Subject: [PATCH] commit: replace rebase/sequence booleans with single pick_state enum
Date: Fri, 17 Jan 2020 13:45:05 +0000 [thread overview]
Message-ID: <pull.531.git.1579268705473.gitgitgadget@gmail.com> (raw)
From: Ben Curtis <nospam@nowsci.com>
In 116a408, the boolean `rebase_in_progress` was introduced by dscho to
handle instances when cherry-pick and rebase were occuring at the same time.
This created a situation where two independent booleans were being used
to define the state of git at a point in time.
Under his recommendation to follow guidance from Junio, specifically
`https://public-inbox.org/git/xmqqr234i2q0.fsf@gitster-ct.c.googlers.com/`,
it was decided that an `enum` that defines the state of git would be a
more effective path forward.
Tasks completed:
- Remove multiple booleans `rebase_in_progress` and `sequencer_in_use` and
replaced with a single `pick_state` enum that determines if, when
cherry-picking, we are in a rebase, multi-pick, or single-pick state
- Converted double `if` statement to `if/else if` prioritizing `REBASE` to
continue to disallow cherry pick in rebase.

commit: replaced rebase/sequence booleans with single pick_state enum
Addresses https://github.com/gitgitgadget/git/issues/426
Previous discussions from @dscho and Junio led to the decision to merge
two independent booleans into a single enum to track the state of git
during a cherry-pick leading to this PR/patch.
