Subject: [PATCH v7 0/6] pack-redundant: new algorithm to find min packs
Date: Wed, 30 Jan 2019 19:47:30 +0800
Message-ID: <20190130114736.30357-1-worldhello.net@gmail.com> (raw)
In-Reply-To: <20190112091754.30985-1-worldhello.net@gmail.com>

Sun Chao (my former colleague at Huawei) found a bug of
git-pack-redundant.  If there are too many packs and many of them
overlap each other, running `git pack-redundant --all` will
exhaust all memories and the process will be killed by kernel.

There is a script in commit log of commit 3/6, which can be used to
create a repository with lots of redundant packs. Running `git
pack-redundant --all` in it can reproduce this issue.

Add new test cases in t5323 for better test coverage.

## Changes since reroll v6

* Add new test cases in t5323.

* Add new patch 2/6 (pack-redundant: delay creation of unique_objects), 
  which will fix a bug which fail to find redundant packs if turn on alt-odb
  searching with `--alt-odb` option.  This is because alt-odb objects are
  only remove in unique_objects fields but not in all_objects fields of
  pack_list.
