ggtags frozen emacs for several seconds
mtellezj opened this issue · comments
I have emacs frozen at random intervals (2-10 minutes between intervals) when I'm doing basic python editing. the cpu fan start to spinnig very fast and top show me that emacs is using 100% cpu. I ran profiler and I get this:

Now I disable elpy and company but without luck. Any help?
I think ggtags-fontify-code
is triggered by eldoc-mode
. More specifically it looks like font-locking python in a temp buffer has issues. Somehow python-info-docstring-p
is very expensive there.
Hi, thanks for the reply. I disable eldoc-mod
and everything is running smooth. Should I open a bug on eldoc
or this is ggtags
realted?
@mtellezj Neither. I think this is likely an issue with python-mode
but I am clueless since I don't use python and the emacs mode I use is from many years ago.
Thanks a lot. I'll check with python mode.
