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.

Without code mode the worker registry installs tool_search once for all deferred tools. --- apps/p2/docs/p2-notes.md | 51 +- apps/p2/plugins/chat/web.tsx | 69 +-- apps/p2/plugins/mcp/worker.ts | 17 +- apps/p2/plugins/models/fake.ts | 2 +- apps/p2/plugins/terminals/Terminal.tsx | 24 +- apps/p2/plugins/terminals/commands.ts | 162 +++++++ apps/p2/plugins/terminals/contract.ts | 97 +++- apps/p2/plugins/terminals/detached.ts | 11 + apps/p2/plugins/terminals/ghostty.ts | 30 +- apps/p2/plugins/terminals/keys.ts | 102 ++++ apps/p2/plugins/terminals/main.ts | 507 +++++++++++++++++--- apps/p2/plugins/terminals/plain.ts | 148 ++++++ apps/p2/plugins/terminals/protocol.ts | 91 +++- apps/p2/plugins/terminals/server.ts | 141 +++++- apps/p2/plugins/terminals/service.ts | 125 ++++- apps/p2/plugins/terminals/tool.ts | 316 ++++++++++++ apps/p2/plugins/terminals/tui.ts | 47 ++ apps/p2/plugins/terminals/worker.ts | 50 ++ apps/p2/src/runtime/durable.ts | 17 +- apps/p2/src/web/Chat.tsx | 33 +- apps/p2/src/web/style.css | 8 + apps/p2/test/p2/durable-registry.test.ts | 48 +- apps/p2/test/p2/terminal-agent-host.test.ts | 289 +++++++++++ apps/p2/test/p2/terminal-commands.test.ts | 91 ++++ apps/p2/test/p2/terminal-keys.test.ts | 50 ++ apps/p2/test/p2/terminal-plain.test.ts | 50 ++ apps/p2/test/p2/terminal-tool-unit.test.ts | 235 +++++++++ apps/p2/test/p2/terminal-tool.test.ts | 254 ++++++++++ 28 files changed, 2928 insertions(+), 137 deletions(-) create mode 100644 apps/p2/plugins/terminals/commands.ts create mode 100644 apps/p2/plugins/terminals/keys.ts create mode 100644 apps/p2/plugins/terminals/plain.ts create mode 100644 apps/p2/plugins/terminals/tool.ts create mode 100644 apps/p2/plugins/terminals/tui.ts create mode 100644 apps/p2/plugins/terminals/worker.ts create mode 100644 apps/p2/test/p2/terminal-agent-host.test.ts create mode 100644 apps/p2/test/p2/terminal-commands.test.ts create mode 100644 apps/p2/test/p2/terminal-keys.test.ts create mode 100644 apps/p2/test/p2/terminal-plain.test.ts create mode 100644 apps/p2/test/p2/terminal-tool-unit.test.ts create mode 100644 apps/p2/test/p2/terminal-tool.test.ts diff --git a/apps/p2/docs/p2-notes.md b/apps/p2/docs/p2-notes.md index f37341b1f..4f3c58810 100644 --- a/apps/p2/docs/p2-notes.md +++ b/apps/p2/docs/p2-notes.md @@ -29,7 +29,7 @@ P2_FAKE=1 npm start # http://127.0.0.1:8788, data in ~/.pi/p2 | --- | --- | --- | | `P2_DATA_DIR` | `~/.pi/p2` | data directory: `catalog.sqlite`, `sessions/.sqlite`, `settings.json`, `models.json`, `envs.json`, `mcp.json`, `mcp-auth.json`, `auth.json`, `radius.json`, `forwards.json` | | `PORT` | `8788` | listen port (loopback only), so p2 never collides with pi-mobile on 8787 | -| `P2_FAKE` | unset | `1`: the faux provider (`faux/faux-1`, echoes the prompt; `slow …` streams long; `rename-session ` calls the tool; `subagent`, `subagent-bad`, `subagent-answer`, `subagent-configure`, `subagent-send`, `subagent-archive`, `subagent-status` exercise subagents, `subagent <json>` calls the tool with those arguments, as do `team <json>`, `history_search|read|handoff <json>`, `location_envs|dirs|move <json>`, `tool_search <json>` and `mcp__<server>__<tool> <json>`; `codemode` runs a script calling bash and read, `codemode-restart` one whose slow middle call a restart interrupts, `codemode <script>` runs that script; `artifact <json>` calls the artifact tool with those arguments; `json <text>` answers exactly `<text>`; a one-shot agent whose task is not `json …`/`slow…` answers a small value matching its schema) | +| `P2_FAKE` | unset | `1`: the faux provider (`faux/faux-1`, echoes the prompt; `slow …` streams long; `rename-session <title>` calls the tool; `subagent`, `subagent-bad`, `subagent-answer`, `subagent-configure`, `subagent-send`, `subagent-archive`, `subagent-status` exercise subagents, `subagent <json>` calls the tool with those arguments, as do `team <json>`, `history_search|read|handoff <json>`, `location_envs|dirs|move <json>`, `tool_search <json>`, `terminal <json>` and `mcp__<server>__<tool> <json>`; `codemode` runs a script calling bash and read, `codemode-restart` one whose slow middle call a restart interrupts, `codemode <script>` runs that script; `artifact <json>` calls the artifact tool with those arguments; `json <text>` answers exactly `<text>`; a one-shot agent whose task is not `json …`/`slow…` answers a small value matching its schema) | | `P2_IDLE_MS` | `300000` | idle time before a session worker stops | | `P2_PROVIDER`, `P2_MODEL` | unset | default model for new sessions after settings.json's `defaultModel` (both or neither; Pi Mobile's `PI_MOBILE_PROVIDER`/`PI_MOBILE_MODEL` work too) | | `P2_RADIUS` | unset | `0`: disable the outbound Radius brain connection even when signed in | @@ -877,11 +877,49 @@ translated phone drawer and intercept chat taps.

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. Pass the selected model into filterModels() so the refresh keeps it selected by provider and ID. If it is gone, the existing fallback applies. The index is chosen once and the list is rebuilt once.

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).
