Per discussion in https://github.com/martinvonz/jj/discussions/2555. I'm
okay with either way, but it's confusing if we had "branch create" and
"branch set" and both of these could create a new branch.
As discussed in Discord, it's less useful if remote_branches() included
Git-tracking branches. Users wouldn't consider the backing Git repo as
a remote.
We could allow explicit 'remote_branches(remote=exact:"git")' query by changing
the default remote pattern to something like 'remote=~exact:"git"'. I don't
know which will be better overall, but we don't have support for negative
patterns anyway.
Summary: A natural extension of the existing support, as suggested by Scott
Olson. Closes#2496.

Like "jj log PATHS...", unmatched name isn't an error. I don't think
"jj branch list glob:'push-*'" should fail just because there are no in-flight
PR branches.
Since "jj git fetch --branch" supports glob patterns, users would expect that
"jj git push --branch glob:.." also works.
The error handling bits are copied from "branch" sub commands. We might want to
extract it to a common helper function, but I haven't figured out a reasonable
boundary point yet.
AFAICT, all callers of `Merge::to_file_merge()` are already well
prepared for working with executable files. It's called from these
places:
* `local_working_copy.rs`: Materialized conflicts are correctly
updated using `Merge::with_new_file_ids()`.
* `merge_tools/`: Same as above.
* `cmd_cat()`: We already ignore the executable bit when we print
non-conflicted files, so it makes sense to also ignore it for
conflicted files.
* `git_diff_part()`: We print all conflicts with mode "100644" (the
mode for regular files). Maybe it's best to use "100755" for
conflicts that are unambiguously executable, or maybe it's better to
use a fake mode like "000000" for all conflicts. Either way, the
current behavior seems fine.
* `diff_content()`: We use the diff content in various diff
formats. We could add more detail about the executable bits in some
of them, but I think the current output is fine. For example,
instead of our current "Created conflict in my-file", we could say
"Created conflict in executable file my-file" or "Created conflict
in ambiguously executable file my-file". That's getting verbose,
though.
So, I think all we need to do is to make `Merge::to_file_merge()` not
require its inputs to be non-executable.
Closes#1279.
The parse rule is lax compared to revset. We could require the pattern to be
quoted, but that would mean glob patterns have to be quoted like 'glob:"foo*"'.
I personally don't mind if "jj branch list" showed all non-tracking branches,
but I agree it would be a mess if ~500 remote branches were listed. So let's
hide them by default as non-tracking branches aren't so interesting.
Closes#1136
We can provide more actionable error message than "not fast-forwardable". If
the push was fast-forwardable, "jj branch track" should be able to merge the
remote branch without conflicts, so the added step would be minimal.
This means that the commits previously pinned by remote branches are no longer
abandoned. I think that's more correct since "push" is the operation to
propagate local view to remote, and uninteresting commits should have been
locally abandoned.
This patch adds MutableRepo::track_remote_branch() as we'll probably need to
track the default branch on "jj git clone". untrack_remote_branch() is also
added for consistency.
Summary: This allows `workspace forget` to forget multiple workspaces in a
single action; it now behaves more consistently with other verbs like `abandon`
which can take multiple revisions at one time.
There's some hoop-jumping involved to ensure the oplog transaction description
looks nice, but as they say: small conveniences cost a lot.

Summary: Workspaces are most useful to test different versions (commits) of
the tree within the same repository, but in many cases you want to check out a
specific commit within a workspace.
Make that trivial with a `--revision` option which will be used as the basis
for the new workspace. If no `-r` option is given, then the previous behavior
applies: the workspace is created with a working copy commit created on top of
the current working copy commit's parent.

Before this patch, when updating to a commit that has a file that's
currently an ignored file on disk, jj would crash. After this patch,
we instead leave the conflicting files or directories on disk. We
print a helpful message about how to inspect the differences between
the intended working copy and the actual working copy, and how to
discard the unintended changes.
Closes#976.
I've added a boolean flag to the store to ensure that the migration never runs
more than once after the view gets "op restore"-d. I'll probably reorganize the
branches structure to support non-tracking branches later, but updating the
storage format in a single commit would be too involved.
If jj is downgraded, these "git" remote refs would be exported to the Git repo.
Users might have to remove them manually.
I have used the tree-level conflict format for several weeks without
problem (after the fix in 51b5d168ae). Now - right after the 0.10.0
release - seems like a good time to enable the config by default.
I enabled the config in our default configs in the CLI crate to reduce
impact on tests (compared to changing the default in `settings.rs`).
`jj split` with no arguments operates interactively, but I am nonetheless constantly running `jj split -i` because I expect an `--interactive` flag to exist for consistency.
However, `jj split <paths>` before this commit always operates non-interactively, so this commit has the nice practical effect that you can restrict your interactive splitting to a certain set of paths.
This adds a new `revset-aliases.immutable_heads()s` config for
defining the set of immutable commits. The set is defined as the
configured revset, as well as its ancestors, and the root commit
commit (even if the configured set is empty).
This patch also adds enforcement of the config where we already had
checks preventing rewrite of the root commit. The working-copy commit
is implicitly assumed to be writable in most cases. Specifically, we
won't prevent amending the working copy even if the user includes it
in the config but we do prevent `jj edit @` in that case. That seems
good enough to me. Maybe we should emit a warning when the working
copy is in the set of immutable commits.
Maybe we should add support for something more like [Mercurial's
phases](https://wiki.mercurial-scm.org/Phases), which is propagated on
push and pull. There's already some affordance for that in the view
object's `public_heads` field. However, this is simpler, especially
since we can't propagate the phase to Git remotes, and seems like a
good start. Also, it lets you say that commits authored by other users
are immutable, for example.
For now, the functionality is in the CLI library. I'm not sure if we
want to move it into the library crate. I'm leaning towards letting
library users do whatever they want without being restricted by
immutable commits. I do think we should move the functionality into a
future `ui-lib` or `ui-util` crate. That crate would have most of the
functionality in the current `cli_util` module (but in a
non-CLI-specific form).
I think the feature is requested by enough users that we should
include it by default, also for people who install from source (we
include it in the `packaging` feature already).
It increases the size of the binary from 16.5 MiB to 17.8 MiB. I
suspect we'd see some of that increase in size soon anyway, as I'm
probably going to use Tokio for making async backend requests.
Since e7e49527ef "git: ensure that remote branches never diverge", the last
known "refs/remotes" ref should be synced with the corresponding remote branch.
So we can always trust the branch@remote expression. We don't need "refs/tags"
lookup either since tags should have been imported by git::import_refs().
FWIW, I'm thinking of reorganizing view.git_refs() map as per-remote views.
It would be nice if we can get rid of revsets and template keywords exposing
low-level Git ref primitives.
This is a naive implementation, which cannot deal with multiple children
or parents stemming from merges.
Note: I gave each command separate a separate argument struct
for extensibility.
Fixes#878
Suppose "x::y" is the operator that defaults to "root()::visible_heads()"
respectively, "::" is identical to "all()". Since we've just changed the
behavior of "..y", ".." is now "root()..visible_heads()" meaning "~root()".
