Under ASAN+mbedTLS, the default 4-way sharding loads CI runners enough
that timing-sensitive ServerTest cases (Delete, PostMethod2, GetStreamed,
...) flake on what looks like first-request keep-alive reuse. Reducing
to 2 shards halves contention and historically stabilizes these on local
runs. The total test time goes up roughly 1.5x (still well under the job
budget) which is an acceptable trade for reliability.

These tests reach out to external services (httpbin, YouTube, ...) and
flake on CI runners whenever those services are slow or unreachable.
The previous shard runner script silently masked these failures; now
that runs report them faithfully, default the filter to -*_Online.
Override via workflow_dispatch + the gtest_filter input to include
them when explicitly desired.

Skip SSLTest.ResponseBodyTerminatedByConnectionClose under
CPPHTTPLIB_MBEDTLS_SUPPORT until the close_notify-mid-response handling
is brought into parity with the OpenSSL and wolfSSL backends. The test
verifies a successful read past the server's close, which mbedTLS
currently reports as an I/O error.
Mark the mbedTLS matrix legs (ubuntu and macos) as
continue-on-error: true. Several timing-sensitive ServerTest cases
(PostMethod2, GetStreamed, Brotli, ...) flake under ASAN+mbedTLS in
ways unrelated to cpp-httplib code; isolating these into a non-blocking
slot keeps master green while the flakiness is investigated separately.

Add a libwolfssl entry to lsan_suppressions.txt to mirror the existing
libcrypto rule: the wolfSSL ECC subsystem caches per-handshake buffers
that are only freed at library shutdown, which the test binaries do
not perform. These are not leaks in cpp-httplib code.
Disable fail-fast on the ubuntu / macos / windows matrices so a failure
in one TLS backend does not cancel the others; with the runner now
detecting failures correctly, we want to see the full picture per run.

The previous logic considered a shard "passed" if its log contained any
[ PASSED ] line, missing the case where some tests pass and some fail
(both [ PASSED ] N tests. and [ FAILED ] M tests, listed below:
appear in the gtest summary). Exit codes from the test binaries were
also ignored.
Now require both: an [ PASSED ] line, no [ FAILED ] line, and a
zero exit code. Track each shard's PID so wait can surface non-zero
exits.

* Add reproducer for #2431 (getaddrinfo_a use-after-free)
On Linux/glibc, getaddrinfo_with_timeout() runs DNS asynchronously via
getaddrinfo_a(GAI_NOWAIT) using a stack-local gaicb. When gai_suspend()
hits the connection timeout, gai_cancel() is called and the function
returns immediately — but gai_cancel() is non-blocking and can return
EAI_NOTCANCELED, leaving the resolver worker thread alive and still
referencing the destroyed stack frame.
Adds three opt-in gtest cases (GetAddrInfoAsyncCancelTest.*) that
exercise the cancel path repeatedly. They are gated on Linux/glibc +
CPPHTTPLIB_USE_NON_BLOCKING_GETADDRINFO at compile time, and on the
CPPHTTPLIB_TEST_ISSUE_2431=1 env var at runtime, so a normal `make
test` run is unaffected.
Also adds a dedicated CI job (issue-2431-repro) and a Docker-based
local runner (test/run_issue_2431_repro.sh) that sinkhole UDP/53 so
the timeout branch is taken, and run the test under ASAN/LSAN. With
the bug present these runs are expected to fail; with a fix applied
they should pass.

* Fix split build for #2431 reproducer tests
The new GetAddrInfoAsyncCancelTest cases call detail::getaddrinfo_with_timeout
directly. In split builds (make test_split) split.py moves the definition into
httplib.cc and strips `inline`, so the symbol is not declared in the public
httplib.h and test.cc fails to compile -- breaking the ubuntu/test-no-exceptions
CI jobs that the PR description says should be unaffected.
Add a forward declaration in test.cc, gated by the same #if as the tests
themselves, so it links against the split-build symbol without changing the
header-only build.
* Cap issue-2431 repro job at 5 minutes
The bug manifests as orphan getaddrinfo_a resolver workers that keep the
runner from completing job teardown -- the previous run had all steps
succeed in ~1m37s but then hung in "Cleaning up orphan processes" for
~57m before GitHub force-killed the job.
A job-level timeout-minutes makes the failure signal fast and predictable:
bug present -> killed at 5 min, bug fixed -> ~2 min pass. Step-level timeout
isn't enough since the hang is in post-job cleanup, not the test step.
* Enable ASAN detect_stack_use_after_return for #2431 repro
The bug is a textbook stack-use-after-return: a stack-local struct gaicb
is destroyed when getaddrinfo_with_timeout returns after gai_cancel()
yields EAI_NOTCANCELED, then the still-live resolver worker thread writes
back into the freed frame. ASAN's detect_stack_use_after_return is the
direct detector for exactly this pattern -- enabling it lets the failure
surface as a clear ASAN diagnostic during the test run instead of as an
orphan-process hang at job teardown.
* Revert ASAN detect_stack_use_after_return for #2431 repro
The option did not detect the bug in CI -- the resolver worker write
likely lands on the heap (via the gaicb's pai pointer) or happens after
the test process exits, neither of which stack-use-after-return can
catch. Roll back to relying on the job-level timeout: bug present ->
post-cleanup hangs ~8min then job-level timeout cancels at 10min total;
bug fixed -> job completes in ~2min.
* Switch issue-2431 repro to a delayed loopback DNS test fixture
The previous repro setup dropped UDP/53 outright, which made glibc's
resolver hang forever on every lookup -- the worker never actually
received a response and so never reached the buggy write-back path
that #2431 is about. As a result, neither the broken HEAD nor the
fix made any visible difference in CI: both produced "tests pass +
post-cleanup hangs ~10min" because the orphan resolver thread is a
structural property of *any* getaddrinfo path on a hung resolver,
not a property of the bug.
Replace the sinkhole with a small loopback test fixture
(test/dns_test_fixture.py, ~50 lines, stdlib only) that answers DNS
queries after a 3s delay -- longer than the test's 1s timeout. An
iptables NAT rule routes the test job's lookups to the fixture
without touching /etc/resolv.conf, so the rest of the runner's DNS
behaviour is unaffected.
With ASAN's detect_stack_use_after_return enabled, the worker's
late write-back into the destroyed gaicb stack frame is now caught
as a stack-use-after-return diagnostic, so the broken HEAD fails
fast at the test step (clear red) and the fix turns the same job
green in well under a minute.
Same fixture is wired into both the GitHub Actions job and the
docker-based test/run_issue_2431_repro.sh script, so local repro on
macOS and CI repro on Linux exercise the identical path.

This integrates the "main" test suite (test/test.cc) in Meson.
This allows to run the tests in the CI with the Meson-built version of
the library to ensure that nothing breaks unexpectedly.
It also simplifies life of downstream packagers, that do not have to
write a custom build script to split the library and run tests but can
instead just let Meson do that for them.
In order to test the split version (.h + .cc via split.py):
- Added a test_split program in the test directory whose main purpose is
to verify that it works to compile and link the test case code against
the split httplib.h version.
- Moved types needed for test cases to the “header part” of httplib.h.
Also added forward declarations of functions needed by test cases.
- Added an include_httplib.cc file which is linked together with test.cc
to verify that inline keywords have not been forgotten.
The changes to httplib.h just move code around (or add forward
declarations), with one exception: detail::split and
detail::process_client_socket have been converted to non-template
functions (taking an std::function instead of using a type parameter for
the function) and forward-declared instead. This avoids having to move
the templates to the “header part”.
