    refs: fix locks getting forcibly removed The flag GIT_FILEBUF_FORCE currently does two things: 1. It will cause the filebuf to create non-existing leading directories for the file that is about to be written. 2. It will forcibly remove any pre-existing locks. While most call sites actually do want (1), they do not want to remove pre-existing locks, as that renders the locking mechanisms effectively useless. Introduce a new flag `GIT_FILEBUF_CREATE_LEADING_DIRS` to separate both behaviours cleanly from each other and convert callers to use it instead of `GIT_FILEBUF_FORCE` to have them honor locked files correctly. As this conversion removes all current users of `GIT_FILEBUF_FORCE`, this commit removes the flag altogether.

  • Writing Clar tests for libgit2

    For information on the Clar testing framework and a detailed introduction please visit:

    https://github.com/vmg/clar

    • Write your modules and tests. Use good, meaningful names.

    • Make sure you actually build the tests by setting: 

        cmake -DBUILD_CLAR=ON build/

    • Test: 

        ./build/libgit2_clar

    • Make sure everything is fine.

    • Send your pull request. That’s it.

    Memory leak checks

    These are automatically run as part of CI, but if you want to check locally:

    Linux

    Uses valgrind:

    $ cmake -DBUILD_CLAR=ON -DVALGRIND=ON ..
$ cmake --build .
$ valgrind --leak-check=full --show-reachable=yes --num-callers=50 --suppressions=../libgit2_clar.supp \
  ./libgit2_clar

    macOS

    Uses leaks, which requires XCode installed:

    $ MallocStackLogging=1 MallocScribble=1 MallocLogFile=/dev/null CLAR_AT_EXIT="leaks -quiet \$PPID" \
  ./libgit2_clar
