Currently, there is no way to disable these, this is TODO for a future
PR. Other TODOs for future PRs: make these labels configurable. After
that, we could support a `diff3/git`-like conflict format as well, in
principle.
Counting conflicts helps with knowing whether you fixed all the
conflicts while you are in the editor.
While labeling "side #1", etc, does not tell you the commit id or
description as requested in #1176, I still think it's an improvement.
Most importantly, I hope this will make `jj`'s conflict format less
scary-looking for new users.
I've used this for a bit, and I like it. Without the labels, I would see
that the two conflicts have a different order of conflict markers, but I
wouldn't be able to remember what that means. For longer diffs, it can
be tricky for me to quickly tell that it's a diff as opposed to one of
the sides. This also creates some hope of being able to navigate a
conflict with more than 2 sides.
Another not-so-secret goal for this is explained in
https://github.com/martinvonz/jj/pull/3109#issuecomment-2014140627. The
idea is a little weird, but I *think* it could be helpful, and I'd like
to experiment with it.
I considered adding RefTarget template type, but some of the methods naturally
fit to RefName. For example, a conflicted branch name is decorated as "??", so
it makes sense to add branch.conflict() instead of branch.target().conflict().
I'm not pretty sure how many RefName methods we'll need to add to port the
current branch listing, but there will be .tracked(), .tracking_local_present(),
.ahead_by(), and .behind_by().
I'm going to add more detailed output there. This is a step towards "branch
list" template. "tag list -T" wouldn't be that useful, but it shares primitives
with "branch list -T".
The `move_commits` function accepts a set of target commits to shift to
a new location given by `new_parents` and `new_children`. The roots of
the target set will be reparented onto `new_parents`. `new_children`
will then be reparented onto the heads of the target set.
The commits will be rebased in reverse topological order based on the
new set of parents of each commit, which avoids the need for multiple
sets of rebase operations.
When you use e.g. `git switch` to check out a conflicted commit,
you're going to end up with the `.jjconflicts-*` directories in your
working copy. It's probably not obvious what those mean. This patch
adds a README file to the root tree to try to explain to users what's
going on and how to recover.
The authoritative information about conflicts is stored in the
`jj:trees` commit header. The contents of conflicted commits is only
used for preventing GC. We can therefore add contents to the tree
without much consequence.
I will be updating `rebase -r` to avoid simplifying ancestor merges in a
subsequent commit, which will cause existing tests to fail for the Git
backend due to ancestor merges with the root commit.
I'm not sure if this was an intentional omission, but I think it would be
useful to have `-e` as a short flag for `--edit`. I don't usually edit commits,
but I do use `prev` and `next` with edit to navigate to a commit that I want to
squash. Often this is easier than typing `--from` and `--into` plus the change
IDs.
If people want to edit commits we shouldn't stand in their way.
This is following on the rewrite for `parallelize`.
- https://github.com/martinvonz/jj/pull/3521
Since rebase_descendants from rebase.rs is no longer used outside of that file,
it can be made private again.
In a future commit these tests will run with both `jj commit` and `jj new` since
both will have the same semantics for advancing the branch pointer.
Parameterizing the tests allows us to run both variants without duplicating the
test bodies. Since the commit IDs are different when `jj describe` + `jj new`
is used instead of `jj commit`, this commit also drops the commit IDs from the
test snapshots. This is fine because the commit IDs are not important for these
tests.
## Feature Description
If enabled in the user or repository settings, the local branches pointing to the
parents of the revision targeted by `jj commit` will be advanced to the newly
created commit. Support for `jj new` will be added in a future change.
This behavior can be enabled by default for all branches by setting
the following in the config.toml:
```
[experimental-advance-branches]
enabled-branches = ["glob:*"]
```
Specific branches can also be disabled:
```
[experimental-advance-branches]
enabled-branches = ["glob:*"]
disabled-branches = ["main"]
```
Branches that match a disabled pattern will not be advanced, even if they also
match an enabled pattern.
This implements feature request #2338.
This one just tests with a larger value and a human-readable string (10KB).

For new users this results in a significantly better error output, that
actually shows them how to solve the problem, and why it happened.

Previously, this command would work:
jj --config-toml='snapshot.max-new-file-size="1"' st
And is equivalent to this:
jj --config-toml='snapshot.max-new-file-size="1B"' st
But this would not work, despite looking like it should:
jj --config-toml='snapshot.max-new-file-size=1' st
This is extremely confusing for users.
This config value is deserialized via serde; and while the `HumanByteSize`
struct allegedly implemented Serde's `visit_u64` method, it was not called by
the deserialize visitor. Strangely, adding an `visit_i64` method *did* work, but
then requires handling of overflow, etc. This is likely because TOML integers
are naturally specified in `i64`.
Instead, just don't bother with any of that; implement a `TryFrom<String>`
instance for `HumanByteSize` that uses `u64::from_str` to try parsing the string
immediately; *then* fall back to `parse_human_byte_size` if that doesn't work.
This not only fixes the behavior but, IMO, is much simpler to reason about; we
get our `Deserialize` instance for free from the `TryFrom` instance.
Finally, this adjusts the test for `max-new-file-size` to now use a raw integer
literal, to ensure it doesn't regress. (There are already in-crate tests for
parsing the human readable strings.)

I'm going to make some `jj parallelize` cases that currently error out
instead be successful. Some of the will result in ancestor merges with
the root commit. This patch updates those tests to avoid that.
`jj parallelize` was a good example of a command that can be
simplified by the new API, so I decided to rewrite it as an example.
The rewritten version is more flexible and doesn't actually need the
restrictions from the old version (such as checking that the commits
are connected). I still left the check for now to keep this patch
somewhat small. A subsequent commit will remove the restrictions.
It was removed at 522025e091 "log: remove unused and inconsistent `log`
label", but obslog had the same inconsistency. Since it's now easy to label
the template output, let's re-add the "log" label.
The change in test_templater_upper_lower() is noop. Formatter no longer
emits reset sequence in the middle because the template is still labeled.
Mercurial appears to resolve cwd-relative path first, so "glob:*.c" could be
parsed as "**/*.c" if cwd was literally "**". It wouldn't practically matter,
but isn't correct. Instead, jj's parser first splits glob into literal part
and pattern. That's mainly because we want to parse the user input texts into
type-safe objects, and (RepoPathBuf, glob::Pattern) pairs are the simplest
ones. The current parser can't handle patterns like "foo/*/.." (= "foo" ?),
and errors out. I believe this restriction is acceptable.
Unlike literal paths, the 'glob:' pattern anchors to the whole file path. I
don't think "prefix"-matching glob is useful, and making it the default would
be rather confusing.
