[PATCH v4 07/19] repack: fix leaks on error with "goto cleanup"

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

 



Change cmd_repack() to "goto cleanup" rather than "return ret" on
error, when we returned we'd potentially skip cleaning up the
string_lists and other data we'd allocated in this function.
