FileRepo::cleanupBatch ( array  $files,

int$flagsBitwise combination of the following flags: self::SKIP_LOCKING Skip any file locking when doing the deletions
Returns
Status

Definition at line 917 of file FileRepo.php.

STUB

Parameters
array$storageKeys

Definition at line 1470 of file FileRepo.php.

References assertWritableRepo().

FileRepo::concatenate ( array  $srcPaths,
  $dstPath,
  $flags = 0 
)

Concatenate a list of temporary files into a target file location.

Parameters
array$srcPathsOrdered list of source virtual URLs/storage paths
string$dstPathTarget file system path
int$flagsBitwise combination of the following flags: self::DELETE_SOURCE Delete the source files on success
Returns
Status

FileRepo::delete (   $srcRel,
  $archiveRel 
)

Move a file to the deletion archive.

If no valid deletion archive exists, this may either delete the file or throw an exception, depending on the preference of the repository

Parameters
mixed$srcRelRelative path for the file to be deleted
mixed$archiveRelRelative path for the archive location. Relative to a private archive directory.
Returns
Status

Definition at line 1388 of file FileRepo.php.

FileRepo::deleteBatch ( array  $sourceDestPairs)

Move a group of files to the deletion archive.

If no valid deletion archive is configured, this may either delete the file or throw an exception, depending on the preference of the repository.

The overwrite policy is determined by the repository – currently LocalRepo assumes a naming scheme in the deleted zone based on content hash, as opposed to the public zone which is assumed to be unique.

Parameters
array$sourceDestPairsArray of source/destination pairs. Each element is a two-element array containing the source file path relative to the public root in the first element, and the archive file path relative to the deleted zone root in the second element.
Exceptions
MWException
Returns

$findItem = [ 'title' => $title, 'private' => true ]; $findBatch = [ $findItem ]; $repo->findFiles( $findBatch );

No title should appear in $items twice, as the result use titles as keys

Parameters
