Subject: [PATCH 1/4] rev-list: refactor --missing=<missing-action>
Date: Thu, 18 Apr 2024 20:40:40 +0200 [thread overview]
Message-ID: <20240418184043.2900955-2-christian.couder@gmail.com> (raw)
In-Reply-To: <20240418184043.2900955-1-christian.couder@gmail.com>
Both `git rev-list` and `git pack-objects` support a
`--missing=<missing-action>` feature, but they currently don't share
any code for that.
In a following commit, we are going to add support for a similar
'missing-action' feature to another command. To avoid duplicating
similar code, let's start refactoring the rev-list code for this
feature into new "missing.{c,h}" files.
For now, this refactoring is about moving code from
"builtin/rev-list.c" into new "missing.{c,h}" files. But in a
following commit, that refactored code will be used in
`git pack-objects` too.
As `enum missing_action` and parse_missing_action_value() are moved to
"missing.{c,h}", we need to modify the later a bit, so that it stops
updating a global variable, but instead returns either -1 on error or
the parsed value otherwise.
