Users may try to run `jj workspace add <name>` without specifying a
path, which results in the workspace being created in the current
directory. This can be confusing, since the workspace contents will also
be snapshotted in the original workspace if it is not sparse. Adding a
warning should reduce confusion in this case.
The high level changes include:
- Reworking `fix_file_ids()` to loop over multiple candidate tools per file,
piping file content between them. Only the final file content is written to
the store, and content is no longer read for changed files that don't match
any of the configured patterns.
- New struct `ToolsConfig` to represent the parsed/validated configuration.
- New function `get_tools_config()` to create a `ToolsConfig` from a `Config`.
- New tests; the only old behavior that has changed is that we don't require
`fix.tool-command` if `fix.tools` defines one or more tools. The general
approach to validating the config is to fail early if anything is weird.

This allows tests to easily distinguish the effects of multiple formatters that
could be applied during a single `jj fix` command, which is helpful for testing
the feature for configuring multiple formatters on potentially overlapping
filesets.
Uppercase is a counterpart to lowercase. Append exposes the number of changes
and their order of execution in the file content, which provides a terse way of
writing test expectations.
This implements a building block of "signed-off-by line" #1399 and "commit
--verbose" #1946. We'll probably need an easy way to customize the diff part,
but I'm not sure if it can be as simple as a template alias function. User
might want to embed diffs without "JJ: " prefixes?
Perhaps, we can deprecate "ui.default-description", but it's not addressed in
this patch. It could be replaced with "default_description" template alias,
but we might want to configure default per command. Suppose we add a default
"backout_description" template, it would have to be rendered against the
source commit, not the newly-created backout commit.
The template key is named as "draft_commit_description" because it is the
template to generate an editor template. "templates.commit_description_template"
sounds a bit odd.
There's one minor behavior change: the default description is now terminated
by "\n".
Closes#1354
description_template_for_*() functions will be merged soon.
We don't need to set the default description to the second commit of the split
because its description should be kept empty if it was.
This could be handled by description_template_for_describe(), but I think it's
better to do mutation by caller. I also think commands like "backout" or "new"
can do a similar thing to generate a default commit description from the source
or merge parent commits.
This will help consolidate description_template_for_*() functions and port them
to templater. This change also means the committer (and operation start)
timestamp is set earlier. I think that's good.
This is part of migrating away from legacy trees (with path-level
conflicts). I can't think of any practical impact (we already compare
the tree ids equal).
This basically reverts 20eb9ecec1 "git: don't abandon HEAD commit when it
loses a branch." I think the new behavior is more consistent because the Git
HEAD is equivalent to @- in jj, so it shouldn't be considered a named ref.
Note that we've made old HEAD branch not considered at 92cfffd843 "git: on
external HEAD move, do not abandon old branch."
#4108
It's wrong to deduce loaded_at_head from command-line arguments if the repo was
loaded at an arbitrary operation. Instead, the caller should specify whether
the working copy state is synchronized with the repo view.
I think .for_loaded_repo(ui, workspace, repo, true) would be bad for
readability, so I added separate functions. I'm not happy with the name
.for_temporary_repo(), but it seems okay for the current call sites.
--at-op should be invalid on repo initialization. "init --ignore-working-copy"
could be supported by using working_copy.reset(), but I don't think it's
worth the effort. If the working directory is empty, --ignore-working-copy
is meaningless, and if the directory is not empty, the user would probably
want to do snapshot at some point.
I'm going to fix misuse of CommandHelper::for_loaded_repo(), which expects
that the given repo respects the --at-operation option.
I don't think all of the added tests are useful, but "clone
--ignore-working-copy" might be legit as a replacement for bare repos.
The user can define the setting `git.private-commits` as they desire. For
example:
git.private-commits = 'description(glob:"wip:*")'
If any commits are in this revset, then the push is aborted.
If a commit would be private but already exists on the remote, then it does
not block pushes, nor do its descendents block pushes unless they are also
contained in `git.private-commits`.
Closes#3376
If readonly_index() and index() returned Result, it would propagate to many
call sites. That seems bad for API ergonomics. Suppose most "repo" commands
depend on an index, I think it's okay to load index eagerly:
- "jj config" doesn't load repo (nor index)
- "jj workspace root" doesn't load repo (nor index)
- some other mutation commands load index when printing commit summary
- many other commands load index when resolving revset
In order to render description template, we'll need a Commit object that
represents the old state (with new tree and parents) before updating the
commit description. The added functions will help generate an intermediate
Commit object.
Alternatively, we can create an in-memory Commit object with some fake
CommitId. It should be lightweight, but might cause weird issue because the
fake id wouldn't be found in the store.
I think it's okay to write a temporary commit and rely on GC as we do for
merge trees. However, I should note that temporary commits are more likely to
be preserved as they are pinned by no-gc refs until "jj util gc".
This allows us to construct a builder, format description template with an
intermediate commit, then write() a final commit object to the repo.
I originally considered removing mut_repo from CommitBuilder at all, but
rewriter APIs rely on that CommitBuilder has &mut_repo, and splitting them
would make call sites uglier.
The inner builder methods are based on &mut Self instead of Self, because it's
easier to wrap, and users of the inner builder will bind it to a named variable
anyway.
