2020-04-25commit-graph: close descriptors after mmapJeff King
We don't ever refer to the descriptor after mmap-ing it. And keeping it open means we can run out of descriptors in degenerate cases (e.g., thousands of split chain files). Let's close it as soon as possible. Signed-off-by: Jeff King <> Signed-off-by: Taylor Blau <> Signed-off-by: Junio C Hamano <>
2019-02-07fuzz-commit-graph: initialize repo objectJosh Steadmon
Various #DEFINE "constants" in commit-graph.c now depend on the_hash_algo->rawsz, but this object must be initialized before it can be used. Signed-off-by: Josh Steadmon <> Signed-off-by: Junio C Hamano <>
2019-01-16commit-graph, fuzz: add fuzzer for commit-graphJosh Steadmon
Break load_commit_graph_one() into a new function, parse_commit_graph(). The latter function operates on arbitrary buffers, which makes it suitable as a fuzzing target. Since parse_commit_graph() is only called by load_commit_graph_one() (and the fuzzer described below), we omit error messages that would be duplicated by the caller. Adds fuzz-commit-graph.c, which provides a fuzzing entry point compatible with libFuzzer (and possibly other fuzzing engines). Signed-off-by: Josh Steadmon <> Signed-off-by: Junio C Hamano <>
