http://d.puremagic.com/issues/show_bug.cgi?id=6116 Summary: May not join spawn()'ed threads Product: D Version: D2 Platform: x86_64 OS/Version: Linux Status: NEW Severity: major Priority: P2 Component: Phobos AssignedTo: nobody@puremagic.com ReportedBy: acehreli@yahoo.com --- Comment #0 from Ali Cehreli <acehreli@yahoo.com> 2011-06-06 16:33:09 PDT --- Version: 2.053 The command line: ~/dmd2.053/linux/bin64/dmd deneme.d -ofdeneme -unittest -J. -w Although I have multiple threads spawning each other here, I also had problems with just a single thread spawned from main. I wanted to keep this example as it exposes many different outputs for me. import std.stdio; import std.concurrency; import core.thread; void foo() { foreach (i; 0 .. 5) { Thread.sleep(dur!"msecs"(500)); writeln(i, " foo"); } } void intermediate3() { spawn(&foo); writeln("intermediate3 done"); } void intermediate2() { spawn(&intermediate3); writeln("intermediate2 done"); } void intermediate() { spawn(&intermediate2); writeln("intermediate done"); } void main() { spawn(&intermediate); writeln("main done"); } 1) ThreadException: $ time ./deneme main done intermediate done intermediate2 done intermediate3 done core.thread.ThreadException@src/core/thread.d(866): Unable to join thread ---------------- ---------------- real 0m0.003s user 0m0.000s sys 0m0.000s 2) No output from foo() (foo() is not joined) $ time ./deneme main done intermediate done intermediate2 done intermediate3 done real 0m0.003s user 0m0.000s sys 0m0.000s 3) Segmentation fault: $ time ./deneme main done intermediate done Segmentation fault real 0m0.003s user 0m0.000s sys 0m0.000s 4) Expected behavior: $ time ./deneme main done intermediate done intermediate2 done intermediate3 done 0 foo 1 foo 2 foo 3 foo 4 foo -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |

Posted in reply to Ali Cehreli | http://d.puremagic.com/issues/show_bug.cgi?id=6116 --- Comment #1 from Ali Cehreli <acehreli@yahoo.com> 2011-06-06 16:38:06 PDT --- Apparently I clipped the timings for the last run. When it joins successfully, the program takes long, seemingly waiting for the foo() thread: $ time ./deneme main done intermediate done intermediate2 done intermediate3 done 0 foo 1 foo 2 foo 3 foo 4 foo real 0m2.504s user 0m0.000s sys 0m0.000s -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |

The fix for this will likely be to add a status field where a thread may be marked as ready, starting, running, and terminated. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |
