From e40dc71400bff4f26945bc30737f75f476126519 Mon Sep 17 00:00:00 2001 From: Magnus Lundborg Date: Tue, 9 Dec 2014 13:43:16 +0100 Subject: [PATCH] TNG version 1.7.3 Corresponds to commit e862ebe8 in the TNG repository. Large parts of the TNG code have been rewritten to avoid code duplication. Some functions have been combined. Summary of additional changes (see git log for full details): Bug fixes: Fixed bug reading last frame and time of last frame. Fix MingW build Fixed bug reading non-particle data. Check that ZLib is available before using it. Fixed bug when appending to trajectory. New functions: tng_util_num_frames_with_data_of_block_id_get() Fixed compiler warnings Improved testing suite Change-Id: I97334b1d93f21646fe1625e65e5fcdf38a0450d9 --- docs/install-guide/index.rst | 2 +- src/external/tng_io/BuildTNG.cmake | 6 +- src/external/tng_io/Doxyfile.in | 6 +- src/external/tng_io/include/compression/bwlzh.h | 26 +- src/external/tng_io/include/compression/bwt.h | 12 +- src/external/tng_io/include/compression/coder.h | 8 +- src/external/tng_io/include/compression/dict.h | 2 +- src/external/tng_io/include/compression/fixpoint.h | 8 +- src/external/tng_io/include/compression/huffman.h | 12 +- src/external/tng_io/include/compression/lz77.h | 10 +- .../tng_io/include/compression/merge_sort.h | 2 +- src/external/tng_io/include/compression/mtf.h | 16 +- src/external/tng_io/include/compression/rle.h | 8 +- .../tng_io/include/compression/tng_compress.h | 76 +- src/external/tng_io/include/compression/vals16.h | 8 +- .../tng_io/include/compression/warnmalloc.h | 4 +- .../tng_io/include/compression/widemuldiv.h | 13 +- src/external/tng_io/include/tng/tng_io.h | 393 +- src/external/tng_io/include/tng/tng_io_fwd.h | 6 +- src/external/tng_io/src/compression/bwlzh.c | 26 +- src/external/tng_io/src/compression/bwt.c | 32 +- src/external/tng_io/src/compression/coder.c | 53 +- src/external/tng_io/src/compression/dict.c | 18 +- src/external/tng_io/src/compression/fixpoint.c | 8 +- src/external/tng_io/src/compression/huffman.c | 16 +- src/external/tng_io/src/compression/huffmem.c | 10 +- src/external/tng_io/src/compression/lz77.c | 12 +- src/external/tng_io/src/compression/merge_sort.c | 6 +- src/external/tng_io/src/compression/mtf.c | 40 +- src/external/tng_io/src/compression/rle.c | 12 +- src/external/tng_io/src/compression/tng_compress.c | 166 +- src/external/tng_io/src/compression/vals16.c | 8 +- src/external/tng_io/src/compression/warnmalloc.c | 4 +- src/external/tng_io/src/compression/widemuldiv.c | 49 +- src/external/tng_io/src/compression/xtc2.c | 126 +- src/external/tng_io/src/compression/xtc3.c | 92 +- src/external/tng_io/src/lib/md5.c | 1 + src/external/tng_io/src/lib/tng_io.c | 16885 +++++++++---------- src/external/tng_io/src/tests/md_openmp.c | 2 +- src/external/tng_io/src/tests/md_openmp_util.c | 2 +- src/external/tng_io/src/tests/tng_io_read_pos.c | 3 +- .../tng_io/src/tests/tng_io_read_pos_util.c | 3 +- src/external/tng_io/src/tests/tng_io_testing.c | 1088 +- src/external/tng_io/src/tests/tng_parallel_read.c | 3 +- 44 files changed, 9170 insertions(+), 10113 deletions(-) diff --git a/docs/install-guide/index.rst b/docs/install-guide/index.rst index 8c245f4245..86462019e3 100644 --- a/docs/install-guide/index.rst +++ b/docs/install-guide/index.rst @@ -289,7 +289,7 @@ Optional build components Motif/Lesstif libraries and header files.
