Detailed Description

Prepare an edit in shared cache so that it can be reused on edit.

This endpoint can be called via AJAX as the user focuses on the edit summary box. By the time of submission, the parse may have already finished, and can be immediately used on page save. Certain parser functions like {{REVISIONID}} or {{CURRENTTIME}} may cause the cache to not be used on edit. Template and files used are check for changes since the output was generated. The cache TTL is also kept low for sanity.

Since
1.25

Member Function Documentation

◆ execute()

ApiStashEdit::execute ( )

Evaluates the parameters, performs the requested query, and sets up the result.

Concrete implementations of ApiBase must override this method to provide whatever functionality their module offers. Implementations must not produce any output on their own and are not expected to handle any errors.

The execute() method will be invoked directly by ApiMain immediately before the result of the module is output. Aside from the constructor, implementations should assume that no other methods will be called externally on the module before the result is processed.

The result data should be stored in the ApiResult object available through getResult().

Reimplemented from ApiBase.

Definition at line 39 of file ApiStashEdit.php.

References $content, $title, ApiBase\dieWithError(), ApiBase\extractRequestParams(), WikiPage\factory(), getContentHandlerFactory(), ApiBase\getModuleName(), ApiBase\getResult(), ApiBase\getTitleOrPageId(), ContextSource\getUser(), ContentHandler\makeContent(), and ApiBase\requireOnlyOneParameter().

◆ getAllowedParams()

ApiStashEdit::getAllowedParams ( )

Returns an array of allowed parameters (parameter name) => (default value) or (parameter name) => (array with PARAM_* constants as keys) Don't call this function directly: use getFinalParams() to allow hooks to modify parameters as needed.

Some derived classes may choose to handle an integer $flags parameter in the overriding methods. Callers of this method can pass zero or more OR-ed flags like GET_VALUES_FOR_HELP.

Returns
array

◆ getContentHandlerFactory()

ApiStashEdit::getContentHandlerFactory ( )
private

Definition at line 222 of file ApiStashEdit.php.

Referenced by execute(), and getAllowedParams().

◆ isInternal()

ApiStashEdit::isInternal ( )

Indicates whether this module is "internal" Internal API modules are not (yet) intended for 3rd party use and may be unstable.

Since
1.25
Returns
bool

Reimplemented from ApiBase.

Definition at line 218 of file ApiStashEdit.php.

◆ isWriteMode()

ApiStashEdit::isWriteMode ( )

Indicates whether this module requires write mode.

This should return true for modules that may require synchronous database writes. Modules that do not need such writes should also not rely on master database access, since only read queries are needed and each master DB is a single point of failure. Additionally, requests that only need replica DBs can be efficiently routed to any datacenter via the Promise-Non-Write-API-Action header.

Returns
bool

Reimplemented from ApiBase.

Definition at line 214 of file ApiStashEdit.php.

◆ mustBePosted()

ApiStashEdit::mustBePosted ( )

Indicates whether this module must be called with a POST request.

Returns
bool

Reimplemented from ApiBase.

Definition at line 210 of file ApiStashEdit.php.

◆ needsToken()

ApiStashEdit::needsToken ( )

Returns the token type this module requires in order to execute.

Modules are strongly encouraged to use the core 'csrf' type unless they have specialized security needs. If the token type is not one of the core types, you must use the ApiQueryTokensRegisterTypes hook to register it.

Returning a non-falsey value here will force the addition of an appropriate 'token' parameter in self::getFinalParams(). Also, self::mustBePosted() must return true when tokens are used.

In previous versions of MediaWiki, true was a valid return value. Returning true will generate errors indicating that the API module needs updating.

Returns
string|false

Reimplemented from ApiBase.

Definition at line 206 of file ApiStashEdit.php.

◆ parseAndStash()

ApiStashEdit::parseAndStash ( WikiPage  $page,
Content  $content,
User  $user,
  $summary 
)
Parameters
WikiPage$page
Content$contentEdit content
User$user
string$summaryEdit summary
Returns
string ApiStashEdit::ERROR_* constant
