How to list all modules in a CVS repository

cvs

Is there a command that returns a list of module names contained within a CVS repository?

Being a newbie to CVS, I imagine that there should be something along the lines of

cvs -d /usr/local/cvs listmodules

What should I substitute listmodules with to get a list of all modules within the CVS repository?

To address Dewfy's comment, cvs --help-commands returns the following:

    add          Add a new file/directory to the repository
    admin        Administration front end for rcs
    annotate     Show last revision where each line was modified
    checkout     Checkout sources for editing
    commit       Check files into the repository
    diff         Show differences between revisions
    edit         Get ready to edit a watched file
    editors      See who is editing a watched file
    export       Export sources from CVS, similar to checkout
    history      Show repository access history
    import       Import sources into CVS, using vendor branches
    init         Create a CVS repository if it doesn't exist
    kserver      Kerberos server mode
    log          Print out history information for files
    login        Prompt for password for authenticating server
    logout       Removes entry in .cvspass for remote repository
    pserver      Password server mode
    rannotate    Show last revision where each line of module was modified
    rdiff        Create 'patch' format diffs between releases
    release      Indicate that a Module is no longer in use
    remove       Remove an entry from the repository
    rlog         Print out history information for a module
    rtag         Add a symbolic tag to a module
    server       Server mode
    status       Display status information on checked out files
    tag          Add a symbolic tag to checked out version of files
    unedit       Undo an edit command
    update       Bring work tree in sync with repository
    version      Show current CVS version(s)
    watch        Set watches
    watchers     See who is watching a file

The CVS version is 1.11.22.

As already described in this answer there are basically three ways to go about this. Which one suits your situation depends firstly on what versions of CVS you are using on both client and server and secondly on your definition of "modules".

If you are referring to modules as they were originally thought of by the CVS authors, i.e. as entries in the CVSROOT/modules file then cvs co -c or cvs co -s will give you that, the only difference between the two being that the latter will sort the output by "status". You can read about the modules file here: http://cvsbook.red-bean.com/cvsbook.html#modules
If you are using at least CVS 1.12.8 or CVSNT and your idea of modules corresponds more to actual directories inside the repository, then cvs ls should be what you want.
Finally, if you are indeed after a remote directory listing but your server is running an older version of CVS, then there's the trick of first performing a "fake" checkout and then simulating a recursive update:

cvs -d [CVSROOT] co -l .

cvs -n up -d

Actually your initial approach was very close to the solution. The problem is, that joining date-based does not handle removed files and directories correctly. You need to set a tag to the code base you want to join first:

mkdir code_base1 && cd code_base1
cvs co -D "2008-12-30" modulename
cvs tag code_base_2008_12_30

Now do the join tag-based, subtracting all changes between now and 2008-12-30:

cd .. && mkdir code_base2 && cd code_base2
cvs co modulename
cvs update -d -j HEAD -j code_base_2008_12_30  # use -d to resurrect deleted directories

Compare the contents of code_base1 and code_base2. They should be identical except for the CVS meta information. Finally commit the code as it was on 2008-12-30 as new HEAD:

cvs commit -m "Revert all changes this year"

Note that tagging the code you wish to join like this will not work, because rtag also does not handle removed files and directories correctly, when using -D:

cvs rtag -D "2008-12-30" code_base_2008_12_30 modulename

How to check out a CVS branch point

Since you did not set a tag when branching, the only way I see, is to use the date approach. But you can still set that tag now. Lets assume you want to call that initial release "ReleaseX0", because unfortunately the name "ReleaseX" is already occupied for the branch. Depending on whether you want to set the tag on the branch or on the MAIN branch you can use either of these checkout commands:

cvs co -r releaseX -D "2008-12-30" modulename
cvs co -D "2008-12-30" modulename

Then set the tag:

cvs tag releaseX0

From now on you can checkout this release in the same way as you checkout the other releases.

As you pointed out in your comment to my initial response, renaming the branch from releaseX to releaseX_branch like this does not work:

cvs rtag -r releaseX releaseX_branch modulename
cvs rtag -d releaseX modulename

To rename a branch cvs admin -N < old >:< new > needs to be used. But renaming a branch is a bad idea anyway. (I am sorry for bringing it up in the first place ;-).), Renaming will mess up the working copies of other users. So it is probably best to stick with the original name.
