From d2ff70eac95e1941a1c158b0334db145bf5907af Mon Sep 17 00:00:00 2001 From: jnasbyupgrade Date: Thu, 16 Jul 2026 16:49:25 -0500 Subject: [PATCH 01/17] Add extension update test that runs the full suite against an upgrade MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit test/build/upgrade.sql is a fast smoke check (via pgxntool 2.1.0's test-build feature): install 0.9.6 (oldest version we ship a full script for) and ALTER EXTENSION UPDATE, rolled back. That alone doesn't prove much — it never runs the actual test suite against the upgraded state. test/deps.sql now selects between installing fresh (current version) or via the upgrade path, based on a count_nulls.test_load_mode GUC the Makefile sets via PGOPTIONS (TEST_LOAD_SOURCE=fresh|upgrade). Since every test file loads deps.sql, `make test-update` reruns the whole existing suite (extension_tests, sanity, simple) against the upgraded install, comparing against the exact same expected/*.out as `make test` — proving the upgrade behaves identically to a fresh install rather than just completing without error. Modeled on cat_tools's test/install/load.sql approach (see their new_functions-pgxntool-2.1.0 branch), adapted to count_nulls's simpler single-file test/deps.sql structure instead of introducing a separate test/install fixture, since count_nulls's suite already installs the extension per test file (into different schemas) rather than once globally. sql/count_nulls--0.9.6.sql isn't picked up by base.mk's DATA wildcard (which only covers upgrade scripts and the current version file), so it's added to DATA explicitly. Filed as a pgxntool bug: Postgres-Extensions/pgxntool#48.

Replaces the per-test-file hardcoded schema literals (schema_to_load_count_nulls / public) - a stand-in for real schema-qualification coverage that only ever tested two fixed, always- lowercase names - with a single TEST_SCHEMA make var, propagated the same way as TEST_LOAD_SOURCE via a GUC, applied uniformly for the whole test run. This also resolves an architectural conflict between the two: a real pg_upgrade leaves the extension in exactly one schema, which cannot simultaneously match two different per-file hardcoded literals, so 'existing' mode needs every file installing into the same run-wide schema to produce comparable output. sanity.sql previously bypassed test/deps.sql entirely (a bare, unconditional CREATE EXTENSION), which broke outright under 'existing' mode ("extension already exists"); it now respects both TEST_LOAD_SOURCE and TEST_SCHEMA like the rest of the suite. Locally: `make test TEST_SCHEMA=Quoted` exercises a schema requiring SQL identifier quoting (mixed case - unquoted would fold to lowercase and silently test 'public' again).

Proves an install/update/pg_upgrade sequence didn't silently drop+reinstall the extension it's meant to be testing - a stray CASCADE, a logic bug, or a bad CI step would otherwise fall through to a silent fresh reinstall and still report green. bin/test_existing factors the install -> plant guard -> update/upgrade -> assert -> drop guard -> run suite sequence (needed by both the extension-update-test and pg-upgrade-test CI jobs) into one committed, parameterized script instead of duplicating it as inline YAML. Modeled on Postgres-Extensions/cat_tools's script of the same name, with two differences: count_nulls has no pg_upgrade-unsafe old version to bridge past (it has always been pure SQL functions, no SELECT-*-over-catalog views), and its suite has its own legitimate (harmless - always rolled back) DROP EXTENSION test, so here the guard is dropped before run-suite instead of surviving through it.

A small old_pg/new_pg matrix (10->17, 12->17) x schema, not the full PG matrix, to keep cost reasonable given this is the most expensive job (installs two full PostgreSQL majors and runs the real pg_upgrade binary per leg). - changes: cheap docs-only gate so the three heavy jobs above can skip themselves on doc-only pushes without leaving the required check stuck Pending. - all-checks-passed: single stable required-status-check name; asserts its own needs list matches the actual job set so a new job can't be silently omitted from the gate. Locally validated end to end on this container's PG12/PG17 clusters, including a real binary pg_upgrade (PG12 -> PG17, extension carried at 0.9.6, updated to 1.0.0, guard proven through every step) before trusting this as CI YAML.

Captured from a real `make test TEST_SCHEMA=Quoted` run with zero TAP-level failures (`grep -c '^not ok' test/results/*.out` = 0 in every file) - the only difference from the default expected output is the schema name. sanity.out needs no alternate: its assertions are all unqualified, so its output doesn't vary by schema. Verified after regenerating: `make test`, `make test-update`, `make test TEST_SCHEMA=Quoted` and `make test-update TEST_SCHEMA=Quoted` all report "All 3 tests passed" with zero regression.diffs.

Previously both jobs hardcoded the same [17..10] list independently - exactly the drift risk this fixes (a new PG major meant editing two places, and forgetting one would silently undertest it). count_nulls needs only ONE floor, unlike cat_tools's three-constant version (NEWEST/CURRENT_FLOOR/LEGACY_FLOOR): 0.9.6 is pure SQL over anyarray/json/ jsonb with no catalog-version sensitivity, so it installs on every supported major - there's no PG10-only legacy leg to carve out the way cat_tools's pre-0.2.2 scripts need. Also documents, at pg-upgrade-test, the deliberate decision NOT to add cat_tools's companion pg-upgrade-stepwise job (one cluster climbing every major in sequence): that job protects against a regression at one specific major-to-major boundary, relevant to cat_tools's catalog-touching views but not to count_nulls's pure SQL functions. Pure refactor - the derived list resolves to the same PG majors as before ([17,16,15,14,13,12,11,10]), confirmed by running the bash derivation standalone.

TEST_SCHEMA is now optional: empty means don't CREATE SCHEMA/SET search_path at all, landing wherever the session's own ambient search_path resolves; non-empty explicitly targets that schema as before. Both legs matter and run in CI - genuinely different code paths. Where the extension lands when nothing targets it is not always 'public' - this suite's own pgTAP setup already puts its own schema first on search_path before deps.sql runs, so the empty leg lands there instead. That's not a bug to paper over (it's actually useful: it proves nothing is hardcoded to 'public'), so assertions that need a known expected schema (test__check_ncs, test__shutdown__drop_all) fall back to discovering the real location dynamically (ncs()) or skip when there's no fixed expectation, rather than assuming one. bin/test_existing's create_extension_in_schema helper and bin/test_existing_sql/plant_guard.sql both gained the same empty/non-empty branch (a quoted empty identifier is a real Postgres syntax error, so the empty case can't just always emit `CREATE SCHEMA "" `). Also moves test/pg_upgrade/*.sql to bin/test_existing_sql/ (they're helpers for bin/test_existing, not part of the pg_regress suite, so they belong under bin/ alongside the script that uses them), and removes test/sql/simple.sql: it existed to exercise "the other" schema before TEST_SCHEMA existed, dressed up as an on-search-path test, but functions.sql's own calls are all %I-qualified via ncs() regardless of search_path - so its search_path manipulation never actually changed anything, and the schema coverage it stood in for is now done properly (and more thoroughly - two legs, not one) by the TEST_SCHEMA matrix on extension_tests.sql itself. Confirmed no coverage is lost: everything simple.sql exercised (test__definition, test__functionality, via functions.sql) already runs identically inside extension_tests.sql.

NEWEST bumped 17->18 in the single-source PG-major derivation. Removed comments that leaned on cat_tools context to justify a design choice in this repo's own CI (e.g. "unlike cat_tools's pg-upgrade-test, which has to dig itself out of...") - every comment here should stand on its own reasoning; a reader of this repo has no reason to know cat_tools's history. Reworded the "worth doing anyway" phrasing into something that actually reads coherently. Also hardened the docs-only-changes step: it now writes docs_only=false as its literal first action, so any early exit or error further down leaves the fail-safe default in place instead of relying on every branch remembering to set it.
