RE: How to find out the CVSROOT and location in the repository of a w orking directory |

About the first possibility below, this was the first thing that I tried
before I sent the message to the mailing list.
I noticed that I have a problem with sticky dates: I cannot take the sticky
date from the output of "cvs status" and just use "cvs update -D
<sticky-date>". I need to do a format conversion, and moreover, I need to
translate the timezone!
I preferred not to use the 2nd option because then I would need to add
support for each OS/shell. (The copy command would be different.)
Just FYI, I am no longer interested in a solution for this because I am now
taking a different approach to my problem, which avoids the need in any CVS
operations. However, I have learned a few very valuable and interesting
things during this discussion...
Thanks,
Shlomo

Three possibilities:
1. Do this in place, without using a temporary directory:
- use "cvs status lock-file" (no -t needed) to learn which
is the sticky branch or date for the file, if any
- use "cvs update -r <new-branch> lock-file" to put the
lock file onto the correct branch
- make your changes, and commit
- use "cvs update -C" (and either -D/-r or -A) to restore
the lock file to its previous state
2. Use the temporary directory, but copy it from the working
directory rather than checking it out fresh.
- Use something like this shell pseudocode to set up the
temporary directory:
cd working-dir
mkdir /tmp/foo$$
cp -pR lock-file CVS /tmp/foo$$
(Note that we only copy the lock file itself, not the
rest of the directory's contents.)
- Make your changes to the temporary copy
- Commit. You'll have to name the file explicitly:
cvs commit lock-file
Otherwise the up-to-date check will fail, because all
the other files in the (temporary) working directory
will be missing.
3. As Larry Jones says, give in and use CVS/Root and
CVS/Repository.
