This solves three problems:
1. When the local main branch is behind its upstream, the merged status of
commits of a feature branch sitting on origin/main was not correct. This can
easily happen when you rebase a branch onto origin/main instead of main, and
don't bother keeping local main up to date.
2. It works when you don't have the main branch locally at all. This could
happen when you check out a colleague's feature branch that goes off of
"develop", but you don't have "develop" locally yourself because you normally
only work on "main".
3. It also works when you work on a main branch itself, e.g. by committing to it
directly, or by merging a branch locally. These local commits on a main
branch would previously be shown in green instead of red; this broke with
910a61dc46.
For consistency with the previous commit.
Note that this menu entry is used both for unstaged and for staged changes, and
for staged changes it is not quite accurate, as we are not discarding changes in
that case (just unstaging them). Not sure it's worth fixing this; it's still
better than "Delete", anyway.
The title was saying "Unstage lines", which was just wrong. The text said
"Delete lines", which can be seen as a bit misleading; we are only discarding
the changes to the selected lines, not deleting the lines themselves.
For consistency, rename the config variable skipUnstageLineWarning accordingly.
The assert package is already very good at displaying errors, including printing
a diff of expected and actual value, so there's no point in printing the same
information again ourselves.
This test is almost identical to swap_in_rebase_with_conflict.go, except that it
sets the commit that will conflict to "edit".
This test is interesting because there's special code needed to determine
whether an "edit" command conflicted or not, i.e. whether to show the "confl"
entry. In this case we do. We have lots of other tests already that have "edit"
commands that don't conflict, so that's covered already.
When stopping in a rebase because of a conflict, it is nice to see the commit
that git is trying to apply. Create a fake todo entry labelled "conflict" for
this, and show the "<-- YOU ARE HERE ---" string for that one (in red) instead
of for the real current head.
This test is interesting because it already behaves as desired: since git has
rescheduled the "pick" command, we do _not_ want to show a "conflict" entry in
this case, as we would see the same commit twice then.
We don't actually use it to do map lookups; we still iterate over it in the same
way as before. However, using a map makes it easier to patch elements; see the
next commit.
We use CommitFilesController also for the files of commits that we show
elsewhere, e.g. for branch commits, tags, or stashes. It doesn't make sense to
discard changes from those (for stashes it might be possible to implement it
somehow, but that would be a new feature), so we disallow it unless we are in
the local commits panel.
Discarding changes to an entire directory doesn't quite work correctly in all
cases; for example, if the current commit added files to the directory (but the
directory existed before) then those files won't be removed.
It might be possible to fix the command so that these cases always work for
directories, but I don't think it's worth the effort (you can always use a
custom patch for that), so let's display an error for now.
I don't know why we were setting the initial context to CurrentSideContext
and not just CurrentContext in the first place. If there is no current context
in either case it'll default to the files context. So the only issue is if
we anticipated that some random context would be focused and we didn't want to
activate that. But I can't think of any situation where that would happen.
Whenever we perform an action in a test, we should assert on the result before doing the next action.
This prevents issues where the test moves too fast for our code. It would be nice to not have to do this,
but for now that's the situation
A better refactor would be to allow matchers to assert against either a string or a slice of cells, so that I could have
the same ergonomics that I have elsewhere, but this is a start.
