emacs/admin/FOR-RELEASE

Tasks needed before the next release.

* NEW FEATURES

** Face remapping.

** Make Rmail find the best version of movemail.
To be done by Sergey Poznyakoff <gray@Mirddin.farlep.net>.

** Make VC-over-Tramp work where possible, or at least fail
gracefully if something isn't supported over Tramp.
To be done by Andre Spiegel <spiegel@gnu.org>.

* FATAL ERRORS

** Investigate face cache related crash.

Indications: Face cache seems to have been cleared, but
redisplay uses an invalidated face_id with FACE_FROM_ID
which then returns a NULL pointer.  Said to happen with
isearch faces.

** Investigate reported crashes in compact_small_strings.

** Investigate reported crashes related to using an
invalid pointer from string_free_list.


* LOSSAGE

** Clean up flymake.el to follow Emacs Lisp conventions.

** Fix up url-ldap.el.

* BUGS

** Incomplete overlay mouse-face highlight bug (Ralf Angeli, Oct 18)

** Ange-ftp should ignore irrelevant IPv6 errors:

Message-Id: <4121-Tue23Mar2004165249+0100-piet@cs.uu.nl>
From: "Piet van Oostrum" <piet@cs.uu.nl>
To: emacs-pretest-bug@gnu.org
Subject: Ange-ftp can't deal with IPV6/IPV4 fallback

Symptoms:

C-x C-f /ftp.nluug.nl:/

The problem is that the DNS first gives an IPV6 address. However our
router doesn't do IPV6. Ftp then falls back to IPV4:

ftp> open ftp.nluug.nl
Trying 2001:610:1:80aa:192:87:102:36...
ftp: connect to address 2001:610:1:80aa:192:87:102:36: No route to host
Trying 192.87.102.36...
Connected to ftp.nluug.nl.

Ange-ftp chokes on the `No route to host' message and doesn't look any
further.

I think in the near future we will see more of this problem, so it might be
time to make anfe-ftp more intelligent.

** Bug in url-http-parse-headers, reported in
From: Vivek Dasmohapatra <vivek@zeus.com>
Date: Tue, 28 Sep 2004 16:13:13 +0100

Fetching a url with url-retrieve can reult in an anrbitrary buffer
being killed if a 401 (or possibly a 407) result is encountered:

url-http-parse-headers calls url-http-handle-authentication,
which can call url-retrieve.

This results in the current buffer being killed, and a new http buffer
being generated. However, when the old http buffer is killed, emacs
picks the top buffer from the list as the new current buffer, so by the
time we get to the end of url-http-parse-headers, _that_ buffer is marked
as dead even though it is not necessarily a url buffer, so next time the
url libraries reap their dead buffers, an innocent bystander buffer is
killed instead (and an obsolete http buffer may be left lying around too).

A possible fix (which I am currently using) is to call set-buffer
on the return value of url-http-parse-headers:

      (case url-http-response-status
	(401
	 ;; The request requires user authentication.  The response
	 ;; MUST include a WWW-Authenticate header field containing a
	 ;; challenge applicable to the requested resource.  The
	 ;; client MAY repeat the request with a suitable
	 ;; Authorization header field.
	 (url-mark-buffer-as-dead (current-buffer))
	 (set-buffer (url-http-handle-authentication nil)))
etc ....

which makes sure that it is the right http buffer that is current when
we come to mark the http buffers as dead.



* GTK RELATED BUGS

** Make GTK scrollbars behave like others w.r.t. overscrolling.


* REDISPLAY RELATED BUGS

** Strange text scrolling with Emacs + GTK

> I see the problem around "CC mode" and "Forms".

It is not specific for the first line of a buffer.

Rather it happens for lines which are indented but the
indentation is controlled by a display property and
the newline is part of that display property -- in
that case, the indentation is not recognized for the
first display line.


** Avoid unbreakable loops in redisplay.

Redisplay may loop if there is an error in some display property, e.g.
     (space 'left-margin)

A fix would be to somehow disable handling of display properties if an error
is encountered.


** Problem with modeline and window margins:

The mode line's right "box" line is misplaced under the right margin,
rather than at the right window edge.

** custom mode-line face makes Emacs freeze up

From: Stephen Berman <Stephen.Berman@gmx.net>
Date: Sun, 24 Oct 2004 02:08:56 +0200

1. Start Emacs with -q -no-site-file.

2. Type `M-x customize-face' and at the prompt `mode-line'.

3. In the Custom buffer for mode-line face
   a. check width and give it the value `narrow';
   b. check height and give it the value 120 in 1/10 pt;
   c. check underline and give it the value `on' (or `colored');
   d. check overline and give it the value `on' (or `colored').

4. Set for current session.

5. Invoke Ediff on any two files.

6. Now Emacs is frozen and consumes 95-99% of CPU.

The customizations in step 3 appear to be the minimum necessary to
induce this bug.  Leave out any one of them and Ediff runs without a
problem.  Also if the 1/10 point value of height is 130 or greater
there's no bug (with the default font family; with e.g. Helvetica the
bug is induced only by a value of 100 or less).

I've noticed this freeze up only when invoking Ediff.  The only thing
I've been able to do is kill Emacs externally, via top or with kill
when run in gdb, after interrupting.  When the freeze up happens
within a gdb session, there is no automatic debugging feedback.  After
interrupting I can get a backtrace, here's an example:

Update: Maybe only reveals itself when compiled with GTK+


** Partial highlighting of wrapped overlay

From: Ralf Angeli <angeli@iwi.uni-sb.de>
Date: Mon, 18 Oct 2004 19:09:19 +0200

If you put

(let* ((length (+ (- (window-width) (current-column)) 40))
       (start (point))
       (end (+ (point) length))
       (string (make-string length ?x))
       ov)
  (insert string)
  (setq ov (make-overlay start end))
  (overlay-put ov 'mouse-face 'highlight)
  (overlay-put ov 'display string))

into the *scratch* buffer and type `C-x C-e' with point at the last
parenthesis, you will get a string which does not fit into the line
and has to be wrapped.  If you move over it with your mouse, you
should see that only the part on the second line is being highlighted.
The full string is highlighted only if the 'display property is not
set.
