1763780 - Virtualized Console panel crash when generating a lot of logs

Status: RESOLVED WORKSFORME

(DevTools :: Console, defect)

Description

[Jan Honza Odvarko [:Honza] (always need-info? me)]

This might be an edge case (generating 1M logs), but the STRs might reveal a weak spot in the code base that's worth fixing. So, I am filing this anyway.

STR

1. Load http://janodvarko.cz/tests/bugzilla/1763780/
2. Open DevTools and select the Console panel
3. Generate 1M logs and wait till the Console panel crashes.

Are you still seeing this Honza? I tried a few times and even if it's slow, it eventually goes through and doesn't crash

I can't reproduce the crash either. It's extremely slow (comparing to Chrome), but also it's an extreme case.
Thank you for testing this, Nicolas!

Closing, since the original report isn't reproducible anymore.
