The existing m_isUploadScheduled check then skipped scheduling a new task, silently dropping the requested latency for force-scheduled profile changes. Propagate the requested latency to m_runningLatency under the same mutex when this race occurs. uploadAsync re-reads m_runningLatency inside its own LOCKGUARD, so a task that hasn't yet entered that critical section will pick up the new latency. If uploadAsync has already cleared m_isUploadScheduled (past its LOCKGUARD), the existing fallthrough at line 184 schedules a fresh task with the new latency. Add a regression test using a fake dispatcher whose Cancel always returns false, asserting that a force-scheduled call updates m_runningLatency without enqueueing a duplicate task.

Cancel() only pointer-compares today, but the stale pointer is fragile -- a reused heap address could make Cancel() match and cancel the wrong task (ABA), any future deref would be a use-after-free, and the caller got no signal that scheduling was dropped. - ITaskDispatcher: add a non-pure virtual QueueWithResult(Task*) reporting whether the task was accepted. The default delegates to Queue() and returns true, so existing/third-party dispatchers are unaffected (no signature change). - WorkerThread: implement QueueWithResult (returns false on the shutdown-drop path); Queue() now delegates to it. - scheduleTask(): return an empty DeferredCallbackHandle when the task was not queued, so no dangling pointer is retained and Cancel() is a safe no-op. - Test ScheduleTaskReturnsNoOpHandleWhenTaskDropped verifies the handle is a no-op and the dispatcher's Cancel() is never invoked with a freed pointer.

The callback owns a strong ref to CurlHttpOperation, so when it releases the last ref the ~CurlHttpOperation destructor runs on the async thread itself. libstdc++'s std::future<>::~future implicitly calls _Async_state_impl::~_Async_state_impl, which calls _M_complete_async -> _M_join via std::call_once. On the async thread that's a self-join; call_once throws std::system_error(EDEADLK). Because the throw escapes a noexcept destructor, terminate() aborts the process. A try/catch around the future cannot rescue this — destructors of std::future are noexcept. Fix === Move the future onto a detached helper thread before its destructor runs. The helper is by definition NOT the async thread (we'd only be on the async thread if its work already finished), so the implicit join completes immediately. On the common path (destruction from the caller thread) it costs one short-lived thread spawn that exits in microseconds. Verified locally with sister + modules linked: all 113 FuncTests pass, including all 25 ECSClientFuncTests (which include the formerly-fatal GetConfigs).

That removed the cross-thread lifetime guarantee the old result.wait() provided: when the operation is destroyed from another thread while the async Send() is still running, the destructor would proceed to curl_easy_cleanup()/ReleaseResponse() and destroy the by-reference request body while the worker thread is still using them -> use-after-free. Restore the guarantee while keeping the EDEADLK self-join fix: - Record the async task's thread id (atomic) when SendAsync's task starts. - In the destructor, compare std::this_thread::get_id(): * self-join (destroyed from within our own async callback, e.g. EraseRequest drops the last reference): the work is necessarily complete, so defer the future's join to a detached helper thread instead of joining on this (the async) thread, avoiding EDEADLK. * cross-thread: result.wait() to keep the curl handle, response buffer and by-reference request body alive until the async Send() finishes. - Heap-allocate the deferred future first so a rare std::thread spawn failure leaks the already-finished future rather than self-joining (EDEADLK) or letting std::system_error escape this noexcept destructor (std::terminate). - Refresh the stale HttpClient_Curl.cpp lifetime comment. Logic validated with a standalone C++11 repro under AddressSanitizer: the cross-thread path waits (no UAF) and the self-join path does not deadlock.

This contradicts the fail-closed OfflineStorage_SQLite::DeleteRecords and the Room backend. Guard an empty filter and return without deleting; intentional full clears use DeleteAllRecords(). 2) OfflineStorage_SQLite::StoreRecord ignored the bool returned by SqliteStatement::execute(), returning true and bumping m_DbSizeEstimate even on a real write failure (SQLITE_FULL/IOERR/etc). The event is silently lost with no OnStorageFailed notification and the size estimate drifts. Capture the result; on failure log, notify the observer, and return false (skipping the size bump). Tests: added MemoryStorageTests.DeleteRecordsWithEmptyFilterDoesNotDeleteAll (fails without the guard -- the queue is wiped to 0; passes with it). The StoreRecord write-failure path isn't unit-testable here (the insert is REPLACE INTO with no constraint to violate), so it's covered by build + review. Verified locally on Linux: all 9 MemoryStorageTests and 32 OfflineStorageTests_SQLite pass.

OfflineStorageHandler::Flush() previously drained the in-memory queue with GetRecords() (which removes records) and handed them to StoreRecords() before confirming persistence. On a partial/total disk write failure the un-persisted records were already gone from memory and never re-queued -> events lost. Flush() now drains into a local batch, persists one record at a time, and re-inserts only the records that fail to persist (so failures are retried, not lost). Per-record StoreRecord() is used deliberately: a batched StoreRecords() only returns a count, so on a partial failure we could not tell which records to re-queue, and re-storing already-saved records would duplicate them (no unique record_id constraint). Also null-guards the dbSizeBeforeFlush read so Flush() is safe with disk-only storage (CFG_INT_RAM_QUEUE_SIZE == 0). Adds OfflineStorageHandlerFlushTests.FailedDiskWriteDuringFlushReturnsRecordsToMemory (records the SQLite store rejects stay in memory after Flush; verified it fails against the previous GetRecords()-based Flush). Closes the separate PR #1496.

OfflineStorage_SQLite: StoreRecords() now inserts the whole batch in a single BEGIN EXCLUSIVE / COMMIT (one fsync) instead of one transaction per record (~11x at 200 records, ~40x at 1000 vs the SDK's vendored sqlite). Shared per-record logic is factored into isValidRecord / insertRecordUnsafe / checkStorageSizeLimits. The batch is all-or-nothing: if any insert fails, the transaction is rolled back (new SqliteDB::rollback / DbTransaction::markForRollback) and the size estimate is undone, so callers can re-queue the whole batch without risking duplicate rows (the events table has no unique record_id constraint). OfflineStorageHandler::Flush() now uses the batched StoreRecords() to persist a drained batch in one transaction. Because StoreRecords() is all-or-nothing, on failure nothing is committed and Flush returns every record to the in-memory queue for retry -- realizing the batching speedup while keeping the no-event-loss / no-duplicate guarantee. StoreRecords/StoreRecord report write failures via OnStorageFailed after the transaction closes; validation runs before the transaction. Adds OfflineStorageTests_SQLite.StoreRecordsBatchStoresAllRecords. Full UnitTests (527) pass. Closes PR #1497.

OfflineStorageHandler::Flush() treats totalSaved < records.size() as a batch failure and re-queues ALL drained records, which would duplicate the valid records that were actually stored. Make StoreRecords() truly all-or-nothing: if ANY input record is invalid, store nothing and return 0 (invalids are still reported via isValidRecord()). Combined with the existing rollback-on-write-failure, StoreRecords() now returns either records.size() (whole batch committed) or 0 (nothing committed), so Flush's re-queue-all-on-short-return can never duplicate records. Adds OfflineStorageTests_SQLite.StoreRecordsBatchWithAnyInvalidStoresNothing.

Both disk backends are all-or-nothing (SQLite rolls back; Room returns 0 on a failed JNI batch), so the only meaningful "failure" value is 0.

Rather than detect-and-defer that self-join (the previous approach: published thread id + atomic flag + heap-move the future to a detached helper, with OOM/ thread-exhaustion fallbacks), remove the joining future entirely: - CurlHttpOperation now derives from enable_shared_from_this. SendAsync runs Send() on a detached std::thread that holds a shared_ptr keepalive to the operation, so the operation (and its curl handle, response buffer, and by-reference request body) stays alive until the worker finishes -- the same lifetime guarantee the destructor's result.wait() used to provide. - There is no future, so ~CurlHttpOperation never joins anything and is safe on any thread, including the worker thread itself. The destructor drops to plain curl cleanup. - Removes the future member, the m_asyncThreadId/m_asyncThreadIdSet machinery, and the / includes. Net -54 lines in the client. Adds HttpClientCurlTests.SendAsync_DestroyOnWorkerThread_NoSelfJoin, which drops the last external reference from inside the callback (on the worker thread) -- the exact #1481 trigger.

With the self-keepalive worker the operation can outlive the request, so a reference into CurlHttpRequest::m_body could dangle mid-send. CurlHttpOperation now takes the body by value and owns it, so it is valid for the operation's whole lifetime regardless of when the request is released. Costs one body copy per request (the prior zero-copy relied on the blocking wait that caused #1481). - Detached-worker exceptions (comment 2): an exception escaping Send()/callback would call std::terminate, whereas the old std::async captured (and effectively swallowed) it. Wrap the worker body in try/catch to preserve the non-terminating behavior. - Test (comment 4): replace the raw new/delete shared_ptr box with a shared_ptr> whose contained pointer is reset in the callback, so it cannot leak if SendAsync throws.

On the self-Join path (a task on the worker thread triggers the dispatcher's own teardown) Join() detaches instead of joining and deliberately skips that cleanup, because the still-running worker may access the queues. As a result, future-dated timer tasks left in m_timerQueue when the worker breaks on the shutdown sentinel were leaked. Fix: when the worker processes the Shutdown item it now drains and deletes any remaining m_queue/m_timerQueue entries under m_lock before exiting. This closes the detach-path leak without racing Join() (the worker owns the queues while it runs) and matches the join()-path behavior of dropping un-run work at shutdown. Validated on Linux (WSL, Debug): PalTests + TransmissionPolicyManagerTests (47) pass and full FuncTests (40, incl. the teardown smoke test) pass.

This PR changed these LOG_TRACE format strings from %d to %lld but passed std::chrono::milliseconds::rep directly. That rep is implementation- defined and is long on LP64 (Linux/macOS), so %lld (which expects long long) is a -Wformat mismatch -- an error under the project's -Wall -Werror in logging-enabled (HAVE_MAT_LOGGING) builds, and formally UB in the varargs call. Cast each count() to long long so the format always matches on every data model. This mirrors the cast this PR already applies to delta (static_cast with %llu) a few lines up. Verified: clang 18 -Wall -Werror -Wextra flags the uncast %lld as "format specifies type 'long long' but the argument has type 'rep' (aka 'long')" and accepts the cast form. TransmissionPolicyManagerTests (40) pass.

Added an explicit include so the header is self-contained. HttpClient_Curl.hpp SendAsync (comment 3548205850): the thread-start fallback only caught std::system_error, but std::thread construction can also throw std::bad_alloc while allocating the callable. Broadened the catch to const std::exception& so any thread-start failure still falls back to a synchronous run and never escapes SendAsync() (which would terminate on the PAL worker thread). HttpClientCurlTests.cpp (comment 3548205863): dropped the misleading "connTimeout=1 bounds it" note -- CurlHttpOperation ignores its httpConnTimeout arg (WaitOnSocket uses the HTTP_CONN_TIMEOUT constant), so the .invalid host's immediate name- resolution failure, not the timeout, is what makes Send() fail fast.

Every CurlHttpOperation is created via make_shared (HttpClient_Curl.cpp:89), so this is safe today, but if a future caller ever constructs one outside a shared_ptr (stack / unique_ptr) shared_from_this() throws std::bad_weak_ptr, which would escape SendAsync() BEFORE the thread-start try/catch and could terminate the caller thread -- breaking the "SendAsync never lets an exception escape / the callback is always invoked" property established in the earlier rounds. Guarded shared_from_this() with a std::bad_weak_ptr catch that falls back to a synchronous run (the caller owns the non-shared object for the duration).

If Send() threw, the request was left outstanding and its IHttpClient callback never completed, which could hang the upload/cancel path. Restructured so Send() is guarded on its own, a thrown Send() sets a failure result (res = CURLE_FAILED_INIT), and the callback is then invoked unconditionally (itself guarded so a throwing callback can't escape the detached worker). The 'always invoked' contract now holds literally. Validated on Linux (WSL, Debug): 13 HttpClientCurl* unit tests pass; FuncTests 39/39.

StoreRecords/StoreRecord decided success only from per-insert step results; the COMMIT ran in ~DbTransaction and its bool result was discarded. An all-inserts-OK batch whose COMMIT failed (e.g. SQLITE_FULL/IOERR) returned the full count, so Flush -- which drains records from memory before storing and only re-queues on a zero return -- treated the undurable batch as saved and dropped the records. DbTransaction now exposes commit(), which verifies COMMIT, rolls back on failure so the transaction is never left open, and returns false; StoreRecords/StoreRecord report the failure so Flush re-queues the batch. - A single permanently-invalid record wedged the whole batch. Any record failing validation made StoreRecords store nothing and return 0, and Flush re-queued the entire batch, so the poison record was re-drained and re-rejected on every flush, blocking every valid record behind it and growing the in-memory queue without bound. Invalid records are now dropped (reported once) and the valid remainder is stored all-or-nothing. Tests: rewrite the flush regression test to use a real transient failure (an unopenable database) instead of an invalid record; add a test that invalid records are dropped rather than wedging the queue; update the SQLite batch test to expect invalid-dropped / valid-stored. Also drop the issue-number reference from a TransmitProfiles test comment.

In synchronous-handler builds (USE_SYNC_HTTPRESPONSE_HANDLER, which is defined by default) that callback runs HttpClientManager::onHttpResponse, which deletes the IHttpResponseCallback before returning. The destructor then dispatched OnDestroy through the now-dangling m_callback -- a use-after-free on every completed request (benign until the freed memory is reused; caught by ASAN). Track completion in an atomic flag set right after the completion callback runs, and skip the destructor's OnDestroy dispatch once completed. OnDestroy still fires when the operation is destroyed before completing (aborted, or a construction/dispatch failure), where m_callback is still valid. Add a regression test (SendAsync_NoOnDestroyDispatchAfterCompletion) that keeps the callback alive and asserts OnDestroy is not dispatched after completion; it fails without the guard and passes with it.

A task running on the worker thread can drop the last reference (e.g. by tearing down its LogManager/PAL), which ran ~WorkerThread -> Join() synchronously inside the task: Join() detached the thread and returned, freeing the object while threadFunc was still on the stack below the task. threadFunc then kept touching freed members (m_itemInProgress, the locks, and the queues it drains at shutdown) -- a use-after-free / heap corruption confirmed by AddressSanitizer. Give the worker a custom shared_ptr deleter: when the last reference is released on the worker thread itself, detach and defer destruction to the thread, which deletes itself only after its loop has broken and all member access is done. On any other thread the object is deleted immediately as before (~WorkerThread joins the worker first). Add a PalTests regression test that drops the last reference from within a task running on the worker thread; it is clean under AddressSanitizer with the fix and reports heap-use-after-free without it.

Store m_workerId as a plain std::thread::id guarded by the existing recursive m_lock instead; the self-dispose check reads it under the lock. - Passing std::thread::id to LOG_INFO's printf-style '%u' is undefined behavior (varargs). Format the id with std::hash and '%zu' at both log sites (the constructor's 'Started new thread' and threadFunc's 'Running thread'). This was pre-existing; the surrounding change touches these lines.

From d325700a1be70ad20cf4d67a921f700dc29dad85 Mon Sep 17 00:00:00 2001 From: Bhagirath Mehta Date: Sat, 1 Aug 2026 00:30:47 -0500 Subject: [PATCH 081/225] Guard OfflineStorageHandler::Flush against leaking StartActivity on exception Flush() paired ILogManager::StartActivity()/EndActivity() manually -- StartActivity() at the top, EndActivity() on the last line -- with no RAII guard and no try/catch in between. StoreRecords(), the optional checkpoint Flush(), and IOfflineStorageObserver::OnStorageRecordsSaved() are all real throw surfaces (disk I/O, a full/locked DB, or an observer implementation). If any of them threw, EndActivity() was skipped and m_pause_active_count was permanently leaked, so every later FlushAndTeardown()'s PauseActivity()+WaitPause() would deadlock waiting for a count that could never reach zero. This reproduced as a live macOS deadlock on main. Add ActivityGuard, an RAII wrapper matching the existing safe pattern already used by PauseGuard (TransmissionPolicyManager.cpp) and ActiveLoggerCall (Logger.cpp): its destructor calls EndActivity() on every exit path, including exception unwinding. Flush() now constructs the guard instead of calling StartActivity() directly, checks IsActive() instead of the raw bool, and no longer calls EndActivity() explicitly -- the guard's destructor handles it uniformly for both the normal-completion and the StartActivity()-returned-false early-return paths. Validated: full WSL Release build + complete UnitTests suite, 536/536 passed. No exception-injection regression test was added (Flush() has no existing throwing-observer test harness to extend); the fix's correctness rests on C++'s standard guaranteed-destructor-during-unwinding semantics, the same guarantee the two existing PauseGuard/ActiveLoggerCall call sites already rely on.

WinHTTP is Microsoft's own recommended replacement for exactly that scenario, and 1DS's dominant embedding scenario (background/service telemetry) is the one WinInet is not designed for. Add lib/http/HttpClient_WinHttp.hpp/.cpp implementing the same IHttpClient/IHttpRequest contract as HttpClient_WinInet using WinHTTP's async API instead. Key differences from a direct port of the WinInet implementation: - WinHttpOpen uses WINHTTP_ACCESS_TYPE_AUTOMATIC_PROXY (falling back to WINHTTP_ACCESS_TYPE_NO_PROXY on an older OS that rejects it) instead of WinInet's INTERNET_OPEN_TYPE_PRECONFIG, so proxy resolution does not require a logged-on user. - WinHTTP's async model has one distinct callback status per stage (SENDREQUEST_COMPLETE -> HEADERS_AVAILABLE -> DATA_AVAILABLE/READ_COMPLETE loop -> REQUEST_ERROR) rather than WinInet's single INTERNET_STATUS_REQUEST_COMPLETE, and a FALSE return from an async-handle call is always a genuine synchronous failure (never ERROR_IO_PENDING as with WinInet). - The response-size cap (MAX_HTTP_RESPONSE_SIZE, see #1508) is enforced the same way, before every read. - The MS-root certificate check rebuilds the chain via CertGetCertificateChain, since WinHttpQueryOption only hands back the leaf certificate rather than WinInet's ready-made chain context. - Request lifetime uses std::enable_shared_from_this / shared_ptr rather than raw-pointer self-ownership: WinHttpCloseHandle on a request with a pending operation blocks the calling thread until that operation's completion callback (which runs on a different WinHTTP-internal thread) finishes running. Holding the shared requests-map mutex across that call -- WinInet's pattern, safe there because its callback runs synchronously on the calling thread -- deadlocks here, since the callback thread needs that same mutex to erase() the completed request. shared_ptr lets cancellation release the map lock before the blocking close, while still safely keeping the wrapper alive against a concurrent natural completion. - CancelAllRequests() waits on a condition variable signaled from erase() instead of polling in a sleep loop. HttpClientFactory now selects WinHTTP by default on Win32 desktop (non-WinRT) builds. Set MATSDK_USE_WININET=ON (CMake) or define HAVE_MAT_WININET_HTTP_CLIENT (legacy MSBuild) to opt back into WinInet, e.g. for IE-integrated proxy/cookie behavior. Both cpp files are always compiled; the choice is made at the factory's #include/#ifdef site, matching the existing pattern for WinRt vs. WinInet. Wired into both build systems: lib/CMakeLists.txt (new source files, winhttp link library, MATSDK_USE_WININET option) and lib/pal/desktop/desktop.vcxitems (new source files; linking uses #pragma comment(lib, "winhttp.lib") in the new .cpp so no individual .vcxproj's AdditionalDependencies needs updating). Validation (Windows x64 Debug, both CMake and the Solutions\MSTelemetrySDK.sln MSBuild path actually used by CI): - UnitTests: 496/496 passed. - FuncTests: 43/43 passed, excluding sendManyRequestsAndCancel, which hits the real production collector over the internet. That specific test hangs identically with the original, unmodified WinInet client under the same back-to-back test sequence, confirming it is pre-existing network/infrastructure flakiness unrelated to this change, not a regression. - Found and fixed two real bugs during validation: (1) WinHttpSetStatusCallback's return value was checked as a boolean, when it actually returns the previous callback function pointer (typically null on first registration) -- this rejected every request immediately after registering the callback; (2) the deadlock described above, reproduced live via a hung sendManyRequestsAndCancel run and confirmed fixed by comparing CPU-active vs. CPU-static process state before and after the shared_ptr change.

Their destruction order relative to LogManagerProvider::Release() and PAL::shutdown() (both called during process teardown) is unspecified, since PAL in particular is constructed lazily on first use rather than at a fixed point relative to these teardown calls. A downstream consumer (onnxruntime-genai, see https://github.com/microsoft/onnxruntime-genai/pull/2363) hit this in production as intermittent EXC_BAD_ACCESS crashes on macOS-arm64 at process exit: LogManagerFactory's registries and PAL's ISystemInformation shared_ptr member were sometimes already destroyed by the time teardown code tried to use them, and worked around it in their vendored copy of this SDK by leaking both singletons. Apply the same fix upstream: static T& x = *new T(); deliberately never destroys the object, so its members stay valid for the rest of the process regardless of teardown timing. Both objects are small and fixed-size (one per process), and PAL::shutdown() / Release() already perform the real resource teardown explicitly, so this only avoids the destructor-ordering hazard, not a resource leak in the ordinary sense.

That early return left m_flushPending == true and never posted m_flushComplete, so WaitForFlush() blocked forever and Shutdown() never completed. The race needs a flush to be pending when teardown starts, so it only reproduced when an earlier test had already pushed enough records to schedule an async flush -- which is why sendManyRequestsAndCancel hung in the full suite but passed in isolation. It was misread as WinHTTP cancellation not draining; the transport had already finished. Always release the waiters: cancel the pending handle, post the event, and clear the pending flag on the skipped path. Flush body moves to FlushImpl() so EndActivity() is paired with StartActivity() on exactly the path that acquired it. Verified on Windows: the doNothing/killIsTemporary/ sendManyRequestsAndCancel sequence that hung indefinitely now passes, 5/5 repeat runs are stable, functests are 43/43 and unittests 528/528.

On MSVC the CRT reports a constraint violation through the invalid parameter handler, whose default behaviour terminates the process via __fastfail (STATUS_STACK_BUFFER_OVERRUN / 0xC0000409) rather than returning EINVAL. This crashed AnnexKTests.memcpy_s in Debug builds, which Windows CI does run (test-win-latest.yml builds both Release and Debug). More importantly it was a latent abrupt-termination path in shipped Windows code: any caller passing count > destsz would kill the process instead of getting an error back. The delegate path also never zeroed the destination on error, contradicting the function's documented contract. Validate the arguments before copying on every platform so the documented "return EINVAL and zero the destination" behaviour holds uniformly. Also fix oneds_buffer_region_overlap, which used strict > against a one-past-the-last-byte address and so both missed genuine single-byte overlaps and mis-flagged merely adjacent buffers. Replaced with the standard half-open range test, with an explicit zero-length short circuit. Unit tests: 531/531 pass with no exclusions (previously the suite could not run AnnexKTests at all).

Cause: the test HTTP server writes responses from the reactor thread via ::send() with no SIGPIPE protection. That test deliberately cancels an upload that is still in flight against the /slow/ endpoint, so NSURLSession resets the connection while the server is mid-response. ::send() then fails with EPIPE and raises SIGPIPE; the test process installs no handler, so the default disposition terminates it. The race is timing-dependent, which is why it looks flaky and only shows up on the slower Apple CI runners. Fix (test infrastructure only, no SDK behavior change): - Add Socket::setNoSigPipe() and apply SO_NOSIGPIPE to every accepted connection (Apple/BSD, where the option is per-socket). - Pass MSG_NOSIGNAL from Socket::send() on Linux, which has no SO_NOSIGPIPE. Both make a write to a reset peer return EPIPE, which the reactor already handles by closing the connection.

WinHttpRequestWrapper::send() held m_requestsMutex across its entire body, including the synchronous-failure paths that call onRequestComplete(). onRequestComplete() invokes the application callback, which -- as the comment above that call already noted -- can synchronously tear down the client. That teardown reaches HttpClient_WinHttp::CancelAllRequests(), which waits on m_requestsCv. m_requestsMutex is a std::recursive_mutex and m_requestsCv is a std::condition_variable_any. condition_variable_any::wait() releases only ONE level of a recursive mutex, so waiting while the mutex was held twice left it locked. erase(), running on the WinHTTP callback thread, could then never acquire the mutex to remove the request and notify_all(), so the predicate never became true and the untimed wait never woke: a permanent lost-wakeup deadlock. The test provokes this by posting to closed port 127.0.0.1:1, which makes WinHttpSendRequest fail synchronously, and by setting CFG_INT_MAX_TEARDOWN_TIME = i % 2 so alternating iterations take the untimed full-shutdown wait. Split the handle-setup work into sendLocked(), which runs under the lock and only *reports* a synchronous failure, and send(), which completes the request via onRequestComplete() after the lock has been released. Cancellation is still serialized against setup, so a cancel cannot be lost mid-handle-creation. cancel() already called onRequestComplete() outside the lock and is unaffected.

Ensure every offline flush path releases waiters while graceful shutdown persists eligible records. Files: - lib/pal/TaskDispatcher.hpp, lib/pal/WorkerThread.cpp: serialize task lifetime and lock-safe destruction. - lib/offline/OfflineStorageHandler.cpp/.hpp: complete flush state and preserve shutdown data. - tests/unittests/PalTests.cpp, tests/unittests/OfflineStorageTests.cpp, tests/functests/BasicFuncTests.cpp: add regressions.

Make transport selection explicit in every build path. Files: - lib/http and lib/CMakeLists.txt: harden callback, cancellation, certificate, and drain lifetimes. - tests/unittests and tests/functests: cover reentrancy, redirect policy, certificate validation, and throwing completions. - UnitTests.vcxproj and FuncTests.vcxproj: compile tests against the selected backend and retain failure symbols.

Bound every test process, capture architecture-matched minidumps on hangs, and document the WinInet compatibility feature so cancellation regressions cannot consume an entire runner. Files: - .github/scripts and .github/workflows: add watchdog diagnostics and dual-transport matrices. - build-tests.cmd: select one transport and run all executables under deadlines. - docs/building-with-vcpkg.md and tests/vcpkg: document and validate the WinInet feature.

Add real bounded/full cancellation, process-lifetime libcurl initialization, orderly abort polling, and destroy-before-terminal callback ordering. Files: - lib/http/HttpClient_Curl.cpp/.hpp: add shared operation registry, callback accounting, cancellation epochs, and safe global/worker lifetime. - tests/unittests/HttpClientCurlTests.cpp: cover in-flight destruction, request deletion, peer/reentrant cancellation, cancel epochs, multiple clients, and callback ordering.

Preserve WinHTTP queries while stripping client-only fragments, retire failed Apple tasks, and make the cancellation timeout test clean up safely. Files changed: - lib/http/HttpClient_CAPI.cpp: defer handoff completions without lock inversion. - lib/http/HttpClient_WinHttp.cpp: parse dynamic URL components and sanitize request targets. - lib/http/HttpClient_Apple.mm: cancel unregistered suspended tasks. - tests/unittests: cover concurrent completion, query/fragment handling, and timeout cleanup.

Harden Android HTTP singleton lifetime and cancellation results; fail explicitly when the default client is unavailable. Validate batched disk records consistently, use writable session-test paths, and fix epoll and Android PAL JNI defects exposed by the full device run. Files changed: Android test bridge/configuration, HttpClient_Android, LogManagerImpl, OfflineStorageHandler, Android PAL, and related unit tests.
