# Per-recipe harness config for discourse (Phase 2 Q4.6 — forum; postgres + redis + sidekiq).
#
# Discourse (bitnamilegacy/discourse) is a slow-booting Rails app: the recipe healthcheck polls
# /srv/status, and a cold first boot (DB migrate + asset precompile) regularly takes 15-25 min on
# cc-ci's single node, so the deploy/HTTP timeouts are generous. /srv/status returns 200 only once the
# app is actually serving (the canonical "is discourse up" signal — NOT "/", which may redirect to setup).
HEALTH_PATH = "/srv/status"
HEALTH_OK = (200,)
DEPLOY_TIMEOUT = 3600  # slow Rails cold boot (15-25min) on the 7-GiB single node; bumped 2400→3600 for
# headroom after full4's base deploy timed out at 2400s (RAM/CPU-constrained boot + image re-pull).
HTTP_TIMEOUT = 1200

# Slow-cold-boot handling: the recipe-PR (recipe-maintainers/discourse#1) bumps the app healthcheck
# `start_period` to a LITERAL 20m for the HEAD. discourse's 15-25min Rails cold boot (DB migrate +
# asset precompile) exceeds the published 5m start_period → swarm would kill the still-booting app.
# start_period CANNOT be an env var (abra validates the literal compose 'duration' BEFORE substitution
# → `FATA ...Does not match format 'duration'`; Adversary-reproduced, REVIEW-2 4b862f6), so a literal
# recipe-PR bump is the only §9-compliant way to widen it. start_period is grace-only (a healthy check
# still marks healthy immediately → fast hosts unaffected). Precedent: lasuite-drive collabora PR.
# TIMEOUT (abra's internal convergence wait) is raised to outlast the boot.
#
# UPGRADE-tier BASE (compose.ccci.yml + UPGRADE_BASE_VERSION): upgrade-to-latest must ALWAYS run
# (plan-ccci-compose-overlay-policy.md §1). The from-version is the latest published 0.7.0+3.3.1
# (UPGRADE_BASE_VERSION below; the PR head is 0.7.0-based, so 0.7.0 is the true predecessor — not the
# default [-2]=0.6.3). The published 0.7.0 has TWO blockers, both resolved by the policy-blessed
# minimal base overlay compose.ccci.yml (see its header), neither weakening a test:
#   (1) it pins the Docker-Hub-removed `bitnami/discourse:3.3.1` (404) → overlay re-pins app+sidekiq to
#       `bitnamilegacy/discourse:3.3.1` (namespace-only, identical image), the same re-pin the PR makes;
#   (2) its 5m start_period is too tight for the 15-25min Rails boot → overlay widens it to 20m (grace).
# install_steps.sh provides the overlay; CHAOS_BASE_DEPLOY skips the clean-tree gate on the untracked
# overlay; it persists across the head checkout (idempotent — the PR head already re-pins + ships 20m).
# Upgrade crossover: 0.7.0 (re-pinned base) → PR head; full assertions run on the HEAD. The 0.7.0
# *custom* tests are not separately run (custom tier runs once, on the head — policy §1 allows skip+record).
CHAOS_BASE_DEPLOY = True
UPGRADE_BASE_VERSION = "0.7.0+3.3.1"
EXTRA_ENV = {
    "TIMEOUT": "3600",  # abra's internal convergence wait; matches DEPLOY_TIMEOUT (slow Rails boot headroom)
    "COMPOSE_FILE": "compose.yml:compose.ccci.yml",

def BACKUP_VERIFY(domain):
    """Post-backup integrity check (Q4.6, same race ghost F2-14b hit). The recipe's backupbot db
    pre-hook (`/pg_backup.sh backup`) dumps the discourse postgres DB to `/var/lib/postgresql/data/
    backup.sql` (gzip), then restic captures that path. On the loaded single CI node the db container
    is cycled by the immediately-preceding UPGRADE tier (chaos redeploy), and at backup time the
    pre-hook's pg_dump can race that cycle — the dump is truncated/never written, restic snapshots an
    empty/absent path, and a later restore reimports nothing → the seeded ci_marker is lost (P4 RED;
    observed full1/full2 WITH upgrade, vs full3 WITHOUT upgrade green). Proven first-hand: the pre-hook
    itself succeeds on a stable db (manual exec → valid 922KB dump), so the failure is the cycle race,
    not the script. This probe proves the dump completed: backup.sql exists, is a VALID gzip, non-empty.
    False → the harness re-runs the WHOLE backup with a re-stabilised db (run_recipe_ci _perform_op,
    caps at 3 then proceeds — a persistent failure still surfaces RED at restore, so it weakens no
    assertion; it only retries a flaky CAPTURE). READ-ONLY."""
