A task's read loop processes one LinesToRead request at a time. The initial
request has a large line count and no Then callback; if the content is shorter
than that, the loop hits EOF on the initial request and breaks out, abandoning
any further requests still sitting in the readLines channel. So a ReadToEnd
call that races a still-loading-but-shorter-than-its-initial-read view has its
Then silently dropped: it isn't fired immediately (the channel was non-nil at
call time) and it's never dequeued.
On EOF, drain the queued requests and fire their Then callbacks before
breaking out, since reaching EOF trivially satisfies any "read more" request.

The layout scrolls a view up if its origin is past the bottom of its
content, to avoid showing blank space (e.g. after a resize). But it measures
content height by the lines loaded so far, and command/pty tasks load
asynchronously. So when a view is re-rendered while scrolled down, the layout
would yank it to the top because only a fraction of the content has been read
yet, then leave it there once loading finished.
Track whether a command task is actively reading (set synchronously when the
task is created, so a layout pass in between sees it; cleared at EOF, but not
when stopped, since that means a newer task is taking over) and skip the
scroll-up clamp for such views. onEndOfInput already re-clamps once loading
completes.

HyperLinkInLine read v.lines/v.viewLines without holding writeMutex, so it
could race a concurrent re-render rebuilding the buffer. It also indexed
v.lines by viewLines[y].linesY after only checking y against len(viewLines);
since refreshViewLinesIfNeeded overwrites viewLines in place without
truncating, the tail can hold stale entries pointing past a shrunk v.lines,
giving an out-of-range panic while a shorter diff is still loading.
Take writeMutex (as the sibling view methods do) and bounds-check linesY
against len(v.lines), returning "no link" rather than panicking.

Instead of a user config that always shows a selection on focus, the
focused main view starts without a selection (matching master). Pressing
<space> shows a selection in the middle of the view (no scrolling);
pressing <esc> hides it again before falling through to exiting the view.
This was already possible, but only when a file was selected, and it woudln't
always land on the right line when a pager was used. Now it's also possible to
do this for directories, and it jumps to the right line.
At the moment this is a hack that relies on delta's hyperlinks, so it only works
on lines that have hyperlinks (added and context).
The implementation is very hacky for other reasons too (e.g. the addition of the
weirdly named ClickedViewRealLineIdx to OnFocusOpts).
Re-rendering a diff into a main view is asynchronous and lazy: the read
loop fills the view a screenful at a time and refreshes as it goes. When
debugging scroll-restore and flicker behaviour, the individual frames go by
too fast to see. Setting LAZYGIT_SLOW_RENDER=<milliseconds> sleeps that long
after each line is written, stretching the load out so the frames become
visible. It has no effect when unset, so it's safe to leave in.

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.

git makes `rev-parse --show-toplevel` fatal when there's no work tree,
so asking for it together with everything else meant we never got an
answer at all for a bare repo: GetRepoPaths returned an error, nobody
ever saw IsBareRepo() == true, and lazygit either died with a stack
trace or decided we weren't in a repository. That's what you got for
opening it in a directory holding a bare repo and a .git file pointing
at it, which is a normal way to keep a repo and its worktrees together.
Ask again without --show-toplevel when the first query fails: the other
queries work fine without a work tree, so if they now succeed we know
we're in a bare repo, and the existing prompt offering to open a recent
repo does its job. If they fail too we're not in a repo at all, and the
first error already says so.
--is-bare-repository is gone from the query: a work tree implies
core.bare is false, so it could only ever come back false there, and
what matters to us is whether there is a work tree to show, which is
what we now go by.

RepoPath() is meant to be the same as WorktreePath() when we're in the
main worktree, but we derived it from the git dir's location instead.
That is only the same thing when the git dir lives inside the work tree.
With core.worktree, --work-tree, or a .git file pointing at a repo dir
that isn't called .git, it lands on a directory that isn't a worktree at
all, and the repo name we show follows it there.
A worktree that has the repo's common git dir to itself is the main
worktree, so use its path. That subsumes the submodule case, whose git
dir lives under the superproject's .git/modules but is still the
submodule's own common dir; --show-superproject-working-tree is now only
needed for a linked worktree of a submodule.
The existing bare repo test asserted a git output that can't occur (a
work tree and --is-bare-repository=true at once), but the rest of it is
the shape of a repo opened with --git-dir/--work-tree, where the new
repo path is the correct one.

When the work tree lives somewhere else entirely — set up with
core.worktree or --work-tree — we're still in the main worktree, so
RepoPath() should be the work tree, as its own doc comment says. Instead
we derive it from the git dir's location, which lands somewhere that
isn't a worktree at all, and the repo name follows it.
The ACTUAL lines are indented as they will be once the EXPECTED ones
replace them, rather than as gofumpt wants them while the comment
markers are still splitting the struct's alignment. That leaves this one
file not gofumpt-clean until the next commit, in exchange for a diff
there that shows only the lines that actually change.

`git worktree list` reports the main worktree as the common git dir with
a trailing "/.git" removed, which equals the working tree only when the
git dir sits inside it. In a submodule, a bare repo, or a repo using
core.worktree it doesn't, so comparing the reported path against the
working tree path matches nothing: no worktree is recognized as current
or as main. Most visibly, inside a submodule lazygit claimed we were in
a linked worktree named after the submodule, and offered to remove that
"worktree".
Comparing git dirs identifies a worktree unambiguously, so use that.
A worktree whose directory is gone has no git dir to compare, and there
we still have nothing better than its path.
The submodule tests were asserting the linked-worktree suffix in the
status view; it is gone now, and the repo name still says which
submodule we're in.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
A submodule's git dir doesn't live inside its working tree, and `git
worktree list` reports it by its git dir. Lazygit compares that against
the working tree path, so it recognizes neither the current nor the main
worktree, and the UI ends up claiming we're in a linked worktree.

### PR Description
Refresh the Nix flake inputs - see #5882.
Direct input revisions:
- `flake-parts`: `758cf7296b` → `427bf4bd94`
- `nixpkgs`: `c9b6fb7985` → `e72e4f2994`
- `treefmt-nix`: `5eda4ee812` → `d1187f8bc7`
- `systems`: unchanged at `da67096a3b`
- `flake-compat`: unchanged at `ff81ac966b`; its immutable URL metadata
was normalized by the lock refresh
The refresh also updates the transitive `nixpkgs-lib` and
`treefmt-nix/nixpkgs` inputs.
The newer nixpkgs revision deprecates `pkgs.nixfmt-rfc-style` because it
now aliases `pkgs.nixfmt`. Uses the current attribute directly,
preserving
formatter behavior and removing the two evaluation warnings.
### Testing
- `nix flake check`
- `nix develop --ignore-environment -c just format` with a writable
`GOCACHE`
- `nix develop --ignore-environment -c just build` with a writable
`GOCACHE`
- `nix develop --ignore-environment --keep HOME -c just unit-test` with
a writable `GOCACHE`
- `nix develop --ignore-environment --keep HOME -c just lint` with
managed proxy variables and task-local caches
- `nix-shell --run 'just --version'`
- `git diff --check`

flake.lock pins the exact revision of everything the Nix build pulls in
(the package set it takes git, Go and the formatters from, plus a few
helper libraries), much like go.sum does for Go modules. Nothing
refreshes it automatically and no CI job exercises it, so the pins had
quietly drifted the better part of a year behind.
The flake-compat entry also grows a "?rev=...&revCount=..." suffix on
its download URL. That is not a version change: the server hosting the
archive advertises those two values as part of the canonical URL now,
and they only restate the rev and revCount that the same entry already
lists as separate fields. The archive fetched is byte-for-byte identical
either way.
The nixpkgs package set renamed the Nix code formatter: what used to be
called nixfmt-rfc-style is now simply nixfmt, and the old name lives on
only as an alias. Both names resolve to the identical program, so this
doesn't change how anything gets formatted.
The rename comes first because the dependency update in the next commit
makes that alias start printing a deprecation warning, so doing it in
this order means no commit in the history evaluates with one.
PipeCommands ran every command in its own goroutine, each doing
Start/read-stderr/Wait, with nothing ordering one goroutine's Start
against another's Wait. That ordering matters: StdoutPipe registers the
parent's read end in cmd.parentIOPipes, and Cmd.Wait closes those
descriptors when it returns. The next command's Stdin is that very
*os.File, and exec passes a user-supplied *os.File through untouched, so
Start hands the child whatever the fd happens to be at that moment. If
the producer finished and got reaped before the consumer's goroutine
reached Start, that fd was already closed, File.Fd() returned -1, and
the child was started with fd 0 closed -- reading nothing at all.
The only caller is the pre-2.35 fallback in SaveStagedChanges, which
pipes `git stash show -p` into `git apply -R`. Losing that race left git
apply with an empty patch, so it failed with "unrecognized input", the
following `git stash drop` never ran, and the user was left with a stray
stash entry. This turned up as a flaky stash/stash_staged on the git
2.32.0 CI job; the newer-git jobs take the `git stash push --staged`
path and never reach this code.
Starting every command up front removes the race, and collecting stderr
into buffers lets exec's own copying goroutines do the work. That also
fixes two lesser problems in the same function: finalErrors was appended
to from several goroutines without synchronization, and a failed Start
was only logged, so a pipeline that never ran reported success.
