Constructor & Destructor Documentation

◆ KVRemoteDataSetManager()

KVRemoteDataSetManager::KVRemoteDataSetManager ( )

Default constructor.

virtual

Destructor.

Definition at line 35 of file KVRemoteDataSetManager.cpp.

Member Function Documentation

◆ CheckAvailability()

void KVRemoteDataSetManager::CheckAvailability ( )

virtual

Check availability of datasets in repository associated to this data set manager For remote data sets/repositories, this is done by transferring from the remote machine the file $KVROOT/KVFiles/[repository name].available.datasets and reading from it the datasets and subdirectories which are present on the remote machine. Example file: INDRA_camp1 : root INDRA_camp2 : INDRA_camp4 : INDRA_camp5 : raw,recon,ident,root INDRA_e416a : raw, INDRA_e475s :

Reimplemented from KVDataSetManager.

Definition at line 163 of file KVRemoteDataSetManager.cpp.

◆ OpenAvailableDatasetsFile()

Bool_t KVRemoteDataSetManager::OpenAvailableDatasetsFile ( )

privatevirtual

Transfers file $KVROOT/KVFiles/[repository name].available.datasets from remote machine containing info on available datasets and associated subdirectories in remote data repository. Copies to local working directory and opens for reading, if all goes well (returns kTRUE). Returns kFALSE in case of problems.

N.B. If 'curl' is used to transfer the file, we check for HTML code in the file It can happen that 'curl' itself does not give an error when the web server is down, but transfers a file which looks like this: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>403 Forbidden</title> </head><body>

Forbidden

You don't have permission to access /KaliVedaDoc/ccali.available.datasets on this server.

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.
