Besides the misleading error about submodules, the command crashes when
it runs before the first files refresh has come in: the file tree
doesn't exist yet at that point, and staging all of a tree that isn't
there dereferences a nil root node. That is easy to hit in a big repo,
where `git status` takes a moment while the panel sits there empty.

The stage-all command acts on the whole file tree, and nothing stops it
from doing that when the tree is empty. It ends up in the branch that
explains why a submodule couldn't be staged, which has nothing to do
with what the user did.

This is usually not a problem (except for the unnecessarily wasted time)
because all worktrees should normally be correctly formatted; but it is
a problem when we bump the formatter version, and some worktrees are
already on the new version and others still on the old.

In v0.58 (see #5134) we changed the refresh behavior to no longer scroll
a selection into view by default if it had been scrolled out of view
using the mouse wheel; the primary reason for that was to avoid a
background fetch or files refresh to yank the selection back into view
while you are looking at something else, which was pretty annoying.
However, that meant we had to fix lots of cases where the selection
didn't become visible after a normal, foreground user action, and add
code to manually scroll it into view again in those cases. This is
error-prone and easy to forget for new features, and to this day we were
still missing some.
So turn it around: by default, the selection is scrolled into view
again, and the few cases where we don't want it (background routines and
the focus-in refresh) opt out.
This does mean that some user actions now scroll into view that didn't
before, and there might be cases where this is unwanted (I can't think
of one, but who knows). If we come across one we can easily fix it by
opting out; this is probably still much better than not scrolling into
view where it's wanted.
Every one of these did by hand what focusing the list now does on its
own: five hand-added scroll requests, and four origin resets that paired
a "select the first item" with a "and show the top of the list".
The scroll that the commits refresh performed when it found the selected
commit at a new index goes too. It is now unconditional for a foreground
refresh, and deliberately absent for a background one: when an agent
commits in another window, we would rather see the new commits arrive
than have the view yank itself back to the commit we had selected.
The one origin reset that stays is the one in ReApplyFilter, which runs
as part of a refresh and so can't rely on the refresh scrolling.

Ever since scrolling the selection into view became opt-in, we have been
fixing the same class of regression by hand, five times so far: a
controller moves the selection somewhere new, doesn't say that it wants
the view to follow, and the selection ends up off screen. The decision
needs facts from two places — whether the selection went somewhere new is
known to the list, whether the scroll position is the caller's to manage
is known to the caller — and asking every caller for both is what keeps
going wrong. The callers that get it wrong are usually not even the ones
that moved the selection: they are pass-throughs like postRefreshUpdate,
which can't know what a refresh did to the selection.
So default to scrolling, and let the two callers that maintain the scroll
position themselves say so.
The one case where scrolling is always wrong is a refresh that no user
action is behind: a background poll, or a reload of state on window
focus, after a subprocess, or after a repo switch. Those must leave the
viewport wherever the user last scrolled it to — that is what made the
scrolling opt-in in the first place. Both are already marked in
RefreshOptions, so the refresh can decide it once, centrally, instead of
each caller judging it.
A user action that ends in a foreground refresh does now yank the view
back to the selection if the user had scrolled away from it. That's a
behaviour change, and there may be actions where it turns out to be
unwelcome; those we can fix individually, and it beats the ones that
don't scroll today.

Since scrolling the selection into view became opt-in, five places have
had to be fixed by hand after the fact, none of them with a test. Cover
them now: making the scrolling automatic has to keep all five working,
and once it does, the hand-added scroll calls can go.
Two of them assert that the selection is visible rather than on an exact
scroll position, because the panel they look at changes height along the
way (filtering mode switches to half screen), or because what matters is
only that the commit we jumped to can be seen.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
This is the other place that manages its own scroll position: while a
drag extends the selection to a line below the viewport, the view stays
put, and the drag autoscroller scrolls it one line at a time for as long
as the pointer stays there. Making the scroll automatic would centre the
selection instead, i.e. jump the view rather than scroll it.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The one behaviour that made scrolling the selection into view opt-in in
the first place — a background refresh must not yank the view back to a
selection the user scrolled away from — has never been covered by a test.
It's about to become the one case that the automatic scrolling has to
suppress, so cover it first.
Getting there needs two things from the test harness: mouse wheel events,
which are the only way to scroll a list panel without moving the
selection, and a way to trigger a background refresh. The periodic
routine that issues it is turned off in tests, and turning it on would
mean waiting for its timer and hoping it fires while we're looking, so
drive the refresh directly instead.

We are about to make list panels scroll their selection into view
automatically. Page up and down are one of the few places that manage
the scroll position themselves, keeping the selection at the edge of the
viewport rather than in its middle, and nothing covers that today.
Asserting on it needs an exact scroll position assertion; only
OriginYAtLeast existed so far.

A lazygit instance that has been open for a while sometimes stops
showing pull requests, and keeps not showing them until you quit and
restart it. The cause is that we resolve the GitHub token once per
process and then keep using that stale answer.
We get the token from go-gh, which reads gh's `hosts.yml` on the first
call and caches it for the lifetime of the process. gh rewrites that
file whenever the active account changes, and keeps the active account's
token either in the file or in the system keyring, depending on the
account. Once the file changes under us, our snapshot no longer
describes reality: either we keep sending a token for an account that is
no longer active, or — if the snapshot was taken while a keyring-backed
account was active — we find no token at all, drop the remote, and show
no pull requests. Nothing is reported to the user, so it looks like PR
fetching is simply broken.
Switching accounts with `gh auth switch` is the easiest way to trigger
this, but it isn't limited to multi-account setups: a single account
hits the same thing whenever its token is rotated, or moved between the
keyring and `hosts.yml` by a fresh `gh auth login`.
So ask gh itself for the token on every refresh, with `gh auth token
--hostname <host>`, which resolves it afresh from whichever of the
environment, the keyring, or the config file currently holds it. Not
passing `--secure-storage` (which go-gh does internally) also means it
stops mattering which of the two the active account uses. go-gh's lookup
stays as a fallback for setups without the gh binary, where it still
picks up `GH_TOKEN` and friends; when gh is present it checks those
variables itself.
To reproduce on master, with two gh accounts, one with its token in the
keyring and one in `hosts.yml`: start lazygit while the keyring-backed
account is active, then run `gh auth switch` to the other one. The pull
request information disappears on the next refresh and doesn't come back
until lazygit is restarted. Running `gh auth token --secure-storage
--hostname github.com` by hand at that point prints `no oauth token
found for github.com`.
go-gh reads gh's config file once per process and answers from that
snapshot for the rest of the process's life. gh rewrites the file
whenever the active account changes, and stores the active account's
token either in it or in the system keyring, depending on the account.
A lazygit that has been running for a while therefore consults a
snapshot that no longer describes reality: it either keeps using a
token for an account that is no longer active, or, when the snapshot
was taken while a keyring-backed account was active, finds no token at
all and silently stops showing pull requests until it is restarted.
Asking gh resolves the token afresh on every refresh, from whichever of
the environment, the keyring or the config file currently holds it.
go-gh's lookup stays behind as a fallback for setups without the gh
binary, where it still picks up GH_TOKEN and friends.

When confirmOnQuit is true, quitting would sometimes hang for three
seconds and then print "cannot kill child process". Concretely, this
happened whenever the Files panel was focused but there were no changed
files (the main view shows "No changed files").
This is a regression in 0.64.0, it worked before.
Fixes#5918.
Quitting with confirmOnQuit set hung for three seconds and printed
"cannot kill child process", but only with a clean working tree. Closing
the confirmation pops the context before running its handler, so the
files panel is re-focused and re-renders the main view, and only then
does the handler return ErrQuit. With no changed files that render is a
string task, whose whole body is one hop to the UI thread — a hop that
is never served, because the handler's ErrQuit has meanwhile brought the
main loop down. The task can't finish, so the ViewBufferManager.Close
that follows waits for it until it times out. (With changed files it's a
command task instead, and every blocking point in one of those selects
on the stop channel, so Close gets through.)
A wait for the UI thread now ends when the loop does. That also covers
the command task's own hops, which are stopped only in between them.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Nothing dequeues user events once MainLoop has returned, so a worker
blocked in OnUIThreadAndWait is blocked for good. The assertion records
that; the next commit makes the wait give up instead.

Right now the function always returns nil, but this will change later in
this branch, so handle errors properly. Without that, the first capture
that assigns env.git would not run, leave env.git nil, and subsequent
code would crash.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Every caller passes an f that unconditionally returns nil, so f's error
return has never carried anything: the value is dead weight, and it
occupies the one channel the wait itself needs to report that it couldn't
run f at all. Drop it, so that the error the wait returns can only ever
mean that.
Work that can fail hands its error back through a captured variable, the
way the background fetch already hands back four values, which keeps the
two outcomes distinguishable at a call site that has both.

If the `conflict-marker-size` git attribute is used to set the marker
size to a non-default value (!= 7), lazygit's handling of conflicted
files was totally broken. Stopping at a commit with conflicts in a
rebase would show the `UU` files for a moment, and then, a few seconds
later, would stage all conflicted files and offer to continue the rebase
(with the conflicts baked into the resulting commits if you confirmed).
Even if you cancelled the continue prompt, it wasn't possible to use
git's conflict panel to resolve the conflicts; it would only show the
regular diff for those files, not its conflicts editor.
Fix this by querying the `conflict-marker-size` git attribute for all
conflicting files and use that to match the conflict markers.
Fixes#4367.
Git only writes the space after a marker when there is a label to write
after it, and the label can be empty: `git checkout -m` with the diff3
conflict style, for instance, has no name for the common ancestor, so it
writes a bare "|||||||" line.
Ask git for the attribute of every conflicted file whenever we load the
file status, so that we recognize the markers it actually wrote. Files
that are set up this way are precisely the ones whose regular content
tends to contain marker-looking lines, so matching a run of at least
seven characters instead is not an option: we'd take the file's own
content for markers and then never consider its conflicts resolved.
One `git check-attr` call covers all conflicted files at once; asking per
file would take seconds when hundreds of files are conflicted, and it
would hurt worst on Windows, where spawning a process is expensive.
Because the lookup rides along with the file status, it costs nothing
when there are no conflicts, and editing .gitattributes during a merge
takes effect on the next refresh.
When a file's conflict markers aren't seven characters long we don't
recognize them at all. Two things go wrong: we consider the file's
conflicts resolved, so we stage it and offer to continue the merge a
moment after stopping at it; and pressing enter on it shows its diff
instead of the merge conflicts view, leaving no way to resolve it in
lazygit.
Git doesn't always write conflict markers of seven characters: the
conflict-marker-size gitattribute overrides that per file, and it is set
for good reasons — for file types whose regular content tends to contain
marker-looking lines, such as documentation about merging, or test
scripts. We hard-code seven characters everywhere we look for markers,
so none of that works.
Prepare for honoring the attribute by threading the marker size through
everything that recognizes a marker, carried on the file model. Nothing
fills it in yet, so we still use git's default size of seven everywhere,
and matching is unchanged: a marker consists of exactly that many marker
characters, and all but the "=======" one are followed by a space and a
label.
This fixes a regression in 0.64.0: before that version, creating or
popping a stash would happen synchronously on the UI thread (including
the refresh), blocking the UI until everything changed, including the
panel focus. Blocking the UI was not nice of course, but at least the UI
update was clean. With 0.64.0 this changed to a background refresh, so
that the update to the two panels and the focus change all happened out
of sync, which looks rather ugly. Fix this by using Refresh's mechanism
to batch UI updates, and switch the panel focus in the Refresh's Then so
that it updates at the same time.
While we're at it, use a waiting status spinner for these operations;
they are usually fast when only few files are involved, but when
stashing a large number of files in a larger repo it can be noticeable,
and it looks ugly if the confirmation prompt stays on the screen while
it is running.
Creating and applying a stash both touch every changed file, so in a
large repo they can take long enough to be noticeable — and running them
on the UI thread meant the confirmation popup stayed on screen, frozen,
for the whole operation. Run them on a worker instead, with a spinner,
and keep blocking input for their duration so that the type-ahead
guarantee the refresh used to provide still holds.
Dropping stays on the UI thread: it only rewrites the stash reflog, so
it's fast no matter how big the stashes are.

Collapsing the range before kicking off the refresh paints the new
selection against the list as it was before the drop, so for a frame the
entries that were just dropped are still on screen (and, with
gui.shrinkSidePanelsToContent, the panel is still at its old size).
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Pushing the files context right after kicking off the refresh moves the
focus (and, with gui.shrinkSidePanelsToContent, resizes the panels) a
frame before the refreshed stash and files lists arrive. Doing it from
Then puts it in the same frame as the data it belongs to.

Stashing and popping change both the stash list and the files list.
With each scope updating the UI as soon as its own refresh is done, the
two panels visibly change at different times; with
gui.shrinkSidePanelsToContent that also means their sizes change at
different times than their contents.

Lazygit assumes a repo can be found again from its working directory: it
chdirs there and lets git rediscover the git dir from `<worktree>/.git`.
That holds for an ordinary repo and breaks for every setup where the git
dir lives somewhere else, which is where these bugs come from. Opening
such a repo worked at all only when `--git-dir` happened to leave
`GIT_DIR` in the environment for every command to inherit — which is
also why entering a submodule, which has to clear it, broke the way back
out.
Three reported problems:
- **`core.worktree` (#5895).** A repo whose work tree is elsewhere
panicked on startup with `fatal: not a git repository`: we chdir'd into
a work tree with no `.git` in it and every command after that was lost.
We now work out at startup whether git can find the repo from its work
tree, and when it can't we put `GIT_DIR`/`GIT_WORK_TREE` on every
command the repo's command builder produces — as well as in the process
environment, for subprocesses that don't come through the builder.
Nothing is set for the repos git can find on its own, which is nearly
all of them.
- **Escaping a submodule of a dotfile repo (#1118).** The repo-path
stack we push the superproject onto only held its path, and for a repo
opened with `--git-dir`/`--work-tree` the path leads nowhere. Escaping
failed with `not a git repository`, or, if some unrelated repo happened
to lie above the work tree, quietly switched to that one instead. The
stack now carries the environment as well, taken from the repo paths
rather than from the process env, so it also covers a repo whose
location lazygit worked out itself.
- **Opening a directory that holds a bare repo (#5469, #5681).** `git
rev-parse --show-toplevel` is fatal when there's no work tree, so we
never got an answer at all for a bare repo: `IsBareRepo()` could never
come out true, and lazygit either died with a stack trace or decided we
weren't in a repository. We now ask again without `--show-toplevel` when
the first query fails, and the existing "open most recent repo?" prompt
does its job.
Some related things that turned up on the way:
- **A submodule no longer looks like a linked worktree.** `git worktree
list` reports the main worktree as the common git dir with a trailing
`/.git` removed, which is not the working tree when the git dir doesn't
live inside it. Comparing that against the working tree path matched
nothing, so inside a submodule the status bar claimed we were in a
linked worktree named after the submodule, the worktrees panel listed it
as not current, and its branch got a "checked out elsewhere" marker.
Worktrees are now identified by their git dir, which names them
unambiguously.
- **Commands aimed at another repo no longer resolve against ours.**
With `GIT_DIR` set, `git -C mysub log -1` reports the *superproject's*
commit, silently. So opening lazygit with `--git-dir`/`--work-tree`
quietly broke resolving submodule conflicts, stashing and resetting a
submodule, and detaching another worktree.
- **Starting lazygit in a repo's `.git` dir opens the repo.** It used to
tell you that you were in a bare repo, which you weren't — the work tree
was one directory up. git's own convention is that a git dir called
`.git` belongs to the directory holding it, so we look there. (A linked
worktree's or a submodule's git dir isn't called `.git`, and nothing we
look at says where their work tree is, so those still get the prompt.)
- **`RepoPath()`** is documented to be the work tree when we're in the
main worktree, but was derived from the git dir's location, which is
only the same thing when the git dir is inside the work tree. This fixes
the repo name shown in the status panel for split setups.
Fixes#1118Fixes#5469Fixes#5681Fixes#5736Fixes#5895
Running lazygit in a .git dir got you told you were in a bare repo,
which you weren't: the worktree was sitting right there, one directory
up. git's own convention is that a git dir called .git belongs to the
directory holding it — that's how `git worktree list` names the main
worktree — so ask that directory, and if it is a worktree, open the repo
we were really being asked about.
The git dirs that aren't called .git keep the answer they had. A linked
worktree's and a submodule's do have a worktree, but nothing we look at
says where, so we would be guessing; a bare repo's has none to find.

Entering a submodule clears GIT_DIR and GIT_WORK_TREE, as it must: they
say where the superproject is. But the stack we push the superproject
onto so that escape brings us back only held its path, and for a repo
opened with --git-dir/--work-tree the path leads nowhere — git can't
find a repo there. Escaping out of a submodule of a dotfile repo failed
with "not a git repository", or, if some unrelated repo happened to lie
above the work tree, quietly switched to that one instead.
Push the environment onto the stack along with the path, taken from the
repo paths rather than from the process env, so that it also covers a
repo we worked the location out for ourselves.

git finds a repo by looking for a .git in the directory a command runs
in. Lazygit runs its commands in the work tree, so that normally works —
but not when the git dir lives somewhere else entirely, which is what
core.worktree and --work-tree are for. Lazygit chdir'd into such a work
tree and then ran commands that couldn't see any repo from there, so
opening a repo with core.worktree set panicked on startup. It only
worked with --git-dir because that leaves GIT_DIR in the environment for
every command to inherit.
Work out at startup whether git can find the repo from its work tree,
and when it can't, put GIT_DIR and GIT_WORK_TREE on every command the
repo's builder produces. As with the working directory the builder pins
(527124d0e0), these also go into the process env — subprocesses don't
come through the builder — but the commands don't read them from there,
because the process env belongs to whichever repo we have switched to
since.
Working out whether git can find the repo means asking git, rather than
reading the .git file, whose contents can spell the same directory
differently than git does. The extra query is skipped for a repo whose
git dir is simply its .git directory, which is nearly all of them.

GIT_DIR and GIT_WORK_TREE tell git where our repo is, and every command
we run inherits them — including the ones we point at a submodule or
another worktree. git resolves those against our repo instead, and says
nothing about it: with GIT_DIR set, `git -C mysub log -1` reports the
superproject's commit. So opening lazygit with --git-dir/--work-tree
quietly broke resolving submodule conflicts, stashing and resetting a
submodule, and detaching another worktree; the worktree list came back
claiming every worktree shared our git dir.
Drop the two variables from the commands that address another repo.
