Re: [PATCH v2] fsmonitor: implement filesystem change listener for Linux

Thanks for a quick turnaround, but it would be more efficient if you hunted all the leaks yourself, instead of getting a report for one issue and updating the patch to fix that one issue.

Here is what I am getting these:

    $ make SANITIZE=address CC=clang && cd t && sh t7527-*.sh -i -v

Note that "-i" is to say "stop at the first one".

expecting success of 7527.12 'create some files':
        test_when_finished clean_up_repo_and_stop_daemon &&

        start_daemon --tf "$PWD/.git/trace" &&

        create_files &&

        test-tool fsmonitor-client query --token 0 &&

        grep "^event: dir1/new$" .git/trace &&
        grep "^event: dir2/new$" .git/trace &&
        grep "^event: new$"      .git/trace
