Jujutsu's branches do not behave like Git branches, which is a major
hurdle for people adopting it from Git. They rather behave like
Mercurial's (hg) bookmarks.
We've had multiple discussions about it in the last ~1.5 years about this rename in the Discord,
where multiple people agreed that this _false_ familiarity does not help anyone. Initially we were
reluctant to do it but overtime, more and more users agreed that `bookmark` was a better for name
the current mechanism. This may be hard break for current `jj branch` users, but it will immensly
help Jujutsu's future, by defining it as our first own term. The `[experimental-moving-branches]`
config option is currently left alone, to force not another large config update for
users, since the last time this happened was when `jj log -T show` was removed, which immediately
resulted in breaking users and introduced soft deprecations.
This name change will also make it easier to introduce Topics (#3402) as _topological branches_
with a easier model.
This was mostly done via LSP, ripgrep and sed and a whole bunch of manual changes either from
me being lazy or thankfully pointed out by reviewers.
It's a pretty frequent request to have support for turning off
auto-tracking of new files and to have a command to manually track
them instead. This patch adds a `snapshot.auto-track` config to decide
which paths to auto-track (defaults to `all()`). It also adds a `jj
track` command to manually track the untracked paths.
This patch does not include displaying the untracked paths in `jj
status`, so for now this is probably only useful in colocated repos
where you can run `git status` to find the untracked files.
#323
It seems everyone agrees that `obslog` is not an intuitive name. There
was some discussion about alternatives in #3592 and on #4146. The
alternatives included `evolution`, `evolutionlog`, `evolog`,
`rewritelog`, `revlog`, and `changelog`. It seemed like
`evolution-log`/`evolog` was the most popular option. That also
matches the command's current help text ("Show how a change has
evolved over time").
The user can define the setting `git.private-commits` as they desire. For
example:
git.private-commits = 'description(glob:"wip:*")'
If any commits are in this revset, then the push is aborted.
If a commit would be private but already exists on the remote, then it does
not block pushes, nor do its descendents block pushes unless they are also
contained in `git.private-commits`.
Closes#3376
Some backends, like the one we have at Google, can restrict access to
certain files. For such files, if they return a regular
`BackendError::ReadObject`, then that will terminate iteration in many
cases (e.g. when diffing or listing files). This patch adds a new
error variant for them to return instead, plus handling of such errors
in diff output and in the working copy.
In order to test the feature, I added a new commit backend that
returns the new `ReadAccessDenied` error when the caller tries to read
certain objects.
It's been about six months since we started using tree-level conflicts
by default. I can't imagine we would switch back. So let's continue
the migration by always using tree-level conflicts when merging trees,
even if all inputs were legacy trees.
## 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.
Parallelize revisions by making them siblings
Running `jj parallelize 1::2` will transform the history like this:
```text
3
| 3
2 / \
| -> 1 2
1 \ /
| 0
0
```
Each of the target revisions is rebased onto the parents of the root(s) of
the target revset (not to be confused with the repo root). The children of
the head(s) of the target revset are rebased onto the target revisions.
The target revset is the union of the REVISIONS arguments.
The target revset being parallelized must satisfy several conditions,
otherwise the command will fail.
1. The heads of the target revset must not have different children.
2. The roots of the target revset must not have different parents.
3. The parents of all target revisions except the roots must also be
parallelized. This means that the target revisions must be connected.
this greatly speeds up the time to run all tests, at the cost of slightly larger recompile times for individual tests.
this unfortunately adds the requirement that all tests are listed in `runner.rs` for the crate.
to avoid forgetting, i've added a new test that ensures the directory is in sync with the file.
## benchmarks
before this change, recompiling all tests took 32-50 seconds and running a single test took 3.5 seconds:
```
; hyperfine 'touch lib/src/lib.rs && cargo t --test test_working_copy'
Time (mean ± σ): 3.543 s ± 0.168 s [User: 2.597 s, System: 1.262 s]
Range (min … max): 3.400 s … 3.847 s 10 runs
```
after this change, recompiling all tests take 4 seconds:
```
; hyperfine 'touch lib/src/lib.rs ; cargo t --test runner --no-run'
Time (mean ± σ): 4.055 s ± 0.123 s [User: 3.591 s, System: 1.593 s]
Range (min … max): 3.804 s … 4.159 s 10 runs
```
and running a single test takes about the same:
```
; hyperfine 'touch lib/src/lib.rs && cargo t --test runner -- test_working_copy'
Time (mean ± σ): 4.129 s ± 0.120 s [User: 3.636 s, System: 1.593 s]
Range (min … max): 3.933 s … 4.346 s 10 runs
```
about 1.4 seconds of that is the time for the runner, of which .4 is the time for the linker. so
there may be room for further improving the times.
