edit, quick-start rebase, drop, reword, squash, fixup, amend
(including the amend-attribute author operations) and
discard-file-from-commit all run a rebase on a worker. A key pressed
while one is in flight could act on a stale commit or todo — pressing e
to start an interactive rebase, then up+d before it finishes, is the
motivating example. Switch them from WithWaitingStatus to
WithWaitingStatusBlockingInput so input is held and replayed against the
post-operation state, matching the commit-surgery ops that were already
sync.
Left alone: the custom-patch move/delete/pull-into-commit rebases (no
need to block input while building and applying a patch), the
loading-more-commits and patch-building toggle spinners (no rebase to
disrupt), and fetches and other non-surgery operations where blocking
navigation would only get in the way.
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.

The discard handler cancelled the commit-files range selection from its
WithWaitingStatus worker. Bounce it through OnUIThread, keeping it after
the successful CheckMergeOrRebase as before.
discard reads Model().Commits and the selected commit index from its
WithWaitingStatus worker; read them in HandleConfirm instead.
toggleForPatch reads the commit-files ref name from the worker, and its
startPatchBuilder call reads the context's canRebase and diff range from
there too. Capture the ref name and run startPatchBuilder in
HandleConfirm before dispatching; PatchBuilder.Start only assigns
fields, so moving it off the worker changes no timing.
discard still collapses the range selection from the worker; that write
is a separate concern, left for a follow-up.
When loading the files of a commit we passed --no-renames, so a rename
showed up as a separate delete and add rather than a single R entry.
That made it impossible to work with a rename that also modifies the
file: the modifications were spread across a full deletion and a full
addition instead of appearing as the handful of lines that actually
changed. The staging view already shows renames and lets you stage
their hunks, so there was no good reason for the patch builder to
differ; the flag was only there because the commit-file parser couldn't
cope with the rename record format.
Switch the commit-file loader and the per-file diff to --find-renames,
teach the parser about the rename record (a status followed by two
paths), and carry the previous path through the patch builder so the
diff for a rename is loaded with both paths, which is what makes git
emit the rename in the first place.
A whole-file selection keeps the rename in the header, so the rename
moves or is discarded together with the file's contents. A partial
selection instead strips the rename metadata and points the header at
the new path, so applying the patch only changes the contents and
leaves the rename in place; the blob index line is kept so that a 3-way
apply can still fall back to a blob merge.
Discarding a renamed file from a commit now discards both the new and
the old path, so the new file is removed and the old one is restored.
Changing the rename similarity threshold refreshes the commit files
panel too, not just the files panel, so that a rename can turn into a
delete and add or back. It is disabled while building a patch, however,
because the patch builder caches each file's diff by path and would
desync if a rename changed into a delete and add underneath it.
Finally, copying a file's diff from the commit files panel now passes
both paths for a rename, so the copied diff shows the rename instead of
a new-file add.

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.
The redraw of the selection color (using <space>) would be tied to the
spinner drawing. To reproduce, having a high spinner refresh rate and
toggling a file would see a delay equivalent to the time spinner refresh
rate.
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.
Change working tree files and commit files panels to use filtering
(reducing the list) instead of search (highlighting matches). This
matches the behavior of other filterable views.
The text filter matches against the full file path, not just the
filename, which is more useful for navigating large directory trees.
When toggling a directory for a custom patch while a text filter is
active, only the visible filtered files in the directory are affected,
consistent with how staging a directory in the files panel works.

Only mention resetting the patch when there actually is one. This way users have
to read less text in the normal case, and the added note hopefully stands out
more if there is one. Also, separate the note from the previous text by a blank
line.
"Remove" can be confusing when a deleted file is selected; in this cases it
actually "un-removes" it. "Discard" hopefully makes it clearer that we are
talking about the change to a file, and not the file itself.
The code was copied from StagingController in 0496e3af50, and I did add the new
text in that commit, I just forgot to adapt the code to actually use it.
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.
This was added after this PR comment:
https://github.com/jesseduffield/lazygit/pull/3276#discussion_r1469077611

I don't understand what "cancel on the next popup" means; there is no further
popup after this code.
This is very similar to what we are doing for staging or discarding hunks in the
Files panel. Git doesn't allow applying patches with a zero context size (unless
you use the --unidiff-zero option, which is discouraged).
Previously we would render the diff for a directory to the main/secondary pair,
but a diff for a file to the staging/stagingSecondary pair. (And similar for
commit files: main/secondary for directories, but
patchBuilding/patchBuildingSecondary for files.)
I always found this confusing and couldn't really understand why we are doing
this; but now it gets in my way because I want to attach a controller to
main/secondary so that they can be focused. So change it to always use the main
context pair for everything we render from a side panel.
This is useful for copying the entire content of the selected file as it was at
the selected commit.
We only add it to the commit files panel; it is not needed in the files panel,
because there you can simply press "e" to edit the file.
This is very similar to the same menu in the Files panel, except that it works
on whatever diff is currently shown in the main view, including range diffs
either in diffing mode (shift-W), or from a range selection of commits.
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.
We make the name of the GetSelectedRefRangeForDiffFiles very specific on purpose
to make it clear that this is only for switching to diff files, so the
implementations can make assumptions about that (unlike GetSelectedRef, which is
used for different purposes and needs to stay more generic).
In the next commit it will be reused for checking whether we need to reset the
patch; and extracting it makes it easier to extend it for non-sticky diff ranges
later in the branch.
The comments that I'm deleting here explain why we need the bool; however, in
our case that's a theoretical issue. It would only arise if we ever were to pass
a nil context to SetParentContext, which we never do.
