The existing git log logic fetched the first 300 commits of a repo and
displayed them in the local and sub-commit views. Once a user selected a
commit beyond a threshold of 200 commits the whole repository was
loaded. This is problematic with large repos e.g. the linux kernel with
currently ~138k commits as lazygit slows down substantially with such a
large number of commits in memory.
This commit replaces the current all or only the first 300 commits logic
with an incremental fetching approach:
1. The first 400 commits of repo are loaded by default.
2. If the user selects a commit beyond a threshold (current limit-100)
the git log limit is increased by 400 if there are more commits
available. If there are more commits available is currently checked
by comparing the previous log limit with the real commit count in the
model, if the commit count is less then the limit it is assumed that
we reached the end of the commit log. Ideally it would be better to
call `git rev-list --count xyz` in the right places and compare with
this result, but this requires more changes.
Adding a "paginated implementation" by utilizing `git log --skip=x
--max-count=y` and appending commits to the model instead of replacing
the whole collection would be nice, but this requires deeper changes to
keep everything consistent.

Checking out a remote branch that has no local counterpart creates the
local branch, refreshes, and then checks it out. The refresh exists so
that CheckoutRef finds the new branch in the model and attaches an inline
status to the branch item instead of showing a global waiting status. But
since UI-thread refreshes stopped blocking, the checkout started before
the refreshed branches had landed in the model, so the lookup failed and
we always got the waiting status. Run the checkout from the refresh's
Then, which is queued behind the model update.

With sync vs async now derived from the calling thread, the Mode field
and its SYNC/ASYNC constants no longer carry any information: Refresh is
always async, RefreshFromWorker always sync. Drop the field, the type,
and the Mode argument at every call site, and reduce the debug log's
mode name to a plain sync/async derived from calledFromWorker.

Creating a branch checks it out, and checking out a distant ref (a tag
or a commit far from HEAD) can take a noticeable while. NewBranch ran
that synchronously in the prompt's confirm handler, on the UI thread, so
the UI froze — no spinner, no repaint — until it finished.
Move the branch creation (and the autostash path) onto a worker with a
waiting status, mirroring CheckoutRef, and refresh from the worker so
the UI thread stays live and the spinner keeps animating.
Push the branches context from the refresh's Then rather than up front:
the refresh already batches its UI updates, so switching panels there
lands the switch in the same frame as the refreshed branch list instead
of flashing the pre-refresh list while the checkout is still running.

BLOCK_UI ran the whole refresh on the UI thread and parked it in a
wg.Wait for the duration, so the UI (and its spinner) froze while the
git work ran. Blocking the UI was never the point — the point was to
apply all the scopes' updates in one frame instead of a per-scope
cascade — and if we genuinely wanted to block input it should span the
whole operation, not just its refresh, which needs a gocui-level
mechanism we don't have.
So drop the mode and add a BatchUIUpdates option that achieves the
"one frame" effect without blocking: each scope's UI-thread bounce is
collected into a shared refreshBounceBatch during the refresh, and once
every scope has finished they're all applied inside a single OnUIThread
task. gocui drains every queued event before it redraws, so one task
means one repaint. The refresh itself now runs SYNC — on a worker when
issued from one (checkout, move-to-new-branch, the rebase-edit result
handling), so the UI thread stays live and the spinner keeps animating.
The batch needs a mutex because the scopes add concurrently from their
worker goroutines, and a closed flag so that any bounces enqueued after
the flush starts — the nested ones a flushed bounce produces in turn,
e.g. scrolling the selection into view — are dispatched immediately as
ordinary follow-ups rather than collected into a batch that nothing
will drain.

ResetToRef ran on a worker and wrote the local-commits and reflog
selection directly (SetSelection(0) on both) before its refresh, racing
the UI thread. Fold those into the refresh's selection intents:
SelectHeadCommit for the commits (after a reset HEAD is the top commit,
and mid-interactive-rebase it correctly picks the real head over the
first todo entry) and SelectTopReflogCommit for the reflog. The
now-atomic SetLimitCommits stays where it is.
The two move helpers run inside the WithWaitingStatus worker that
withNewBranchNamePrompt dispatches to, but read Model().Files/Submodules
(to decide whether to auto-stash) and Model().Commits (the unpushed
commits to cherry-pick off the base branch) from there, racing the UI
thread's model writes. Compute mustStash — needed by both paths — at the
top, and the unpushed commits in the off-of-main menu item, on the UI
thread, and pass them into the helpers.
A commits refresh does its git work on a worker and then reads the model,
the contexts, and the modes for that work directly from there:
LocalCommits.GetSelectionRangeAndMode/GetLimitCommits/GetShowWholeGitGraph,
Model.Commits/MainBranches/HashPool, the filtering path/author. Those are
owned by the UI thread, which is concurrently running the cursor and render
code, so the reads race it — the dominant, confirmed source of the
commits-scope flakes (the startup ClampSelection vs GetSelectionRangeAndMode
race, for one).
Gather them into an immutable capturedCommitState on the UI thread, before
the git work is dispatched, and have refreshCommitsWithLimit compute from
that snapshot. UI-thread callers capture inline; worker callers can't (a
SYNC/BLOCK_UI refresh parks the UI thread at wg.Wait, so hopping from a
scope sub-worker would deadlock), so the capture is lifted out of the scope
worker into the refresh orchestration, and worker callers announce
themselves with a new RefreshFromWorker entry point that hops the capture to
the UI thread and blocks for it (OnUIThreadAndWait). BLOCK_UI runs the whole
refresh on the UI thread regardless of the caller, so it captures inline
too.
Every refresh issued from a worker that reaches the commits (or branches,
which pulls in commits) scope is converted: the fast-forward, branch/tag
delete, worktree remove/detach, push, reword-via-rebase, author edits,
custom-command, hard-reset-with-autostash, reset-to-ref, fetch-and-checkout,
gpg-stream, post-fetch, and external-change-poller refreshes, plus the
branch checkout and move-commits-to-new-branch refreshes.

Operations that check something out (checkout, create branch, move
commits to a new branch, fetch-and-checkout) selected the newly
checked-out branch by calling SelectFirstBranchAndFirstCommit() before
the refresh and passing KeepBranchSelectionIndex so the refresh wouldn't
override it. That set the selection directly, usually from a worker
goroutine (WithWaitingStatus/WithInlineStatus). Now that the refresh's
own selection write is bounced onto the UI thread, the two writes could
land in either order, and under load the refresh's "restore the
previously-selected branch" write would win — leaving the old branch
selected instead of the new one (flaky
move_commits_to_new_branch_from_base_branch).
Replace it with declarative selection intents applied inside the
refresh's own bounce, so the selection is set on the UI thread and
atomically with the list write (no off-thread write, and no BLOCK_UI
needed to avoid a flicker):
- BranchSelection: SelectCheckedOutBranch selects the checked-out branch
(top of the list). The default, KeepBranchSelectionByName, restores
the previously-selected branch by name as before. This replaces the
KeepBranchSelectionIndex bool.
- CommitSelection: SelectHeadCommit (already existed) for the commit.
- SelectTopReflogCommit selects the top reflog entry, since a checkout
adds a new entry there (reflog/checkout relies on this).
SelectFirstBranchAndFirstCommit is gone. The previously-selected branch
is now read at the top of the branches bounce, before the list is
overwritten, so that read moves onto the UI thread too.
fetchAndCheckout's refresh changes from ASYNC to SYNC so its
post-refresh focus switch can run in Then on the UI thread; SYNC keeps
the inline fetch spinner spinning (only BLOCK_UI would freeze it).

Resetting to a commit/branch/tag from the reset menu ran inline on the UI
thread with no spinner; a hard reset to a distant commit can take a while
and blocks the UI meanwhile. Run it on a worker with a waiting status. The
undo/redo callers of ResetToRef already wrap it this way.

With the recently added external change detection, it happens more often
now that we refresh the commits list because an agent made a commit in
the background. In this case, if we keep the selection index the same,
it now points at a different commit, making the main view show a
different commit too, which is confusing and annoying. To fix this,
track the selected commit and range anchor by hash before reloading,
then restore those rows if both hashes still exist. This also allows us
to get rid of some bespoke code that did this for the specific cases of
reverting a commit or cherry-picking commits, because those are now
handled by the generic mechanism.
This is a pure refactor in preparation for letting users configure multiple
alternate bindings for a single command. Every Binding still has exactly one
key, so nothing changes visibly: the cheatsheet, the on-screen options bar,
and the keybindings menu all render identically.
When a Binding ends up with multiple keys, the on-screen options bar will
show only the first (to avoid clutter); the cheatsheet will show all of them (in
a later commit). For now both paths take Key[0].
MenuItem.Key is changed in the same way, it also has a slice of keys now.
In this commit we keep the name `Key` in Binding, KeybindingOpts and MenuItem,
instead of renaming them to `Keys` right away, in order to keep the diff a bit
more readable. We'll do the rename separately in the next commit.
Constructing a menu item key from a literal character requires
gocui.NewKeyRune('r'), which is a bit noisy. Add a private menuKey helper in
both the controllers and helpers packages so the common case in either reads as
menuKey('r'). Duplicating the one-liner is cheaper than a cross-package import
dependency and avoids forcing every controller file to qualify the call.
The reason for doing this now is that we are going to change MenuItem.Key to a
slice of keys later in the branch, which means we'd have to add `[]gocui.Key{`
at each call site, making them even more noisy. With the menuKey helper we can
just change its signature and leave all clients unchanged.
This bundles the keyName and a rune, so that we don't have to pass these around
separately everywhere. This should make it easier to swap out the rune for a
string when we upgrade to tcell v3.
I copied all files except dot files (.github and .gitignore), the _examples
folder, and go.mod/go.sum.
At some point we may want to copy the files back to the gocui repo when other
clients (e.g. lazydocker) want to use the newer versions of them.
For esthetic reasons, checking out a branch (or other ref) blocks the UI until
the refresh is done, so it's important that the refresh doesn't do unnecessary
work. Refreshing pull requests is unnecessary (but costly, when waiting for it)
when a branch is checked out that already existed locally. However, it is
required when checking out a remote branch for the first time, so that the PR
icon appears immediately when there is one.
It is possible to scroll the selection out of view using the mouse wheel; after
doing this, it would sometimes scroll into view by itself again, for example
when a background fetch occurred. In the files panel this would even happen
every 10s with every regular files refresh.
Fix this by adding a scrollIntoView parameter to HandleFocus, which is false by
default, and is only set to true from controllers that change the selection.
We want to do this whenever we switch branches; it wasn't done consistently
though. There are many different ways to switch branches, and only some of these
would reset the selection of all three panels (branches, commits, and reflog).
We move the code to push the branches context into CheckoutRef, this way it
works consistently no matter where we call it from. Previously, checking out
remote branches or tags would switch to the branches view, but checking out a
commit did not.
Note that it now also takes effect for undoing or redoing a checkout, which may
be a bit questionable; but I still think it makes sense for this, too.
Stashing doesn't affect submodules, so if you have a working copy that has
out-of-date submodules but no other changes, and then you revert or paste a
commit (or invoke one of the many other lazygit commands that auto-stash, e.g.
undo), lazygit would previously try to stash changes (which did nothing, but
also didn't return an error), perform the operation, and then pop the stash
again. If no stashes existed before, then this would only cause a confusing
error popup ("error: refs/stash@{0} is not a valid reference"), but if there
were stashes, this would try to pop the newest one of these, which is very
undesirable and confusing.
Previously, the feedback you got when pressing "-" was just a "Checking out..."
status in the bottom line. This was both easy to miss if you are used to looking
for an inline status in the branches panel, and it didn't provide information
about which branch was being checked out, which can be annoying in very large
repos where checking out takes a while, and you only see at the end if you are
now on the right branch.
Improve this by trying to figure out which branch was the previously checked out
one, and then checking it out normally so that you get an inline status next to
it (as if you had pressed space on it). There are cases where this fails, e.g.
when the previously checked out ref was a detached head, in which case we fall
back to the previous behavior.
For the case of creating a new branch by moving commits to it, we were using the
current (old) branch name in the stash name; change this to use the new name
instead.
Refresh is one of those functions that shouldn't require error handling (similar
to triggering a redraw of the UI, see
https://github.com/jesseduffield/lazygit/issues/3887).
As far as I see, the only reason why Refresh can currently return an error is
that the Then function returns one. The actual refresh errors, e.g. from the git
calls that are made to fetch data, are already logged and swallowed. Most of the
Then functions do only UI stuff such as selecting a list item, and always return
nil; there's only one that can return an error (updating the rebase todo file in
LocalCommitsController.startInteractiveRebaseWithEdit); it's not a critical
error if this fails, it is only used for setting rebase todo items to "edit"
when you start an interactive rebase by pressing 'e' on a range selection of
commits. We simply log this error instead of returning it.
I took the set of enabled checks from revive's recommended configuration [1],
and removed some that I didn't like. There might be other useful checks in
revive that we might want to enable, but this is a nice improvement already.
The bulk of the changes here are removing unnecessary else statements after
returns, but there are a few others too.

This makes it possible to use date and time in initial values like this:
```yaml
initialValue: 'ruudk/{{ runCommand "date +\"%Y/%-m\"" }}/'
```
I want to use this to configure my BranchPrefix like this:
```yaml
git:
branchPrefix: 'ruudk/{{ runCommand "date +\"%Y/%-m\"" }}/'
```
I can only guess here: maybe they were added to more clearly document the public
interface of the classes? If so, I don't think that works. Developers who are
not familiar with the convention will just add a new public method to the class
without updating the interface.
Apparently this was an attempt at working around go's lack of default arguments,
but it's very unidiomatic and a bit confusing. Make it a normal parameter
instead, so all clients have to pass it explicitly.
Jesse's comment from https://github.com/jesseduffield/lazygit/issues/4237:
We recently added a new option to check out a commit's branch from within the
commits, reflog, and sub-commits panels:
https://github.com/user-attachments/assets/0a5cf3f2-6803-4709-ae5a-e4addc061012
After using it for some time, I find it annoying that the default option has
changed. I rarely find myself wanting to check out a branch from the commits
panel, and it's rarer still to want to check out a branch from the reflog and
sub-commits panel. Although there may be use cases for this, it is jarring that
something you can always do (checkout the commit) is harder to do than something
that you can sometimes do (checkout the branch).
We've also had a user complain (see
https://github.com/jesseduffield/lazygit/pull/4117) about their muscle-memory
being broken by the recent change, and I have also fallen victim to this. I
don't think that the new branch checkout option is sufficiently useful to
dislodge the existing keybinding, so let's swap them.
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.
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.
