Session workers hold one view each and lease the locations their conversations work at; the manager runs the owner's mcp.json servers there (stdio per session and location, or shared; HTTP shared by default) and offers their tools as deferred Durable tools found through tool_search. Stdio servers on an environment start through its pi-env daemon, one connection per environment shared by its instances, through cmd.exe on Windows. A project's .pi/mcp.json, read by the worker at each location, may add stdio servers that run there and switch the owner's servers on or off; the manager refuses everything else. A lease gets servers only on environments its session works on. --- apps/p2/docs/handoff.md | 10 +- apps/p2/docs/mcp-durable.md | 668 +++++++++++++++++ apps/p2/docs/p2-notes.md | 48 +- apps/p2/package.json | 2 + apps/p2/plugins/envs/manager.ts | 10 + apps/p2/plugins/mcp/config.ts | 189 +++++ apps/p2/plugins/mcp/contract.ts | 146 ++++ apps/p2/plugins/mcp/environments.ts | 44 ++ apps/p2/plugins/mcp/instances.ts | 346 +++++++++ apps/p2/plugins/mcp/leases.ts | 78 ++ apps/p2/plugins/mcp/package.json | 5 + apps/p2/plugins/mcp/placement.ts | 249 +++++++ apps/p2/plugins/mcp/project.ts | 94 +++ apps/p2/plugins/mcp/server.ts | 388 ++++++++++ apps/p2/plugins/mcp/tools.ts | 114 +++ apps/p2/plugins/mcp/transports.ts | 94 +++ apps/p2/plugins/mcp/windows-command.ts | 49 ++ apps/p2/plugins/mcp/worker.ts | 218 ++++++ apps/p2/plugins/models/fake.ts | 7 +- apps/p2/src/api/v1/index.ts | 1 + apps/p2/src/hosts/plugins.ts | 6 + apps/p2/src/runtime/chord.ts | 13 +- apps/p2/test/fixtures/mcp-server.mjs | 64 ++ apps/p2/test/p2/mcp-environments.test.ts | 55 ++ apps/p2/test/p2/mcp-instances.test.ts | 139 ++++ apps/p2/test/p2/mcp-leases.test.ts | 89 +++ apps/p2/test/p2/mcp-project.test.ts | 93 +++ apps/p2/test/p2/mcp-tools.test.ts | 104 +++ apps/p2/test/p2/mcp-windows-command.test.ts | 55 ++ apps/p2/test/p2/mcp-worker.test.ts | 108 +++ apps/p2/test/p2/mcp.test.ts | 764 ++++++++++++++++++++ apps/p2/test/p2/plugin-layout.test.ts | 3 + package-lock.json | 2 + 33 files changed, 4242 insertions(+), 13 deletions(-) create mode 100644 apps/p2/docs/mcp-durable.md create mode 100644 apps/p2/plugins/mcp/config.ts create mode 100644 apps/p2/plugins/mcp/contract.ts create mode 100644 apps/p2/plugins/mcp/environments.ts create mode 100644 apps/p2/plugins/mcp/instances.ts create mode 100644 apps/p2/plugins/mcp/leases.ts create mode 100644 apps/p2/plugins/mcp/package.json create mode 100644 apps/p2/plugins/mcp/placement.ts create mode 100644 apps/p2/plugins/mcp/project.ts create mode 100644 apps/p2/plugins/mcp/server.ts create mode 100644 apps/p2/plugins/mcp/tools.ts create mode 100644 apps/p2/plugins/mcp/transports.ts create mode 100644 apps/p2/plugins/mcp/windows-command.ts create mode 100644 apps/p2/plugins/mcp/worker.ts create mode 100644 apps/p2/test/fixtures/mcp-server.mjs create mode 100644 apps/p2/test/p2/mcp-environments.test.ts create mode 100644 apps/p2/test/p2/mcp-instances.test.ts create mode 100644 apps/p2/test/p2/mcp-leases.test.ts create mode 100644 apps/p2/test/p2/mcp-project.test.ts create mode 100644 apps/p2/test/p2/mcp-tools.test.ts create mode 100644 apps/p2/test/p2/mcp-windows-command.test.ts create mode 100644 apps/p2/test/p2/mcp-worker.test.ts create mode 100644 apps/p2/test/p2/mcp.test.ts diff --git a/apps/p2/docs/handoff.md b/apps/p2/docs/handoff.md index 6e56d55f7..fd86b18ff 100644 --- a/apps/p2/docs/handoff.md +++ b/apps/p2/docs/handoff.md @@ -65,7 +65,7 @@ npm test # full suite; TUI tests need Node 26, browser tests ``` Environment variables: `docs/p2-notes.md` (Running).

A sign-in replaced by + a newer one is refused. + - `clientMetadataDocuments: { baseUrl, listsRedirectUrl(url) }`; without it, dynamic registration only (p2 remote). + - Start refreshes with the stored client first, whatever the redirect URI; `authorizeMcp` has `refreshOnly`, so a + failed refresh never disturbs a pending sign-in (`3ffb210d9`: the refresh uses the app's `redirectUrl` when the + documents list it; pass `redirectUrl` to `createMcpAuthProvider` too). + - The store's `withRefreshLock` throws `McpRefreshLockBusyError` when the lock stays held (start then goes to the + browser step); other lock errors fail the sign-in.

Worker state: `servers` + and `errors` (the session's leases' project refusals). +- **Project files as text:** the worker sends `/.pi/mcp.json` as read (`{ location, text }`, at most 256 KiB, or + `{ location, error }` when unreadable; absent: none); the manager parses and checks it (`project.ts`) at each + placement. A project override may also turn on an owner server that is `"enabled": false`. +- **Where sessions work:** a lease gets servers only on an environment its session works on as the server records it + (the catalog's session, the subagent store's own locations). This fences stale or confused workers to their machines, + not a compromised worker (see `McpManager`'s doc comment). +- **Environments:** connections through the envs plugin's SSH manager (`EnvManager.connection`), one per environment + and revision; an instance on an environment that is its location's machine gets the location's cwd as its base and + root, otherwise the remote home. Windows: the `cmd.exe` command line goes in `P2_MCP_COMMAND` (the daemon quotes argv + itself and has no verbatim mode). +- **Not watched:** a changed project `mcp.json` is read again at the worker's next `setLocations` (a commit, a move, + the view re-activating), not when the file changes. + +--- + +## 5. WP2: pi-mcp transport over a byte pipe + +**Where:** `packages/mcp`. + +**Why:** p2 runs stdio MCP servers on remote machines through `openProcess()` (WP1). pi-mcp must not depend on pi-env, +so it gets a transport over an abstract pipe that `RemoteProcess` satisfies without an adapter class. + +**Build:** + +1. `src/transports/lines.ts` (new): the newline-delimited JSON-RPC framing now inside `StdioTransport.handleStdout` + (`src/transports/stdio.ts`): accumulate bytes, split at `\n`, strip a trailing `\r`, skip blank lines, enforce + `maxMessageBytes` (default `DEFAULT_MAX_MESSAGE_BYTES`), parse with `parseJsonRpcMessage`, report errors. Plus the + bounded stderr tail (`maxStderrBytes`, default 64 KiB). One class, used by both transports. +2. `src/transports/stdio.ts`: use `lines.ts`. Behavior must not change; `test/stdio.test.ts` must pass unmodified. +3. `src/transports/pipe.ts` (new), exported from `src/index.ts`: + + ```ts + /** A running program's stdio, as `@earendil-works/pi-env`'s `RemoteProcess` provides it. */ + export interface McpPipe { + write(data: Uint8Array | string): void; + closeStdin(): void; + /** Kill the program (and what it started). */ + close(): void; + /** Settles when the program has ended, whatever the reason. */ + readonly exited: Promise; + } + export interface PipeTransportOptions { + /** Start the program; `onStdout`/`onStderr` receive its output from then on. */ + open(handlers: { onStdout(bytes: Uint8Array): void; onStderr(bytes: Uint8Array): void }): Promise; + maxMessageBytes?: number; + maxStderrBytes?: number; + onStderr?: (chunk: string) => void; + /** After closing stdin, how long the program may take to exit before `close()` kills it. Default 2000. */ + closeTimeoutMs?: number; + } + export class PipeTransport extends TransportEvents implements McpTransport { ... } + ``` + + - `start()` calls `open`; a rejection rejects `start()`. Once `exited` settles, an incomplete trailing message is an + error (as in `StdioTransport`), then `emitClose()`. + - `send()` writes `JSON.stringify(message) + "\n"`; after `close()` or the program's end it throws + `McpConnectionClosedError`. + - `close()`: MCP's stdio shutdown: `closeStdin()`, wait for `exited` up to `closeTimeoutMs`, then `close()`. + - `stderr` getter with the tail, like `StdioTransport`. +4. README (`packages/mcp/README.md`): a short section with the pi-env example: + + ```ts + const transport = new PipeTransport({ + open: (handlers) => openProcess(connection, { cwd, argv, ...handlers }), + }); + ``` + +5. `CHANGELOG.md`: `### Added` entry. + +**Tests:** `test/pipe.test.ts` (new): + +- with an in-memory fake `McpPipe`: framing (split chunks, several messages in one chunk, `\r\n`, blank lines), the size + limit, an incomplete message at exit, `send` after close, the shutdown order (stdin closed first; `close()` only after + the timeout; not at all when the program exits in time), `start` rejecting when `open` rejects; +- end to end: a `McpClient` over `PipeTransport` whose `open` spawns `test/fixtures/stdio-server.mjs` with + `node:child_process` (a 20-line adapter in the test) completes `initialize`, `tools/list` and `tools/call`. + +**Done when:** tests pass, `test/stdio.test.ts` unchanged and green, `npm run check` clean, README and changelog +updated. pi-mcp still has no dependency on pi-env. + +--- + +## 6.

Chord runs it before the object goes live and again inside the commit step of every commit of the object that writes the table, publishing only the diff in that commit's batch; a commit writing no table with a live query runs nothing (`chord.query.runs` counts the runs). Only the object's own tables; the limit is required (`invalid/args` at declaration). A run that fails (a row the code cannot read) is a failed member, reported once as the new `HostError` `query_failed { object, table, error }`, and heals at the next good run. A live query is no native, so an object showing table rows live swaps on reload instead of restarting, as reading them in `self.open` made it. Each touching commit runs the query once (100 rows: about 60 µs, 80 µs watched): not for tables written hundreds of times a second. ### Changed diff --git a/packages/chord/docs/benchmarks.md b/packages/chord/docs/benchmarks.md index 1a18a3bb2..4f5003322 100644 --- a/packages/chord/docs/benchmarks.md +++ b/packages/chord/docs/benchmarks.md @@ -972,3 +972,25 @@ Fix round 1: the bench itself now builds with the app's API and the kinds (its p L5), and every package file's real path is checked against the plugin's `node_modules`.

Chord v2's React bindings gain `usePageState(key, initial)`, `useState`'s pair with the value kept by the page's host under `key` instead of the component: a component of a reloaded web plugin is a new function and remounts (its `useState` starts over), and page state is what survives (a half-typed message, a scroll position); any value, never on the wire, gone with the page. `TuiScope` gains `pageState(key, initial)` on the same per-host store, its changes calling the scope's `changed`. - Chord v2 reports mistakes that waited silently through `onError` (decision "Mistakes that wait are reported at once"): `unbound_long { waitingFor, error, since }`, a request waiting unbound (a type or registry not served here, not at its version, a registry whose first `compose` threw) once after 5 s, on one timer per host (it keeps waiting until its `readyTimeout`); `registry_undeclared { registry, plugins }`, a registry with contributions and no provider at a publication (`load`, a reload's commit) or when a host-lifetime object's contributions enter, naming the contributing plugins, again only once they change; `transaction_cancelled { object, error }`, a document change or transaction that did not commit because the context it was started with ended first (a root whose `fn` returned, a caller that cancelled, its object's end), besides rejecting. - Chord v2 gains live queries: `self.query(table, q, limit)` in the factory of a table's owner is a watchable of the query's rows (at most `limit`, in its order), usable as a state member and a derive source. Chord runs it before the object goes live and again inside the commit step of every commit of the object that writes the table, publishing only the diff in that commit's batch; a commit writing no table with a live query runs nothing (`chord.query.runs` counts the runs). Only the object's own tables; the limit is required (`invalid/args` at declaration). A run that fails (a row the code cannot read) is a failed member, reported once as the new `HostError` `query_failed { object, table, error }`, and heals at the next good run. A live query is no native, so an object showing table rows live swaps on reload instead of restarting, as reading them in `self.open` made it. Each touching commit runs the query once (100 rows: about 60 µs, 80 µs watched): not for tables written hundreds of times a second. +- Chord v2 gains messages and languages in the app kit (design §23): `defineMessages(namespace, { en: {...}, de: {...} })` returns a typed `t(key, ...args)` (the first catalog types the others: a missing key, an unknown one or a wrong argument is a type error; values are strings or functions), `t.message(key, ...args)` builds a message as data (`MessageData`, `{ namespace, key, params }`, for state members typed with `MessageSchema`), `t.render(message)` renders one (a foreign namespace or an unknown key from a link shows the key), `t.translations` lists its catalogs, and `MessagesOf<typeof t>` types a translation. The `Translations` registry takes a list of `{ namespace, locale, messages, override? }` per contributor (one catalog per namespace and locale: the first by plugin name wins, reported; `override: true` wins); a missing key falls back down the locale's chain (`pt-BR`, `pt`) to the first catalog, reported once. `LocaleChoice` keeps one locale per principal on the server (the theme choice's store, now shared as one preference); a client follows it with `followActiveLanguage`, defaulting to `navigator.languages` on a page and the system locale in the terminal (`startTerminal`'s `locales`), matched against the catalogs, switched live. `useMessages(t)` (`/react`) and `TuiScope.messages(t)` (`/tui`) render in the host's language and re-render or redraw on a change; `startPage` sets `lang` and `dir` on the page (`followLanguage`, `/web`); `formatTime` and `formatNumber` use `Intl` in the language being rendered. The kit serves `Translations` on the server, workers, pages and terminals and `LocaleChoice` on the server; client errors gain `{ kind: "messages", report }`. ### Changed diff --git a/packages/chord/README.md b/packages/chord/README.md index d73439b99..6f87b6db9 100644 --- a/packages/chord/README.md +++ b/packages/chord/README.md @@ -15,15 +15,15 @@ The design, the rule book for all of this, is [docs/design.md](docs/design.md). | Import | Contents | Runs in | |--------|----------|---------| -| `@earendil-works/chord` | Contracts (`local`, `remote`, `method`, the schema builders), errors (`ChordError`, `isChordError`), hosts and facets (`createHost`, `defineFacet`), documents (`defineState`), derives and natives (`constant`, `mapShared`), routines and jobs (`defineJob`), links (`memoryLinkPair`, `ipcLink`, `webSocketLink`), registries (`defineRegistry`), the store (`openStore`, `defineTable`, queries, export and import), and the client surfaces' shared part (`Themes`, `ThemeChoice`, `WebScripts`, `TuiScripts`). | Node and browsers | +| `@earendil-works/chord` | Contracts (`local`, `remote`, `method`, the schema builders), errors (`ChordError`, `isChordError`), hosts and facets (`createHost`, `defineFacet`), documents (`defineState`), derives and natives (`constant`, `mapShared`), routines and jobs (`defineJob`), links (`memoryLinkPair`, `ipcLink`, `webSocketLink`), registries (`defineRegistry`), the store (`openStore`, `defineTable`, queries, export and import), and the client surfaces' shared part (`Themes`, `ThemeChoice`, `WebScripts`, `TuiScripts`, messages and languages: `defineMessages`, `Translations`, `LocaleChoice`, `formatTime`, `formatNumber`). | Node and browsers | | `@earendil-works/chord/http` | HTTP: a Web-standard `fetch` handler (`createHttp`) built from the routes, wraps and sockets plugins contribute to the registry `Http`, authenticators (`Authenticators`), responses as descriptions, a security baseline on by default, Chord's Node listener and `nodeRequest`, the links endpoint. | Node | | `@earendil-works/chord/workers` | Workers: `createWorkers` runs a forked worker per address of a host kind, started on demand and stopped when idle; `workerMain` is a worker's entry; `processLock`. | Node | | `@earendil-works/chord/plugins` | Plugins: discovery, builds with esbuild (`buildFacet`), evaluation, the watcher, rollouts, `createPlugins`, `installPlugin`, `testPlugin`, `pluginFile`. | Node | | `@earendil-works/chord/plugins/runtime` | `createPluginRuntime`: loads built plugins without esbuild (a worker's side). | Node | | `@earendil-works/chord/app` | The app kit: `startServer`, `startWorker`, the start-data objects, sessions and the owner's sign-in, device pairing, files, export and import per address, optional plugins (users, invites, ephemeral login). | Node | | `@earendil-works/chord/surfaces` | The client surfaces' server side: `webSurface` (base bundle, plugin scripts, the page) and `tuiSurface` (the terminal surface). | Node | -| `@earendil-works/chord/web` | The web surface's browser side: `startPage` in the app's web entry, `followThemes`. | Browsers | -| `@earendil-works/chord/react` | Optional React bindings: `HostProvider`, `useHold`, `useWatch`, `useRefState`, `useRegistry`, `usePageState`, `watchStore`. | Browsers | +| `@earendil-works/chord/web` | The web surface's browser side: `startPage` in the app's web entry, `followThemes`, `followLanguage`. | Browsers | +| `@earendil-works/chord/react` | Optional React bindings: `HostProvider`, `useHold`, `useWatch`, `useRefState`, `useRegistry`, `usePageState`, `useMessages`, `watchStore`. | Browsers | | `@earendil-works/chord/tui` | The terminal surface's sandbox side: `startTerminalRuntime` in the app's terminal entry, `BridgeTerminal`, `TerminalTheme`, `TuiScope`. | Node (sandboxed) | | `@earendil-works/chord/tui/launcher` | The terminal launcher, the trusted side of a terminal client: `startTerminal`, `requireSandboxNode`. | Node | | `@earendil-works/chord/context` | Explicit cancellation, telemetry, and invocation values: `BACKGROUND_CONTEXT`, `withCancel`, `withAbortSignal`, `withoutAbortSignal`, `withTelemetry`, `traceIn`, `withContextValue`, `awaitWithContext`. | Node and browsers | diff --git a/packages/chord/docs/decisions.md b/packages/chord/docs/decisions.md index 919814eb6..d9c8e4017 100644 --- a/packages/chord/docs/decisions.md +++ b/packages/chord/docs/decisions.md @@ -2419,7 +2419,21 @@ validation and copies the v2 kernel added around Delta. state, notices, tool summaries and errors shown to people (a code plus parameters); each client renders it with `t.render` in its own language (checked at runtime across a link: an unknown key shows the key).

charset=UTF-8 Content-Transfer-Encoding: 8bit In RPC mode, `shutdownHandler` only set a `shutdownRequested` flag. That flag was checked in two places: after a stdin command was handled and on `agent_settled`. If an extension called `ctx.shutdown()` while the session was idle (for example from a timer), neither check ever ran. The process stayed alive until the client sent another command. Interactive mode already shuts down right away in this case. Changes in `packages/coding-agent/src/modes/rpc/rpc-mode.ts`: - **One check for all paths:** `checkShutdownRequested()` shuts down only when a request is pending, input is attached, no command is being handled, and the session is idle. Each of those ending calls it again: command completion, prompt settle, `agent_settled`, and input attach. - **Idle requests:** the shutdown handler schedules the check on the next tick, so the requesting handler finishes first. The conditions are checked when the tick runs, not when it is scheduled: a stdin command that arrives in between is handled first, and shutdown follows when it finishes. - **Requests during startup:** a request made before input is attached (for example a synchronous `ctx.shutdown()` in `session_start`) is checked once the input reader is attached. - **Requests during a command:** shutdown waits until the command finishes, including extension commands. A `prompt` command returns before `session.prompt()` settles, so it stays counted as in flight until the prompt settles, and the shutdown check runs then. This also fixes an existing ordering problem: an extension command that called `ctx.shutdown()` could exit the process before its `prompt` response was written. - **Repeated requests:** `checkShutdownRequested()` does nothing once shutdown has started, so a second `ctx.shutdown()` does not call `process.exit` in the middle of async cleanup. A second stdin EOF or signal still forces exit, as before. Shutdown requested during a running turn is still handled on `agent_settled`, as before. A request made while an extension-started compaction runs (not idle, no run to settle) still waits for the next command or run; `docs/rpc.md` and `docs/extensions.md` note this. Docs (`docs/rpc.md`, `docs/extensions.md`) and the CHANGELOG are updated. ## Testing - Added three tests to `test/rpc-prompt-response-semantics.test.ts`: - an async `ctx.shutdown()` on an idle session exits; - an extension command that calls `ctx.shutdown()` gets its `prompt` response written before exit; - a command that arrives after an idle request but before the scheduled check runs gets its response written before exit. All three fail without the change and pass with it. - `npm run check` passes. All `test/rpc*` tests pass. - In `./test.sh`, all coding-agent tests pass. The only failures were timeouts in durable/harness tests (`store-storage`, `tools-images`, connection close), which this change does not touch. - Reproduction from the issue: run `pi --mode rpc --no-session -ne -e ./shutdown-probe.mjs` with stdin held open and nothing sent. - Before the change, the process stayed alive until a timeout killed it (exit 124). - After the change, `session_shutdown` fires and the process exits with code 0. - A synchronous `ctx.shutdown()` in `session_start` also exits with code 0.

The JSON branch called `response.json()`, which buffered and parsed the whole body with no size check. A server could send an oversized message as plain JSON, and the same content sent as SSE would have been rejected. A new helper, `readBodyText(response, maxBytes)`, reads a body through a reader and decodes each chunk as it arrives. Once the body goes over `maxBytes`, it cancels the rest and returns only the first `maxBytes` bytes, marked as truncated. Counting during the read also covers chunked replies that have no `Content-Length`. `TextDecoder` strips a leading BOM, as `response.json()` does. Two places use it: - JSON replies: if the body is truncated, `send()` throws `MCP JSON response exceeds N bytes` (default 16 MiB). Bodies within the limit are parsed as before. - HTTP error bodies (`checkResponse`): before, `response.text()` read the whole error body and then cut it to 8 KiB. A huge or endless error body was fully buffered, or never finished. Now only the 8 KiB excerpt is read and the rest is cancelled. The excerpt is decoded from the kept bytes only, so it does not keep the whole body alive (#9265). Testing (`packages/mcp/test/streamable-http.test.ts`): - `applies maxMessageBytes to JSON responses`: with a 512-byte limit, a small reply is accepted and a 2 KB reply is rejected. Fails without the fix. - `decodes JSON responses split inside a BOM and a multi-byte character`: the body arrives one byte per chunk. - `reads only an excerpt of HTTP error bodies and cancels the rest`: an endless 500 body yields an 8 KiB excerpt and is cancelled. Without the fix it never finishes. - All MCP tests pass; `npm run check` passes.

The code comes from a loopback callback server (`listenForLoopbackSignIn()`, `waitForLoopbackSignIn()`), the application's own callback route, or a pasted redirect URL (`responseFromRedirectUrl()`). Client ID Metadata Documents (`clientMetadataDocuments`) and the client name are the caller's. Aborting a sign-in's `signal` also stops `startMcpSignIn()` while it waits for the refresh lock; a store's `withRefreshLock()` throws `McpRefreshLockBusyError` when another process holds the lock too long, which makes `startMcpSignIn()` skip the refresh, while any other lock failure fails the sign-in. Also added `createMcpAuthProvider()`, which refreshes tokens once across requests and, through `McpOAuthServerStore.withRefreshLock()`, across processes; its `redirectUrl` option names a redirect URI the application signs in with, so tokens from a Client ID Metadata Document that lists only an https callback route can be refreshed. Also added the `refreshOnly` option of `authorizeMcp()`, which refreshes without registering a client or replacing a pending authorization's `state` and PKCE verifier. - Added helpers that let applications name and configure MCP tools like pi's coding agent, moved from it: `createMcpToolName()` (`mcp__<server>__<tool>`, sanitized, with a hash suffix for long or colliding names) and `mcpNamespace()`; `normalizeMcpInputSchema()`, which makes an input schema an object schema; `limitMcpContent()` and `MCP_OUTPUT_MAX_BYTES`, which cut model-facing text over 20KB in the middle and optionally save the full text through a caller's `McpOutputSaver`; and `validateMcpServerConfig()`, which validates one entry of the `mcpServers` configuration shape (stdio, Streamable HTTP, `oauth`, `enabled`, `description`, `timeout`), returns the entry tagged with its transport, and keeps the application's own fields for it to check afterwards. `isMcpServerOverride()` recognizes entries that only override a server defined elsewhere. +### Fixed + +- Fixed Streamable HTTP `application/json` responses bypassing `maxMessageBytes`; oversized JSON responses are now cancelled and rejected like oversized SSE events ([#11335](https://github.com/earendil-works/pi/issues/11335)) +- Fixed Streamable HTTP errors reading the whole HTTP error body; only the first 8 KiB kept in the error is read, and the rest is cancelled + ## [1.5.0] - 2026-11-02 ### Changed @@ -18,8 +23,6 @@ - OAuth metadata parsing and `startAuthorization()` now accept only `http:` and `https:` URLs.

It never disposed the session runtime, so extensions never got `session_shutdown`. If an extension cleans up a timer or a socket in that handler, the resource stays open and the process never exits after printing the timings. This change calls `await runtime.dispose()` right after `interactiveMode.stop()` in the benchmark path. That is the same order a normal interactive quit uses: stop the TUI, then dispose the runtime. No test was added. Nothing in the test suite covers the startup benchmark path, and that path needs a real TTY. Testing: - `npm run check` passes. - I wrote an extension that starts a `setInterval` in `session_start` and clears it in `session_shutdown`. Then I ran `PI_STARTUP_BENCHMARK=1 PI_TIMING=1 pi --offline -ne -e ./ext.ts` in a terminal, wrapped in `timeout --foreground 15`: - before the change: the timings print, then the process hangs until the timeout (exit 124); - after the change: it exits 0. - Without extensions it exits 0 both before and after.

Problem: Paseo stops pi by closing stdin and sending SIGTERM in the same tick (SIGKILL 2 s later); systemd sends SIGTERM and stdin closes after. In RPC mode: - stdin EOF, then SIGTERM: `shutdown()` removed pi's SIGTERM handler when it started, so the signal killed pi (exit 143) mid-`dispose()`. - SIGTERM, then stdin EOF: the second `shutdown()` call ran `process.exit()`. A pending MCP token refresh was lost: the server had rotated the refresh token, the next pi sent the old one, and the server revoked the grant. Rule after this change: once a shutdown has started, a stdin EOF or a single signal does not interrupt it; a second signal exits at once. SIGKILL still always works. - **RPC mode** (`rpc-mode.ts`): signal handlers stay registered until exit; `shutdown()` runs once and later calls do nothing; the signal handler counts signals and exits only on a repeated one. - **Print mode** (`print-mode.ts`): the final `finally` removed the signal handlers before `disposeRuntime()`, so a signal during the final disposal killed pi. Handlers are now removed after it, `disposeRuntime()` returns the shared in-flight disposal (a signal then waits for it), and a repeated signal exits at once, as before. - **Interactive mode**: unchanged. It already lets a started shutdown finish. Docs (`docs/rpc.md`) and the CHANGELOG are updated. ## Testing - `test/rpc-prompt-response-semantics.test.ts`: EOF then SIGTERM, SIGTERM then EOF (both wait for a slow dispose, exit once with 0 and 143), and EOF then two SIGTERMs (exits at once with 143). All three fail on main. - `test/print-mode.test.ts`: SIGTERM during the final disposal waits for it, a second SIGTERM exits with 143, handlers are removed afterwards. Fails on main. - Real process, `pi --mode rpc` with a `session_shutdown` handler that takes 1 s and real signals: - EOF then SIGTERM: cleanup done, exit 0 (main: no cleanup, exit 143) - SIGTERM then EOF: cleanup done, exit 143 - EOF then two SIGTERMs: exit 143 at once - `npm run check` passes; all `test/rpc*` and `test/print-mode` tests pass. --- packages/coding-agent/CHANGELOG.md | 1 + packages/coding-agent/docs/rpc.md | 2 + packages/coding-agent/src/modes/print-mode.ts | 27 ++++-- .../coding-agent/src/modes/rpc/rpc-mode.ts | 34 ++++--- packages/coding-agent/test/print-mode.test.ts | 33 +++++++ .../rpc-prompt-response-semantics.test.ts | 96 ++++++++++++++++++- 6 files changed, 167 insertions(+), 26 deletions(-) diff --git a/packages/coding-agent/CHANGELOG.md b/packages/coding-agent/CHANGELOG.md index 8718e766e..c8e1875bf 100644 --- a/packages/coding-agent/CHANGELOG.md +++ b/packages/coding-agent/CHANGELOG.md @@ -12,6 +12,7 @@ - A failed token refresh of an MCP connection no longer registers an OAuth client or replaces the PKCE verifier of a sign-in in progress, which made that sign-in fail.

Print mode likewise no longer dies from a signal that arrives during its final cleanup ([#11599](https://github.com/earendil-works/pi/issues/11599)) ## [1.5.0] - 2026-11-02 diff --git a/packages/coding-agent/docs/rpc.md b/packages/coding-agent/docs/rpc.md index d1ae4d8d6..61d8422c0 100644 --- a/packages/coding-agent/docs/rpc.md +++ b/packages/coding-agent/docs/rpc.md @@ -92,6 +92,8 @@ Clients must also handle child-process startup failures, unexpected exits, stder Close the child's stdin to request an orderly shutdown.

See <!-- todo: link --> the docs. ``` rendered both comments. ## Fix - After lexing (next to `trimPartialClosingFences`, before tokens are cached), remove block `html` tokens that contain only comments, recursing into lists and blockquotes. If the removed comment sat between two blank lines, or at the start/end, one blank line is dropped too, so no extra gap remains. - Block HTML with other content keeps rendering as text, with comments stripped (`<!-- x --> text` renders `text`). - Inline comments are skipped; if text before ended with a space, the next text's leading space is dropped (`See <!-- c --> the docs.` renders `See the docs.`). - An unclosed block comment runs to the end of the block (CommonMark), so streamed comments stay hidden. - Other HTML still renders as text (`with <tag> markers`). Parsing stays in marked; the change only filters tokens marked already produced. Cost: one pass over top-level tokens per lex (cached), a regex on `html` tokens only. ## Tests `packages/tui/test/markdown.test.ts`, "HTML comments": compares rendering with comments against the same Markdown without them (issue repro, blank-line handling, multi-line/unclosed, blockquotes and lists, other HTML kept).

Pi renders other Markdown that extensions cannot reach: custom messages, skill blocks, branch and compaction summaries, and the changelog notices (What's New, `/changelog`, Extension Updates, the Update Available note). For example, a transformer cannot rewrite text in an extension's changelog shown under "Extension Updates", because that call site passes no transform. Running every transformer everywhere would break existing ones. The documented example only skips thinking blocks and replaces `-->` with `→`; on a changelog it would turn `<!-- note -->` into `<!-- note →`. Solution: an optional `{ messageTypes }` lists the surfaces a transformer runs on. Without options it runs on the same three types as before. | `messageType` | Surfaces | |---|---| | `user`, `assistant`, `assistant-thinking` | transcript messages (default) | | `custom` (new) | custom messages without a message renderer; expanded skill blocks | | `summary` (new) | expanded branch and compaction summaries | | `changelog` (new) | What's New, `/changelog`, Extension Updates, the Update Available note | ```typescript pi.registerMarkdownTransformer((markdown) => markdown.replaceAll(":warning:", "⚠"), { messageTypes: ["changelog"], }); ``` Details: - Filtering happens in one place, `ExtensionRunner.getMarkdownTransformers()`: each transformer is wrapped so Markdown of unlisted types passes through unchanged. Components still take a plain list of transformers. - Skill blocks and summaries pass only their content to transformers; pi adds its bold header after the transform. - Custom, skill and summary messages now get `messageId` and `timestamp` when loaded from the session. Changelog notices have no session entry, so both are `undefined`. - The built-in Mermaid transformer renders in user and assistant text and now also in summaries, which are model-written like assistant text. It still skips thinking, custom messages and changelogs. - `/hotkeys` does not run transformers. - New exports: `MarkdownMessageType`, `MarkdownTransformerOptions`, `MarkdownTransformerRegistration`. Tests: runner type filtering (default vs. opted in), custom message, skill and summary components (type, header excluded, `messageId`), Mermaid on the new types, and startup notices running `changelog` transformers on What's New and Extension Updates while default transformers are skipped. Related: #11710 (HTML comments in Extension Updates). #11755 already fixed it in the renderer; this PR lets extensions transform those notices in general. --- packages/coding-agent/CHANGELOG.md | 1 + packages/coding-agent/docs/extensions.md | 26 +++++-- .../coding-agent/src/core/extensions/index.ts | 3 + .../src/core/extensions/loader.ts | 11 ++- .../src/core/extensions/runner.ts | 9 ++- .../coding-agent/src/core/extensions/types.ts | 32 +++++++- packages/coding-agent/src/index.ts | 3 + .../components/branch-summary-message.ts | 36 ++++++++- .../components/compaction-summary-message.ts | 36 ++++++++- .../interactive/components/custom-message.ts | 31 +++++++- .../modes/interactive/components/mermaid.ts | 3 +- .../components/skill-invocation-message.ts | 36 ++++++++- .../src/modes/interactive/interactive-mode.ts | 38 +++++++-- .../collapsible-message-components.test.ts | 71 +++++++++++++++++ .../coding-agent/test/custom-message.test.ts | 38 ++++++++- .../test/extensions-runner.test.ts | 32 ++++++++ ...teractive-mode-extension-changelog.test.ts | 77 ++++++++++++++++++- packages/coding-agent/test/mermaid.test.ts | 6 +- 18 files changed, 448 insertions(+), 41 deletions(-) diff --git a/packages/coding-agent/CHANGELOG.md b/packages/coding-agent/CHANGELOG.md index c8e1875bf..4c54742cc 100644 --- a/packages/coding-agent/CHANGELOG.md +++ b/packages/coding-agent/CHANGELOG.md @@ -6,6 +6,7 @@ - `pi update` now lists each updated package with its npm version or git commit change, for example `npm:foo 1.2.0 -> 1.3.0`, and prints `Packages are already up to date` when nothing changed.

charset=UTF-8 Content-Transfer-Encoding: 8bit A schema whose root `$id` was a relative path with a directory part, such as `schemas/tool.json`, could not resolve its local `$ref`s. The `Resolver` constructor applied the root `$id` to `DEFAULT_BASE` once to compute `rootBase`. The compiler, the error explainer and the coercer start from `rootBase` and call `baseFor(root, rootBase)`, which applied the `$id` a second time. Local references therefore resolved against `https://json-schema.invalid/schemas/schemas/tool.json`. The effect was that `compile(schema)` threw `Unresolved $ref #/$defs/count`. With `unresolvedRefs: "reject"`, which is how tool arguments are validated (pi-ai's `validateToolArguments`, used by the agent loop and durable, and durable's `structuredOutput` check), valid arguments were rejected and the tool never ran. Absolute `$id`s and bare names like `tool.json` were not affected, because resolving them twice gives the same URI. The fix: - `rootBase` is now `DEFAULT_BASE`; walkers apply the root's own `$id` through `baseFor`. - `baseFor` indexes the schema before applying an `$id` and then returns the indexed base, so a caller whose base already includes the `$id` cannot apply it again. Without this, `unevaluatedProperties`/`unevaluatedItems` still failed: `build()` passes the already-based node to `annotating()`, which applied the `$id` once more. - The coercer resolves bases through `baseFor` instead of reading `baseOf` directly. Otherwise the `rootBase` change broke the first `parse`/`coerce` of a schema with `$dynamicRef`: the restarted dynamic compiler is not indexed yet, so a relative `$ref` resolved against `DEFAULT_BASE` and conversion was silently skipped. - The explainer drops `$id` from the copy it makes for unevaluated keywords, and resolves `anyOf`/`oneOf` branch `$ref`s against the branch's own base (both threw in `errors()` on main for nested resources with a relative `$id`). Testing: - Regression tests in `validator.test.ts` (relative root `$id` with local `$ref`, with `unevaluatedProperties`/`unevaluatedItems`, error reporting under nested relative resources) and `coerce.test.ts` (first coercion of a `$dynamicRef` schema with a relative external `$ref`). They fail without the change and pass with it. - Full pi-schema suite: 8712 passed. - Independently reviewed against edge cases: draft 7 (inert `$id` beside `$ref`, `#anchor` ids), fragment ids, nested relative chains, anchors, registered schemas referring back to the root, fresh `parse`/`coerce`/`errors` after a dynamic restart.

Memory grew with the size of the matched files, not the output. In the issue's reproduction (8 log files of about 95 MB, one match each, `context: 2`, `--max-old-space-size=1024`), the process ran out of heap after about 10 s. ripgrep already supports context. This change passes `--context N` to rg and formats the `context` events from its JSON output. The tool no longer opens matched files. Details: - After the last allowed match (`limit`), rg still sends that match's trailing context. The tool keeps those lines, then stops rg. A match inside that window is shown as a context line, as before. - Lines past the 50 KB output cap are counted but not stored, since truncation drops them anyway. Match counts, the match-limit notice, and `details.matchLimitReached` stay as before. - rg merges overlapping context, so lines shared by nearby matches are printed once instead of repeated per match. This is the one intended output change. - Context lines are decoded by rg, so UTF-16 files with a BOM show correctly with context (#11423, closed as no-action). Non-UTF-8 lines and paths, which rg sends base64-encoded, are decoded too. Two related grep fixes in the same code: - **Exact match limit:** with exactly N matches and `limit: N`, grep said "N matches limit reached. Use limit=2N". It now sets the notice and `details.matchLimitReached` only after rg sends one more match. Cost: when no further match exists, rg finishes the search instead of being stopped at the Nth match, the same as a search with fewer than N matches. - **Lone CR:** grep removed every `\r` in a line, so `one\rtwo needle` showed as `onetwo needle` and text copied from grep failed to match in edit. It now strips only the line terminator (`\n` or `\r\n`), like the read tool. The TUI still hides CRs when rendering. This updates the expectation in the #11398 test from `beforeprogress` to `before\rprogress`. Breaking: `GrepOperations.readFile` is removed because nothing uses it anymore. rg always ran locally, so this hook never made grep work on a remote backend. Docs now say to override `execute()` for remote search, as the Gondolin example does. Code that passes `readFile` still runs, and the value is ignored. Only code that type-checks an object literal against `GrepOperations` fails to compile. Known remaining differences and limits: - Memory no longer grows with file size or match count, but a single huge matching line (tens of MB) is still buffered whole before being cut to 500 characters. That was already true for `context: 0` on main. Bounding it would mean discarding oversized rg JSON records, which is a separate change. - In a directory search, rg stops reading a file once it finds a NUL byte, so context past that point in a text-looking file that turns binary later is omitted. main reread the file and printed it. Explicit file paths are unaffected. - `details.truncation.totalLines`/`totalBytes` count formatted rows. With deduplicated context, or file names containing newlines, they can differ from main. No renderer or notice displays them. **Testing** - Issue reproduction: before, `FATAL ERROR ... JavaScript heap out of memory`. After, correct output in about 60 ms with 135 MB RSS. - `pattern: "line", context: 3, limit: 100000` over the same 770 MB of logs reports both limit notices and peaks at 154 MB RSS. - New tests in `test/tools.test.ts`: - Merged overlapping context, plus trailing context at the limit including a match inside it. Fails on main. - UTF-16 with context. Fails on main. - Truncation reported when stored output ends exactly at 50 KB. Guards the counting logic. - Matches still counted past the byte cap. Passes on main too; it guards against stopping rg early at the cap. - Huge `context` value accepted. - No limit notice with exactly `limit` matches (with and without context), notice with more. Fails before this change. - Lone CR kept and CRLF stripped, with and without context. Fails before this change. - All 94 tests in the file pass. `npm run check` passes. fixes #9276 This PR is AI-generated. --- packages/coding-agent/CHANGELOG.md | 5 + packages/coding-agent/docs/extensions.md | 2 + packages/coding-agent/src/core/tools/grep.ts | 133 +++++++++-------- packages/coding-agent/test/tools.test.ts | 144 ++++++++++++++++++- 4 files changed, 215 insertions(+), 69 deletions(-) diff --git a/packages/coding-agent/CHANGELOG.md b/packages/coding-agent/CHANGELOG.md index 4c54742cc..062dc9ebb 100644 --- a/packages/coding-agent/CHANGELOG.md +++ b/packages/coding-agent/CHANGELOG.md @@ -2,6 +2,10 @@ ## [Unreleased] +### Breaking Changes + +- Removed `readFile` from `GrepOperations`.

Use limit=0 for more, or refine pattern]`. ls with `limit: 0` listed nothing and printed `(empty directory)`. A fractional limit such as `1.5` printed `1.5 results limit reached. Use limit=3`. Fix: both tools use `Math.max(1, Math.floor(limit ?? DEFAULT_LIMIT))`. grep already clamps to at least 1. The fd path and the custom `glob` path share this value. **2. Notice at exactly N results (#7121).** With 3 matching files and `limit: 3`, fd returned 3 results. find checked `results >= limit` and printed `[3 results limit reached. Use limit=6 for more, or refine pattern]`, even though there were no more files. Fix: find asks fd for `limit + 1` results, shows the first `limit`, and prints the notice only when the extra result exists. ls already worked this way. Custom `FindOperations.glob` now also gets `limit + 1`. The tool shows at most `limit` of the returned results and prints the notice only when more were returned. The interface is unchanged. This follows closed PR #7122 without its unrelated changes. **3. Results past the 50KB cap.** find kept every fd line in memory. `truncateHead` then dropped everything past 50KB. find now handles each line as it arrives. It keeps lines up to the first one past the cap and only counts the rest, as grep does in #11705. Because that first line past the cap is kept, `truncateHead` makes the same truncation decision as before. `details.truncation.totalLines` and `totalBytes` come from the counts, so the notices and `details` are unchanged. Behavior differences: - A custom `glob` that ignores `options.limit` and returns more results used to have all of them shown. Now the tool shows the first `limit` results with the limit notice. - Custom `glob` implementations get `limit + 1` instead of `limit`. - In the fd path, output made only of blank lines with exit code 0 now gives `No files found matching pattern` instead of empty text. fd does not produce such output. **Testing** - New tests in `test/tools.test.ts`: - find: exactly N matches gives no notice, and N+1 matches give the notice with N lines (#7121). Fails on main. - find: `limit` 0, -5, 0.5 and 1.9 each show 1 result with the `1 results` notice. Fails on main. - find with custom `glob`: the operation gets `limit + 1`, and exact and over-limit results give the right output. Fails on main. - find past the byte cap: 300 names of 200 bytes each. `details.truncation` equals `truncateHead` of the full output, except for `content`. Passes on main too; it guards the counting. It fails if the `totalLines` override is removed. - ls: `limit` 0, -5, 0.5 and 1.9 each list 1 entry with the notice. Fails on main. - ls: exactly N entries gives no notice. Passes on main too; it guards the existing behavior. - `test/tools.test.ts` and the find regression suites 3302, 3303 and 6104 pass (110 tests). `npm run check` passes. fixes #7121 This PR is AI-generated. --- packages/coding-agent/CHANGELOG.md | 1 + packages/coding-agent/src/core/tools/find.ts | 64 ++++++----- packages/coding-agent/src/core/tools/ls.ts | 3 +- packages/coding-agent/test/tools.test.ts | 108 ++++++++++++++++++- 4 files changed, 149 insertions(+), 27 deletions(-) diff --git a/packages/coding-agent/CHANGELOG.md b/packages/coding-agent/CHANGELOG.md index 062dc9ebb..f9ca79449 100644 --- a/packages/coding-agent/CHANGELOG.md +++ b/packages/coding-agent/CHANGELOG.md @@ -19,6 +19,7 @@ - Fixed changelog notes repeating on every fresh launch when the installed package version has a prerelease suffix, such as `0.1.5-20261020.7`: the saved version was read as `0.1.0`, so the `0.1.1` to `0.1.5` notes counted as new each time.

That handled LF and CRLF. The SSE spec also allows a lone CR as a line ending, and a stream framed that way never got split. At EOF the whole stream was parsed as a single `id` line, so no event was dispatched, and a tool call answered this way failed with "stream ended without a response". With this change, a line ends at CR, LF, or CRLF. A CR at the end of a chunk ends the line right away, so CR-terminated events are delivered while the stream is still open. A flag skips the LF that may start the next chunk, so a CRLF split across chunks still counts as one line ending. Size limits, dispatch, and error cleanup are unchanged. Testing: - Added two tests to `packages/mcp/test/streamable-http.test.ts`: - LF, CRLF, and CR framing, each sent as one chunk and one character per chunk (which splits every CRLF), plus mixed endings. - A CR-terminated event is dispatched before the stream closes. - Both tests fail without the fix and pass with it. All 127 tests in `packages/mcp` pass. - Feeding `id: r`, `data: {...}`, blank, blank joined by `\r` used to produce no events. It now produces the same event as the LF and CRLF versions. - `npm run check` fails here, but only in `packages/ai` and `packages/chord`, which this change does not touch. It reports nothing in `packages/mcp`; biome and `tsc` are clean on the changed package.

So in a default Alacritty setup, pi fell back to `hyperlinks: false` and rendered Markdown links as `label (url)` instead of clickable OSC 8 links. Alacritty does set two other variables, which this change now checks: - `TERM=alacritty` when its terminfo entry is installed (otherwise `TERM=xterm-256color`); - `ALACRITTY_WINDOW_ID` for the shell on Unix and macOS. This covers the common macOS case where the terminfo entry is missing. The tmux and screen checks still run first, so behaviour inside multiplexers is unchanged. **Testing** - Added a `detectCapabilities` test covering `TERM=alacritty` and `TERM=xterm-256color` with `ALACRITTY_WINDOW_ID`. It fails without the change and passes with it. - `node --test test/*.test.ts` in `packages/tui`: 1121 passing tests. - `npm run check` passes. - Checked `detectCapabilities()` with clean environments: - Before: `TERM=alacritty` and `ALACRITTY_WINDOW_ID=123` both gave `hyperlinks: false`. - After: both give `hyperlinks: true`. - Plain `xterm-256color` and tmux with `ALACRITTY_WINDOW_ID` still give `false`.

That happens on a refused connection, a wrong port, or `https://` against a plain-HTTP server. Node's `fetch` keeps the real reason in `error.cause`, and pi dropped it, so the user had nothing to go on. `LlamaClient` now sends its requests, including the `/models/sse` watch, through a small `fetchServer` helper. When `fetch` fails at the network level, the helper throws `Could not reach llama.cpp server at <url>: <cause>` and keeps the original error as `cause`. Aborts and timeouts are rethrown unchanged. HTTP error responses are handled as before. The same message also improves `/llama` and the model catalog refresh, because they use the same client. **Testing** - Added a test in `test/llama-extension.test.ts` that calls `LlamaClient.list()` against a closed local port and expects the server URL and `connect ECONNREFUSED ...` in the error.

Most Windows terminals handle Ctrl+V themselves and send a bracketed paste. Some terminals have no Ctrl+V paste action and pass Ctrl+V to the program as the raw `0x16` key instead; Tern's embedded terminal is one. In those terminals nothing in pi was bound to `ctrl+v`, so pressing it did nothing and showed no message. This change makes the Windows/WSL default `["alt+v", "ctrl+v"]`. `alt+v` keeps working as before. In terminals that handle Ctrl+V themselves, pi never receives the key, so the extra binding has no effect there. No other default binding uses `ctrl+v`. `docs/keybindings.md` is updated to match. Testing: - Added a test to `test/keybindings.test.ts`. It sets `WSL_DISTRO_NAME`, re-imports the keybindings module, and checks that the paste defaults are `["alt+v", "ctrl+v"]`. It fails without the change and passes with it. - Updated the existing defaults assertion in the same file to match the new value. - `node ../../node_modules/vitest/dist/cli.js --run test/keybindings.test.ts`: 6 passed. - `npm run check`: passes.

That provider caps the GPT-6 family at 272K so requests stay in OpenAI's short-context pricing tier. The Azure provider overrides this cap through `CONTEXT_WINDOW_OVERRIDES`, but that list only covered gpt-5.4, gpt-5.5 and gpt-5.6. As a result, `azure/gpt-6-astra`, `gpt-6-luna`, `gpt-6-sol`, `gpt-6.1-sol` and `gpt-6.1-terra` showed a 272K context window, and pi compacted sessions far earlier than needed. Azure Foundry deploys these models with a 1,050,000-token context window. This change adds the five models to the Azure override list. OpenAI-direct is unchanged. Testing: - Added a test in `packages/ai/test/supports-xhigh.test.ts` that checks each of these Azure models has a 1,050,000 context window. It fails on all five models without the override (5 failed) and passes with it. - After regenerating the model data, the generated Azure catalog lists all five models at 1050000. Before the change they were at 272000. - `npm run check` passes.

Images in messages queued while the agent was busy skipped this step. That covers `steer()`, `followUp()`, `prompt()` with `streamingBehavior`, and RPC `steer`/`follow_up`. Those images were sent and saved at full size. For example, a 1200x9000 PNG stayed 1200x9000, which is over Anthropic's 8000 px limit, and because it is saved in the session it was replayed on every later request. What the change does: - `_queueSteer`/`_queueFollowUp` now mark queued user messages that carry images. - When such a message is delivered (`message_start`), `AgentSession` normalizes its images in place with `_normalizePromptImages`, the same code the idle prompt path uses, and appends the resize hints to its text. This runs before extensions and listeners see the message, before it is saved, and before it is added to the request context. - Doing it at delivery keeps enqueueing synchronous. A slow resize therefore cannot leave a message queued after the run has ended. I hit exactly that when I first tried normalizing at enqueue time. Delivery is also when the resize uses the model current at that moment. - The queue display still matches and removes the message, because matching runs before the text is changed. Testing: - New `test/agent-session-queued-images.test.ts`: a 1200x9000 PNG is queued while the agent is streaming, through `steer()`, `followUp()` and `prompt(..., { streamingBehavior: "followUp" })`. The test checks three things: each saved message has a resized image and the "original 1200x9000, displayed at 267x2000" hint; no request sent to the model contains the original image; and the queue is empty afterwards. It fails without the change and passes with it. - `npm run check` passes. The `agent-session*` tests, the queue- and image-related tests and `test/suite` pass. - Before the change, the saved steer and follow-up messages had `image/png 1200x9000` while the idle prompt had a resized JPEG. After it, all three are resized.

The actual reason is in the `cause` chain, usually two levels down: undici's `TypeError: fetch failed` wraps `connect ECONNREFUSED 127.0.0.1:8080`. pi built `errorMessage` from `error.message` only, so users, print mode, and session files saw only "Connection error." and had nothing to go on. This change adds `withCauseDetail()` in `utils/error-body.ts`: - It walks the `cause` chain, up to 5 levels, and appends the deepest message, plus its `code` if the message doesn't already contain it. For example: `Connection error.: connect ECONNREFUSED 127.0.0.1:8080`. - `normalizeProviderError` applies it only when the error has no HTTP status and no body. That covers every adapter that goes through `formatProviderError`. - The Anthropic adapter's catch block also uses it, since it read `error.message` directly. Errors without a cause come out unchanged. Retry classification still matches, because the message still contains "Connection error". **Testing** - Added tests to `packages/ai/test/error-body.test.ts`: - a synthetic nested cause chain; - adding the code when the message lacks it; - no cause leaves the message unchanged; - a real `openai` SDK call against a closed local port, which now gives `Connection error.: connect ECONNREFUSED 127.0.0.1:<port>`. - Without the source change, the nested-chain test and the real SDK test fail, because the message is just `Connection error.`. - The full `packages/ai` test suite passes, and `npm run check` passes.

That list still stopped at `glm-5.2`. models.dev now has `glm-5.3`, and `qwen-token-plan` and `qwen-token-plan-cn` already list it. Individual did not, because `glm-5.3` was not on its list. This change adds `glm-5.3` to the Individual list and updates the "verified" date in the comment above it. Tests in `packages/ai/test/qwen-token-plan-models.test.ts`: - `glm-5.3` is added to the expected list for the exact-list test. - A new test checks that Individual's `glm-5.3` uses the international Token Plan base URL. It also checks the thinking levels models.dev gives for it: low, high and max. How I tested it: - `npm run generate-models`, then `test/qwen-token-plan-models.test.ts`: all 90 tests pass. Without the change to the list, 3 tests fail. - `npm run check` passes. - Before: `pi --list-models qwen-token-plan-individual` listed `glm-5.2` but not `glm-5.3`. After: it lists both.

Reads and writes follow symlinks to the same real file, but each path alias got its own lock. For example, an agent dir whose `auth.json` is a symlink to a shared file used a different lock than the real file. Two pi processes could then enter the credential-modification section at the same time and refresh the same OAuth token concurrently. This change drops `realpath: false` from the sync and async lock calls, so proper-lockfile resolves the path and every alias of the file uses one lock. Resolving the path needs the file to exist, which is already the case: `ensureFileExists()` runs before either lock is taken. The same `realpath: false` pattern is also in `settings-manager.ts`, `trust-manager.ts`, and `package-manager-cli.ts`. This change leaves those alone. ## Testing - I added a test to `test/auth-storage.test.ts`. It holds the lock on the real `auth.json`, then checks that a backend opened through a symlink alias waits in `withLockAsync` until aborted, and gets `ELOCKED` from `withLock`. Neither path runs the mutation. Without the fix the test fails because the async call enters the lock; with the fix it passes. - `node ../../node_modules/vitest/dist/cli.js --run test/auth-storage test/settings`: 151 tests pass. - `npm run check` passes. - With the reproduction script from the issue, current main prints `symlink alias: ENTERED`; with this change it prints `symlink alias: BLOCKED`. The same-path control prints `BLOCKED` in both cases.

GHSA-g3hv-75wg-m249 (moderate, a ReDoS via globparts amplification) covers every minimatch version below 11.0.1, and there is no patched 10.x release. As a result, `npm audit` fails in every project that installs pi-coding-agent. This change pins `minimatch` to `11.0.3` and regenerates `package-lock.json` and `packages/coding-agent/install-lock/` with `scripts/generate-coding-agent-install-lock.mjs`. minimatch 11 adds one new transitive dependency, `@isaacs/nonrecursive-glob-match@1.0.3`, which has no install scripts. It also moves brace-expansion to ^5.0.12. pi uses minimatch in only two places, `model-resolver.ts` and `package-manager.ts`. Both use the named `minimatch` export, which 11.x keeps unchanged. No new test was added: the change only bumps a dependency, and existing tests cover both places that use it.

A large message arriving in many chunks was therefore copied and scanned again on every chunk. A 12 MiB tool result in 64 KiB chunks took about 350 ms just to frame. Now the reader keeps the bytes of an incomplete message as a list of chunks, with a running byte count, and searches only the new chunk for a newline. When the newline arrives, the chunks are joined once. A line that fits inside a single chunk is sliced directly. The rest is unchanged: the `maxMessageBytes` limit (now checked against the running count), CRLF and blank-line handling, errors for invalid JSON and oversized messages, and the incomplete-message error in `end()`. Testing: - New `packages/mcp/test/lines.test.ts`: - a 1 MiB message fed in 4 KiB chunks calls `Buffer.concat` once (fails on the old code); - a mixed input of multi-byte UTF-8, CRLF, blank lines, an invalid line and several messages gives the same results at every chunk size from 1 byte to the whole input; - reading recovers after an oversized message; - a message without its newline is reported at the end. - `test/lines.test.ts`, `test/stdio.test.ts` and `test/pipe.test.ts` pass. `npm run check` passes. - Micro-benchmark, one message fed in 64 KiB chunks: - before: 1 MiB 5.4 ms, 4 MiB 49.9 ms, 12 MiB 348 ms; - after: 2.2 ms, 7.9 ms, 21.6 ms.

A user `!` command can discard earlier chunks but report `truncated: false` when the retained tail fits within the output limits. The model then receives no truncation notice or full-log path. Track discarded chunks and include that flag in the executor's result for both completion and cancellation. This applies to the current shared finalization path and preserves streaming ANSI handling. Output limits and message format stay unchanged. Related: #2852. Here the complete log is already saved; the incorrect flag hides its path from the model. Validation on main `f1b2e77f5`: - Two deterministic 64 KiB + 44 KiB cases fail without the fix. All three regressions pass with it, checking completion, cancellation, the complete log, model-facing path, and short-output behavior. - Regressions are in `test/bash-executor-truncation.test.ts`; that file and `test/tools.test.ts` pass all 88 tests. - `npm run check`, offline build, and `./test.sh` pass. --- .../coding-agent/src/core/bash-executor.ts | 4 +- .../test/bash-executor-truncation.test.ts | 59 +++++++++++++++++++ 2 files changed, 62 insertions(+), 1 deletion(-) create mode 100644 packages/coding-agent/test/bash-executor-truncation.test.ts diff --git a/packages/coding-agent/src/core/bash-executor.ts b/packages/coding-agent/src/core/bash-executor.ts index 679543ec4..9745ff217 100644 --- a/packages/coding-agent/src/core/bash-executor.ts +++ b/packages/coding-agent/src/core/bash-executor.ts @@ -53,6 +53,7 @@ export async function executeBashWithOperations( ): Promise<BashResult> { const outputChunks: string[] = []; let outputBytes = 0; + let discardedOutput = false; const maxOutputBytes = DEFAULT_MAX_BYTES * 2; let tempFilePath: string | undefined; @@ -95,6 +96,7 @@ export async function executeBashWithOperations( while (outputBytes > maxOutputBytes && outputChunks.length > 1) { const removed = outputChunks.shift()!; outputBytes -= removed.length; + discardedOutput = true; } // Stream to callback @@ -140,7 +142,7 @@ export async function executeBashWithOperations( output: truncationResult.truncated ? truncationResult.content : fullOutput, exitCode: cancelled ? undefined : (exitCode ?? undefined), cancelled, - truncated: truncationResult.truncated, + truncated: discardedOutput || truncationResult.truncated, fullOutputPath: tempFilePath, }; } diff --git a/packages/coding-agent/test/bash-executor-truncation.test.ts b/packages/coding-agent/test/bash-executor-truncation.test.ts new file mode 100644 index 000000000..7c480fe46 --- /dev/null +++ b/packages/coding-agent/test/bash-executor-truncation.test.ts @@ -0,0 +1,59 @@ +import { readFile, rm } from "node:fs/promises"; +import { afterEach, describe, expect, it, vi } from "vitest"; +import { executeBashWithOperations } from "../src/core/bash-executor.ts"; +import { bashExecutionToText } from "../src/core/messages.ts"; + +describe("user bash output truncation (#10164)", () => { + const tempFiles: string[] = []; + + afterEach(async () => { + await Promise.all(tempFiles.splice(0).map((path) => rm(path, { force: true }))); + }); + + // #10164: the retained tail can fit even though earlier output was discarded. + it.each([false, true])("reports discarded chunks when cancelled=%s", async (cancelled) => { + const first = "error: missing build dependency\n".padEnd(64 * 1024, "x"); + const last = "remaining build output\n".padEnd(44 * 1024, "y"); + const controller = new AbortController(); + const result = await executeBashWithOperations( + "cat build.log", + process.cwd(), + { + exec: async (_command, _cwd, { onData }) => { + onData(Buffer.from(first)); + onData(Buffer.from(last)); + if (cancelled) { + controller.abort(); + throw new Error("aborted"); + } + return { exitCode: 0 }; + }, + }, + { signal: controller.signal }, + ); + if (result.fullOutputPath) tempFiles.push(result.fullOutputPath); + // The executor closes its file stream without awaiting its finish event. + await vi.waitFor(async () => { + expect(await readFile(result.fullOutputPath!, "utf-8")).toBe(first + last); + }); + + expect(result.cancelled).toBe(cancelled); + expect(result.output).toBe(last); + expect(result.truncated).toBe(true); + expect( + bashExecutionToText({ role: "bashExecution", command: "cat build.log", timestamp: 0, ...result }), + ).toContain(`[Output truncated.

For example, this input: ```diff -83 await commitRecordingChunk({ +83 const result = await commitRecordingChunk({ ``` was rendered as: ```diff -83 await commitRecordingChunk({ +83 const result = await commitRecordingChunk({ ``` `diffWords()` groups the shared leading spaces into the added segment (`" const result = "`). The existing highlighting logic moved those spaces outside inverse styling, but only appended them to the added line. ## Solution Extract whitespace shared by both lines before calling `diffWords()`, then initialize both rendered lines with that prefix. This preserves indentation without changing the existing word-level highlighting behavior. The existing handling for whitespace that belongs to only one side remains unchanged. Added regression coverage for: - insertion before indented content; - replacement within indented content; - keeping shared indentation outside inverse highlighting. ## Validation - `npm run check` - `./test.sh` - targeted `packages/coding-agent/test/diff.test.ts` (3 tests) --- .../src/modes/interactive/components/diff.ts | 18 +++++++--- packages/coding-agent/test/diff.test.ts | 35 +++++++++++++++++++ 2 files changed, 48 insertions(+), 5 deletions(-) create mode 100644 packages/coding-agent/test/diff.test.ts diff --git a/packages/coding-agent/src/modes/interactive/components/diff.ts b/packages/coding-agent/src/modes/interactive/components/diff.ts index 54e88273d..6c052df7b 100644 --- a/packages/coding-agent/src/modes/interactive/components/diff.ts +++ b/packages/coding-agent/src/modes/interactive/components/diff.ts @@ -20,14 +20,22 @@ function replaceTabs(text: string): string { /** * Compute word-level diff and render with inverse on changed parts. - * Uses diffWords which groups whitespace with adjacent words for cleaner highlighting. - * Strips leading whitespace from inverse to avoid highlighting indentation. + * Separates common indentation before diffing so a leading insertion cannot consume it. */ function renderIntraLineDiff(oldContent: string, newContent: string): { removedLine: string; addedLine: string } { - const wordDiff = Diff.diffWords(oldContent, newContent); + let commonIndentLength = 0; + while ( + commonIndentLength < oldContent.length && + oldContent[commonIndentLength] === newContent[commonIndentLength] && + /\s/.test(oldContent[commonIndentLength]) + ) { + commonIndentLength++; + } - let removedLine = ""; - let addedLine = ""; + const commonIndent = oldContent.slice(0, commonIndentLength); + const wordDiff = Diff.diffWords(oldContent.slice(commonIndentLength), newContent.slice(commonIndentLength)); + let removedLine = commonIndent; + let addedLine = commonIndent; let isFirstRemoved = true; let isFirstAdded = true; diff --git a/packages/coding-agent/test/diff.test.ts b/packages/coding-agent/test/diff.test.ts new file mode 100644 index 000000000..00403a84c --- /dev/null +++ b/packages/coding-agent/test/diff.test.ts @@ -0,0 +1,35 @@ +import { beforeAll, describe, expect, it } from "vitest"; +import { renderDiff } from "../src/modes/interactive/components/diff.ts"; +import { initTheme, theme } from "../src/modes/interactive/theme/theme.ts"; +import { stripAnsi } from "../src/utils/ansi.ts"; + +describe("renderDiff", () => { + beforeAll(() => initTheme("dark")); + + it.each([ + { + name: "text is inserted at the start of a line", + diff: "-83 await commitRecordingChunk({\n+83 const result = await commitRecordingChunk({", + expected: ["-83 await commitRecordingChunk({", "+83 const result = await commitRecordingChunk({"], + }, + { + name: "indented text is replaced", + diff: "-12 const value = oldValue\n+12 const value = newValue", + expected: ["-12 const value = oldValue", "+12 const value = newValue"], + }, + ])("preserves indentation when $name", ({ diff, expected }) => { + const rendered = renderDiff(diff); + + expect(stripAnsi(rendered).split("\n")).toEqual(expected); + }); + + it("does not highlight shared indentation as an insertion", () => { + const rendered = renderDiff( + "-83 await commitRecordingChunk({\n+83 const result = await commitRecordingChunk({", + ); + const inverseInsertion = theme.inverse("const result = "); + + expect(rendered.indexOf("+83 ")).toBeLessThan(rendered.indexOf(inverseInsertion)); + expect(rendered).toContain(inverseInsertion); + }); +}); From c3b938e3e9d320e0977173483c4f3620061dd73a Mon Sep 17 00:00:00 2001 From: Gangqiang Yao <acmerfight@gmail.com> Date: Wed, 4 Nov 2026 17:18:59 +0800 Subject: [PATCH 043/128] fix(coding-agent): reject reload while running or compacting (#9222) Fixes #9221. An extension tool can lose its context when an RPC command or SDK caller reloads the session during tool execution: the tool awaits work, reload invalidates its runner, then `ctx.getSystemPrompt()` throws a stale-context error. The failed tool result is stored in session history. Reject reload when `isStreaming` or `isCompacting` is already set, before shutdown or runner invalidation. This gives RPC and direct callers the same entry checks as the TUI. The production change remains seven lines. #9548 removed the wrapper access behind the original reproduction. The regression exercises the tool's own context access after an await, through both an RPC-style extension command and direct `AgentSession.reload()`. Rejection preserves the successful result in session history and the next provider request. Compaction, tree navigation, and idle reload are also covered. Scope: this guards operations already marked running or compacting. It does not serialize reload with prompt preflight or prevent a new prompt from starting during an ongoing reload. Related: #5735 proposes a broader deferred-reload API. This patch only adds the existing TUI entry checks to the core reload method. Validation on main `f1b2e77f5`: - Without the guard, four regression cases fail and idle reload passes. With it, all five pass. - `npm run check`, offline build, and `./test.sh` pass. --- .../coding-agent/src/core/agent-session.ts | 7 + .../9221-reload-during-tool.test.ts | 186 ++++++++++++++++++ 2 files changed, 193 insertions(+) create mode 100644 packages/coding-agent/test/suite/regressions/9221-reload-during-tool.test.ts diff --git a/packages/coding-agent/src/core/agent-session.ts b/packages/coding-agent/src/core/agent-session.ts index 5d341c4d7..0f5aa1105 100644 --- a/packages/coding-agent/src/core/agent-session.ts +++ b/packages/coding-agent/src/core/agent-session.ts @@ -3763,6 +3763,13 @@ export class AgentSession { } async reload(options?: { beforeSessionStart?: () => void | Promise<void> }): Promise<void> { + if (this.isStreaming) { + throw new Error("Wait for the current response to finish before reloading."); + } + if (this.isCompacting) { + throw new Error("Wait for compaction to finish before reloading."); + } + const oldRunner = this._extensionRunner; const previousFlagValues = oldRunner.getFlagValues(); await emitSessionShutdownEvent(oldRunner, { type: "session_shutdown", reason: "reload" }); diff --git a/packages/coding-agent/test/suite/regressions/9221-reload-during-tool.test.ts b/packages/coding-agent/test/suite/regressions/9221-reload-during-tool.test.ts new file mode 100644 index 000000000..4db68aba5 --- /dev/null +++ b/packages/coding-agent/test/suite/regressions/9221-reload-during-tool.test.ts @@ -0,0 +1,186 @@ +import { fauxAssistantMessage, fauxToolCall } from "@earendil-works/pi-ai"; +import type { ToolResultMessage } from "@earendil-works/pi-ai/compat"; +import { Type } from "typebox"; +import { afterEach, describe, expect, it, vi } from "vitest"; +import { assistantMsg, userMsg } from "../../utilities.ts"; +import { createHarness, getMessageText, type Harness } from "../harness.ts"; + +function deferred(): { promise: Promise<void>; resolve: () => void } { + let resolve!: () => void; + const promise = new Promise<void>((done) => { + resolve = done; + }); + return { promise, resolve }; +} + +// Regression for https://github.com/earendil-works/pi/issues/9221. +describe("reload during an active session operation", () => { + let harness: Harness | undefined; + + afterEach(() => { + harness?.cleanup(); + vi.restoreAllMocks(); + }); + + it.each(["command", "direct"] as const)( + "rejects %s reload without invalidating an active tool's context", + async (source) => { + const started = deferred(); + const released = deferred(); + const shutdown = vi.fn(); + const errors: string[] = []; + let providerResults: ToolResultMessage[] = []; + const h = await createHarness({ + extensionFactories: [ + (pi) => { + pi.on("session_shutdown", shutdown); + pi.registerCommand("reload-runtime", { + description: "Reload extensions", + handler: async (_args, ctx) => ctx.reload(), + }); + pi.registerTool({ + name: "wait_then_succeed", + label: "Wait then succeed", + description: "Use the tool context after waiting", + parameters: Type.Object({}), + execute: async (_id, _params, _signal, _update, ctx) => { + started.resolve(); + await released.promise; + // #9221: the tool itself can still use ctx after an async operation. + ctx.getSystemPrompt(); + return { content: [{ type: "text", text: "tool succeeded" }], details: {} }; + }, + }); + }, + ], + }); + harness = h; + await h.session.bindExtensions({ + mode: "rpc", + onError: (error) => errors.push(error.error), + commandContextActions: { + waitForIdle: () => h.session.waitForIdle(), + newSession: async () => ({ cancelled: true }), + fork: async () => ({ cancelled: true }), + navigateTree: (targetId, options) => h.session.navigateTree(targetId, options), + switchSession: async () => ({ cancelled: true }), + // Match RPC's ctx.reload binding to the core reload entry point. + reload: () => h.session.reload(), + }, + }); + const runner = h.session.extensionRunner; + h.setResponses([ + fauxAssistantMessage(fauxToolCall("wait_then_succeed", {}), { stopReason: "toolUse" }), + (context) => { + providerResults = context.messages.filter((message) => message.role === "toolResult"); + return fauxAssistantMessage("done"); + }, + ]); + + const prompt = h.session.prompt("run the tool"); + await started.promise; + try { + if (source === "command") { + await h.session.prompt("/reload-runtime", { source: "rpc" }); + } else { + await expect(h.session.reload()).rejects.toThrow( + "Wait for the current response to finish before reloading.", + ); + } + } finally { + released.resolve(); + await prompt; + } + + const persistedResults = h.sessionManager + .getEntries() + .flatMap((entry) => + entry.type === "message" && entry.message.role === "toolResult" ?

Disposing a runtime during tool execution disconnects persistence before the interrupted turn settles, leaving a stored assistant tool call without its result. Await `session.abort()` before shutdown and disposal so the interrupted tool result and final assistant message are persisted. This matches `teardownCurrent()`. `AgentSession.dispose()` remains synchronous. Like the existing replacement path, the wait has no timeout; handling tools that ignore cancellation is outside this change. Related: #9986 concerns results for tool calls skipped during a mid-session abort. This fix preserves the result of an already-running tool during runtime shutdown. Validation on main `f1b2e77f5`: - The regression fails without the fix and passes with it, checking the durable message order and `Operation aborted` result immediately after `dispose()` returns, before awaiting the prompt. - `npm run check`, offline build, and `./test.sh` pass. --- .../src/core/agent-session-runtime.ts | 1 + ...24-runtime-dispose-tool-settlement.test.ts | 82 +++++++++++++++++++ 2 files changed, 83 insertions(+) create mode 100644 packages/coding-agent/test/suite/regressions/9124-runtime-dispose-tool-settlement.test.ts diff --git a/packages/coding-agent/src/core/agent-session-runtime.ts b/packages/coding-agent/src/core/agent-session-runtime.ts index 81c4264cf..cf06d5fce 100644 --- a/packages/coding-agent/src/core/agent-session-runtime.ts +++ b/packages/coding-agent/src/core/agent-session-runtime.ts @@ -402,6 +402,7 @@ export class AgentSessionRuntime { } async dispose(): Promise<void> { + await this.session.abort();

Proxies such as nginx with `underscores_in_headers off` silently drop headers with underscores, and Envoy can be configured to reject them. Codex now sends `session-id`, and the `openai-codex-responses` path already followed it (#4967). With the default `openai` session-affinity format, `openai-responses` now sends `session-id`. `x-client-request-id` and `prompt_cache_key` are unchanged. The `openai-nosession` and `openrouter` formats behave as before. The compat schema description for `sessionAffinityFormat` (`openai-responses`) and `docs/models-configuration.md` are updated to match. Not changed: `openai-completions` still sends `session_id`. I did not check whether xAI or other backends on the Responses API depend on the underscored name. Their `prompt_cache_key` is still sent, so prompt caching should not depend on the header. Testing: - `test/openai-responses-compat.test.ts` now captures `session-id`. It also checks that `session_id` is no longer sent, and the explicit-override test uses the new name. `test/xai-responses.test.ts` expects `session-id` and no `session_id`. - Without the source change, these tests fail (3 failures); with it, both files pass (50 tests). - `npm run check` passes. - The full `packages/ai` suite passes, except `generate-models-strict.test.ts`. That failure is unrelated: the test depends on live model catalog data.

That function's extension table had no entries for Dart, Nix, or Groovy. Their highlight.js grammars are loaded at startup, but the lookup returned `undefined`, so these files were shown as plain uncolored text. This change adds `dart → dart`, `nix → nix`, `groovy → groovy`, and `gradle → groovy` to the table in `packages/coding-agent/src/modes/interactive/theme/theme.ts`. HTML export keeps its own separate extension map and a vendored highlight bundle without a Dart grammar. This change does not touch either. ## Testing - Added a test to `test/syntax-highlight.test.ts` that checks the new extension mappings. It fails without the fix and passes with it. - `node ../../node_modules/vitest/dist/cli.js --run test/syntax-highlight.test.ts` passes. - Before, `getLanguageFromPath("a.dart")` (and `.nix`, `.groovy`, `build.gradle`) returned `undefined` from the built dist. After, they return `dart`, `nix`, `groovy`, and `groovy`. - `npm run check` reports 6 type errors in `packages/ai/test` (model ID types). Main without this change has the same 6 errors.

Previously, completion markers were only recognized in the exact `[DONE:n]` form inside visible text blocks, so steps frequently never got checked off during execution. ## Changes - **`getTextContent`** now reads `thinking` blocks as well as text blocks, so `[DONE:n]` tags emitted during reasoning are honored. - **Marker tolerance** (`extractDoneSteps`): accepts `[DONE: 1]`, `[DONE 1]`, `Done: n`, and prose phrasings like "Step n done / is complete / finished" — all adjacency-anchored so negations ("Step 9 is not done") never match. - **Whole-plan fallback** (`allStepsComplete`): if the run's final message says the plan is done (e.g. "All steps complete"), all remaining steps are marked at `agent_end`. - **Plan extraction dedup**: only the last `Plan:` section is extracted, so a plan drafted in a thinking block no longer duplicates the steps from the text block. - **No more truncation**: step text is kept in full (previously cut at 50 chars); the widget truncates for display only. The execution prompt now shows the complete step text. - **No more dropped steps**: steps whose text starts with a backtick (e.g. `1. \`index.ts\` — …`) are no longer skipped. - **Widget refresh** happens on every turn instead of only when a marker matched. - **Plan-complete card** is delivered with `nextTurn` instead of triggering an extra LLM turn. ## Tests `packages/coding-agent/test/plan-mode-utils.test.ts` updated for the new behavior (truncation, backtick steps, marker-count semantics) and extended with coverage for the new cases (marker variants, prose phrasings, negation safety, thinking-draft dedup, markdown titles, whole-plan completion). All 43 tests in `plan-mode-utils.test.ts` + `plan-mode-extension.test.ts` pass (`npx vitest run`). Note: the repo-wide type-check currently fails on `main` with pre-existing `ModelCatalog`/`never` errors unrelated to this change; this branch adds none (same count with and without the diff). --- .../examples/extensions/plan-mode/index.ts | 36 +++++++----- .../examples/extensions/plan-mode/utils.ts | 58 ++++++++++++++----- .../coding-agent/test/plan-mode-utils.test.ts | 57 +++++++++++++++--- 3 files changed, 113 insertions(+), 38 deletions(-) diff --git a/packages/coding-agent/examples/extensions/plan-mode/index.ts b/packages/coding-agent/examples/extensions/plan-mode/index.ts index bbeb7ab13..8d718b613 100644 --- a/packages/coding-agent/examples/extensions/plan-mode/index.ts +++ b/packages/coding-agent/examples/extensions/plan-mode/index.ts @@ -16,7 +16,7 @@ import type { AgentMessage } from "@earendil-works/pi-agent-core"; import type { AssistantMessage, TextContent } from "@earendil-works/pi-ai"; import type { ExtensionAPI, ExtensionContext } from "@earendil-works/pi-coding-agent"; import { Key } from "@earendil-works/pi-tui"; -import { extractTodoItems, isSafeCommand, markCompletedSteps, type TodoItem } from "./utils.ts"; +import { allStepsComplete, extractTodoItems, isSafeCommand, markCompletedSteps, type TodoItem } from "./utils.ts"; // Tools const PLAN_MODE_TOOLS = ["read", "bash", "grep", "find", "ls", "questionnaire"]; @@ -36,11 +36,16 @@ function isAssistantMessage(m: AgentMessage): m is AssistantMessage { return m.role === "assistant" && Array.isArray(m.content); } -// Extract text content from an assistant message +// Extract text content from an assistant message. +// Includes thinking blocks: with reasoning-max models the [DONE:n] tags and +// plan drafts usually land in thinking, not the visible text. function getTextContent(message: AssistantMessage): string { return message.content - .filter((block): block is TextContent => block.type === "text") - .map((block) => block.text) + .map((block) => { + if (block.type === "text") return block.text; + if (block.type === "thinking") return (block as { thinking?: string }).thinking ??

The `Translations` registry takes a list of `{ namespace, locale, messages, override? }` per contributor (one catalog per namespace and locale: the first by plugin name wins, reported; `override: true` wins); a missing key falls back down the locale's chain (`pt-BR`, `pt`) to the first catalog, reported once. `LocaleChoice` keeps one locale per principal on the server (the theme choice's store, now shared as one preference); a client follows it with `followActiveLanguage`, defaulting to `navigator.languages` on a page and the system locale in the terminal (`startTerminal`'s `locales`), matched against the catalogs, switched live. `useMessages(t)` (`/react`) and `TuiScope.messages(t)` (`/tui`) render in the host's language and re-render or redraw on a change; `startPage` sets `lang` and `dir` on the page (`followLanguage`, `/web`); `formatTime` and `formatNumber` use `Intl` in the language being rendered. The kit serves `Translations` on the server, workers, pages and terminals and `LocaleChoice` on the server; client errors gain `{ kind: "messages", report }`. +- Chord v2 gains telemetry across hosts (slice 9): `CHORD_TELEMETRY_SCHEMA` (root export) types every span, event and metric Chord records. With a host adapter (`createHost({ telemetry })`), calls (`chord.call`), methods (`chord.method`, local and remote), relays (`chord.relay`), holds (`chord.hold`), activations (`chord.activate`, ending `live`, `failed`, `parked` or `ended`, with `chord.retry` and `chord.park` events), natives' opens and closes, `load`, `reload` (a `chord.reload.fate` event per object), resolves (a worker start included), revocations, routine calls, job phases (`intent`, `run`, `finish`: a persisted run resumed in a new attempt or process stays under its stored carrier) and HTTP requests (`chord.http`: method, route pattern, status, never the path) are spans; failures carry a fixed category and the message cut at 500 characters, a cancel is no error; commits are `chord.commit { documents, ops, duration }` events of the span they ran under. `hold` and `call` carry the caller's trace carrier (`trace`, at most 8 keys, keys and values of at most 256 characters of printable ASCII, else the message fails the message schema and the link closes; the binary codec's kind byte flag `0x40`), relays forward their own span's, and the provider runs the method under it (an absent or unknown carrier: the adapter's root); a reference's carrier rides on its first hold only, a re-hold after a reconnect being a fresh root linked to it. A hold's `type` and its address's `kind` are bounded at 256 characters by the message schema, and span attributes a peer chose at 256 characters. `ctx.trace(name, attributes, fn)` runs `fn` in a child span with a child ctx. Host-wide metrics: `chord.link.bytes`, `chord.link.state_messages`, `chord.commit.duration`, `chord.calls.in_flight`, `chord.holds.active`, `chord.links.open`, `chord.park.duration`, `chord.backpressure.wait`. Without an adapter nothing is started, built or sent: a call over a link costs what it did before. `createHttp`, `startServer` and `startWorker` take a `telemetry` adapter (`createHttp` continues a W3C `traceparent` only from a request a contributed relay verified: an app's proxy must strip it from browsers). A host with an adapter counts the cost counters of its links' and root scopes' work on it also when the app passed a context without a span. The SQLite telemetry store keeps spans of one millisecond in the order they started. + ### Changed - Chord v2's HTTP component denies by default (slice 13): a request or plugin socket without a principal gets 401 before plugin code runs unless its route or socket is marked `public: true` (`{ handler, public: true }`; a `crossSite` route is public), and the `/chord` links endpoint refuses requests without a principal. diff --git a/packages/chord/docs/benchmarks.md b/packages/chord/docs/benchmarks.md index 4f5003322..749e26188 100644 --- a/packages/chord/docs/benchmarks.md +++ b/packages/chord/docs/benchmarks.md @@ -994,3 +994,43 @@ The diff depends on the reuse: with every row decoded anew, `diffRevisions` comp previous 100 by content and the watched commit took 885 µs; with unchanged rows the same objects it compares them by identity.

Single and chain output could also exceed the normal tool limit. This also adds a dedicated regression suite covering progress state, cancellation, process failures, output limits, cwd-based agent selection, and persisted tool-result error state. After this change: - queued, running, completed, failed, and aborted work stay distinct throughout the run; - interrupting the parent run preserves partial child results, stops queued work from starting, and escalates when a child ignores SIGTERM; - signal exits, spawn failures, provider errors, stderr, and assistant output remain visible instead of collapsing to `(no output)`; - failed subagents become failed tool results, so the parent model can react instead of treating them as successful calls; - single and chain results stay within the normal 50 KB / 2,000-line limit; - project agents are selected and confirmed from each task's actual working directory rather than the dispatcher's directory. ## Further potential improvements These are useful follow-ups, but they are separate product and storage decisions rather than part of the failure-handling fixes in this PR. <details> <summary>Potential follow-ups</summary> ### Keep persisted transcripts bounded Subagent tool results persist the full child message history in `details`, which can make parent session files large and slow to reload. A follow-up could compact that history or spill it to disk. ### Define an aggregate parallel-output budget Parallel mode still gives every task its own 50 KB budget. A follow-up could keep every task represented while enforcing one overall tool-result limit. ### Report child usage to the calling session Per-child token and cost usage is visible in result cards but is not added to the calling session's totals. ### Isolate malformed agent definitions One malformed YAML agent can still break discovery for every valid agent in the same directory. ### Limit subagent recursion A nesting limit would prevent accidental process and paid-request multiplication when subagents can invoke the subagent tool again. * https://github.com/earendil-works/pi/issues/8195 ### Add a configurable timeout Unattended runs would benefit from a generous opt-in timeout for children that never complete. </details> ## Related issues ### Spawn failures lose their diagnostics This directly addresses the reported case where a nonexistent child working directory produces `(no output)` instead of the actual spawn error. The regression suite includes that same reproduction. * https://github.com/earendil-works/pi/issues/8129 ### Persisted child history can bloat sessions This PR intentionally keeps full child history in tool-result details, so session compaction or spill-to-disk remains follow-up work rather than something fixed here. * https://github.com/earendil-works/pi/issues/7452 --- .../examples/extensions/subagent/README.md | 25 +- .../examples/extensions/subagent/index.ts | 559 +++++++++++----- .../test/fixtures/subagent-child.mjs | 80 +++ .../test/subagent-extension.test.ts | 621 ++++++++++++++++++ 4 files changed, 1103 insertions(+), 182 deletions(-) create mode 100644 packages/coding-agent/test/fixtures/subagent-child.mjs create mode 100644 packages/coding-agent/test/subagent-extension.test.ts diff --git a/packages/coding-agent/examples/extensions/subagent/README.md b/packages/coding-agent/examples/extensions/subagent/README.md index da74f3266..95d7ebe2a 100644 --- a/packages/coding-agent/examples/extensions/subagent/README.md +++ b/packages/coding-agent/examples/extensions/subagent/README.md @@ -8,7 +8,7 @@ Delegate tasks to specialized subagents with isolated context windows. - **Streaming output**: See tool calls and progress as they happen - **Parallel streaming**: All parallel tasks stream updates simultaneously - **Markdown rendering**: Final output rendered with proper formatting (expanded view) -- **Usage tracking**: Shows turns, tokens, cost, and context usage per agent +- **Usage display**: Shows turns, tokens, cost, and context usage inside each subagent result - **Abort support**: Ctrl+C propagates to kill subagent processes ## Structure @@ -62,7 +62,7 @@ This tool executes a separate `pi` subprocess with a delegated system prompt and To enable project-local agents, pass `agentScope: "both"` (or `"project"`).

Chord runs it before the object goes live and again inside the commit step of every commit of the object that writes the table, publishing only the diff in that commit's batch; a commit writing no table with a live query runs nothing (`chord.query.runs` counts the runs). Only the object's own tables; the limit is required (`invalid/args` at declaration). A run that fails (a row the code cannot read) is a failed member, reported once as the new `HostError` `query_failed { object, table, error }`, and heals at the next good run. A live query is no native, so an object showing table rows live swaps on reload instead of restarting, as reading them in `self.open` made it. Each touching commit runs the query once (100 rows: about 60 µs, 80 µs watched): not for tables written hundreds of times a second. - Chord v2 gains messages and languages in the app kit (design §23): `defineMessages(namespace, { en: {...}, de: {...} })` returns a typed `t(key, ...args)` (the first catalog types the others: a missing key, an unknown one or a wrong argument is a type error; values are strings or functions), `t.message(key, ...args)` builds a message as data (`MessageData`, `{ namespace, key, params }`, for state members typed with `MessageSchema`), `t.render(message)` renders one (a foreign namespace or an unknown key from a link shows the key), `t.translations` lists its catalogs, and `MessagesOf` types a translation. The `Translations` registry takes a list of `{ namespace, locale, messages, override? }` per contributor (one catalog per namespace and locale: the first by plugin name wins, reported; `override: true` wins); a missing key falls back down the locale's chain (`pt-BR`, `pt`) to the first catalog, reported once. `LocaleChoice` keeps one locale per principal on the server (the theme choice's store, now shared as one preference); a client follows it with `followActiveLanguage`, defaulting to `navigator.languages` on a page and the system locale in the terminal (`startTerminal`'s `locales`), matched against the catalogs, switched live. `useMessages(t)` (`/react`) and `TuiScope.messages(t)` (`/tui`) render in the host's language and re-render or redraw on a change; `startPage` sets `lang` and `dir` on the page (`followLanguage`, `/web`); `formatTime` and `formatNumber` use `Intl` in the language being rendered. The kit serves `Translations` on the server, workers, pages and terminals and `LocaleChoice` on the server; client errors gain `{ kind: "messages", report }`. -- Chord v2 gains telemetry across hosts (slice 9): `CHORD_TELEMETRY_SCHEMA` (root export) types every span, event and metric Chord records.

A hold's `type` and its address's `kind` are bounded at 256 characters by the message schema, and span attributes a peer chose at 256 characters. `ctx.trace(name, attributes, fn)` runs `fn` in a child span with a child ctx. Host-wide metrics: `chord.link.bytes`, `chord.link.state_messages`, `chord.commit.duration`, `chord.calls.in_flight`, `chord.holds.active`, `chord.links.open`, `chord.park.duration`, `chord.backpressure.wait`. Without an adapter nothing is started, built or sent: a call over a link costs what it did before. `createHttp`, `startServer` and `startWorker` take a `telemetry` adapter (`createHttp` continues a W3C `traceparent` only from a request a contributed relay verified: an app's proxy must strip it from browsers).

A hold's `type` and its address's `kind` are bounded at 256 characters by the message schema, and span attributes a peer chose at 256 characters. `ctx.trace(name, attributes, fn)` runs `fn` in a child span with a child ctx. Host-wide metrics: `chord.link.bytes`, `chord.link.state_messages`, `chord.commit.duration`, `chord.calls.in_flight`, `chord.holds.active`, `chord.links.open`, `chord.park.duration`, `chord.backpressure.wait`. Without an adapter nothing is started, built or sent: a call over a link costs what it did before. `createHttp`, `startServer` and `startWorker` take a `telemetry` adapter (`createHttp` continues a W3C `traceparent` only from a request a contributed relay verified: an app's proxy must strip it from browsers). A host with an adapter counts the cost counters of its links' and root scopes' work on it also when the app passed a context without a span. The SQLite telemetry store keeps spans of one microsecond in the order they started. +- Chord v2's telemetry closes four gaps found writing the tutorial: `chord.commit` counts the table rows a commit's writes changed (`rows`; a commit writing only rows no longer reads `documents=0 ops=0`); every span Chord starts, `ctx.trace`'s too, carries `chord.host`, the host's address key or `client` without an address (`Host` gains `address`); the SQLite telemetry store keeps span times in whole microseconds from pi-telemetry's `telemetryNow` (store version 2: a recorder migrates a version 1 file in place, its rows kept); and `openTelemetryStore(path)` (new subpath `@earendil-works/chord/telemetry-sqlite/node`) reads a store file read-only, implementing `TelemetryStore` only, refusing a file without a store or with one of another version. `openNodeSqliteDatabase` takes `mode: "read-only"`. +- Chord v2's telemetry is stored in one place, the server (decisions "Telemetry from browser pages", "The server is the one place telemetry is stored", "Who a span was for"). Pages and workers record in memory with Chord's `TelemetryRecorder` (the SQLite store's own recorder too) and send finished spans in batches over their link to the server's `PageTelemetry` and `WorkerTelemetry` (`ingest(batch)`), which the app kit serves when `startServer` has a telemetry store; the store gains `ingest` (never replacing a stored span). `startPage({ telemetry: true })` records the page and sends its spans every 3 s and when hidden; the server checks a page's batch strictly (at most 100 spans, every field bounded, ids printable ASCII, no control characters), keeps only spans under the page's own ids (`browser::`), caps them at 1,200 per page and minute, marks them `chord.host: browser` and stamps them with the principal of their link. A worker sends its spans and metrics every second, stamped with its host. `host.root(fn, ctx, { trace: { name, attributes } })` runs `fn` in a new root span (a click). Method and call spans record whom they were for: `chord.principal` (the principal key) by default, or what the host's new `principalAttributes` hook returns (`createHost`, `startServer`, `startWorker`). `ServeOptions.untraced` serves a type whose calls start no method span. `Host` gains `incarnation` and `principalAttributes`. ### Changed diff --git a/packages/chord/docs/design.md b/packages/chord/docs/design.md index f3c165e54..a28987f01 100644 --- a/packages/chord/docs/design.md +++ b/packages/chord/docs/design.md @@ -2769,7 +2769,9 @@ Chord reports traces, events and metrics through `@earendil-works/pi-telemetry`; `chord.open` (under the activation), `chord.close` (a root), `chord.load`, `chord.reload` (a `chord.reload.fate` event per object), `chord.resolve`, `chord.revoke` (recorded after the synchronous revocation, its `count`), `chord.routine` (a root per call), `chord.job` (`intent` under the starter, `run` and `finish` under the start's - carrier), `chord.http`.

The same object is the store's read interface, TelemetryStore (below).

    Step 1 opened the store before the server (chapter I), and startTodo gives it to startServer, which passes it to the -server's host and its HTTP component:

    +one batch a second, one row per span with its events and links inline and its start and end in microseconds (a +monotonic clock anchored to the wall clock, so spans of one process keep their order and spacing); metrics are summed +per series and 10 seconds; rows older than seven days are deleted in the same batch, and when 10,000 spans wait, new +ones are dropped and counted. Recording never runs SQL. The same object is the store's read interface, +TelemetryStore (below).

    Step 1 opened the store before the server (chapter I), and startTodo gives it to startServer:

    The kit carries no spans between processes: each process records to the adapter it was given (slice 9, §5). So each

+the server once a second, over the link it already has; nothing tells a worker where the file is, and the worker's
+entry has no telemetry of its own to set up:
    
 
-
    const telemetry = await openTelemetry(process.env.TODO_TELEMETRY!);
-startWorker({ api: API, kinds: KINDS, telemetry: telemetry.store, onError: (error) => console.error("list:", error) });
    
-
    One file for every process is the app's choice. SQLite in WAL mode lets several processes write it, each waiting for
-the others' locks (up to 5 seconds), and every span id is global, so rows of different processes never collide. An app
-with a collector would give each process an adapter that exports there instead; nothing else changes.
    
-
    One trace across three hosts
    
-
    A page in a browser cannot record yet: startPage takes no telemetry adapter. Step 11 makes the page itself, as Ada's
-client was made in chapter VII: a client host of this process with a recorder of its own on the same file, signed in
-with the owner's cookie from step 1. A click is one span of the page, and the call runs under it:
    
-
-
    const pageTelemetry = await openTelemetry(telemetryFile(dataDir));
-const page = createHost<TodoPrincipal>({
-	telemetry: pageTelemetry.store,
-	onError: (error) => console.error("page:", error.kind),
-});
-await page.load([], context);
-const pageSocket = new WebSocket(`${url.replace(/^http/, "ws")}/chord`, { headers: { cookie } });
-page.connect(webSocketLink(pageSocket as unknown as WebSocketLike), { principal: { kind: "server" } }, context);
-const pageTodos = await page.get(Todos, { list: "groceries" }, context);
-const click = (text: string) =>
-	pageTelemetry.store.startSpan({ name: "page.add" }, (span) => pageTodos.add(text, withTelemetry(span, context)));
-await click("honey");
-await click(" ").catch(() => "refused");
    
-
    startSpan runs the callback in a new root span; withTelemetry(span, context) makes it the context's span, so the
-call of add starts its chord.call under it and puts that span's carrier in the call's header. Each recorder writes
-once a second, so the step reads the store until the worker's spans are there, takes the older of the two traces whose
-first span is page.add and prints it with pi-telemetry's renderTrace (main.ts masks the lengths of time, which
-differ at every run):

-       chord.relay type="todo.todos" member="#0" upstream.kind="list" outcome="ok"

    Three processes recorded these six spans. The page recorded page.add and chord.call, the consumer's call until its
-reply. The server recorded chord.relay: it forwarded the call to the list's worker without knowing member names
-(#0 is the method's index). The worker recorded the rest: chord.method for the owner's Todos view, then the
-view's call of the store, which is a method span too, by worker, because the store acts as its host (chapter II).
-The commit is an event on the span its transaction ran under, and the renderer prints a span's events before its

    A page records when the app asks it to, in its web entry:
    
+
+
    	// The page records its clicks and the calls under them, and sends them to the server every few seconds.
+	telemetry: true,
    
+
    The page keeps its finished spans in memory and sends them every three seconds, and at once when it is hidden (a tab
+switched away may not come back). Both send to an object the kit serves on the server, WorkerTelemetry and
+PageTelemetry, whose ingest(batch) hands the spans to the store; its calls record no span of their own, or every
+batch would write a span about itself. A worker is the server's own child: its batches are written as they are,
+marked with its host. A page is anyone's: sign-in and the link's limits apply as for any call, and the server checks
+everything (next section).
    
+
    One trace from the browser
    
+
    The lists plugin's panel starts a trace where Ada's click starts: in its form's submit, a root span of the page's host
+with the call under it:
    
+
+
    		// The click is a trace of its own: a root span of the page, the call to the list's worker under it.
+		const trace = { name: "page.add", attributes: { chars: text.length } };
+		void host.root((ctx) => todos.add(text, ctx), context, { trace }).catch(() => {});
    
+
    host.root(fn, context, { trace }) runs fn in a new root span of the host's adapter, ctx.telemetry that span, so
+the call of add starts its chord.call under it and puts that span's carrier in the call's header (useHost gives a
+component its page's host). Without a recording adapter it starts nothing. screenshots.ts signs the owner in to the
+page in Chromium, types honey and submits, then submits again with nothing typed; it reads the store until the
+worker's spans of both clicks are there and prints honey's trace with pi-telemetry's renderTrace (ids and lengths of
+time masked, which differ at every run):

    Three processes recorded these six spans, and the server wrote them all. Each span says which host recorded it:
+chord.host is the host's address key (server, list|groceries), and browser for what a page sent. The page
+recorded page.add and chord.call, the consumer's call until its reply. The server recorded chord.relay: it
+forwarded the call to the list's worker without knowing member names (#0 is the method's index). The worker recorded
+the rest: chord.method for the owner's Todos view, then the view's call of the store, which is a method span too,
+by worker, because the store acts as its host (chapter II). The commit is an event on the span its transaction ran
+under, and the renderer prints a span's events before its children. It counts the documents it changed, their ops and
+the table rows its writes changed: the store keeps todos in a table, so one row and no documents. chord.principal
+says whom a span was for (below).

    Figure 5. One click, one trace: each process starts its spans with its own adapter, the carrier in each call's header names the parent span on the other side, and the page and the worker send their spans to the server, which writes them.
    
 
    The carrier is a field of the call and hold headers, at most 8 keys of at most 256 characters each. The receiver
 reads it with its own adapter; an absent or malformed one gives a new root, never an error. With the NOOP adapter
 nothing is injected and no span starts: a span site costs one check (§30).
    
+
    What a page sends, the server treats as untrusted. A batch is checked by its schema: at most 100 spans, every field
+bounded (names 128 characters, 32 attributes of at most 256 characters, 16 events, 8 links, a 500-character error
+message), ids printable ASCII and no control characters anywhere; a batch outside it is refused whole. A page's span
+ids are browser:<its host's incarnation>:<n>, and the server takes only spans whose id, trace and parent carry the
+calling page's own prefix: a page can neither write into another sender's trace nor pose as a server span, and the
+store never replaces a stored span. A page may send 1,200 spans a minute; past that they are dropped and counted in
+ingest's answer. The server marks each span chord.host: browser and stamps it with the principal of the link it came
+over: what a page says about itself counts for nothing.
    
 
    The trace holds the click and nothing else. Work that serves many requests is its own trace, linked to the span that
 first needed it: a worker's start (chord.resolve), an object's activation (chord.activate). A link is a reference to
 a span of another trace; the renderer prints it and never follows it.
    
 
    Trap: a trace starts where a span starts

    The page took its reference to Todos before the click, under BACKGROUND_CONTEXT, and that hold is in no trace of

    +

    Whom a span was for

    +

    Method and call spans record whom they were for: by default chord.principal, the principal's key (its canonical +JSON). An app may record other attributes instead, through a hook each host takes (principalAttributes): the todo +app's records a short key and, for a user, the name she signed in with:

    + +
    export function principalAttributes(principal: TodoPrincipal): Readonly<Record<string, string>> {
+	let attributes = recorded.get(principal);
+	if (attributes === undefined) {
+		attributes =
+			principal.kind === "user"
+				? { "chord.principal": `user:${principal.id}`, "user.name": principal.name }
+				: { "chord.principal": principal.kind === "worker" ? `worker:${principal.list}` : principal.kind };
+		recorded.set(principal, attributes);
+	}
+	return attributes;
+}
    +

    Chord calls the hook for every span it records with a principal, so it must be synchronous and cheap; any caching is +the hook's own (here a WeakMap by principal: a link stamps one principal object on all its calls). startTodo gives +it to the server (principalAttributes beside telemetry) and the worker's entry to startWorker (above): each host +has its own, the same function. The server also stamps a page's spans with it, for the principal of the link the batch +came over: page.add above was the owner's. Only what the hook returns is recorded, never other app data, and the +attributes are for the owner's eyes: the store, like the viewer below, is the owner's.

    Reading

    The store is read through TelemetryStore, pi-telemetry's read interface modeled on Jaeger's: findTraces (complete traces, newest first, filtered by their first span's name, attributes, errors or a time window, paged by a cursor), getTrace(id) and findMetrics (a metric's rows, one per series and 10 seconds, with count, sum, min and max). -trace.ts is a script for a data directory, the app running or not:

A hold's `type` and its address's `kind` are bounded at 256 characters by the message schema, and span attributes a peer chose at 256 characters. `ctx.trace(name, attributes, fn)` runs `fn` in a child span with a child ctx. Host-wide metrics: `chord.link.bytes`, `chord.link.state_messages`, `chord.commit.duration`, `chord.calls.in_flight`, `chord.holds.active`, `chord.links.open`, `chord.park.duration`, `chord.backpressure.wait`. Without an adapter nothing is started, built or sent: a call over a link costs what it did before. `createHttp`, `startServer` and `startWorker` take a `telemetry` adapter (`createHttp` continues a W3C `traceparent` only from a request a contributed relay verified: an app's proxy must strip it from browsers).

A worker sends its spans and metrics every second, stamped with its host. `host.root(fn, ctx, { trace: { name, attributes } })` runs `fn` in a new root span (a click). Method and call spans record whom they were for: `chord.principal` (the principal key) by default, or what the host's new `principalAttributes` hook returns (`createHost`, `startServer`, `startWorker`). `ServeOptions.untraced` serves a type whose calls start no method span. `Host` gains `incarnation` and `principalAttributes`. +- Chord v2's telemetry is stored in one place, the server (decisions "Telemetry from browser pages", "The server is the one place telemetry is stored", "Who a span was for").

Chord cancels a released reference's calls, so the archive call rejected with "p2.sessions: released", shown as the composer toast over the owner-notice lane. The archive now holds a reference of its own until it is done, and the server runs its steps in a root of its own. The archive stopped the worker with Hosts.stop, which restarts it for its holders: the page's lingering conversation started a worker the archived session refused (resolve_failed, "Worker: Session is archived" notice). SessionWorkerControl.suspend stops it and leaves its holders suspended until a restore (retry) or their release; archive, a failed fork's archived copy and an archived session's index rebuild use it. --- apps/p2/docs/p2-notes.md | 6 +- apps/p2/plugins/search/server.ts | 2 +- apps/p2/plugins/sessions/SessionOptions.tsx | 15 ++++- apps/p2/plugins/sessions/server.ts | 18 +++-- apps/p2/src/hosts/session-workers.ts | 14 ++++ apps/p2/src/runtime/server.ts | 8 ++- apps/p2/test/p2/archive.test.ts | 74 +++++++++++++++++++++ apps/p2/test/p2/helpers.ts | 1 + apps/p2/test/p2/ui-mobile-fixes.test.ts | 25 +++++++ 9 files changed, 149 insertions(+), 14 deletions(-) create mode 100644 apps/p2/test/p2/archive.test.ts diff --git a/apps/p2/docs/p2-notes.md b/apps/p2/docs/p2-notes.md index 7bd5ee4ef..521e2992c 100644 --- a/apps/p2/docs/p2-notes.md +++ b/apps/p2/docs/p2-notes.md @@ -444,7 +444,9 @@ navigates to its view before awaiting the worker, so a failed first start also h Host `onError`, refused reloads and worker failures publish bounded, redacted owner notices (`LogNotices`), with Show logs and Dismiss.

charset=UTF-8 Content-Transfer-Encoding: 8bit Several places truncate text by UTF-16 code units with `slice()`. When the cut lands between the two halves of a surrogate pair (an emoji or other character outside the Basic Multilingual Plane), the result keeps a lone high or low surrogate. That is invalid UTF-16. Example: a grep match line with 499 ASCII characters followed by `😀` is cut at 500 units, so the output ends in `\uD83D... [truncated]`. The bundled providers strip lone surrogates before sending (`sanitizeSurrogates` in pi-ai), so the usual effect is a dropped character. But the broken text still reaches the session file, RPC and JSON clients (strict UTF-8 encoders such as Rust's serde_json reject lone surrogates), extensions, and custom providers. This adds `sliceHead(text, n)` and `sliceTail(text, n)` to `core/tools/truncate.ts`. They behave like `slice(0, n)` and `slice(-n)` but return one unit fewer when the cut would split a pair, and are used where truncated text reaches the model: - `truncateLine` (grep match lines), the case reported in #7121 - codemode `truncateOutput` head and tail, and its argument and error previews - compaction `truncateForSummary` (tool results sent to the summarizer) - MCP server summaries in the system prompt and stderr tails in connection errors The cost is two `charCodeAt` checks per truncation, and nothing on the untruncated path. The surrogate check follows the fix in #7122 by @IKEASven69, which @cristinaponcela reviewed in a follow-up branch. That PR was closed before merging. Not changed: TUI-only previews (renderers, visual truncation) and line-based slicing. pi-private's pi-durable codemode `output.ts` has the same head/tail slicing and needs a separate change there. **Testing** - New `test/truncate-surrogates.test.ts`: an emoji at the cut in `truncateLine` is dropped whole, an emoji ending exactly at the limit is kept, `sliceHead`/`sliceTail` never leave a lone surrogate for any length, and they match `slice` on text without surrogates. - `test/tools.test.ts`, compaction, MCP extension, and codemode tests pass. - `npm run check` passes. fixes #7121 This PR is AI-generated. --- packages/coding-agent/CHANGELOG.md | 1 + .../coding-agent/src/core/compaction/utils.ts | 3 +- .../coding-agent/src/core/tools/truncate.ts | 28 ++++++++++- .../src/extensions/codemode/execute.ts | 8 ++-- .../coding-agent/src/extensions/mcp/index.ts | 3 +- .../src/extensions/mcp/runtime.ts | 5 +- .../test/truncate-surrogates.test.ts | 47 +++++++++++++++++++ 7 files changed, 86 insertions(+), 9 deletions(-) create mode 100644 packages/coding-agent/test/truncate-surrogates.test.ts diff --git a/packages/coding-agent/CHANGELOG.md b/packages/coding-agent/CHANGELOG.md index 472e4fb5d..0bdab578b 100644 --- a/packages/coding-agent/CHANGELOG.md +++ b/packages/coding-agent/CHANGELOG.md @@ -27,6 +27,7 @@ - Fixed RPC mode cutting off shutdown cleanup, such as a pending MCP token refresh, when stdin closed and SIGTERM arrived together, which process managers like Paseo and systemd do.

When it finished, the selection jumped back to the current model, or to the top row with a search query, discarding any browsing done in the meantime.

The kit watches the bundle's inputs as base code. p2 creates its session workers with SessionWorkers.create and keeps the worker base's inputs as a dev restart baseline. --- apps/p2/src/hosts/server.ts | 14 +- apps/p2/src/hosts/session-workers.ts | 29 ++- packages/chord/CHANGELOG.md | 1 + packages/chord/docs/design.md | 41 +++- packages/chord/docs/http-workers/book.md | 2 +- packages/chord/docs/http-workers/index.html | 2 +- packages/chord/src/node/app/app.ts | 32 ++- packages/chord/src/node/surfaces/bundle.ts | 10 +- packages/chord/src/node/workers/README.md | 47 +++-- packages/chord/src/node/workers/base.ts | 196 ++++++++++++++++++ packages/chord/src/node/workers/workers.ts | 39 +++- packages/chord/test/bench/workers.ts | 2 +- .../chord/test/examples/41-workers/main.ts | 2 +- .../test/examples/42-worker-crash/main.ts | 2 +- .../chord/test/examples/43-rollout/main.ts | 2 +- packages/chord/test/node/app/app.test.ts | 30 ++- packages/chord/test/node/workers/base.test.ts | 179 ++++++++++++++++ packages/chord/test/node/workers/support.ts | 8 +- .../chord/test/node/workers/workers.test.ts | 63 +++++- 19 files changed, 627 insertions(+), 74 deletions(-) create mode 100644 packages/chord/src/node/workers/base.ts create mode 100644 packages/chord/test/node/workers/base.test.ts diff --git a/apps/p2/src/hosts/server.ts b/apps/p2/src/hosts/server.ts index 165bb3197..bb02da159 100644 --- a/apps/p2/src/hosts/server.ts +++ b/apps/p2/src/hosts/server.ts @@ -1,6 +1,6 @@ // Server host: HTTP + WebSocket accept, routes `session:` hosts to session workers, loads the server facets. import { randomUUID } from "node:crypto"; -import { mkdirSync } from "node:fs"; +import { mkdirSync, readFileSync } from "node:fs"; import { createServer, type IncomingMessage, type ServerResponse } from "node:http"; import { homedir } from "node:os"; import { join } from "node:path"; @@ -42,7 +42,7 @@ import { } from "./bundles.ts"; import { devControl } from "./dev.ts"; import { readDevCommand, sendDevCommand, serveDevChannel } from "./dev-channel.ts"; -import { LoadedModules, loadedModuleHashes, loadedPluginFiles } from "./dev-modules.ts"; +import { contentHash, LoadedModules, loadedModuleHashes, loadedPluginFiles } from "./dev-modules.ts"; import { createP2Plugins, listPlugins, PLUGINS_DIRECTORY, SERVER_PACKAGES, selectPlugins } from "./plugins.ts"; import { contentSecurityPolicy, @@ -174,7 +174,7 @@ export async function startServer(options: ServerOptions = {}): Promise<P2Server const address = http.address(); const actualPort = typeof address === "object" && address !== null ?

With `--max-old-space-size=256` it crashes in `Runtime_StringSplit` (OOM). - Files over about 512 MB fail with `Cannot create a string longer than 0x1fffffe8 characters`. Files over 2 GB fail with `ERR_FS_FILE_TOO_LARGE`. - Aborting only rejects the promise; the read keeps running in the background. ## Solution - `ReadOperations` gets a new optional `createReadStream(absolutePath, { signal })`, which returns an `AsyncIterable<Uint8Array>` (a Node `Readable` works). The default local operations open the file once, `fstat` the handle, and stream from it. Like `fs.readFile`, they stop a regular file at its size when opened: text appended during the read is not counted, and a file that keeps growing still finishes. A file that reports size 0 (such as `/proc` files) and other file types (FIFOs, devices) are read until EOF, as `fs.readFile` reads them. No existing member changed. - The text path decodes the chunks with a streaming UTF-8 `TextDecoder` (non-fatal, `ignoreBOM: true`). That matches `Buffer.toString("utf-8")`, including invalid bytes and a UTF-8 byte order mark kept as U+FEFF. - It counts every line but stores only the selected lines `truncateHead` can show. Storing stops once the stored lines are past `DEFAULT_MAX_LINES` or `DEFAULT_MAX_BYTES`, plus one more line, and the existing `truncateHead` runs on the stored lines. `totalLines`/`totalBytes` are then patched from the counts, as grep and find do on main. - The extra line is needed because `truncateHead` drops a trailing empty line. Example: 2001 short lines, then an empty line, then more text. If storing stopped at the empty line, the stored text would end in `\n`. `truncateHead` would count 2000 lines and report "not truncated", but the full text is truncated by lines. - A line over 50KB is never stored whole; only its size is tracked. A first line of 1 GB therefore still gives today's `[Line 1 is ..., exceeds 50.0KB limit ...]` notice. - Abort: the signal is passed to the stream, and the loop also checks it between chunks. Leaving the loop closes the stream. - The whole-file path stays unchanged for custom operations without `createReadStream`, and for fractional `offset`/`limit` or negative `limit`. Array slicing defines what those odd ranges select; for example, `limit: -1` selects all lines but the last. - Images are unchanged. Output is the same as main's, byte for byte, including line counts, notices, details (including key order) and errors. A file appended to during the read gives the same output too: both read a regular file up to its size when opened. Out of scope: the trailing-newline off-by-one in line counts from #7329 is kept as is. ## Testing - `test/read-streaming.test.ts` keeps a copy of the old text algorithm as the reference. It compares the streaming path against it on text, details and error messages, with chunks of 1 and 4096 bytes and offsets and limits around the boundaries. The cases are: empty file, trailing newline or not, CRLF, multi-byte characters and a UTF-8 BOM, 2001 lines, and a first line over 50KB. There are also edge cases where the line or byte cap falls exactly on an empty line, and the 50KB + trailing newline case that `truncateHead` reports as `truncatedBy: "lines"`. Further tests: - details key order - multi-byte characters split across chunks, and invalid UTF-8 - the `readFile` fallback, including fractional and negative ranges - local files through the default stream, including EISDIR - abort: the stream is closed and no more chunks are pulled - a local file appended to mid-read (a decode hook in the test appends after the first chunk): `limit: 1` still says `[1 more lines ...]`. This test fails with an unbounded `fs.createReadStream`. - bounded memory: a child process with `--max-old-space-size=64` reads a 200 MB single line, generated in memory as 64 KB chunks from a custom `createReadStream`, and must print the size notice. It takes about 0.8 s and uses 17 MB of heap. If over-long lines are stored whole, it runs out of memory. 64 KB chunks matter here: V8 keeps decoded strings of 1 MB outside the heap limit, so with 1 MB chunks the test would not catch that regression. - With main's `read.ts`, 5 of the 8 tests fail: matrix, key order, chunked decoding, bounded memory and abort. The fallback, local-file and append tests pass on main because they check behavior that did not change. Removing the one-line-past-the-cap rule, or the trailing-empty-line adjustment of `totalLines`, makes the matrix fail. - `test/tools.test.ts`, `read-line-range-display`, `tool-execution-component`, `block-images` and `image-resize-callers` pass. `npm run check` is clean. Measured with an ad-hoc script on a 200 MB log.

A background process that inherited those pipes and keeps writing keeps the tool waiting after the shell exited. When the timeout then hits, the tool reported only `Command timed out after N seconds`. Example, timeout 3s: ```bash bash -c 'while true; do echo tick; sleep 0.05; done' & sleep 1; echo boom >&2; exit 1 ``` The shell exits with code 1 after ~1s. The tool still times out at the deadline, because the loop is still writing to its output. Both facts are true: the command failed with code 1, and something it started was still running at the timeout. The old message dropped the first, so the model read a failed command as a slow one and retried with a longer timeout, which never helps here. ## Fix The timeout stays a timeout, since the tool did hit its deadline while background processes were still writing. When the shell had already exited before the deadline, the message now also says so: ``` Command timed out after 3 seconds. The shell exited with code 1 after 1.1 seconds, but background processes it started kept writing output until the timeout. ``` A shell still running at the deadline keeps the plain `Command timed out after N seconds`. The local backend throws a module-private `ShellTimeoutError` with the message `timeout:<seconds>` as before, so custom `BashOperations` that throw `timeout:N` are unaffected. ## Behavior per platform - Linux and macOS: the shell runs in its own process group (`detached: true`). At the deadline `kill(-pgid)` still reaches the background processes after the shell exited, the pipes close, and the tool returns at the deadline. Tested on Linux; macOS uses the same mechanism and matches the macOS repros in the issue. - Windows: still not fully solved. At the deadline `taskkill /T /PID <shell>` fails with `process not found`, because the shell pid is gone. Walking parent pids does not help: Git's `bin\bash.exe` is a launcher for `usr\bin\bash.exe`, and the orphaned loop's parent is that already-exited inner bash, not the pid pi holds. The tool keeps reading until the output pauses for 100ms. Measured with Git Bash: the message is now correct, but the tool returned after 14s instead of 3s; with a loop that never pauses it never returns. This PR only fixes the reporting. ## Same pattern elsewhere - `packages/durable/src/env/node.ts` (`NodeExecutionEnv.exec`): same code, same false `timeout:N` after the shell exited. Same Windows limitation. - `packages/coding-agent/src/core/exec.ts` (`pi.exec` for extensions): the timeout sends SIGTERM/SIGKILL to the direct child only, no process group. A descendant that keeps writing keeps the call waiting past the timeout on every platform, and the result has `killed: true` even when the child had already exited with its own code. - `packages/coding-agent/src/core/package-manager.ts` (capture commands for git/npm): waits for `close` and kills only the direct child on timeout, so a descendant holding the pipes makes the timeout ineffective on every platform, even when the descendant writes nothing. - `packages/mcp/src/transports/stdio.ts`: on Windows, closing a server that already exited skips taskkill, so children holding its pipes survive. The code documents this as a known limitation. Possible follow-up for Windows and the cases above: once the deadline passed, stop waiting for the pipes (destroy our ends). On Windows this also ends most writers, which die from a broken pipe (tested with Git Bash). ## Tests - `test/suite/regressions/11613-bash-timeout-after-shell-exit.test.ts` (Unix only; it would hang on Windows for the reason above): background writer after the shell exits with code 3, and a shell still running at the deadline. The first case fails without the fix. - Checked manually on Windows 11 with Git Bash through the built bundle: both messages are as above. - `npm run check`, `test/tools.test.ts`, the #5303 and #5208 regressions, `bash-close-hang-windows`, `powershell-tool`, `shell-kill-process-tree`.

If pi exits after the token request went out but before the new token is written, the provider has already spent the old single-use refresh token and auth.json keeps only that one. The next request fails with `invalid_grant`. Trace: `pi --mode rpc` starts, `get_state` is answered, catalog refresh sends the token request, the client sends SIGTERM (or closes stdin), `shutdown()` runs `runtimeHost.dispose()`, which does not know about the refresh, and the process exits. Same for print and interactive mode, and for a prompt-time refresh cut off by an exit. ## Fix - `RuntimeCredentials.modify()` tracks every pending modification (same idiom as the MCP `track()` / `McpAuthProvider.settled()`). - `RuntimeCredentials.settled()` / `ModelRuntime.settleCredentialWrites()` wait for them. - `AgentSessionRuntime.dispose()` waits for them. All modes exit through `dispose()`. No extra timeout: the OAuth refresh (15 s) and the auth.json lock wait (30 s) are already bounded, and a second signal still exits at once. Not changed: the catalog refresh still refreshes expired OAuth credentials, also for providers whose catalog does not use them (the pi.dev catalog for `openai`, `anthropic`, ...). Skipping that would need a per-provider "catalog needs auth" signal in pi-ai; it is optional now that exits wait. `docs/rpc.md` now says that pi waits for pending work before exiting. ## Testing - `test/runtime-credentials.test.ts`: `settled()` waits until a pending modification is written, and resolves after a failed one. - `test/suite/regressions/11692-dispose-waits-for-oauth-refresh.test.ts`: `dispose()` waits until the token from a background catalog refresh is saved. Fails without the fix. - Real process: `pi --mode rpc` with an extension OAuth provider (expired credential, 400 ms refresh), SIGTERM about 100 ms after the token request started. Without the wait: 3 of 3 runs kept the spent refresh token. With the fix: 3 of 3 saved the new one (exit 143). Closing stdin instead of SIGTERM: new token saved, exit 0. - `npm run check`; `test/rpc*`, `test/print-mode`, `test/model-runtime*`, runtime and regression suites pass. --- packages/coding-agent/CHANGELOG.md | 1 + packages/coding-agent/docs/rpc.md | 2 +- .../src/core/agent-session-runtime.ts | 6 + .../coding-agent/src/core/model-runtime.ts | 8 ++ .../src/core/runtime-credentials.ts | 20 ++- .../test/runtime-credentials.test.ts | 36 ++++++ ...92-dispose-waits-for-oauth-refresh.test.ts | 117 ++++++++++++++++++ 7 files changed, 188 insertions(+), 2 deletions(-) create mode 100644 packages/coding-agent/test/suite/regressions/11692-dispose-waits-for-oauth-refresh.test.ts diff --git a/packages/coding-agent/CHANGELOG.md b/packages/coding-agent/CHANGELOG.md index b9b6ea383..e161043b0 100644 --- a/packages/coding-agent/CHANGELOG.md +++ b/packages/coding-agent/CHANGELOG.md @@ -30,6 +30,7 @@ - Fixed the find tool reporting the result limit when exactly `limit` files match, and `limit: 0` in find and ls returning every result or an empty listing; limits below 1 now mean 1 ([#7121](https://github.com/earendil-works/pi/issues/7121)) - Fixed grep match lines, codemode output, compaction summaries of tool results, and MCP error and server summaries cutting an emoji or other non-BMP character in half when truncating, which left an invalid lone surrogate in the text ([#7121](https://github.com/earendil-works/pi/issues/7121)) - Fixed the read tool loading whole files into memory, which ran out of memory on large files even with `offset`/`limit`; it now streams the file and keeps only the shown lines.

Roots may be `{ path, required }`: a required root's plugin failing at `load` rejects it with a `PluginError` after the load settled. Files named `<name>.<kind>.<ext>` (`contract.web.tsx`) are of that kind, refused in facets of another kind with the chain of imports named. Single-file plugins (`hello.server.ts` at a root's top, grouped by name, host packages only). `installPlugin({ git, ref } | { npm, version }, root, ctx)` installs plugins from git (a shallow clone of a branch, tag or commit; a repository of several plugins too) or npm; a package lists the plugin folders it provides in its `package.json` (`"chord": { "plugins": ["./notes", "plugins/*", "!plugins/draft"] }`), used by discovery and `installPlugin` (without it: one plugin when the package's top has facet files, else its subfolders with a `package.json`). `testPlugin(dir, { kind, modules, stubs, principal }, ctx)` builds a plugin as production does and loads it on an in-memory host beside stub facets, collecting its contributions to registries nobody serves and listing the contracts it waits for. Agents' guide: `docs/plugin-authoring.md`. - Chord v2 gains the app kit (slice 13, `@earendil-works/chord/app`): `startServer<P>({ name, dataDir?, root?, listen?, api, kinds, principal, workers?, files?, install?, onError }, ctx)` lays out the data directory (`server/store.sqlite`, `workers/<kind>/<address>/`, `plugins/`, `logs/`, `owner-token`; one server per data directory), creates the server's store and host, HTTP, one workers component per worker kind and the plugins component over the app's required root and the user's root, and loads the server's plugins with the kit's objects; `startWorker({ api, kinds, busy?, onError })` is a worker's entry (its directory and store, the link to the server first, its plugins). The start-data objects `AppInfo` and `WorkerInfo` serve process values to plugins. Sessions (`Sessions`: `issue`, `verify`, `revoke`, `list`; tokens kept as SHA-256 hashes, compared in constant time; persisted ones end after 400 days unused and their browser cookie is renewed daily while used, ephemeral ones live in memory, at most `limits.ephemeralSessions`) authenticate a signed `HttpOnly`, `SameSite=Strict` cookie or `Authorization: Bearer`; a one-time owner link per start (`app.ownerLink()`, the token in the URL's fragment, single use, 10 minutes), an owner token file (mode 0600, written atomically) and device pairing (`POST /_chord/pair`, owner approval, a poll returning the token once; bounded in all and per client address) sign the owner in. The data directory, its stores and secret files are made private (0700, 0600) at every start; the home directory, a file system's root and another user's directory are refused. `Files` per host: small and chunked writes at a stored offset, ranged reads, a watchable index, caps, at most `limits.uploads` uploads under way. `app.exportData(address, path, ctx)` and `app.importData(archive, address, ctx)` move the data a worker created (its store and files) as a tar without stopping anything: a running worker writes its own store at one consistent point, else the server reads it under the worker's process lock (import refusing an existing address, another app's archive, every path leaving the target, and archives past `limits.importBytes` or `limits.importEntries`). `app.applyChanges(ctx)` and `app.plugins.install(source, ctx)`. Optional plugins as exported facets: `defineUsers(profile)`, `inviteFacet()`, `ephemeralLoginFacet()`. - Chord v2 gains web and terminal surfaces (slice 11): `webSurface` and `tuiSurface` (`@earendil-works/chord/surfaces`) build a client kind's base bundle from the app's entry at start (content-hashed, served forever) and publish its plugins' facets as scripts that register themselves (`chordFacet("<plugin>", "<digest>", function (require, module, exports) {…})`) and one combined file, with `WebScripts` and `TuiScripts` showing the current set (a rollout step publishes without waiting for clients) and the page served through the app's own template (`PageAssets`, `pageScripts`). `startPage` (`@earendil-works/chord/web`) runs a page's client host: the connection loop (`keepConnected`: 250 ms doubling to 5 s, wakes, silent sockets, `canRetry`), plugins applied in place on a new set (a failed one keeps its old facet), a reload when the server's base bundle changed, and the active theme as CSS variables. React bindings (`@earendil-works/chord/react`): `HostProvider`, `useHold`, `useWatch`, `useRegistry`, `useRefState` (React is an optional peer dependency). The terminal: `startTerminal` (`@earendil-works/chord/tui/launcher`) signs in with a token, a token file or device pairing and runs the app's terminal code always in a sandbox (a child process on pipes with Node's permission model: no file system, terminal, processes, workers, network or SQLite; Node 26.5.1 or later), filtering its output, relaying its link and confirming its actions (copy, open a URL, attach a file the user names); `startTerminalRuntime` and `TuiScope` (`@earendil-works/chord/tui`) inside it. Themes: the `Themes` registry, `ThemeChoice` (one dark and one light pick per principal), `followActiveTheme`, `themeVariables`, `terminalColor`. `startServer` gains `web` and `tui`. Plugin builds scope `*.module.css` files per plugin and file. Ephemeral sessions end with their client's last link (after a minute). The HTTP component's links endpoint gains an `opened` hook. diff --git a/packages/chord/README.md b/packages/chord/README.md index 6f87b6db9..51a96d912 100644 --- a/packages/chord/README.md +++ b/packages/chord/README.md @@ -18,6 +18,7 @@ The design, the rule book for all of this, is [docs/design.md](docs/design.md). | `@earendil-works/chord` | Contracts (`local`, `remote`, `method`, the schema builders), errors (`ChordError`, `isChordError`), hosts and facets (`createHost`, `defineFacet`), documents (`defineState`), derives and natives (`constant`, `mapShared`), routines and jobs (`defineJob`), links (`memoryLinkPair`, `ipcLink`, `webSocketLink`), registries (`defineRegistry`), the store (`openStore`, `defineTable`, queries, export and import), and the client surfaces' shared part (`Themes`, `ThemeChoice`, `WebScripts`, `TuiScripts`, messages and languages: `defineMessages`, `Translations`, `LocaleChoice`, `formatTime`, `formatNumber`). | Node and browsers | | `@earendil-works/chord/http` | HTTP: a Web-standard `fetch` handler (`createHttp`) built from the routes, wraps and sockets plugins contribute to the registry `Http`, authenticators (`Authenticators`), responses as descriptions, a security baseline on by default, Chord's Node listener and `nodeRequest`, the links endpoint. | Node | | `@earendil-works/chord/workers` | Workers: `createWorkers` runs a forked worker per address of a host kind, started on demand and stopped when idle; `workerMain` is a worker's entry; `processLock`. | Node | +| `@earendil-works/chord/workers/child` | The worker's side alone: `workerMain` and `processLock`, without esbuild (a worker entry imports this). | Node | | `@earendil-works/chord/plugins` | Plugins: discovery, builds with esbuild (`buildFacet`), evaluation, the watcher, rollouts, `createPlugins`, `installPlugin`, `testPlugin`, `pluginFile`. | Node | | `@earendil-works/chord/plugins/runtime` | `createPluginRuntime`: loads built plugins without esbuild (a worker's side). | Node | | `@earendil-works/chord/app` | The app kit: `startServer`, `startWorker`, the start-data objects, sessions and the owner's sign-in, device pairing, files, export and import per address, optional plugins (users, invites, ephemeral login). | Node | @@ -36,7 +37,7 @@ The design, the rule book for all of this, is [docs/design.md](docs/design.md). | `@earendil-works/chord/sqlite/node` | `NodeSqliteDatabase`, `openNodeSqliteDatabase`, and `NodeSqliteDatabaseOptions`. | Node | | `@earendil-works/chord/sqlite/cloudflare` | `DurableObjectSqliteDatabase` and the structural `DurableObjectSqliteStorage` binding type. | Cloudflare Durable Objects | -`esbuild` (for `/plugins` and `/surfaces`), `ws` (for `/http` and `/tui/launcher`) and `react` (for `/react`) are optional peer dependencies, imported only there; `/app` uses all but `react`. +`esbuild` (for `/plugins`, `/surfaces` and `/workers`), `ws` (for `/http` and `/tui/launcher`) and `react` (for `/react`) are optional peer dependencies, imported only there; `/app` uses all but `react`. ## Quick start diff --git a/packages/chord/docs/design.md b/packages/chord/docs/design.md index e0d4f6bd3..77ea35e96 100644 --- a/packages/chord/docs/design.md +++ b/packages/chord/docs/design.md @@ -2397,13 +2397,20 @@ draining old holder without polling). installed; they change only through an install, which needs a restart anyway).

It showed "Only one model in scope" and kept the current model, because `_cycleScopedModel` returned early for any list with one entry. `_cycleAvailableModel` had the same early return, so it also failed when the active model was no longer available and one other model was. A second bug had the same cause. When the active model was not in the list, the code treated it as if it were at index 0, so cycling forward skipped the first scoped model. With `--models A,B` and another model active, Ctrl+P went to B. This change adds a small `getNextCycleIndex` helper that both functions now use: - When the active model is not in the list, cycling forward selects the first entry and cycling backward selects the last. - It returns `undefined` (the "Only one model…" message) only when the list is empty, or when its single entry is already the active model. **Testing** - Added a regression test to `test/suite/agent-session-model-extension.test.ts`. It covers a one-model scope, a repeated cycle once that model is active, and forward and backward cycling into a two-model scope from outside it. The test fails without the change ("expected undefined to be 'faux-2'") and passes with it. - `npm run check` passes. - Manual check: `pi --model anthropic/claude-sonnet-4-5 --models anthropic/claude-opus-4-5`, then Ctrl+P. - Before: "Only one model in scope". - After: "Switched to Claude Opus 4.5". - With `--models anthropic/claude-opus-4-5,anthropic/claude-haiku-4-5`, Ctrl+P now selects opus instead of haiku.

CI builds only the pushed head, so the tagged release commit is never built and pkg.earendil.com has no build of a release. Example: for v1.4.0, v1.3.0 and v1.2.0 the tagged commits have Build Binaries and Nix runs, but no CI run. Internal users want to install a release from pkg.earendil.com as soon as it is tagged, without waiting for the npm release. ## Change - `ci.yml` also runs for `v*.*.*` tags (the pattern `nix.yml` uses), so the tagged commit is built and packed. - `preview-packages.yml` also publishes passing CI runs of release tags: `POST /_/releases` keeps the packages for good under the tag (it never moves), then the `latest` ref moves to it. Pre-releases (`v1.2.3-rc.1`) are released without moving `latest`. - `scripts/preview-packages.mjs publish` decides what a push run publishes (the workflow passes the run's branch and conclusion), reading the GitHub API with `fetch` before anything is uploaded. A tag push's `head_branch` is the tag's name, and a branch or tag can carry its own copy of CI, so: - every push run must be for a commit on main, comparing against main's resolved SHA (a bare `main` in compare would resolve to a tag named `main`); - a release tag must match `^v\d+\.\d+\.\d+(-[0-9A-Za-z.]+)?$`, have passing CI (CI packs before its tests run), and point at the commit, dereferencing annotated tags, also nested; - other names publish nothing. This also closes an existing hole: a tag named `main` on an unreviewed commit could move the `main` ref. - A release happens after the uploads and before moving refs, so `latest` never points at a failed release. The job summary lists the release's install commands. - A passing push run whose CI artifact expired (3 days) fails with "re-run CI" instead of passing silently, so a release tag cannot go unreleased unnoticed. ## Before / after for a release | | Before | After | |---|---|---| | CI of the tagged commit | none | build, test, pack | | `pkg.earendil.com/@vX.Y.Z` | 404 | kept for good | | `…@` | 404 | kept for good | | `…@latest` | none | moves to each release | | npm, binaries, pi.dev, Nix `stable` | unchanged | unchanged | | main and PR previews | unchanged | unchanged | Tag CI runs trigger Publish Model Catalog and Nix, which skip them (`head_branch != main`). ## Before merging - [x] Deploy pkg.earendil.com with `POST /_/releases` (earendil-pkg `7955990`); until then a tag run fails at the release call and `latest` does not move. ## Recommended (not required by this PR) Add a ruleset restricting creation, update and deletion of `v*` tags to maintainers / the release process. The checks above already keep unreviewed code out (every push run must be for a commit on main), but anyone with write access can push a `v*` tag on any main commit. On pkg.earendil.com that release is kept for good, takes the version number (the real release then gets `409` there) and moves `latest`, with no approval gate like npm's `npm-publish` environment. Build Binaries (npm) and Nix (`stable`) also act on `v*` tags today. ## Checks `npm run check`; `node --test scripts/preview-packages.test.mjs` (10 tests, under 2s, against a fake server for pkg.earendil.com and the GitHub API with raw API responses). Each of these mutations fails a test: bare `main` in compare, wrong API field names, no on-main check, no tag target check, one-level tag dereference, `latest` for pre-releases, unanchored or loose tag pattern, no CI conclusion check, dropping `identical`. actionlint reports only the existing `queue:` complaint. --- .github/workflows/ci.yml | 5 +- .github/workflows/preview-packages.yml | 29 +++-- scripts/preview-packages.mjs | 84 ++++++++++++-- scripts/preview-packages.test.mjs | 145 +++++++++++++++++++++++-- 4 files changed, 239 insertions(+), 24 deletions(-) diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 71e526c62..745c41be0 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -3,6 +3,9 @@ name: CI on: push: branches: [main] + # The release commit is pushed together with the next commit, so a push to main never builds it; the tag run does, + # and preview-packages.yml releases its packages on pkg.earendil.com. + tags: ['v*.*.*'] pull_request: branches: [main] @@ -29,7 +32,7 @@ jobs: - name: Build run: npm run build - # Previews are published for main and PRs from branches of this repo only (see preview-packages.yml). + # Previews are published for main, release tags and PRs from branches of this repo only (see preview-packages.yml). - name: Pack preview packages if: github.event_name == 'push' || github.event.pull_request.head.repo.full_name == github.repository env: diff --git a/.github/workflows/preview-packages.yml b/.github/workflows/preview-packages.yml index 3b4121b79..61cfb67ef 100644 --- a/.github/workflows/preview-packages.yml +++ b/.github/workflows/preview-packages.yml @@ -1,6 +1,9 @@ -# Publishes the preview packages that CI packed for main and for PRs from branches of this repo to pkg.earendil.com, -# moving the `main` or `pr-` ref, and deletes a PR's ref when the PR closes.

Also fixes a required property set to undefined being rejected when its schema accepts undefined, as TypeBox allows. --- packages/ai/CHANGELOG.md | 1 + packages/ai/test/validation-probes.test.ts | 22 ++----- packages/schema/CHANGELOG.md | 10 +++ packages/schema/README.md | 37 ++++++++--- packages/schema/src/builders.ts | 40 ++++++++++++ packages/schema/src/checks.ts | 70 ++++++++++++++++----- packages/schema/src/coerce.ts | 36 ++++++++++- packages/schema/src/compiler.ts | 23 ++++--- packages/schema/src/explain.ts | 36 ++++++----- packages/schema/src/index.ts | 5 ++ packages/schema/src/typebox-static.ts | 16 ++++- packages/schema/src/validator.ts | 15 ++++- packages/schema/test/builders.test.ts | 59 +++++++++++++++++ packages/schema/test/coerce-typebox.test.ts | 45 +++++-------- packages/schema/test/coerce.test.ts | 42 +++++++++++++ packages/schema/test/equal.test.ts | 29 +++++++++ packages/schema/test/typebox-static.test.ts | 30 +++++++-- packages/schema/test/validator.test.ts | 63 +++++++++++++++++++ 18 files changed, 477 insertions(+), 102 deletions(-) create mode 100644 packages/schema/test/equal.test.ts diff --git a/packages/ai/CHANGELOG.md b/packages/ai/CHANGELOG.md index 369cb68f5..dc2654166 100644 --- a/packages/ai/CHANGELOG.md +++ b/packages/ai/CHANGELOG.md @@ -10,6 +10,7 @@ ### Fixed +- Fixed tool arguments for `Type.BigInt()` and `Type.Undefined()` parameters being rejected: they convert as TypeBox converted them (`"42"` and `42` to `42n`, `null` to `undefined`), now that pi-schema supports both types. `Type.Void()` still rejects every JSON argument. - Fixed OpenCode Go Claude Haiku 5.5 failing with a 400 (`Invalid signature in thinking block ... bound to a different conversation`) after the tool list, system prompt, or earlier history changed, which left the session failing on every retry.
