Syntacticly significant whitespace? <wink> You’re sharp today, Stephen! Unfortunately, actually, for my purposes, it’s not. If you look in any DOC file and search for dontusethis-set-symbol-value-handler, the argument list looks like so: arguments: (VARIABLE HANDLER-TYPE HANDLER &optional HARG \ KEEP-EXISTING)) That is, there’s an extra right-parenthesis added after KEEP-EXISTING. I thought initially that this was a formatting quirk with d-s-s-v-h, and my experiment to see if this was the case made it into the commit when it shouldn’t have. It looks on closer examination as if it’s a bug in make-docfile.c. -- ¿Dónde estará ahora mi sobrino Yoghurtu Nghe, que tuvo que huir precipitadamente de la aldea por culpa de la escasez de rinocerontes? _______________________________________________ XEmacs-Patches mailing list XEmacs-Patches(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-patches

[COMMIT] Don't rely on GDB understanding the Lisp_Type_{Record, Char} enums 14 years, 10 months

Aidan Kehoe

APPROVE COMMIT NOTE: This patch has been committed. This has been biting me for a long time. The Right Thing to do would be to fix GDB instead, but I’m certainly not going to get to that, and as far as I can see we’re certainly not going to change these values within XEmacs. # HG changeset patch # User Aidan Kehoe <kehoea(a)parhasard.net> # Date 1244992102 -3600 # Node ID e9ccbc62f7e75ac885fb50bf5bcd65533791bc17 # Parent 48b45a6069619c377f5a212ff1d4ab6f19a94b64 Don't rely on GDB understanding the Lisp_Type_{Record,Char} enums, gdbinit.in 2009-06-14 Aidan Kehoe <kehoea(a)parhasard.net> * gdbinit.in: Supply variables for the Lisp_Type_Record, Lisp_Type_Char type information, for the sake of various versions of GDB that can't take them from the enum vals in the executable.

commit: Set buffer-file-coding-system more sensibly with zero-length files. 14 years, 10 months

The coding system value in question is set in #'insert-file-contents-internal like so: if (!NILP (used_codesys)) { Fset (used_codesys, XCODING_SYSTEM_NAME (coding_stream_detected_coding_system (XLSTREAM (stream)))); } It may be that coding_stream_detected_coding_system *should* never give undecided, even if no data have been seen, in which case the correct thing to do to fix this bug is to change coding_stream_detected_coding_system to do that. It may also be that undecided is a reasonable value there. It’s just not clear, and my patch as written is minimally invasive and fixes the issue. Your warning below risks having people think that autodetection succeeding means that the characters in the buffer reflect what whoever wrote the octets to disk meant them to mean, which is not true, our autodetection gets things wrong all the time. > If that logic is reasonable, then changing the comment above to "Some > buffers may remain 'undecided (eg, zero-length files).

It’s in progress, http://mid.gmane.org/18912.40510.593475.645687＠parhasard.net is the bones of it, but more work is needed, in particular implementing the checks for the Win32-specific coding systems and erroring in the appropriate places when data will be lost.
