and may therefore not be valid for other curl-related projects. (There is however a small section for the PHP/CURL in this FAQ.) 1.2 What is libcurl? libcurl is a reliable and portable library for doing Internet data transfers using one or more of its supported Internet protocols. You can use libcurl freely in your application, be it open source, commercial or closed-source. libcurl is most probably the most portable, most powerful and most often used C-based multi-platform file transfer library on this planet - be it open source or commercial. 1.3 What is curl not? curl is not a wget clone. That is a common misconception. Never, during curl's development, have we intended curl to replace wget or compete on its market. curl is targeted at single-shot file transfers. curl is not a website mirroring program. If you want to use curl to mirror something: fine, go ahead and write a script that wraps around curl or use libcurl to make it reality. curl is not an FTP site mirroring program. Sure, get and send FTP with curl but if you want systematic and sequential behavior you should write a script (or write a new program that interfaces libcurl) and do it. curl is not a PHP tool, even though it works perfectly well when used from or with PHP (when using the PHP/CURL module). curl is not a program for a single operating system. curl exists, compiles, builds and runs under a wide range of operating systems, including all modern Unixes (and a bunch of older ones too), Windows, Amiga, OS/2, macOS, QNX etc. 1.4 When will you make curl do XXXX ? We love suggestions of what to change in order to make curl and libcurl better. We do however believe in a few rules when it comes to the future of curl: curl -- the command line tool -- is to remain a non-graphical command line tool. If you want GUIs or fancy scripting capabilities, you should look for another tool that uses libcurl. We do not add things to curl that other small and available tools already do well at the side. curl's output can be piped into another program or redirected to another file for the next program to interpret. We focus on protocol related issues and improvements. If you want to do more magic with the supported protocols than curl currently does, chances are good we will agree. If you want to add more protocols, we may agree. If you want someone else to do all the work while you wait for us to implement it for you, that is not a friendly attitude. We spend a considerable time already on maintaining and developing curl. In order to get more out of us, you should consider trading in some of your time and effort in return. Simply go to the GitHub repository which resides at https://github.com/curl/curl, fork the project, and create pull requests with your proposed changes. If you write the code, chances are better that it will get into curl faster. 1.5 Who makes curl? curl and libcurl are not made by any single individual. Daniel Stenberg is project leader and main developer, but other persons' submissions are important and crucial. Anyone can contribute and post their changes and improvements and have them inserted in the main sources (of course on the condition that developers agree that the fixes are good). The full list of all contributors is found in the docs/THANKS file. curl is developed by a community, with Daniel at the wheel. 1.6 What do you get for making curl? Project cURL is entirely free and open. We do this voluntarily, mostly in our spare time. Companies may pay individual developers to work on curl. This is not controlled by nor supervised in any way by the curl project. We get help from companies. Haxx provides website, bandwidth, mailing lists etc, GitHub hosts the primary git repository and other services like the bug tracker at https://github.com/curl/curl. Also again, some companies have sponsored certain parts of the development in the past and I hope some will continue to do so in the future. If you want to support our project, consider a donation or a banner-program or even better: by helping us with coding, documenting or testing etc. See also: https://curl.se/sponsors.html 1.7 What about CURL from curl.com? During the summer of 2001, curl.com was busy advertising their client-side programming language for the web, named CURL. We are in no way associated with curl.com or their CURL programming language. Our project name curl has been in effective use since 1998. We were not the first computer related project to use the name "curl" and do not claim any rights to the name. We recognize that we will be living in parallel with curl.com and wish them every success. 1.8 I have a problem, who do I mail? Please do not mail any single individual unless you really need to. Keep curl-related questions on a suitable mailing list. All available mailing lists are listed in the MANUAL document and online at https://curl.se/mail/ Keeping curl-related questions and discussions on mailing lists allows others to join in and help, to share their ideas, to contribute their suggestions and to spread their wisdom. Keeping discussions on public mailing lists also allows for others to learn from this (both current and future users thanks to the web based archives of the mailing lists), thus saving us from having to repeat ourselves even more. Thanks for respecting this. If you have found or simply suspect a security problem in curl or libcurl, submit all the details at https://hackerone.one/curl. On there we keep the issue private while we investigate, confirm it, work and validate a fix and agree on a time schedule for publication etc. That way we produce a fix in a timely manner before the flaw is announced to the world, reducing the impact the problem risks having on existing users. Security issues can also be taking to the curl security team by emailing security at curl.se (closed list of receivers, mails are not disclosed). 1.9 Where do I buy commercial support for curl? curl is fully open source. It means you can hire any skilled engineer to fix your curl-related problems. We list available alternatives on the curl website: https://curl.se/support.html 1.10 How many are using curl? It is impossible to tell. We do not know how many users that knowingly have installed and use curl. We do not know how many users that use curl without knowing that they are in fact using it. We do not know how many users that downloaded or installed curl and then never use it. In 2020, we estimate that curl runs in roughly ten billion installations world wide. 1.11 Why do you not update ca-bundle.crt In the cURL project we have decided not to attempt to keep this file updated (or even present) since deciding what to add to a ca cert bundle is an undertaking we have not been ready to accept, and the one we can get from Mozilla is perfectly fine so there is no need to duplicate that work. Today, with many services performed over HTTPS, every operating system should come with a default ca cert bundle that can be deemed somewhat trustworthy and that collection (if reasonably updated) should be deemed to be a lot better than a private curl version. If you want the most recent collection of ca certs that Mozilla Firefox uses, we recommend that you extract the collection yourself from Mozilla Firefox (by running 'make ca-bundle), or by using our online service setup for this purpose: https://curl.se/docs/caextract.html 1.12 I have a problem who, can I chat with? There is a bunch of friendly people hanging out in the #curl channel on the IRC network libera.chat. If you are polite and nice, chances are good that you can get -- or provide -- help instantly. 1.13 curl's ECCN number? The US government restricts exports of software that contains or uses cryptography. When doing so, the Export Control Classification Number (ECCN) is used to identify the level of export control etc. Apache Software Foundation gives a good explanation of ECCNs at https://www.apache.org/dev/crypto.html We believe curl's number might be ECCN 5D002, another possibility is 5D992. It seems necessary to write them (the authority that administers ECCN numbers), asking to confirm. Comprehensible explanations of the meaning of such numbers and how to obtain them (resp.) are here https://www.bis.doc.gov/licensing/exportingbasics.htm https://www.bis.doc.gov/licensing/do_i_needaneccn.html An incomprehensible description of the two numbers above is here https://www.bis.doc.gov/index.php/documents/new-encryption/1653-ccl5-pt2-3 1.14 How do I submit my patch? We strongly encourage you to submit changes and improvements directly as "pull requests" on GitHub: https://github.com/curl/curl/pulls If you for any reason cannot or will not deal with GitHub, send your patch to the curl-library mailing list. We are many subscribers there and there are lots of people who can review patches, comment on them and "receive" them properly. Lots of more details are found in the CONTRIBUTE.md and INTERNALS.md documents. 1.15 How do I port libcurl to my OS? Here's a rough step-by-step: 1. copy a suitable lib/config-*.h file as a start to lib/config-[youros].h 2. edit lib/config-[youros].h to match your OS and setup 3. edit lib/curl_setup.h to include config-[youros].h when your OS is detected by the preprocessor, in the style others already exist 4. compile lib/*.c and make them into a library 2. Install Related Problems 2.1 configure fails when using static libraries You may find that configure fails to properly detect the entire dependency chain of libraries when you provide static versions of the libraries that configure checks for. The reason why static libraries is much harder to deal with is that for them we do not get any help but the script itself must know or check what more libraries that are needed (with shared libraries, that dependency "chain" is handled automatically). This is a error-prone process and one that also tends to vary over time depending on the release versions of the involved components and may also differ between operating systems. For that reason, configure does few attempts to actually figure this out and you are instead encouraged to set LIBS and LDFLAGS accordingly when you invoke configure, and point out the needed libraries and set the necessary flags yourself. 2.2 Does curl work with other SSL libraries? curl has been written to use a generic SSL function layer internally, and that SSL functionality can then be provided by one out of many different SSL backends. curl can be built to use one of the following SSL alternatives: OpenSSL, libressl, BoringSSL, AWS-LC, GnuTLS, wolfSSL, mbedTLS, Secure Transport (native iOS/OS X), Schannel (native Windows), BearSSL or Rustls. They all have their pros and cons, and we try to maintain a comparison of them here: https://curl.se/docs/ssl-compared.html 2.3 How do I upgrade curl.exe in Windows? The curl tool that is shipped as an integrated component of Windows 10 and Windows 11 is managed by Microsoft. If you were to delete the file or replace it with a newer version downloaded from https://curl.se/windows, then Windows Update will cease to work on your system. There is no way to independently force an upgrade of the curl.exe that is part of Windows other than through the regular Windows update process. There is also nothing the curl project itself can do about this, since this is managed and controlled entirely by Microsoft as owners of the operating system. You can always download and install the latest version of curl for Windows from https://curl.se/windows into a separate location. 2.4 Does curl support SOCKS (RFC 1928) ? Yes, SOCKS 4 and 5 are supported. 3. Usage problems 3.1 curl: (1) SSL is disabled, https: not supported If you get this output when trying to get anything from an HTTPS server, it means that the instance of curl/libcurl that you are using was built without support for this protocol. This could have happened if the configure script that was run at build time could not find all libs and include files curl requires for SSL to work. If the configure script fails to find them, curl is simply built without SSL support. To get HTTPS support into a curl that was previously built but that reports that HTTPS is not supported, you should dig through the document and logs and check out why the configure script does not find the SSL libs and/or include files. Also, check out the other paragraph in this FAQ labeled "configure does not find OpenSSL even when it is installed". 3.2 How do I tell curl to resume a transfer? curl supports resumed transfers both ways on both FTP and HTTP. Try the -C option. 3.3 Why does my posting using -F not work? You cannot arbitrarily use -F or -d, the choice between -F or -d depends on the HTTP operation you need curl to do and what the web server that will receive your post expects. If the form you are trying to submit uses the type 'multipart/form-data', then and only then you must use the -F type. In all the most common cases, you should use -d which then causes a posting with the type 'application/x-www-form-urlencoded'. This is described in some detail in the MANUAL and TheArtOfHttpScripting documents, and if you do not understand it the first time, read it again before you post questions about this to the mailing list. Also, try reading through the mailing list archives for old postings and questions regarding this. 3.4 How do I tell curl to run custom FTP commands? You can tell curl to perform optional commands both before and/or after a file transfer. Study the -Q/--quote option. Since curl is used for file transfers, you do not normally use curl to perform FTP commands without transferring anything. Therefore you must always specify a URL to transfer to/from even when doing custom FTP commands, or use -I which implies the "no body" option sent to libcurl. 3.5 How can I disable the Accept: */* header? You can change all internally generated headers by adding a replacement with the -H/--header option. By adding a header with empty contents you safely disable that one. Use -H "Accept:" to disable that specific header. 3.6 Does curl support ASP, XML, XHTML or HTML version Y? To curl, all contents are alike. It does not matter how the page was generated. It may be ASP, PHP, Perl, shell-script, SSI or plain HTML files. There is no difference to curl and it does not even know what kind of language that generated the page. See also item 3.14 regarding JavaScript. 3.7 Can I use curl to delete/rename a file through FTP? Yes. You specify custom FTP commands with -Q/--quote. One example would be to delete a file after you have downloaded it: curl -O ftp://example.com/coolfile -Q '-DELE coolfile' or rename a file after upload: curl -T infile ftp://example.com/dir/ -Q "-RNFR infile" -Q "-RNTO newname" 3.8 How do I tell curl to follow HTTP redirects? curl does not follow so-called redirects by default. The Location: header that informs the client about this is only interpreted if you are using the -L/--location option. As in: curl -L http://example.com Not all redirects are HTTP ones, see 4.14 3.9 How do I use curl in my favorite programming language? Many programming languages have interfaces/bindings that allow you to use curl without having to use the command line tool. If you are fluent in such a language, you may prefer to use one of these interfaces instead. Find out more about which languages that support curl directly, and how to install and use them, in the libcurl section of the curl website: https://curl.se/libcurl/ All the various bindings to libcurl are made by other projects and people, outside of the cURL project. The cURL project itself only produces libcurl with its plain C API. If you do not find anywhere else to ask you can ask about bindings on the curl-library list too, but be prepared that people on that list may not know anything about bindings. In December 2021, there were interfaces available for the following languages: Ada95, Basic, C, C++, Ch, Cocoa, D, Delphi, Dylan, Eiffel, Euphoria, Falcon, Ferite, Gambas, glib/GTK+, Go, Guile, Harbour, Haskell, Java, Julia, Lisp, Lua, Mono, .NET, node.js, Object-Pascal, OCaml, Pascal, Perl, PHP, PostgreSQL, Python, R, Rexx, Ring, RPG, Ruby, Rust, Scheme, Scilab, S-Lang, Smalltalk, SP-Forth, SPL, Tcl, Visual Basic, Visual FoxPro, Q, wxwidgets, XBLite and Xoho. By the time you read this, additional ones may have appeared. 3.10 What about SOAP, WebDAV, XML-RPC or similar protocols over HTTP? curl adheres to the HTTP spec, which basically means you can play with *any* protocol that is built on top of HTTP. Protocols such as SOAP, WEBDAV and XML-RPC are all such ones. You can use -X to set custom requests and -H to set custom headers (or replace internally generated ones). Using libcurl is of course just as good and you would just use the proper library options to do the same. 3.11 How do I POST with a different Content-Type? You can always replace the internally generated headers with -H/--header. To make a simple HTTP POST with text/xml as content-type, do something like: curl -d "datatopost" -H "Content-Type: text/xml" [URL] 3.12 Why do FTP-specific features over HTTP proxy fail? Because when you use an HTTP proxy, the protocol spoken on the network will be HTTP, even if you specify an FTP URL. This effectively means that you normally cannot use FTP-specific features such as FTP upload and FTP quote etc. There is one exception to this rule, and that is if you can "tunnel through" the given HTTP proxy. Proxy tunneling is enabled with a special option (-p) and is generally not available as proxy admins usually disable tunneling to ports other than 443 (which is used for HTTPS access through proxies). 3.13 Why do my single/double quotes fail? To specify a command line option that includes spaces, you might need to put the entire option within quotes. Like in: curl -d " with spaces " example.com or perhaps curl -d ' with spaces ' example.com Exactly what kind of quotes and how to do this is entirely up to the shell or command line interpreter that you are using. For most unix shells, you can more or less pick either single (') or double (") quotes. For Windows/DOS command prompts you must use double (") quotes, and if the option string contains inner double quotes you can escape them with a backslash. For Windows powershell the arguments are not always passed on as expected because curl is not a powershell script. You may or may not be able to use single quotes. To escape inner double quotes seems to require a backslash-backtick escape sequence and the outer quotes as double quotes. Please study the documentation for your particular environment. Examples in the curl docs will use a mix of both of these as shown above. You must adjust them to work in your environment. Remember that curl works and runs on more operating systems than most single individuals have ever tried. 3.14 Does curl support JavaScript or PAC (automated proxy config)? Many web pages do magic stuff using embedded JavaScript. curl and libcurl have no built-in support for that, so it will be treated just like any other contents. .pac files are a Netscape invention and are sometimes used by organizations to allow them to differentiate which proxies to use. The .pac contents is just a JavaScript program that gets invoked by the browser and that returns the name of the proxy to connect to. Since curl does not support JavaScript, it cannot support .pac proxy configuration either. Some workarounds usually suggested to overcome this JavaScript dependency: Depending on the JavaScript complexity, write up a script that translates it to another language and execute that. Read the JavaScript code and rewrite the same logic in another language. Implement a JavaScript interpreter, people have successfully used the Mozilla JavaScript engine in the past. Ask your admins to stop this, for a static proxy setup or similar. 3.15 Can I do recursive fetches with curl? No. curl itself has no code that performs recursive operations, such as those performed by wget and similar tools. There exists wrapper scripts with that functionality (for example the curlmirror perl script), and you can write programs based on libcurl to do it, but the command line tool curl itself cannot. 3.16 What certificates do I need when I use SSL? There are three different kinds of "certificates" to keep track of when we talk about using SSL-based protocols (HTTPS or FTPS) using curl or libcurl. CLIENT CERTIFICATE The server you communicate with may require that you can provide this in order to prove that you actually are who you claim to be. If the server does not require this, you do not need a client certificate. A client certificate is always used together with a private key, and the private key has a pass phrase that protects it. SERVER CERTIFICATE The server you communicate with has a server certificate. You can and should verify this certificate to make sure that you are truly talking to the real server and not a server impersonating it. CERTIFICATE AUTHORITY CERTIFICATE ("CA cert") You often have several CA certs in a CA cert bundle that can be used to verify a server certificate that was signed by one of the authorities in the bundle. curl does not come with a CA cert bundle but most curl installs provide one. You can also override the default. The server certificate verification process is made by using a Certificate Authority certificate ("CA cert") that was used to sign the server certificate. Server certificate verification is enabled by default in curl and libcurl and is often the reason for problems as explained in FAQ entry 4.12 and the SSLCERTS document (https://curl.se/docs/sslcerts.html). Server certificates that are "self-signed" or otherwise signed by a CA that you do not have a CA cert for, cannot be verified. If the verification during a connect fails, you are refused access. You then need to explicitly disable the verification to connect to the server. 3.17 How do I list the root directory of an FTP server? There are two ways. The way defined in the RFC is to use an encoded slash in the first path part. List the "/tmp" directory like this: curl ftp://ftp.example.com/%2ftmp/ or the not-quite-kosher-but-more-readable way, by simply starting the path section of the URL with a slash: curl ftp://ftp.example.com//tmp/ 3.18 Can I use curl to send a POST/PUT and not wait for a response? No. You can easily write your own program using libcurl to do such stunts. 3.19 How do I get HTTP from a host using a specific IP address? For example, you may be trying out a website installation that is not yet in the DNS. Or you have a site using multiple IP addresses for a given host name and you want to address a specific one out of the set. Set a custom Host: header that identifies the server name you want to reach but use the target IP address in the URL: curl --header "Host: www.example.com" http://127.0.0.1/ You can also opt to add faked host name entries to curl with the --resolve option. That has the added benefit that things like redirects will also work properly. The above operation would instead be done as: curl --resolve www.example.com:80:127.0.0.1 http://www.example.com/ 3.20 How to SFTP from my user's home directory? Contrary to how FTP works, SFTP and SCP URLs specify the exact directory to work with. It means that if you do not specify that you want the user's home directory, you get the actual root directory. To specify a file in your user's home directory, you need to use the correct URL syntax which for SFTP might look similar to: curl -O -u user:password sftp://example.com/~/file.txt and for SCP it is just a different protocol prefix: curl -O -u user:password scp://example.com/~/file.txt 3.21 Protocol xxx not supported or disabled in libcurl When passing on a URL to curl to use, it may respond that the particular protocol is not supported or disabled. The particular way this error message is phrased is because curl does not make a distinction internally of whether a particular protocol is not supported (i.e. never got any code added that knows how to speak that protocol) or if it was explicitly disabled. curl can be built to only support a given set of protocols, and the rest would then be disabled or not supported. Note that this error will also occur if you pass a wrongly spelled protocol part as in "htpt://example.com" or as in the less evident case if you prefix the protocol part with a space as in " http://example.com/". 3.22 curl -X gives me HTTP problems In normal circumstances, -X should hardly ever be used. By default you use curl without explicitly saying which request method to use when the URL identifies an HTTP transfer. If you just pass in a URL like "curl http://example.com" it will use GET. If you use -d or -F curl will use POST, -I will cause a HEAD and -T will make it a PUT. If for whatever reason you are not happy with these default choices that curl does for you, you can override those request methods by specifying -X [WHATEVER]. This way you can for example send a DELETE by doing "curl -X DELETE [URL]". It is thus pointless to do "curl -XGET [URL]" as GET would be used anyway. In the same vein it is pointless to do "curl -X POST -d data [URL]"... But you can make a fun and somewhat rare request that sends a request-body in a GET request with something like "curl -X GET -d data [URL]" Note that -X does not actually change curl's behavior as it only modifies the actual string sent in the request, but that may of course trigger a different set of events. Accordingly, by using -XPOST on a command line that for example would follow a 303 redirect, you will effectively prevent curl from behaving correctly. Be aware. 4. Running Problems 4.2 Why do I get problems when I use & or % in the URL? In general Unix shells, the & symbol is treated specially and when used, it runs the specified command in the background. To safely send the & as a part of a URL, you should quote the entire URL by using single (') or double (") quotes around it. Similar problems can also occur on some shells with other characters, including ?*!$~(){}<>\|;`. When in doubt, quote the URL. An example that would invoke a remote CGI that uses &-symbols could be: curl 'http://www.example.com/cgi-bin/query?text=yes&q=curl' In Windows, the standard DOS shell treats the percent sign specially and you need to use TWO percent signs for each single one you want to use in the URL. If you want a literal percent sign to be part of the data you pass in a POST using -d/--data you must encode it as '%25' (which then also needs the percent sign doubled on Windows machines). 4.3 How can I use {, }, [ or ] to specify multiple URLs? Because those letters have a special meaning to the shell, to be used in a URL specified to curl you must quote them. An example that downloads two URLs (sequentially) would be: curl '{curl,www}.haxx.se' To be able to use those characters as actual parts of the URL (without using them for the curl URL "globbing" system), use the -g/--globoff option: curl -g 'www.example.com/weirdname[].html' 4.4 Why do I get downloaded data even though the web page does not exist? curl asks remote servers for the page you specify. If the page does not exist at the server, the HTTP protocol defines how the server should respond and that means that headers and a "page" will be returned. That is simply how HTTP works. By using the --fail option you can tell curl explicitly to not get any data if the HTTP return code does not say success. 4.5 Why do I get return code XXX from an HTTP server? RFC 2616 clearly explains the return codes. This is a short transcript. Go read the RFC for exact details: 4.5.1 "400 Bad Request" The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications. 4.5.2 "401 Unauthorized" The request requires user authentication. 4.5.3 "403 Forbidden" The server understood the request, but is refusing to fulfill it. Authorization will not help and the request SHOULD NOT be repeated. 4.5.4 "404 Not Found" The server has not found anything matching the Request-URI. No indication is given as to whether the condition is temporary or permanent. 4.5.5 "405 Method Not Allowed" The method specified in the Request-Line is not allowed for the resource identified by the Request-URI. The response MUST include an Allow header containing a list of valid methods for the requested resource. 4.5.6 "301 Moved Permanently" If you get this return code and an HTML output similar to this:

Moved Permanently

The document has moved here. it might be because you requested a directory URL but without the trailing slash. Try the same operation again _with_ the trailing URL, or use the -L/--location option to follow the redirection. 4.6 Can you tell me what error code 142 means? All curl error codes are described at the end of the man page, in the section called "EXIT CODES". Error codes that are larger than the highest documented error code means that curl has exited due to a crash. This is a serious error, and we appreciate a detailed bug report from you that describes how we could go ahead and repeat this. 4.7 How do I keep user names and passwords secret in curl command lines? This problem has two sides: The first part is to avoid having clear-text passwords in the command line so that they do not appear in 'ps' outputs and similar. That is easily avoided by using the "-K" option to tell curl to read parameters from a file or stdin to which you can pass the secret info. curl itself will also attempt to "hide" the given password by blanking out the option - this does not work on all platforms. To keep the passwords in your account secret from the rest of the world is not a task that curl addresses. You could of course encrypt them somehow to at least hide them from being read by human eyes, but that is not what anyone would call security. Also note that regular HTTP (using Basic authentication) and FTP passwords are sent as cleartext across the network. All it takes for anyone to fetch them is to listen on the network. Eavesdropping is easy. Use more secure authentication methods (like Digest, Negotiate or even NTLM) or consider the SSL-based alternatives HTTPS and FTPS. 4.8 I found a bug It is not a bug if the behavior is documented. Read the docs first. Especially check out the KNOWN_BUGS file, it may be a documented bug. If it is a problem with a binary you have downloaded or a package for your particular platform, try contacting the person who built the package/archive you have. If there is a bug, read the BUGS document first. Then report it as described in there. 4.9 curl cannot authenticate to a server that requires NTLM? NTLM support requires OpenSSL, GnuTLS, mbedTLS, Secure Transport, or Microsoft Windows libraries at build-time to provide this functionality. 4.10 My HTTP request using HEAD, PUT or DELETE does not work Many web servers allow or demand that the administrator configures the server properly for these requests to work on the web server. Some servers seem to support HEAD only on certain kinds of URLs. To fully grasp this, try the documentation for the particular server software you are trying to interact with. This is not anything curl can do anything about. 4.11 Why do my HTTP range requests return the full document? Because the range may not be supported by the server, or the server may choose to ignore it and return the full document anyway. 4.12 Why do I get "certificate verify failed" ? When you invoke curl and get an error 60 error back it means that curl could not verify that the server's certificate was good. curl verifies the certificate using the CA cert bundle and verifying for which names the certificate has been granted. To completely disable the certificate verification, use -k. This does however enable man-in-the-middle attacks and makes the transfer INSECURE. We strongly advise against doing this for more than experiments. If you get this failure with a CA cert bundle installed and used, the server's certificate might not be signed by one of the CA's in your CA store. It might for example be self-signed. You then correct this problem by obtaining a valid CA cert for the server. Or again, decrease the security by disabling this check. At times, you find that the verification works in your favorite browser but fails in curl. When this happens, the reason is usually that the server sends an incomplete cert chain. The server is mandated to send all "intermediate certificates" but does not. This typically works with browsers anyway since they A) cache such certs and B) supports AIA which downloads such missing certificates on demand. This is a server misconfiguration. A good way to figure out if this is the case it to use the SSL Labs server test and check the certificate chain: https://www.ssllabs.com/ssltest/ Details are also in the SSLCERTS.md document, found online here: https://curl.se/docs/sslcerts.html 4.13 Why is curl -R on Windows one hour off? Since curl 7.53.0 this issue should be fixed as long as curl was built with any modern compiler that allows for a 64-bit curl_off_t type. For older compilers or prior curl versions it may set a time that appears one hour off. This happens due to a flaw in how Windows stores and uses file modification times and it is not easily worked around. For more details read this: https://www.codeproject.com/Articles/1144/Beating-the-Daylight-Savings-Time-bug-and-getting 4.14 Redirects work in browser but not with curl curl supports HTTP redirects well (see item 3.8). Browsers generally support at least two other ways to perform redirects that curl does not: Meta tags. You can write an HTML tag that will cause the browser to redirect to another given URL after a certain time. JavaScript. You can write a JavaScript program embedded in an HTML page that redirects the browser to another given URL. There is no way to make curl follow these redirects. You must either manually figure out what the page is set to do, or write a script that parses the results and fetches the new URL. 4.15 FTPS does not work curl supports FTPS (sometimes known as FTP-SSL) both implicit and explicit mode. When a URL is used that starts with FTPS://, curl assumes implicit SSL on the control connection and will therefore immediately connect and try to speak SSL. FTPS:// connections default to port 990. To use explicit FTPS, you use an FTP:// URL and the --ftp-ssl option (or one of its related flavors). This is the most common method, and the one mandated by RFC 4217. This kind of connection will then of course use the standard FTP port 21 by default. 4.16 My HTTP POST or PUT requests are slow libcurl makes all POST and PUT requests (except for requests with a small request body) use the "Expect: 100-continue" header. This header allows the server to deny the operation early so that libcurl can bail out before having to send any data. This is useful in authentication cases and others. However, many servers do not implement the Expect: stuff properly and if the server does not respond (positively) within 1 second libcurl will continue and send off the data anyway. You can disable libcurl's use of the Expect: header the same way you disable any header, using -H / CURLOPT_HTTPHEADER, or by forcing it to use HTTP 1.0. 4.17 Non-functional connect timeouts In most Windows setups having a timeout longer than 21 seconds make no difference, as it will only send 3 TCP SYN packets and no more. The second packet sent three seconds after the first and the third six seconds after the second. No more than three packets are sent, no matter how long the timeout is set. See option TcpMaxConnectRetransmissions on this page: https://support.microsoft.com/en-us/kb/175523/en-us Also, even on non-Windows systems there may run a firewall or anti-virus software or similar that accepts the connection but does not actually do anything else. This will make (lib)curl to consider the connection connected and thus the connect timeout will not trigger. 4.18 file:// URLs containing drive letters (Windows, NetWare) When using curl to try to download a local file, one might use a URL in this format: file://D:/blah.txt you will find that even if D:\blah.txt does exist, curl returns a 'file not found' error. According to RFC 1738 (https://www.ietf.org/rfc/rfc1738.txt), file:// URLs must contain a host component, but it is ignored by most implementations. In the above example, 'D:' is treated as the host component, and is taken away. Thus, curl tries to open '/blah.txt'. If your system is installed to drive C:, that will resolve to 'C:\blah.txt', and if that does not exist you will get the not found error. To fix this problem, use file:// URLs with *three* leading slashes: file:///D:/blah.txt Alternatively, if it makes more sense, specify 'localhost' as the host component: file://localhost/D:/blah.txt In either case, curl should now be looking for the correct file. 4.19 Why does not curl return an error when the network cable is unplugged? Unplugging a cable is not an error situation. The TCP/IP protocol stack was designed to be fault tolerant, so even though there may be a physical break somewhere the connection should not be affected, just possibly delayed. Eventually, the physical break will be fixed or the data will be re-routed around the physical problem through another path. In such cases, the TCP/IP stack is responsible for detecting when the network connection is irrevocably lost. Since with some protocols it is perfectly legal for the client to wait indefinitely for data, the stack may never report a problem, and even when it does, it can take up to 20 minutes for it to detect an issue. The curl option --keepalive-time enables keep-alive support in the TCP/IP stack which makes it periodically probe the connection to make sure it is still available to send data. That should reliably detect any TCP/IP network failure. TCP keep alive will not detect the network going down before the TCP/IP connection is established (e.g. during a DNS lookup) or using protocols that do not use TCP. To handle those situations, curl offers a number of timeouts on its own. --speed-limit/--speed-time will abort if the data transfer rate falls too low, and --connect-timeout and --max-time can be used to put an overall timeout on the connection phase or the entire transfer. A libcurl-using application running in a known physical environment (e.g. an embedded device with only a single network connection) may want to act immediately if its lone network connection goes down. That can be achieved by having the application monitor the network connection on its own using an OS-specific mechanism, then signaling libcurl to abort (see also item 5.13). 4.20 curl does not return error for HTTP non-200 responses Correct. Unless you use -f (--fail). When doing HTTP transfers, curl will perform exactly what you are asking it to do and if successful it will not return an error. You can use curl to test your web server's "file not found" page (that gets 404 back), you can use it to check your authentication protected web pages (that gets a 401 back) and so on. The specific HTTP response code does not constitute a problem or error for curl. It simply sends and delivers HTTP as you asked and if that worked, everything is fine and dandy. The response code is generally providing more higher level error information that curl does not care about. The error was not in the HTTP transfer. If you want your command line to treat error codes in the 400 and up range as errors and thus return a non-zero value and possibly show an error message, curl has a dedicated option for that: -f (CURLOPT_FAILONERROR in libcurl speak). You can also use the -w option and the variable %{response_code} to extract the exact response code that was returned in the response. 5. libcurl Issues 5.1 Is libcurl thread-safe? Yes. We have written the libcurl code specifically adjusted for multi-threaded programs. libcurl will use thread-safe functions instead of non-safe ones if your system has such. Note that you must never share the same handle in multiple threads. There may be some exceptions to thread safety depending on how libcurl was built. Please review the guidelines for thread safety to learn more: https://curl.se/libcurl/c/threadsafe.html 5.2 How can I receive all data into a large memory chunk? [ See also the examples/getinmemory.c source ] You are in full control of the callback function that gets called every time there is data received from the remote server. You can make that callback do whatever you want. You do not have to write the received data to a file. One solution to this problem could be to have a pointer to a struct that you pass to the callback function. You set the pointer using the CURLOPT_WRITEDATA option. Then that pointer will be passed to the callback instead of a FILE * to a file: /* imaginary struct */ struct MemoryStruct { char *memory; size_t size; }; /* imaginary callback function */ size_t WriteMemoryCallback(void *ptr, size_t size, size_t nmemb, void *data) { size_t realsize = size * nmemb; struct MemoryStruct *mem = (struct MemoryStruct *)data; mem->memory = (char *)realloc(mem->memory, mem->size + realsize + 1); if (mem->memory) { memcpy(&(mem->memory[mem->size]), ptr, realsize); mem->size += realsize; mem->memory[mem->size] = 0; } return realsize; } 5.3 How do I fetch multiple files with libcurl? libcurl has excellent support for transferring multiple files. You should just repeatedly set new URLs with curl_easy_setopt() and then transfer it with curl_easy_perform(). The handle you get from curl_easy_init() is not only reusable, but you are even encouraged to reuse it if you can, as that will enable libcurl to use persistent connections. 5.4 Does libcurl do Winsock initialization on win32 systems? Yes, if told to in the curl_global_init() call. 5.5 Does CURLOPT_WRITEDATA and CURLOPT_READDATA work on win32 ? Yes, but you cannot open a FILE * and pass the pointer to a DLL and have that DLL use the FILE * (as the DLL and the client application cannot access each others' variable memory areas). If you set CURLOPT_WRITEDATA you must also use CURLOPT_WRITEFUNCTION as well to set a function that writes the file, even if that simply writes the data to the specified FILE *. Similarly, if you use CURLOPT_READDATA you must also specify CURLOPT_READFUNCTION. 5.6 What about Keep-Alive or persistent connections? curl and libcurl have excellent support for persistent connections when transferring several files from the same server. curl will attempt to reuse connections for all URLs specified on the same command line/config file, and libcurl will reuse connections for all transfers that are made using the same libcurl handle. When you use the easy interface the connection cache is kept within the easy handle. If you instead use the multi interface, the connection cache will be kept within the multi handle and will be shared among all the easy handles that are used within the same multi handle. 5.7 Link errors when building libcurl on Windows You need to make sure that your project, and all the libraries (both static and dynamic) that it links against, are compiled/linked against the same run time library. This is determined by the /MD, /ML, /MT (and their corresponding /M?d) options to the command line compiler. /MD (linking against MSVCRT dll) seems to be the most commonly used option. When building an application that uses the static libcurl library, you must add -DCURL_STATICLIB to your CFLAGS. Otherwise the linker will look for dynamic import symbols. If you are using Visual Studio, you need to instead add CURL_STATICLIB in the "Preprocessor Definitions" section. If you get a linker error like "unknown symbol __imp__curl_easy_init ..." you have linked against the wrong (static) library. If you want to use the libcurl.dll and import lib, you do not need any extra CFLAGS, but use one of the import libraries below. These are the libraries produced by the various lib/Makefile.* files: Target: static lib. import lib for libcurl*.dll. ----------------------------------------------------------- MinGW: libcurl.a libcurldll.a MSVC (release): libcurl.lib libcurl_imp.lib MSVC (debug): libcurld.lib libcurld_imp.lib Borland: libcurl.lib libcurl_imp.lib 5.8 libcurl.so.X: open failed: No such file or directory This is an error message you might get when you try to run a program linked with a shared version of libcurl and your runtime linker (ld.so) could not find the shared library named libcurl.so.X. (Where X is the number of the current libcurl ABI, typically 3 or 4). You need to make sure that ld.so finds libcurl.so.X. You can do that multiple ways, and it differs somewhat between different operating systems. They are usually: * Add an option to the linker command line that specify the hard-coded path the runtime linker should check for the lib (usually -R) * Set an environment variable (LD_LIBRARY_PATH for example) where ld.so should check for libs * Adjust the system's config to check for libs in the directory where you have put the library (like Linux's /etc/ld.so.conf) 'man ld.so' and 'man ld' will tell you more details 5.9 How does libcurl resolve host names? libcurl supports a large number of name resolve functions. One of them is picked at build-time and will be used unconditionally. Thus, if you want to change name resolver function you must rebuild libcurl and tell it to use a different function. - The non-IPv6 resolver that can use one of four different host name resolve calls (depending on what your system supports): A - gethostbyname() B - gethostbyname_r() with 3 arguments C - gethostbyname_r() with 5 arguments D - gethostbyname_r() with 6 arguments - The IPv6-resolver that uses getaddrinfo() - The c-ares based name resolver that uses the c-ares library for resolves. Using this offers asynchronous name resolves. - The threaded resolver (default option on Windows). It uses: A - gethostbyname() on plain IPv4 hosts B - getaddrinfo() on IPv6 enabled hosts Also note that libcurl never resolves or reverse-lookups addresses given as pure numbers, such as 127.0.0.1 or ::1. 5.10 How do I prevent libcurl from writing the response to stdout? libcurl provides a default built-in write function that writes received data to stdout. Set the CURLOPT_WRITEFUNCTION to receive the data, or possibly set CURLOPT_WRITEDATA to a different FILE * handle. 5.11 How do I make libcurl not receive the whole HTTP response? You make the write callback (or progress callback) return an error and libcurl will then abort the transfer. 5.12 Can I make libcurl fake or hide my real IP address? No. libcurl operates on a higher level. Besides, faking IP address would imply sending IP packets with a made-up source address, and then you normally get a problem with receiving the packet sent back as they would then not be routed to you. If you use a proxy to access remote sites, the sites will not see your local IP address but instead the address of the proxy. Also note that on many networks NATs or other IP-munging techniques are used that makes you see and use a different IP address locally than what the remote server will see you coming from. You may also consider using https://www.torproject.org/ . 5.13 How do I stop an ongoing transfer? With the easy interface you make sure to return the correct error code from one of the callbacks, but none of them are instant. There is no function you can call from another thread or similar that will stop it immediately. Instead, you need to make sure that one of the callbacks you use returns an appropriate value that will stop the transfer. Suitable callbacks that you can do this with include the progress callback, the read callback and the write callback. If you are using the multi interface, you can also stop a transfer by removing the particular easy handle from the multi stack at any moment you think the transfer is done or when you wish to abort the transfer. 5.14 Using C++ non-static functions for callbacks? libcurl is a C library, it does not know anything about C++ member functions. You can overcome this "limitation" with relative ease using a static member function that is passed a pointer to the class: // f is the pointer to your object. static size_t YourClass::func(void *buffer, size_t sz, size_t n, void *f) { // Call non-static member function. static_cast(f)->nonStaticFunction(); } // This is how you pass pointer to the static function: curl_easy_setopt(hcurl, CURLOPT_WRITEFUNCTION, YourClass::func); curl_easy_setopt(hcurl, CURLOPT_WRITEDATA, this); 5.15 How do I get an FTP directory listing? If you end the FTP URL you request with a slash, libcurl will provide you with a directory listing of that given directory. You can also set CURLOPT_CUSTOMREQUEST to alter what exact listing command libcurl would use to list the files. The follow-up question tends to be how is a program supposed to parse the directory listing. How does it know what's a file and what's a directory and what's a symlink etc. If the FTP server supports the MLSD command then it will return data in a machine-readable format that can be parsed for type. The types are specified by RFC 3659 section 7.5.1. If MLSD is not supported then you have to work with what you are given. The LIST output format is entirely at the server's own liking and the NLST output does not reveal any types and in many cases does not even include all the directory entries. Also, both LIST and NLST tend to hide unix-style hidden files (those that start with a dot) by default so you need to do "LIST -a" or similar to see them. Example - List only directories. ftp.funet.fi supports MLSD and ftp.kernel.org does not: curl -s ftp.funet.fi/pub/ -X MLSD | \ perl -lne 'print if s/(?:^|;)type=dir;[^ ]+ (.+)$/$1/' curl -s ftp.kernel.org/pub/linux/kernel/ | \ perl -lne 'print if s/^d[-rwx]{9}(?: +[^ ]+){7} (.+)$/$1/' If you need to parse LIST output in libcurl one such existing list parser is available at https://cr.yp.to/ftpparse.html Versions of libcurl since 7.21.0 also provide the ability to specify a wildcard to download multiple files from one FTP directory. 5.16 I want a different time-out Sometimes users realize that CURLOPT_TIMEOUT and CURLOPT_CONNECTIMEOUT are not sufficiently advanced or flexible to cover all the various use cases and scenarios applications end up with. libcurl offers many more ways to time-out operations. A common alternative is to use the CURLOPT_LOW_SPEED_LIMIT and CURLOPT_LOW_SPEED_TIME options to specify the lowest possible speed to accept before to consider the transfer timed out. The most flexible way is by writing your own time-out logic and using CURLOPT_XFERINFOFUNCTION (perhaps in combination with other callbacks) and use that to figure out exactly when the right condition is met when the transfer should get stopped. 5.17 Can I write a server with libcurl? No. libcurl offers no functions or building blocks to build any kind of Internet protocol server. libcurl is only a client-side library. For server libraries, you need to continue your search elsewhere but there exist many good open source ones out there for most protocols you could want a server for. There are also really good stand-alone servers that have been tested and proven for many years. There is no need for you to reinvent them. 5.18 Does libcurl use threads? Put simply: no, libcurl will execute in the same thread you call it in. All callbacks will be called in the same thread as the one you call libcurl in. If you want to avoid your thread to be blocked by the libcurl call, you make sure you use the non-blocking multi API which will do transfers asynchronously - still in the same single thread. libcurl will potentially internally use threads for name resolving, if it was built to work like that, but in those cases it will create the child threads by itself and they will only be used and then killed internally by libcurl and never exposed to the outside. 6. License Issues curl and libcurl are released under a MIT/X derivative license. The license is liberal and should not impose a problem for your project. This section is just a brief summary for the cases we get the most questions. (Parts of this section was much enhanced by Bjorn Reese.) We are not lawyers and this is not legal advice. You should probably consult one if you want true and accurate legal insights without our prejudice. Note especially that this section concerns the libcurl license only; compiling in features of libcurl that depend on other libraries (e.g. OpenSSL) may affect the licensing obligations of your application. 6.1 I have a GPL program, can I use the libcurl library? Yes Since libcurl may be distributed under the MIT/X derivative license, it can be used together with GPL in any software. 6.2 I have a closed-source program, can I use the libcurl library? Yes libcurl does not put any restrictions on the program that uses the library. 6.3 I have a BSD licensed program, can I use the libcurl library? Yes libcurl does not put any restrictions on the program that uses the library. 6.4 I have a program that uses LGPL libraries, can I use libcurl? Yes The LGPL license does not clash with other licenses. 6.5 Can I modify curl/libcurl for my program and keep the changes secret? Yes The MIT/X derivative license practically allows you to do almost anything with the sources, on the condition that the copyright texts in the sources are left intact. 6.6 Can you please change the curl/libcurl license to XXXX? No. We have carefully picked this license after years of development and discussions and a large amount of people have contributed with source code knowing that this is the license we use. This license puts the restrictions we want on curl/libcurl and it does not spread to other programs or libraries that use it. It should be possible for everyone to use libcurl or curl in their projects, no matter what license they already have in use. 6.7 What are my obligations when using libcurl in my commercial apps? Next to none. All you need to adhere to is the MIT-style license (stated in the COPYING file) which basically says you have to include the copyright notice in "all copies" and that you may not use the copyright holder's name when promoting your software. You do not have to release any of your source code. You do not have to reveal or make public any changes to the libcurl source code. You do not have to broadcast to the world that you are using libcurl within your app. All we ask is that you disclose "the copyright notice and this permission notice" somewhere. Most probably like in the documentation or in the section where other third party dependencies already are mentioned and acknowledged. As can be seen here: https://curl.se/docs/companies.html and elsewhere, more and more companies are discovering the power of libcurl and take advantage of it even in commercial environments. 7. PHP/CURL Issues 7.1 What is PHP/CURL? The module for PHP that makes it possible for PHP programs to access curl- functions from within PHP. In the cURL project we call this module PHP/CURL to differentiate it from curl the command line tool and libcurl the library. The PHP team however does not refer to it like this (for unknown reasons). They call it plain CURL (often using all caps) or sometimes ext/curl, but both cause much confusion to users which in turn gives us a higher question load. 7.2 Who wrote PHP/CURL? PHP/CURL was initially written by Sterling Hughes. 7.3 Can I perform multiple requests using the same handle? Yes - at least in PHP version 4.3.8 and later (this has been known to not work in earlier versions, but the exact version when it started to work is unknown to me). After a transfer, you just set new options in the handle and make another transfer. This will make libcurl reuse the same connection if it can. 7.4 Does PHP/CURL have dependencies? PHP/CURL is a module that comes with the regular PHP package. It depends on and uses libcurl, so you need to have libcurl installed properly before PHP/CURL can be used. 8. Development 8.1 Why does curl use C89? As with everything in curl, there is a history and we keep using what we have used before until someone brings up the subject and argues for and works on changing it. We started out using C89 in the 1990s because that was the only way to write a truly portable C program and have it run as widely as possible. C89 was for a long time even necessary to make things work on otherwise considered modern platforms such as Windows. Today, we do not really know how many users that still require the use of a C89 compiler. We will continue to use C89 for as long as nobody brings up a strong enough reason for us to change our minds. The core developers of the project do not feel restricted by this and we are not convinced that going C99 will offer us enough of a benefit to warrant the risk of cutting off a share of users. 8.2 Will curl be rewritten? In one go: no. Little by little over time? Maybe. Over the years, new languages and clever operating environments come and go. Every now and then the urge apparently arises to request that we rewrite curl in another language. Some the most important properties in curl are maintaining the API and ABI for libcurl and keeping the behavior for the command line tool. As long as we can do that, everything else is up for discussion. To maintain the ABI, we probably have to maintain a certain amount of code in C, and to remain rock stable, we will never risk anything by rewriting a lot of things in one go. That said, we can certainly offer more and more optional backends written in other languages, as long as those backends can be plugged in at build-time. Backends can be written in any language, but should probably provide APIs usable from C to ease integration and transition.
