Subject: [PATCH v10 0/9] rebase: learn --keep-base and improvements on fast-forward behaviour
Date: Tue, 27 Aug 2019 01:37:43 -0400	[thread overview]
Message-ID: <cover.1566884063.git.liu.denton@gmail.com> (raw)
In-Reply-To: <cover.1566724236.git.liu.denton@gmail.com>

Thanks for your suggestions, Pratyush and Philip. I've incorporated both
of them into this reroll.


Changes since v1:

* Squashed old set into one patch
* Fixed indentation style and dangling else
* Added more documentation after discussion with Ævar

Changes since v2:

* Add testing for rebase --fork-point behaviour
* Add testing for rebase fast-forward behaviour
* Make rebase --onto fast-forward in more cases
* Update documentation to include use-case

Changes since v3:

* Fix tests failing on bash 4.2
* Fix typo in t3431 comment

Changes since v4:

* Make rebase --fork-point fast-forward in more cases

Changes since v5:

* Fix graph illustrations so that the "branch off" is visually in the
  correct place
* Refactor if-else in can_fast_forward into one-level-deep ifs to
  increase clarity

Changes since v6:

* Remove redundant braces around if
* Update comment around can_fast_forward call
* Add completion for rebase

Changes since v7:

* Ævar sent in his WIP patchset

Changes since v8:

* Drop patches 9-13
* Fix some minor whitespace issues from v7

Changes since v9:

* Remove unnecessary if-statement in patch 6/9
* Update commit message for patch 9/9 for clarity according to Philip's
  suggestions
