parse_args() doesn't know all parameters needed to set up CommandHelper,
and we have to set StoreFactories later. That's okay for now, but I'm going
to add more parameters derived from CliRunner.
The next commit will move CommandHelper construction to the caller of
parse_args(). Without this change, parse_args() would have to return a tuple
of 3 elements, which seemed a bit too much.
This will be needed to test functionality for showing shortest
unique prefix for commit and change ids. As a bonus, this also
allows us to test log output with change ids.
As another bonus, this will prevent occasional CI failures like
https://github.com/martinvonz/jj/actions/runs/3817554687/jobs/6493881468.
This allows us to chain custom dispatch functions. If CommandHelper were
moved or passed by mutable reference, weird thing could happen depending
on the call order.
parse_args() will probably become more involved to deal with --config-toml,
-R, and repository configs. This builder will hopefully allow us to move
things around without changing the high-level interface.
I added support for using a vendored OpenSSL in dbadbd68c0. That was
in order to get the musl binary to work. However, it shouldn't be
needed on most platforms, and we've had a few reports of issues caused
by it. Let's disable it by default and enable it specifically when
building the musl binary instead.
Can be used with tools like taplo-lsp to show hints & validation in
editors/IDEs. Won't apply automatically to config files until it's
submitted to schemastore.org, but in the meantime it can be used via a
schema directive
(https://taplo.tamasfe.dev/configuration/directives.html#the-schema-directive)
or other manual config mechanism.
Context in #879.
I needed this in the course of debugging an error. Before this commit, the error looked like this:
```
Error: Unexpected error from backend: Object not found
```
After this commit, it looks like this:
```
Error: Unexpected error from backend: Object with CommitId 8f59646bc9bb6bb44b5624f1248f4a708f37003c not found: object not found - no match for id (8f59646bc9bb6bb44b5624f1248f4a708f37003c); class=Odb (9); code=NotFound (-3)
```
Strictly speaking, we could rely on e.g. `git2::Oid::from_str` to produce an error, but I figure that having an explicit error for a mismatching hash length might demystify some error condition in the future, since commit IDs and change IDs and potentially other backends' IDs may have different lengths, so this could flag a mismatch earlier/more obviously.
Since ui object is needed to report read_config() error, it makes sense to
create ui first without fallible user configuration. Ui::for_terminal() will
be replaced with this function and ui.reset(read_config()?).
Default::default() is also added to silence clippy. If we prefer, Ui::new()
can be replaced with Ui::default().
We forgot to actually call `StoreFactories::load_op_heads_store()` to
load the right type of `OpHeadsStore` depending on the contents of
`.jj/repo/op_heads/type`. That shouldn't have any effect yet since we
only have one type so far, and there are no out-of-tree types yet
either (clearly, since they would not work).
A file entry is represented as a Dirs of is_file flag set. This might seem
odd at this point, but allows us to remove special case from PrefixMatcher.
PrefixMatcher::new(&[RepoPath::root()]) will set is_file to the root entry.
