From 07c9e5b6fdeb9443fc7ab82f1452f4e2d3ea5934 Mon Sep 17 00:00:00 2001 From: Mario Zechner Date: Wed, 4 Nov 2026 23:28:14 +0000 Subject: [PATCH 01/39] feat(p2): tools declare who may call them and where, turn origin from the run's inputs, agents give their own tools - P2Tool: origin (any|owner) and scope (any|main|subagent) on the tool; the worker's Durable registry checks them before each call (guardTool), no tool checks itself. owner: location tools, reload_plugins, conversations, ports, MCP tools. main: subagent, rename_session, conversations, ports, reload_plugins. subagent: team. - originOf reads pi.live.run.inputs through tx.submission: the owner's only if every input of the run is. Agent-written inputs record the writing turn's origin: subagent tasks and one-shot prompts, team messages, reports (answerOrigin), peer messages. No peer origin any more. - Subagents and one-shot agents get their caller's tools (default all, tools narrows), except scope main; with codemode the script-only tools; subagents get team. One-shot agents keep codemode and agent. A send takes away what the caller can no longer give. --- apps/p2/docs/p2-notes.md | 79 ++++++---- apps/p2/docs/plugin-hooks.md | 5 +- apps/p2/plugins/agent/tool.ts | 43 +++--- apps/p2/plugins/agent/worker.ts | 5 +- apps/p2/plugins/conversations/contract.ts | 20 ++- apps/p2/plugins/conversations/server.ts | 15 +- apps/p2/plugins/conversations/worker.ts | 35 +++-- apps/p2/plugins/dev-tools/tool.ts | 23 ++- apps/p2/plugins/history/tools.ts | 3 - apps/p2/plugins/locations/tool.ts | 25 ++-- apps/p2/plugins/mcp/tools.ts | 16 +- apps/p2/plugins/ports/contract.ts | 12 +- apps/p2/plugins/ports/tool.ts | 26 ++-- apps/p2/plugins/ports/worker.ts | 5 +- apps/p2/plugins/sessions/worker.ts | 20 ++- apps/p2/plugins/subagents/contract.worker.ts | 145 ++++++++++++------- apps/p2/plugins/subagents/tools.ts | 133 +++++++++-------- apps/p2/plugins/subagents/worker.ts | 25 +++- apps/p2/src/api/v1/worker.ts | 1 + apps/p2/src/runtime/durable.ts | 24 ++- apps/p2/src/runtime/entries.ts | 20 ++- apps/p2/src/runtime/origin.ts | 118 ++++++++------- apps/p2/src/runtime/tool-access.ts | 56 +++++++ apps/p2/test/p2/agent.test.ts | 2 +- apps/p2/test/p2/conversations.test.ts | 11 +- apps/p2/test/p2/dev-tools.test.ts | 57 ++++---- apps/p2/test/p2/inputs.test.ts | 129 +++++++++-------- apps/p2/test/p2/locations.test.ts | 2 +- apps/p2/test/p2/ports.test.ts | 2 +- apps/p2/test/p2/subagent-team.test.ts | 8 + apps/p2/test/p2/subagents.test.ts | 79 +++++----- apps/p2/test/p2/tool-access.test.ts | 122 ++++++++++++++++ 32 files changed, 777 insertions(+), 489 deletions(-) create mode 100644 apps/p2/src/runtime/tool-access.ts create mode 100644 apps/p2/test/p2/tool-access.test.ts diff --git a/apps/p2/docs/p2-notes.md b/apps/p2/docs/p2-notes.md index 774f99fed..1a6397f0c 100644 --- a/apps/p2/docs/p2-notes.md +++ b/apps/p2/docs/p2-notes.md @@ -146,11 +146,9 @@ is printed or needed in a URL.

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.

Migration: drop `telemetry` from `startWorker` and the store's path from the worker's environment. -- Chord v2's `createWorkers` returns a promise and rejects when the worker base does not build (decision "Workers start from the base code the server booted with"): it bundles the worker kind's `entry` and the base code it imports once with esbuild (`--conditions` from `execArgv`; Node builtins and packages resolved under `node_modules` external, by their files; workspace packages linked into `node_modules` inlined; `import.meta.url` and `__dirname` naming each source file; an inline source map, forked with `--enable-source-maps`) into a private temporary directory removed at `close`, and forks every worker from that snapshot: an edit of the app's source while the server runs (an agent half way through a change) no longer reaches workers forked later, which kept failing to start until the edit was fixed; a server restart applies it. `workers.inputs` lists the files the base was built from; the app kit's `startServer` builds each worker kind's base before loading (a broken one rejects the start, everything closed) and marks `base` when one of those files changes (it marked only the entry). +- Chord v2's `createWorkers` returns a promise and rejects when the worker base does not build (decision "Workers start from the base code the server booted with"): it bundles the worker kind's `entry` and the base code it imports once with esbuild (`--conditions` from `execArgv`; Node builtins and packages resolved under `node_modules` external, by their files; workspace packages linked into `node_modules` inlined; `import.meta.url` and `__dirname` naming each source file; split at each dynamic `import()` esbuild can follow, so a lazily imported module and the packages it imports load only when the worker imports it; inline source maps, forked with `--enable-source-maps`) into a private temporary directory removed at `close`, and forks every worker from that snapshot: an edit of the app's source while the server runs (an agent half way through a change) no longer reaches workers forked later, which kept failing to start until the edit was fixed; a server restart applies it. `workers.inputs` lists the files the base was built from; the app kit's `startServer` builds each worker kind's base before loading (a broken one rejects the start, everything closed) and marks `base` when one of those files changes (it marked only the entry). ### Added -- Chord v2's Node components and client surfaces are exported: `@earendil-works/chord/http`, `/workers`, `/plugins`, `/plugins/runtime` and `/app`; `/surfaces` (the web and terminal surfaces' server side), `/web`, `/react`, `/tui` and `/tui/launcher`. +- Chord v2's Node components and client surfaces are exported: `@earendil-works/chord/http`, `/workers`, `/workers/child` (the worker's side, `workerMain` and `processLock`, without esbuild), `/plugins`, `/plugins/runtime` and `/app`; `/surfaces` (the web and terminal surfaces' server side), `/web`, `/react`, `/tui` and `/tui/launcher`. - Chord v2's plugins component gains the plugin model (slice 12): `createPlugins({ api: { name, versions } })` checks every import of the app's versioned API (`@acme/app/v3`, per-kind modules such as `@acme/app/v3/web`): an unlisted version, another kind's module, two versions in one facet and a direct import of Chord are build errors naming the file and line. Roots may be `{ path, required }`: a required root's plugin failing at `load` rejects it with a `PluginError` after the load settled. Files named `..` (`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

({ name, dataDir?, root?, listen?, api, kinds, principal, workers?, files?, install?, onError }, ctx)` lays out the data directory (`server/store.sqlite`, `workers//

/`, `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("", "", 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).

Fixing one fixes the other. - - related: same area or a similar symptom, but a different trigger or request. - - List at most 5 issues, best first. Never list the issue itself. -3. Pick exactly one category, using the category definitions: - - MCP, codemode/tool_search, and durable/new-harness issues always go to those categories, whatever the symptom. - - Otherwise pick the component that behaves wrongly, or that must change for a feature request, based on the described behavior. - - Something shown wrongly (layout, colors, flicker) is tui. Wrong information shown (wrong models listed, wrong cost) belongs to the subsystem owning that information. - - Specific beats general: compaction over agent-loop, tools over agent-loop, models over providers for metadata and selection, extensions over sdk when the API is used from an extension. - - Documentation issues go to the category of the documented subsystem. - - If torn between two, pick one, set confidence to low, and name the other as alternative. -4. Suggest a priority. The maintainer decides; your suggestion only orders the report. - - p0: must fix. Crashes, hangs, wedged or corrupted sessions, data loss, wrong billing, security problems, regressions in a release, or problems many users hit. Several independent reports of the same problem are a strong p0 signal. - - p1: nice to have. Real but minor bugs, small well-scoped features or extension API gaps with a concrete use case. - - none: won't fix. Requests to add a provider or model, bugs in third-party extensions or packages, upstream bugs (proxies, models.dev data, terminals), theoretical problems found by reading code or by an AI audit that nobody hit in practice, vague reports without environment or repro, already fixed, features that belong in an extension, spam, empty issues. - - When unsure between p1 and none for a concrete, well-written report, pick p1. -5. Call submit_triage exactly once. Do not write any other text. - -Signals are short factual tags a maintainer can scan. Use these when they apply, add others only if important: -"regression", "hit in practice", "theoretical", "repro steps", "no repro", "environment given", "AI-written", "third-party", "upstream", "maybe fixed", "wants to contribute", "spam", "empty", "duplicate cluster" (two or more other reports of the same problem). - -You see the issue as it was filed. Judge it on its content. Issues from new contributors are auto-closed by a bot, and `no-action` only means no maintainer picked the issue up; neither is a rejection. A new report of an earlier no-action issue is evidence the problem is real: judge the pair on their merits, and prefer the better-written report. Issues closed as completed are fixed; a new report of one may be a regression or already fixed. - -The summary is one plain sentence: what breaks or what is requested, and when. No judgment, no restating the title. diff --git a/scripts/issues/register.mjs b/scripts/issues/register.mjs deleted file mode 100644 index b98906b57..000000000 --- a/scripts/issues/register.mjs +++ /dev/null @@ -1,3 +0,0 @@ -import { register } from "node:module"; - -register("./source-hooks.mjs", import.meta.url); diff --git a/scripts/issues/run.sh b/scripts/issues/run.sh deleted file mode 100755 index 675d512be..000000000 --- a/scripts/issues/run.sh +++ /dev/null @@ -1,5 +0,0 @@ -#!/usr/bin/env bash -# Start the issue triage server.

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.

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 page's own `chord.*` attributes are dropped). 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 `TuiScope` gains `optimistic(read)`: the reader and `show(value, call)`, which shows `value` in place of the reader's until every call shown settled (React's `useOptimistic` for terminal UIs).

Optimistic UI

+

A user renames a session. The call goes from the tab through the server to the session's worker, which renames it and +reports the new title to the server's index of sessions, then answers. That round trip takes a moment, and the title +should change at once. React's useOptimistic shows a value while a transition runs, and Chord's references fit it:

+
// plugins/sessions/web.tsx
+function SessionName({ id }: { id: string }) {
+	const sessions = useHold(Sessions, {});                       // the server's index, which every list shows
+	const session = useHold(SessionTitle, { id });                // on the session's worker
+	const title = useWatch(sessions?.titles)?.[id] ?? "";
+	const [shown, showOptimistic] = useOptimistic(title);
+	const rename = (next: string) =>
+		startTransition(async () => {
+			showOptimistic(next);                                    // drawn at once
+			await session?.rename(next, BACKGROUND_CONTEXT);         // settles once the index has `next`
+		});
+	return <TitleField value={shown} onRename={rename} />;
+}
+

When the transition ends, React drops the optimistic value and draws title again. That is only right if title is +already the new name by then. Chord guarantees it: a call settles in the page only after every change its answering +host committed before answering is applied there, and so does every change a host that relays the answer committed +before it forwarded it. Here the worker's own changes travel before its answer, and the server sends its index change +for this tab before it forwards the worker's answer, even on a slow connection whose window of unacknowledged state is +full (design §3). Without that, the answer could overtake the index change and the old title flickered back.

+

What it does not cover:

+
    +
  • Changes committed after the answer: a method that starts work and returns before it lands (a void call, a job, a +routine) answers first; the optimistic value goes and the old one shows until the change arrives.
    • +
  • Changes on a host that neither answers nor relays the answer. A server method that calls a worker and then answers +the tab orders only the server's own changes before its answer; what the worker changed for the tab travels on its +own and may come later.
    • +
+

So the rule for a method that should feel instant: it awaits its own changes, the pushes to other hosts included (the +worker's rename awaits its report to the index), and keeps them on the host that answers or relays the answer.

+

A terminal UI does the same with its component scope: scope.optimistic(read) wraps a reader and returns it with +show(value, call), which shows value until the call settles (until every call shown, when they overlap):

+
const titles = scope.watch(sessions.titles);
+const [title, show] = scope.optimistic(() => titles()?.[id]);
+await show(next, session.rename(next, ctx));              // title() is `next` at once, the real one when it settles
+

test/examples/63-optimistic-answers.ts runs this with a stalled terminal client and prints what each redraw showed.

Devices upload and pull a session's commits through a remote, reading them from the Chord store's outbox and applying them with `applyBatch`. If two devices continue the same session, the one that uploads second forks to a new session. I took out the extra sequence indexes from the earlier version of this branch, since the Chord outbox already persists every commit, so this no longer touches storage. --------- Co-authored-by: Armin Ronacher --- apps/p2/tsconfig.json | 1 + packages/chord/CHANGELOG.md | 1 + packages/chord/README.md | 1 + packages/chord/package.json | 5 + packages/chord/src/sync/batch.ts | 139 ++++ packages/chord/src/sync/client.ts | 536 ++++++++++++ packages/chord/src/sync/files.ts | 52 ++ packages/chord/src/sync/filesystem.ts | 233 ++++++ packages/chord/src/sync/index.ts | 48 ++ packages/chord/src/sync/lines.ts | 54 ++ packages/chord/src/sync/remote.ts | 168 ++++ packages/chord/src/sync/state.ts | 47 ++ packages/chord/test/bench/sync-memory.ts | 169 ++++ packages/chord/test/bench/sync-worker.ts | 450 ++++++++++ packages/chord/test/sync/lines.test.ts | 146 ++++ packages/chord/test/sync/node-files.ts | 59 ++ packages/chord/test/sync/sync.test.ts | 814 +++++++++++++++++++ packages/coding-agent/examples/tsconfig.json | 3 + tsconfig.json | 1 + 19 files changed, 2927 insertions(+) create mode 100644 packages/chord/src/sync/batch.ts create mode 100644 packages/chord/src/sync/client.ts create mode 100644 packages/chord/src/sync/files.ts create mode 100644 packages/chord/src/sync/filesystem.ts create mode 100644 packages/chord/src/sync/index.ts create mode 100644 packages/chord/src/sync/lines.ts create mode 100644 packages/chord/src/sync/remote.ts create mode 100644 packages/chord/src/sync/state.ts create mode 100644 packages/chord/test/bench/sync-memory.ts create mode 100644 packages/chord/test/bench/sync-worker.ts create mode 100644 packages/chord/test/sync/lines.test.ts create mode 100644 packages/chord/test/sync/node-files.ts create mode 100644 packages/chord/test/sync/sync.test.ts diff --git a/apps/p2/tsconfig.json b/apps/p2/tsconfig.json index 5641cf3da..afc80b2a6 100644 --- a/apps/p2/tsconfig.json +++ b/apps/p2/tsconfig.json @@ -30,6 +30,7 @@ "@earendil-works/chord/react": ["../../packages/chord/src/react/index.ts"], "@earendil-works/chord/tui": ["../../packages/chord/src/tui/index.ts"], "@earendil-works/chord/tui/launcher": ["../../packages/chord/src/node/tui/index.ts"], + "@earendil-works/chord/sync": ["../../packages/chord/src/sync/index.ts"], "@earendil-works/pi-telemetry": ["../../packages/telemetry/src/index.ts"], "@earendil-works/pi-telemetry/testing": ["../../packages/telemetry/src/testing/index.ts"], "@earendil-works/pi-telemetry/render": ["../../packages/telemetry/src/render.ts"], diff --git a/packages/chord/CHANGELOG.md b/packages/chord/CHANGELOG.md index e3e8c0632..aa89bdc73 100644 --- a/packages/chord/CHANGELOG.md +++ b/packages/chord/CHANGELOG.md @@ -11,6 +11,7 @@ ### Added +- The sync layer (experimental): `@earendil-works/chord/sync` moves a store between devices through a remote, from the store's outbox (`openStore(backend, ctx, { outbox: true })`). Every device continues a store as its own: `uploadSession()` uploads the outbox commits after the last sequence the copy shares with the remote as one gzip batch into a slot the remote creates once per start sequence, trims the outbox through what the remote acknowledged, and reports a copy as `diverged` when another device's upload created that slot first, or `behind` when its head fell below what it had uploaded. A store whose outbox does not reach back to its first commit starts with an archive slot (`store.export()`). `pullSession()` catches a copy up through `applyBatch()`, resumes an interrupted pull, or restores into an empty backend (`importStore()` for an archive); `foldSession()` folds the history into a snapshot archive, keeping folded slots taken. `FlushScheduler` decides when to upload. `FileSystemSyncRemote`, a remote in a directory, and `FileSyncStateStore`, sync state in a directory, are for development and tests; they take their file operations as a `SyncFileSystem` (Pi Durable's environments fit it as they are). - Chord v2's Node components and client surfaces are exported: `@earendil-works/chord/http`, `/workers`, `/workers/child` (the worker's side, `workerMain` and `processLock`, without esbuild), `/plugins`, `/plugins/runtime` and `/app`; `/surfaces` (the web and terminal surfaces' server side), `/web`, `/react`, `/tui` and `/tui/launcher`. - Chord v2's plugins component gains the plugin model (slice 12): `createPlugins({ api: { name, versions } })` checks every import of the app's versioned API (`@acme/app/v3`, per-kind modules such as `@acme/app/v3/web`): an unlisted version, another kind's module, two versions in one facet and a direct import of Chord are build errors naming the file and line. Roots may be `{ path, required }`: a required root's plugin failing at `load` rejects it with a `PluginError` after the load settled. Files named `..` (`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

({ name, dataDir?, root?, listen?, api, kinds, principal, workers?, files?, install?, onError }, ctx)` lays out the data directory (`server/store.sqlite`, `workers//

/`, `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()`. diff --git a/packages/chord/README.md b/packages/chord/README.md index 51a96d912..9b27d475d 100644 --- a/packages/chord/README.md +++ b/packages/chord/README.md @@ -36,6 +36,7 @@ The design, the rule book for all of this, is [docs/design.md](docs/design.md). | `@earendil-works/chord/sqlite` | Portable `SqliteDatabase`, `SqliteExecutor`, and `SqliteValue`, atomic `applySqliteMigrations(database, migrations, { table })`, and `validateSqliteSchemaPrefix`.

Account sign-in is the default and takes the provider's browser method; when the provider has another method, it prints a hint to rerun with --no-browser. --no-browser skips the browser method and uses the other one, such as device code, asking only when there are several. --api-key saves an API key instead and cannot be combined with --no-browser. After logging in, it fetches the provider's model catalog, and for Radius it points the Radius MCP server in the global mcp.json at the login without asking. pi auth logout removes the stored credentials like /logout and succeeds when nothing is stored. For MCP servers that use provider credentials, pi mcp login and logout now refer to these commands instead of /login and /logout. /login shares the check for the Radius MCP server entry and the web URL helpers with the new command. --- packages/coding-agent/CHANGELOG.md | 1 + packages/coding-agent/docs/cli.md | 15 +- packages/coding-agent/src/cli/args.ts | 2 +- packages/coding-agent/src/cli/auth-command.ts | 28 +- packages/coding-agent/src/cli/auth-login.ts | 277 ++++++++++ packages/coding-agent/src/cli/auth-logout.ts | 72 +++ .../coding-agent/src/cli/auth-terminal.ts | 78 +++ .../src/core/provider-matching.ts | 11 + packages/coding-agent/src/core/radius-mcp.ts | 44 ++ .../coding-agent/src/extensions/mcp/cli.ts | 12 +- packages/coding-agent/src/main.ts | 47 ++ .../interactive/components/login-dialog.ts | 20 +- .../src/modes/interactive/interactive-mode.ts | 45 +- .../src/utils/terminal-question.ts | 29 ++ packages/coding-agent/src/utils/web-url.ts | 20 + packages/coding-agent/test/auth-login.test.ts | 481 ++++++++++++++++++ .../coding-agent/test/auth-logout.test.ts | 99 ++++ .../coding-agent/test/auth-terminal.test.ts | 63 +++ .../coding-agent/test/mcp-command.test.ts | 2 +- .../test/provider-matching.test.ts | 35 ++ .../test/terminal-question.test.ts | 79 +++ 21 files changed, 1392 insertions(+), 68 deletions(-) create mode 100644 packages/coding-agent/src/cli/auth-login.ts create mode 100644 packages/coding-agent/src/cli/auth-logout.ts create mode 100644 packages/coding-agent/src/cli/auth-terminal.ts create mode 100644 packages/coding-agent/src/core/provider-matching.ts create mode 100644 packages/coding-agent/src/core/radius-mcp.ts create mode 100644 packages/coding-agent/src/utils/terminal-question.ts create mode 100644 packages/coding-agent/src/utils/web-url.ts create mode 100644 packages/coding-agent/test/auth-login.test.ts create mode 100644 packages/coding-agent/test/auth-logout.test.ts create mode 100644 packages/coding-agent/test/auth-terminal.test.ts create mode 100644 packages/coding-agent/test/provider-matching.test.ts create mode 100644 packages/coding-agent/test/terminal-question.test.ts diff --git a/packages/coding-agent/CHANGELOG.md b/packages/coding-agent/CHANGELOG.md index de6bd9b0f..7a51caad1 100644 --- a/packages/coding-agent/CHANGELOG.md +++ b/packages/coding-agent/CHANGELOG.md @@ -11,6 +11,7 @@ - `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.

Migration: drop `telemetry` from `startWorker` and the store's path from the worker's environment. - Chord v2's `createWorkers` returns a promise and rejects when the worker base does not build (decision "Workers start from the base code the server booted with"): it bundles the worker kind's `entry` and the base code it imports once with esbuild (`--conditions` from `execArgv`; Node builtins and packages resolved under `node_modules` external, by their files; workspace packages linked into `node_modules` inlined; `import.meta.url` and `__dirname` naming each source file; split at each dynamic `import()` esbuild can follow, so a lazily imported module and the packages it imports load only when the worker imports it; inline source maps, forked with `--enable-source-maps`) into a private temporary directory removed at `close`, and forks every worker from that snapshot: an edit of the app's source while the server runs (an agent half way through a change) no longer reaches workers forked later, which kept failing to start until the edit was fixed; a server restart applies it. `workers.inputs` lists the files the base was built from; the app kit's `startServer` builds each worker kind's base before loading (a broken one rejects the start, everything closed) and marks `base` when one of those files changes (it marked only the entry). +- Chord v2's `host.reload` restarts every live object of a changed plugin; the pure swap in place is removed (decision "Reload restarts every affected object; old work finishes on old code"). `ReloadReport.objects` no longer has the kind `swapped`: a live object is `restarted`, or `parked { cause }` when its successor's recorded requests find a failure. Old work (the calls running at the commit and every call they cause through their `ctx`, and calls marked `old` over a trusted link) runs on the object's open old attempt; new calls wait at the gate for the new code. The old attempt is sealed once that work drained and its successor's requests are ready, bounded by the new host option `reloadDrainTimeout` (default 5 s, at most `closeTimeout`; the app kit's `timeouts.reloadDrainTimeout` reaches the server and every worker): a method still running then is cut `released` and reported `drain_timeout`. A wait of old work that its own old attempt blocks fails at once with `unavailable/reload_cycle`; a getter of old work for a version the new code dropped binds the open old attempt or fails at once. `call` gains `old` (binary flag `0x20`, the text codec's seventh element; a relay drops it from untrusted links; `PROTOCOL_VERSION` stays 1); `waiting` causes keep the reason `unavailable/version`. Consequences: a reference shows `loading` briefly after every reload of its object (it stayed bound across a swap); a value read right after `host.reload` resolves may still be the old code's; an in-memory job run ends `aborted { reload }` at every reload of its object (it finished on its old code across a swap); routines restart when the successor goes live. Migration: drop `swapped` from code reading the report; open a root inside a method with `withoutAbortSignal(ctx)`, not a fresh context, so its calls are old work; move work longer than `reloadDrainTimeout` into jobs. ### Added @@ -21,7 +22,7 @@ - Chord v2's root exports `invalid(reason, message, details?)` and the new `forbidden(message, details?)`, the `ChordError`s a plugin throws for arguments or params it refuses (`invalid/args`, `invalid/params`) and for a principal it refuses (`forbidden`); an app's API re-exports them, and the caller gets the same `{ code, reason }` as from Chord's own checks. - 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.

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. 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, rows, 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 microsecond in the order they started. diff --git a/packages/chord/docs/design.md b/packages/chord/docs/design.md index d4839b51d..8e6d835df 100644 --- a/packages/chord/docs/design.md +++ b/packages/chord/docs/design.md @@ -279,9 +279,9 @@ the app exits with its own code for its supervisor or reopens. | `readyTimeout` | an activation attempt's own steps (its wait for the previous instance's teardown included; paused while the attempt is parked on its dependencies, slice 7a); a getter's whole wait; how long a call made while its reference is loading waits (the park deadline) | 60 s | per `get`/`hold`/`registry`: `{ readyTimeout }` | The park deadline's per-type override is not built (only if a real case needs it).

[PATCH 31/39] feat(p2): Chord v2 cleanup pass p2 rewritten by the Chord v2 authoring rules (decision "App authoring rules confirmed by the p2 audit"), in four parts merged together: - core: session lifecycle (relocate, clone, fork, archive) and search rebuild are persisted jobs on a new server store; Sessions v6 with client-chosen ids and visible operations; Retry answers with the worker's real outcome; workers push branch, subagent and status state to the server; roots take the method's ctx. - services: models, envs, ports, login, mcp, logs, sharing and voice follow external state (self.follow, followNative) instead of copy loops; methods answer after their state commits; presence from host.references. - chat: chat mode, artifacts and prompt resources follow Durable and native state; shell commands are Chord jobs (shellId is the requestId); status pushed before send and stop answer; race-free draft claim. - ui: optimistic updates on web (useOptimistic) and terminal (TuiScope.optimistic, extended in Chord with a reducer and a pending flag), pending states for long work, visible rollback, load waterfalls removed; merged with the one composer and immediate first send (ccff9876e) and the folder + button (5a31a6d5f). docs/optimistic-ui.md describes the pattern. --- apps/p2/docs/handoff.md | 1 + apps/p2/docs/mcp-durable.md | 4 +- apps/p2/docs/optimistic-ui.md |

Overlays ignored it, so an extension question shown as an overlay left pi reporting `working` over OSC 7501. Example: pi-ask-user in its default overlay mode inside Herdr App never shows the session as blocked and never notifies. ## Change - Each overlay opened with `blocked` registers its own program status source (`extension-overlay:N`) after `showOverlay()` and clears it when the overlay calls `done()`. - The status stays while the overlay is hidden with `setHidden()` or covered by another overlay: the question is still unanswered. - Separate sources per overlay, so closing one keeps other open questions, dialogs and login prompts blocked. With several blocking prompts, the most recently shown one supplies `kind` and `message`. - Overlays without `blocked` (loaders etc.) register nothing and cannot clear another overlay's status. - `/reload` and session switches drop overlays without calling `done()`; `resetExtensionUI()` now clears their blocked status so pi does not stay blocked. - Inline components are unchanged: they report the dialog shown in the editor slot, so a non-blocking component shown in its place clears the status until it closes. - Docs (`docs/tui.md`, `custom()` JSDoc) and changelog updated. ## Testing - `npm run check` - `test/interactive-mode-extension-dialogs.test.ts`: new regression test (two blocking overlays, one non-blocking overlay, hide, close in order) and one for clearing the status on reset. pi-ask-user still needs to pass `blocked` for its overlay prompts. --- packages/coding-agent/CHANGELOG.md | 1 + packages/coding-agent/docs/tui.md | 2 +- .../coding-agent/src/core/extensions/types.ts | 5 +- .../src/modes/interactive/interactive-mode.ts | 18 +++ ...interactive-mode-extension-dialogs.test.ts | 108 +++++++++++++++++- 5 files changed, 129 insertions(+), 5 deletions(-) diff --git a/packages/coding-agent/CHANGELOG.md b/packages/coding-agent/CHANGELOG.md index a7700b2a0..37efbc3ae 100644 --- a/packages/coding-agent/CHANGELOG.md +++ b/packages/coding-agent/CHANGELOG.md @@ -12,6 +12,7 @@ - Anthropic sessions now use message threads: each request sends only the new messages and the server continues from the previous reply, falling back to the full request when the conversation changed (for example after compaction or a tool list change).

For overlays it called `this.ui.hideOverlay()` once, which pops only the topmost entry of the TUI overlay stack. Trace: an extension opens two overlays with `ctx.ui.custom({ overlay: true })`, then the user runs `/reload`. Reset removes the upper overlay; the lower one stays on screen, gets focus back and keeps receiving input, although the extension instance that created it is gone. A hidden overlay (`handle.setHidden(true)`) also stays in the stack and can be shown again by stale code. Blindly clearing the whole stack is not correct either: pi opens its own overlays (the header logo easter egg in `components/easter-egg-3d.ts`). With the old code, a reset while the easter egg was topmost removed the easter egg and left the extension overlay. ## Fix `showExtensionCustom` records each overlay it opens in `extensionOverlays` (handle -> removal function). The same function serves `done()` and `resetExtensionUI()`: it hides the overlay, clears its blocked program status (#11851) and disposes its component. Deleting the map entry first makes a second call a no-op, so a late `done()` after reset does not dispose twice. Reset calls it for every recorded overlay, newest first, including hidden ones. Overlays not opened by extensions are left alone. This replaces the separate `blockingOverlaySources` set and reset loop added in #11851. Pending `ctx.ui.custom()` promises of removed overlays stay unsettled, matching how reset already treats inline dialogs. ## Testing - New regression test in `test/interactive-mode-status.test.ts`: a pi-internal overlay plus three extension overlays (one hidden), then reset. Checks that the extension overlays are gone and disposed, the internal overlay remains and receives input. Fails without the fix. - `test/interactive-mode-status.test.ts`, `test/interactive-mode-extension-dialogs.test.ts`, `test/interactive-mode-paste.test.ts`, `test/suite/regressions/5943-session-start-notify.test.ts` pass. - `npm run check` clean. --- packages/coding-agent/CHANGELOG.md | 1 + .../src/modes/interactive/interactive-mode.ts | 55 ++++++++------ ...interactive-mode-extension-dialogs.test.ts | 11 +-- .../test/interactive-mode-status.test.ts | 76 ++++++++++++++++++- 4 files changed, 113 insertions(+), 30 deletions(-) diff --git a/packages/coding-agent/CHANGELOG.md b/packages/coding-agent/CHANGELOG.md index 37efbc3ae..223e7f851 100644 --- a/packages/coding-agent/CHANGELOG.md +++ b/packages/coding-agent/CHANGELOG.md @@ -36,6 +36,7 @@ - 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.
