From Philippe:
This enhance the support in TTreeFormula for (conceptual) array
with 2 varying dimensions in the case the 2nd dimensions has
some zero length and a fixed index is used.
This patch also add the ability to format the output of
TTree::Scan. The option parameter can now contains the following
customization:
// colsize=ss
// Where 'ss' will be used as the default size for all the column
// If this options is not specified, the default column size is 9
// precision=pp
// Where 'pp' will be used as the default 'precision' for the
// printing format.
// col=xxx
// Where 'xxx' is colon (:) delimited list of printing format for
// each column if no format is specified for a column, the default is
// used.
// For example:
// tree->Scan("a:b:c","","colsize=30 precision=3 col=::20.10");
// Will print 3 columns, the first 2 columns will be 30 characters long,
// the third columns will be 20 characters long. The printing format used
// for the columns (assuming they are numbers) will be respectively:
// %30.3g %30.3g %20.10g

From Philippe
This patch restores and enhances TTree::Scan previous behavior regarding arrays.
It nows always (unless user request otherwise) print all the requested elements
of all the arrays. The printing of multi-dimensional array is now done in a
linear, non-synchronized fashion. In particular this means that selection on
2D arrays (including array within a TClonesArray) might not print the correct
instance of the arrays (in case of using arrays of un-even dimension)
You can now limit the number of element in the array by using the string option 'lenmax=dd':

From Philippe:
The following patch implements TTree variable alias.
To use them:
mytree->SetAlias("mult","fPx*fPy");
mytree->Draw("mult");
Note that the aliases have been added to the TTree object so that they can be persistent (with the tree) if you choose.
Also note that the alias are not checked for validity until they are used in a Draw or Scan command.
Existing alias are silently replaced.
The new functions are:
TTree::SetAlias
TTree::GetAlias
TChain::GetAlias
TTree::GetListOfAliases
This patch also adds operator= for TFormula, TF1, TF2, TF3 (it calls the respective Copy member functions). It makes TTreeFormula::operator= private (Copy has not been implemented yet).
Also some of the TFormula and TTreeFormula codes (those stored in fOper) has been aliased to enums (this renders the code is little bit more readable and searchable).
TFormula and TTreeFormula have been updated to handle strings in a more flexible (and for TTreeFormula to be able to return them).
