Fixing this is not trivial, but it's certainly possible. You can avoid the crash by clipping (from, to) to legal buffer positions, but the right fix should be to completely re-validate from and to. The same bug happens when you call more than one before/after-change function. We should hold an extent (or two markers) over the changed region, and update FROM and TO as needed. I started to do this once, but I didn't understand code in insdel.c all that well, so the multiple-change stuff swamped me. I think I'll try again soon.

Basically, everything that I wanted to do make customize specifier friendly is done _except_ for the size stuff. (There needs to be a make-face-size function that calls frob-face-property along the lines of make-face-bold). After that it would be time to try to implement a real dynamic font model, but that is probably for 21.4 or so.. Jan

FAQ updated on the web site 24 years, 4 months

Sandra Wambold

Interested parties will be able to see that the XEmacs FAQ has now been updated on the web site. While the XEmacs FAQ is still woefully in need of change, what minor changes I have made are now available. Changes visible: * Content changes previously found in the CVS sources * the index.html is now index.convert, placing that page under genpage and giving it the "site look". * the Postscript versions of the FAQ have been removed. I'll probably put them back later (I don't feel like tangling with LaTeX tonight) * the many-part text version has been removed. I don't see much use for it. Priority now returns to updating the content since I have my update scheme worked out. -sew

21.2.24 Crashes! 24 years, 4 months

ShengHuo ZHU

When I run this code (a simplified version), XEmacs crashes. The problem is the text property. (defun test-decode (word) (let ((i -1) (s (substring word 0)) v) (while (< (incf i) (length s)) (if (eq (setq v (aref s i)) ? ) nil (aset s i (+ 128 v)))) s)) (let ((s "~{<:Ky2;S{#,NpJ)l6HK!#~}")) (put-text-property 0 (length s) 'face 'bold s) (setq s (test-decode s)) (decode-coding-string s 'cn-gb-2312)) -- Shenghuo

This discussion sounds familiar. And again, I disagree with your position. There are legitimate uses for changing the buffer from within the before-/after- change functions, and custom has demonstrated that. > We can fix the crash, but things like font-lock and setnu-mode, > which rely on having access to every change to operate correctly, > are still going to be screwed unless we disallow these changes. Neither font-lock nor setnu are very useful with things like Customize buffers. Maybe we should just say in the documentation that changing buffer text from after-change-functions is a bad idea for that kind of code.

Bold and Italic fonts 24 years, 4 months

claudia.yastremiz＠barclayscapital.com

Dear All, I have found that between XEmacs 20.4 and the new 21.whatever series (both in 21.1 and 21.2), both bold and italic fonts have stopped changing size when the font size is changed. I have searched the archives to see if this was discussed, but I only found a complain or two in the nt list but no explanation. The PROBLEMS file included in the distribution I have (the nt one) is out of date about the font menu (which now works) and makes no mention of size problems for italic or bold fonts. I have tested this mostly in the nt version (Fabrice Popineau's latest binary build, of a very slightly out of date 21.2, on nt4, both on SP3 and SP5). In this case, changing the size from the font Size submenu of the Options menu changes the "basic" (ie non-bold, non-italic) font but leaves bold and italic at 10pt, and the effect is the same if I try this from custom (whether I save it to the .emacs file or not). I have also looked at 21.1.3 (Acadia) on Unix (Solaris 2.6) using Exceed 6 as my X server on a pc, where I only tested changing the font size from the menu, and the behaviour seems to be that italics and bold are ALWAYS in 10 pt no matter what the size is when set from the Size submenu of the Options menu. In fact, I have it set to 18pt in my .emacs file (otherwise the letters are too small to read properly through Exceed), and the bold and italics come as 10pt as well on startup before I change anything. (I could not find a PROBLEMS file in this distribution, taken from the binary distros in xemacs.org, I think built by Charles Wilson). This does not happen in 20.4 (we have that still installed on another machine), where the bold and italic fonts rescale happily with the default when changed from the menu, and they come up happily in 18pt when I bring XEmacs up (it's using exactly the same .emacs file as the 21.1.3 version, since my home directory is mounted across), and the size changes uniformly down to 8pt with no problems. My .emacs file is a very slight variation on the sample.emacs file. So this seems to be generally broken, and the breakage to have happened between 20.4 and 21.something (and still be there in 21.2) unless, of course, the problem lies in the use of a pc running nt as the display, though I think Exceed has its own font set, so it would be a big coincidence if both the Exceed and the native NT versions had the same problem. Is nobody else seeing this? Any ideas on what I might be doing wrong, if anything? Or is this a true bug (I don't believe this is the intended behaviour)? Thanks, all the best, Claudia PS I asked Andy Piper and he suggested I forward this to the mailing list to see if anyone has any insight on the problem -------------------------------------------------------------------------------------- For more information about Barclays Capital, please visit our web site at http://www.barcap.com.

crash in call-process-internal 24 years, 4 months

Cotton Seed

I was doing M-! (shell-command) of: mv Tiger_FragmentTemplateMatch_RuleSet.C Tiger_FragmentMatch_RuleSet.C and xemacs with a failed assertion. It did not execute the mv command before the crash. I'm on redhat6.0. I am not able to reproduce the crash. - Cotton Fatal error: assertion failed, file lisp.h, line 969, RECORD_TYPEP (obj, &lrecord_string) Fatal error (6). Your files have been auto-saved. Use `M-x recover-session' to recover them. If you have access to the PROBLEMS file that came with your version of XEmacs, please check to see if your crash is described there, as there may be a workaround available. Otherwise, please report this bug by running the send-pr script included with XEmacs, or selecting `Send Bug Report' from the help menu. As a last resort send ordinary email to `crashes(a)xemacs.org'. *MAKE SURE* to include the information in the command M-x describe-installation. If at all possible, *please* try to obtain a C stack backtrace; it will help us immensely in determining what went wrong. To do this, locate the core file that was produced as a result of this crash (it's usually called `core' and is located in the directory in which you started the editor, or maybe in your home directory), and type gdb /usr/xemacs-21.2.23/bin/xemacs core then type `where' when the debugger prompt comes up.

Some people claim to not have the problem, though I wonder if thats really true or if they simply leave the fonts at 10 pts.... BTW, you need to test it with real bold and real italic fonts to see the problem. The three start-up buffers that cycle before you open any files is a good set of test buffers.
