ResourceStatusHandler¶
ResourceStatusHandler
Module that allows users to access the ResourceStatusDB remotely.
- class DIRAC.ResourceStatusSystem.Service.ResourceStatusHandler.ResourceStatusHandler(*args, **kwargs)¶
Bases:
RequestHandler
The ResourceStatusHandler exposes the DB front-end functions through a XML-RPC server, functionalities inherited from
DIRAC.Core.DISET.RequestHandler.RequestHandler
According to the ResourceStatusDB philosophy, only functions of the type: - insert - update - select - delete
are exposed. If you need anything more complicated, either look for it on the
ResourceStatusClient
, or code it yourself. This way the DB and the Service are kept clean and tidied.To can use this service on this way, but you MUST NOT DO IT. Use it through the
ResourceStatusClient
. If offers in the worst case as good performance as theResourceStatusHandler
, if not better.>>> from DIRAC.Core.DISET.RPCClient import RPCCLient >>> server = RPCCLient( "ResourceStatus/ResourceStatus" )
- __init__(*args, **kwargs)¶
Constructor
- Parameters
handlerInitDict (dictionary) – Information vars for the service
trid (object) – Transport to use
- auth_ping = ['all']¶
- auth_refreshConfiguration = ['CSAdministrator']¶
- auth_whoami = ['all']¶
- export_addIfNotThere(table, params)¶
This method is a bridge to access
ResourceStatusDB
remotely. It does not add neither processing nor validation. If you need to know more about this method, you must keep reading on the database documentation.- Parameters
- table - string or dict
should contain the table from which querying if it’s a dict the query comes from a client prior to v6r18
- params - dict
arguments for the mysql query. Currently it is being used only for column selection. For example: meta = { ‘columns’ : [ ‘Name’ ] } will return only the ‘Name’ column.
- Returns
S_OK() || S_ERROR()
