I added it just in case when removing enabled-by-default memdebug
from test servers. Apparently it broke after recent changes. It's
probably not a widely used feature and does not seem to be worth fixing.
It creates odd dependencies as the error message indicates:
```

Instead of relying on CMake's built-in unity feature, use `mk-unity.pl`,
as already done with autotools. It simplified the build, shortens logs
and makes debugging easier because of the fewer build variations.
It also allows testing / fixing with cmake and those automatically apply
to autotools builds too. cmake builds can be much-much faster, esp.
when working the builds themselves.
It also enables "unity" in old cmake versions. Basically every test
target is a single generated .c source.
Also:
- drop a `lib` unity workaround for libtests with autotools after fixing
the issue in libtests itself. It drops a few exceptions and makes
libcurl build faster (in autotools unity).
- fix another `lib` autotools unity issue and drop the workaround for it
from `mk-unity.pl`. `srcdir` was missing from the header path.
- simplify `mk-unity.pl` command-lines, drop exclusions.

Fixes#17612Closes#17614
When `curl_easy_cleanup()` is invoked while still being part
of a multi handle, the code will auto-remove it. But since the
connection was detached first, the code in
`curl_multi_remove_handle()` that invalidates dirty connections
did not bite.
Attach the connection *after* the possible remove from a multi
handle, so that connection reuse can be prevented.
Add test753 to reproduce and verify the fix. This required adding
the new debug env var CURL_FTP_PWD_STOP, to have a transfer return
from multi_perform() early with a connection that does not show
and pending input.

- Return CURLE_OK if the engine successfully loaded.
Prior to this change:
When loading an openssl engine, the result code is initialized to
CURLE_SSL_ENGINE_NOTFOUND, but is never set to CURLE_OK when the engine
was successfully loaded. This causes curl to error out, falsely stating
engine not found when it actually was.
Broken since f2ce6c46 (precedes 8.14.0) which added support for using
engines and providers at the same time.
Fixes https://github.com/curl/curl/issues/17617
Closes https://github.com/curl/curl/pull/17618
- Align --cacert behaviour with OpenSSL and LibreSSL.
This changes the default behavior of Schannel manual certificate
verification, which is used when the user provides their own CA
certificates for verification, to accept partial chains. In other words,
the user may provide an intermediate certificate without having to
provide the root CA.
Win8/Server2012 widened the PKIX chain traversal API to allow
certificate traversal to terminate at an intermediate.
This behaviour (terminate at the fist matching intermediate) is the
default for LibreSSL and OpenSSL (with OpenSSL allowing control via
CURLSSLOPT_NO_PARTIALCHAIN).
This change uses the new API if it is available, and also allows the
behaviour to revert legacy if CURLSSLOPT_NO_PARTIALCHAIN is present.
Closes https://github.com/curl/curl/pull/17418
Make test bundles the default. Drop non-bundle build mode.
Also do all the optimizations and tidy-ups this allows, simpler builds,
less bundle exceptions, streamlined build mechanics.
Also rework the init/deinit macro magic for unit tests. The new method
allows using unique init/deinit function names, and calling them with
arguments. This is in turn makes it possible to reduce the use of global
variables.
Note this drop existing build options `-DCURL_TEST_BUNDLES=` from cmake
and `--enable-test-bundles` / `--disable-test-bundles` from autotools.
Also:
- rename test entry functions to have unique names: `test_<testname>`
This removes the last exception that was handled in the generator.
- fix `make dist` to not miss test sources with test bundles enabled.
- sync and merge `tests/mk-bundle.pl` into `scripts/mk-unity.pl`.
- mk-unity.pl: add `--embed` option and use it when `CURL_CLANG_TIDY=ON`
to ensure that `clang-tidy` does not miss external test C sources.
(because `clang-tidy` ignores code that's #included.)
- tests/unit: drop no-op setup/stop functions.
- tests: reduce symbol scopes, global macros, other fixes and tidy-ups.
- tool1621: fix to run, also fix it to pass.
- sockfilt: fix Windows compiler warning in certain unity include order,
by explicitly including `warnless.h`.

`SSL_pending()` only checks if the *current* TLS packet has more data.
There might be more data in SSL's buffers.
`SSL_has_pending()` only checks if there is data in buffers, but does
*not* check if there is a complete TLS packet that can be decoded.
If we only check the first, we will poll on socket events without having
processed all data and may stall. If we only check the second, we would
busy loop without SSL_read() ever giving something.
Add the flag `connssl->input_pending` that is set on incoming data in
the BIO receive. Clear the flag when encountering a CURLE_AGAIN on
the filters receive (via SSL_read()) or see an EOF.

The secure transport vTLS backend was the only Curl_ssl struct instance
that populated the false_start field. Since its removed, we can now
remove that field entirely. This was a protocol feature specific to TLS
1.2 that has been replaced by the more widely adopted TLS 1.3 early data
mechanisms.
--false-start is now deprecated

After this patch there is no more double/multiple compile of the same
libtest source under a different libtest ID. Each libtest is compiled
once, and changing behavior at runtime based on test ID.
- drop recently added physical clones for two prevously multi-compiled
tests:
- merge lib587 into lib554 again, branch at runtime.
- merge lib645 into lib643 again, branch at runtime.
- replace existing dynamic branching to use `testnum` instead of
a manually rolled `testno` based on an extra command-line argument.
lib1571, lib1576.
- mk-bundle.pl: stop defining `LIB*` macros. No longer used.
- libtests: drop all `LIB*_C` guards.

Convert the debug-only handling of SSL_ERROR_SYSCALL so that it is

The checks for a connection being "too long idle" or "too old" where
rounding down the elapsed time to seconds before comparing to the
configured max values. This caused connections to be reused for up to
999ms longer than intended.
Change the compares to scale the configured seconds up to ms, so
connection will properly be "too old" 1 ms after the coonfigured values.

These libraries do not support TLS 1.3 and have been marked for removal
for over a year. We want to help users select a TLS dependency that is
future-proof and reliable, and not supporting TLS 1.3 in 2025 does not
infer confidence. Users who build libcurl are likely to be served better
and get something more future-proof with a TLS library that supports
1.3.

Public `curl/curl.h` includes these headers for non-Windows platforms
without further conditions. This makes it safe to assume these headers
do exist, allowing to save two feature checks for non-Windows targets.
`sys/time.h` is also assumed on Windows with mingw-w64, for declaring
`gettimeofday()`.

IBM-specific macro, no need to unset it on other platforms.

Trying to avoid the occasional ~6-minute long delays seen in the OpenBSD
since last week. The long delay causes the CI job to timeout and fail:
https://github.com/curl/curl/actions/workflows/non-native.yml?page=2&query=branch%3Amaster
The exact reason is or test number is unknown. I base this attempt on
looking at the first occurrences and possible patches that may be
related.

Using a mixture of techniques to avoid symbols collisions:
- reduce scope.
- add `t*_` / `T*_` prefix.
- move shared functions to `testutil.c`.
(`suburl()`, `rlim2str()`)
- clone re-used lib*.c sources.
(lib587, lib645)
- include shared symbols just once in re-used `lib*.c` sources.
(using `LIB*_C` guards.)
- drop re-used `lib*.c` sources where they were identical or
unused.
- make macros global.
- #undef macros before use.
What remain is the entry functions `test`, and `unit_setup`,
`unit_stop` in unit tests.
Also:
- fix formatting and other minor things along the way.
- add `const` where possible.
- sync some symbol names between tests.
- drop `mk-bundle-hints.sh` that's no longer necessary.

Closes#17413
Extend MSVC jobs with the option to use MSYS2 binary package as DLL
dependencies. Allow to use them alone (without vcpkg) or combined with
vcpkg packages. This saves the trouble of building these packages from
source and cache them manually.
This solution requires two tricks:
- workaround for zlib which installs a target-specific `zconf.h` that's
not portable between platforms and C compilers.
- manual dependency configuration in CMake to ensure linking against
the MSYS2 DLLs (and not it static libs). Static libs aren't portable
to MSVC due to missing symbols `__chkstk_ms`, `_stack_chk_fail`,
`_memcpy_chk`, `_stack_chk_guard`, and potentially other issues. CMake
in MSVC mode, `linker.exe` and `pkg-config` pick the static libs by
default. To pick `.dll.a` in favour of `.a`, these tools would have
to be taught about this convention. An alternative is deleting static
libs and see if `.dll.a` are picked-up automatically.
Using MSYS2 packages adds an install step taking 15-45 seconds per job.
It allowed to:
- re-enable libpsl for all MSVC jobs.
- convert the Intel 64-bit job to use MSYS2 without vcpkg, enabling
brotli, zstd, OpenSSL 3.5.0, libssh2 (with OpenSSL cryprography) and
nghttp2.
Using the same technique it's possible to re-enable more features
in MSVC builds, e.g. GnuTLS (also with H3), LibreSSL, mbedTLS, nghttp3,
ngtcp2, libssh, c-ares, gsasl, and replace vcpkg zlib, for faster runs.
What's missing compared to vcpkg is BoringSSL and wolfSSL
(the MSYS2-supplied build doesn't fit curl's requirements IIRC). These
could be built and cached manually.
Also:
- add workaround for zlib (classic) which uses a generated `zconf.h`,
rendering the MSYS2 zlib header incompatible with MSVC.
- set the correct `msystem` for arm64.
- allow using MSVC without vcpkg.
