From e04264e55bacd465843be1f1a4f69e14bf9b8405 Mon Sep 17 00:00:00 2001 From: Rhuan Barreto Date: Wed, 15 Apr 2026 21:30:34 +0200 Subject: [PATCH] fix(telemetry): await initTelemetry so command_executed carries repo_id MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The CLI kicked off initTelemetry() with `void`, so the async getRepoContext() call was still in flight when the Commander preAction hook fired `command_executed` — meaning `repo_id` was always null on that event (0/90 in the last 90 days of v0.28.0 on PostHog) and ~25% of `command_completed` events also missed it when the process exited before the snapshot resolved. Await initTelemetry() before command handlers run, and parallelize the three git probes inside getRepoContext() (rev-parse --is-inside-work-tree gates first, then `git config --get remote.origin.url` runs concurrently with resolveDefaultBranch, which itself fires symbolic-ref and rev-parse --abbrev-ref in parallel). Windows spawn is the dominant cost (~25ms each), so going serial added ~80ms p50 / ~100ms p95 to every CLI invocation; parallelizing drops that to ~63ms p50 / ~84ms p95 (a ~21% reduction on the hot path). Non-git directories are unchanged — the gate stays serial. Verified: - Git repo with remote: `command_executed` carries `repo_id` + `repo_host`. - Non-git directory: event fires, `repo_id=null, repo_is_git=false`. - ARCHGATE_TELEMETRY=0: 0 events (disabled path unchanged). - NODE_ENV=test: 0 events (test short-circuit unchanged). - `bun run validate` passes (639 tests, lint/typecheck/format/ADR/build).
