bug with ampersand modules, cvs client, and tags

[Greg Klanderman]

Hi,

I've come across a rather obscure bug involving ampersand modules, cvs
client, and tags.  I've tested against cvs versions up through 1.11.
I tried to report this bug last fall, but I believe the email bounced.

Essentially, if you have two projects, "foo", and "bar", and create a
"baz" module as follows, in the modules file:

        baz -d foo foo &i_bar

        i_bar   -d two/bar   bar

then "baz" is created by checking out "foo", and then checking out
"bar" within "foo"s "two" directory.

Now, if you check out "baz", using a tag, using client-server CVS,
the "Tag" file will be missing in the directory "foo/two/CVS".  The
problem does not exist unless using client-server mode.

I've attached below a tar'd and gzipped repository, repos.tgz,
exhibiting this bug.  To see it, with the tarball untarred in
/phl/greg/junk/repos, do the following to see the bug does not exist
in non client-server mode:

        [test4] phl| cvs -d /phl/greg/junk/repos co -r branch baz         
        cvs checkout: Updating foo
        U foo/one
        cvs checkout: Updating foo/two
        U foo/two/four
        cvs checkout: Updating two/bar
        U two/bar/three
        [test4] phl| ls -l foo/two/CVS/
        total 16
        -rw-r--r--   1 greg     ita            54 Oct 19 20:51 Entries
        -rw-r--r--   1 greg     ita             8 Oct 19 20:51 Repository
        -rw-r--r--   1 greg     ita            21 Oct 19 20:51 Root
        -rw-r--r--   1 greg     ita             8 Oct 19 20:51 Tag

But in client-server mode:

        [test5] phl| cvs -d greg@phl:/phl/greg/junk/repos co -r branch baz
        cvs server: Updating foo
        U foo/one
        cvs server: Updating foo/two
        U foo/two/four
        cvs server: Updating two/bar
        U two/bar/three
        [test5] phl| ls -l foo/two/CVS/
        total 12
        -rw-r--r--   1 greg     ita            54 Oct 19 20:52 Entries
        -rw-r--r--   1 greg     ita             0 Oct 19 20:52 Entries.Static
        -rw-r--r--   1 greg     ita             8 Oct 19 20:52 Repository
        -rw-r--r--   1 greg     ita            30 Oct 19 20:52 Root

Notice that the Tag file does not exist, and there's an additional
"Entries.Static" file with zero length.

Thanks for any help you may be able to provide,
