Can't be used in AWS Lambda #51

Open yilinjuang opened 6 years ago

yilinjuang commented 6 years ago

When setting use_signal to False, it uses multiprocessing.Queue which isn't support in AWS Lambda. Are we gonna have other approach to not use signal? Maybe use multiprocessing.Pipe? Thanks

Good point. Do you want to make a PR for that?

yilinjuang commented 6 years ago

Sure. How about adding another argument other than use_signal? Or change the implementation inside use_signal?

can You provide a code snippet to test please

yilinjuang commented 6 years ago

@bitranox any lambda can reproduce the issue. Can refer to here and here for how to create one.

ok, I changed the implementation to use multiprocess.pipe (halfduplex). It is faster, more elegant and probably can work with AWS (let me know). See : https://github.com/bitranox/wrapt-timeout-decorator or https://github.com/pnpnpn/timeout-decorator/pull/53 yours sincerely Robert
