From 1e96c6b0a0f06cad576086243f3d06397c4ddf44 Mon Sep 17 00:00:00 2001 From: Noah Zweben Date: Wed, 12 Aug 2026 18:03:09 -0700 Subject: [PATCH] =?UTF-8?q?fix(telegram):=20v0.0.7=20reliability=20rollup?= =?UTF-8?q?=20=E2=80=94=20state-dir,=20PID=20guard,=20ppid=20watchdog,=20i?= =?UTF-8?q?nstall=20stdout=20(#1424)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * fix(telegram): honor TELEGRAM_STATE_DIR/CLAUDE_CONFIG_DIR in skills and server The server already reads TELEGRAM_STATE_DIR for multi-bot setups, but the /telegram:access and /telegram:configure skills hardcoded ~/.claude/channels/telegram/ in 11 places. So with a custom state dir the skill writes access.json to the default location while the server reads from the override — pairing and allowlist edits silently don't take effect. Skills now resolve the state dir via shell expansion (TELEGRAM_STATE_DIR → CLAUDE_CONFIG_DIR/channels/telegram → ~/.claude/channels/telegram) before any read/write. Server gets the same CLAUDE_CONFIG_DIR fallback. Also adds Bash(echo)/Bash(chmod) to configure skill's allowed-tools (chmod was already documented but not allowlisted). * fix(telegram): verify stale PID is a server.ts process before SIGTERM PID files race with OS PID recycling. The lockfile from #1349 stored only a PID; after enough churn that PID can be reassigned to anything — including the new launch's own bun-run wrapper. SIGTERMing the wrapper closes our stdin and triggers immediate self-shutdown ('replacing stale poller' then 'shutting down' within seconds — matches #1459 item 3). Now check 'ps -p -o args=' contains 'server.ts' before killing. execFileSync (no shell); whole block already try/catch so Windows/ps-missing falls through to just overwriting the lockfile. * fix(telegram): drop ppid watchdog check; redirect bun install stdout to stderr Two v0.0.5/0.0.6 regressions causing the plugin to fail at startup: 1. The orphan watchdog's process.ppid !== bootPpid check false-fires when the bun-run/shell wrapper exits or execs during normal startup and we get reparented to init — plugin self-terminates ~5s after launch. Stdin-close alone is the correct signal: the kernel closes the MCP pipe on any CLI death regardless of intermediate wrappers, so the ppid check was both unnecessary and harmful. (#1467; also the actual cause of #1459 item 3 and likely #1425.) 2. 'bun install --no-summary' in the start script writes to stdout, which is the MCP JSON-RPC transport. The harness sees non-JSON bytes during the handshake and drops the connection ('Failed to connect'). Redirect install output to stderr. (#1470; also explains #1425 on Windows.) --------- Co-authored-by: Claude Co-authored-by: Bryan Thompson <238056179+bryan-anthropic@users.noreply.github.com> --- .../telegram/.claude-plugin/plugin.json | 2 +- external_plugins/telegram/package.json | 2 +- external_plugins/telegram/server.ts | 31 ++++++++++++------- .../telegram/skills/access/SKILL.md | 26 +++++++++++----- .../telegram/skills/configure/SKILL.md | 24 ++++++++++---- 5 files changed, 57 insertions(+), 28 deletions(-) diff --git a/external_plugins/telegram/.claude-plugin/plugin.json b/external_plugins/telegram/.claude-plugin/plugin.json index e1edd215..41b42894 100644 --- a/external_plugins/telegram/.claude-plugin/plugin.json +++ b/external_plugins/telegram/.claude-plugin/plugin.json @@ -1,7 +1,7 @@ { "name": "telegram", "description": "Telegram channel for Claude Code \u2014 messaging bridge with built-in access control.
