Extend to TClassEdit::Init to actually initialize the list of typedef to avoid desugaring (aka TNormalizedCtxt).
Modify TClintWithCling and rootcling to call the updated initialization routine.
Implement ROOT::TMetaUtils::ReSubstTemplateArg which uses the fact that in the decl for class template instances, the types inserted/replaced where one of the template parameters used to be, is wrapped by a clang::SubstTemplateTypeParmType, to re-substitute them with the partially desugared version of the template arguments (aka the one still containing Double32_t and Float16_t).
Update TClingBaseClassInfo and TClingDataMember to record the data member types with the template argument resubstitution.
[Note:
To properly handle default template, the patch
interpreter/llvm/src/ROOT-patches/allow-typedef-in-default-tmplt-param.cpp
needs to be applied. As well as defining in TMetaUtils.cxx the macro
R__HAS_PATCH_TO_MAKE_EXPANSION_WORK_WITH_NON_CANONICAL_TYPE

Improve the time required to load libraries, in particular at process loading time.
For example the total time to completion of root.exe -b -l -q is cut in half!
We now wait until CINT is initialized before starting to execute any dictionary setup function.
In CINT's allocate function, avoid having to recalculate the 'index' of the G__var_array.
Enhance the performance of TClassEdit by introducing TSplitType which can be reused for a few a
the string based type manipulation that TClass needs to do.
In the implementation of TClassEdit::ShortType and TClassEdit::GetSplit, this patch reduces the
amount of work done (by reducing the number of calls to TClassEdit::CleanType, in
particular in the case where we know that the type is already prep-ed)

From Axel:
Add new mode 1<<7 to TClassEdit::ShortType() which removes all default
template arguments from a type name, as long as the type's dictionary
has been loaded. Also fix a doc bug in ResolveTypedef.

From Philippe:
This patches prevents a confusion due to possible aliasing of STL container of Long64_t.
This patches also transform TClassEdit from a class with only static member to a namespace.
(The same should be done for TMath).
This allow some simplication by allowing the usage of
using namespace TClassEdit;
which removes the need to always use TClassEdit:: to refer to the functions.

From Philippe:
This patch should resolve completely the issue discovered by Minos (related to
typename being typedefs). It also repairs the I/O for fixed size array of
TObject.
TString:
add constructor and operator= taking a std::string argument
TROOT:
GetClass now properly resolve templateClass<typedef>.
Previously the typedef resolution was restricted to the full name.
TClassTable:
Look for an existing TClass directly in TROOT::fListOfClasses to
avoid the potential loading behavior of TROOT::GetClass
TCint::UpdateClassInfo
Also look for possible alias name in the list of TClass objects.
In particular, depending on the load order of libraries and file,
the Emulated class for container<int> might be container<Int_t> or
vce et versa.
TClass::Init
When we have a templated class, also look for existing Emulated
class which may have a different name.
TStreamerElement/TStreamerInfo
Use the name with resolved typedef in the TStreamerElement.
Also repair the I/O for fixed size array of TObjects.
TClassEdit:
Add a utility to resolve the typedefs inside a typename.
This resolution has 2 modes. One where it resolved all
typedefs which should be used to compare 2 typename and
establish equality. A second where it resolved all
typedefs __except__ for the ROOT integral type typedefs,
this version is used to create the typename that will be
save on file. This is necessary to avoid the replacement
of (for example) Long64_t by its platform dependent version.

Original Path:
trunk/metautils/inc/TClassEdit.h
File length: 1808 byte(s)
From Philippe:
This mega patch introduces a new implementation of the STL I/O
which is backward and forward compatible. In addition this is more
exactly a new implementation or an extension of the container I/O.
We are introducing a new abstract interface:
"TVirtualContainerProxy", which can be implemented to present a
proxy to any collection which the I/O (and TTreeFormula) can use
then transparently.
The TVirtualContainerProxy interface allows to the I/O system to
request some information and to execute some essential function of
the container:
what kind of object/data does it contain
does it contain pointers
how to insert data into the container
how to retrieve an array of pointer to the elements inside
how to create a collection object
how to clear the collection
how to resize the collection
how to streamer the collection (if needed)
how to calculate the sizeof the collection
how to calculate the number of elements of the collection.
Using those primitives, the I/O and TTreeFormula should be able to
access any collection. The I/O should also be able to handle the
splitting of collections that can be split (i.e. contains a single
type of object/data).
The current compromise selected between code duplication,
performance of the I/O of TClonesArray and vector of pointers and
the performance of the I/O of other containers, was to have on
function handle all collection as if they were a C-style array of
pointers to data. This implies for example that the I/O of vector
of object current passes via the construction of temporary array
of pointer. The cost of this construction is usually ~Qjust~R the
cost of calculating the addresses of the elements and assigning it
to an array element.
Registering a collection proxy will be similar to
static int dummy = GenerateInitInstance((CollectType*)0x0)-
>AdoptCollectionProxy(new CollectTypeProxy));
Follows a few details on the modifications made to some of the
files and classes.
Bytes.h:
Work around a problem in the MSVC++ 6.0 optimizer. This should
not affect other compilers.
String:
Included the std::string dictionary into G__Base2.cxx, this
insures its presence at all time.
Added a new file string.cxx holding the streamer for
std::string.
RConfig.h
Added proper ansi stream configuration for AIX, KCC
Added template specialization defect for MSVC
TBrowser
Start adding the ability to browser non TObject classes
TBuffer
To handle the reading and writing array of objects, added:
Int_t CheckByteCount(UInt_t startpos, UInt_t bcnt, const
TClass *clss, const char* classname);
Int_t CheckByteCount(UInt_t startpos, UInt_t bcnt, const
char *classname);
void ReadFastArray(void *start , TClass *cl, Int_t n=1,
TMemberStreamer *s=0);
void ReadFastArray(void **startp, TClass *cl, Int_t n=1,
Bool_t isPreAlloc=kFALSE, TMemberStreamer *s=0);
void WriteFastArray(void *start, TClass *cl, Int_t n=1,
TMemberStreamer *s=0);
Int_t WriteFastArray(void **startp, TClass *cl, Int_t n=1,
Bool_t isPreAlloc=kFALSE, TMemberStreamer *s=0);
TROOT
Enhancement to make the access to gROOT not dependent for the
library loading order. In particular we added:
ROOT::GetROOT()
which should be used instead of gROOT.
Improve support for STL. In particular, now STL containers do
have a corresponding TClass object
TRealData
Replace SetStreamer by AdoptStreamer that allow to use not only
a streamer function but also streamer object (allowing streamer
with a state for Foreign classes)
TString:
Improve streamer performance
TSystem:
More consistency of the return value of TSystem::CompileMacro
build/unix/makecintdlls.sh
Stop making the string.dll
config:
enhance sgicc makefiles
cont:
fix TBits::operator=
TClassTable now warns for duplicate only for non stl classes
TClonesArray fix a typo
gpad:
Add a new class TInspectObject to enable inspect non TObject
classes
TRootBrowser : enable inspect non TObject classes
TFormula/TTreeFormula
To enhance performance switch from using one array fOper which
contained the operation code and its arguments to using 2 arrays
fActions and fActionParams to store respectively the operation and
its parameters.
A new function Convert is used to convert old version from the
fOper to fActions. This allows cleaner coding and offer
optimization opportunities.
TTreePlayer
Start adding support in MakeClass for STL containers.
TRint/TProofServ
Insure the loading of the string support
Event.cxx
make sure to avoid memory over-write
stress.cxx
Add new parameters
stress <nevent> <style> <subbench> <portion>
if <subbench> is 1 or higher, print the benchmark results after
each test. This allows understand
which test is affect by a performance change.
portion is a binary field to indicate which test to run. This
allows to focus on a particular test.
TVirtualCollectionProxy
Abstract interface used to access any type of containers from
the I/O system and TTreeFormula. See TVectorProxy and
TEmulatedVectorProxy for examples.
TEmulatedVectorProxy
Implementation of a std::vector proxy to be able to read a
std::vector without any libraries.
TVectorProxy
Implementation of TVirtualCollectionProxy for a std::vector for
which we have the library.
TStreamerInfo.cxx
Split in 3 files: TStreamerInfo.cxx
TStreamerInfoReadBuffer.cxx TStreamerInfoWriteBuffer.cxx
All the ReadBuffer, ReadBufferClones and the new ReadBufferSTL
(similarly for WriteBuffer) have been factorized into one
function and 2 short wrappers. The new main function expect an
array of pointer to the objects (this array is most often of size
one).
TClonesArray objects pass GetObjectRef(0) to the common
ReadBuffer
vector<bla*> v pass &(v[0])
vector<bla> needs to create an intermediary array to hold the
address
This mechanism is sometimes not optimal (vector<blah>) but
allows extremely flexibly and extension. Basically, to add
support for a new container type using the StreamerInfo mechanism
(in particular allows splitting), one 'just' need to implement a
TVirtualCollectionProxy, which, in particular, will return an
array of address to the object it contains. Even std::map can be
handled with this mechanism, since, for I/O purposes, it can be
consider as a container of pairs.
Add a few optimization, including more caching via a new array
of a new struct (fComp).
Fixed a problem (re)introduced while implementing the Foreign
class CheckSum. Doing:
class Event;
f = new TFile("Event.root");
resulted in errors.
TCint
Add proper support for TClass of STL containers. Fix a memory
leak.
Add support for load TClass via a typedef.
Fix a problem with multiple inheritance
TClass
Fixed a problem (re)introduced while implementing the Foreign
class CheckSum. Doing:
class Event;
f = new TFile("Event.root");
resulted in errors.
Add a
TClass/TGenericClassInfo/TDataMember
Add support for a new interface (TVirtualCollectionProxy)
useable for STL containers or any user defined containers.
Add support for streamer with are objects (as opposed to free
standing function or methods). This allows the user a greater
flexibility in writing a streamer.
Add a few optimizations
Add CanSplit to answer the question for a whole Class (for
example some collection can not be splitted).
TClassStreamer
New class to wrap a class wide streamer
ClassStreamerFunc_t
typedef for a class wide streamer function
TMemberStreamer
New class to wrap a specific class member streamer
MemberStreamerFunc_t
typedef for a specific class member streamer function
RootStreamer
Macro to specify a free standing streamer object or function
for a class
For example:
RootStreamer(string,std_string_streamer);
TStreamerElement:
A couple of optimization/simplification.
Add support for the new STL I/O
Extend the useful
TBranchElement:
add a connection to the proper TVirtualCollectionProxy
add support for STL containers (non-split and split mode)
TTree
Make the function TTree::GetMakeClass NON-virtual for better
efficiency
Add support for STL containers
TBasket
Left (in comment) a yet unproved improvement proposed by
Victor. The preliminary tests were inconclusive performance wise
and it had (seemingly) problem with backward and forward
compatibility.
TBranch
Performance improvements
metautils
This is a new package for C++ files shared between rootcint and
meta.
It contains TClassEdit a class to help determine some property
of a class given its class name (stl, template, etc).
utils
Introduced a new file RStl.cxx to start separating rootcint in
modules.
Modified rootcint to support the new STL I/O methods.
In particular a new class RStl is in charge of doing the
generating of code for STL containers.
