From Andreas:
TAlienFile inherits now directly from TXNetFile. This was possible by
introducing another factory function in TAlienFile (TAlienFile::Open),
moving some private to protected members and changing some function to
virtual in the parent classes. For the new factory function of the plubing
rootrc.in had to be modified.
Using the occasion, I have also implemented that, that
TAlienFile tries automatically to open any of the existing images of a
file, starting with the 'closest' one, if it fails with the next
replica aso. This is implemented right now only for reading. It is not
ought to do loadbalancing by random shuffling of the SE order.
There are some changes in TAlienCollection for Panos, to build the 'and'
of two TAlienCollections and to read evelist from the xml file.
Some memory leaks have been fixed in TAlienResult/TGridResult etc.
Finally to have a consistent file name (e.g. a TAlienFile has it's LFN as
a filename - eventhough it inherits from TXNetFile, which does not like
LFN's), I had to introduce another argument to TXNetFile (in the end with
a default value), to tell TXNetFile, that is has to open an xrootd url,
but it has to 'carry' another name. The normal functionality is not
touched by this.

From Andreas:
here are my modifications to interface the Grid file catalog
(AliEn in this case) with TChain data sets. Some changes are just
one-liner changes to make some base class things virtual or to set
some members. With these changes one can do:
// connect
TGrid::Connect("alien://");
// query
TGridResult* result = gGrid->Query("/alice/cern.ch/user/p/peters/analysis/miniesd/","*.root","","");
or
TGridResult* result = gGrid->Query("/alice/cern.ch/user/p/peters/analysis/miniesd/","*.root","","-l 50"); // to query maximum 50 files
result->Print(""); // or result->Print("l") or result->Print("all"); => Tells you also the complete size of the TDSet (the ALICE one is 68 GB)
// build chain for ALICE files
TChain* mychain = new TChain("esdTree","AliceSession");
// Get a list of FileInfo Objects
// -> I cannot use directly a list of FileInfo objects in TGridResult,
// because TGridResult can be also a list of jobs etc ....
TList* list = result->GetFileInfoList()
// add them to a chain
mychain->AddFileInfoList(list); // adds all
mychain->AddFileInfoList(list,10); // adds only the first 10
// to use PROOF then, you need to do
mychain->Lookup(); // open's all files via TAlienFile over
the redirector and replaces the
alien URL with the physical location
of the file on the cluster
(including the access token)
mychain->SetProof();
mychain->Draw("ESD.fTrigger");

From Andreas and Derek:
modify the abstract grid interface to be smaller and more flexible.
Added abstract classes to describe Grid Jobs, JobStatus, JDL, file collections.
Removed specific PROOF interface which is not needed anymore.

From Andreas Peters:
updated TGrid and related classes, and updated TAlien plugin for the AliEN grid.
To build the TAlien plugin one needs to install the AliEn client API lib.
How the basic TGrid class works with AliEn is described in the file
README/README.ALIEN.
Also provided is a Grid/AliEn controlled distribtution and startup system
for PROOF. This uses the TGridProof/TAlienProof classes and the LFN/PFN
information in the TDSet to find the AliEn sites where the data resides.
On these sites PROOF daemons (proofd) are started by AliEn (using an
interactive submission queue). Once the proofd's are running standard
PROOF is started which then connects to these proofd's. After that the
user performs his analysis, like on a local PROOF cluster.
