Subject: [PATCH] pack-bitmap: remove checks before bitmap_free
Date: Sun, 25 May 2025 05:09:43 +0000	[thread overview]
Message-ID: <pull.1977.git.git.1748149783383.gitgitgadget@gmail.com> (raw)

From: Lidong Yan <502024330056@smail.nju.edu.cn>

In pack-bitmap.c:find_boundary_objects, we build a roots_bitmap and
cascade it to cb.base. However, I’m wondering why we only free
roots_bitmap when the cascade succeeds. It seems we could safely remove
this check and always free roots_bitmap afterward, which might provide
some performance benefits.

    pack-bitmap: remove checks before bitmap_free
    
    In pack-bitmap.c:find_boundary_objects, remove cascade success check and
    always free roots_bitmap afterward to make static analysis tool works
    better.
