o) opt in ObjectProxy.h: skip creating of temporary TClassRef
o) TPython::Exec now returns kFALSE on failure
o) TPySelector now takes a python module, so that that file is
looked up through PYTHONPATH, and it searches for the
TPySelector derived class to instantiate and use

Initial TPySelector prototype for use with PROOF. The prototype
works, but needs improvement error reporting, resilience, and
optimizations. Basic Idea:
from ROOT import TPySelector
class MyPySelector( TPySelector ):
def Begin( self ):
print 'py: beginning'
def SlaveBegin( self, tree ):
print 'py: slave beginning'
def Process( self, entry ):
print 'py: processing for:', self, self.fChain
return 1
def SlaveTerminate( self ):
print 'py: slave terminating'
def Terminate( self ):
print 'py: terminating'
def GetSelector():
return MyPySelector()
The for now conventional "GetSelector()" will be removed soon, in
favor of the same scheme (a derived class check) like with C++
selectors. The code above can then be run like so (localhost):
import time
from ROOT import TDSet, TProof
dataset = TDSet( 'TTree', 'h42' )
dataset.Add( 'root:// .... ' )
proof = TProof.Open('')
time.sleep(1) # needed for GUI to settle
print dataset.Process( 'TPySelector', 'MyPySelector.py' )
Do make sure to transport the MyPySelector.py in a .par file (or
similar), and do make sure that the environment on the other end
is proper.
