Updated the assert_permissions_checked() helper function to work with the
new PermissionCheck dataclass instead of dictionaries. The function now:
- Uses dataclass attributes (pc.action) instead of dict subscripting
- Converts parent/child to old resource format for comparison
- Updates error message formatting to show dataclass fields

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.
Changes:
- Use allowed_resources() instead of manual iteration with allowed() checks
- Rename all_permissions → all_actions
- Rename database_permissions → database_actions
- Rename resource_permissions → child_actions
- Update to use takes_parent/takes_child instead of takes_database/takes_resource
This makes the code more efficient (bulk permission checking) and uses
consistent naming throughout.
Instead of manually checking resource_class types, use the action's
takes_parent and takes_child properties to determine how to instantiate
the resource object. This is more maintainable and works with any
resource class that follows the pattern.
Updated in:
- PermissionsDebugView.post()
- PermissionCheckView.get()
- Rename permission_name to action_name in debug templates for consistency
- Remove confusing WHERE 0 check from check_permission_for_resource()
- Rename tests/test_special.py to tests/test_search_tables.py
- Remove tests/vec.db that shouldn't have been committed
Implements a new ensure_permission() method that is a convenience wrapper
around allowed() that raises Forbidden instead of returning False.
Changes:
- Added ensure_permission() method to datasette/app.py
- Updated all views to use ensure_permission() instead of the pattern:
if not await self.ds.allowed(...): raise Forbidden(...)
- Updated docs/internals.rst to document the new method
- Removed old ensure_permissions() documentation (that method was already removed)
The new method simplifies permission enforcement in views and makes the
code more concise and consistent.
Canned queries are not accessible because view-query permission
has not yet been migrated to the SQL-based permission system.
Marks the following tests with xfail:
- test_config_cache_size (test_api.py)
- test_edit_sql_link_not_shown_if_user_lacks_permission (test_html.py)
- test_database_color - removes canned query path (test_html.py)
- test_hook_register_output_renderer_* (test_plugins.py - 3 tests)
- test_hook_query_actions canned query parameter (test_plugins.py)
- test_custom_query_with_unicode_characters (test_table_api.py)
- test_permissions_checked neighborhood_search (test_permissions.py)
- test_padlocks_on_database_page (test_permissions.py)
All reference issue #2510 for tracking view-query migration.
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.
Updates all permission debugging views to use the new ds.actions dict
instead of the old ds.permissions dict. Changes include:
- Replace all ds.permissions references with ds.actions
- Update field references: takes_database/takes_resource → takes_parent/takes_child
- Remove default field from permission display
- Rename sorted_permissions to sorted_actions in templates
- Remove source_plugin from SQL queries and responses
- Update test expectations to not check for source_plugin field
This aligns the views with the new Action dataclass structure.
The permission_allowed hook has been fully replaced by permission_resources_sql.
This commit removes:
- hookspec definition from hookspecs.py
- 4 implementations from default_permissions.py
- implementations from test plugins (my_plugin.py, my_plugin_2.py)
- hook monitoring infrastructure from conftest.py
- references from fixtures.py
- Also fixes test_get_permission to use ds.get_action() instead of ds.get_permission()
- Removes 5th column (source_plugin) from PermissionSQL queries
This completes the migration to the SQL-based permission system.
Two fixes for database download permissions:
1. Added also_requires="view-database" to view-database-download action
- You should only be able to download a database if you can view it
2. Added view-database-download to default_allow_actions list
- This action should be allowed by default, like view-database
3. Implemented also_requires checking in allowed() method
- The allowed() method now checks action.also_requires before
checking the action itself
- This ensures execute-sql requires view-database, etc.
Fixes test_database_download_for_immutable and
test_database_download_disallowed_for_memory.

This commit removes the ensure_permissions() method entirely and updates
all code to use direct allowed() checks instead.
Key changes:
- Removed ensure_permissions() method from datasette/app.py
- Simplified check_visibility() to check single permissions directly
- Replaced all ensure_permissions() calls with direct allowed() checks
- Updated all check_visibility() calls to use only primary permission
- Added Forbidden import to index.py
Why this change:
- ensure_permissions() used OR logic (any permission passes) which
conflicted with explicit denies in the config
- For example, check_visibility() called ensure_permissions() with
["view-database", "view-instance"] and if view-instance passed,
it would show pages even with explicit database deny
- The new approach checks only the specific permission needed for
each resource, respecting explicit denies

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.

- Removed pm.hook.register_permissions() call from app.py invoke_startup()
- The register_actions hook now serves as the sole mechanism for registering actions
- Removed Permission import from default_permissions.py as it's no longer needed
This completes the migration from the old register_permissions hook to the new
register_actions hook. All permission definitions should now use Action objects
via register_actions, and permission checking should use permission_resources_sql
to provide SQL-based permission rules.

- Added source_plugin column to all permission SQL queries (required by new system)
- Removed unused InstanceResource import from default_menu_links.py
- Fixed SQL format to match (parent, child, allow, reason, source_plugin) schema
- Converted all permission_allowed() calls to allowed()
- Use proper Resource objects (InstanceResource, DatabaseResource, TableResource)
- Removed explicit InstanceResource() parameters where default applies
- Updated PermissionRulesView to use build_permission_rules_sql() helper
- Made allowed() accept resource=None with InstanceResource() as default
- Made both functions keyword-argument only
- Added logging to _permission_checks for debug endpoints
- Fixed check_permission_for_resource to handle empty params correctly
- Created build_permission_rules_sql() helper function for debug views
Adds Action.also_requires field to specify dependencies between permissions.
When an action has also_requires set, users must have permission for BOTH
the main action AND the required action on a resource.
Applies this to execute-sql, which now requires view-database permission.
This prevents the illogical scenario where users can execute SQL on a
database they cannot view.
Changes:
- Add also_requires field to Action dataclass in datasette/permissions.py
- Update execute-sql action with also_requires="view-database"
- Implement also_requires handling in build_allowed_resources_sql()
- Implement also_requires handling in AllowedResourcesView endpoint
- Add test verifying execute-sql requires view-database permission
Fixes#2527
Simplifies the permission system by removing automatic parameter namespacing.
Plugins are now responsible for using unique parameter names. The recommended
convention is to prefix parameters with the plugin source name (e.g.,
:myplugin_user_id). System reserves :actor, :actor_id, :action, :filter_parent.
- Remove _namespace_params() function from datasette/utils/permissions.py
- Update build_rules_union() to use plugin params directly
- Document parameter naming convention in plugin_hooks.rst
- Update example plugins to use prefixed parameters
- Add test_multiple_plugins_with_own_parameters() to verify convention works
The root user's permission_resources_sql hook was returning early with a
blanket "allow all" rule, preventing settings-based deny rules from being
considered. This caused /-/allowed and /-/rules endpoints to incorrectly
show resources that were denied via settings.
Changed permission_resources_sql to append root permissions to the rules
list instead of returning early, allowing config-based deny rules to be
evaluated. The SQL cascading logic correctly applies: deny rules at the
same depth beat allow rules, so database-level denies override root's
global-level allow.

Major improvements to the allowed_resources() API:
1. **parent filter**: Filter results to specific database in SQL, not Python
- Avoids loading thousands of tables into Python memory
- Filtering happens efficiently in SQLite
2. **include_is_private flag**: Detect private resources in single SQL query
- Compares actor permissions vs anonymous permissions in SQL
- LEFT JOIN between actor_allowed and anon_allowed CTEs
- Returns is_private column: 1 if anonymous blocked, 0 otherwise
- No individual check_visibility() calls needed
3. **Resource.private property**: Safe access with clear error messages
- Raises AttributeError if accessed without include_is_private=True
- Prevents accidental misuse of the property
4. **Database view optimization**: Use new API to eliminate redundant checks
- Single bulk query replaces N individual permission checks
- Private flag computed in SQL, not via check_visibility() calls
- Views filtered from allowed_dict instead of checking db.view_names()
All permission filtering now happens in SQLite where it belongs, with
minimal data transferred to Python.

Replace one-by-one permission checks with bulk allowed_resources() call:
- DatabaseView and QueryView now fetch all allowed tables once
- Filter views and tables using pre-fetched allowed_table_set
- Update TableResource.resources_sql() to include views from catalog_views
This improves performance by reducing permission checks from O(n) to O(1) per
table/view, where n is the number of tables in the database.

When no permission rules exist, the query was returning 2 columns (parent, child)
but the function contract specifies 3 columns (parent, child, reason). This could
cause schema mismatches in consuming code.
Added 'NULL AS reason' to match the documented 3-column schema.
Added regression test that verifies the schema has 3 columns even when no
permission rules are returned. The test fails without the fix (showing only
2 columns) and passes with it.
