What this is

If a Query Tool result set includes a calculated or aliased column (e.g. first_name || ' ' || last_name AS the_name), editing any cell on an existing row and saving throws column "the_name" does not exist. The frontend already marks such columns non-editable (shown with a lock icon), but save_changed_data()'s update path still passed them through when rendering the UPDATE statement.

The insert path already had this guard, added for #9939; the update path just never got the equivalent filter.

Fix

save_changed_data() now drops any key not present in columns_info, or explicitly marked is_editable: False, before rendering the UPDATE, in both the insert and update code paths.

Fixes #10103.

Test plan

  • Added TestSaveUpdatedRowSkipsNonEditableColumn, mirroring the existing insert-path test for Query Editor Cannot Recognize Non-Updatable Fields #9939.
  • regression/runtests.py --pkg tools.sqleditor.utils.tests.test_save_changed_data — 14/14 passed.
  • regression/runtests.py --pkg tools.sqleditor — 158 passed, 3 pre-existing/unrelated skips.
  • pycodestyle clean.

…-org#10214)

The annotation conditions referenced the non-existent top-level
.Values.existingSecret instead of .Values.auth.existingSecret, so the
secret checksum annotation and the empty-secret gating never worked as
intended when an existing secret wasn't supplied.
…rg#10251)

CONCURRENTLY was being appended to the parenthesised option list
alongside VERBOSE etc., which PostgreSQL rejects. It's not a
parenthesizable option: it belongs standalone, between the object
type keyword and the object name.
…min-org#9450)

A role's membership tab only enabled the add/remove member controls
for superusers and CREATEROLE holders, so a user who was themselves
granted ADMIN OPTION on that role (and can therefore GRANT/REVOKE its
membership at the SQL level) had no way to add other members, and hit
a permission error server-side if they tried anyway.

The role UI schema now also allows membership changes when the
current user is a member of the role with admin=true. The backend
mirrors this: permission.sql reports whether the connecting user
holds ADMIN OPTION on the target role, and the update handler lets
such a request through only when it's restricted to rolmembers
changes, so this can't be used to escalate other role attributes.
…in-org#10309)

validate_json_data() only checked that the Username key was present on
a non-shared server, not that it held anything useful, so an empty or
null value imported cleanly and left behind a server that libpq would
silently authenticate as the OS account running pgAdmin rather than
reject outright. Check the value, matching the truthiness check already
used for shared servers and the "Username must be specified" rule
enforced by the server dialog.
…mode (pgadmin-org#8991)

execute_void() blindly reused whatever cursor was cached for the
connection, which under "server cursor" mode is the named/server-side
AsyncDictServerCursor left over from the last SELECT. A named cursor's
execute() always wraps the statement as `DECLARE ... CURSOR FOR
<query>`, which cannot express a transaction-control statement, so
BEGIN/COMMIT/ROLLBACK silently failed (failing one step earlier still,
on a `prepare` keyword the server-side cursor's execute() doesn't
accept at all) and the exception was swallowed by the background query
thread. The transaction was therefore never actually committed or
rolled back, and the next poll() picked up the previous query's
leftover column info, which is what made the result grid appear
instead of the Messages tab.

Run the statement through a throwaway plain cursor instead, leaving
the cached server-side cursor untouched, and clear the stale column
info so poll() correctly reports no result set.

Review Change Stack

Walkthrough

Changes

Role membership permissions

Layer / File(s) Summary
ADMIN OPTION permission contract
web/pgadmin/browser/server_groups/servers/roles/__init__.py, web/pgadmin/browser/server_groups/servers/roles/templates/roles/sql/default/permission.sql
Role permission queries return has_admin_option, and authorization loads this value before checking permissions.
Membership-only update enforcement
web/pgadmin/browser/server_groups/servers/roles/__init__.py, web/pgadmin/browser/server_groups/servers/roles/tests/test_role_check_permission_unit_test.py
Users with ADMIN OPTION can update rolmembers; other updates remain forbidden. Tests cover ordinary users, ADMIN OPTION users, role drops, and superusers.
Membership editing controls
web/pgadmin/browser/server_groups/servers/roles/static/js/role.ui.js, web/regression/javascript/schema_ui_files/role.ui.spec.js
The role UI allows membership changes for ADMIN OPTION users and retains read-only behavior for other users.

Concurrent REINDEX SQL

Layer / File(s) Summary
REINDEX command generation and expectations
web/pgadmin/tools/maintenance/templates/maintenance/sql/command.sql, web/pgadmin/tools/maintenance/tests/test_maintenance_create_job_unit_test.py
REINDEX statements now place CONCURRENTLY after the target object type. Tests update database, table, and index expectations.

Query result update filtering

Layer / File(s) Summary
Editable column filtering
web/pgadmin/tools/sqleditor/utils/save_changed_data.py, web/pgadmin/tools/sqleditor/utils/tests/test_save_changed_data.py
Update SQL excludes unknown and non-editable columns. Regression coverage verifies that aliased expression columns are not updated.

Server validation and cursor execution

Layer / File(s) Summary
Non-shared username validation
web/pgadmin/utils/__init__.py, web/pgadmin/utils/tests/test_validate_json_data.py
Non-shared servers reject empty or null Username values.
Transaction control with server cursors
web/pgadmin/utils/driver/psycopg3/connection.py, web/pgadmin/utils/driver/psycopg3/tests/test_execute_void_server_cursor.py
execute_void uses a temporary plain cursor for COMMIT and ROLLBACK when a server cursor is cached, then clears stale result state.

Helm authentication secret references

Layer / File(s) Summary
Authentication secret conditions
pkg/helm/templates/deployment.yaml
Deployment annotations and secret checksum conditions now use .Values.auth.existingSecret.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to 767c8

This change set currently includes unresolved failures that can reject valid role updates, return stale query results after void operations, and allow invalid server-import data to persist; it also permits unsupported reindex flag combinations to silently change behavior, so it is not merge-ready until these issues are fixed or explicitly accepted.

Check the original request fields before validation mutates the request.

@validate_request runs before update. _validate_rolemembers adds rol_members_list and related derived keys to self.request. A valid request that contains only rolmembers then fails this subset check and returns 403.

Store the client-supplied field names before validation. Use that stored set for the membership-only restriction. Add a regression test that executes the decorated update path with a rolmembers-only payload.

     if request.data:
         data = json.loads(request.data)

Reject the unsupported flag combination on the server. validate_maintenance_data accepts both flags, and a direct request reaches the template even though the UI clears reindex_concurrently. The template then silently emits non-concurrent REINDEX SYSTEM.

Reject validation errors for regular imports.

load_database_servers() defaults from_setup to False, and the regular import caller uses that default. Therefore, an empty or null Username can pass validation and persist through new_server.username. Handle error_msg regardless of from_setup, and add a non-setup integration test.

Keep poll() on the void-operation cursor.

execute_void() replaces only its local cursor, so self.__async_cursor still points to the previous server-side cursor. The next poll() can return the previous result set and metadata. Store the throwaway plain cursor in self.__async_cursor, or add explicit no-result handling in poll(). Extend web/pgadmin/utils/driver/psycopg3/tests/test_execute_void_server_cursor.py to seed the private cursor, call poll(), and assert that the previous columns and rows are not returned.
