I'm about to make conflicts also get materialized in executable
files. We'll lose some of the test coverage in `test_chmod_command.rs`
then, because the those tests rely on the materialized content to
describe the executable bits. So this commit adds a debug command for
printing tree values and uses that in the tests.
If we add glob support, users will probably want to do something like
'jj branch untrack glob:"*@origin"'. It would be annoying if the command
failed just because one of the remote branches has already been untracked.
Since branch tracking/untracking is idempotent, it's safe to continue in
those cases.
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*"'.
find_forgettable_branches() is unchanged for now. I might want to rewrite it
to not remove untracked remote branches (because untracked branches aren't
associated with the local counterparts.)
We need to let async-ness propagate up from the backend because
`block_on()` doesn't like to be called recursively. The conflict
materialization code is a good place to make async because it doesn't
depends on anything that isn't already async-ready.
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
This will be the option to include non-tracking remote branches. We could add
more fine-grained filtering flags, but I think --all is good enough and easier
to remember.
This patch also updates many of the test outputs to include synchronized remote
branches. I think verbose outputs will help catch future bugs.
This replaces our existing mechanism of adding `/.jj/` to
`.git/info/exclude` by adding `*` to `.jj/.gitignore`, as suggested by
@ppwwyyxx. That simplifies the code quite a bit, and it avoids the
problem with `.git/info/exclude` not existing (it apparently doesn't
exist when the user uses
https://git-scm.com/docs/git-init#_template_directory).
Closes#2385.
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.
Although this is logically correct, the error message is a bit cryptic. It's
probably better to reject push if non-tracking remote branches exist.
#1136
We'll use remote_ref.tracking_target() to classify push action, but not all
callers of local_remote_branches() need tracking_target() instead of target.
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.
Since pushed remote branches will share the common base targets with locals,
these branches should be marked as tracking. git::push_branches() will handle
that. It looks ugly that the public GitBranchPushTargets type keeps "force"-d
branches as a separate set, but we'll need to rework that anyway when we
implement --force-with-lease behavior. So let's leave it for now.
Some of the git::push_updates() tests have been migrated to the new function.
I left a couple of basic tests for git::push_updates() because push_updates()
will be used to implement a low-level "jj git push-refs" command.
This add support for custom `jj` binaries to use custom working-copy
backends. It works in the same way as with the other backends, i.e. we
write a `.jj/working_copy/type` file when the working copy is
initialized, and then we let that file control which implementation to
use (see previous commit).
I included an example of a (useless) working-copy implementation. I
hope we can figure out a way to test the examples some day.
This makes `Workspace::load()` look a new `.jj/working_copy/type` file
in order to load the right working copy implementation, just like
`Repo::load()` picks the right backends based on `.jj/store/type`,
`.jj/op_store/type`, etc. We don't write the file yet, and we don't
have a way of adding alternative working copy implementations, so it
will always be `LocalWorkingCopy` for now.
Our internal working copy implementations at Google will need the
commit so they can walk history backwards until they get to a "public"
commit. They'll then use that to tell build tools and virtual file
systems to present that as a base.
I'm not sure if we'll need to update `reset()` too. It's currently
only used by `jj untrack`, which doesn't change the commit's parent,
so it wouldn't affect any history walks.
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.
I'm not sure if this is the best way to render non-tracking branches, but
it helps to write CLI tests. Maybe we can add some hint or decoration to
non-tracking branches, but I'd like to avoid bikeshedding at this point.
Since we haven't migrated the push function yet, a deleted branch can be
pushed to non-tracking remotes. This will be addressed later.
#1136
I'm about to make `LockedLocalWorkingCopy` not borrow from
`LocalWorkingCopy`. That will make it easier to forget to update any
`LocalWorkingCopy` variables when the modifications have been
committed. This patch introduces a wrapper around
`LockedLocalWorkingCopy` to help prevent that.
Thanks to Yuya for the suggestion.
`LocalWorkingCopy::check_out()` can be expressed using the planned
`WorkingCopy` trait, so it doesn't need to be in the trait itself
`WorkingCopy`. I wasn't sure if I should make it a free function in
`working_copy`, but I ended up moving it onto `Workspace`.
This isn't important, but I'm going to change remote_targets to store RemoteRef
instead of RefTarget, so I went ahead and change the other field types as well.
We could fix do_git_clone() instead, but it seemed a bit weird that the
git_repo_path is relative to the store path which is unknown to callers.
Fixes#2374
There's a subtle behavior change. Unlike the original remove_remote_branch(),
remote_views entry is not discarded when the branches map becomes empty. The
reasoning here is that the remote view can be added/removed when the remote
is added/removed respectively, though that's not implemented yet. Since the
serialized data cannot represent an empty remote, such view may generate
non-unique content hash.
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.

The `TreeStateError` type is specific to the current local-disk
working-copy backend, so it should not be part of the generic
working-copy interface I'm trying to create.
