Bug with redefinition of register on ia64 architecture 18 years

Hans de Graaff

Hi, One of the currently open Gentoo bugs for XEmacs 21.4 has to do with the redefinition of register in src/lisp.h on ia64. I don't have access to this architecture so I can't check myself, but the bug report contains a good description of the problem: http://bugs.gentoo.org/show_bug.cgi?id=73366 I had a quick look in src/lisp.h myself, and I found it interesting to see that the code that is currently enabled is the DEBUG_XEMACS code. It seems that using the non-debug variant would solve this particular problem, but this may have other repercussions. It would be great if someone could have a look at this. Kind regards, Hans _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-beta

checking for fields 18 years

Ilya N. Golubev

Emacs version: 21.4a. Merged from emacs 21 to xemacs 21.5 with the same bug, so cross- posting there. `beginning-of-line' (in emacs only: another inconsistency of the merge), `forward-paragraph' and many other commands by default refuse to move across field boundaries. It is not even stated so in their docstings, for `forward-paragraph' at least. Other commands on top of them are also affected by that, and in an obscure way. Viper vi state `f' command operate within paragraph boundary as determined by `forward-paragraph' (which is also not documented), and if the boundary is before the end of line due to fields, then characters on that line are not found as expected. It actually happens with default settings of `shell-mode', if point is in shell prompt and character to find is in command being edited, which are different fields set up by `comint'. There is even no interactive commands to check for fields explicitly. All of the field limiting only overloads existing point movement commands. Some packages may set different faces for different fields, like `comint' does (using `comint-highlight-prompt' face), or may set nothing except fields themselves. It is entirely up to package. And even if face with different foreground color (or other visual attributes) is set, differences between it and text outside the field may be visible or not visible on particular display / terminal. (With xemacs `comint.el' after revision 1.14 of 2006/05/25 it is even more complex. `comint-highlight-prompt' is used only for `font-lock-face' extent property, so there is an additional unknown of whether font lock mode is on. It is also not typical use of font lock to denote otherwise hidden text areas across which regular editing commands will refuse to move, and thus required in this case. Normally it is used for syntax structures which may be easily recognized otherwise, across which editing commands move freely, and thus optional.) Generally user has to resort to evaluating elisp expressions to figure what is going on. Or, in emacs, work around it all by setting `inhibit-field-text-motion t' locally. Can not do so in xemacs due to bug in its comint. For these reasons considering lack of interactive commands to check for field boundaries a bug. These commands should do the same regardless of minor modes, faces attributes and display capabilities in particular emacs process. Explicit error messages about hitting field boundary would be even better. ** Why still report for emacs 21. Limiting movements to fields as described appeared in 21 release branch only, as 1999-10-17 Miles Bader <miles(a)gnu.org> change. If users could have noticed that and complained about that in that time, it would be reasonable now to recommend them just to switch to new development branch from release 21 one. But at that time emacs cvs was not publicly readable. Such a recommendation would be at best unreasonable. It signals that now it is <too late> to complain about release 21 bugs. Until 21 release, it was <too early> to do so. When there was time to do so, then?

Since 2006-10-28, someone has broken `Face-frob-property' 18 years

Nix

I just upgraded to latest CVS (2006-12-16, 21:20) to try to dig further into this KKCC-related (?) memory leak. (I'll know for sure if it's KKCC-related in an hour or so.) Instantly I had two new problems. The first was that all my comments were suddenly popping up in proportional fonts. The first two things I do to `font-lock-comment-face' are these: (make-face-italic 'font-lock-comment-face) (make-face-unbold 'font-lock-comment-face) and after the second, the face was changing drastically. (copy-face 'font-lock-comment-face 'foo-test-face) (face-font-name 'foo-test-face) "Bitstream Vera Sans Mono-11" (make-face-unbold 'foo-test-face) (face-font-name 'foo-test-face) "-*-lucidatypewriter-medium-o-*-*-*-120-*-*-*-*-*-*" What's going on? It becomes clearer if we look at the face's plists. Before: (cl-prettyprint (object-plist (get-face 'foo-test-face))) (foreground #<color-specifier global= [...] font #<font-specifier global=<unspecified> fallback=#<font-specifier global= (((x) .

What follows is a C stack backtrace and then a Lisp backtrace. I don't think --with-xim works on Solaris. Last time I tried, I couldn't even build that way. HTH, Vin PS.

Re: Sound Support on Solaris with 21.4.20; Was: [Success with a little effort] XEmacs 21.4.19 18 years

Mike Kupfer

A couple years ago (!) someone gave me a patch that uses the current (post-SUNWaudmo) native Solaris audio API. It works fine on SPARC but not on x86 boxes. I suspect it's a byte-ordering issue, but I haven't had time to look at it. I hope to get to it next year, after I've updated the XEmacs MH-E and gnus packages. Once I've got it working on both platforms, I'll submit a patch. cheers, mike _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-beta

Name of ocaml package 18 years

Hans de Graaff

Hi, Is there a specific reason that the ocaml package is called 'ocaml' and not 'ocaml-mode'? The latter seems to be more consistent with other similar packages such as ruby-mode and perl-mode. I got triggered about this by a Gentoo feature request to rename the package: http://bugs.gentoo.org/show_bug.cgi?id=156943 I'd rather follow XEmacs package names, but I think the suggestion to rename the package makes sense.

Patches for ruby-modes 18 years

Hans de Graaff

A few weeks ago I sent a rather large patch to the patches mailing list for ruby-modes. The patch basically brought ruby-modes up to date with the versions distributed with the ruby package itself. I've seen no feedback on this patch, so now I'm wondering if I should just be patient or if additional action is needed to move this patch towards CVS. If action is needed it would be useful to know what to do. Kind regards, Hans _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-beta
