emacs-cvs with jde using 100% processor [Solved]

[--D_S--]

Hi

This is somewat urgent. Since an update on saturday emacs is using all my processor when loading a java soucecode file, and still uses it after closing the java file. The strage part is it starts with jde but I was using it before.

On saturday I needed some space on my root so I emerge -uDN world, depcleaned and revdeprebuilded my system. I have reemerged everything I could think of but still.

Thanks.

I've also noticed that emacs-cvs-23 is a CPU resource hog. I'm not doing anything with JDE, so that probably isn't part of the problem. For now, I'm just running emacs with nice - so it still chews up huge chunks of cpu time, but not in a way that bothers much else. The stable (non cvs) emacs 21.4 seems to work fine and not be a cpu hog.

Hi

I'm using emacs-cvs-22.0.50-r3 and jde-2.3.5.1.

Emacs itself is now causing trouble the trouble is when I start jde by loading a java file emacs starts tu use all the processing power and slows down the system the worst is that the cpu heats to 55+ C degrees.

The trouble started after the update on saturday since then I have been working in the university.

I will report anything I find but for now I'll be working in the project if my cpu douesn't burn.

Thanks.

If beeing used emacs reduces the processor consumption but when idle it uses 100%.

already tried in text mode with X with other and new java files recompiling every jde version.

processor at 58C.

There are problems with JDE on emacs from cvs, and that includes the unicode branch. Try emacs-21 with jde.

Hi

I found out that jde was not the problem it's emacs when loading a java sourcecode file.

I unmerged jde to work with emacs' defaults and to my surprise it started the problem so it is a emacs problem.

Which is the best place to report this?

I can use emacs with auctex without problems also plain text files and c++ sourcecode.

The problem is mentioned here http://emacswiki.org/cgi-bin/wiki/XftGnuEmacs
The place for bugs is probably here http://lists.gnu.org/mailman/listinfo/emacs-pretest-bug

In particular, this change http://cedet.cvs.sourceforge.net/cedet/ ... 34&r2=1.35
Mentioned in this message http://lists.gnu.org/archive/html/emacs ... 00016.html
seems to fix the problem.

Simply edit the file /usr/share/emacs/site-lisp/cedet/semantic/semantic-idle.el according the the diff above, then...

Code: Select all

sudo emacs -nw -q
M-x byte-compile-file <ret> /usr/share/emacs/site-lisp/cedet/semantic/semantic-idle.el
C-x C-c

Then restart emacs as your normal user and it should be fine.

Thanks a lot now it works fine.

Is this still a problem with emacs-cvs (i.e. does semantic-idle.el still need to be patched manually)?

I've been thinking of going from emacs to emacs-cvs, but I still need to use JDE, and don't particularly want to keep two versions of emacs on my system.

Also, apart from gtk support, are there any other major advantages of emacs-cvs to normal emacs?

This was for emacs 22.0.50 but could be fixed with the above suggestions.

Emacs 22.0.92 is working fine and you can keep previous versions of emacs and use them by appending the version.
