This is basically the same as Mercurial's workaround. I don't know about Git,
but arguments order is very restricted in git, so -C path can be parsed prior
to alias expansion. In hg and jj, doing that would be messy and unreliable.
Closes#2414
It should be better to handle invalid -R path globally. The error message is
a bit worse, but I think it's still okay.
This helps to load temporary config from the cwd-relative path. If the command
processing continued with an invalid -R path, the temporary config would have
to be explicitly discarded.
Make it clearer what the command does, make the error message when the file is
not ignored less of a surprise.
Also, I think it's nice to mention `.git/info/exclude`, since the path is
not trivial to remember.
As far as I can see in the chat, there's no objection to changing the default,
and git.auto-local-branch = false is generally preferred.
docs/branches.md isn't updated as it would otherwise conflict with #2625. I
think the "Remotes" section will need a non-trivial rewrite.
#1136, #1862
This is really a simple change that does the following in a transaction:
* Set the new branch name to point to the same commit as the old branch name.
* Set the old branch name to point to no commit (hence deleting the old name).
Before it starts, it confirms that the new branch name is not already in use.
I originally thought this would be unavoidable, but I was wrong. "jj git clone"
doesn't implicitly create any local branch if git.auto-local-branch is off, and
that's fine because the detached HEAD state is normal in jj.
That being said, Git users would expect that the main/master branch exists.
Since importing the default branch is harmless, let's create and track it no
matter if git.auto-local-branch is off.
It seems better to have the caller pass the transaction description
when we finish the transaction than when we start it. That way we have
all the information we want to include more readily available.
This tries to clarify the fact that the branches must be remote and the syntax
for specifying them as globs.

Here is the result (excerpt):
```
$ jj branch track --help
Start tracking given remote branches
A tracking remote branch will be imported as a local branch of the same name. Changes to it
will propagate to the existing local branch on future pulls.
Usage: jj branch track [OPTIONS] <BRANCH@REMOTE>...
Arguments:
<BRANCH@REMOTE>...
Remote branches to track
By default, the specified name matches exactly. Use `glob:` prefix to select
branches by wildcard pattern. For details, see
https://github.com/martinvonz/jj/blob/main/docs/revsets.md#string-patterns.
Examples: branch@remote, glob:main@*, glob:jjfan-*@upstream
```
default_index_store.rs is relatively big, and it contains types and impls in
arbitrary order. Let's split them into sub modules. After everything moved,
mod.rs will only contain tests.
This prints a hint about using `jj new <first conflicted commit>` and
`jj squash` to resolve conflicts. The hint is printed whenever there
are new or resolved conflicts.
I hope this hint will be useful especially for new users so they know
which commit to resolve conflicts in first. It may not be obvious that
they should start with the bottommost one. I hope the hint will also
be useful for more more experienced user by letting them just copy the
printed command without first running `jj log` to find the right
commit..
When e.g. `jj rebase` results in new conflicts, it's useful for the
user to learn about that without having to run `jj log` right
after. This patch adds reporting of new conflicts created by an
operation. It also add reporting of conflicts that were resolved or
abandoned by the operation.
There was no measurable performance impact when rebasing a single
commit in the Linux kernel repo.
Before, an absolute path would be saved in the git_target file if .git is a
symlink. That's not wrong, but seemed a bit weird. Let's consolidate the
behavior across .git file types.
Apparently, libgit2 doesn't deduce "core.bare" config from the directory name,
but gitoxide implements it correctly. So we shouldn't blindly canonicalize
the Git repository path. Fortunately, the saved git_target path isn't a fully-
canonicalized form (unless user explicitly sepcified "--git-repo ./.git"), so
we don't need a hack to remap git_target back to the symlink path.
is_colocated_git_workspace() is adjusted since the git_workdir is no longer
resolved from the fully-canonicalized repo path, at least in our code. Still we
have the ".git/.." fallback because test_init_git_colocated_symlink_gitlink()
would otherwise fail. I haven't figured out why, and the test might be actually
wrong compared to the git CLI behavior, but let's not change that for now.
Fixes#2668
A git repo created by the "repo" tool doesn't have core.base set, which means
the "bare"-ness relies on the directory name. Gitoxide appears to parse it
correctly, whereas libgit2 doesn't. That's why the symlinked .git repo is no
longer processed as a colocated repo.
#2668
This adds an initial `jj util gc` command, which simply calls `git gc`
when using the Git backend. That should already be useful in
non-colocated repos because it's not obvious how to GC (repack) such
repos. In my own jj repo, it shrunk `.jj/repo/store/` from 2.4 GiB to
780 MiB, and `jj log --ignore-working-copy` was sped up from 157 ms to
86 ms.
I haven't added any tests because the functionality depends on having
`git` binary on the PATH, which we don't yet depend on anywhere
else. I think we'll still be able to test much of the future parts of
garbage collection without a `git` binary because the interesting
parts are about manipulating the Git repo before calling `git gc` on
it.
See comments inline for details. Cc #2600.
In particular, I wanted to make sure these behaviors are not affected by #2646.
They don't seem to be.
The tests ended up weirder than expected because of
https://github.com/martinvonz/jj/issues/2600#issuecomment-1835418824. Even
though, right now, the behavior of tests is unaffected by that issue, the
*expected* behavior is different.
Branches move around a little confusigly with `abandon`. We do want to keep
them, to test their behavior, but we can show the change id to make things
clearer.
Each instance of the enum represents a single command, so singular
`*Command` seems better. That also seems to match the examples in
clap's documentation.
Note that one of the new tests panics; this is a newly discovered bug.
In Git, a commit's direct parent is allowed to also be an indirect ancestor
at the same time. `jj` currently tries to prevent this situation, but does
allow it. The correctness of `rebase -r A -d descendant_of_A` currently depends
on this jj-specific behavior; we should change that.
Cc #2600
Allowing `jj init --git` in an existing Git repo creates a second Git
store in `.jj/repo/store/git`, totally disconnected from the existing
Git store. This will only produce extremely confusing bugs for users,
since any operations they make in Git will *not* be reflected in the
jj repo.
This enables cheap str-to-RepoPath cast, which is useful when sorting and
filtering a large Vec<(String, _)> list by using matcher for example. It
will also eliminate temporary allocation by repo_path.parent().
