[Bug: 21.5-b31] seg fault

Dear Bug Team!
I was having trouble with the keyboard or mouse somehow inserting
random junk in my input stream so was about to look at what was
actually being sent. I had put (recent-keys ) into *scratch* and
then did m-x eval-print <enter> when I got the crash.
I had done this earlier without incident.
My init also contained
(set-recent-keys-ring-size 10000)
I have no core file but am prepared to help further.
Here's what I found in the console from which I started xemacs:
(It's just lucky that I started xemacs from a console!)
====
Fatal error (11).
Your files have been auto-saved.
Use `M-x recover-session' to recover them.
Your version of XEmacs was distributed with a PROBLEMS file that may describe
your crash, and with luck a workaround. Please check it first, but do report
the crash anyway.
Please report this bug by invoking M-x report-emacs-bug, or by selecting
`Send Bug Report' from the Help menu. If that won't work, send ordinary
email to `xemacs-beta(a)xemacs.org'. *MAKE SURE* to include this entire
output from this crash, especially including the Lisp backtrace, as well as
the XEmacs configuration from M-x describe-installation (or equivalently,
the file `Installation' in the top of the build tree).
*Please* try *hard* to obtain a C stack backtrace; without it, we are unlikely
to be able to analyze the problem. Locate the core file produced as a result
of this crash (often called `core' or `core.<process-id>', and located in
the directory in which you started XEmacs or your home directory), and type
gdb /usr/bin/xemacs core
then type `where' at the debugger prompt. No GDB on your system? You may
have DBX, or XDB, or SDB. (Ask your system administrator if you need help.)
If no core file was produced, enable them (often with `ulimit -c unlimited')
in case of future reoccurrence of the crash.
Lisp backtrace follows:

WARNING: ---------------------------------------------------------
WARNING: This tends to trigger compiler bugs, especially when
WARNING: combined with MULE and ERROR_CHECKING. Crashes have
WARNING: been seen with various versions of GCC (up to about 2.95),
WARNING: and recently with Visual C++ as well (mid-2003).
WARNING: More recent versions may be safer, or not.
WARNING: ---------------------------------------------------------

WARNING: ---------------------------------------------------------
WARNING: The new algorithms are experimental. They are enabled by
WARNING: default for this release. Use `--disable-kkcc' to
WARNING: turn it off.
WARNING: ---------------------------------------------------------
Using the new portable dumper.
Dumping into executable.

coding problem with babel.el (babelfish interface)
13 years
Uwe Brauer
Uwe Brauer
Hello
I have a problem with the babel package. This package allows to use
online translators, such as Google[1], Babelfish and
others. The problem I encounter happens with the babelish
(yahoo) service. It is a coding problem, since there is *no*
problem if the text of language A and B contains only ASCII.
Now I have to say that there is no problem whatsoever using
GNU emacs. However using Xemacs-21.5.31 (Mule)[2] I
encounter two problems. That is why I write to the list and
CC the author of the package.
- The word of language A contains only ascii symbols,
but the translated word does not. In that case the
word seems to contain a UTF-8 however the symbol is
surrounded by a green box and when I put the cursor
on it to use
what-cursor-position I obtain
Char: � (U+2000C9 jit-ucs-charset-0 34 121) point=1065 of 1310(81%) column 1
while when I use it on É (which I typed in a xemacs buffer) I obtain
Char: É (U+00C9 latin-iso8859-1 73) point=1071 of 1320(81%) column 1
I have just insert such a word in the message, I am not
sure it will be send correctly.
�gal
- the next problem is more severe. If a word of
language A contains a no ascii symbol (and I use
,----
| `buffer-file-coding-system' is a built-in buffer-local variable.
| -- loaded from "/home/oub/xemacs/init/xemacs_init.el"
|
| Value: utf-8-unix
`----
there are two possibilities:
- the word Égal with
Char: É (U+00C9 latin-iso8859-1 73) point=1071 of 1320(81%)
column 1
Gets translated (French to German) to � � gal
- While
�gal
With
Char: � (U+2000C9 jit-ucs-charset-0 34 121) point=1065 of 1310(81%) column 1
gets translated to
Entsprech
<P>
So I am puzzled. Any comments? Should I use a different
coding system?
Uwe Brauer
Footnotes:
[1] the google interface, gave some problem with the
correct coding in the past, but it is currently
desactivated since google again changed its protocol.
[2] the UTF-8 support of 21.4 via UCS is not sufficient.

This is what happens when Latin-1 is decoded as UTF-8, since I changed the
UTF-8 coding systems to avoid transforming every octet that is not valid
UTF-8 to tilde. Basically, babel (or more probably, the URL-retrieval code)
isn’t looking at the MIME information about what coding system the data is
in at all.

still codings problem (saving) with babel.
13 years
Uwe Brauer
Uwe Brauer
Hello
there is still a problem concerning,inserting and saving
translated text. Take the word `to answer', which is translated
to french as répondre.
Now Babelfish gives me a buffer and the word is displayed
Char: � (U+2000E9 jit-ucs-charset-0 35 56) point=467 of 473(99%) column 2
r�pondre
Now I have three possibilities.
- I insert this word into my buffer which contains
other french words and save it as iso-8859-1; result
the new word is saved as r~pondre.
- I save in UTF8. then all the symbols are saved as some
sort of japanese Syllables alphabet (I don't speak
japanese, this is a guess)
- I convert all the french words, via iso-unaccentuate
to ascii and save the file as UTF, then répondre is
saved correctly! I can then iso-accentuate the rest
of the words and continue with UTF8 coding.iplayed
so I am puzzled about which coding to chose.
Regards
Uwe Brauer

[PATCH21.4] fix bug in parsing ^ after shy group in regex

regexp bug
13 years
Julian Bradfield
Julian Bradfield
Either I have a profound mis-understanding, or XEmacs (latest stable
and beta) has a bug in the regular expression handling:
(string-match "^\\|c" "")
0 ; ok
(string-match "\\(^\\|c\\)" "")
0 ; ok
(string-match "\\(?:^\\|c\\)" "")
nil ; wtf?
(string-match "\\(?:^\\|c\\)" "c")
0 ; ok
(string-match "\\(?:c\\|^\\)" "")
0 ; ok
;; and even
(string-match "\\(?:^\\)" "")
nil ; wtf?
; but
(string-match "\\(?:^\\)" "^")
0
In short, ^ seems to be mis-understood as a literal character when
immediately following a shy grouping open.
A few minutes later...
The offending code is at_begline_loc_p() in regex.c, which hasn't been
told about shy grouping.
If you like, I can propose a fix, but if somebody else knows the regex
code well (in particular all the bits that control syntax variations),
that would be better;-)

C Mode possibility: optionally disabling K&R function headers. WDYT?
13 years
Alan Mackenzie
Alan Mackenzie
Hello Emacs and XEmacs.
I've got a knotty problem with a C Mode bug report: The use of a macro
in a typedef definition causes the following line to be parsed as a K&R
parameter. The actual code is this:
#ifndef G
#define G(symbol) pieni_ ## symbol
#endif
typedef struct G(foobar) *G(foobar_t);
typedef int lahna; <=========== K&R
Solving this bug is difficult. One way would be just to disable K&R in
C Mode, except when explicitly enabled by the user. After all, K&R
parameters have been obsolete for over 10 years now.
The key sequnce to toggle it would be C-c C-k.
Can anybody think up any reasons why this would be a Bad Thing. Does
anybody feel particularly strongly about this?

The closest appropriate WHEN is :load-toplevel, and that’s limited to top
level forms, while load-time-value can be deep in a function or macro body
without problems.

RE: package system improvements!?
13 years
steven Mitchell

Mats,
I was reading the README in /usr/local/share/xemacs-21.5.b31/etc,
and they talk about an option called "install-bootstrap-packages"
and I was wondering if that is a possible mechanism for getting the two
packages installed for bootstrapping the rest of the package system?
Not sure, just thought I would point it out.
The README continues:
"you may choose what packages you wish to include in
bootstrap.tar.gz, but to make list-packages work you need to include at
least xemacs-base, dired, and efs. The tarball should unpack directly as
an xemacs-packages tree (and optionaly, a mule-packages tree."
I was wondering if we included just the 2 (or 3) files they mention, but
no others, would that be a way to get the package system up enough to be
able to get it going?
As a side note, I was able to install without dired, so I am not sure if
that is needed to actually install the package system--didn't seem to
need it.
