From: Ben Curtis <nospam@xxxxxxxxxx> 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@xxxxxxxxxxxxxxxxxxxxxxxxx/`, 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. Signed-off-by: Ben Curtis <nospam@xxxxxxxxxx> --- 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.
