bug#5562: Emacs 23.1 problem with "tex-bibtex-file" command

[人在江湖]

Below is the bug report created by using "M-x report-emacs-bug", just
that I could not send it successfully.

To: bug-gnu-emacs@gnu.org
Subject: 23.1; problem with "tex-bibtex-file" command
--text follows this line--
In Emacs LaTeX mode, whenever I tried to invoke bibtex command on the
current file by using C-c Tab (equivalent to issusing command
"tex-bibtex-file"), emacs changed the current directory to the home
directory and thus not being able to find the corresponding *.aux
file.

Note that I was actually using Emacs LaTeX mode, not AucTeX mode.

bug#5562: Emacs 23.1 problem with "tex-bibtex-file" command

[Chong Yidong]

Hi Roland, could you take a look at this bug report?  I'm not sure there
is enough info to reproduce, but I'm not familiar with bibtex-mode.
Thanks.

I can try to take a look. But it appears to me that this is not
related with bibtex-mode but latex-mode. bibtex-mode is for managing
a BibTeX database. latex-mode, on the other hand, calls the external
bibtex command (much the same way it also calls the (la)tex command.
I am not familiar with latex-mode.

I can reproduce the bug easily with "emacs -q" for all my LaTeX
files. (Usually I use auctex instead of tex-mode.) But it's not
clear to me, what the code is supposed to do. tex-bibtex-file calls
tex-main-file, which returns a relative filename. If there is just
one LaTeX file, it is this file's name (without any directory). But
then the working directory for the bibtex command is what
file-name-directory returns for the relative file name returned by
tex-main-file. This directory is usually nil. So the working
directory for the bibtex command becomes the $HOME directory and
bibtex fails.

I suggest, someone should look at this who is more familiar with
what tex-mode.el is supposed to do. This is a bug that should be
fixed before the next release.

Thanks; fixed.

A very stupid question: where do I find this fix?

Thanks,
