https://d.puremagic.com/issues/show_bug.cgi?id=11803 Summary: DMD tester core.exception.AssertError@core.thread(26XX): unittest failure Product: D Version: unspecified Platform: All OS/Version: All Status: NEW Severity: normal Priority: P2 Component: druntime AssignedTo: nobody@puremagic.com ReportedBy: maxim@maxim-fomin.ru --- Comment #0 from Maxim Fomin <maxim@maxim-fomin.ru> 2013-12-22 11:20:31 PST --- This is similar to issue 8960: from core/thread.d:2637 unittest { import core.sync.semaphore; shared bool inCriticalRegion; auto sem = new Semaphore(); auto thr = new Thread( { thread_enterCriticalRegion(); inCriticalRegion = true; sem.notify(); Thread.sleep(dur!"msecs"(1)); inCriticalRegion = false; thread_exitCriticalRegion(); }); thr.start(); sem.wait(); assert(inCriticalRegion); thread_suspendAll(); assert(!inCriticalRegion); thread_resumeAll(); } Started thread may terminate before executing se,.wait() thus leaving inCriticalSection = false. The root of the problem is absence of supporting code to launch thread and wait for a semaphore. This makes current unittest to speculate whether thread will terminate before waiting semaphore or not. Example of non-deterministic failure: d.puremagic.com/test-results/pull.ghtml?projectid=1&runid=829992&logid=5 -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |
