Jujutsu v0.37.0

About

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

Release highlights

• A new syntax for referring to hidden and divergent change IDs is available: xyz/n where n is a number. For instance, xyz/0 refers to the latest version of xyz, while xyz/1 refers to the previous version of xyz. This allows you to perform actions like jj restore --from xyz/1 --to xyz to restore xyz to its previous contents, if you made a mistake.

  For divergent changes, the numeric suffix will always be shown in the log, allowing you to disambiguate them in a similar manner.

Breaking changes

• String patterns in revsets, command arguments, and configuration are now parsed as globs by default. Use substring: or exact: prefix as needed.

• remotes.<name>.auto-track-bookmarks is now parsed the same way they are in revsets and can be combined with logical operators.

• jj bookmark track/untrack now accepts --remote argument. If omitted, all remote bookmarks matching the bookmark names will be tracked/untracked. The old <bookmark>@<remote> syntax is deprecated in favor of <bookmark> --remote=<remote>.

• On Windows, symlinks that point to a path with / won't be supported. This path is invalid on Windows.

• The template alias format_short_change_id_with_hidden_and_divergent_info(commit) has been replaced by format_short_change_id_with_change_offset(commit).

• The following deprecated config options have been removed:

  • git.push-bookmark-prefix
  • ui.default-description
  • ui.diff.format
  • ui.diff.tool

• The deprecated commit_id.normal_hex() template method has been removed.

• Template expansion that did not produce a terminating newline will not be fixed up to provide one by jj log, jj evolog, or jj op log.

• The diff conflict marker style can now use \\\\\\\ markers to indicate the continuation of a conflict label from the previous line.

Deprecations

• The git_head() and git_refs() functions will be removed from revsets and templates. git_head() should point to the first_parent(@) revision in colocated repositories. git_refs() can be approximated as remote_bookmarks(remote=glob:*) | tags().

New features

• Updated the executable bit representation in the local working copy to allow ignoring executable bit changes on Unix. By default we try to detect the filesystem's behavior, but this can be overridden manually by setting working-copy.exec-bit-change = "respect" | "ignore".

• jj workspace add now also works for empty destination directories.

• jj git remote family of commands now supports different fetch and push URLs.

• [colors] table now supports dim = true attribute.

• In color-words diffs, context line numbers are now rendered with decreased intensity.

• Hidden and divergent commits can now be unambiguously selected using their change ID combined with a numeric suffix. For instance, if there are two commits with change ID xyz, then one can be referred to as xyz/0 and the other can be referred to as xyz/1. These suffixes are shown in the log when necessary to make a change ID unambiguous.

• jj util gc now prunes unreachable files in .jj/repo/store/extra to save disk space.

• Early version of a jj file search command for searching for a pattern in files (like git grep).

• Conflict labels now contain information about where the sides of a conflict came from (e.g. nlqwxzwn 7dd24e73 "first line of description").

• --insert-before now accepts a revset that resolves to an empty set when used with --insert-after. The behavior is similar to --onto.

• jj tag list now supports --sort option.

• TreeDiffEntry type now has a display_diff_path() method that formats renames/copies appropriately.

• TreeDiffEntry now has a status_char() method that returns single-character status codes (M/A/D/C/R).

• CommitEvolutionEntry type now has a predecessors() method which returns the predecessor commits (previous versions) of the entry's commit.

• CommitEvolutionEntry type now has a inter_diff() method which returns a TreeDiff between the entry's commit and its predecessor version. Optionally accepts a fileset literal to limit the diff.

• jj file annotate now reports an error for non-files instead of succeeding and displaying no content.

• jj workspace forget now warns about unknown workspaces instead of failing.

Fixed bugs

• Broken symlink on Windows. #6934.

• Fixed failure on exporting moved/deleted annotated tags to Git. Moved tags are exported as lightweight tags.

• jj gerrit upload now correctly handles mixed explicit and implicit Change-Ids in chains of commits (#8219)

• jj git push now updates partially-pushed remote bookmarks accordingly. #6787

• Fixed problem of loading large Git packfiles. https://github.com/GitoxideLabs/gitoxide/issues/2265

• The builtin pager won't get stuck when stdin is redirected.

• jj workspace add now prevents creating an empty workspace name.

• Fixed checkout of symlinks pointing to themselves or .git/.jj on Unix. The problem would still remain on Windows if symlinks are enabled. #8348

• Fixed a bug where jj would fail to read git delta objects from pack files. https://github.com/GitoxideLabs/gitoxide/issues/2344
