This is the most notable shortcoming that --rebase-merges has, still,
relative to --preserve-merges' capabilities: it does not support passing
custom merge strategies or custom merge strategy options.
Let's fix this.
While working on this patch series, of course I tried to copy-edit the test
cases we have, to cover --preserve-merges' support for merge strategies. Oh
my, did I regret this decision as soon as my eyes set sight on
t3427-rebase-subtree.sh!
At first I tried my best to make heads or tails of t3427, for way too long.
In the end the only way to understand what the heck it tries to do was to
actually fix it. That's why this patch series looks as if it focuses on
t3427 rather than on adding support for custom merge strategies to the
--rebase-merges mode.
As a consolation to myself, this work was actually worth it, surprising as
that may look. Not only is t3427 now really easy to understand, adding that
test case for --rebase-merges -Xsubtree tickled the sequencer enough to
reveal a long-standing bug: the --onto option was simply ignored when passed
together with --rebase-merges and --root. For good measure, this patch
series addresses this bug, too.
Johannes Schindelin (12):
t3427: add a clarifying comment
t3427: simplify the `setup` test case significantly
t3427: move the `filter-branch` invocation into the `setup` case
t3427: condense the unnecessarily repetitive test cases into three
t3427: fix erroneous assumption
t3427: accommodate for the `rebase --merge` backend having been
replaced
t3427: fix another incorrect assumption
t3427: mark two test cases as requiring support for `git rebase -p`
rebase -r: support merge strategies other than `recursive`
t/lib-rebase: prepare for testing `git rebase --rebase-merges`
t3418: test `rebase -r` with merge strategies
rebase -r: do not (re-)generate root commits with `--root` *and*
`--onto`
