…terrupted
Thread interrupts can be disabled after thread interrupter decided to
interrupt a thread but before thread actually receives and handles
a signal.
This may cause a data race accessing a Sample between profiler which
initializes and adds a Sample and the main thread using
Profiler::sample_block_buffer() in the profiler unit tests.
This is a possible fix for the following benign TSAN error:

This test has a few independent calls to asyncExpectThrows which uses asyncStart/asyncEnd. However, multiple top-level asyncStart/asyncEnd are not allowed, which causes the following flaky error: ``` Unhandled exception: Exception: Fatal: asyncStart() was called even though we are done with testing.. This is most likely a bug in your test. #0 asyncStart (package:expect/async_helper.dart:53) #1 asyncExpectThrows (package:expect/async_helper.dart:140) #2 testMalformedAuthenticateHeaderWithAuthHandler.<anonymous closure> (file:///b/s/w/ir/cache/builder/sdk/tests/standalone/io/http_auth_digest_test.dart:345) #3 Future._propagateToListeners.handleValueCallback (dart:async/future_impl.dart:951) #4 Future._propagateToListeners (dart:async/future_impl.dart:980) #5 Future._completeWithValue (dart:async/future_impl.dart:723) #6 Future._asyncCompleteWithValue.<anonymous closure> (dart:async/future_impl.dart:807) #7 _microtaskLoop (dart:async/schedule_microtask.dart:40) #8 _startMicrotaskLoop (dart:async/schedule_microtask.dart:49) #9 _runPendingImmediateCallback (dart:isolate-patch/isolate_patch.dart:128) #10 _RawReceivePort._handleMessage (dart:isolate-patch/isolate_patch.dart:195) --- Re-run this test: python3 tools/test.py -n vm-aot-ubsan-linux-release-x64 standalone/io/http_auth_digest_test ``` This change attempts to fix this by adding a top-level asyncStart/asyncEnd and also asyncStart/asyncEnd to the server start/shutdown to enclose each test case into asyncStart/asyncEnd and avoid printing "unittest-suite-success" marker before all test cases are finished.

Trying to build Dart after clean checkout from SVN gives me :
runtime/vm/dart_api_impl.cc: In function ‘void* dart::Dart_CreateIsolate(void*, void*)’:
runtime/vm/dart_api_impl.cc:38:71: error: declaration of ‘void* dart::Dart_CreateIsolate(void*, void*)’ with C language linkage
runtime/include/dart_api.h:185:26: error: conflicts with previous declaration ‘void* Dart_CreateIsolate(const Dart_Snapshot*, void*)’
I ended up changing the dart_api_impl.cc declaration to use const Dart_Snapshot* and did a cast to (void*) in order to call Dart::CreateIsolate((void*)snapshot, data);
The text was updated successfully, but these errors were encountered:
