It seems very likely that we're going to remove support for open
commits, but it's still useful to have a `commit` command that lets
the user enter a description and starts a new change. Calling it
`commit` seems good to make the transition from other VCSs simpler.
The whole file is about the colocated case, where we automatically
import and export on every command, so there should be no reason to
call `git import` here.
The smoke test was useful a year ago, when our CLI test environment
was still annoying enough to use that there were very few tests. We
now have enough tests that the smoke test is not needed.
If I'm reading this attribute correctly, it says that if the
`map_first_last` feature is enabled, then we should enable the
`map_first_last` feature, which seems like it would not have any
effect. We started getting warnings from the nightly compiler about
this line because it tries to enable a feature that's stable in that
version.
Mercurial's test runner does something like this.
I considered replacing `\` by `/` everywhere, but we use `\` in
graph-log output quite frequently, so it doesn't seem worth it.
The idea is to (ab)use pest::error::Error type to pretty-print error
message with code span. pest::error::Error will be constructed upfront
to erase lifetime from Span<'i>/Position<'i>.
Baby step towards embedding matcher in RevsetExpression. If we had a fileset
language or regex pattern, we would probably want to parse it at this stage
so the syntax error can be reported without evaluation.
Use clap::Command::try_get_matches_from() to parse args, and handle the
resulting error as a CommandError. The exit code 2 matches the exit code that
clap would output (this is tested by test_alias).
With this new abstraction, teach the clap output to respect "ui.color"
(--color doesn't seem to be understood). We'll also make use of it when
we route output through the pager.
The "errors" returned by try_get_matches_from() can be found at
https://docs.rs/clap/latest/clap/error/enum.ErrorKind.html. I've tested:
- no args
- --help
- help subcommand
- --version
- subcommand with --help
- subcommand with bad args
This lets us write to stderr, but unlike write_error(), this won't write
with formatting. This will be used for preformatted strings, e.g. those
coming from clap.
If you remove all refs from the backing Git repo and then run `jj git
import`, we would see that all commits disappeared from the Git repo,
so we would remove them from the jj repo too. However, we do that by
doing a history walk from old heads to the new heads, which includes
the root commit when the new heads is an empty set. That means that we
mark the root commit as abandoned, which led to a crash in
`rewrite.rs` (when we try pick the root commit's first parent to use
as parent for rebased commits).
I was trying to create a reproduction script for #412, but the script
ran into another bug first. The script removed all the local and
remote branches from the backing Git repo. I noticed that we would
then try to abandon all commits. We should still count Git HEAD's
target as visible and not try to abandon it. This patch fixes that.
Sometimes a tagged commit is not in any branch on the remote, but we
should still consider them upstream and not include them in the
default log template.
This was reported by @colemickens but now that I think about it, I
remember seeing such commits in the Git core repo (v1.4.4.5 and a few
commits before it were never merged into main).
We don't have a good way of testing this because we don't have a
command for creating tags.
Closes#681
This was actually what I meant in my code-review comment but I used
the wrong word ("clip") :) I wasn't going to bother changing it, but
Clippy nightly just started warning about it.
