extension not finding passwords and leaving processes with "[browserpass-lin] <defunct>"

[pniederlag]

browserpass zombies

After a recent update I noticed a very laggy behaviour of the browserpass-extension. When looking into the details I found that procecsses pile up in my processlist

[browserpass-lin] <defunct>

This happens quite frequently while sometimes the list of passwords just works as intented. No pattern that makes the difference betwenn "creates zombie" and "works as intented" found yet. When a password is found no zombie process shows up. Once a password is found future lookups tend to work until the browser is restarted.

Thanks for the report! I'm wondering if this could be explained (and solved) by #342, have you seen that thread by any chance?

[pniederlag]

Thx for your feedback, actually yes, I was thinking about it but forgot to link it.

I tested a local build on master with merged branch "hide-badge" (which #342 refers to), zombie-processes don't show up anymore.

So my problem is currently solved, thx. Probably would make sense to ship an update 3.8.1 ?

[maximbaz]

Thanks for confirming! Yeah we should get that merged...

unfortunatly <defunct> processes again show up after a long working day, but in a very low number (< 10). I think I haven't seen this behaviour until recently. So I wonder, what has been changed? and, where?

[maximbaz]

I'm not sure! If you manage to discover any way to reproduce this, please share... I have a little doubt that a browser extension can somehow control processes that browser starts 🤔

[maximbaz]

Does it ever happen that you cancel an operation? You open popup but close it before list is rendered, or you ask browserpass to fill out a form but don't complete the operation (e.g. by not touching yubikey to confirm, if you are using one)?

Hi @maximbaz the problem really sticks around without me having a clue... could be memory or timinig issues ;(
