LocalRepo::cleanupBatch | ( | array | $files, |
$flags = 0 ) |
Deletes a batch of files.
Each file can be a (zone, rel) pair, virtual url, storage path. It will try to delete each file, but ignores any errors that may occur.
array | $files | List of files to delete |
int | $flags | Bitwise combination of the following flags: self::SKIP_LOCKING Skip any file locking when doing the deletions |

LocalRepo::cleanupDeletedBatch | ( | array | $storageKeys | ) |
Delete files in the deleted directory if they are not referenced in the filearchive table.
This needs to be done in the repo because it needs to interleave database locks with file operations, which is potentially a remote operation.

LocalRepo::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
mixed | $srcRel | Relative path for the file to be deleted |
mixed | $archiveRel | Relative path for the archive location. Relative to a private archive directory. |

LocalRepo::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.
array | $sourceDestPairs | Array 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. |
