Changes in the head of the v5-14-00-patches branch

• configure:
  • fix location of SQL tutorial; fixes a problem for Windows build only.

• Reflex:
  • Add explicit dependency of genreflex.(bat|sh) on genreflex python files or they won't be copied on windows (due to BUILDPYTHON=no).

Changes in version v5-14-00i (October 23, 2007)

• RooFit:
  • Roofit tar did not have binary flag and hence did not work on Windows.

• Cintex:
  • Remove limitation on length of type names.
  • Register unknown scopes as 'a', not 'n'. Fixes 24227 [8].

• TreePlayer:
  • in MakeSelector() remove limit on file name length and extend branch names from 128 to 1024 (will be completely dynamic too in the future).

• MathCore:
  • Add dictionary for all the coordinates classes based on Double32_t and for LorentzVector <PtEtaPhiM4D<Double32_t> >.

• TUnixSystem:
  • Don't return after handling kSigChild in DispatchSignals().

Changes in version v5-14-00h (September 8, 2007)

• Meta
  • Increase caching of typedef information in TCint and TClass, improving the efficiency of library loading by up to a factor 5.

• TDCacheFile
  • ReadBuffers() with vector read is implemented. Dcache version 1.7.0-39 with this functionality has just been released. We've tried with ROOT version 5.14 and 5.16. It's amazing! On some applications we got up to 12 times performance increase!

• TTreeCache
  • Reject request from TTree object other than the one that created the TTreeCache object (Hence preventing a crash is 2 trees are read from the same TFile object and one of them is being cached).

• TTree
  • Set gBranch properly before cloning a TBasket, the TBasket streamer needs it on read.
  • In Fast Merging, allow the input and output trees to have a different number of branches. This allow for dropping branches when doing a fast cloning.

• CINT/Reflex/Cintex
  • Fix for enums used in functions not having any constants once passed through Cintex.

• TXMLSetup.h
  • Fix compiler warning when compiling with gcc in strict mode.

• RooFit
  • fix memory leak in RooProdPdf.cxx.

Changes in version v5-14-00g (July 9, 2007)

• CINT/Reflex/Cintex
  • Allow interpreter access to variables in namespaces with Reflex dictionary.

• TTree MakeProxy
  • Improve memory usage (Fixes issue 25697 [9])
  • Enable support for array with 3 dimensions and more (Fixes issue 26727 [10])

• TGFALFile, TRFIOFile
  • Since the GFAL and RFIO URLs can have the form: rfio:///castor?path=FILEPATH we need to use TUrl::GetFileAndOptions() to get the file name to be passed to the GFAL and RFIO API's.
  • Add support for older libshift that do not support the :/// and ?filetype=raw syntax.

• rpm and debian build systems:
  • Remove reference to deprecated package pythia.

• TDCacheFile:
  • Add support for gsidcap protocol.
  • Work around the missing 'vector read' in the DCache protocol by requesting all the needed data in a single sequential read request (aka reading too much data but reducing the number of messages). This improves performances by a factor 20 to 50 depending on network topology.

• mathcore
  • fix a bug in the calculation of eta for the LorentzVector classes
  • add some optimization in the vector classes

Changes in version v5-14-00f (May 29, 2007)

• Pyroot
  • Add a protection in the case of where a base class is Emulated (fixes issue 25369 [11]).

• Hist, IO
  • Fix memory leaks (fixes issue 25371 [12] and 25373 [13]).

• IO
  • Fix problem with CollectionProxy for non stl container (fixes issue 25397 [14]).

• CINT/Reflex
  • Fix handling of constness for genreflex generated function call wrappers.

• CINT
  • Work around a compiler bug in gcc 3.2.3 (which lead to crash in rootcint).
  • Improve re-entranceness of G__process_cmd().

• Base
  • Add protection in error handlers against TROOT not yet being initialized (fixes issue 26200 [15]).

• Tree
  • In the TBrowser, when drilling through a TTree and clicking on a member function that returns an object, we now also list the data members.
  • Properly handle the case where the return value of a member function is an STL collection.

• GFAL
  • In TGFALFile ctor fStatCached was not initialized causing random SysStat() behaviour (fixes issue 26628 [16]).

• libGlobusAuth
  • The Globus authentication plugin now links statically all Globus libs to prevent Globus libs (libssl and libcrypto) to be used by other ROOT plugins.

• ACliC
  • Ensure that when a 32-bit binary is run on a 64-bit platform ACliC compiles with the -m32 flag.

• Unuran
  • Add missing dependency that broke parallel make.

Changes in version v5-14-00e (March 29, 2007)

• Intel icc v10 support
  • Add support for the soon to be released Intel icc v10 compiler.

• make:
  • Fix broken parallel build in case configured with option --enable-explicitlink.

• Cintex:
  • Fix return by reference of integers (fixes issue 24549 [17]).
  • Fix a bad declaration of the scope of vector<LinkManager::Link*>::iterator as a namespace when declaring a typedef of LinkManager class (fixes issue 25077 [18]).

• CINT:
  • Increase G__MAXSTRUCT and G__MAXTYPEDEF to 24000. This has no visible effect on the memory used by CINT.
  • A one-dimensional array of length one was being treated as if it were a scalar. This results in ROOT seeing an incorrect data member name, which makes tree I/O offset calculations fail.

• TTree:
  • Fix memory leak which happens when the content of the basket does not compress well (aka it should be rare).

• TObjArray:
  • Make the TObjArray::operator[] methods out-of-line.

• hadd
  • Dynamically load libTreePlayer to allow support for TTrees build with an index.

Changes in version v5-14-00d (March 9, 2007)

• SMatrix
  • Fix a bug found by LHCb (W. Hulsbergen) in the += and -= operators for symmetric matrices when using expressions like A += B + C

• Cintex:
  • Fix memory leak when calculating class offsets with instance (from S. Snyder).
  • Making Cintex more robust on dictionary autoload order (fixes issue 24450 [19]).

• TStreamerInfo:
  • Add code to allow the schema evolution from a container of doubles to the same container of Double32_t and vice et versa.

• TEnv:
  • don't issue a warning in case of duplicate resources where the resource and value are exactly the same. Fixes issue 24157 [20].

• TCint:
  • In LoadLibraryMap() maintain directory order as specified in the LD_LIBRARY_PATH.

• Mac OS X:
  • Fix options for gfortran.

• FitPanel:
  • Fix segv when closing panel.

• rootcint:
  • In ShowMember(), std::string no longer need a special case. This fix enables I/O for C-style array of strings (issue 23724 [21]).

• PyRoot:
  • Only strip namespaces in current class, not in template parameters (issue 23724 [21]).
  • Fix for handling temporaries by PyROOT/CINT of classes with new/delete operators (issue 23388 [22]).
  • Fix 32 bit cutoff (Int_t used where Long_t needed) when converting unsigned long (long)s (issue 24100 [23]).
  • Restore void*& function argument converter.

• TCastorFile, TRFIOFile, rootd and Globus authentication:
  • Disabling of 'chdir($HOME)' in 'rootd' when running in Castor mode. This is because $HOME may point to a directory not available on the servers.
  • A few optimizations in the Globus authentication.
  • Fixes in TCastorFile, TRFIOFile, TAuthenticate already in the head. The possibility to change the authentication mode on the fly is relevant here.
  • A couple of bug fixes in rpdutils.cxx found by testing these changes.

Changes in version v5-14-00c (February 12, 2007)

• Makefile:
  • The gif icons were not copied to the icons directory when doing "make install".

• makestatic.sh:
  • Exclude unuran and gdml modules.

• Cintex:
  • Fix for 23428 [24].

• Tree:
  • Fix for 23567 [25].

Changes in version v5-14-00b (January 17, 2007)

• Cintex:
  • Fix for 22866 [26].

• Reflex:
  • Fix for 22952 [27].

• Fix problem with MacroPath and DynamicPath expansion in case the paths are extended via ~/.rootrc and/or ./.rootrc files. Fixes issue 22954 [28].

• TEnv:
  • avoid reading ./.rootrc twice in case the workingdirectory is ~.

• TFile::Open to xrootd on Mac OS X Intel:
  • fixed issue 22597 [29].

Changes in version v5-14-00a (January 10, 2007)

• genreflex:
  • Ordering of dictionary classes needed for a proper conversion to CINT
  • Remove warning on windows
  • For the ordering patch, remove dependency on python 2.4

• Reflex:
  • Fix bug 22339 [30], genmap not finding input file going back to a simpler implementation of error reporting. Only dl* function errors need to reported for this class.

• ROOTClassEnhancer.cxx:
  • A problem has been detected by Ioannis running the POOL regression tests with the latest ROOT production release. The problem shows up in a rather complex model (CMS inspired I think) involving a vector of pairs containing objects embedding pool::Refs in split mode. The wrong offset is calculated for the pool::Ref producing a core dump when doing a dynamic_cast.

• THistPainter.cxx:
  • This bug is connected with fixing bug 22317 [31] which I submitted previously. Unfortunately, I got it only after release 5.14 was published. Due to the fix in THistPainter::PaintBarH the PaintAxis call was moved to the very end of the routine. But, actually, it should come before the X and Y axis pointers being permuted back. As I checked, now it looks like X axis attributes have effect on the Y axis and vice versa.

• v6_opr.cxx:
  • Move in opr.c G__bstore() function, test to long double before that of double.

• TTreeCache.cxx:
  • Avoid division by zero in entry number estimation.

• TChainIndex.cxx:
  • In TChainIndex::DeleteIndices prevent a double delete. This fixes issue 22722 [32].

• Pythonize.cxx:
  • Backport of fix for 22599 [33].

• TGFSContainer.cxx:
  • Month was off by one.
