Would you accept a patch that removes those tags ($Id, $Date, etc.) from

I see no objection but I prefer to be seconded before applying it (so
maybe wait an other '+1' before doing it ;))
No, don't do that please. We use them to keep track of stuff.
Thanks for the quick reply.
Could you elaborate on that? I've never used those tags myself, so I'm
wondering what further information they could provide that CVS doesn't.
It just means it's recorded in the file so if we move the file from
that CVS to another one it keeps at least that information.
Not in my experience. Consider the $Id string in
http://savannah.gnu.org/cgi-bin/viewcvs/classpathx/jaxp/source/gnu/xml/util/XMLWriter.java?rev=1.8&content-type=text/vnd.viewcvs-markup
vs. the one in
http://www.kaffe.org/cgi-bin/viewcvs.cgi/kaffe/libraries/javalib/gnu/xml/util/XMLWriter.java?rev=1.1&content-type=text/vnd.viewcvs-markup
it's completely different. the author, the date. just the file name is
the same. That's because the contents of those tags are automatically
insterted by RCS/CVS upon checkin, AFAIK. So when you move the file from
one CVS to another, as in 'check it in', the old $Id tag gets
overwritten by a new one, causing a frivolous difference in files.
But I may be ignorant of other possibilities to move files between CVS
archives, so it would be nice if you could elaborate some more on that one.
I'm suprised you haven't used the tags. They're quite common.
They seem to be purged from projects as soon as the projects become
important enough that people want to use those projects as 'upstream'
providers of sources. See discussions why those tags were purged from
GCC's Ada sources:
http://gcc.gnu.org/ml/gcc/2002-03/msg00557.html
here's a few more quotes from gcc developers:
http://gcc.gnu.org/ml/gcc-patches/1999-08n/msg00760.html
http://gcc.gnu.org/ml/gcc/2002-03/msg00560.html
See also this thread on lack of use of RCS tags in GNU emacs:
http://mail.gnu.org/archive/html/bug-gnu-emacs/2001-05/msg00042.html
with GNU emacs developers' comments on evilness of tags:
http://mail.gnu.org/archive/html/bug-gnu-emacs/2001-05/msg00088.html
http://mail.gnu.org/archive/html/bug-gnu-emacs/2001-05/msg00095.html
http://mail.gnu.org/archive/html/bug-gnu-emacs/2001-05/msg00062.html
Just to show that I'm not making the problems up ;)
So I'm still interested in what RCS tags provide for you that cvs log
doesn't, or the cvsweb interface.
cheers,
