pcl-cvs: suppress empty dirs?

pcl-cvs: suppress empty dirs?

[Robin Dunn]

Hi,

I've just started using a emacs 22.0.50 snapshot and have been able to 
migrate all of my prior settings and customizations, but there is one 
new 'feature' that is bugging me.  When I do a cvs-examine in pcl-cvs 
then any old empty directories still in the repository are showing up 
with "new-dir  Need-Update" which is real annoying.  I'd rather that 
they just didn't show up at all like in the old version.  I've tried 
setting cvs-auto-remove-directories, and adding a regex to 
cvs-parse-ignored-messages, but still no luck.  Does anybody know how to 
suppress these lines?  They come from the cvs server like this:

cvs server: New directory `this/is/the/pathname' -- ignored

Yes, it's annoying, but it can be very useful if it really means what
it says.  To get rid of the warning, add the entry to the .cvsignore file
(with a final /).

I am in the same testing situation.
I face again the problem discussed in

http://groups.google.fr/group/gnu.emacs.help/index/browse_frm/thread/7e593f35d0d991eb

Is there any better solution than patching - again -
cvs-retrieve-revision

detection of coding-system in cvs-retrieve-revision (was: pcl-cvs: suppress empty dirs?)

Contacting the author would be a good way to maximize the chances that the
problem gets fixed, so that you won't have to re-patch again and again.

Does the patch below do the right thing?

[Jérôme]

Hello
Yes, It seems to do the right thing

Sorry not to contact you directly, but I thought that you were one of
the contributors of the original thread.

And I really start using Emacs 22 only a little while ago.

Thanks again.

Re: detection of coding-system in cvs-retrieve-revision (was: pcl-cvs: suppress empty dirs?)

[RichH]

Should I report pcl-cvs bugs to you?

cvs-commit of things in multiple directories is broken
in the latest win32 version (22.0.50.1).  There seems to
be an extra -f on the second execution of cvs.

Cheers,
Rich

We've got about 10 years or so of revisions in the CVS repository of a 
very active project and have ended up with a lot of directories that are 
now empty (no current revisions, just stuff in the Attic) and so with 
this new 'feature' of pcl-cvs we can end up with 150+ lines of garbage 
in the buffer hiding the few lines that really mean something.  If the 
cvs output says that it is "ignored" shouldn't pcl-cvs ignore it too?

The problem with this is that I also use CVS repositories that I don't 
have write access too, so instead of the new-dir lines I'll end up with 
lines telling me that .cvsignore has been updated.

I've written a small script to wrap cvs such that if "update" is on the 
command line it pipes cvs's output through grep to remove the lines that 
are confusing pcl-cvs.  It works fine on Linux and OS X, but so far I 
can't seem to get the pcl-cvs on Windows to execute anything but an .exe 
file...


#!/bin/bash

CVS=/usr/bin/cvs
TRIM=no

for a in "$@"; do
     if [ "$a" == "update" ]; then
	TRIM=yes
     fi
done

if [ "$TRIM" == "yes" ]; then
     $CVS "$@" 2>&1 | grep -ve "New directory.*ignored"
else
     $CVS "$@"
fi

If you convert the script to a Windows batch file, you will have no
problem running it on Windows, exactly like you run shell scripts on
Unix and GNU/Linux.

I agree.  If this is the default behaviour of the next Emacs, I will
have to see if I can get an older pcl-cvs to run, overriding the one
distributed with emacs.

Which would be both a hazzle and a pity, from my POV.

Re: pcl-cvs: suppress empty dirs?

[Jérôme]

It is quite straightforward to patch pcvs-parse.el to have the Emacs 21
behavior.
See patch below.
Maybe it would be good to add an option to let people choose the
behavior they want.
I will try to suggest this to the maintainer of this package
