I had intended for the `features = ["toml"]` to enable *only* the
`toml` feature, but I forgot to disable the default features so it had
no effect. This shrinks the binary from 17.4 MiB to 16.8 MiB.
Let WorkspaceCommandHelper clone it. WorkspaceCommandHelper could return
workspace_id by reference, but doing that would introduce noisy .clone()
calls and lifetime mess.
For consistency with the tree_state handling. This isn't that simple and
concise compared to the tree_state one, so I'm fine to drop the series.
I've extracted {operation_id, workspace_id} pair so these values can be
safely initialized by OnceCell. The extracted struct is named after the
"checkout" file.
As @huyz noticed, I accidentally lost the undo demo in 0d1bf7cb3b. I
also didn't update the working-copy demo. This patch fixes that by
updating all demos, so we also get the recent styling change from
af145c998ea4..
Here OnceCell<T> serves as RefCell<Option<T>>, but it doesn't require runtime
Ref/RefMut wrapper. This allows us to get rid of some .clone() calls needed to
hide Ref<_> from public interface.
I'll make TreeState::snapshot() return a boolean denoting whether tree_state
is updated or not. New tree_id can be obtained from TreeState, so let's
remove it from the return value.
While making tree_state() return RefMut<TreeState> instead of RefMut<Option<_>>,
I felt uncomfortable that tree_state(&self) returned a mutable reference. So
this patch splits it into tree_state() and tree_state_mut().
I was reading a draft of "Git Rev News: Edition 91" [1] where Peff
mentions some unfinished patches to allow negative timestamps in
Git. So I figured I should add support for that before I forget. I
haven't checked if libgit2 supports it, so it might be that our Git
backend still doesn't support it after this patch.

`pkgconfig` has been a alias to `pkg-config` since 2021-01-18, and has started being an error since 2022-09-24.
This commit makes recent nixpkgs versions work, but might make version older than January 2021 break (which is probably not an issue).
I changed the "GLOGAL OPTIONS" help heading to use title case, to
match clap's new help style.
I also removed our override of the help text for `-h, --help` because
the default text now includes "(use `-h` for a summary)" (and it's
harder override now).
Perhaps the most obvious difference to users will be the changed help
output
(https://epage.github.io/blog/2022/09/clap4/#polishing-help-output). It
no longer has color, and long lines are not wrapped. I suppose we
should wrap the text ourselves instead..
When the remote rejects a push, we now say something like this:
```
Remote rejected the update of some refs (do you have permission to push to ["refs/heads/main"]?)
```
That message could be formatted better, but this seems good enough for
now. We should probably have some more custom conversion from
`GitPushError` to `CommandError` in the CLI layer.
When we resolve aliases and we try to resolve something that is not a
real command and not an alias, we currently replicate `clap`'s error
message. I don't know why I did that because it seems that we should
just stop resolving aliases and let `clap` try to parse what we have
resolved at that point. This patch makes that change, thereby removing
an additional call to `process::exit()`.
This changes `RepoLoader` to take a map of functions that load a
specific type of backend, keyed by the backend type. The backend type
is read from `.jj/repo/store/backend`.
We currently determine if the repo uses the Git backend or the local
backend by checking for presence of a `.jj/repo/store/git_target`
file. To make it easier to add out-of-tree backends, let's instead add
a file that indicates which backend to use.
The `ReadonlyRepo::init_*()` functions were unused or used only in
tests. Let's remove them, thereby making the repo less aware of
specific backend implementations.
By calling `repo.loader()` on the existing repo, we reuse the same
commit store etc. That should make it easier to add out-of-tree
backends by removing one place we'd otherwise need to pass in a way of
creating a backend (now we reuse the instance that was already created
for the existing `repo`).
In many of these places, we don't need an owned value, so using a
reference means we don't force the caller to clone the value. I really
doubt it will have any noticeable impact on performance (I think these
are all once-per-repo paths); it's just a little simpler this way.
I feel it doesn't make sense for a simple getter function to create an
owned vec after 0108673087 "backend: let each backend handle root commit
on write."
