ApiUpload::dieRecoverableError (   $errors,
  $parameter = null 
)
private

Throw an error that the user can recover from by providing a better value for $parameter.

Parameters
array$errorsArray of Message objects, message keys, key+param arrays, or StatusValue::getErrors()-style arrays
string | null$parameterParameter that needs revising
Exceptions
ApiUsageException

Definition at line 363 of file ApiUpload.php.

Referenced by checkVerification(), execute(), and performUpload().

◆ dieStatusWithCode()

ApiUpload::dieStatusWithCode (   $status,
  $overrideCode,
  $moreExtraData = null 
)

Like dieStatus(), but always uses $overrideCode for the error code, unless the code comes from IApiMessage.

Parameters
Status$status
string$overrideCodeError code to use if there isn't one from IApiMessage
array | null$moreExtraData
Exceptions
ApiUsageException

Referenced by getChunkResult(), and selectUploadModule().

◆ execute()

ApiUpload::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.

◆ getAllowedParams()

ApiUpload::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

◆ getApiWarnings()

ApiUpload::getApiWarnings ( )
protected

Check warnings.

Returns a suitable array for inclusion into API results if there were warnings Returns the empty array if there were no warnings

Returns
array

Definition at line 661 of file ApiUpload.php.

Referenced by getChunkResult(), and getContextResult().

◆ getChunkResult()

ApiUpload::getChunkResult (   $warnings)
private

◆ getContextResult()

ApiUpload::getContextResult ( )
private

Get an upload result based on upload context.

Returns
array

◆ getExamplesMessages()

ApiUpload::getExamplesMessages ( )
protected

Returns usage examples for this module.

Return value has query strings as keys, with values being either strings (message key), arrays (message key + parameter), or Message objects.

Do not call this base class implementation when overriding this method.

Since
1.25
Returns
array

Reimplemented from ApiBase.

Definition at line 912 of file ApiUpload.php.

◆ getHelpUrls()

ApiUpload::getHelpUrls ( )

Return links to more detailed help pages about the module.

Since
1.25, returning boolean false is deprecated
Returns
string|array

Reimplemented from ApiBase.

Definition at line 922 of file ApiUpload.php.

◆ getStashResult()

ApiUpload::getStashResult (   $warnings)
private

Get Stash Result, throws an exception if the file could not be stashed.

Parameters
array$warningsArray of Api upload warnings
Returns
array

◆ handleStashException()

Parameters
Exception$e
Returns
StatusValue

Referenced by execute().

◆ isWriteMode()

ApiUpload::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 846 of file ApiUpload.php.

◆ mustBePosted()

ApiUpload::mustBePosted ( )

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

Returns
bool

Reimplemented from ApiBase.

Definition at line 842 of file ApiUpload.php.

◆ needsToken()

ApiUpload::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 908 of file ApiUpload.php.

◆ performStash()

ApiUpload::performStash (   $failureMode,
$data = null 
)
private

Stash the file and add the file key, or error information if it fails, to the data.

Parameters
string$failureModeWhat to do on failure to stash:
  • When 'critical', use dieStatus() to produce an error response and throw an exception. Use this when stashing the file was the primary purpose of the API request.
  • When 'optional', only add a 'stashfailed' key to the data and return null. Use this when some error happened for a non-stash upload and we're stashing the file only to save the client the trouble of re-uploading it.
array&$dataAPI result to which to add the information
Returns
string|null File key

protected

Perform the actual upload.

Returns a suitable result array on success; dies on failure.
