This helps add library API that takes resolved revset expressions. For example,
"jj absorb" will first compute annotation within a user-specified ancestor range
such as "mutable()". Because the range expression may contain symbols, it should
be resolved by caller.
There are two ideas to check resolution state at compile time:
<https://github.com/martinvonz/jj/pull/4374>
a. add RevsetExpressionWrapper<PhantomState> and guarantee inner tree
consistency at public API boundary
b. parameterize RevsetExpression variant types in a way that invalid variants
can never be constructed
(a) is nice if we want to combine "resolved" and "unresolved" expressions. The
inner expression types are the same, so we can just calculate new state as
Resolved & Unresolved = Unresolved. (b) is stricter as the compiler can
guarantee invariants. This patch implements (b) because there are no existing
callers who need to construct "resolved" expression and convert it to "user"
expression.
.evaluate_programmatic() now requires that the expression is resolved.
Custom backends may rely on networking or other unreliable implementations to support revsets, this change allows them to return errors cleanly instead of panicking.
For simplicity, only the public-facing Revset and RevsetGraph types are changed in this commit; the internal revset engine remains mostly unchanged and error-free since it cannot generally produce errors.

It's split into "op_log operation" and just "operation" for the
summaries (as suggested by Yuya). The color labels use "operation".
This patch replaces all call sites with present(trunk()), and adds an explicit
check for unresolvable trunk(). If we add coalesce() expression, maybe it can
be rewritten to coalesce(present(trunk()), builtin_trunk()).
Fixes#4616
Check if only the email or the name are missing in the config and specifically name the missing one, instead of always defaulting to potentially both missing.
Stacking at AliasExpanded node looks wonky. If we migrate error handling to
Diagnostics API, it might make sense to remove AliasExpanded node and add
node.aliases: vec![(id, span), ..] field instead.
Some closure arguments are inlined in order to help type inference.
* See #4239 for details.
* For now, update working copy before reporting repo changes, so that
potential errors in reporting changes don't leave the repo in a stale
state.
Fixes: #4239
Deprecation warnings will be printed there. auto_tracking_matcher(ui) could
be cached, but there aren't many callers right now, so it should be okay to
parse and emit warnings for each invocation. Other than that, the changes are
straightforward.
I'll make parse_<language>_template() require &Ui, but these cached templates
should be re-constructible without access to a Ui.
Maybe we can split a parsed template object into RevsetExpression-like
evaluation tree and interpreter environment, but that'll be a big challenge.
This will help simplify warning handling in future patches. I'm going to add
deprecation warnings to revset, so Ui will be required in order to parse a user
revset expression.
revset_util::parse_immutable_expression() is inlined as it's a thin wrapper
around parse_immutable_heads_expression().
This is basically "log -p" for "op log". The flag name has "op" because --diff
and --patch mean a similar thing in this context. Since -p implies --op-diff,
user can just do "op log -p" if he's okay with verbose op + content diffs.
Note that --no-graph affects both "op log" and "op diff" parts.
We might want to do some style changes later, such as inserting/deleting blank
lines, highlighting headers, etc.
Multiple graphs will be nested in "op log" output, and things would be messy if
we had to calculate graph widths lazily. Let's simply make LogContentFormat
track the current available width no matter if ui.log-word-wrap is off.
Jujutsu's branches do not behave like Git branches, which is a major
hurdle for people adopting it from Git. They rather behave like
Mercurial's (hg) bookmarks.
We've had multiple discussions about it in the last ~1.5 years about this rename in the Discord,
where multiple people agreed that this _false_ familiarity does not help anyone. Initially we were
reluctant to do it but overtime, more and more users agreed that `bookmark` was a better for name
the current mechanism. This may be hard break for current `jj branch` users, but it will immensly
help Jujutsu's future, by defining it as our first own term. The `[experimental-moving-branches]`
config option is currently left alone, to force not another large config update for
users, since the last time this happened was when `jj log -T show` was removed, which immediately
resulted in breaking users and introduced soft deprecations.
This name change will also make it easier to introduce Topics (#3402) as _topological branches_
with a easier model.
This was mostly done via LSP, ripgrep and sed and a whole bunch of manual changes either from
me being lazy or thankfully pointed out by reviewers.
I'll use a similar setup in "op log", but for each log entry. We might want to
extract some parts to helper function, but I don't have a good idea right now.
CommandHelper::operation_template_extensions() is removed because it's unlikely
to parse operation template without loading a workspace.
I'll add an option to include diffs in "op log", and workspace_env will be used
in order to set up diff/template contexts per operation.
cmd_op_log() is split because of owned/borrowed type differences.
These functions will be used by "op log"/"diff"/"show".
This patch also changed the error type as it's obvious that there are no other
errors to be returned.
It doesn't make sense to reparse revset expression. Let's reuse the parse
result. This also simplifies error handling bits.
OnceCell is switched to the std one as we no longer need get_or_try_init().
Some "operation" commands need a workspace, plus multiple repo views. We
currently load WorkspaceCommandHelper twice for that reason. It works, but
would be messy if "op log" loaded WorkspaceCommandHelper for each log entry.
This patch starts splitting non-repo data from WorkspaceCommandHelper. The
workspace object isn't owned by the environment object so the object can be
freely discarded.
It's a pretty frequent request to have support for turning off
auto-tracking of new files and to have a command to manually track
them instead. This patch adds a `snapshot.auto-track` config to decide
which paths to auto-track (defaults to `all()`). It also adds a `jj
track` command to manually track the untracked paths.
This patch does not include displaying the untracked paths in `jj
status`, so for now this is probably only useful in colocated repos
where you can run `git status` to find the untracked files.
#323
We had both `repo()` and `mut_repo()` on `Transaction` and I think it
was easy to get confused and think that the former returned a
`&ReadonlyRepo` but both of them actually return a reference to
`MutableRepo` (the latter obviously returns a mutable reference). I
hope that renaming to the more idiomatic `repo_mut()` will help
clarify.
We could instead have renamed them to `mut_repo()` and
`mut_repo_mut()` but that seemed unnecessarily long. It would better
match the `mut_repo` variables we typically use, though.
This avoids cloning `UserSettings` and some other data. I haven't
attempted to measure the performance impact (I expect it's tiny); this
is more about clarifying that there are not multiple different
versions of these fields.
This wraps all the fields in `CommandHelper` in an `Rc` so
`CommandHelper` itself becomes cheap to clone (thanks to @yuja for the
idea). I'll use that next to avoid some cloning in
`WorkspaceCommandHelper`.
"Concurrent" operations are not necessarily actually concurrent, so
"divergent" seems like a better name. And "reconcile" seems like a
better term for merging them, though we also sometimes use "merge".
