This is another step towards allowing a custom `jj` binary to have its
own index type. We're going to have a server-backed index
implementation at Google, for example.
I'm about to make `RepoLoader::init()` return a `Result`, and I don't
want to have to wrap that in a new error in
`ReadonlyRepo::load_at_head()` since that's only used in tests.
It's been about 10 weeks and 730 commits since 0.6.0, compared to
about 7 weeks and 350 commits between 0.5.0 and 0.6.0, so it's time
for a new release. There's been significant user-visible changes and
code-quality improvements. Thanks, everyone!
We already have `create_random_commit()`, which returns a
`CommitBuilder`. Most callers directly write that to a
`MutableRepo`. That currently returns a `Commit`, but I'm about to
make it propagate errors from the backend. That would add an
`unwrap()` to this sequence, making it longer. Let's create a simple
helper for these callers to simplify this common pattern.
When you're done with the `CommitBuilder`, you're going to have to
call `write_to_repo()`, passing it a mutable `MutableRepo`
reference. It's a bit simpler to pass that reference when we create
the `CommitBuilder` instead, so that's what this patch does.
A drawback of passing in the mutable reference when we create the
builder is that we can't have multiple unfinished `CommitBuilder`
instance live at the same time. We don't have any such use cases yet,
and it's not hard to work around them, so I think this change is worth
it.
I ran an upgraded Clippy on the codebase. All the changes seem to be
about using variables directly in format strings instead of passing
them as separate arguments.
Let's acknowledge everyone's contributions by replacing "Google LLC"
in the copyright header by "The Jujutsu Authors". If I understand
correctly, it won't have any legal effect, but maybe it still helps
reduce concerns from contributors (though I haven't heard any
concerns).
Google employees can read about Google's policy at
go/releasing/contributions#copyright.
This makes the tests more hermetic, even though I don't think the
default values (taken from `whoami`) can break any tests (then we
would have already seen them break). Now we just need to make the
operation log's timestamps predictable and then we can start using
operation IDs in snapshot tests.
There are no "non-normal" files, so "normal" is not needed. We have
symlinks and conflicts, but they are not files, so I think just "file"
is unambiguous.
I left `testutils::write_normal_file()` because there it's used to
mean "not executable file" (there's also a `write_executable_file()`).
I left `working_copy::FileType::Normal` since renaming `Normal` there
to `File` would also suggest we should rename `FileType`, and I don't
know what would be a better name for that type.
The `testutils` module should ideally not be part of the library
dependencies. Since they're used by the integration tests (and the CLI
tests), we need to move them to a separate crate to achieve that.
