Periodically I am reminded that the git-cvsserver does not pass it's tests (t9400-git-cvsserver.sh) on my machine, so I once again ask for help. The failing tests are: (they say skip because this is from the last "find other errors" run)

* skip 9: req_Root failure (strict-paths)
* skip 11: req_Root failure (w/o strict-paths)
* skip 13: req_Root failure (base-path)

No other tests fail, including other req_Root failure tests :

*   ok 6: req_Root failure (relative pathname)
*   ok 7: req_Root failure (conflicting roots)
*   ok 15: req_Root failure (export-all w/o whitelist)

All three tests fail with the exact same error log:

E /Users/brian/dev/git/t/trash/gitcvs.git/ does not seem to be a valid GIT repository E error 1 /Users/brian/dev/git/t/trash/gitcvs.git/ is not a valid repository E Invalid root /Users/brian/dev/git/t/trash/gitcvs.git

This appears to be from git-cvsserver.perl:148-9:

     req_Root('root', $line) # reuse Root
        or die "E Invalid root $line \n";

This fails the test suite because die() exits with code 255 (checked with "perl -e 'die'; echo $?"), which is outside what test_expect_failure accepts (see t/test-lib.sh:179).

My questions become:
1) Why hasn't this hit anyone else?
2) Is this where these tests are supposed to fail?
3) If it is, should the code be using print and exit 1 instead of die?
4) If not, should the test be altered to end with "|| false" or  
similar so the test passes?

I'd happily submit a patch to fix this, but don't know what the correct fix is.

Hi.

Some investigations on this:

die doesn't always quit with 255:

"exits with the current value of $! (errno). If $! is 0, exits with the value of "($? >> 8)" (backtick ‘command‘ status). If "($? >> 8)" is 0, exits with 255"

On my system $! is 9 for these cases and so it exits with exit code 9.

yes, IIRC

I think that would be the best solution, yes.

[PATCH] Use exit 1 instead of die when req_Root fails.

This was causing test failures because die was exiting 255. ---

 This finally takes care of my test failures.
