22 Function Bool_t GetHLTStatus() added to preprocessor interface. It will return
23 the status of HLT read from the run logbook.
25 Revision 1.16 2007/08/22 09:20:50 hristov
26 Updated QA classes (Yves)
28 Revision 1.14 2007/05/30 06:35:21 jgrosseo
29 Adding functionality to the Shuttle/TestShuttle:
30 o) Function to retrieve list of sources from a given system (GetFileSources with id=0)
31 o) Function to retrieve list of IDs for a given source (GetFileIDs)
32 These functions are needed for dealing with the tag files that are saved for the GRP preprocessor
33 Example code has been added to the TestProcessor in TestShuttle

38 Revision 1.12 2007/04/05 08:05:55 acolla
39 Conversion from online to offline detector name in StoreReferenceFile
41 Revision 1.11 2007/04/04 10:29:18 jgrosseo
42 1) Storing of files to the Grid is now done _after_ your preprocessors succeeded. This is transparent, which means that you can still use the same functions (Store, StoreReferenceData) to store files to the Grid. However, the Shuttle first stores them locally and transfers them after the preprocessor finished. The return code of these two functions has changed from UInt_t to Bool_t which gives you the success of the storing.
43 In case of an error with the Grid, the Shuttle will retry the storing later, the preprocessor does not need to be run again.
45 2) The meaning of the return code of the preprocessor has changed. 0 is now success and any other value means failure. This value is stored in the log and you can use it to keep details about the error condition.
47 3) New function StoreReferenceFile to _directly_ store a file (without opening it) to the reference storage.
49 4) The memory usage of the preprocessor is monitored. If it exceeds 2 GB it is terminated.
51 5) New function AliPreprocessor::ProcessDCS(). If you do not need to have DCS data in all cases, you can skip the processing by implemting this function and returning kFALSE under certain conditions. E.g. if there is a certain run type.
52 If you always need DCS data (like before), you do not need to implement it.
54 6) The run type has been added to the monitoring page
56 Revision 1.9 2007/02/28 10:42:58 acolla
57 Run type field added in SHUTTLE framework. Run type is read from "run type" logbook and retrieved by
58 AliPreprocessor::GetRunType() function.

61 reading of run parameters from the logbook
62 online offline naming conversion

68 Changes required by Effective C++
70 Revision 1.4 2006/08/08 14:20:49 jgrosseo
71 Update to shuttle classes (Alberto)
73 - Possibility to set the full object's path in the Preprocessor's and
74 Shuttle's Store functions
75 - Possibility to extend the object's run validity in the same classes
76 ("startValidity" and "validityInfinite" parameters)
77 - Implementation of the StoreReferenceData function to store reference
78 data in a dedicated CDB storage.
