Copilot AI commented Feb 19, 2026

The extension hardcoded action=history blocking for anonymous users. This adds $wgCrawlerProtectedActions configuration to make it customizable.

Changes

  • Configuration (extension.json): Added $wgCrawlerProtectedActions with default ["history"] to maintain backward compatibility
  • Hook logic (includes/Hooks.php): Replaced $action === 'history' with in_array( $action, $protectedActions, true ) using config from MediaWikiServices
  • Documentation (README.md): Documented the new configuration option with usage examples
  • Tests: Added tests for configurable action blocking behavior

Usage

// Allow anonymous history access
$wgCrawlerProtectedActions = [];

// Protect multiple actions
$wgCrawlerProtectedActions = [ 'history', 'edit', 'delete' ];

Default value ["history"] preserves existing behavior.

<issue_title>[Feature Request] Make anonymous action=history restriction configurable</issue_title>
<issue_description>It would be nice if this extension were a bit more configurable. For our particular use case, specifically allowing for anonymous use of action=history requests would be helpful, e.g. a Boolean $wgCrawlerAllowHistory or something to that effect.


Added by @jeffw16:

Instructions for Copilot: Please add $wgCrawlerProtectedActions with the default value of ["history"] which replaces the hardcoded check $action === 'history' in includes/Hook.php's onMediaWikiPerformAction hook.

Pull request overview

Adds a new extension configuration option to make which action= requests are blocked for anonymous users configurable (previously hardcoded to action=history).

Changes:

  • Introduces CrawlerProtectedActions config (default ["history"]) to preserve existing behavior.
  • Updates the MediaWikiPerformAction hook to consult config and block configured actions for anonymous users.
  • Documents the new option and adds/updates unit tests and test stubs.

Same issue as above: the getVal() mock map includes a null default parameter, but the code under test calls getVal( 'action' ) with one argument. As written, this will likely return null and not test the intended behavior.

Suggested change
[ 'action', null, 'history' ],
[ 'action', 'history' ],

These history-action tests are skipped whenever the real MediaWikiServices is present, but Hooks::onMediaWikiPerformAction() now always uses MediaWikiServices::getInstance()->getMainConfig(), and the other onMediaWikiPerformAction tests in this file are not skipped. This skip will unnecessarily drop coverage in a real MediaWiki test run; consider removing it (or only skipping when CrawlerProtectedActions cannot be read).

namespaced-stubs.php hardcodes CrawlerProtectedActions to [ 'history' ], which makes it impossible to unit-test the new configurability (e.g., verifying that an empty array allows action=history, or that another action can be protected). Consider making this stub value controllable (e.g., via a static property) so tests can cover non-default configurations.

The README says setting $wgCrawlerProtectedActions = [] will "allow all actions for anonymous users", but anonymous users will still be blocked by the other checks in onMediaWikiPerformAction (type=revision, diff, oldid). Consider rewording to clarify that this only disables the action=-based restriction.

Suggested change
Set to an empty array `[]` to allow all actions for anonymous users.

CrawlerProtectedActions is now configurable, but there are no tests covering non-default configuration values (e.g. empty array allowing action=history, or protecting an additional action). Adding such cases would ensure the new config wiring is actually exercised and remains stable across MediaWiki versions.

The getVal() mocks use willReturnMap entries with two parameters ([ 'action', null, 'history' ]), but Hooks::onMediaWikiPerformAction() calls $request->getVal( 'action' ) with a single argument. That means the map entry won’t match and the mock will return null, so this test won’t actually exercise the history-action branch. Update the mock to match the one-arg call (or provide map entries for both 1-arg and 2-arg invocations).
