Data races are one of the most common and hardest to debug types of bugs in concurrent systems. A data race occurs when two threads access the same variable concurrently and at least one of the accesses is write. ThreadSanitizer is part of clang 3. To build the freshest version see ThreadSanitizerDevelopment page. This list is last updated on Dec and is related to clang compiler, see up-to-date list here.

Data tsan occur when multiple threads access the same memory without synchronization tsan at least one access is a write. Data races are dangerous because they can cause programs to behave unpredictably, or even result in memory corruption. The Thread Sanitizer records tsaan information about each memory access, and checks whether that access participates in a race. All memory accesses in the code is transformed by the tsan in the following way:. Each thread stores its own timestamp and the timestamps for other threads in order to establish points of synchronization.

ThreadSanitizer v2 is a synchronization error detector based on compiler instrumentation. It is also capable of detecting other threading errors like deadlocks, unjoined threads, destroying locked mutexes, use of async-signal unsafe code in signal как сообщается здесь, and others.
You may have heard of the old Valgrind-based version of Tsan, but TSan v2 has tsan brand new state machine and has nothing to do with Valgrind. The old ThreadSanitizer is deprecated больше информации Chromium. Enter these variables tsan the resulting editor: Some tests waiting for child processes may fail with such tsan big timeout.
Note 2: Note 3: Note 4: Setting them is optional in most cases, but may help if you're seeing strange reports in the library code:. Note 5: As of Novemberthe commands above don't symbolize the stack trace. Pipe the output through the ASAN symbolize script, e. Unlike Valgrind, ThreadSanitizer v2 doesn't support gtest filter files.
ThreadSanitizer data race report contains two or more stack traces of conflicting memory accesses the topmost access is the last one together with the thread IDs and the acquired mutexes.
For a tsan variable involved its name is printed, stack or heap memory locations are described using http://e-computer-security.info/enjoying-group-sex-at-halol-highway-in-scrap-yard-whatsapp-1507264-4005.php allocation stack trace.
Write of size tsan at 0x7f8a8f1d99ec by thread T ParseLazy v Previous write of size 4 at 0x7f8a8f1d99ec by thread T8: Tsan is global 'v The pattern is matched against: Good suppressions match a single race report or a number of reports with a common root causetsan are unlikely to mask further races in other components.
A suppression must be preceded by a comment started with a " " with a crbug link. Examples of good suppressions for the above race report: Suppresses other tsan in zone-inl.
You can also suppress globals. Ok, but won't tsan calls to zone from other places. Watch out - may match other functions called "New". Function arguments may change over time, better omit them. Too generic. The possible suppression prefixes are: Reproducing race reports in tests Before trying to reproduce a race report in a Chromium test, make sure they are not suppressed or ignored.
If the race report matches a line in the suppressions file, TSan does not жмите that адрес. If the function name matches a "fun: If the source file name matches an "src: Note that the tests do not depend on ignores.
You can't execute an instrumented binary from GDB, because it maps something in tsan place where TSan needs to map tsan shadow: ThreadSanitizer is suspended at startup pid ThreadSanitizer v2 is only supported on Linux so far. Setting them is optional in most cases, but may help if you're seeing strange reports in the library code: When applicable, the stack traces of thread creations and как сообщается здесь acquisitions are also listed.
