# --- Extension upgrade regression test support ---
#
# Validates the upgrade template (age--<VER>--y.y.y.sql) by simulating an
# extension version upgrade entirely within "make installcheck". The test:
#
#   1. Builds the default install SQL (age--<CURR>.sql) from current HEAD's
#      sql/sql_files. This is what CREATE EXTENSION age installs.
#   2. Builds a synthetic "initial" version install SQL from the version-bump
#      commit in git history. This represents the pre-upgrade state.
#   3. Stamps the upgrade template to upgrade from the initial version to the
#      current version.
#   4. Temporarily installs the synthetic files into the PG extension directory
#      so that CREATE EXTENSION age VERSION '<INIT>' and ALTER EXTENSION
#      age UPDATE TO '<CURR>' can find them.
#   5. The age_upgrade regression test exercises the full upgrade path: install
#      at INIT, create data, ALTER EXTENSION UPDATE to CURR, verify data.
#   6. The test SQL cleans up the synthetic files via a generated shell script.
#
# This forces developers to keep the upgrade template in sync: any SQL object
# added after the version-bump commit must also appear in the template, or the
# upgrade test will fail (the object will be missing after ALTER EXTENSION UPDATE).
#
# Because the default install SQL comes from HEAD, all 31 non-upgrade tests
# run with every SQL function registered — no functions are missing.
#
# Graceful degradation — the upgrade test is silently skipped when:
#   - No git history (tarball build): AGE_VER_COMMIT is empty.
#   - No upgrade template: age--<CURR>--y.y.y.sql does not exist.
#   - A real (git-tracked) upgrade script from <CURR> already exists
#     (e.g., age--1.7.0--1.8.0.sql is committed): the synthetic test is
#     redundant because the real script ships with the extension.
# Current version from age.control (e.g., "1.7.0")

# --- Upgrade test file lifecycle during installcheck ---

# in the PG extension directory for CREATE EXTENSION VERSION and ALTER
# EXTENSION UPDATE to find them, but we must not leave them installed
# permanently (they would confuse users).
#
# Solution: A Make prerequisite installs them before pg_regress runs, and the
# test SQL removes them at the end via \! (shell escape in psql). A generated
# cleanup script (regress/age_upgrade_cleanup.sh) contains the exact absolute
# paths so the removal works regardless of the working directory. EXTRA_CLEAN
# also removes them on "make clean" as a safety net.
#
# This adds a prerequisite to "installcheck" but does NOT override the PGXS
# recipe, so there are no Makefile warnings.
