Save has been deprecated for a while, push is the recommended way to save a
stash. Push has been available since 2.13, so we can use it without problems.
I've simplifiied the code because it was too complex for the current requirements, and this fixed the misc/initial_open
test which was occasionally failing due to a race condition around busy tasks
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 had a race condition due to refreshing branches in two different places, one which refreshed reflog commits
beforehand. The race condition meant that upon load we wouldn't see recency values (provided by the reflog commits)
against the branches
Turns out we're just running our refresh functions one after the other which isn't ideal but we can fix that separately.
As it stands this wait group isn't doing anything.
I don't know if this is a hack or not: we run a git command and increment the pending action
count to 1 but at some point the command requests a username or password, so we need to prompt
the user to enter that. At that point we don't want to say that there is a pending action,
so we decrement the action count before prompting the user and then re-increment it again afterward.
Given that we panic when the counter goes below zero, it's important that it's not zero
when we run the git command (should be impossible anyway).
I toyed with a different approach using channels and a long-running goroutine that
handles all commands that request credentials but it feels over-engineered compared to this
commit's approach.
The remote branches controller was using its own escape method meaning it didn't go through the flow of cancelling
an active filter. It's now using the same approach as the sub-commits and commit-files contexts: defining a parent
context to return to upon hittin escape.
Given that we now persist search/filter states even after a side context loses focus, we need to make it really
clear to the user that the context is currently being searched/filtered
This is a pickle: initially I wanted it so that a filter would cancel automatically if the current context lost focus.
But there are situations where you want to retain the focus, e.g. when a popup appears, or when you view the commits
of a branch. The issue is that when you view the commits of a branch, the branches context is removed from the context
stack. Even if this were not the case, you could imagine going branches -> sub-commits -> files -> sub-commits, where
in that case branches would definitely be off the stack upon navigating to the files context.
So because I'm too lazy to find a proper solution to this problem, I'm just making it so that filters in side contexts
are retained unless explicitly cancelled.
There's another edge case this commit handles which is that if I'm in the sub-commits context via the branches context
and start a search, then navigate to the reflog context and hit enter to get to the sub-commits context again, I need
to cancel the search before I switch. Likewise with the commit files context.
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.
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.
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.
The root commit is special in that it has no parents. So we need to add a pipe that's headed for a commit
that doesn't actually exist i.e. the mythical empty tree commit. We're using the actual hash of that
pseudo-commit, but it's not being read anywhere.
The menuFromCommand option is a little complicated, so I'm adding an easy way to just use the command output directly,
where each line becomes a suggestion, as-is.
Now that we support suggestions in the input prompt, there's less of a need for menuFromCommand, but it probably still
serves some purpose.
In future I want to support this filter/valueFormat/labelFormat thing for suggestions too. I would like to think a little more
about the interface though: is using a regex like we currently do really the simplest approach?
