Actor restrictions (_r) now integrate with the SQL permission layer via
the permission_resources_sql() hook instead of acting as a post-filter.
This fixes the issue where allowed_resources() didn't respect restrictions,
causing incorrect database/table listings at /.json and /database.json
endpoints for restricted actors.
Key changes:
- Add _restriction_permission_rules() function to generate SQL rules from _r
- Restrictions create global DENY + specific ALLOW rules using allowlist
- Restrictions act as gating filter BEFORE config/root/default permissions
- Remove post-filter check from allowed() method (now redundant)
- Skip default allow rules when actor has restrictions
- Add comprehensive tests for restriction filtering behavior
The cascading permission logic (child → parent → global) ensures that
allowlisted resources override the global deny, while non-allowlisted
resources are blocked.
Closes#2534
Updated test expectations to match the actual /-/permissions POST endpoint:
1. **Resource format**: Changed from empty list `[]` to `None` when no resources,
and from tuple `(a, b)` to list `[a, b]` for two resources (JSON serialization)
2. **Result values**: Changed from sentinel "USE_DEFAULT" to actual boolean True/False
3. **also_requires dependencies**: Fixed tests for actions with dependencies:
- view-database-download now requires both "vdd" and "vd" in restrictions
- execute-sql now requires both "es" and "vd" in restrictions
4. **No upward cascading**: view-database does NOT grant view-instance
(changed expected result from True to False)
All 20 test_actor_restricted_permissions test cases now pass.

These tests were expecting an old API behavior from the /-/permissions debug endpoint
that no longer exists. The tests expect:
- A "default" field in the response (removed when migrating to new permission system)
- "USE_DEFAULT" sentinel values instead of actual True/False results
- Empty list `[]` for no resource instead of `None`
The /-/permissions POST endpoint was updated (views/special.py:151-185) to return
simpler responses without the "default" field, but these tests weren't updated to match.
These tests need to be rewritten to test the new permission system correctly.
Refs #2534
The test was expecting upward permission cascading (e.g., view-table permission
granting view-database access), but the actual implementation in
restrictions_allow_action() uses exact-match, non-cascading checks.
Updated 5 test cases to expect 403 (Forbidden) instead of 200 when:
- Actor has view-database permission but accesses instance page
- Actor has database-level view-table permission but accesses instance/database pages
- Actor has table-level view-table permission but accesses instance/database pages
This matches the documented behavior: "Restrictions work on an exact-match basis:
if an actor has view-table permission, they can view tables, but NOT automatically
view-instance or view-database."

This change integrates canned queries with Datasette's new SQL-based
permissions system by making the following changes:
1. **Default canned_queries plugin hook**: Added a new hookimpl in
default_permissions.py that returns canned queries from datasette
configuration. This extracts config-reading logic into a plugin hook,
allowing QueryResource to discover all queries.
2. **Async resources_sql()**: Converted Resource.resources_sql() from a
synchronous class method returning a string to an async method that
receives the datasette instance. This allows QueryResource to call
plugin hooks and query the database.
3. **QueryResource implementation**: Implemented QueryResource.resources_sql()
to gather all canned queries by:
- Querying catalog_databases for all databases
- Calling canned_queries hooks for each database with actor=None
- Building a UNION ALL SQL query of all (database, query_name) pairs
- Properly escaping single quotes in resource names
4. **Simplified get_canned_queries()**: Removed config-reading logic since
it's now handled by the default plugin hook.
5. **Added view-query to default allow**: Added "view-query" to the
default_allow_actions set so canned queries are accessible by default.
6. **Removed xfail markers**: Removed test xfail markers from:
- tests/test_canned_queries.py (entire module)
- tests/test_html.py (2 tests)
- tests/test_permissions.py (1 test)
- tests/test_plugins.py (1 test)
All canned query tests now pass with the new permission system.

Instead of logging permission checks as dicts with a 'resource' key,
use a typed dataclass with separate parent and child fields.
Changes:
- Created PermissionCheck dataclass in app.py
- Updated permission check logging to use dataclass
- Updated PermissionsDebugView to use dataclass attributes
- Updated PermissionCheckView to check parent/child instead of resource
- Updated permissions_debug.html template to display parent/child
- Updated test expectations to use dataclass attributes
This provides better type safety and cleaner separation between
parent and child resource identifiers.
The new SQL-based permission system always resolves to True or False,
so the concept of "used default" (tracking when no hook had an opinion)
is no longer relevant. Removes:
- used_default from permission check logging in app.py
- used_default from permission debug responses in special.py
- used_default display from permissions_debug.html template
- used_default from test expectations in test_permissions.py
This simplifies the permission system by eliminating the "no opinion" state.
This test creates tokens with actor restrictions (_r) which need
additional work to properly integrate with the new permission system.

Actor restrictions (_r in actor dict) need additional work to properly
integrate with the new SQL-based permission system. Marking these tests
as expected to fail until that work is completed.
Tests marked as xfail:
- test_actor_restricted_permissions (20 test cases)
- test_actor_restrictions (5 specific parameter combinations)
Test improvements: 37 failures → 12 failures

Changes:
- Fixed expand_foreign_keys() to use new check_visibility() signature
without the 'permissions' keyword argument
- Removed 'default' parameter from allowed() call in filters.py
- Marked view-query tests as xfail since view-query permission is not yet
migrated to the new SQL-based permission system
Test improvements: 41 failures → 37 failures

Simplified restrictions_allow_action() to work on exact-match basis only.
Actor restrictions no longer use permission implication logic - if an actor
has view-table permission, they can view tables but NOT automatically
view-instance or view-database.
Updated test_restrictions_allow_action test cases to reflect new behavior:
- Removed test cases expecting view-table to imply view-instance
- Removed test cases expecting view-database to imply view-instance
- Removed test cases expecting execute-sql to imply view-instance/view-database
- Added test cases verifying exact matches work correctly
- Added test case verifying abbreviations work (es -> execute-sql)
This aligns actor restrictions with the new permission model where each
action is checked independently without hierarchical implications.

The bridge was incorrectly using the new allowed() method which applies
default allow rules. This caused actors without restrictions to get True
instead of USE_DEFAULT, breaking backward compatibility.
Fixed by:
- Removing the code that converted to resource objects and called allowed()
- Bridge now ONLY checks config-based rules via _config_permission_rules()
- Returns None when no config rules exist, allowing Permission.default to apply
- This maintains backward compatibility with the permission_allowed() API
All 177 permission tests now pass, including test_actor_restricted_permissions
and test_permissions_checked which were previously failing.
The test expects ensure_permissions() to check all three permissions
(view-database-download, view-database, view-instance) but the current
implementation short-circuits after the first successful check.
Created issue #2526 to track the investigation of the expected behavior.

New mechanism for restricting permissions further for a given actor.
This still needs documentation. It will eventually be used by the mechanism to issue
signed API tokens that are only able to perform a subset of actions.
This also adds tests that exercise the POST /-/permissions tool, refs #1881
