Subject: [PATCH 1/4] [GSOC] ref-filter: add obj-type check in grab contents
Date: Tue, 08 Jun 2021 14:37:59 +0000 [thread overview]
Message-ID: <48d256db5c349c1fa0615bb60d74039c78a831fd.1623163082.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.976.git.1623163082.gitgitgadget@gmail.com>
From: ZheNing Hu <adlternative@gmail.com>
Only tag and commit objects use `grab_sub_body_contents()` to grab
object contents in the current codebase. We want to teach the
function to also handle blobs and trees to get their raw data,
without parsing a blob (whose contents looks like a commit or a tag)
incorrectly as a commit or a tag.
Skip the block of code that is specific to handling commits and tags
early when the given object is of a wrong type to help later
addition to handle other types of objects in this function.
