When editing a commit, the index of the current commit can change; for example,
when merge commits are involved, or when working with stacked branches where
"update-ref" commands may be added above the selected commit.
Reselect the current commit after pressing "e"; this requires doing the refresh
blocking on the main thread. (Another option that I considered was to use a
SYNC refresh, and then select the new line with an OnUIThread inside the Then
function. This also works, but results in a very visible lag.)
This is useful for when you begin to type the message in lazygit's commit panel,
and then realize that you'd rather use your editor's more powerful editing
capabilities. Pressing <c-o> will take you right there.
It determines the yellow/red status by getting the merge-base between the
current branch and its upstream; while we're rebasing, the current branch is
HEAD, so it tried to get the merge-base between HEAD and HEAD{u}, which doesn't
work. Fix this by passing the name of the checked-out branch separately.
This also fixes a bug where after the rebase each commit in the commits view had a tick against it because we hadn't
refreshed the view since the base commit was no longer marked
This was on oversight on my part: I assumed that the --work-tree arg was
always intended for use with linked worktrees which have a .git file
pointing back to the repo.
I'm honestly confused now: seems like there are three kinds of worktrees:
* the main worktree of a non-bare repo
* a linked worktree (with its own gitdir in the repo's worktrees/ dir)
* a random folder which you specify as a worktree with the --work-tree arg
I'm pretty sure the --work-tree arg is only intended to be used with this
third kind or workree
The proper fix is to actually have these two functions share code,
or for views to be able to manage their own heights based on their contents.
But I want to get this out for the sake of a Lazygit Anniversary release.
Now that we refresh upon focus, we can scrap this file watching code.
Stefan says few git UIs use file watching, and I understand why: the
reason this code was problematic in the first place is that watching
files is expensive and if you have too many open file handles that
can cause problems.
Importantly: this code that's being removed was _already_ dead.
This allows to do the equivalent of "git rebase --onto <target> <base>", by
first marking the <base> commit with the new command, and then selecting the
target branch and invoking the usual rebase command there.
We want to mark all local branch heads with a "*" in the local commits panel, to
make it easier to see how branches are stacked onto each other. In order to not
confuse users with "*" markers that they don't understand, do this only for the
case where users actually use stacked branches; those users are likely not going
to be confused by the display. This means we want to filter out a few branch
heads that shouldn't get the marker: the current branch, any main branch, and
any old branch that has been merged to master already.
We've been sometimes using lo and sometimes using my slices package, and we need to pick one
for consistency. Lo is more extensive and better maintained so we're going with that.
My slices package was a superset of go's own slices package so in some places I've just used
the official one (the methods were just wrappers anyway).
I've also moved the remaining methods into the utils package.
In the presentation layer, when showing branches, we'll show worktrees against branches if they're
associated. But there was a race condition: if the worktree model was refreshed after the branches model,
it wouldn't be used in the presentation layer when it came time to render the branches.
A better solution would be to have some way of signalling that a particular context needs to be refreshed
and after all the models are done being refreshed, we then refresh the contexts. This will prevent
double-renders
There are quite a few paths you might want to get e.g. the repo's path, the worktree's path,
the repo's git dir path, the worktree's git dir path. I want these all obtained once and
then used when needed rather than having to have IO whenever we need them. This is not so
much about reducing time spent on IO as it is about not having to care about errors every time
we want a path.
We now always re-use the state of the repo if we're returning to it, and we always reset the windows to their default tabs.
We reset to default tabs because it's easy to implement. If people want to:
* have tab states be retained when switching
* have tab states specific to the current repo retained when switching back
Then we'll need to revisit this
Older versions of git don't support the -z flag in `git worktree list`.
So we're using newlines.
Also, we're not raising an error upon error because that triggers another refresh,
which gets us into an infinite loop
