Author dates and committer dates can be filtered like so:
committer_date(before:"1 hour ago") # more than 1 hour ago
committer_date(after:"1 hour ago") # 1 hour ago or less
A date range can be created by combining revsets. For example, to see any
revisions committed yesterday:
committer_date(after:"yesterday") & committer_date(before:"today")
The text pattern is applied prior to comparison as we do in Mercurial. This
might affect hunk selection, but is much faster than computing diff of full
file contents. For example, the following hunk wouldn't be caught by
diff_contains("a") because the line "b\n" is filtered out:
- a
b
+ a
Closes#2933
Since fileset and revset languages are syntactically close, we can reparse
revset expression as a fileset. This might sound a bit scary, but helps
eliminate nested quoting like file("~glob:'*.rs'"). One oddity exists in alias
substitution, though. Another possible problem is that we'll need to add fake
operator parsing rules if we introduce incompatibility in fileset, or want to
embed revset expressions in a fileset.
Since "file(x, y)" is equivalent to "file(x|y)", the former will be deprecated.
I'll probably add a mechanism to collect warnings during parsing.
Adds support for revset functions `tracked_remote_branches()` and
`untracked_remote_branches()`. I think this would be especially useful
for configuring `immutable_heads()` because rewriting untracked remote
branches usually wouldn't be desirable (since it wouldn't update the
remote branch). It also makes it easy to hide branches that you don't
care about from the log, since you could hide untracked branches and
then only track branches that you care about.
Maybe it'll also be good to keep RevsetExpression::Union(_) flattened, but
that's not needed to get around stack overflow. The constructed expression
tree is balanced.
test_expand_symbol_alias() is slightly adjusted since there are more than
one representation for "a|b|c" now.
Fixes#4031
Partially resolve a 1.5‐year‐old TODO comment.
Add opt‐in syntax for case‐insensitive matching, suffixing the
pattern kind with `-i`. Not every context supports case‐insensitive
patterns (e.g. Git branch fetch settings). It may make sense to make
this the default in at least some contexts (e.g. the commit signature
and description revsets), but it would require some thought to avoid
more confusing context‐sensitivity.
Make `mine()` match case‐insensitively unconditionally, since email
addresses are conventionally case‐insensitive and it doesn’t take
a pattern anyway.
This currently only handles ASCII case folding, due to the complexities
of case‐insensitive Unicode comparison and the `glob` crate’s lack
of support for it. This is unlikely to matter for email addresses,
which very rarely contain non‐ASCII characters, but is unfortunate
for names and descriptions. However, the current matching behaviour is
already seriously deficient for non‐ASCII text due to the lack of any
normalization, so this hopefully shouldn’t be a blocker to adding the
interface. An expository comment has been left in the code for anyone
who wants to try and address this (perhaps a future version of myself).
This revset correctly implements "reachability" from a set of source commits following both parent and child edges as far as they can go within a domain set. This type of 'bfs' query is currently impossible to express with existing revset functions.
Suppose the generation value is usually small, it should be faster to do
bounded range look up first 'y-', then walk ancestors with the unwanted set
'y-..x'.
Initially we were thinking to have `Revset` return something like
`CachedRevset`:
```
pub trait CachedRevset {
fn iter(&self) -> Box<dyn Iterator<Item = Commit>>;
fn contains(&self, &CommitId) -> bool;
}
```
But we weren't sure what use case for `iter` would be, so we dropped the `iter`
method. `CachedRevset` with single `contains` method needed a better name. We
weren't able to come up with one, so we decided instead to have a method on
`Revset` that returns a closure to check if a commit is in a revset.
This is #3002 with tests rerun to account for changes
to `strsim`, as @thoughtpolice noticed in
https://github.com/martinvonz/jj/pull/3002#issuecomment-1936763101
The string similarity changes include an example that
seems better and one that seems worse. Decreasing
the threshold definitely makes things worse.
I plan to replace `Revset::change_id_index()` by
`Index::change_id_index(heads)`, but one of the tests currently uses a
set of commits that does not include ancestors. This patch updates it
to include ancestors (and changes the set of heads to keep the set
small enough for the test).
This isn't technically needed, but it prevents API misuse. Another option
is to do some compile-time substitution, but most callers are tests and the
runtime performance wouldn't matter.
I'm going to add a prefix resolution method to OpStore, but OpStore is
unrelated to the index. I think ObjectId, HexPrefix, and PrefixResolution can
be extracted to this module.
It seems better to have the caller pass the transaction description
when we finish the transaction than when we start it. That way we have
all the information we want to include more readily available.
This enables cheap str-to-RepoPath cast, which is useful when sorting and
filtering a large Vec<(String, _)> list by using matcher for example. It
will also eliminate temporary allocation by repo_path.parent().
`RevsetExpression::resolve()` is meant for programmatically created
expressions. In particular, it may not contain symbols. Let's try to
clarify that by renaming the function and documenting it.
As discussed in Discord, it's less useful if remote_branches() included
Git-tracking branches. Users wouldn't consider the backing Git repo as
a remote.
We could allow explicit 'remote_branches(remote=exact:"git")' query by changing
the default remote pattern to something like 'remote=~exact:"git"'. I don't
know which will be better overall, but we don't have support for negative
patterns anyway.
The state field isn't saved yet. git import/export code paths are migrated,
but new tracking state is always calculated based on git.auto-local-branch
setting. So the tracking state is effectively a global flag.
As we don't know whether the existing remote branches have been merged in to
local branches, we assume that remote branches are "tracking" so long as the
local counterparts exist. This means existing locally-deleted branch won't
be pushed without re-tracking it. I think it's rare to leave locally-deleted
branches for long. For "git.auto-local-branch = false" setup, users might have
to untrack branches if they've manually "merged" remote branches and want to
continue that workflow. I considered using git.auto-local-branch setting in the
migration path, but I don't think that would give a better result. The setting
may be toggled after the branches got merged, and I'm planning to change it
default off for better Git interop.
Implementation-wise, the state enum can be a simple bool. It's enum just
because I originally considered to pack "forgotten" concept into it. I have
no idea which will be better for future extension.
Since set_remote_branch_target() is called while merging refs, its tracking
state shouldn't be reinitialized. The other callers are migrated to new setter
to keep the story simple.
I don't think the backend should matter for any of these tests, so
let's test with only one, and let's make that the strictest one - the
new test backend.
This reduces the number of tests by 74 (from 974 to 900), but saves no
measurable run time.
It makes the call sites clearer if we pass the `TestRepoBackend` enum
instead of the boolean `use_git` value. It's also more extensible (I
plan to add another backend for tests).
Since e7e49527ef "git: ensure that remote branches never diverge", the last
known "refs/remotes" ref should be synced with the corresponding remote branch.
So we can always trust the branch@remote expression. We don't need "refs/tags"
lookup either since tags should have been imported by git::import_refs().
FWIW, I'm thinking of reorganizing view.git_refs() map as per-remote views.
It would be nice if we can get rid of revsets and template keywords exposing
low-level Git ref primitives.
