CHANGELOG.md

··· 2 2 3 3 ## Unreleased 4 4 5 + ### Per-namespace isolation — `PTY_ROOT` + `pty --root <path>` 6 + 7 + - **New canonical env var `PTY_ROOT`** for the state registry directory (default `~/.local/state/pty`). The pre-existing `PTY_SESSION_DIR` still works and continues to point at the same registry; when only the legacy name is set, `pty` emits a one-time deprecation notice to stderr per process. Precedence: `PTY_ROOT > PTY_SESSION_DIR > default`. 8 + - **New env var `PTY_ROOT_LEGACY_SILENT=1`** — suppresses the `PTY_SESSION_DIR` deprecation notice for callers (test suites, long-lived legacy scripts) that are on a migration schedule. 9 + - **New global flag `pty --root <path>`** — pins the state registry for a single invocation. Parsed before subcommand dispatch, so every subcommand (`list`, `gc`, `kill`, `tag`, `attach`, `up`, `run`, …) transparently scopes. Equivalent to `PTY_ROOT=<path> pty <cmd>`. 10 + - **`pty gc --print-launchd-plist` per-root parametrization.** On the default root the emitted plist retains its Label `com.myobie.pty.gc` (backwards-compatible with existing installs) and its previous log path. On a non-default root the Label becomes `com.myobie.pty.gc.<basename-of-root>` — reverse-DNS-safe (non-`[A-Za-z0-9._-]` runs collapse to a single hyphen) — and the log path is `<PTY_ROOT>/gc.log`. Two networks can each install their own gc plist without a launchd-Label collision, and each network's gc noise stays inside its own registry. 11 + - **`PTY_ROOT` added to the isolate-env allow-list** (`src/server.ts:ISOLATED_ENV_ALLOWLIST`) alongside `PTY_SESSION_DIR`, so `pty run --isolate-env` children still see the pinned registry. 12 + - **Emitted plist now uses `PTY_ROOT`** in its `EnvironmentVariables` block — the deprecation notice fires anew every launchd tick if you re-use the legacy env, so a mid-migration installer gets loud, actionable feedback in `gc.log` instead of silent drift. 13 + - **README** — new "Namespaces" section under "On-disk format" documenting soft (tag-filter) and hard (`--root`/`PTY_ROOT`) namespacing, with the smalltalk `st.network=<value>` tag called out as a specific application of the soft primitive. 14 + - **`docs/disk-layout.md`** — directory table now references `$PTY_ROOT`; legacy env name called out with the migration hint. 15 + - Tests in `tests/pty-root.test.ts` cover: env-var precedence, deprecation notice fires exactly once and is silenced by `PTY_ROOT_LEGACY_SILENT`, `--root` overrides both env vars, `--root` without a value errors clearly, default-root plist retains legacy Label, non-default root gets a suffixed Label + per-root logPath, and a pathological basename (spaces) sanitizes into a launchd-safe suffix. 16 + 5 17 ### Fixes 6 18 - **`@myobie/pty/tui` `CellBuffer` — wide-char (2-cell) glyph rendering fixed.** Two root causes, both in `src/tui/buffer.ts`: 7 19 1. `writeAnsi` iterated the input string by UTF-16 code unit, splitting astral-plane codepoints (emoji like `📬`, `📭`, `📫` — U+1F4XX) into two lone surrogate halves stored as separate width-1 cells. Downstream `diff()` and `fullRender()` emitted the halves independently; a modern host terminal (kitty, iTerm2, Ghostty) recombined them as one wide glyph, but the CellBuffer's cell-index → terminal-column mapping was off by one on every emoji. Fixed by detecting surrogate pairs and combining them into one Cell whose `char` holds the full 2-code-unit string.

··· 171 171 172 172 ### On-disk format 173 173 174 - Session metadata, events, and supporting files all live under `$PTY_SESSION_DIR` (default `~/.local/state/pty`). The full layout — file naming, JSON shape, atomic-write contract, event types, stability tiers — is documented in [docs/disk-layout.md](docs/disk-layout.md). Third parties can read these files directly to skip the Node CLI's startup cost; `git`-style command forwarding (`pty <subcommand>` resolves to a `pty-<subcommand>` binary on `$PATH`) lets you ship native fast-path readers as `pty` subcommands. 174 + Session metadata, events, and supporting files all live under `$PTY_ROOT` (default `~/.local/state/pty`). The full layout — file naming, JSON shape, atomic-write contract, event types, stability tiers — is documented in [docs/disk-layout.md](docs/disk-layout.md). Third parties can read these files directly to skip the Node CLI's startup cost; `git`-style command forwarding (`pty <subcommand>` resolves to a `pty-<subcommand>` binary on `$PATH`) lets you ship native fast-path readers as `pty` subcommands. 175 + 176 + ### Namespaces 177 + 178 + `pty` is single-registry by default — every `list`, `gc`, `kill`, `tag`, and `attach` operates on the same directory tree. Two tools sharing a machine can compose two levels of isolation on top of that: **filter by tag** (soft: everyone still sees each other but scoped views are cheap) and **switch registry** (hard: the underlying state directory is different, sessions are invisible across). 179 + 180 + **Soft isolation via tags** — any tool can stamp a namespace tag at spawn and filter on it: 181 + 182 + ```sh 183 + pty run --tag app=payments -- ./bin/worker 184 + pty list --filter-tag app=payments # only payments sessions 185 + pty list --filter-tag app=payments --filter-tag role=worker # combine, ALL must match 186 + ``` 187 + 188 + The primitive is `--filter-tag k=v` (repeatable, matches ALL). Any tool layering on top — smalltalk uses `st.network=<root>` to distinguish agents in its network from an operator's ad-hoc pty use — reads and writes tags through the same primitive; no pty semantics for the outer tool's key. 189 + 190 + **Hard isolation via `--root`** — pin the state registry per call, or per environment: 191 + 192 + ```sh 193 + pty --root /var/lib/pty-eval list # one-off scope for this invocation 194 + PTY_ROOT=/var/lib/pty-eval pty list # scope for a whole shell / process tree 195 + ``` 196 + 197 + Distinct roots share no sockets, no metadata, no events, no gc. A launchd cron (`pty gc --print-launchd-plist`) inherits the current `$PTY_ROOT` and bakes a per-root Label (`com.myobie.pty.gc.<basename>`) plus per-root log path, so N isolated registries can each install their own gc plist without collision. On the default root the Label stays `com.myobie.pty.gc` — existing installs survive an upgrade unchanged. 198 + 199 + `PTY_SESSION_DIR` (the pre-Phase-2 name for the same env var) still works and emits a one-time deprecation notice. Set `PTY_ROOT_LEGACY_SILENT=1` to suppress the notice while migrating. 175 200 176 201 ### Project Files 177 202
