Add gratuitous `jj log` output to more points in the tests.
This makes it easier to understand the intended changes
by literally visualizing the commit tree we are after each movement.
This is at least useful for me since I find the new+squash workflow
confusing.
Test behaviour is not changed.
Part of #3947
We all noticed that x86 macOS binaries are no longer being provided on release,
due to `macos-11` runners going the way of the Dodo a while back. Nobody
alterted us to this, funny enough.
After some quick discussion, we concluded some things:
- x86 macOS runners are likely oversubscribed, and hurt CI latency badly
- `macos-12` is also deprecated; `macos-13` is the best x86 runner available
- GitHub probably isn't going to expand macOS runner capacity; `macos-13` will
one day go away
- Some people are still using `jj` on Intel Macs. We didn't get alerted because
they do their own builds for now, but may not always do that.
- We can just try to build on `macos-13` and make it optional for merges.
So that's what this does. It might be mergeable outright, but we can also use it
to measure build latency impacts.

I'm thinking of adding some heuristics to render hunks containing lots of
small word changes differently, in a similar manner to the unified diffs. This
patch might help add some pre/post-processing at consumer.
files::diff() is inlined to caller to get around 'self borrowing.
When rebasing a new child commit on top of the moved commit(s), the
order of the new child commit's parent commits is now correctly
preserved if the original parent commit is now a parent of the moved
commit(s).
Closes#3969.
I think they were adding too much noise to commit diffs. Only the tests
focused on skipping rebasing will include the commit and change IDs,
other tests will omit them.
* Add `builtin_immutable_heads()` in the `revsets.toml`.
* Redefine `immutable_heads()` in terms of `builtin_immutable_heads()`
* Warn if user redefines `builtin_immutable_heads()`, `mutable()` or
`immutable()`.
* Update module constant in revset_util.rs from BUILTIN_IMMUTABLE_HEADS
to USER_IMMUTABLE_HEADS to avoid confusion since it points at
`immutable_heads()` **and** we now have a revset-alias
literally named `builtin_immutable_heads()`.
* Add unittest
* Update CHANGELOG
* Update documentation.
Fixes: #4162
- add support for copy tracking to `diff --stat`
- switch `--summary` to match git's output more closely
- rework `show_diff_summary` signature to be more consistent
Add home directory expansion for SSH key filepaths. This allows the
`signing.key` configuration value to work more universally across both
Linux and macOS without requiring an absolute path.
This moved and renamed the previous `expand_git_path` function to a more
generic location, and the prior use was updated accordingly.
Perhaps, we should also cache merged trees, but this patch saves time until
we implement the bookkeeping. Even if we had a cache, it wouldn't be ideal to
calculate uncached merged trees during revset evaluation.

I'll add conflict resolution there.
This change adds more synchronization points, which is probably bad for
concurrency. However, this module is a revset engine for the default index,
so the store backends are supposed to be fast local disks.
I'll add a public function that resolves file conflicts. This function will
take owned MergedTreeValue, and that's why the extracted function returns
None instead of cloning the passed value.
MergedTreeVal was roughly equivalent to Merge<Option<Cow<_>>. As we've dropped
support for the legacy trees, it can be simplified to Merge<Option<&_>>.
try_resolve_file_conflict() is also updated. It could be a generic function,
but there are only two callers, and the legacy tree one is used only in tests.
For the same reason as 2cb7e91d "merged_tree: do not re-look up non-conflicting
tree values by name." This appears to bring a similar performance improvement.
I assume this change is/will be covered by test_merged_tree.rs. I considered
adding a few unit tests, but constructing Tree object isn't trivial, and the
iterator implementation is relatively straightforward.
- force each diff command to explicitly enable copy tracking
- enable copy tracking in diff_summary
- post-process for diff iterator
- post-process for diff stream
- update changelog
