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.

These tests wrote to a hardcoded "/tmp/" path which does not exist on
Windows, causing the file write to silently fail and the subsequent
make_file_body / make_file_provider call to return zero-sized data.
Use a relative path under the test working directory instead so the
test runs identically on every platform.
Also dump the shard log when a shard's process exits non-zero even
when the gtest summary appears clean (e.g. sanitizer report after
the suite, or assertion-based abort) — previously such failures were
detected only via overall rc and showed no diagnostic output.

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.

* Fix#2427
* Use setarch -R on Linux to fix ASAN crash on WSL2
WSL2 uses high-entropy ASLR which conflicts with ASAN's shadow memory
requirements, causing the ASAN runtime to crash at startup. Running tests
via setarch -R (ADDR_NO_RANDOMIZE) disables ASLR for the test process,
allowing ASAN to initialize correctly.
- Added `set_websocket_max_missed_pongs` method to configure unresponsive-peer detection.
- Updated README and documentation to clarify WebSocket limitations and features.
- Introduced tests for detecting non-responsive peers and ensuring responsive peers do not trigger timeouts.
The server listens on AF_INET6 only (::1), so the test fails:
[ RUN ] WebSocketIntegrationTest.SocketSettings
test/test.cc:17160: Failure
Value of: client.connect()
Actual: false
Expected: true
Fixes#2419.
