3s was tight for cold caches on large home directories; 5s still bounds a
stalled mount well below the 30s command budget while cutting false
negatives on slow-but-healthy checkouts.
Opening the source-control panel could freeze the whole sidebar, and the
frozen layout restored itself after every reload, leaving no way out
(issue #369). Three unbounded layers compounded:
- `git status --porcelain -z --untracked-files=all` shipped every row of a
pathological untracked set into one response; the browser main thread
froze on response.json() plus the unvirtualized change list, and the 2s
poll replayed the freeze. status() now caps entries at 2000 and reports
`truncated` (the panel shows a notice, mirroring fs.read's truncation
semantics); worktree change counts inherit the bound for free.
- repoRoots() probed every visible child directory of a non-repo cwd
(e.g. ~) serially, once per git.* call, each with the full 30s command
budget. Discovery now uses a 3s probe timeout, caps probes at 200
directories, and shares one in-flight scan plus a 60s TTL cache per cwd.
- A hung layout persisted `panelOpen: true` with the git tab active, so a
reload remounted straight back into the freeze with no escape hatch.
Loading with `?dsh-sidebar-reset` now drops the persisted layout (and
the shared width) and starts from the default.
statusTruncated copy synced across all 19 shipped dictionaries.
#1 GitView: hide/disable 'open in editor' for external linked worktrees
(path outside session workspace is rejected by the fence); add
isWithinWorkspace client helper for the gate.
#2 DiffTab: untracked diff read resolves against diff.repoRoot (child-repo
paths are repo-root-relative, not cwd-relative); fs.read route threads
selectedRepoOf into resolveGitPath so the host resolves the right base.
#3 GitView: chooseRepo handler mirrors chooseWorktree — clears status/
history/log and bumps generation before async refresh, preventing stale
rows from acting on the newly selected repository.
#4 git.ts: repoRoots/repoRoot compare roots via pathIdentity() (platform-
aware) instead of raw includes(), fixing win32 forward/backslash
mismatch that silently fell back to roots[0].
#5 markdown-images: mask fenced code blocks and inline code spans before
rewriting; only rewrite reference definitions whose label is actually
referenced by image syntax (not plain links). +3 tests.
#6 package.json: downgrade unrun ^0.3.1 → ^0.2.39 (0.3.x requires Node
^22.13, incompatible with declared engines >=20).
#7 market-manifest.spec: shell:true on win32 so execFileSync resolves the
pnpm .cmd shim.
#8 smoke.spec: build html-route URL via encodeHtmlUrl() (production
encoder) so the Windows drive separator is correct.
#9 index.ts git.worktrees route: thread selectedRepoOf so a workspace
container's selected child repo's linked worktrees appear.
The Git panel only ran git status against the session's own worktree,
so when DSH (or any coding agent) created a linked worktree via
'git worktree add' and modified files there, the sidebar's Git panel
stayed empty - no changed files, no diff, nothing to commit.
Enumerate all linked checkouts of the session repository and let the
user select which one the panel targets. Auto-select the dirty linked
worktree when the primary checkout is clean and exactly one linked
worktree has changes (the common DSH agent pattern). Poll status every
2s while the panel is visible so model-authored edits appear without
a manual refresh.
Security: resolveWorktree validates the client-supplied worktree path
against 'git worktree list' before using it as a git -C cwd. Uses -z
porcelain framing, which disables core.quotePath C-style quoting so
non-ASCII checkout paths round-trip losslessly.
Host half (src/index.ts): /sidebar/api JSON API (session cwd, fs tree/read/
write, git status/diff/stage/commit/branch/log/show), /sidebar/file media
route, /sidebar/ws/terminal WebSocket over node-pty; routes share the /api
trust fence (Host-header loopback or connection.trustedHosts).
Client half (src/client): portal-mounted right panel with a per-session
split-pane workbench (recursive row/col splits, draggable dividers, tab
drag-move), tab bar with max-width 160px + plus-menu (explorer/git/terminal
multi-open rules), lazy file explorer rooted at the session cwd, editable
text editor (dirty dot, Ctrl/Cmd+S), image + Markdown preview, xterm
terminal with reconnect, and a VSCode-style git panel. Per-session state
persists to localStorage (dsh-sidebar:v1:<sessionId>). Intercepts the chat
turn-tail produced-files row (priority -1 chain entry) to open files in the
sidebar. UI styled with the dsh --dsw-* theme tokens and ui-primitives.
Build: tsdown emits the host lib plus the __ModuleLoader__ client bundle
(externals = module table words; xterm/css inlined). Tests: 19 unit + smoke
specs (pure state/tree/git parsers + real git/fs integration).
