This introduces a new hierarchical permission system that uses SQL queries
for efficient permission checking across resources. The system replaces the
older permission_allowed() pattern with a more flexible resource-based
approach.
Core changes:
- New Resource ABC and Action dataclass in datasette/permissions.py
* Resources represent hierarchical entities (instance, database, table)
* Each resource type implements resources_sql() to list all instances
* Actions define operations on resources with cascading rules
- New plugin hook: register_actions(datasette)
* Plugins register actions with their associated resource types
* Replaces register_permissions() and register_resource_types()
* See docs/plugin_hooks.rst for full documentation
- Three new Datasette methods for permission checks:
* allowed_resources(action, actor) - returns list[Resource]
* allowed_resources_with_reasons(action, actor) - for debugging
* allowed(action, resource, actor) - checks single resource
* All use SQL for filtering, never Python iteration
- New /-/tables endpoint (TablesView)
* Returns JSON list of tables user can view
* Supports ?q= parameter for regex filtering
* Format: {"matches": [{"name": "db/table", "url": "/db/table"}]}
* Respects all permission rules from configuration and plugins
- SQL-based permission evaluation (datasette/utils/actions_sql.py)
* Cascading rules: child-level → parent-level → global-level
* DENY beats ALLOW at same specificity
* Uses CTEs for efficient SQL-only filtering
* Combines permission_resources_sql() hook results
- Default actions in datasette/default_actions.py
* InstanceResource, DatabaseResource, TableResource, QueryResource
* Core actions: view-instance, view-database, view-table, etc.
- Fixed default_permissions.py to handle database-level allow blocks
* Now creates parent-level rules for view-table action
* Fixes: datasette ... -s databases.fixtures.allow.id root
Documentation:
- Comprehensive register_actions() hook documentation
- Detailed resources_sql() method explanation
- /-/tables endpoint documentation in docs/introspection.rst
- Deprecated register_permissions() with migration guide
Tests:
- tests/test_actions_sql.py: 7 tests for core permission API
- tests/test_tables_endpoint.py: 13 tests for /-/tables endpoint
- All 118 documentation tests pass
- Tests verify SQL does filtering (not Python)

* Reformat JavaScript files with Prettier
Ran `npm run fix` to apply consistent code formatting across JavaScript
files using the project's Prettier configuration (2 spaces, no tabs).
Files reformatted:
- datasette/static/datasette-manager.js
- datasette/static/json-format-highlight-1.0.1.js

* Upgrade Prettier from 2.2.1 to 3.6.2
Updated package.json and package-lock.json to use Prettier 3.6.2,
ensuring consistent formatting between local development and CI.
The existing JavaScript files are already formatted with Prettier 3.x
style from the previous commit.

Claude Code:
Created DatabaseContext as a documented dataclass following the same pattern
as the existing QueryContext. This change replaces the inline dictionary
context creation with an explicit dataclass that:
- Documents all 21 template context variables with help metadata
- Inherits from the Context base class for identification
- Provides better IDE support and type safety
- Makes template variables discoverable without reading code
Also updated QueryContext to inherit from Context for consistency.
Extracted common JavaScript utilities from debug_allowed.html, debug_check.html, and debug_rules.html into a new _debug_common_functions.html include template. This eliminates code duplication and improves maintainability.
The shared functions include:
- populateFormFromURL(): Populates form fields from URL query parameters
- updateURL(formId, page): Updates browser URL with form values
- escapeHtml(text): HTML escaping utility

* allowed_resources_sql plugin hook and infrastructure
* New methods for checking permissions with the new system
* New /-/allowed and /-/check and /-/rules special endpoints
Still needs to be integrated more deeply into Datasette, especially for listing visible tables.
