    refs: Speed up packed lookups. Currently ref lookups require loading the entire packed-refs file into a hashmap in memory. For repos with large numbers of refs this can be painfully slow. This patch replaces the existing lookup code and instead mmap()'s the packed-refs file and performs a binary search to locate the ref entry. Git uses a similiar approach. The old hash table codepath is still used for unsorted packed-refs files. This patch also fixes a minor bug where the "peeled" trait is never parsed correctly from the packed-refs header.

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

    • Make sure you actually build the tests by setting: 

        cmake -DBUILD_TESTS=ON build/

    • Test: 

        ./build/libgit2_tests

    • 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_TESTS=ON -DVALGRIND=ON ..
$ cmake --build .
$ valgrind --leak-check=full --show-reachable=yes --num-callers=50 --suppressions=../libgit2_tests.supp \
  ./libgit2_tests

    macOS

    Uses leaks, which requires XCode installed:

    $ MallocStackLogging=1 MallocScribble=1 MallocLogFile=/dev/null CLAR_AT_EXIT="leaks -quiet \$PPID" \
  ./libgit2_tests
