I can verify that the one with the dead processes is fixed by your patch which checks for dead processes. The other type of crash during using lookup.el was the one which crashed after `split-window', shortly after inserting Japanese. This was extremely annoying, as it was very frequent. Last Sunday I was finally able to reproduce it, but it was very late and I was to stupid to narrow it down small bit of sample code. After applying your patch it went away. I tried it on Linux and Solaris 2.5 and lookup.el hasn't crashed since. > > The last function shown on the lisp backtraces was always > > `split-window' shortly after some Japanese characters had been > > inserted. > > > > Therefore when I saw Gunnars patch appear on this list, I guessed this > > might fix my problem, and indeed it did. > > Uhm, it wasn't really meant as a serious patch, more as a help in > diagnosing the problem.

Can I help to measure the slowdown somehow? What sort of thing should be measured? Mike

Oh, are these the crashes you reported to crashes(a)xemacs.org (Sorry don't have the PR# handy)?

Uhm, it wasn't really meant as a serious patch, more as a help in diagnosing the problem. As you are apparently running an xemacs with it, does it cause a massive slowdown or any other obvious changes? Gunnar

It's been a part of NAS (or some very old patch for NAS, that was never incorporated) for quite a while; you just had to know what option to use to enable it. I've been using that for several years now. Ray

Wonderful! This cures the frequent crashes I experienced while using lookup.el. Last weekend I managed to reproduce these crashes, but wasn't yet able to narrow it down to a small bit of sample code. The last function shown on the lisp backtraces was always `split-window' shortly after some Japanese characters had been inserted. Therefore when I saw Gunnars patch appear on this list, I guessed this might fix my problem, and indeed it did. Thank you very much! Mike

Latest tabs changes leave XEmacs completely broken. 25 years, 1 month

Martin Buchholz

Beta testers, please do not update to the latest version from CVS. When I start up the latest XEmacs from CVS, a black frame is on the screen for 20 seconds or so, and then it crashes. It seems very likely that Andy's changes of today caused the problem. Andy, could you back out your change if you can't figure out what's going on fairly quickly, so that people can at least use CVS? gdb gives an enormous backtrace with thousands of stack frames that starts like this: #0 TabLayout (tw=0x855c750, wid=91, hgt=23, reply_height=0x0, query_only=0) at /xemacs/ws/dev/lwlib/xlwtabs.c:1676 #1 0x81eec8d in TabsResize (w=0x855c750) at /xemacs/ws/dev/lwlib/xlwtabs.c:545 #2 0x81eee17 in TabsExpose (w=0x855c750, event=0x0, region=0x0) at /xemacs/ws/dev/lwlib/xlwtabs.c:591 #3 0x81eedd8 in TabsResize (w=0x855c750) at /xemacs/ws/dev/lwlib/xlwtabs.c:573 #4 0x81eee17 in TabsExpose (w=0x855c750, event=0x0, region=0x0) at /xemacs/ws/dev/lwlib/xlwtabs.c:591 #5 0x81eedd8 in TabsResize (w=0x855c750) at /xemacs/ws/dev/lwlib/xlwtabs.c:573 #6 0x81eee17 in TabsExpose (w=0x855c750, event=0x0, region=0x0) at /xemacs/ws/dev/lwlib/xlwtabs.c:591 #7 0x81eedd8 in TabsResize (w=0x855c750) at /xemacs/ws/dev/lwlib/xlwtabs.c:573 #8 0x81eee17 in TabsExpose (w=0x855c750, event=0x0, region=0x0) at /xemacs/ws/dev/lwlib/xlwtabs.c:591 #9 0x81eedd8 in TabsResize (w=0x855c750) at /xemacs/ws/dev/lwlib/xlwtabs.c:573 #10 0x81eee17 in TabsExpose (w=0x855c750, event=0x0, region=0x0) at /xemacs/ws/dev/lwlib/xlwtabs.c:591 #11 0x81eedd8 in TabsResize (w=0x855c750) at /xemacs/ws/dev/lwlib/xlwtabs.c:573 #12 0x81eee17 in TabsExpose (w=0x855c750, event=0x0, region=0x0) at /xemacs/ws/dev/lwlib/xlwtabs.c:591 #13 0x81eedd8 in TabsResize (w=0x855c750) at /xemacs/ws/dev/lwlib/xlwtabs.c:573 #14 0x81eee17 in TabsExpose (w=0x855c750, event=0x0, region=0x0) at /xemacs/ws/dev/lwlib/xlwtabs.c:591 #15 0x81eedd8 in TabsResize (w=0x855c750) at /xemacs/ws/dev/lwlib/xlwtabs.c:573 #16 0x81eee17 in TabsExpose (w=0x855c750, event=0x0, region=0x0) at /xemacs/ws/dev/lwlib/xlwtabs.c:591 #17 0x81eedd8 in TabsResize (w=0x855c750) at /xemacs/ws/dev/lwlib/xlwtabs.c:573 Martin

Another tabs fix 25 years, 1 month

Andy Piper

Ed, The tabs do not pick up changed fonts when done via XtSetValues, this is because the GCs need to be recalculated. This patch fixes this (although doesn't explain why I still can't get font setting to work properly). andy 1999-12-14 Andy Piper <andy(a)xemacs.org> * xlwtabs.c (TabsSetValues): re-allocate GCs if font has changed. -------------------------------------------------------------- Dr Andy Piper Senior Consultant Architect, BEA Systems Ltd

Is it ok to release packages? 25 years, 1 month

Andreas Jaeger

I didn't follow all discussions on the xemacs list closely - but I didn't get any real bug report regarding the packages. Is there any showstopper? If I don't hear anything I'm releasing the packages tonight (local time). If anybody finds a problem with any package after the release, I can release a new version soon.
