FileManager for … ?

class DIRAC.DataManagementSystem.DB.FileCatalogComponents.FileManager.FileManagerPs.FileManagerPs(database=None)

Bases: FileManagerBase

__init__(database=None)
addFile(lfns, credDict, connection=False)

Add files to the catalog

Parameters:

lfns (dict) – dict{ lfn : info}. ‘info’ is a dict containing PFN, SE, Size and Checksum the SE parameter can be a list if we have several replicas to register

addFileAncestors(lfns, connection=False)

Add file ancestors to the catalog

addReplica(lfns, connection=False)

Add replica to the catalog

changeFileGroup(lfns)

Get set the group for the supplied files

Parameters:

  • lfns – dictionary < lfn : group >

  • newGroup (int/str) – optional new group/groupID the same for all the supplied lfns

changeFileMode(lfns)

“ Set the mode for the supplied files

Parameters:

  • lfns – dictionary < lfn : mode >

  • newMode (int) – optional new mode the same for all the supplied lfns

changeFileOwner(lfns)

Set the owner for the supplied files

Parameters:

  • lfns – dictionary < lfn : owner >

  • newOwner (int/str) – optional new user/userID the same for all the supplied lfns

countFilesInDir(dirId)

Count how many files there is in a given Directory

Parameters:

dirID – directory id

Returns:

S_OK(value) or S_ERROR

exists(lfns, connection=False)

Determine whether a file exists in the catalog

getDirectoryReplicas(dirID, path, allStatus=False, connection=False)

This is defined in the FileManagerBase but it relies on the SEManager to get the SE names. It is good practice in software, but since the SE and Replica tables are bound together in the DB, I might as well resolve the name in the query

Get the replicas for all the Files in the given Directory

Parameters:

  • dirID (int) – ID of the directory

  • path (unused) – useless

  • allStatus (bool) – whether all replicas and file status are considered If False, take the visibleFileStatus and visibleReplicaStatus values from the configuration

getFileAncestors(lfns, depths, connection=False)
getFileCounters(connection=False)

Get a number of counters to verify the sanity of the Files in the catalog

getFileDescendents(lfns, depths, connection=False)
getFileIDsInDirectory(dirID, requestString=False)
Get a list of IDs for all the files stored in given directories or their

subdirectories

Parameters:

  • dirID (int or list[int]) – single directory ID or a list of directory IDs

  • requestString (bool) – if True return result as a SQL SELECT string

Returns:

list of file IDs or SELECT string

getFileMetadata(lfns, connection=False)

Get file metadata from the catalog

getFileSize(lfns, connection=False)

Get file size from the catalog

getFilesInDirectory(dirID, verbose=False, connection=False)
getLFNForGUID(guids, connection=False)

Returns the lfns matching given guids

getPathPermissions(paths, credDict, connection=False)

Get the permissions for the supplied paths

getReplicaCounters(connection=False)

Get a number of counters to verify the sanity of the Replicas in the catalog

getReplicaStatus(lfns, connection=False)

Get replica status from the catalog

getReplicas(lfns, allStatus, connection=False)

Get file replicas from the catalog

getReplicasByMetadata(metaDict, path, allStatus, credDict, connection=False)

Get file replicas for files corresponding to the given metadata

getSEDump(seNames)

Return all the files at a given SE, together with checksum and size

Parameters:

seName – list of StorageElement names

Returns:

S_OK with list of tuples (SEName, lfn, checksum, size)

isFile(lfns, connection=False)

Determine whether a path is a file in the catalog

removeFile(lfns, connection=False)
removeReplica(lfns, connection=False)
