There have been a number of users confused about why
their commits are immutable, or what to do about it, ex.
[https://github.com/jj-vcs/jj/discussions/5659].
Separately, I feel that the cli is too quick to suggest
`--ignore-immutable`, without context of the consequences. A new user
could see that the command is failing, see a helpful hint to make it not
fail, apply it and move on. This has wildly different consequences, from
`jj squash --into someone_elses_branch@origin` rewriting a single commit,
to `jj edit 'root()+'` rewriting your entire history.
This commit changes the immutable hint by doing the following:
* Adds a short description of what immutable commits are used for, and a
link to the relevant docs, to the hint message.
* Shows the number of immutable commits that would be rewritten if
the operation had succeeded.
* Removes the suggestion to use `--ignore-immutable`.
Previously, tools invoked by `jj fix` did not have their
`.current_dir()` set, and would just run from whatever directory the
user was in.
Now, the tools will always be invoked from the same directory that
`jj root` gives.
As a motivating example, consider a configuration path that's always at
the workspace root:
```toml
[fix.tools.something]
# previous:
command = ["cmd", "--config", "$root/tool.toml"]
# ^^^^^^ not possible
# now:
command = ["cmd", "--config", "./tool.toml"]
# ^^ now, just use a relative path
```
Aliases and `ui.default-command` are loaded before `--config` and
`--config-file` arguments are parsed (#5282).
There is supposed to be a warning when the result of these arguments
would change the parsed args: #5286.
However, that warning was not being printed if the arguments failed to
parse due to an unrecognized subcommand. Example:
```bash
# correct:
$ jj --config ui.default-command=nonsense
Warning: Command aliases cannot be loaded from -R/--repository path or --config/--config-file arguments.
# previous, confusing:
$ jj --config aliases.some-alias=nonsense some-alias
error: unrecognized subcommand 'some-alias'
# now:
$ jj --config aliases.some-alias=nonsense some-alias
Warning: Command aliases cannot be loaded from -R/--repository path or --config/--config-file arguments.
error: unrecognized subcommand 'some-alias'
```
Move the `track` specific logic to track.rs, let print_snapshot_stats
handle just the default case.
Previously print_snapshot_stats would get called twice and could warn
twice about a file (if that file was both in the auto-track fileset as
well as in the fileset passed to `jj file track`), so now we merge the
snapshot stats and display appropriate hints for each file.
Snapshot stats were automatically printed when calling
`WorkspaceCommandHelper::snapshot_working_copy`. This has been moved up
the call chain to allow more choice in when to actually print stats.
These functions used to trigger printing of the snapshot stats via
(direct or indirect) calls to `snapshot_working_copy`:
- CommandHelper::workspace_helper_with_stats
- CommandHelper::recover_stale_working_copy
- WorkspaceCommandHelper::maybe_snapshot_impl
This means we can now chose not to print the snapshot stats if we know
we will perform another snapshot operation during the same command, to
reduce the number of warnings and hints shown to the user.
Calling `workspace_helper`, or `maybe_snapshot` instead of
`workspace_helper_with_stats` and `maybe_snapshot_impl` still prints
stats automatically.
This should help prevent misuse of "jj bookmark set" with e.g. remote bookmark
name. A remote-looking bookmark can be created by quoting the name if needed.
This patch doesn't change the parsing of name patterns. For patterns, I think
it's better to add support for compound expressions (e.g. `glob:foo* & ~bar`)
rather than adding revset::parse_string_pattern(text) -> StringPattern.
Closes#5705
These helpers are going to be needed to port the git2 code in the lib
tests to gitoxide. Since the cli tests already depend on testutils, this
helps with avoiding duplicating the code
It's easier to review insta snapshot diffs than scanning panic log containing
lengthy output. I think this will also help printf debugging.
test_global_opts.rs is migrated to new API as an example.
The "conflict" label is supposed to highlight "(conflict)" markers in commit
template. This patch just removes the label as we don't colorize the same
message in update_working_copy().
I'm going to add "[EOF]" marker to test that command output is terminated by
newline char. This patch ensures that callers who expect a raw output string
would never be affected by any normalization passes.
Some common normalization functions are extracted as CommandOutputString
methods.
Although this behaviour is accepted by git, it's a degenerate case.
Especially because we implicitely rely on being able to parse out the
remote from the refname (i.e., `refs/remotes/<remote>/<branch>`).
Branches can have forward slashes, but if remotes can also have them,
parsing the refname becomes ambiguous, and a pain. Especially because it
would be totally legal to have a branch "c" on remote "a/b" and a branch
"b" on remote "a".
Fixes#5731
In the case where the user has set `snapshot.auto-track` to something
other than `all()`, running `jj st` with a higher file size set just for
that command will not actually fix the user's problem, `jj file track`
needs to be called instead.
Some working-copy implementations, like the Google CitC one, may want
to update the VFS's state even if the tree didn't change. In
particular, when updating between two commits with the same tree but
different mainline base, we want to update the base commit. Otherwise
a future snapshot, which we do relative to the mainline commit, may
notice an incorrect set of changed file.
