Subject: [PATCH v6 08/12] packfile-uri: support for excluding trees
Date: Tue, 19 Oct 2021 19:38:32 +0800	[thread overview]
Message-ID: <c7a885ebec703f383f5935517170b4ab755b5411.1634634814.git.tenglong@alibaba-inc.com> (raw)
In-Reply-To: <cover.1634634814.git.tenglong@alibaba-inc.com>

From: Teng Long <dyroneteng@gmail.com>

This commit introduce the exclusion of tree objects. The exclusion range
is designed by an enum named `exclude_level` in "pack-objects.c" that
enumerate three values, "ET_SELF", "ET_INCLUDE" and "ET_REACHABLE".

Exclusion scope on different level:

1. When a tree is specified to be excluded with level "ET_SELF",
only the tree object itself will be excluded.

2. When a tree specified to be excluded with level "ET_INCLUDE",
exclude the tree itself, as well as all the trees and blobs it contains.

3. When it is specified with level "ET_REACHABLE", the excluding scope
is as same as level "ET_INCLUDE", because tree do not have any
ancestors.
