Description

TL;DR: every command run now sends a second event, command_finished, when it ends: command, seconds, outcome (ok, exit, error), and on failure the exception's class name. The command's own event is unchanged.

Why: track_command sends its event before the command body runs, so a comfy build push that died on a 400 and one that moved 20 GB are the same row, and nothing in the CLI's telemetry says how many of any command worked. cli:execution_error exists for comfy run only.

Before / After

  • The start event is unchanged, on purpose. Every count that reads it stays a count of commands, and a long-running command (launch, run) is still counted the moment it starts rather than when, or whether, it exits. A first draft moved the one event to the end; it would have undercounted launch and broke 15 tests that read the command's event as the one event. A command that never ends has a start row and no finish row, which is itself the answer.
  • command_finished carries error_type only, the class name, never the message: a message can carry a path or a credential. typer.Exit(0) is ok; a non-zero exit is exit with exit_code; Ctrl-C is error / KeyboardInterrupt. Everything propagates as before.
  • Consent and the env opt-out are untouched; both events go through the same track_event.

Closes BE-16760.

How has this been tested?

pytest: 7858 passed (7861 on the tracker branch), 2 failed, 38 skipped. Both failures are not from this change: test_node_deps.py::test_non_pep440_installed_version_is_unknown_not_a_crash and test_http.py::test_an_unloadable_supplement_falls_through_to_the_platform_roots fail identically on an unmodified main checkout in a fresh environment (Python 3.12; CI targets 3.10). ruff check and ruff format --check clean. The "Test CLI Tool on GPU runners" job fails on every PR in this repo today (10 of the last 10 runs, five authors) on tests/e2e/test_e2e_uv_compile.py, which this does not touch.

Six new tests: a return is ok and timed, the start row carries no outcome, a raise names the class and not the message and still raises, three exit codes, Ctrl-C. The test helpers that read "the" track call now read the command's own (first) call; two helpers in the provider fan-out tests likewise.

Not run: against real PostHog or Mixpanel.

Documentation

  • Not user-facing; the module docstring on track_command describes both events.

📝 Walkthrough

Walkthrough

track_command now emits a completion event with duration and outcome details. Tests verify event ordering, redaction behavior, provider event selection, and handling for normal returns, exceptions, interrupts, and exits.

Changes

Command completion tracking

Layer / File(s) Summary
Completion event implementation
comfy_cli/tracking.py
track_command measures wall-clock duration, classifies completion as ok, exit, or error, and emits command_finished before returning or re-raising.
Event ordering and outcome validation
tests/comfy_cli/test_tracking.py, tests/comfy_cli/test_tracking_providers.py
Tests verify the two-event contract, completion metadata, exception and exit handling, redaction behavior, and selection of the command's first provider event.

Reviewed the start/finish event lifecycle, exit/exception propagation, opt-out handling, and provider fan-out. No blocking findings. All 195 targeted tracking/provider tests pass locally on Python 3.10.

The GPU CI job remains red: its log shows the two uv-compile conflict-message tests failing, the same failures across these four PRs in code outside these changes. Other reported checks pass. I did not rerun GPU E2E or live analytics/provider operations.

track_command's docstring reserves exit_code for a non-zero typer.Exit, but a
typer.Exit(0) was sent with exit_code=0. It now records outcome "ok" alone,
and the test requires the key to be absent for a zero exit.

Self-review of the fix push, head 1b5b1bc, read cold.

Findings: none beyond the one addressed. The typer.Exit branch now writes outcome alone for a zero code and outcome plus exit_code otherwise, which is what the docstring promises; the parametrised test requires the key to be absent for 0 and equal to the code otherwise, and fails on the old code for the 0 case.

Checked: full suite on 1b5b1bc: 7861 passed, 38 skipped, 2 failed, the two pre-existing failures (test_node_deps non-PEP 440 version, test_http unloadable supplement) on files this branch does not touch.

Holding on a clean foreground launch reading as a failure. Reads as: each command also reports how it ended and how long it took. Head 1b5b1bc, judged as comfy-cli's owner.

Must

  • Correctness: a launch run in the foreground and stopped cleanly is recorded as a failure comfy_cli/command/launch.py:327. The builtin exit() raises SystemExit, which lands in the catch-all as error; treat it like typer.Exit by its code and test it.

Optional

  • Reachability: a background launch that succeeded reads as killed comfy_cli/command/launch.py:701. os._exit skips the finally, so no finish row is ever sent for it.
  • Contract: most Ctrl-C presses are not recorded as the docstring says comfy_cli/tracking.py:769. Most commands turn it into exit 130.
  • Modularity: the helper named for the last call returns the first tests/comfy_cli/test_tracking.py:50. A test trusting the name reads the wrong event.
  • Verbosity: the Ctrl-C branch repeats the catch-all below it comfy_cli/tracking.py:771. It records the same class name.

Clean: Scope, Resilience, Access, Tests, Rollout.
Native review: 9 findings, folded into the list above.
Checked: the new tests fail on main; a clean exit probed through the decorator recorded an error.
Bots: the zero-exit fix is in the pushed code and holds.
