I noticed that some config structures do not use their "Default" implementation, and have their default specified in a TOML file. I think specifying defaults in TOML is great, and it'd be good to delete those Default implementations, so that it does not diverge from the default in the TOML file.
There's only one non-test caller who doesn't need a complete map of rebased
commits.
FWIW, I tried to rewrite squash_commits() based on transform_descendants() API,
but it wasn't easy because of A-B+A=A rule. The merge order matters here.
Tag and bookmark names are usually ASCII, but they occasionally include Latin
or Han characters.
This doesn't fix the serialization problem, but should mitigate #5359.
The "identifier" rule will be changed to accept unicode characters. It's not
super important to reject non-ASCII string pattern prefixes or alias symbols,
but this is more consistent with templater and fileset. We can relax the rule
later if needed.
This is a middle ground. An inline table can still be overwritten or deleted
because it's syntactically a value. It would be annoying if "jj config set
colors.<name> '{ .. }'" couldn't be executed more than once because the existing
item was a table.
#5255
Instead of resolving deprecated variables by callers or config object, this
patch adds a function that rewrites deprecated variables globally (and emits
warnings accordingly.) It's simpler because StackedConfig doesn't have to deal
with renamed variables internally. OTOH, warnings will be issued no matter if
variables are used or not, which might be a bit noisy.
Maybe we can also add "jj config migrate" command that updates user and repo
configs.
I have come to think of conflicts more and more as one positive
followed by a series of diffs and less as two separate sets of adds
and removes. We've already changed the implmentation of `Merge` to be
a single list of interleaved positive and negative terms. I think it's
simpler to use the same format in `trivial_merge()` too.
To keep the diff simple, I just preserved the test case values and
order as is for now even if that means that some of them are now
unintuitive. I'll clean that up in the next commit.
If many files are conflicted, it would be nice to be able to resolve all
conflicts at once without having to run `jj resolve` multiple times.
This is especially nice for merge tools which try to automatically
resolve conflicts without user input, but it is also good for regular
merge editors like VS Code.
This change makes the behavior of `jj resolve` more consistent with
other commands which accept filesets since it will use the entire
fileset instead of picking an arbitrary file from the fileset.
Since we don't support passing directories to merge tools yet, the
current implementation just calls the merge tool repeatedly in a loop
until every file is resolved, or until an error occurs. If an error
occurs after successfully resolving at least one file, the transaction
is committed with all of the successful changes before returning the
error. This means the user can just close the editor at any point to
cancel resolution on all remaining files.
There are some experiments to try and compile `jj` to WebAssembly, so that we
might be able to do things like interactive web tutorials. One step for that
is making `git` support in `jj-cli` optional, because we can stub it out for
something more appropriate and it's otherwise a lot of porting annoyance for
both gitoxide and libgit2.
(On top of that, it might be a useful build configuration for other experiments
of mine where removing the need for the large libgit2 depchain is useful.)
As part of this, we need to mark `jj-lib` as having `default-features = false`
in the workspace dependency configuration; otherwise, the default behavior
for Cargo is to compile with all its default features, i.e. with git support
enabled, ignoring the `jj-cli` features clauses.
Other than that, it is fairly straightforward junk; it largely just sprinkles
some `#[cfg]` around liberally in order to make things work. It also adjusts the
CI pipeline so this is tested there, too, so we can progressively clean it up.

`zstd` is only used to write files in the native backend right now. For now,
jettison it, to unbundle some C code that we don't really need.
(Ideally, a future compression library would be pure Rust, but we'll cross that
bridge when we get to it...)

This backs out commit 0de36918e4. Documentation,
tests, and comments are updated accordingly. I also add ConfigTableLike type
alias as we decided to abstract table-like items away.
Closes#5255
If the parent tree contains conflicts, we want the index to also contain
a conflict to ensure that the use can't accidentally commit conflict
markers using `git commit`. Since we can't represent conflicts with more
than 2 sides in the Git index, we need to add a dummy conflict in this
case. We use ".jj-do-not-resolve-this-conflict" as the dummy conflict to
indicate to the user that they should not attempt to resolve this
conflict using Git.
Instead of setting the index to match the tree of HEAD, we now set the
index to the merged parent tree of the working copy commit. This means
that if you edit a merge commit, it will make the Git index look like it
would in the middle of a `git merge` operation (with all of the
successfully-merged files staged in the index).
If there are any 2-sided conflicts in the merged parent tree, then they
will be added to the index as conflicts. Since Git doesn't support
conflicts with more than 2 sides, many-sided conflicts are staged as the
first side of the conflict. The following commit will improve this.
This will give us more fine-grained control over what files we put in
the index, allowing us to create conflicted index states. We also still
need to use git2 to clean up the merge/rebase state, since gix doesn't
have any function for this currently.
These tests should still pass after we switch to gix for resetting the
index, so we need to make sure they don't rely on the cached index from
the `git2::Repository` instance.
Disclaimer: this is the work of @necauqua and @julienvincent (see
#3141). I simply materialized the changes by rebasing them on latest
`main` and making the necessary adjustments to pass CI.

I had to fix an issue in `TestSignatureBackend::sign()`.
The following test was failing:

Print debugging revealed that the signature was bad, because of a
missing trailing `\n` in `TestSignatureBackend::sign()`.

We need to make `TestSigningBackend` available for cli tests, as we will
add cli tests for signing related functionality (templates for
displaying commit signatures, `jj sign`) in upcoming commits.
