Komodo hangs while debugging Perl code using the threads module

jrheisey commented 8 years ago

Short Summary

Using breakpoints in functions which are executed in a thread context causes the target script and Komodo to hang or be unresponsive.

Steps to Reproduce

Test with the attached script
Set breakpoints at the print statement in each thread function.
Run the script under Komodo
It can take a second or two for the first break to occur in the ThreadOneSubroutine() function.
Click Go again.
Expected results

I would expect the two breakpoints to repeatedly be triggered every time I click Go in Komodo.

Actual results

This results in Komodo not responding or taking a long time to respond to its own UI events. The target script does not produce any output other than the first iteration in the ThreadOneSubroutine() function.

If you remove the breakpoints and click Go the script runs to completion as expected under Komodo.

Platform Information

Thanks for the detailed report. I cannot reproduce this on Linux. @cgchoffman can you reproduce this on Windows? What version of Perl do you have?

@mitchell-as I appear to get the same issue:

I open the file
Place break points at lines 11 and 18
press F5 to start debugger
It takes a while but the first breakpoint is hit
i press F5 or Go to continue
the second breakpoint is never hit and there is ton of errors in the logs

@jrheisey Please go to Edit > Preferences > Languages > Perl and then in the "Debugger Logging" section, check "Enable Debugger Log", and browse to/select a location you are familiar with. Then try again to debug. After experiencing the errors, please go to the debug log location you selected previously and send us that log. Thanks so much.

Sorry I left a couple breakpoints for another project in the previous upload. When these are gone I see the same behavior. perl-dbgp.log.txt pystderr.txt

Thanks! I'll have to look into this further when I get the chance.
