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.

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.

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.

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. Room also caps its returned count at min(size, INT32_MAX); keying off < records.size() would treat that capped count as a failure and re-queue already-persisted records (duplicates). Key the re-queue off totalSaved == 0 instead, which is the true "nothing committed" signal. (The cap only matters for a batch larger than the RAM queue could ever hold.)

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.

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.

Reword the comment so the re-queue invariant is described correctly and future maintainers don't rely on the wrong contract. - TransmitProfiles::dump() logged a size_t rule index with %d, which is undefined behavior for printf-style varargs on 64-bit builds.

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.

If Join() had already run on the worker thread (its self-path detaches m_hThread), a later last-reference drop on that same thread would miss the self-check and delete the object while threadFunc was still executing below it -- the same UAF this change set fixes. Capture the worker's id in an atomic at threadFunc start and compare against that instead, so detection is correct regardless of detach ordering. Not reachable through current SDK code (the default WorkerThread is never explicitly Join()-ed), so this is defense-in-depth. Validated: ASAN dispatcher tests (PalTests incl WorkerThreadSelfDisposeOnOwnThreadIsSafe, TaskDispatcherCAPITests) all pass clean.

From d325700a1be70ad20cf4d67a921f700dc29dad85 Mon Sep 17 00:00:00 2001 From: Bhagirath Mehta Date: Sat, 1 Aug 2026 00:30:47 -0500 Subject: [PATCH 50/70] 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.

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.

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. Files changed: tests/common/SocketTools.hpp Validated locally on macOS (arm64, Debug): the test reproduced at ~30% (5/15 runs exited 141) before the fix and passed 30/30 after; the full FuncTests suite passes 40/40.
