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.
When opening lazygit with `lazygit log` the worktrees view was appearing in front of the files view.
This is because it had higher precedence than the files view in the ordered view mapping, and
that was because it originally was in the branches window so it was further down the list.
The reason this didn't cause issues on typical startup is that the files context is activated at the
start so it is brought to the front.
I've been thinking about this for a while: I think it looks really cool if nuking your working tree
actually results in a nuke animation.
So I've added an opt-out config for it
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 are in the outsideFilterModeBindings section here; all of these handlers are
wrapped in a OutsideFilterMode guard in a loop below. No need to add one
manually here.
It's tricky to get this right for reflog commits wrt what's the current branch
for each one; so just disable it entirely here, it's probably not something
anybody needs here.
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.
The model will be used for logic, so the full hash is needed there; a shortened
hash of 8 characters might be too short to be unique in very large repos. If
some view wants to display a shortened hash, it should truncate it at
presentation time.
- check out a non-main branch before we start
- add authors to expected commits so that we can see whether the commits show an
asterisk
- explicitly check what the top line displays after bisecting has started
This shows that the detached head shows an asterisk, which we don't want. We'll
fix that in the next commit.
This test not only tests the correct handling and display of the updateRef
command, but also the visualization of branch heads in the commits panel. Since
we are about to change the behavior here, extend the test so that a master
commit is added (we don't want this to be visualized as a branch head), and then
a stack of two non-main branches. At the end of this branch we only want to
visualize the head commit of the first.
Update-ref commands have an empty sha, and strings.HasPrefix returns true when
called with an empty second argument, so whenever an update-ref command is
present in a rebase, all commits from there on down were drawn with a green sha.
From the go 1.19 release notes:
Command and LookPath no longer allow results from a PATH search to be found relative to the current directory. This removes a common source of security problems but may also break existing programs that depend on using, say, exec.Command("prog") to run a binary named prog (or, on Windows, prog.exe) in the current directory. See the os/exec package documentation for information about how best to update such programs.
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
Afero is a package that lets you mock out a filesystem with an in-memory filesystem.
It allows us to easily create the files required for a given test without worrying about
a cleanup step or different tests tripping on eachother when run in parallel.
Later on I'll standardise on using afero over the vanilla os package
When switching worktrees (which we can now do via the branch view) we re-layout the windows and their views.
We had the worktree view ahead of the file view based on the Flatten() method in context.go, because it used
to be associated with the branches panel.
We want to be using forward slashes everywhere internally, so if we get a path from windows
we should immediately convert it to use forward slashes.
I'm leaving out the recent repos list because that would require a migration
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.
This fixes pkg/integration/tests/worktree/rebase.go which was failing on old git versions due to a difference in
order of branches that don't have recency values
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
