class DIRAC.DataManagementSystem.DB.FileCatalogComponents.DirectoryManager.DirectoryTreeBase.DirectoryTreeBase(database=None)

Bases: object

__init__(database=None)

changeDirectoryGroup(paths, recursive=False)

Bulk setting of the directory group

Parameters:

paths (dictionary) – dictionary < lfn : group >

changeDirectoryMode(paths, recursive=False)

Bulk setting of the directory mode

Parameters:

paths (dictionary) – dictionary < lfn : mode >

changeDirectoryOwner(paths, recursive=False)

Bulk setting of the directory owner

Parameters:

paths (dictionary) – dictionary < lfn : owner >

countSubdirectories(dirId, includeParent=True)

createDirectory(dirs, credDict)

Checking for existence of directories

exists(lfns)

existsDir(path)

Check the existence of the directory path

findDir(path, connection=False)

Find directory ID for the given path

findDirs(paths, connection=False)

Find DirIDs for the given path list

getChildren(path, connection=False)

getDirectoryCounters(connection=False)

Get the total number of directories

getDirectoryDump(lfns)

Get the dump of the directories in lfns

getDirectoryParameters(path)

Get the given directory parameters

getDirectoryPath(dirID)

Get permissions for the given user/group to manipulate the given directory

getDirectoryReplicas(lfns, allStatus=False)

Get replicas for files in the given directories

getDirectorySize(lfns, longOutput=False, rawFileTables=False, recursiveSum=True)

Get the total size of the requested directories. If longOutput flag is True, get also physical size per Storage Element

Parameters:

• longOutput (bool) – if True, also fetches the physical size per SE

• rawFileTables (bool) – if True, uses the File table instead of the pre-computed values

• recursiveSum (bool) – if True (default), takes into account subdirectories

getFileIDsInDirectoryWithLimits(dirID, credDict, startItem=1, maxItems=25)

Get file IDs for the given directory

getFileLFNsInDirectory(dirID, credDict)

Get file lfns for the given directory or directory list

getFileLFNsInDirectoryByDirectory(dirIDList, credDict)

Get file LFNs and IDs for the given directory or directory list

Parameters:

• dirIDList (list) – List of directory IDs

• credDict (dict) – dictionary of user credentials

Returns:

S_OK/S_ERROR with Value dictionary {“DirLFNDict”: dirLfnDict, “IDLFNDict”: idLfnDict} where dirLfnDict has the structure <directory_name>:<list of contained file names>, idLfnDict has structure <fileID>:<LFN>

getPathPermissions(lfns, credDict)
