[AC21.5] Ensure that gdbinit.in gets processed into .gdbinit
13 years, 3 months

APPROVE COMMIT 21.5
I don't see how the current setup for creating a .gdbinit ever worked
for anyone. It simply sources .gdbinit.in from srcdir to .gdbinit.in
in blddir, then processes that trivial file. I guess this would work
with build in srcdir, but not with configure --srcdir. There was
another problem, which is that the debugger init files now depend on
config.h. Thus, we really need to redo them any time config.h
changes. Since it takes essentially zero time, I've arranged to
always do it.
This patch
(1) moves the debugger templates from src/.gdbinit.in and
src/.dbxrc.in to etc/gdbinit.in and etc/dbxrc.in. I figure
hackers are more likely to notice them there.
(2) makes the configure code that hacks these guys dependent only on
existence of the template, not on nonexistence of the target.
(3) arranges for *brief* comments on licensing and where to find usage
hints in .gdbinit. I'd do it for .dbxrc too but I don't know the
comment syntax there. This is done using the imake XCOMM
convention, and it could be used in Makefile.in.in, too.
To apply this patch, you need to mv the templates as indicated in (1),
then apply it with patch -p1.

[PATCH] Fix broken -unmapped.
13 years, 3 months
Malcolm Purvis
Malcolm Purvis
Back in April Giacomo Boffi reported that -unmapped was broken in 21.5. This
fixes it so once again no frame appears.
The problem was that the updated version of display-splash-screen called
pop-to-buffer, which mapped the frame. pop-to-buffer is moved to the
interactive function xemacs-splash-buffer instead.
Malcolm

2006-05-25 Malcolm Purvis <malcolmp(a)xemacs.org>
* startup.el (display-splash-screen): No longer bring buffer the
front. Fixes problems with -unmapped.
* startup.el (xemacs-splash-buffer): Pop splash buffer to the
front here instead.

[PATCH (pkgs)] New comint
13 years, 3 months
Jerry James
Jerry James
PATCH packages
This is a freshly minted sync with the Emacs comint.el. It also fixes a
number of subtle bugs. Note the uses of buffer-local variables
comint-after-partial-filename-command,
comint-dynamic-complete-command-command, and friends in shell.el.
According to the ChangeLogs, those variables were removed from the Emacs
comint.el in (drum roll, please) 1994. I don't know when they
disappeared from the XEmacs comint.el, but they sure aren't there now.
There were several instances where the Emacs comint.el and the XEmacs
comint.el solved the same problem in different ways. I resolved those
instances on a case-by-case basis. In some cases, I thought the XEmacs
solution superior and kept it. In other cases, I didn't see any real
advantage to either side; then I went with the Emacs solution for ease
of future syncing and for potentially better Emacs compatibility.
I may not be able to commit this for awhile, or fix problems that people
discover in it. If someone would like to take over the project, do so
with my blessing. Otherwise, I'll push this forward when I am able to
do so.
xemacs-packages/python-modes/ChangeLog addition:
2006-05-16 Jerry James <james(a)xemacs.org>
* pydoc.el (pydoc-kill-async-output): Change the obsolete
comint-kill-output to comint-delete-output.
xemacs-packages/xemacs-base/ChangeLog addition:
2006-05-16 Jerry James <james(a)xemacs.org>
* field.el (field-at-pos): New function, synced from Emacs.
* comint.el: Numerous changes to sync with Emacs.
* shell.el: Ditto.

+
+;; This little add-on for comint is intended to make it easy to get
+;; output from currently active comint buffers into another buffer,
+;; or buffers, and then go back to using the comint shell.
+;;
+;; My particular use is SQL interpreters; I want to be able to execute a
+;; query using the process associated with a comint-buffer, and save that
+;; somewhere else. Because the process might have state (for example, it
+;; could be in an uncommitted transaction), just running starting a new
+;; process and having it execute the query and then finish, would not
+;; work. I'm sure there are other uses as well, although in many cases
+;; starting a new process is the simpler, and thus preferable, approach.
+;;
+;; The basic implementation is as follows: comint-redirect changes the
+;; preoutput filter functions (`comint-preoutput-filter-functions') to use
+;; its own filter. The filter puts the output into the designated buffer,
+;; or buffers, until it sees a regexp that tells it to stop (by default,
+;; this is the prompt for the interpreter, `comint-prompt-regexp'). When it
+;; sees the stop regexp, it restores the old filter functions, and runs
+;; `comint-redirect-hook'.
+;;
+;; Each comint buffer may only use one redirection at a time, but any number
+;; of different comint buffers may be simultaneously redirected.
+;;
+;; NOTE: It is EXTREMELY important that `comint-prompt-regexp' be set to the
+;; correct prompt for your interpreter, or that you supply a regexp that says
+;; when the redirection is finished. Otherwise, redirection will continue
+;; indefinitely. The code now does a sanity check to ensure that it can find
+;; a prompt in the comint buffer; however, it is still important to ensure that
+;; this prompt is set correctly.
+;;
+;; XXX: This doesn't work so well unless `comint-prompt-regexp' is set;
+;; perhaps it should prompt for a terminating string (with an
+;; appropriate magic default by examining what we think is the prompt)?
+;;
+;; Fixme: look for appropriate fields, rather than regexp, if
+;; `comint-use-prompt-regexp' is true.

[COMMIT] Last build problem was with eicpy_ext, not stderr_out

* file-coding.c (output_bytes_in_ascii_and_hex):
I installed GCC 4.0 (which may not even have been necesssary,
-pedantic might have done it) and it showed me that the problem my
last commit intended to address was in eistr_ext rather than
stderr_out.

[21.5] Fix the no-mule detection test failure/abort
13 years, 4 months
Stephen J. Turnbull
Stephen J. Turnbull
21.5
Ben, please review. I think your "Great Mule Merge" patch simply
didn't consider that all XEmacsen >=21.5.6 do EOL processing on
request, and removed the hardcoded conditional without replacing it
with the needed runtime conditional. Please confirm.
Not for 21.4.
This patch fixes the C-level tests of file-coding (ie, EOL handling)
to properly account for the runtime configuration of EOL conversion.
In light testing it seems to fix the abort in test without introducing
problems in other configurations, but it needs more testing.
Thanks to Ben and Malcolm for past discussions and thread URLs.
Note that the patch needs -p1 to apply, not -p0.

[21.5] Clarify code in code-cmds.el
13 years, 4 months
Stephen J. Turnbull
Stephen J. Turnbull
21.5
Ben, please comment on whether this patch will interfere with synchs we
should do. I had great trouble understanding the code, and I think
this is much clearer (in addition to doing some sanity checks), but
I'll defer to your opinion.
Use "patch -p1" to apply.
