Makes sure that, at the point the commit summary for the new commit is written,
the original commit that is being rewritten is already abandoned. Otherwise,
once we show divergent change ids (in a subsequent commit) in the short commit
template, the commits would be shown as divergent.
This also has an effect on whether branches are displayed next to the commit;
the changes in test_resotre_command happen because, now, the branch is properly
propagated to the restored commit before its summary is displayed.
I want to fix error propagation before I start using async in this
code. This makes the diff iterator propagate errors from reading tree
objects.
Errors include the path and don't stop the iteration. The idea is that
we should be able to show the user an error inline in diff output if
we failed to read a tree. That's going to be especially useful for
backends that can return `BackendError::AccessDenied`. That error
variant doesn't yet exist, but I plan to add it, and use it in
Google's internal backend.
Reasons to introduce this alias:
* Reduces complexity of a type, to silence Clippy warnings in the
future if we use this type as a type parameter
* The type is used quite frequently, so it makes sense to have a name
for it
* It's easier to visually scan for the end of the type when you don't
have to match opening and closing angle brackets
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.
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.
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.
