    filter: only close filter if it's been initialized correctly In the function `git_filter_list_stream_data`, we initialize, write and subesquently close the stream which should receive content processed by the filter. While we skip writing to the stream if its initialization failed, we still try to close it unconditionally -- even if the initialization failed, where the stream might not be set at all, leading us to segfault. Semantics in this code is not really clear. The function handling the same logic for files instead of data seems to do the right thing here in only closing the stream when initialization succeeded. When stepping back a bit, this is only reasonable: if a stream cannot be initialized, the caller would not expect it to be closed again. So actually, both callers of `stream_list_init` fail to do so. The data streaming function will always close the stream and the file streaming function will not close the stream if writing to it has failed. The fix is thus two-fold: - callers of `stream_list_init` now close the stream iff it has been initialized - `stream_list_init` now closes the lastly initialized stream if the current stream in the chain failed to initialize Add a test which segfaulted previous to these changes.

    • 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.
