Building Cedet 1.0 with XE 21.4.22 gives a segfault 13 years, 11 months

Johann 'Myrkraverk' Oskarsson

Hi all, While trying to build Cedet 1.0 with XE 21.4.22 I came across this. I do hope Gmail does not munge the console output below too much. johann＠asuka:..acs/cedet-1.0% /opt/myrkraverk/xemacs-21.4.22/bin/xemacs -q -l cedet-build.el -f cedet-build -batch zsh: segmentation fault /opt/myrkraverk/xemacs-21.4.22/bin/xemacs -q -l cedet-build.el -f cedet-build While I know there are some issues with compiling Cedet with XE I do believe a segfault is a problem with XE rather than Cedet itself. This is a self-compiled XE: johann＠asuka:..acs/cedet-1.0% uname -a Linux asuka 2.6.32-27-generic #49-Ubuntu SMP Wed Dec 1 23:52:12 UTC 2010 i686 GNU/Linux johann＠asuka:..acs/cedet-1.0% gcc --version gcc (Ubuntu 4.4.3-4ubuntu5) 4.4.3 Copyright (C) 2009 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. I believe there is a way to compile Cedet manually. What is involved with that?

BUG: regexp-opt fails when loading jde-imenu in XEmacs 21.4.22 13 years, 11 months

Steve Carney

I installed XEmacs 21.4 (patch 22) on Windows XP and ran into a regexp-opt problem when loading jde-imenu. jde-imenu has: (defconst jde-imenu-valid-modifiers-regexp (concat "\\b" (regexp-opt (mapcar #'car jde-imenu-default-modifier-abbrev-alist) t) "\\b") "Regexp of valid Java modifiers used by `jde-imenu-modifier-field-validate'.") jde-imenu fails to load due to a bug in regexp-opt. In the above defconst, the mapcar form evaluates to: ("public" "protected" "private" "static" "transient" "volatile" "abstract" "final" "native" "synchronized" "strictfp") and the above regexp-opt form produces error (with backtrace): Debugger entered--Lisp error: (wrong-type-argument characterp "abstract") concat(("abstract")) (list (concat (nreverse ...))) (lambda (s) (list (concat ...)))("abstract") mapcar((lambda (s) (list (concat ...))) ("abstract" "final" "native" "private" "protected" "public" "static" "strictfp" "synchronized" "transient" "volatile")) (let* ((sgnirts ...) (xiffus ...)) (if (> ... 0) (let* ... ...) (let* ... ...))) (if (> (length prefix) 0) (let* (... ...) (concat open-group ... ... close-group)) (let* (... ...) (if ... ... ...))) (let ((prefix ...)) (if (> ... 0) (let* ... ...) (let* ... ...))) (cond ((= ... 0) "") ((= ... 1) (if ... ... ...)) ((= ... 0) (concat open-charset ... "?" close-charset)) ((and ... ...) (let ... ... ...)) (t (let ... ...))) (let* ((open-group ...)

(t ...))) regexp-opt-group(("abstract" "final" "native" "private" "protected" "public" "static" "strictfp" "synchronized" "transient" "volatile") "\\(") (let* ((max-lisp-eval-depth ...) (max-specpdl-size ...) (completion-ignore-case nil) (completion-regexp-list nil) (words ...) (open ...) (sorted-strings ...) (re ...)) (if words (concat "\\<" re "\\>") re)) (progn (let* (... ... ... ... ... ... ... ...) (if words ... re))) (unwind-protect (progn (let* ... ...)) (store-match-data match-data)) (let ((match-data ...)) (unwind-protect (progn ...) (store-match-data match-data))) (save-match-data (let* (... ... ... ... ... ... ... ...) (if words ... re))) regexp-opt(("public" "protected" "private" "static" "transient" "volatile" "abstract" "final" "native" "synchronized" "strictfp") t) eval((regexp-opt (mapcar (function car) jde-imenu-default-modifier-abbrev-alist) t)) eval-interactive((regexp-opt (mapcar (function car) jde-imenu-default-modifier-abbrev-alist) t)) eval-last-sexp((4)) call-interactively(eval-last-sexp) Replacing regexp-opt.el with the file from XEmacs 21.4.21 fixes the problem.

Looking around again I found a ChangeLog entry where netbsd.h is said to be completely rewitten by Martin Buchholz 1997-06-04.

[a curiosity] XEmacs frame is decorated differently 13 years, 11 months

Giacomo Boffi

new window managers (in my case compiz) don't like to draw frames and buttons around the individual windows, this job being delegated to a window decorator (in my case emerald) i have setup emerald so that it draws only a light shadow SE of each window, and everithing is fine except XEmacs windows, that get a much darker shadow in the attached .png, you'll see an xterm window above, with the light shadow cast un the root window and on the underlying XEmacs window, and an XEmacs window below, with its much darker shadow cast on the root window i can live with the darker shadow, even if it is slightly annoying, but i'd like to know the reason of this strange behaviour thanks in advance, ciao -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. -- . _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://lists.xemacs.org/mailman/listinfo/xemacs-beta

21.4 and 21.5 can't edebug a function while GNU emacs can. 13 years, 11 months

Uwe Brauer

Hello I cannot edebug the following function (defun matlab-shell-render-html-anchor (str) "Render html anchors inserted into the MATLAB shell buffer. Argument STR is the text for the anchor." (if (string-match matlab-anchor-end str) (save-excursion (while (re-search-backward matlab-anchor-beg nil t) (let* ((anchor-beg-start (match-beginning 0)) (anchor-beg-finish (match-end 0)) (anchor-text (match-string 1)) (anchor-end-finish (search-forward matlab-anchor-end)) (anchor-end-start (match-beginning 0)) (o (matlab-make-overlay anchor-beg-finish anchor-end-start))) (matlab-overlay-put o 'mouse-face 'highlight) (matlab-overlay-put o 'face 'underline) (matlab-overlay-put o 'matlab-url anchor-text) (matlab-overlay-put o 'keymap matlab-shell-html-map) (delete-region anchor-end-start anchor-end-finish) (delete-region anchor-beg-start anchor-beg-finish) )))) ) When I do the cursor (with arrow jumps directly to the if line) Like (defun matlab-shell-render-html-anchor (str) "Render html anchors inserted into the MATLAB shell buffer. Argument STR is the text for the anchor." =>f (string-match matlab-anchor-end str) (save-excursion (while (re-search-backward matlab-anchor-beg nil t) (let* ((anchor-beg-start (match-beginning 0)) (anchor-beg-finish (match-end 0)) (anchor-text (match-string 1)) (anchor-end-finish (search-forward matlab-anchor-end)) (anchor-end-start (match-beginning 0)) (o (matlab-make-overlay anchor-beg-finish anchor-end-start))) (matlab-overlay-put o 'mouse-face 'highlight) (matlab-overlay-put o 'face 'underline) (matlab-overlay-put o 'matlab-url anchor-text) (matlab-overlay-put o 'keymap matlab-shell-html-map) (delete-region anchor-end-start anchor-end-finish) (delete-region anchor-beg-start anchor-beg-finish) )))) ) I don't understand this. For other functions in the matlab pkg edebug behaves as expected.

Where to upload? 13 years, 11 months

steven Mitchell

Hello, My son and I wrote some code for Xemacs and while it is useful to us and adds to our user experience--and we want to share, I don't think it is enough to make a package out of it. Do all things need to be made into packages to b e distributed? Is that what I should do? Or, where do you think things like this should get uploaded to? I don't have a personal website to upload it to.

GPLv3|L8R -- Remaining files one by one: "src/s/freebsd.h" 13 years, 11 months

The XEmacs Package Smoketest

Hi, This time I look at the "src/s/freebsd.h" and friends. That is "src/s/freebsd.h", "src/s/irix6-0.h", "src/s/netbsd.h" and "src/s/sol2.h". All of these header files except sol2.h contains the comment "Synched up with: FSF 19.31." which has been there unchanged from at least XEmacs 19.11. I haven't investigated further who introduced these files so the copyright isn't clear but couldn't that comment warrant that the files be considered GPLv2 or later? sol2.h started out the same way but the comment is now changed to "Completely divergent from FSF.". So what to do with it? (There is of course the long and winding road in trying to find out who did the change but I haven't come to that yet. Hoping for an easy solution here ;-) All of these files are GPLv3 or later in Emacs but they are pretty useless I guess for us at this moment. At a quick glance they look very different which might be expected.

Ah, that’s actually very helpful. Thanks! (On experimentation, odd how it preserves whitespace in some places, but not others; I suppose removing newlines would make the algorithm more difficult.) -- “Apart from the nine-banded armadillo, man is the only natural host of Mycobacterium leprae, although it can be grown in the footpads of mice.” -- Kumar & Clark, Clinical Medicine, summarising improbable leprosy research _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://lists.xemacs.org/mailman/listinfo/xemacs-beta

problems with make-extent in matlab.el using the matlab debugger. 13 years, 11 months

Uwe Brauer

Hello I am not sure whether the problem I describe has to do with the implementation of make-extent in xemacs or the problems lies in a different part of the code. Matlab.el (version 3.1.1) allows to debug matlab code. During the debugging matlab.el, split the window, opens the file you debug, the cursor jumps from line to line and show in the other window via the matlab-shell the result of the executed command. However GNU emacs and Xemacs behave differently In GNU emacs you see in the matlab-shell buffer Someting like 1 tspan=[0 1] Where 1 is underlined and clicking with the mouse on it is jumps to the matlab file which is debugged. In Xemacs however the matlab-buffer displays <a href="matlab: opentoline('/home/oub/ALLES/Matlab-init/testeuler.m',1,1)">1 </a>tspan=[0 1] Which I find very annoying. I tried to debug it but can localise the problem. It seems to me the issue is the code (defun matlab-shell-render-errors-as-anchor (str) "Detect non-url errors, and treat them as if they were url anchors. Argument STR is the text that might have errors in it." (when (string-match matlab-shell-error-stack-end str) (save-excursion (when (re-search-backward matlab-shell-error-stack-start nil t) (let ((groupend nil) (first nil)) (save-excursion (setq groupend (re-search-forward matlab-shell-error-stack-end)) ) ;; We have found an error stack to investigate. (while (re-search-forward gud-matlab-error-regexp nil t) (let* ((err-start (match-beginning 0)) (err-end (match-end 0)) (err-text (match-string 0)) (err-file (match-string 2)) (err-line (match-string 3)) (o (matlab-make-overlay err-start err-end)) (url (concat "opentoline('" err-file "'," err-line ",0)")) ) (matlab-overlay-put o 'mouse-face 'highlight) (matlab-overlay-put o 'face 'underline) ;; The url will recycle opentoline code. (matlab-overlay-put o 'matlab-url url) (matlab-overlay-put o 'keymap matlab-shell-html-map) ;; Keep track of the very first error in this error stack. ;; It will represent the "place to go" for "go-to-last-error". (matlab-overlay-put o 'first-in-error-stack first) (when (not first) (setq first url)) )) ))))) Where the various overlay functions are defaliases to (defalias 'matlab-make-overlay 'make-extent) (defalias 'matlab-overlay-put 'set-extent-property) (defalias 'matlab-overlay-get 'extent-property) (defalias 'matlab-delete-overlay 'delete-extent) (defalias 'matlab-overlay-start 'extent-start-position) (defalias 'matlab-overlay-end 'extent-end-position) (defalias 'matlab-previous-overlay-change 'previous-extent-change) (defalias 'matlab-next-overlay-change 'next-extent-change) Etc. So since GNU emacs and Xemacs behave so differently I thought that maybe make-extent and friend a implemented in a different way. Anybody has an idea? regards Uwe Brauer _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://lists.xemacs.org/mailman/listinfo/xemacs-beta
