can pwntools add the function of ignoring signal when debugging locally? #634

Closed skysider closed 8 years ago

skysider commented 8 years ago

Sometimes, the SIGALRM signal is annoying. I know that process of pwntools is based on subprocess, and subprocess has the function of ignoring signal by passing "preexec_fn" argument, So I wonder if it's possible to achieve it.

Yep, just pas in a preexec_fn that does what you want. We honor preexec_fn.

@zachriggle I see. I install pwntools by pip install pwntools, and the pwntools in pypi is updated on 2015.1, so I missed the feature.

In any case, if you're debugging locally, you can just tell GDB to ignore it.

Closing since the preexec_fn recommendation is a correct solution, and is now available in master.
