[PATCH v3 3/5] pack-objects: fix handling of multiple --filter options

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since 5cb28270a1 (pack-objects: lazily set up "struct rev_info", don't
leak, 2022-03-28) --filter options given to git pack-objects overrule
earlier ones, letting only the leftmost win and leaking the memory
allocated for earlier ones.  Fix that by only initializing the rev_info
struct once.
