On Windows this requires Perl 5.22 from year 2015.
Also:
- mdlinkcheck: delete redundant error handling logic.
Follow-up to 77be4a7ab2#19437Closes#19461
To make it simpler to move them around, create and delete them without
syncing with `REUSE.toml`.
Also:
- checksrc: allow empty lines in `.checksrc`.
- comment on why curl printfs are disallowed in examples.
Closes#19024
Add infrastructure to colled and dispatch notifications for transfers
and the multi handle in general. Applications can register a callback
and en-/disable notification type the are interested in.
Without a callback installed, notifications are not collected. Same when
a notification type has not been enabled.
Memory allocation failures on adding notifications lead to a general
multi failure state and result in CURLM_OUT_OF_MEMORY returned from
curl_multi_perform() and curl_multi_socket*() invocations.
Closes#18432
After this patch, the codebase no longer overrides system printf
functions. Instead it explicitly calls either the curl printf functions
`curl_m*printf()` or the system ones using their original names.
Also:
- drop unused `curl_printf.h` includes.
- checksrc: ban system printf functions, allow where necessary.

Also:
- tests/server: replace local `sstrerror()` with `curlx_strerror()`.
- tests/server: show the error code next to the string, where missing.
- curlx: use `curl_msnprintf()` when building for src and tests.
(units was already using it.)
- lib: drop unused includes found along the way.
- curlx_strerror(): avoid compiler warning (and another similar one):
```

By making them defaults, then fixing and/or reshuffling remaining
exceptions as necessary.
- checksrc: ban by default: `snprintf`, `vsnprintf`, `sscanf`, `strtol`.
- examples: replace `strtol` with `atoi` to avoid a checksrc exception.
- tests/libtest: replace `strtol` with `atol`.
- tests/server: replace most `strtol` with `atol`.
- tests/server: replace most `strtoul` with `atol`/`atoi`.
- tests/server: drop no longer used `util_ultous`.
- fix typo in checksrc rules: `vsnprint` -> `vsnprintf`.
- update local exceptions.
Also:
- examples: ban curl printf functions. They're discouraged in user code.
- examples: replace curl printf with system printf.
Add `snprintf` workaround for <VS2015.
- examples/synctime: fix `-Wfloat-equal`.
- examples/synctime: exclude for non-Windows and non-UWP Windows.
- examples/synctime: build by default.
Closes#18823
Replace them by `curlx_open()` and `curlx_stat()`.
To make it obvious in the source code what is being executed.
Also:
- tests/server: stop overriding `open()` for test servers.
This is critical for the call made from the signal handler.
For other calls, it's an option to use `curlx_open()`, but
doesn't look important enough to do it, following the path
taken with `fopen()`.

If the source line had square brackets before the match, the stripping
of the banned function left the original line intact, and repeated the
check on it forever. E.g. with banned function `open` in `lib518.c`:
```c
t518_testfd[0] = open(DEV_NULL, O_RDONLY);
```
Closes#18775
By introducing wrappers for them in the curlx namespace:
`curlx_fopen()`, `curlx_fdopen()`, `curlx_fclose()`.
The undefine/redefine/`(function)()` methods broke on systems
implementing these functions as macros. E.g. AIX 32-bit's `fopen()`.
Also:
- rename `lib/fopen.*` to `lib/curl_fopen.*` (for `Curl_fopen()`)
to make room for the newly added `curlx/fopen.h`.
- curlx: move file-related functions from `multibyte.c` to `fopen.c`.
- tests/server: stop using the curl-specific `fopen()` implementation
on Windows. Unicode isn't used by runtests, and it isn't critical to
run tests on longs path. It can be re-enabled if this becomes
necessary, or if the wrapper receives a feature that's critical for
test servers.

Add script to run all Perl sources through `perl -c` to ensure no
issues, and run this script via GHA/checksrc in CI.
Fallouts:
- fix two repeated declarations.
- move `shell_quote()` from `testutil.pm` to `pathhelp.pm`, to
avoid circular dependency in `globalconfig.pm`.
Closes#18745
The implementation was incomplete and lesser than the other backends. No
one ever reported a bug or requested enhancements for this, indicating
that this backend was never used.
Closes#18700
Replace `WSASocketW()` with `CURL_SOCKET()`. Also replace a call
to `socketclose()` with `sclose()`. According to a comment,
`socketclose()` was chosen to silence test 1498 (and 2300) reporting
`MEMORY FAILURE`. These reports were accurate, and were caused by
calling `WSASocketW()` instead of `socket()` (now `CURL_SOCKET()`).
This also fixes the curl `sclose()` call on an error branch, which is
now correctly paired with a curl socket open. The mismatched open/close
calls caused an issue in TrackMemory-enabled (aka `CURLDEBUG`) builds.
Docs confirm that `socket()` is defaulting to overlapped I/O, matching
the replaced `WSASocketW()` call:
https://learn.microsoft.com/windows/win32/api/winsock2/nf-winsock2-socket#remarks
Also:
- checksrc: ban `WSASocket*()` functions.
- report `SOCKERRNO` instead of `GetLastError()` for socket calls,
to match the rest of the codebase.

Closes#18675
Before this patch `accept4()`, `socket()`, `socketpair()`, `send()` and
`recv()` system symbols were remapped via macros, using the same name,
to local curl debug wrappers. This patch replaces these overrides by
introducing curl-namespaced macros that map either to the system symbols
or to their curl debug wrappers in `CURLDEBUG` (TrackMemory) builds.
This follows a patch that implemented the same for `accept()`.
The old method required tricks to make these redefines work in unity
builds, and avoid them interfering with system headers. These tricks
did not work for system symbols implemented as macros.
The new method allows to setup these mappings once, without interfering
with system headers, upstream macros, or unity builds. It makes builds
more robust.
Also:
- checksrc: ban all mapped functions.
- docs/examples: tidy up checksrc rules.

- rand: drop interim macro `_random()`.
- windows: rename local macro `_tcsdup()` to `Curl_tcsdup()`.
To avoid using the reserved macro namespace and to avoid

- checksrc: ban `_tcsdup()` in favor of `Curl_tcsdup()`.
- tool_doswin: avoid redefining `_use_lfn()` (MS-DOS).
- tool_findfile: limit `__NO_NET_API` hack to AmigaOS.
Syncing this pattern with `lib/netrc.c`.
Follow-up to 784a8ec2c1#16279

- When an option name is used in text, this script no longer outputs the
short plus long version in the manpage output. It makes the text much
more readable.
This always showing both verions was previously done primarily to make
sure roffit would linkify it correctly, but since roffit 0.17 it
should link both long or short names correctly.
- When managen outputs generic text about options at the end of the
description it now highlights them properly so that they too get
linkified correctly in the HTML version. For consistency.

Tweaks around handling of --limit-rate:
* tracing: trace outstanding timeouts by name
* multi: do not mark transfer as dirty that have
an EXPIRE_TOOFAST set
* multi: have one static function to asses speed limits
* multi: when setting EXPIRE_TOOFAST remove the transfers
from the dirty set
* progress: rename vars and comment on how speed limit
timeouts are calculated, for clarity
* transfer: when speed limiting, exit the receive loop
after a quarter of the limit has been received, not
on the first chunk received.
* cf-ip-happy.c: clear EXPIRE_HAPPY_EYEBALLS on connect
* scorecard: add --limit-rate parameter to test with
speed limits in effect
Closes#18454
Changed strategy to start up and terminate resolver thread.
When starting up:
Start the thread with mutex acquired, wait for signal from thread that
it started and has incremented the ref counter. Thread set
pthread_cancel() to disabled before that and only enables cancelling
during resolving itself. This assure that the ref counter is correct and
the unlinking of the resolve context always happens.
When shutting down resolving:
If ref counting shows thread has finished, join it, free everything. If
thread has not finished, try pthread_cancel() (non Windows), but keep
the thread handle around.
When destroying resolving:
Shutdown first, then, if the thread is still there and 'quick_exit' is
not set, join it and free everything. This might occur a delay if
getaddrinfo() hangs and cannot be interrupted by pthread_cancel().
Destroying resolving happens when another resolve is started on an
easy handle or when the easy handle is closed.
Add test795 to check that connect timeout triggers correctly
when resolving is delayed. Add debug env var `CURL_DNS_DELAY_MS`
to simulate delays in resolving.
Fix test1557 to set `quick_exit` and use `xxx.invalid` as domain
instead of `nothing` that was leading to hangers in CI.
Closes#18263
Add support for CURLOPT_READFUNCTION with WebSocket urls when *not* in
connect-only mode, e.g. when using curl_multi_perform.
Install the callback function and set CURLOPT_UPLOAD. Return
CURL_READFUNC_PAUSE when having nothing more to send and unpause the
transfer when more data is ready.
This will send the read bytes in a WebSocket BINARY frame.
Add support for this mode in the pytest "ws_data" client and have all
tests run in 'curl_ws_send/recv' and 'peform' mode as well.
Add `curl_ws_start_frame()`. Document, cover in libcurl-ws.md and
explain the READFUNCTION mode for websockets.
Add example `websocket-updown` for this.
Closes#17683
Adds `curl_off_t curl_multi_get_offt(CURLM *multi_handle, CURLMinfo_offt
info)` to the multi interface with enums:
* CURLMINFO_XFERS_CURRENT: current number of transfers
* CURLMINFO_XFERS_RUNNING: number of running transfers
* CURLMINFO_XFERS_PENDING: number of pending transfers
* CURLMINFO_XFERS_DONE: number of finished transfers to read
* CURLMINFO_XFERS_ADDED: total number of transfers added, ever
Add documentation for functions and info enums.
Add use in the curl command line tool to replace two static
variables counting the same "from the outside".

Also:
- GHA/linux, macos: test `install` with autotools too.
- GHA/linux, macos: enable fish and zsh completion in an autotools job.
- scripts: drop dynamic perl checks redundant after this patch.
- scripts: drop two interim variables.
- autotools: make `build-certs` target check perl first.
- autotools: replace `$(PERL)` with `@PERL@` to match the pattern used
in most automake scripts. For consistency. This makes `PERL` be
defined at configure-time, as opposed to make-time, for these cases
now.
