Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The reproducer is supplied offline. Nested signals are not handled in the 
reproducer.

Also please note magic sleeps placed in both threads! Without them signals sent 
from main thread are lost.

Commit 216903
http://llvm.org/viewvc/llvm-project?view=revision&revision=216903
allows recursive interceptors.

I will also try to eliminate the need in sleep(1) in main.

The sleep in BusyThread still will be required. But it does not need to be a 
sleep, it can be any function intercepted by tsan (e.g. malloc or free), so I 
would expect it to not be a problem.

I've submitted
http://llvm.org/viewvc/llvm-project?view=revision&revision=217031
which should eliminate the need in sleep in the main thread.

Igor, I hope that this part of tasn now works for you.
If you have any other issues with tsan, feel free to file bug reports.
