Since the reflog can get very long, this saves some memory but especially some
UI thread lag. In one of my repos I had over 11'000 reflog entries (I guess I
should prune them more regularly...), and rendering them took ~600ms; since this
happens on the UI thread, there was an annoying stall for half a second after
every background fetch, for example.
This fixes a bug in ListContextTrait.FocusLine whereby the view would go blank
when scrolling by page (using ',' or '.') in views that have
renderOnlyVisibleLines set to true but refreshViewportOnChange set to false.
Currently we don't have any such views; the only ones who use
renderOnlyVisibleLines are commits and subcommits, and they also use
refreshViewportOnChange. However, we are going to add one in the next commit,
and eventually it might be a good idea to convert all our list views to that by
default, and get rid of the renderOnlyVisibleLines flag.
Move SetContentLineCount into OverwriteLinesAndClearEverythingElse. Calling it
separately beforehand is not concurrency safe; we need both to happen
when the view's writeMutex is locked.
We have this logic to avoid constantly rerendering the main view when hitting
up-arrow when you are already at the top of the list. That's good, but we do
want to scroll the selection into view if it is outside and you hit up or down,
no matter if it changed.
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 selection down by the number of commits that were reverted (to keep
the same commits selected). However, this only happens after refreshing, which
has rendered the main view with the wrong commit, so we need to render it again
after moving the selection.
There are many other callers of MoveSelection in LocalCommitsController, but all
of them happen before the refresh. Revert is special because it needs to move
the selection after refreshing, e.g. when reverting the only commit of a branch.
Now that we can use 'k' as a menu item binding (this was fixed in #5131), use it
for the "keep" entry in the merge menu. I don't think this will be a problem for
people's muscle memory, given that this menu is not encountered every day; and
it's simply the better keybinding.
This reverts commit b32b55201e0b392c777846de75eae3a2183aada6.
This is not really super important because we are very unlikely to assign a key
such as esc or up/down to a menu item. However, users might do this in a custom
commands menu, and in that case it is important that the builtin keys still
work; or they might remap those builtin commands to other keys, in which case
they might conflict with single-letter keys in normal menus.
The confirmation used to make sense back when the Open MergeTool command was its
own top-level command; however, that command was changed in 703f053a7e to open a
menu instead, and Open MergeTool is now just a submenu entry in that menu, so it
no longer needs a confirmation.
Users have filed issues with crash reports that seem to indicate that the
FileTreeViewModel gets swapped out (by a refresh) while a call to itemsSelected
is in progress, iterating over the previous items. Guard against this by locking
the mutex that we already have for this for the duration of the call.
I don't have a good way of testing whether the fix helps, because the crashes
only occurred very infrequently. Let's just see if the crash reports stop coming
in after we ship this.
Note also that this is only the minimal fix for the crashes that were reported.
Theoretically, the same problem could happen for a key handler itself, but we
never saw reports about that, so we don't bother doing anything about that yet.
Note also that long-term I envision a different solution to this class of
problems (discussed in https://github.com/jesseduffield/lazygit/issues/2974),
that's why I want to avoid locking mutexes more than necessary now.
It is a bit generic, it seems that users sometimes set it for other reasons, and
then they are confused why they don't see anything. Use a more specific name
instead.
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.
This doesn't really solve a pressing problem, because I guess it's unlikely that
users add spaces at the beginning or end of what they type into a prompt; but it
could happen, and in this case we almost always want to strip it. Just adding
this here for completeness while I was working on this code.
The only exception is the input prompt of custom commands, because who knows
what users want to use that input for in their custom command.
Most of our prompts don't (shouldn't) allow empty input, but most callers didn't
check, and would run into cryptic errors when the user pressed enter at an empty
prompt (e.g. when creating a new branch). Now we simply don't allow hitting
enter in this case, and show an error toast instead.
This behavior is opt-out, because there are a few cases where empty input is
supported (e.g. creating a stash).
Previously it was used both for the Confirm handler and the Cancel handler, as
well as for the Confirm handler of confirmation popups (not prompts). There was
no other way to do it given how wrappedConfirmationFunction was shared between
all these; but now there is. The logic is really only needed for the Confirm
handler of prompts.
This doesn't fix anything, it just makes things clearer.
And call this new helper function from both wrappedConfirmationFunction and
wrappedPromptConfirmationFunction; this gives us more flexibility to do
different things in each of those.
Introduce the 'SelectedSubmodule' struct and allow using it as a
placeholder value.
Add a corresponding test.
Update the documentation to include it among the listed placeholder
values.
When pressing '.' (next page) or ',' (previous page), the selection
now stays at the bottom or top of the viewport respectively, instead
of being centered which caused items to scroll off. If the selection is not
already on the last/first line of the view, '.'/',' moves it there without
scrolling.
This implements a special case for page navigation as suggested by
the maintainer in issue #5017, keeping the cursor position consistent
with user expectations for page-based navigation.
Fixes#5017

The existing diff parser incorrectly treated subsequent lines beginning
with "---" as filename headers while processing hunks. This caused
corruption when dashed lines appeared within diffs themselves.
Restrict filename detection to only occur between hunks.
When replacing the naked return with a `return result`, the linter starts to
complain about "return copies lock value: sync/atomic.Int32 contains
sync/atomic.noCopy". I suspect this is also a problem when using a naked return,
and the linter just doesn't catch it in that case. Either way, it's better to
use a pointer to ensure that the atomic is not copied.

This will put whatever git's default merge variant is as the first menu item,
and add a second item which is the opposite (no-ff if the default is ff, and
vice versa).
If users prefer to always have the same option first no matter whether it's
applicable, they can make ff always appear first by setting git's "merge.ff"
config to "true" or "only", or by setting lazygit's "git.merging.args" config to
"--ff" or "--ff-only"; if they want no-ff to appear first, they can do that by
setting git's "merge.ff" config to "false", or by setting lazygit's
"git.merging.args" config to "--no-ff". Which of these they choose depends on
whether they want the config to also apply to other git clients including the
cli, or only to lazygit.
- Squash and FastForwardOnly are mutually exclusive, and instead of asserting
this at runtime, model the API so that they can't be passed together.
- FastForwardOnly is unused, so remove it; however, we are going to need --ff
and --no-ff in the next commit, so add those instead.
- Instead of putting the enum into the MergeOpts struct, replace the struct by
the enum. We can reintroduce the struct when we add more arguments, but for
now it's an unnecessary indirection.
