Summary

  • _ALLOWED_PRIVS_JSON = 'sql/allowed_privs.json' in views/__init__.py expects the allowed-privileges list under a sql/ subdirectory of each version bucket, matching the default bucket's layout. The PG17+ allowed_privs.json files for views and materialized views (both pg and ppas) were added directly under the 17_plus bucket directory instead, so render_template('views/pg/17_plus/sql/allowed_privs.json') never found them and silently fell through to the default bucket's list via the versioned template loader's fallback - which predates the MAINTAIN privilege and lacks 'm'.
  • Net effect: the MAINTAIN checkbox appears in the Grant Wizard for views/mviews on PG17+/EPAS17+, but ticking it and saving never actually grants MAINTAIN, because _parse_privileges drops any privilege not in allowed_acls.
  • Fix: moved the four affected allowed_privs.json files (views/mviews × pg/ppas) under sql/ to match the default bucket's layout, matching one of the two fixes the issue suggested and requiring no code changes.

Test plan

  • Added web/pgadmin/browser/server_groups/servers/databases/schemas/views/tests/test_allowed_privs_json_path.py, rendering the PG17 template path directly for all four combinations and asserting 'm' is present.
  • Confirmed all four scenarios fail against the pre-fix file layout (falling back to default, missing 'm') and pass with the fix.
  • Ran the full views.tests package - no regressions.
  • pycodestyle clean on the new test file.

Closes #10350

Merge Risk: ⚪ Minimal · up to 63727

This change makes PostgreSQL/EPAS 17+ views and materialized views load the privilege list that includes MAINTAIN, so selecting MAINTAIN in the Grant Wizard is no longer silently dropped. The only code change relocates configuration files; the remaining changes add tests. Adding a scenario that grants MAINTAIN end to end would strengthen the regression tests, but nothing blocks merging.

Review

The core fix is correct and working as expected. ViewNode.BASE_TEMPLATE_PATH = 'views/{0}/#{1}#' plus _ALLOWED_PRIVS_JSON = 'sql/allowed_privs.json' resolves views/pg/#170000#/sql/allowed_privs.json, and VersionedTemplateLoader falls back per-file, so a 17_plus/allowed_privs.json without the sql/ level was genuinely unreachable. Moving the four files is the right minimal fix, nothing references the old paths, and the schemas/catalog templates that also keep allowed_privs.json at the bucket root are consistent with their own _ALLOWED_PRIVS_JSON value, so no wider cleanup is needed.

Two problems with the test-fixture half, though.

1. The new 17_plus test folders will silently disable the entire views/mviews RE-SQL suite on PG17+

get_test_folder() (web/regression/re_sql/tests/test_resql.py:380-410) picks the first existing version directory and then os.listdirs it for .json scenario files — folder-level resolution, unlike get_test_file(), which falls back per file. That is why every other bucket (pg/15_plus, pg/16_plus, …) duplicates tests.json and test_mview.json.

The new views/tests/pg/17_plus and views/tests/ppas/17_plus contain only the two .sql files, so on a PG17+ server the runner resolves to those directories, finds zero JSON files, and runs no view/mview RE-SQL scenarios at all — including the ones this PR is trying to pin down. Both new directories need copies of tests.json and test_mview.json.

2. The RE-SQL (non-msql) fixtures for the same two scenarios are now stale as well

The sql() path re-filters through parse_priv_to_db(..., allowed_acls) (views/__init__.py:1487-1492), so the same ALL-collapse rule in parse_priv_to_db applies to reverse-engineered SQL too. Both affected scenarios grant the 7-privilege set to PUBLIC, and their expected RE-SQL still reads GRANT ALL ... TO PUBLIC:

  • views/tests/pg/default/alter_mview.sql:17 and views/tests/ppas/default/alter_mview.sql:17
  • views/tests/pg/default/alter_mview_change_grantee_priv.sql:17 and views/tests/ppas/default/alter_mview_change_grantee_priv.sql:17

These need 17_plus overrides with the explicit privilege list, exactly like the msql fixtures added here.

The TO <OWNER> lines and the alter_mview_drop_all_priv* fixtures are fine — the owner's PG17 ACL includes m, so 8-of-8 still collapses to ALL.

Minor

test_allowed_privs_json_path.py overrides setUp to pass, which skips the server connection but still relies on the regression harness for self.app. That works given how BaseTestGenerator is wired, it is just unusual for this directory.

@kundansable thanks, both of those were real, and both are fixed in d827f4c.

Your first point turned out to be even more clear cut than described, since I could reproduce it locally against PostgreSQL 18. With the branch as it was, regression/runtests.py --pkg resql --modules views completed in a tenth of a second having run no scenarios at all, exactly as you predicted from get_test_folder() resolving at folder level: it picked views/tests/pg/17_plus, found no JSON in it, and quietly ran nothing. Both 17_plus directories now carry copies of tests.json and test_mview.json, as every other bucket does, and 43 scenarios run again.

Your second point then showed up as two failures the moment the scenarios were running, in alter_mview.sql and alter_mview_change_grantee_priv.sql, both still expecting GRANT ALL ... TO PUBLIC. Both now have 17_plus overrides for pg and ppas, with the explicit privilege list. Worth noting that the reverse-engineered SQL renders the privileges in ACL character order (GRANT TRUNCATE, INSERT, DELETE, SELECT, TRIGGER, UPDATE, REFERENCES), which is not the order the msql fixtures carry, since those follow the order the client sent them in; I checked it is stable across runs rather than something set iteration order was deciding for us. The TO <OWNER> lines still collapse to ALL, as you said they would.

On the minor: setUp is overridden because the base class's version connects to the test server, which that test has no use for, given that it only renders a template. I have added a comment saying so rather than changing the structure.

Verified with PostgreSQL 18: 43 RE-SQL scenarios pass, plus the six scenarios of test_allowed_privs_json_path.py.

@coderabbitai On the ClassVar nitpick for scenarios in test_allowed_privs_json_path.py: I'm leaving it as it is. scenarios is the attribute testscenarios reads from every BaseTestGenerator subclass, and all 247 test classes in web/pgadmin declare it as a plain scenarios = [...], with none using ClassVar; the project doesn't run Ruff either, so annotating just this one would make it the odd one out without satisfying any check we actually use.

@dpage, the repository check confirms that AllowedPrivsJsonPathTestCase uses the same plain scenarios declaration as nearby tests. My earlier statement that I could not verify the file was premature. The ClassVar suggestion was unnecessary, and I withdraw it. No change is needed.

You are interacting with an AI system.

allowed_privs.json for the 17_plus bucket lived directly under the
bucket directory instead of under a sql/ subdirectory like every
other bucket (including default), so render_template() looked for
views/pg/17_plus/sql/allowed_privs.json, didn't find it, and silently
fell back to the default bucket's list - which predates MAINTAIN and
lacks 'm'. Moved the four affected files (views/mviews x pg/ppas) to
match the default bucket's layout.

Closes pgadmin-org#10350
Now that allowed_acls for views/mviews correctly includes MAINTAIN on
PG17+, granting the same non-MAINTAIN privilege set as before no
longer equals the full allowed set, so the generated SQL expands to
the explicit privilege list instead of collapsing to "GRANT ALL" -
this is the correct new behaviour, but it left the two mview msql
fixtures (which fell back to the default bucket, written before
MAINTAIN existed) stale. Added 17_plus overrides with the corrected
expected output, alongside the existing 15_plus/16_plus buckets for
these fixtures.
The 17_plus test directories added for the msql fixtures contained only
.sql files, and get_test_folder() in the RE-SQL runner resolves at folder
level rather than per file, unlike get_test_file(): it picks the first
existing version directory and then lists the .json scenario files in it.
On a PG17+ server the runner therefore resolved to a directory with no
JSON in it and ran no view or materialised view scenarios at all, which
is why the stale expected SQL below went unnoticed. Each bucket carries
its own copy of tests.json and test_mview.json for that reason, so the
17_plus buckets now do too.

With the scenarios running again, the reverse engineered SQL for the two
scenarios that grant the seven-privilege set to PUBLIC needs the same
17_plus treatment as the msql fixtures, since sql() re-filters through
parse_priv_to_db() with the version's allowed ACLs and no longer
collapses seven of eight privileges to ALL. The owner's grant still
collapses, as the owner holds MAINTAIN as well.

Verified against PostgreSQL 18: 43 scenarios now run, where none ran
before, and all pass.

98-129: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Add a PG17+ scenario that grants MAINTAIN ('m') through the full GRANT path.

Issue #10350 reports that _parse_privileges drops 'm' when it builds the GRANT statement. test_allowed_privs_json_path.py only checks that 'm' is in the loaded allowed_acls list. No scenario in this file or in pg/17_plus/test_mview.json sends privilege_type: "m", so no test checks that the generated SQL contains MAINTAIN. Add one view scenario and one materialized-view scenario that grant 'm'. Their expected msql should contain GRANT MAINTAIN ... or the explicit privilege list that includes MAINTAIN. If the allowed_privs.json lookup breaks again in another way, these scenarios will catch it where the user sees it.
