When pushing a branch that didn't have an upstream yet, we use the command line
git push --set-upstream origin HEAD:branch-name
The HEAD: part of this is too unspecific; when checking out a different branch
while the push is still running, then git will set the upstream branch on the
newly checked out branch, not the branch that was being pushed. This might be
considered a bug in git; you might expect that it resolves HEAD at the beginning
of the operation, and uses the result at the end.
But we can easily work around this by explicitly supplying the real branch name
instead of HEAD.
This might seem controversial; in many cases the client code gets longer,
because it needs an extra line for an explicit `return nil`. I still prefer
this, because it makes it clearer which calls can return errors.
This broke with 81b497d186 (#3387). In that PR I claimed that we never want to
ask for force-pushing if the server rejected the update, on the assumption that
this can only happen because the remote tracking branch is not up to date, and
users should just fetch in this case. However, I didn't realize it's even
possible to have a branch whose upstream branch is not stored locally; in this
case we can't tell ahead of time whether a force push is going to be necessary,
so we _have_ to rely on the server response to find out. But we only want to do
that in this specific case, so this is not quite an exact revert of 81b497d186.
To determine whether we need to ask for force pushing, we need to query the push
branch rather than the upstream branch, in case they are not the same.
Lazygit has two ways to decide whether it needs to ask the user to force-push:
1. if it knows ahead of time that the push will fail because the branch has
diverged, by looking at the incoming/outgoing information that it shows as ↑3↓7.
2. by examining the error that comes back when the push has failed.
The second situation should happen only rarely, because lazygit fetches every
minute by default, so the ↑3↓7 information is usually up to date. It might not
be if the user turned off auto-fetch (or increased the auto-fetch interval).
However, in this case it's almost always harmful to prompt the user to
force-push, because we know that the reason for diverging is that something was
pushed to the remote, and we would wipe it out by force-pushing. In such a
situation, the more likely user action is to pull the remote changes and then
push normally again.
So just remove the second prompt, and replace it by a better error message when
we detect that updates were rejected remotely.
A little bit of history archeology reveals that the second prompt was added at a
time where we didn't have the first one yet, so at that time it made sense to
have it; but when the first prompt was added, we should have removed the second.
This adds a bunch of tooltips to keybindings and updates some keybinding descriptions (i.e. labels).
It's in preparation for displaying more keybindings on-screen (in the bottom right of the screen),
and so due in part to laziness it shortens some descriptions so that we don't need to manage both
a short and long description (for on-screen vs in-menu). Nonetheless I've added a ShortDescription
field for when we do want to have both a short and long description.
You'll notice that some keybindings I deemed unworthy of the options view have longer descriptions,
because I could get away with it.
When pulling/pushing/fast-forwarding a branch, show this state in the branches
list for that branch for as long as the operation takes, to make it easier to
see when it's done (without having to stare at the status bar in the lower
left).
This will hopefully help with making these operations feel more predictable, now
that we no longer show a loader panel for them.
The global counter approach is easy to understand but it's brittle and depends on implicit behaviour that is not very discoverable.
With a global counter, if any goroutine accidentally decrements the counter twice, we'll think lazygit is idle when it's actually busy.
Likewise if a goroutine accidentally increments the counter twice we'll think lazygit is busy when it's actually idle.
With the new approach we have a map of tasks where each task can either be busy or not. We create a new task and add it to the map
when we spawn a worker goroutine (among other things) and we remove it once the task is done.
The task can also be paused and continued for situations where we switch back and forth between running a program and asking for user
input.
In order for this to work with `git push` (and other commands that require credentials) we need to obtain the task from gocui when
we create the worker goroutine, and then pass it along to the commands package to pause/continue the task as required. This is
MUCH more discoverable than the old approach which just decremented and incremented the global counter from within the commands package,
but it's at the cost of expanding some function signatures (arguably a good thing).
Likewise, whenever you want to call WithWaitingStatus or WithLoaderPanel the callback will now have access to the task for pausing/
continuing. We only need to actually make use of this functionality in a couple of places so it's a high price to pay, but I don't
know if I want to introduce a WithWaitingStatusTask and WithLoaderPanelTask function (open to suggestions).
We have not been good at consistent casing so far. Now we use 'Sentence case' everywhere. EVERYWHERE.
Also Removing 'Lc' prefix from i18n field names: the 'Lc' stood for lowercase but now that everything
is in 'Sentence case' there's no need for the distinction.
I've got a couple lower case things I've kept: namely, things that show up in parentheses.
