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).
Forgetting a workspace removes its working-copy commit, so it makes
sense for it to be abandoned if it is discardable just like editing a
new commit will cause the old commit to be abandoned if it is
discardable.
Currently, if two workspaces are editing the same discardable commit and
one of them switches to editing a different commit, it is abandoned even
though the other workspace is still editing it. This commit treats
workspaces as referencing their working-copy commits so that they won't
be abandoned.
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.
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's been more than 6 months since we added support for dynamically
selecting the working copy implementation. This patch drops support
for selecting the default implementation of that and other stores.
As we discovered in the `jj fix` tests,
`MergedTreeBuilder::write_tree()` doesn't try to resolve conflicts,
not even trivial ones. This patch fixes that.
Otherwise, newly created default branch would be re-imported as a new Git HEAD.
This could be addressed by cmd_git_init(), but the same situation can be
crafted by using "git checkout -b".
Some backends, like the one we have at Google, can restrict access to
certain files. For such files, if they return a regular
`BackendError::ReadObject`, then that will terminate iteration in many
cases (e.g. when diffing or listing files). This patch adds a new
error variant for them to return instead, plus handling of such errors
in diff output and in the working copy.
In order to test the feature, I added a new commit backend that
returns the new `ReadAccessDenied` error when the caller tries to read
certain objects.
Merge commits are very similar to non-merge commits in jj. An empty
merge commit with no description is not really different from an empty
non-merge commit with no description. As we discussed on
https://github.com/martinvonz/jj/issues/2859, we should not treat
merge commits differently when updating away from them. This patch
adds test for the current behavior (which is to leave the merge commit
in place).
I recently needed to test something on top of a two branches at the
same time, so I created a new commit on top of both of them (i.e. a
merge commit). I then ran tests and made some adjustments to the
code. These adjustments belonged in one of the parent branches, so I
used `jj squash --into` to squash it in there. Unfortunately, that
meant that my working copy became a single-parent commit based on one
of the branches only. We already had #2859 for tracking this issue.
This patch changes the behavior so we create a new working-copy commit
with all of the previous parents.
This should be a no-op, though that is not necessarily obvious in corner
cases.
Note that libgit2 already performs the push negotiation even when
pushing without force (without `+` in the refspec).
As explained in the commit, our logic is a bit more complicated than
that of `git push --force-with-lease`. This is to match the behavior of
`jj git fetch` and branch conflict resolution rules.
In chromium/src.git, this gives an approximate ~0.83s speedup for
commands if the Git index is empty, and a ~0.14s slowdown if the Git
index is non-empty.
As most users using jj will likely be using jj to write to a colocated
repo - and therefore avoid modifying the Git index - this should be a
general speedup for most colocated checkouts.
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.
This follows up on https://github.com/martinvonz/jj/pull/3459 and adds a
label to the closing delimeter of each conflict, e.g. "Conflict 1 of 3
ends".
I didn't initially put any label at the ending delimeter since the
starting delimeter is already marked with "Conflict 1 of 3". However,
I'm now realizing that when I resolve conflicts, I usually go from top
to bottom. The first thing I do is delete the starting conflict
delimeter. It is when I get to the *end* of the conflict that I wonder
whether there are any more conflicts left in the file.
The function now returns an iterator over `Result`s, matching
`Operation::parents()`.
I updated callers to also propagate the error where it was trivial.
For example,
```
<<<<<<< Conflict 1 of 3
+++++++ Contents of side #1
left 3.1
left 3.2
left 3.3
%%%%%%% Changes from base to side #2
-line 3
+right 3.1
>>>>>>>
```
or
```
<<<<<<< Conflict 1 of 1
%%%%%%% Changes from base to side #1
-line 3
+right 3.1
+++++++ Contents of side #2
left 3.1
left 3.2
left 3.3
>>>>>>>
```
Currently, there is no way to disable these, this is TODO for a future
PR. Other TODOs for future PRs: make these labels configurable. After
that, we could support a `diff3/git`-like conflict format as well, in
principle.
Counting conflicts helps with knowing whether you fixed all the
conflicts while you are in the editor.
While labeling "side #1", etc, does not tell you the commit id or
description as requested in #1176, I still think it's an improvement.
Most importantly, I hope this will make `jj`'s conflict format less
scary-looking for new users.
I've used this for a bit, and I like it. Without the labels, I would see
that the two conflicts have a different order of conflict markers, but I
wouldn't be able to remember what that means. For longer diffs, it can
be tricky for me to quickly tell that it's a diff as opposed to one of
the sides. This also creates some hope of being able to navigate a
conflict with more than 2 sides.
Another not-so-secret goal for this is explained in
https://github.com/martinvonz/jj/pull/3109#issuecomment-2014140627. The
idea is a little weird, but I *think* it could be helpful, and I'd like
to experiment with it.
The format is 7 characters of the separator followed by a space and arbitrary
text, followed by a newline. Separator followed by a newline is also allowed.
E.g.:
<<<<<<< Random text
%%%%%%% Random text
line 2
-line 3
+left
line 4
+++++++ Random text
right
%%%%%%% Random text
line 2
+forward
line 3
line 4
>>>>>>> Random text
This commit only allows reading such conflicts.
I considered allowing longer separators (`<<<<<<<<<<<<<< Random text`), but we
wouldn't currently write them, so let's be strict for now.
7 characters if they are followed by a space and arbitrary text
We already have two uses for this function and I think we're soon
going to have more.
The function record the old commit as abandoned with the new parents,
which is typically what you want. We could record it as abandoned with
the old parents instead but then we'd have to do an extra iteration to
find the parents when rebasing any children. It would also be
confusing if
`rewriter.set_parents(new_parents).record_abandoned_commit()` didn't
respect the new parents.
