how to know what emacs is doing..

[lagarde]

Hello,

I changed my emacs version to GNU Emacs 22.0.91.1. Sometimes, my emacs process
uses the whole cpu and cant decrease. This behavior occures even if I edit a
text  and doesnt seem to result to a special command call.

So my question is to know if there is a way to know what emacs is currently
doing, and what are these most consuming threads.

thanks.

Well, very basic Emacs debugging is to (setq debug-on-error t) and then
hit C-g when it appears to freeze up.  That will show you the current
evaluation stack, which might be a little counterintuitive, but it does
in fact tell you what Emacs is doing.  Unless Emacs 23 has changed (and
I definitely would have expected to hear on this list) it's not
multithreaded at all.

It looks like you found this list via gmane; you should probably be
aware that it's the developers' list for the Gnus mail reader, which is
part of Emacs but not Emacs itself.  The broader Usenet gnu.emacs.help
newsgroup might be a better place for general Emacs questions.

He uses Emacs 22 (well, a pretest version thereof).  Emacs 23 won't be
multi-threaded as well.

aka gmane.emacs.help

Bye, Reiner.
