view-query is back in the default allow actions now. We have
other mechanisms that work for controlling visibility, and
the fact that queries default to running with the permissions
of the actor makes this safe.
`datasette.client.get(path, actor={"id": "root"}` now makes the internal request with that actor as `request.actor` - same for the other HTTP verb methods on `datasette.client`.
Upgraded relevant tests to use the new `actor=` mechanism.
- New CSRF protection middleware inspired by Go 1.25 and research by Filippo Valsorda - https://words.filippo.io/csrf/ - this replaces the old CSRF token based protection.
- Removes all instances of `<input type="hidden" name="csrftoken" value="{{ csrftoken() }}">` in the templates - they are no longer needed.
- Removes the `def skip_csrf(datasette, scope):` plugin hook defined in `datasette/hookspecs.py` and its documentation and tests.
- Updated CSRF protection documentation to describe the new approach.
- Upgrade guide now describes the CSRF change.
Closes#2649
* Add register_token_handler plugin hook for pluggable token backends
Adds a new register_token_handler hook that allows plugins to provide
custom token creation and verification backends. This enables plugins
like datasette-oauth to issue tokens without depending on specific
backend plugins like datasette-auth-tokens.
Key changes:
- New datasette/tokens.py with TokenHandler base class and SignedTokenHandler
(the default signed-token implementation moved here)
- New register_token_handler hookspec in hookspecs.py
- Datasette.create_token() is now async and delegates to token handlers
- New Datasette.verify_token() method tries all handlers in sequence
- handler= parameter on create_token() to select a specific backend
- TokenHandler exported from datasette package for plugin use
- Fixed actor_from_request loop to await all coroutines (avoids warnings)
* Add documentation and hook test for register_token_handler
Fixes CI failures: the new hook needs a section in docs/plugin_hooks.rst
(checked by test_plugin_hooks_are_documented) and a test_hook_* function
in test_plugins.py (checked by test_plugin_hooks_have_tests).
* Register tokens module as separate default plugin
Instead of re-exporting hookimpls from default_permissions/__init__.py,
register datasette.default_permissions.tokens as its own DEFAULT_PLUGINS
entry. Cleaner and avoids confusing import-for-side-effect patterns.
* Replace restrict_x params with TokenRestrictions dataclass
Consolidates the three separate restrict_all, restrict_database, and
restrict_resource parameters into a single TokenRestrictions dataclass.
Cleaner API surface for both Datasette.create_token() and
TokenHandler.create_token().
Also clarifies docs re: default handler selection via pluggy ordering.
* Add builder methods to TokenRestrictions
Adds allow_all(), allow_database(), and allow_resource() methods that
return self for chaining. Callers no longer need to manipulate nested
dicts directly:
restrictions = (TokenRestrictions()
.allow_all("view-instance")
.allow_database("mydb", "create-table")
.allow_resource("mydb", "mytable", "insert-row"))
* docs: add 1.0a25 upgrade guide section for create_token() signature change
Ref: https://github.com/simonw/datasette/issues/2649#issuecomment-3962639393
* docs: note that create_token() is now async in upgrade guide
* docs: update internals, plugin_hooks, authentication for new token API
- internals.rst: new async create_token() signature with restrictions
and handler params, add TokenRestrictions reference docs
- plugin_hooks.rst: show full create_token signature in TokenHandler
example, note list returns and error cases
- authentication.rst: cross-reference TokenRestrictions from the
restrictions section
* style: apply black formatting to token handler files
* docs: fix RST heading underline length in internals.rst
* tests: add restrictions round-trip and expiration tests for token handler
Covers allow_database/allow_resource builders, _r payload encoding,
and token_expires in verified actors. Coverage 76% -> 90%.
* tests: add test for signed tokens disabled
* fix: add TokenRestrictions TYPE_CHECKING import to fix ruff F821
* docs: regenerate plugins.rst with cog
* docs: reformat code blocks in plugin_hooks.rst with blacken-docs
* docs: add await .verify_token() to internals.rst
* tests: rewrite register_token_handler test to use real plugin handler
Adds a HardcodedTokenHandler to the test plugins dir that creates
tokens like dstok_hardcoded_token_1. The test now exercises creating
tokens via the default handler (which is the plugin's hardcoded one),
by explicitly naming the hardcoded handler, and by explicitly naming
the signed handler -- then verifies each token round-trips correctly.
* tests: clarify test_token_handler_via_http tests the default signed handler
* fix: use handler="signed" explicitly where signed tokens are expected
The HardcodedTokenHandler in my_plugin.py gets globally registered,
so create_token() without a handler name picks it up as the default.
Fix the create-token view, CLI, and tests to explicitly request the
signed handler where they depend on signed token behavior.
* fix: use handler="signed" in test_create_table_permissions
https://claude.ai/code/session_013cQFiDQjYRrRBH2biFfKuS
* Split default_permissions.py into a package, refs #2602
* Remove unused is_resource_allowed() method, improve test coverage
- Remove dead code: is_resource_allowed() method was never called
- Change isinstance check to assertion with error message
- Add test cases for table-level restrictions in restrictions_allow_action()
- Coverage for restrictions.py improved from 79% to 99%

* Additional permission test for gap spotted by coverage
* Add keyset pagination to allowed_resources()
This replaces the unbounded list return with PaginatedResources,
which supports efficient keyset pagination for handling thousands
of resources.
Closes#2560
Changes:
- allowed_resources() now returns PaginatedResources instead of list
- Added limit (1-1000, default 100) and next (keyset token) parameters
- Added include_reasons parameter (replaces allowed_resources_with_reasons)
- Removed allowed_resources_with_reasons() method entirely
- PaginatedResources.all() async generator for automatic pagination
- Uses tilde-encoding for tokens (matching table pagination)
- Updated all callers to use .resources accessor
- Updated documentation with new API and examples
The PaginatedResources object has:
- resources: List of Resource objects for current page
- next: Token for next page (None if no more results)
- all(): Async generator that yields all resources across pages
Example usage:
page = await ds.allowed_resources("view-table", actor, limit=100)
for table in page.resources:
print(table.child)
# Iterate all pages automatically
async for table in page.all():
print(table.child)

The /-/check endpoint now requires the permissions-debug permission
to access. This prevents unauthorized users from probing the permission
system. Administrators can grant this permission to specific users or
anonymous users if they want to allow open access.
Added test to verify anonymous and regular users are denied access,
while root user (who has all permissions) can access the endpoint.
Closes#2546
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.

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.
* `asyncio_default_fixture_loop_scope = function`
* Fix a bunch of BeautifulSoup deprecation warnings
* Fix for PytestUnraisableExceptionWarning: Exception ignored in: <_io.FileIO [closed]>
