Worker polls the DB every interval (production 30s) and every
poll ran SELECT * FROM tasks: full rows including result_text
and error_text (up to 4000 chars each) for every task ever,
growing with history. load_tasks now selects only the columns
pick_next actually needs (id/project/prompt/status/depends/
priority/timestamps/executor) and only queued/completed/merged
rows; running/failed rows are neither ready nor completed, so
excluding them cannot change pick_next. get_task still does
SELECT * for the single claimed task. Plus CREATE INDEX IF NOT
EXISTS idx_tasks_status on tasks(status) in both SQLite
init_db and the Postgres schema, so the poll filter stops being
a full table scan on old databases too. Test: load_tasks returns
only queued+completed out of queued/completed/running/failed.
Worker pool: workers table + register/heartbeat (heartbeat is
registration, no 404), GET /workers with alive (120s default),
POST /workers/heartbeat (X-API-Key, missing worker_id 400).
Tasks gain executor (local/docker/cloud, None = any worker);
worker claim filters by executor in pick_next and in the CAS
WHERE clause, CAS semantics unchanged; CloudExecutor _name
now correctly returns cloud, not local.
CloudExecutor: generic HTTP runner interface (endpoint from
explicit arg or CLOUD_RUNNER_ENDPOINT, auth header name only,
token value only from env into the request header, never into
logs/body/errors); no endpoint configured = explicit failure,
never silent downgrade. Vendor adapters (ECS/Cloud Run) are
out of scope, documented as such.
Auto PR: projects.auto_pr (0/1, create-time only, no PATCH
route exists); POST /tasks/{id}/pr (maintainer+ via
approve_merge) only for merged tasks (else 409); skip reasons
in order: auto_pr_disabled, no_worktree, no_remote, no_gh,
gh_not_authenticated — all return 200 with pr_skipped, task
stays merged, no push attempted; push/pr-create failure
returns 502 with step, task stays merged; success writes
pr_url/pr_number and audits pr_created. No default auto-push
from the worker. Remote URLs in errors are scrubbed of
userinfo; gh credentials are managed by gh itself, never
stored by the control plane.
Tests: host 27 pass, cloud 323 pass (8 skipped are
environment-dependent real-Postgres tests).
Projects gain repo_url (validated: https:// or git@ only, no
userinfo/password, no file:// or local paths; old DBs get the
column via idempotent ALTER in both SQLite and Postgres init).
Worker resolves a project's repo_url to a local checkout under
--repos-dir (default ./repos) before dispatch: clone if absent,
verify remote origin matches and fetch if present, never force
reset/clean, never push (push needs write credentials the
control plane does not store). Resolve failure fails the task
with a clear error, never completed. Docker workers need
repos_dir under a same-path extra mount (e.g.
/var/lib/codex-app-server/repos).
Also: driver-missing test is now mocked instead of depending
on the host really having no psycopg driver installed.
Deploy package: Caddyfile template exposing only /webhooks/*
and /oauth/* (tasks/projects/admin stay 403) plus a
webhook-secret generator script that never prints the secret.
Tests: host 27 pass, cloud 286 pass (8 skipped are
environment-dependent real-Postgres tests).
Replace the PostgresDatabase skeleton with a real implementation:
psycopg (v3) first, psycopg2 second, lazy load, missing driver
still raises PostgresDriverMissingError with no silent SQLite
fallback. A sqlite3-style adapter (PgConnection/PgCursor/PgRow)
translates ? placeholders to %s outside string literals, maps
UNIQUE/FK violations, lock errors and connection failures to
explicit Postgres error types, and handles INSERT OR REPLACE,
PRAGMA table_info, AUTOINCREMENT and FTS5 refusal. POSTGRES_SCHEMA
covers all business tables with tasks result columns; server
init_db uses it under CLOUD_DB_BACKEND=postgres, SQLite path
unchanged. migrate_sqlite_to_postgres.py copies rows with
ON CONFLICT DO NOTHING and reseeds identity sequences.
Tests: cloud 239 (235 pass, 4 skipped without a real server),
host 27 pass; real-server tests skip unless CLOUD_TEST_PG_DSN
is set.
