There are several problems that fork[pty] has, e.g. thatafter fork, interceptors are still active and this sometimes causescrashes or hangs. This is especially problematic for TSan, which usesinterceptors for OS-provided locks and mutexes, and even Libc functionsuse those.This patch replaces forkpty with posix_spawn on Darwin. Sinceposix_spawn doesn't fork (at least on Darwin), the interceptors are nota problem. Another benefit is that we'll handle post-fork failures (e.g.sandbox disallows "exec") gracefully now.Related revisions and previous attempts that were blocked by or had tobe revered due to test failures:https://reviews.llvm.org/D48451https://reviews.llvm.org/D40032Reviewed By: kubamracekDifferential Revision: https://reviews.llvm.org/D65253llvm-svn: 368947 List of files: /llvm-project-15.0.7/compiler-rt/test/asan/TestCases/Darwin/dladdr-demangling.cpp Thu, 15 Aug 2019 00:18:55 +0000 Julian Lettner <jlettner@apple.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/compiler-rt/test/asan/TestCases/Darwin/dladdr-demangling.cpp#673dc3d4 compiler-rt: Rename cc files below test/asan to cppSee r367803 and similar other changes.llvm-svn: 367887 List of files: /llvm-project-15.0.7/compiler-rt/test/asan/TestCases/Darwin/dladdr-demangling.cpp Mon, 05 Aug 2019 16:48:12 +0000 Nico Weber <nicolasweber@gmx.de>
