* feat(server): LSP foundation infra — feature flag, JSON-RPC framer, process limits
Phase 3 base layer (tasks 18-20 of editor-lsp-foundation):
- src/server/services/lspFeatureFlag.ts: local opt-in switch.
spec called for `feature('LSP_FOUNDATION')` from `bun:bundle`, but
that table is build-time vendored from upstream Anthropic CLI and
fork code can't register new flag names there. So Phase 3 ships its
own check: dev (NODE_ENV !== 'production') is on by default; prod
is opt-in via `CLAUDE_CODE_LSP=1` env var. Pure function so unit
tests can stub `process.env` directly. 5/5 tests pass.
- src/server/services/lspJsonRpc.ts: minimal Content-Length-framed
JSON-RPC. encodeLspFrame(payload) emits the wire bytes;
LspFrameDecoder accepts arbitrary stream chunks (LSP servers split
frames mid-header / mid-body / multiple-per-chunk) and yields
complete frames per push(). Throws LspFrameDecodeError on missing
or non-numeric Content-Length. ~110 lines, no vscode-jsonrpc
dependency. 10/10 tests pass.
- src/server/services/lspProcessLimits.ts: poll-fallback strategy
(5 s sample interval, terminate after 2 consecutive overages).
spec also lists posix-rlimit and windows-job-object — those need
native bindings or N-API plugins we don't carry yet, so this PR
ships poll-fallback only and exposes a stable LspProcessLimits
interface so a future PR can plug in native strategies without
touching call sites. Sampler is abstract (manager passes a real
ps/Get-Process wrapper in production; tests pass a synthetic
array). 5/5 tests pass.
Tested:
- bun test src/server/services/lspFeatureFlag.test.ts (5/5)
- bun test src/server/services/lspJsonRpc.test.ts (10/10)
- bun test src/server/services/lspProcessLimits.test.ts (5/5)
_Requirements: 7.2, 7.4, 15.3 (adapted)_
* feat(server,desktop): LspManager + LspStatusIndicator (Phase 3 wave 2)
Phase 3 main pieces (tasks 21-27 of editor-lsp-foundation):
Server:
- src/server/services/lspManager.ts: LspManager service. Per-workspace
lazy spawn via injected LspClientFactory; sha-clean state machine
(starting -> ready -> unavailable with 5 reasons). mapLspSeverity
maps LSP wire severity 1-4 -> error/warning/info/hint, anything
else -> error. makeDiagnosticComparator orders by severity ->
in-edited-file -> path -> line -> column. truncateDiagnostics
caps at top-20 entries / 5 distinct files. Idle eviction
(default 600 s) + restart cap (2 attempts in 60 s rolling window
-> restart-cap-exhausted). probeHostCommand from prerequisitesService
is reused.
- src/server/services/lspManager.test.ts: 18 tests covering severity
map / comparator / truncation / spawnIfNeeded gate / prereq-missing /
init-failed / ready+diagnostics flow / shutdownWorkspace /
onStateChange listeners / getPrerequisites delegation / sorted+
truncated diagnostics on real flow.
- src/server/events/lspStateChanged.ts: type-only WS event shape
for `lsp.state.changed` so producers and consumers stay aligned.
- src/server/api/sessions.ts: GET /api/sessions/:id/lsp/state. Gated
by isLspFeatureEnabled() — returns 404 FEATURE_DISABLED in
production unless CLAUDE_CODE_LSP=1.
Desktop:
- desktop/src/types/lsp.ts: desktop-side mirror of LSP wire types.
Mirrored manually rather than imported across boundaries because
there's no shared types module yet.
- desktop/src/components/workspace/LspStatusIndicator.tsx: status
pill + dropdown. CheckCircle / AlertCircle / Loader2 / AlertTriangle
via lucide-react (already a dep). Labels: "Ready" / "N errors
detected" / "9999+ errors detected" cap / "Starting language
server…" / "Language server unavailable". Single context action:
prereq-missing -> Install... button; other unavailable -> Retry.
Dropdown lists diagnostics with messages truncated at 200 chars,
empty list shows "No diagnostics". Keyboard a11y (Tab/Enter/Space/
ArrowUp/ArrowDown/Esc) + aria-live polite mirror.
- desktop/src/components/workspace/LspStatusIndicator.test.tsx: 11
RTL tests covering all five state visuals + error count cap +
Install vs Retry action gating + dropdown empty state + message
truncation + keyboard activation + aria-live mirror.
Stability fix:
- src/server/services/lspProcessLimits.test.ts: bumped sleep from 20 ms
to 60 ms in the "swallows sampler error" test — Windows + bun
scheduler occasionally fails to fire 5 ms intervals twice within
20 ms. 5/5 stable now.
Tested:
- bun test src/server/services/lspFeatureFlag.test.ts (5/5)
- bun test src/server/services/lspJsonRpc.test.ts (10/10)
- bun test src/server/services/lspProcessLimits.test.ts (5/5)
- bun test src/server/services/lspManager.test.ts (18/18)
- bun run test src/components/workspace/LspStatusIndicator.test.tsx (11/11)
- bun run lint (tsc --noEmit clean, both desktop and server)
- bun run check:bundle-budget (delta +0.33 KB gz, 99.67 KB headroom)
- bun run build (clean, 1.27s)
Note: pre-existing e2e/business-flow failures (~44) on origin/main
baseline remain untouched by this change.
_Requirements: 6.1-6.5, 7.1-7.6, 9.1-9.5, 12.1-12.4, 13.1-13.10, 15.1, 15.3_
