This bug report will be sent to the XEmacs Development Team,
not to your local site managers!!
Please write in English, because the XEmacs maintainers do not have
translators to read other languages for them.
Please describe as succinctly as possible:
- What happened.
- What you thought should have happened.
- Precisely what you were doing at the time.
Please also include any C or lisp back-traces that you may have.

Dear Bug Team!
On Windows there is an infinite loop in the function p4-detect-p4 in p4.el.
The code in question is:
(let ((p4config (getenv "P4CONFIG"))
(p4-cfg-dir (cond (buffer-file-name ;; extrapolate from name
(file-name-directory
(file-truename (buffer-file-name))))
(t default-directory) ;; hmm, use default
)))
(while (not (or (string-match "^\\([a-zA-Z]:\\)?/$" p4-cfg-dir)
(file-exists-p (concat p4-cfg-dir p4config))))
(setq p4-cfg-dir
(substring p4-cfg-dir 0
(string-match "[^/]*/?$" p4-cfg-dir))))
Which is supposed to traverse up a directory tree looking for a
p4config file and thus show that this is a file controlled by Perforce.
However, in the case of windows, the setq at the end of the loop will
reset p4-cfg-dir to "", which will never match the loop termination
condition. Thus the infinite loop in the case when there is no
p4config file in the file tree (which is a common occurance).
On an aesthetic note, doing filename manipulations like this is ugly
and error prone.
The solution to the problem is to replace the loop with:
(while (not (or (string= p4-cfg-dir
(file-name-directory (directory-file-name p4-cfg-dir)))
(file-exists-p (concat p4-cfg-dir p4config))))
(setq p4-cfg-dir
(file-name-directory (directory-file-name p4-cfg-dir))
))
This uses the XEmacs built-in filename manipulation routines to find
the parent directories, and should work on all filesystems (tested on
Windows only). For termination, it relies on the fact that the parent
directory of the root is the root in Unix or DOS filesystems ie
(file-name-directory (directory-file-name "/")) is "/".

Hi Malcolm!
Thanks for reporting this problem.
If you would like to get involved a bit more, could you please provide
a patch, which also uses expand-file-name instead of concat?
Thanks in advance,
Adrian

Shouldn't that be (expand-file-name p4config p4-cfg-dir) ?

Malcolm, could you also provide a ChangeLog entry and send it along with
the patch to <xemacs-patches(a)xemacs.org>?
BTW; I checked the beta version of p4.el at
<http://www.dsmit.com/p4/p4.el-9.0>;, and it looks like it's been fixed
there too, in a slightly different manner due to some new features.
TIA,

Thanks for the patch, Malcolm!
Unfortunately, your mail got line-wrapped which broke your patch.
Even after I repair that your patch does not apply.
Is this patch probably not against latest CVS?

Ville, can you please look into syncing with upstream?
I'm too busy to get the build package ready for pre-release and sumo.

For the last few year Peter Osterlund has been a de-facto maintainer
of p4.el. See http://w1.894.telia.com/~u89404340/index.html#p4.el
I added Peter to CC.
We should probably sync to that version and make sure our patches get
propagated to Peter. Or, perhaps, Peter would volunteer to maintain
p4.el in XEmacs CVS as is XEmacs tradition (assuming this is good for
everybody)?

Thanks a lot for the info, Gleb, and hi Peter!

Yes, I'll look into syncing with Peter's version, unless (see below):

That would be fantastic. What do you think, Peter?

Sure, unless Rajesh wants the job, I'll be happy to do it.
