[svn-r925] Changes since 19981116 ---------------------- ./INSTALL.parallel [NEW] We're beginning to unify some of the parallel installation steps. This file will contain general information for installing the parallel library. It's not complete yet. ./configure.in ./configure [REGENERATED] ./src/H5config.h.in [REGENERATED] Check for xdr_int() in libnsl required on Solaris when linking with hdf4. It's found on the Irix system I tested which complains that `-lnsl' didn't resolve any symbols. Oh well. Fixed the order of searching for libdf and libmfhdf for hdf4 linking. ./configure.in ./configure [REGENERATED] ./src/H5config.h.in [REGENERATED] ./src/H5Z.c Check for compress() in libz in order to find older versions of the library that will still work for hdf4. Added a separate check for compress2() that hdf5 will use. ./configure.in ./configure [REGENERATED] ./src/H5config.h.in [REGENERATED] ./src/H5.c ./src/H5private.h ./src/H5A.c ./src/H5B.c ./src/H5Bprivate.h ./src/H5D.c ./src/H5F.c ./src/H5Farray.c ./src/H5Fcore.c ./src/H5Ffamily.c ./src/H5Fistore.c ./src/H5Flow.c ./src/H5Fmpio.c ./src/H5Fprivate.h ./src/H5Fsec2.c ./src/H5Fsplit.c ./src/H5Fstdio.c ./src/H5Gent.c ./src/H5Gnode.c ./src/H5Gpkg.h ./src/H5Gprivate.h ./src/H5HG.c ./src/H5HL.c ./src/H5O.c ./src/H5Oattr.c ./src/H5Ocomp.c ./src/H5Ocont.c ./src/H5Odtype.c ./src/H5Oefl.c ./src/H5Ofill.c ./src/H5Olayout.c ./src/H5Omtime.c ./src/H5Oname.c ./src/H5Oprivate.h ./src/H5Osdspace.c ./src/H5Oshared.c ./src/H5Ostab.c ./src/H5R.c ./src/H5RA.c ./src/H5Sall.c ./src/H5Shyper.c ./src/H5Snone.c ./src/H5Spoint.c ./src/H5Sprivate.h ./src/H5Sselect.c ./src/H5T.c ./src/H5Tbit.c ./src/H5Tconv.c ./src/H5Tpkg.h ./src/H5V.c ./test/bittests.c ./test/gheap.c ./test/hyperslab.c ./test/istore.c ./test/tmeta.c ./test/trefer.c ./test/tselect.c ./tools/h5debug.c ./tools/h5tols.c Added checks for Posix.1g types like `int8_t'. If not defined then H5private.h defines them. Changed all `int8' etc. to `int8_t'. ./src/H5A.c ./src/H5D.c ./src/H5F.c ./src/H5G.c ./src/H5I.c ./src/H5P.c ./src/H5R.c ./src/H5RA.c ./src/H5S.c ./src/H5T.c ./src/H5TB.c ./src/H5Z.c Calling H5*_term_interface() resets interface_initialize_g to FALSE so a subsequent call to H5open() (implied or explicit) reinitializes global variables properly. ./src/H5private.h ./src/H5Oefl.c ./src/H5S.c Changed MAX_SIZET, MAX_SSIZET, MAX_HSIZET, and MAX_HSSIZET to SIZET_MAX, SSIZET_MAX, HSIZET_MAX, and HSSIZE_MAX to they match the Posix.1 constants in <limits.h>. ./src/H5T.c ./src/H5Tconv.c ./src/H5Tpkg.h ./src/H5Tprivate.h ./src/H5detect.c Added 36 more integer hardware conversion functions to the type conversion table for conversions to/from `long long' and `unsigned long long'. The `long long' names will be changed shortly to make them portable to Win32. Changed H5T_init() to H5T_native_open() and added an H5T_native_close() to open and close the predefined native data types. Increased the initial size of the type conversion table from 64 to 128 entries. Reordered the 90 new integer conversion functions so the names that are printed favor `int' over `short' or `long' when two of them are the same. ./test/dtypes.c Added hardware and software integer conversion tests for the 56 functions I added recently but not the additional 36 checked in this time. That will come next. Call H5close() after each test so type conversion statistics are easier to follow. Try this: $ HDF5_DEBUG=t ./dtypes Added more debugging output for when things go wrong. ./src/H5private.h Removed trailing carriage-returns inserted by broken operating system ;-)

[svn-r925] Changes since 19981116 ---------------------- ./INSTALL.parallel [NEW] We're beginning to unify some of the parallel installation steps. This file will contain general information for installing the parallel library. It's not complete yet. ./configure.in ./configure [REGENERATED] ./src/H5config.h.in [REGENERATED] Check for xdr_int() in libnsl required on Solaris when linking with hdf4. It's found on the Irix system I tested which complains that `-lnsl' didn't resolve any symbols. Oh well. Fixed the order of searching for libdf and libmfhdf for hdf4 linking. ./configure.in ./configure [REGENERATED] ./src/H5config.h.in [REGENERATED] ./src/H5Z.c Check for compress() in libz in order to find older versions of the library that will still work for hdf4.

The `long long' names will be changed shortly to make them portable to Win32. Changed H5T_init() to H5T_native_open() and added an H5T_native_close() to open and close the predefined native data types. Increased the initial size of the type conversion table from 64 to 128 entries. Reordered the 90 new integer conversion functions so the names that are printed favor `int' over `short' or `long' when two of them are the same. ./test/dtypes.c Added hardware and software integer conversion tests for the 56 functions I added recently but not the additional 36 checked in this time. That will come next. Call H5close() after each test so type conversion statistics are easier to follow. Try this: $ HDF5_DEBUG=t ./dtypes Added more debugging output for when things go wrong. ./src/H5private.h Removed trailing carriage-returns inserted by broken operating system ;-)
