[Octave-bug-tracker] [bug #47299] lookfor without doc-cache extremely slow, many warnings

[John W. Eaton]

Follow-up Comment #2, bug #47299 (project octave):

The weirdness with warnings is apparently due to bugs with the way that the
warning state is handled when reset.  The lookfor function tries to set all
warnings off, then they are reset with unwind_protect.  I don't see warnings
if I do the following when I first start Octave:


more off
lookfor svd


but that takes a long time, and if I interrupt it (thus triggering the
unwind_protect block that attempts to reset the warning state) then try the
lookfor command again, then I start to see warnings.  If I interrupt again, I
continue to see warnings, but this time with stack trace info for each warning
that was not previously displayed.

I think we already have a bug report about warning state not being handled
correctly.
