Re: [crash] redisplay after widening 26 years, 2 months

Gunnar Evermann

I have now gotten a bit closer to fixing the redisplay bug related to widening. As mentioned earlier the problem is that the redisplay start-marker is not set correctly and that the line start cache contains a bogus entry (this actually causes the crash in 21.0). The problem is to detect in redisplay if this situation occurs. One approach that works in some cases is to rely on the start_at_line_beg member of the window structure. When this is true and we are not at the line beginning we have to readjust the marker. The problem with this approach is that 'start_at_line_beg' is not always set correctly. The appended patch partially corrects this. We still lose if start is not at the beginning of a line before widening. Unless I have missed something this is only supposed to happen with long wrapped lines. In this case we seem to produce bogus line_start_cache entries anyway (unrelated to narrowing/widening). I need to look at this more closely. Also I have to check where start_at _line_beg gets clobbered. I guess we could put this patch in 21.0 if some redisplay-experts agree, after all it fixes Collin's reproduction recipe, but it's still possible to get crashes after some scrolling. For 21.2 I plan to examine in more detail in which cases startp is allowed to be in the middle of a line and what to enter in the cache then. Helpful comments are always appreciated.

Re: Not for 21.0: mswindows font selection dialog 26 years, 2 months

Note that Irish Goat contains patches by me to this for the X version. I tried making the interface funtion 'custom-set-face-update-spec' as general as possible so it should work for you. Jan

Or is Armageddon gone totally now? Because most of Armageddon checks were wrong. I see no reason why XEmacs should be completely hosed (ignoring hooks is what I call hosed) when exiting. As an example: there used to be code in save_excursion_save() that simply ignored the whole save-excursion if preparing_for_armageddon.

The chicken or the egg? -or- Tastes great or less filling? 26 years, 2 months

SL Baur

I'm going to be making an intermediate package update tomorrow/later today. Please do at least some rudimentary testing of it. For release it is my intention to rebytecompile and repackage all the packaged lisp prior to having someone cons up the SUMO tarball (the ancient Gnus 5.4 package dies, there is no reason to keep it around any more). If there are any dissenting opinions that this isn't the Right Thing to do, please let me know now. Thanks. I expect to have core distribution tarballs and preliminary lisp package tarballs out sometime before midnight and after some testing make the 'net announcement sometime later this week depending upon further input from Jason.

I got my first pgcc/egcs-related crash with 1.1a. Turn down the optimization. I had to add the now-familiar pgcc flags `-fno-risc -fno-peep-spills'. I think these are named something different in pure egcs.

Release it now - but make people aware that 20.4 is more stable and 21.1 will be released soon. The quality is a lot higher than some FSF major releases I've used in the past. I think we should do binary kits as well. andy
