*previous page* broken 24 years, 2 months

Neal D. Becker

Viewing a multi-page article, there seems to be no way to page back. Going to the bold text saying "previous page", neither hitting return nor clicking button2 works. Both are bound to insert text, giving the message that the buffer is read-only. I'm sure this used to work with earlier xemacs/gnus. Gnus v5.8.7 XEmacs 21.1 (patch 12) "Channel Islands" [Lucid] (i686-pc-linux) of Mon Sep 11 2000 on adglinux1.hns.com 200 hnssysb.hns.com InterNetNews NNRP server INN 1.5.1 17-Dec-1996 ready (posting ok).

[CRASH] in -nw mode / image specifiers 24 years, 2 months

Didier Verna

This is under debian woody, latest CVS version. ,---- | - Start XEmacs (21.2) in no-window mode. | - Do: (set-face-background-pixmap 'default "a/path/to/a/pixmap/file") | - Do: C-x 2 (split-window) `----- For me, it crashes immediately. The concerned face-property is the following: #<image-specifier global=((tty) . [string :data "~/share/images/tile/marble.xpm"]) 0x1c8> which looks really bizarre to me. Here the C stacktrace that I get (after a core dump, I can't run "XEmacs -nw" within gdb). What I don't understand is that XEmacs is calling text_query_geometry on the *pixmap file name*. This sounds like a completely bogus image specifier behavior to me, but maybe I'm wrong. I'm not familiar at all with the specifier code, so I can't debug this. Any ideas are welcome.

I appearantly can't do that on my linux box. gdb complains that it "Cannot access memory at address 0x40016e08" as soon as I try to run xemacs within it. BTW, I have other weird problems from time to time, like once in a while a core produced by XEmacs is in "unreadable format" for gdb, I don't know why. These strange problems have only occured on linux in my experience. -- / / _ _ Didier Verna http://www.inf.enst.fr/~verna/ - / / - / / /_/ / EPITA / LRDE mailto:didier＠lrde.epita.fr /_/ / /_/ / /__ / 14-16 rue Voltaire Tel. +33 (1) 53 14 59 47 94276 Kremlin-Bicêtre cedex Fax. +33 (1) 44 08 01 99

Further to this, the face changes are made by `initialize-custom-faces'. This is called from `custom-initialize-frame', because the global frame properties don't match the new frame properties. These values come from `get-custom-frame-properties', with the global properties already being cached in `default-custom-frame-properties'. The value in there, incidentally, has `light' as the background. Daniel -- Trust the art, not the artist. -- Bruce Springsteen

It's displayed in right faces. Not in my case. I still see the same effects. I end up with the font-lock-comment-face being cyan in the second frame, while it's green in the first frame.

I think that the big issue is that the software continues to adapt itself to the default background color, despite my telling explicitly what I want. I think that if I only set the default face, having XEmacs change the rest of it's faces to something readable is nice. When I explicitly set the face properties, I would expect them to stay, even if that's unreadable. Daniel -- We fear that pop-culture is the only culture we're ever going to have.

CORE on close-buffer 24 years, 2 months

Norbert Koch

Hi! XEmacs 21.2 (beta36) "Notus" [Lucid] (i386-unknown-freebsd3.3) of Tue Oct 10 2000 on lamia.LF.net I was copying a section from a file-buffer into a Gnus article. After closing the file-buffer, xemacs closed on me... with the following C-stack, no Lisp-backtrace besides the abort-trap I saw the same behaviour some days ago. I guess, it's a GC issue, because of (gdb) up 5 #5 0x80c1499 in error (fmt=0x8298960 "Marker does not point #anywhere") at eval.c:2052 2052 RETURN_UNGCPRO (signal_1 (error_symbol, data)); But perhaps the corrupt marker is the culprit in the first place. #0 0x184e23d0 in kill () from /usr/lib/libc.so.3 #1 0x80ba5c3 in fatal_error_signal (sig=6) at emacs.c:531 #2 0xbfbfdfdc in ??
