From 349ca8daa9a1d0f094d716ea603d7d41ac14b862 Mon Sep 17 00:00:00 2001 From: James Laird Date: Fri, 18 Mar 2005 12:19:36 -0500 Subject: [svn-r10234] Purpose: Added Packet Table to high-level APIs Description: The Packet Table is an API that allows the user to append records ("packets") to a table, and read the back again. It supports fixed-length records with a defined datatype and variable-length records. It also supports a "current record" index to track the user's position in the table. Solution: The Packet Table code lives in hl/src, and its tests in hl/test. Some code is shared between the H5TB table and the H5PT Packet Table in the form of functions in H5HL_private.c. Some documentation exists for a previous version of the API. Updated documentation and C++ wrapper API coming soon. Platforms tested: sleipnir, eirene, copper, modi4 --- MANIFEST | 5 + hl/Makefile.am | 10 +- hl/Makefile.in | 2 +- hl/src/H5HL_private.c | 167 ++++++++++ hl/src/H5HL_private.h | 55 +++ hl/src/H5PT.c | 862 +++++++++++++++++++++++++++++++++++++++++++++++ hl/src/H5PT.h | 125 +++++++ hl/src/H5TB.c | 43 +-- hl/src/Makefile.am | 5 +- hl/src/Makefile.in | 10 +- hl/test/Makefile.am | 2 +- hl/test/Makefile.in | 20 +- hl/test/test_packet.c | 907 ++++++++++++++++++++++++++++++++++++++++++++++++++ 13 files changed, 2158 insertions(+), 55 deletions(-) create mode 100644 hl/src/H5HL_private.c create mode 100644 hl/src/H5HL_private.h create mode 100644 hl/src/H5PT.c create mode 100644 hl/src/H5PT.h create mode 100644 hl/test/test_packet.c diff --git a/MANIFEST b/MANIFEST index 659f8fb..f442e86 100644 --- a/MANIFEST +++ b/MANIFEST @@ -1584,11 +1584,16 @@ ./hl/src/H5TB.h ./hl/src/H5DS.c ./hl/src/H5DS.h +./hl/src/H5PT.c +./hl/src/H5PT.h +./hl/src/H5HL_private.c +./hl/src/H5HL_private.h ./hl/test/Makefile.am ./hl/test/Makefile.in ./hl/test/test_image.c ./hl/test/test_lite.c ./hl/test/test_table.c +./hl/test/test_packet.c ./hl/test/test_ds.c ./hl/test/test_table_le.hdf5 ./hl/test/test_table_be.hdf5 diff --git a/hl/Makefile.am b/hl/Makefile.am index f178df1..780e494 100644 --- a/hl/Makefile.am +++ b/hl/Makefile.am @@ -20,12 +20,10 @@ include $(top_srcdir)/config/commence.am if BUILD_FORTRAN_CONDITIONAL FORTRAN_DIR = fortran endif +##if BUILD_CXX_CONDITIONAL +## CXX_DIR = c++ +##endif -SUBDIRS=src test $(FORTRAN_DIR) - -##lib progs tests test _test: -## @@SETX@; for d in $(SUBDIRS); do \ -## (cd $$d && $(MAKE) $@) || exit 1; \ -## done +SUBDIRS=src test $(CXX_DIR) $(FORTRAN_DIR) include $(top_srcdir)/config/conclude.am diff --git a/hl/Makefile.in b/hl/Makefile.in index d3a17ed..634e3bd 100755 --- a/hl/Makefile.in +++ b/hl/Makefile.in @@ -262,7 +262,7 @@ H5CC_PP = $(bindir)/h5pcc H5FC = $(bindir)/h5fc H5FC_PP = $(bindir)/h5pfc @BUILD_FORTRAN_CONDITIONAL_TRUE@FORTRAN_DIR = fortran -SUBDIRS = src test $(FORTRAN_DIR) +SUBDIRS = src test $(CXX_DIR) $(FORTRAN_DIR) # Automake needs to be taught how to build lib, progs, and tests targets. # These will be filled in automatically for the most part (e.g., diff --git a/hl/src/H5HL_private.c b/hl/src/H5HL_private.c new file mode 100644 index 0000000..723e9ea --- /dev/null +++ b/hl/src/H5HL_private.c @@ -0,0 +1,167 @@ +/**************************************************************************** + * NCSA HDF * + * Scientific Data Technologies * + * National Center for Supercomputing Applications * + * University of Illinois at Urbana-Champaign * + * 605 E.
