Jan 22, 2001:

The following release was announced January 22, 2001:

CLHEP v1.6.1, cvs rtag V01-06-01

Merge of Vector with ZOOM PhysicsVectors package
• All existing CLHEP capabilities and syntaxes preserved.
• All capabiliites available in ZOOM PhysicsVectors now available for corresponding CLHEP/Vector classes.
• Separation into multiple .cc files to avoid dragging in excessive unused code.
• See
  • List of key merge issues
  • Formulas and Definitions document
Added new package - GenericFunctions
Function objects which represent a wide spectrum of functions and may be combined and manipulated according to the rules of function composition.
Added new package - Evaluator
Utility to go from a string expressing an expression, to the value of that expression. Thus a program can accept an expression as input and use it in its calculations.
Disabled and removed dreprecated packages:
• Alist
• String
• Combination
Code organization:
• Moved docs for Random from docs/ to Random/doc/.
Bug Fixes and warning cures:
Fixed bug in Geometry package in Plane3D::transform()
Added definition of HepSTL in CLHEP.h
Fixes and Corrected warnings in Random
• on Linux when compiled with g++ -pedantic -Wall.
• More accurate code for drand48() on NT. DRand48Engine now produces exactly the same sequences on all platforms.
• Minor fix in HepRandom::createInstance()
Dependencies:
The ZOOM version of CLHEP depends on Exceptions (v1.3 or higher)
Backward incompatibiliites:
The long-deprecated HepAList, HepString, and Combinations packages are no longer present.

PhysicsVectors v2.0, cvs rtag V02-00-00

Merge of ZOOM PhysicsVectors package with CLHEP Vector
• PhysicsVectors include files are found in the same location as before (user code need not change).
• All existing PhysicsVectors capabilities and syntaxes preserved except:
  • Direct use of non-trivial accessors as L-values, as in

     SpaceVector v; v.phi() = myAngle; 

  • Direct application of Rotations and LorentzTransformations to containers of 3- and 4-vectors
• ZOOM PhysicsVectors classes are now derived from the corresponding CLHEP classes.
  E.g., SpaceVector is now derived from HepThreeVector
• See
  • List of key merge issues
  • Formulas and Definitions document
Dependencies:
• Exceptions v1.3 or higher
• ZMutility v1.6 or higher
• ISOcxx v1.3 or higher (to allow CDF code to compile with C++ exceptions disabled)
Backward incompatibiliites:
The following syntaxes, which had not appeard in any user code, are no longer supported:
• Direct use of non-trivial accessors as L-values
• Direct application of Rotations and LorentzTransformations to containers of 3- and 4-vectors
Coming Soon:
The web page has not yet been updated to reflect the CLHEP merge.

ISOcxx v1.3; cvs rtag V01-03-00

ISOcxx can now be enabled even if not all code units include ISOcxx/ISOcxx.h

New Features in release:

ISOcxx can now be enabled transparently.
• That is, an experiment can now safely place a universal USE_ISOcxx in their makes, without requiring every header to include ISOcxx.h.
• This also makes it convenient to try out new compilers without the ISOcxx corrections.
• Including ISOcxx/ISOcxx.h is nonetheless recommended.
  Some code units that depend upon ISOcxx corrections or defect definitions would still need to explicitly include ISOcxx.h.
• In some cases (mostly having to do with symbols defined on the command line) USE_ISOcxx could not be made completely transparent.

Additional defects detected and, where possible, cured:
• DEFECT_BAD_MAP_DEFAULT_ALLOCATOR
• DEFECT_BAD_LIST_SPLICE
• DEFECT_BAD_ITERATOR_ARGS
• DEFECT_BAD_BITSET_SUPPORT
• DEFECT_NO_IOS_MANIPULATORS
• DEFECT_NO_DEFAULT_TEMPLATE_PARAMETERS
• DEFECT_NO_IOS_BASE
• DEFECT_NO_AUTO_PTR
• correction of deficiencies with fmtflags manipulators boolabpha, showbase, showpos, skipws, uppercase, unitbuf and adjustfield manipulators internal, left, right and basefield manipulators dec, hex, oct and floatfield manipulators fixed, scientific
Employ _sstream header for improved compliance

See general package documentation at http://www.fnal.gov/docs/working-groups/fpcltf/Pkg/ISOcxx/doc/0ISOcxx.html
as well as the html Defect Summary List and Defects Database.
Platforms checked:
Note: For this product, a platform is "checked" when the build - which discovers defects and prepares files that aid client code by transparently coping with those defects - has succeeded, and a test sample client code successfully excercised the defect correction.
If the package has been checked out for one instance of a system/compiler/switches combination, then installation on a similar platform should be trivial.
• KAI 3.3 under IRIX 6.5, SUnOS 5, Linux 5.2
• KAI 3.4 under IRIX 6.5, SUnOS 5, Linux 6.1
• KAI 4.0b under Linux 6.1
• KAI 4.0c under IRIX 6.5
• KAI 4.0c under IRIX 6.5 with exceptions disabled
• gcc 2.95-2 under IRIX 6.5, SUnOS 5, Linux 6.1
Dependencies:
None
Restrictions:
Non-SRT usage mode not yet available.

HepTuple v1.7 cvs rtag V01-07-00

New Features in release:
Make HepTuple work using release 2.26 of ROOT as the file manager.
Repair syntax error in HepHBookFileManager that was caught by KAI 4.0.
Fix problem with tagname containing an index name.

Dependencies:
ZMutility v1.3.7 or higher
Exceptions v1.2.1 or higher
ISOcxx v1.1 or higher
Optional:
• Cernlib library must be linked in for HBOOK
• histo v5_0_3a0 or higher for histoscope
• root v2_26_00 or higher for ROOT
  HepTuple 1.7 will not work with ROOT 2.25 or earlier
Restrictions:
There is a bug in HBOOK with regard to columns of doubles in N-tuples:
These are NOT portable among platforms with different endian-ness (SGI vs Intel/Dec). This inconvenience will NOT be present with the Histoscope manager.
It is currently impractical to do static instantiation of nTuple and histogram objects.
HBOOK Columwise Ntuples are restricted to 50 variables.
HBOOK columnwise Ntuples are restricted to no more than 50 named variables per block. Each array -- either fixed length or variable length -- counts as a single named variable. In addition, the total number of items, counting each array element as a separate item, is limited to 50,000 for floats and 5,000 for doubles.
A good workaround is to have multiple blocks; each may have up to this many variables.
Coming soon:
• Histogram arrays web documentation.
• Ntuple for the Root filemanager documentation.
