CLHEP: Reflects the release of the official CLHEP 1.5

CLHEP v1.5, cvs rtag V01-05-00

New Features in release:
Matches the official CLHEP 1.5.
StdHepC++ package:
The StdHepC++ package is now in CLHEP (editor Lynn Garren) StdHepC++ is a "validated" (as opposed to "as is") component of CLHEP, fully recommended for use as part of ZOOM, just like CLHEP Random.
Random package:
Bug fix
Minor bug fixes in Random involving SaveEngineStatus for non-stateless distributions (e.g RandGauss)
Faster (and stateless) distributions:
RandGaussQ and RandGaussT derived from RandGauss
RandPoissonQ and RandPoissonT derived from RandPoisson
RandLandau
RandBit
NonRandomEngine
RandMultiGauss moved to "correct" place in Tools
Mods to JamesRandom for improved persistency prospects
HepStats
A HepStats class to factor out utility functions needed in common by various distributions, e.g. erfQ, flatToGaussian, gammln.
Standards
Improved adherence to the CLHEP conventions such as use of StdHep:: namespace, and correction of practices leading to warnings on various compilers
Vector package:
Fix of a technique in RotateUz that was leading to poor numerical accuracy
Other packages:
The Hist module, which had been obsolete, is disabled
Other packages considered "as is" for ZOOM users have minor improvements.
Platforms checked:
KAI on IRIX
KAI on RedHat 5.0 (cdfpca) with CDF environment
Various platforms at CERN, including DEC, SUN...
Dependencies:
None
Coming soon:
This first release of StdHepC++ does not take full advantage of C++ in terms of object-oriented design. A future release will rectify this.
Backward incompatibilities:
HepAList is deprecated and will go away in a future CLHEP release. The HepAList sort function is disabled at this time.

SpecialFunctions: GNU Scientific Library -- Initial release

SpecialFunctions v1.0, cvs rtag V01-00-00

New Features in release:
The Special Functions areas of the GSL library:
Airy functions
Bessel Functions
Claussen Integrals
Hydrogen atom wavefunctions
Dawson Integrals
Debye Integrals
DiLogarithms
Elliptic integrals (Jacobi and Legendre forms)
Error Functions
Exponential Integrals
Elementary functions (exponential, trig, hyperbolic, log...)
Fermi-Dirac integrals
Gamma fucntions, factorials, binomial coefficients...
Gegenbauer polynomials
Hypergeometric functions
Laguerre polynomials
Legendre polynomials, spherical harmonics
PolyGamma functions (derivatives of gamma functions)
Synchotron functions
Transport functions
Polar conversions, angle standardization
Wigner functions (3j, 6j, 9j, will have Klebsch-Gordan)
Zeta functions
Platforms checked:
Linux (KCC)
Irix (KCC)
Library builds under gcc (IRIX) but has not yet been tested there.
Dependencies:
• Execptions v 1.3 or higher
• ZMutility v 1.5.5 or higher
Warnings:
The package is intended to provide only these special functions and, as such, is a subset of the entire GNU Scientific Library.
No other parts of the GNU Scientific Library are included with this package. Those other parts are in no way tested or validated by ZOOM, nor do we promise that they will build. In fact, certain parts are known to have gcc-specific syntaxes, and are known NOT to compile on IRIX under KCC, which relies on the native C compiler.
Coming soon:
Documentation is via the GSL reference and a short "translation guide." More convenient tables and a main package page are being developed.

ErrorLogger: Collective logging features

ErrorLogger v1.3.1, cvs rtag V01-03-01

New Features in release:
ELcollected destinations
The ELcollected destination (and associated ELrecv method) are now released in beta form, and have been tested. Framework writers are encouraged to try this mechanism out and if probelms arise, to feed back further requirements.
Graded assertions
Graded assert macros that route information to the ErrorLog rather than to cerr. Both the usual abort- if-not-met assertions, and warn-if-not-met assertions are provided.
Abnornal exits
In cases where the framework enables aborting based on severity of an error message, the abort() routine is called instead of exit(). This provides better debugging information, including a core file.
Platforms checked:
KAI on with CDF environment
KAI on with D0 environment
Linux on cdfpca with CDF environment
Dependencies:
ZMutility v1.2.3 or higher
ISOcxx v1.1 or higher
Coming soon:
The whole matter of using global statics for severity levels will be revamped, making things less fragile overall.

ZMtools: Two new tools: Graded Asserts and HolderPtr.

ZMtools v1.4, cvs rtag V01-04-00

New Features in release:
New tool -- assertN
Graded assert macros, that can be turned off with finer granularity than ordinary assert().
New tool -- HolderPtr
Pointer which, when copied, also makes a copy of the pointed-to object.
Platforms checked:
ZMtimer
• KAI on d02ka with D0 environment
• KAI on cdfsga with CDF environment
• KAI on cdfpca with CDF environment
Augmented Exceptions
• KAI 3.4 and 3.3 on IRIX 6.5 and 5

Block New Features in release:
Ntuples
Fixed potential memory management problem that was not painful since most users rarely delete Ntuples during a job.
Root 2.24.04a
Support for Root 02_24_04a (but does not require this version).
Root branches
ROOT filemanger can elegantly support branches with TObject (was actually present in HepTuple 1.5).
Platforms checked:
KAI on d02ka with D0 environment
KAI on cdfsga with CDF environment
KAI on RedHat 5.0 (cdfpca) with CDF environment
NT with Microsoft C++ 5.0 with D0 environment
egcs 1.1.1 on fnpat1
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_22_06 or higher for ROOT
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 vsIntel/Dec). This inconvenience will NOT be present with the Histoscope manager.
• It is currently impractical to do static instantiation of nTuple and histogram objects.
Coming soon:
Histogram arrays web documentation
ntuple for the Root filemanager documentation.

LinearAlgebra

LinearAlgebra v1.2.17, cvs rtag V01-02-17

New Features in release:
Improved algorithm for better speed in inversion of 5x5 and 6x6 matrices.
Platforms checked:
KAI 3.3e
KAI on d02ka (earlier)
KAI on cdfsga (earlier)
KAI on linux
Restrictions:
ZOOM exceptions
The ZOOM exceptions mechanism will be utilized in a future release. These will allow the user to catch this sort of errors, handle them and contiunue, skip the event, or whatever; and if the error is not handled the usual C++ exception will be issued. This is not yet in place.
Math functions (like cos, sin) have not been implemented.
Namespace is not yet in this package.
Dependencies:
ZMutility v1.2.3 (or higher)
ISOcxx v1.1 or higher
Coming soon:
Small symmetric matrix models, and possible small correlation matrix models (which assume positive definiteness).

ISOcxx

ISOcxx v1.1.5, cvs rtag V01-10-05

New Features in release:
Hooks for gcc 2.95-2
ISOcxx does work with gcc; however gcc is presently missing 4 crucial headers which would need to be supplied before it can routinely be used.
New defects detected and dealt with:
DEFECT_NESTED_CLASS_ID
member-using defect
Add test and cure for pascal(!) keyword
Add test for at() presence (no cure as yet)

Fixed <strstream> problems
Remove need for internal symlinks.
Fix algorithm checking for <limits>, <locale>, and <string> headers.
New option
Add ISOcxx_ALLOW_DRAFT_HEADERS option to cope with outside packages.

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 on IRIX 6 cdfsga
KAI on (linux) cdfpca
KAI on SunOS 5 fcdfsun1
NT with Microsoft C++ 6.0
Integration with SRT2, which is necessary for smooth and transparent use of ISOcxx, is progressing on NT.
GCC on IRIX6 (modulo lack of library headers)
GCC on Linux (modulo lack of library headers)

Dependencies:
None.

Restrictions:
NT not yet practical for client use; this awaits completion of the incorporation of D0's SRT2 for NT into the actual SRT2.
Non-SRT usage mode not yet available.

Coming soon:
Supply adequate libraries for gcc 2.95.2
Checkout on SGI native compiler
Checkout on native compilers for other Unix platforms with SRT2 available.
