add autobuild repro_command for triage script reproduction#90
Merged
Conversation
Emits the exact `(cd <ws> && env KEY=val ... python3 <script>)` command
autobuild would have used to run a single workspace script — same defaults
+ per-pattern overrides as `env_config.build_env_for_script`, but starts
from `{}` instead of `os.environ.copy()` so the output is portable across
shells.
Intended for triage handoffs: when pasting a failing script into a chat
or issue, the reader gets a self-contained reproduction that matches
autobuild's environment exactly (PYAUTO_TEST_MODE, PYAUTO_SMALL_DATASETS,
etc.), not just `python3 <file>` which silently omits them.
Wired into the dispatcher under a new "Triage support" section. Verified
end-to-end against the 2026-05-20 release-prep run: spot-check of the
Cluster A `imaging/visualization.py` failure reproduces the recorded
`AssertionError: dataset.png missing` verbatim.

Summary
Add
autobuild repro_command <script>— a small helper that emits the exact shell command autobuild would have used to run one workspace script, including the env vars from the workspace'sconfig/build/env_vars.yaml. Solves a recurring triage-handoff pain point: when pasting failing scripts into chats or issues, the chat-side reader couldn't reproduce the failure becausepython3 <script>omits the autobuild-injected env (PYAUTO_TEST_MODE,PYAUTO_SMALL_DATASETS,PYAUTO_FAST_PLOTS, etc.) and per-patternset:/unset:overrides. The new helper emits a self-contained one-liner like(cd <workspace> && env KEY=val ... python3 <script>)so the chat-side reproduction matches autobuild's environment exactly.API Changes
None — internal additions only. New shell subcommand
autobuild repro_command, new Python moduleautobuild/repro_command.py, and one dispatcher edit (bin/autobuild). No existing functions, classes, or arguments are modified.See full details below.
