This is useful for copying the entire content of the selected file as it was at
the selected commit.
We only add it to the commit files panel; it is not needed in the files panel,
because there you can simply press "e" to edit the file.
Rewording a commit at the beginning of a long branch can take very long;
without this change, the commit message panel would stay visible with a blinking
cursor during that time, which is very confusing.
This has the slight downside that it will say "Rebasing" in the lower right
corner until the operation is done; but we already have this problem when doing
custom patch operations, or dropping changes from a commit, so it's not new, and
we can think about how to fix all these another time.
This includes the "only conflicting" status that the user can't switch to
themselves. We display it anyway to give a hint that files are being filtered,
and to let them know that they can turn the filter off if they want to.
I renamed the "Reset filter" item to "No filter" to make it look more like a
state than an action, so that it fits the radio button concept better.
When there are conflicts and we set the filter to show only conflicting files,
then none of the radio buttons light up, which is slightly strange. I guess it's
ok though.
This handles the situation where the user's own config says to not show
untracked files, as is often the case with bare repos managing a user's
dotfiles.
Git diff and patch doesn't work reliably with a context size of 0, so disable it
in this case (and discarding changes as well). Magit does the same, see
https://github.com/magit/magit/issues/4222.
Staging entire files by pressing space in the Files panel is still possible, of
course.
When the user checks out a commit which has a local branch ref attached
to it, they can select between checking out the branch or checking out
the commit as detached head.
For non-merge commits we change "pick" to "drop" when we delete them. We do this
so that we can use the same code for dropping a commit no matter whether we are
in an interactive rebase or not. (If we aren't, we could just as well delete the
pick line from the todo list instead of setting it to "drop", but if we are, it
is better to keep the line around so that the user can change it back to "pick"
if they change their mind.)
However, merge commits can't be changed to "drop", so we have to delete them
from the todo file. We add a new daemon instruction that does this.
We still don't allow deleting a merge commit from within an interactive rebase.
The reason is that we don't show the "label" and "reset" todos in lazygit, so
deleting a merge commit would leave the commits from the branch that is being
merged in the list as "pick" commits, with no indication that they are going to
be dropped because they are on a different branch, and the merge commit that
would have brought them in is gone. This could be very confusing.
Not much of a change in behavior, because moving merge commits was already not
possible. However, it failed with a cryptic error message ("Todo fa1afe1 not
found in git-rebase-todo"), so disable it properly instead.
We allow deleting remote branches (or local and remote branches) only if *all*
selected branches have one.
We show the a warning about force-deleting as soon as at least one of the
selected branches is not fully merged.
The added test only tests a few of the most interesting cases; I didn't try to
cover the whole space of possible combinations, that would have been too much.
When creating a PR against a selected branch (via O = "create pull request
options"), the user will first be asked to select a remote (if there is more
than one). After that, the suggestion area is populated with all remote branches
at that origin - instead of all local ones. After all, creating a PR against a
branch that doesn't exist on the remote won't work.
Please note that for the "PR is not filed against 'origin' remote" use case
(e.g. when contributing via a fork that is 'origin' to a GitHub project that is
'upstream'), the opened URL will not be correct. This is not a regression and
will be fixed in an upcoming PR.
Fixes#1826.
In other views that show lists of commits (reflog and stash) it doesn't make
sense to show a range diff of selected entries because they don't form a linear
sequence, so we keep the previous behavior of showing the diff for the free end
of the selection range in those view.
The same applies to the commits view if the selection range includes rebasing
todos; these can have an arbitrary order, and a range diff doesn't make sense
for those.
