    tests: diff: verify that we are able to diff with empty subtrees

While it is not allowed for a tree to have an empty tree as child (e.g.
an empty directory), libgit2's tree builder makes it easy to create such
trees. As a result, some applications may inadvertently end up with such
an invalid tree, and we should try our best and handle them.

One such case is when diffing two trees, where one of both trees has
such an empty subtree. It was reported that this will cause our diff
code to fail. While I wasn't able to reproduce this error, let's still
add a test that verifies we continue to handle them correctly.

  • README.md

  • 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
