The new parallel macOS linker reduces link time for the debug `jj` binary from
3s to 0.7s on my M2 Macbook Air, which is a significant reduction for nearly
no cost at all. This only assumes that you have a new enough Xcode environment
as your default (where `/usr/bin/ld` resides.)
This change requires Sonoma and Xcode 15, but in theory I think we could target
a lower macOS SDK version in order to produce binaries that are more backwards
compatible, so the only real cost is that developers who also use Nix would
require Sonoma.
This adds the basic outline of _when_ a Design Doc should be written. See the next
commit in the stack for the blueprint.
By adding this we hopefully can prevent unnecessary churn from new and longtime contributors,
when they want to add a major feature or rewrite a core part of Jujutsu. The text is written
as a guideline, not a rule.
Fixes#2476.
Previously, if there was a change id match within the short prefix
lookup set, `jj` would not look for commits with that same change id
outside the short prefix set. So, it wouldn't find the conflicted
commits for a commit with a divergent (AKA conflicted) change id.
It's common to create empty working-copy commits while using jj, and
currently the author timestamp for a commit is only set when it is first
created. If you create an empty commit, then don't work on a repo for a
few days, and then start working on a new feature without abandoning the
working-copy commit, the author timestamp will remain as the time the
commit was created rather than being updated to the time that work began
or finished.
This commit changes the behavior so that discardable commits (empty
commits with no description) by the current user have their author
timestamps reset when they are rewritten, meaning that the author
timestamp will become finalized whenever a commit is given a description
or becomes non-empty.
Now, the command for `jj git remote add` is `cmd_git_remote_add` and its
argument type is `GitRemoteAddArgs`. This should make it easier to find
the CLI docs and the implementation for commands.
This is how `jj branch` commands were already set up in this way. The
`jj op` commands were also already set up in this way, except the
functions are called e.g. `cmd_op_undo`, I kept this for simplicity.
I was mainly motivated by the `jj file` commands. Most other commands
had functions already named in the above pattern, but used to have
shorter argument type names.
We have two other kinds of working copies at Google and it's sometimes
useful to get the basic information about operation id and tree id for
them, for exampel for debugging stale workspaces. This patch adds a
command for that.
We could instead have made the old `jj debug working-copy` command
work for all kinds of working copies (like the new command) and only
have extra information for the standard local-disk implementation. I
don't feel strongly either way and could do it other other way instead
if people prefer that.
While explaining branch tracking behavior, I find it's bad UX that a deleted
branch can be re-"create"d with tracking state preserved. It's rather a "set"
operation. Since deleted tracking branch is still listed, I think it's better
to assume that the local branch name is reserved.
https://github.com/martinvonz/jj/discussions/3871
Renaming to deleted tracking branch is still allowed (with warning) because the
"rename" command can't handle tracked remotes very well. If it were banned, bad
rename couldn't be reverted by using "jj branch rename". It would be confusing
if "rename a b" succeeded with warning, but the following "rename b a" failed.
This will help inline view.remove_branch() in cmd_branch_forget(). I don't
care much about owned (String, _) vs (&str, _), but we can't simplify the
lifetime issue in find_forgettable_branches() anyway. So I made all callers
pass cloned Arc<ReadonlyRepo> and borrow (name, target) pairs from there.
Since we've split (local, remotes) branches to (locals, remotes { branches }),
.has_branch() API no longer makes much sense. Callers often need to check if
a remote branch is tracked.
It was convenient that expression nodes can be compared in tests, but no
equivalence property is needed at runtime. Let's remove Eq/PartialEq to
simplify the extension support.
Most of the tests are migrated to insta::assert_debug_snapshot!(). Some of them
could use assert_matches!(), but the resulting code would look ugly because of
nested RC<_>s.
We now have two `cmd_show` in the repo. I think this one should become
`cmd_file_show`, but this should be done uniformly over all the commands
for consistency.
I did *not* keep `print` as an alias (I couldn't find a compelling
reason to do it), but let me know if anyone feels like keeping it.
We don't want e.g. `jj diff --git` to have underlined text because
it's redundant there. This patch fixes that by adding a new `token`
label used only in the color-words diff (for now - it may be used in
git diffs in the future).
This means we could remove the `line_number` label but I left it
because there's little harm in having it and it seems like it can
still be useful.
Thanks to @yuja for noticing and suggesting the fix.
This is already included with the `ourRustVersion` expression since it includes
a complete Rust toolchain with all extensions.

If you want to set a background color on added/removed lines, you
currently get the same style on the line numbers. This patch lets you
specify a different style by overriding it on the line numbers.
We use `heads_ok()` for finding the head operations when there are
multiple current op heads. The current DFS-based algortihm needs to
always walk all the way to the root. That can be expensive when the
operations are slow to retrieve. In the common case where there are
two operations close to each other in the graph, we should be able to
terminate the search once we've reached the common ancestor. This
patch replaces the DFS by a BFS and adds the early termination.
Since "set <thing>" often adds a <thing> if not exists, it make some sense
that "branch set" does upsert. The current "branch set" use case is now covered
by "branch move", so it's okay to change the "set" behavior.
If new branch is created by "branch set", status message and hint will be
printed to help migration. The user should be able to undo creation if it was
a mistake.
Closes#3584
