Subject: bug#5133: 23.1; ispell-buffer with LaTeX file VERY slow in nextstep port of emacs 23.1.1
Date: Sat, 5 Dec 2009 23:31:51 -0500 [thread overview]
Message-ID: <20091206043151.GB7663@srevilak.net> (raw)

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
I often use emacs for writing LaTeX, with the help of "aspell" as a
spell-checking program. With the nextstep port of Emacs 23.1.1,
spell-checking a latex document is approximately 50 times slower than
spell-checking the same latex document with Emacs 22.3.1.
My test case uses the LaTeX version of GPL 3.0. I've posted a copy of
the latex file here:
http://www.cs.umb.edu/~srevilak/images/gpl-3.0.tex
I will also attempt to attach a copy of gpl-3.0.tex to this bug
report.
If you examine this copy of gpl-3.0.tex, you'll notice a "LocalWords"
section at the bottom. As a preparation step, I've run this file
through ispell-buffer, and used `A' to add all misspelled words. The
goal is to see how long it takes ispell-buffer to spell check the
file, and declare that there are no spelling errors.
Specific steps to reproduce:
1) start emacs, with --no-init-file
shell> /Applications/Emacs-23.1.app/Contents/MacOS/Emacs --no-init-file
2) switch to scratch buffer
C-x b *scratch* RETURN
3) specify aspell as the ispell program
;; eval with C-x C-e
(setq ispell-program "aspell")
4) Open gpl-3.0.tex
C-x f /path/to/gpl-3.0.tex RETURN
5) spell-check the buffer
M-x ispell-buffer RETURN
Again, I've arranged things such that there are no spelling errors for
aspell to find.
The nextstep port of emacs 23.1.1 takes 57 seconds to spell-check
gpl-3.0.tex.
By contrast, an older version of emacs:
GNU Emacs 22.3.1 (powerpc-apple-darwin8.11.0, Carbon Version 1.6.0)
of 2009-03-28 on spud.local
takes less that 1 second to perform the same task, on the same
computer, using the same aspell binary.
As another point of contrast
GNU Emacs 23.1.1 (i586-suse-linux-gnu, GTK+ Version 2.18.1) of
2009-10-24 on build16
running on a GNU/Linux system also takes less than 1 second to
accomplish this task. Thus, the `slow ispell-buffer' behavior appears
to be specific to the nextstep port of emacs 23.1.1, compiled on Mac
OS X.
The version of aspell that I am using:
@(#) International Ispell Version 3.1.20 (but really Aspell 0.60.6)
uname -a output for this system:
Darwin spud.local 8.11.0 Darwin Kernel Version 8.11.0: Wed Oct 10 18:26:00 PDT 2007; root:xnu-792.24.17~1/RELEASE_PPC Power Macintosh powerpc
If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
`bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/Applications/Emacs-23.1.app/Contents/Resources/etc/DEBUG for instructions.
