Lataa jj 0.44.0

About
jj is a Git-compatible version control system that is both simple and powerful. See
the installation instructions to get started.

Release highlights
- Support for fetching and pushing tags has now been stabilized. Tags can be
tracked or untracked just like bookmarks. Tracked tags are pushed by default.

Breaking changes
- jj git fetch now fetches tags the same way it fetches bookmarks. Tags are
fetched as <name>@<remote>, and these remote tags are automatically tracked
by local tags of the same name. Running jj git fetch in an existing
repository will re-fetch all tags to initialize the tracking state.
Git's tagOpt is no longer respected. To disable tag fetching, set
remotes.<name>.fetch-tags = '~*' in the jj configuration.
- jj git clone --fetch-tags=all|none|included is removed in favor of
--tag=PATTERN.
- jj git push --all now pushes all tags in addition to bookmarks.
- The WorkspaceRef.root() and RepoPath.absolute() template functions now
return Option<FsPath> and FsPath respectively, instead of String. The
path keyword in jj config list templates now returns Option<FsPath>.
- jj file search now prints every matched line prefixed by the file path,
instead of only the file paths of files containing a match. Use
--name-only for the previous behavior.
#9399
- Passing an argument more than once is no longer an error. The last occurrence
wins, so jj --no-pager --no-pager version and jj log -n 5 -n 10 now work,
and an argument baked into an alias or a wrapper can be given explicitly as
well. Arguments that can be specified multiple times, such as --config and
jj log -r, are unaffected and still collect all of their values.

#9859

Deprecations
None

New features
- New merge_point() revset function which (similar to fork_point) finds the
point where multiple branches merge.
- jj workspace list now shows workspace roots by default. The output can be
customized with templates.workspace_list or -T, and WorkspaceRef.root()
returns an optional FsPath value.
#9713,
#9826
- New try(expr, fallback...) template function to suppress runtime errors.
- jj run now processes revisions from oldest to newest by default. The start
order is guaranteed: each revision begins execution only after the previous
one has started, even with --jobs higher than 1.
- jj run gained a --passthrough flag that connects the subprocess's
stdout/stderr directly to the terminal instead of capturing output.
- jj run gained a --ignore-changes flag to avoid editing any revisions even
if the command modifies the working copy.
- jj run gained a --ignore-errors flag to continue running against the
remaining revisions even if the command exits with a nonzero exit code.
- jj file search now supports -n/--line-number to prefix each match with
its 1-based line number within the file.
- jj git push gained a --allow-conflicts flag to allow pushing commits
containing conflicts.
- New jj tag track/untrack commands to associate local tags with remotes.
Note that fetched tags are tracked by default.
- Added builtin_log() revset alias for the built-in default jj log revset.
revsets.log now defaults to builtin_log(), so custom log revsets can
reuse the built-in default instead of copying its full expression.
- Added config option diff.stat.max-bar-width for use with --stat to limit
the ++-- bar width. In the templating language, diff.stat() can optionally
take a second (positional or named) argument max_bar_width for an equivalent
effect.
- jj absorb now supports --interactive/-i/--tool to let you
interactively choose which hunks from the source to consider for absorption.
This is useful when you only want to absorb part of a commit without first
splitting it. Any hunks that are not selected or cannot be absorbed remain in
the source commit.

Fixed bugs
- Recursive alias definitions are detected more precisely. jj can now expand
aliases that are simply repeated. For example, with the alias jj = [], the
command jj jj jj will resolve to jj. Aliases can also fall back to the
default command. For example, with the alias i = ["--ignore-working-copy"],
jj i will resolve to jj --ignore-working-copy.
- Git temporary files are now cleaned up more reliably in the presence of
signals (e.g. Ctrl-C). This should reduce the rate of "Could not acquire
lock for index file" errors.
(#7530)
- Fixed Git HEAD mismatch after the working copy became immutable.
#9827
- jj now creates a new working-copy revision as soon as the one of the current
workspace becomes immutable, as well as during snapshotting. This brings the
behavior closer to jj 0.42 and earlier.
- Snapshotting no longer fails if the working copy contains a path whose name
isn't valid UTF-8. Such paths can't be tracked, so they are now skipped and
reported as a warning instead.
#9774
- Fixed failure when reading configuration in copied repo with an empty
repo-level configuration directory.
- jj diff and jj status no longer omit a rename or copy in a merge commit
when the renamed source is present in more than one parent. The identical copy
record reported for each parent was mistaken for a conflict and discarded.
#9752
- jj run no longer panics when its revset includes a conflicted commit. The
conflict is now preserved in the rewritten commit.
#9747
- Fixed a panic when passing overly-large length parameters to ID templater
functions (commit_id.short(), commit_id.shortest(), etc.).
#9833
- jj git import and export in colocated workspaces are now disabled by
default. These commands usually do nothing, but they had a race condition.
