The following issue has been SUBMITTED. ====================================================================== http://cmake.org/Bug/view.php?id=14303 ====================================================================== Reported By: Rolf Eike Beer Assigned To: Rolf Eike Beer ====================================================================== Project: CMake Issue ID: 14303 Category: CTest Reproducibility: random Severity: block Priority: normal Status: assigned Target Version: CMake 2.8.12 ====================================================================== Date Submitted: 2013-07-23 02:23 EDT Last Modified: 2013-07-23 02:23 EDT ====================================================================== Summary: Parallel memtest broken Description: Short version: memory checker output is redirected to a file, which will be the same for every test, even parallel ones. This has been broken forever. Valgrind is not affected in currently released versions because it did not redirect output to file there (which caused other issues), but in current master it does.
Details: The filename is generated as: this->MemoryTesterOutputFile = this->CTest->GetBinaryDir() + "/Testing/Temporary/MemoryChecker.log"; The simple (but correct) solution would be to include the test index into the filename, as that is guaranteed to be unique and to work on all filesystems as it is an ordinary integer. Sadly I have not yet found a way to access this index or anything that has it from within cmCTestMemCheckHandler::InitializeMemoryChecking(). Valgrind was switched to use the output files in dde6306. Since then running a parallel memcheck will happily screw the results, which is why I have noticed this at all in the first place. Sadly we have no testcase that would catch this, I only found it by manually inspecting the memchecker logs an noticing mixed results. ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2013-07-23 02:23 Rolf Eike Beer New Issue 2013-07-23 02:23 Rolf Eike Beer Status new => assigned 2013-07-23 02:23 Rolf Eike Beer Assigned To => Rolf Eike Beer ====================================================================== -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
