| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./MANIFEST New files ./html/extern1.gif [NEW] ./html/extern1.obj [NEW] ./html/extern2.gif [NEW] ./html/extern2.obj [NEW] ./html/Datasets.html Documented external raw data storage. ./html/Datasets.html ./html/chunk1.gif [NEW] ./html/chunk1.obj [NEW] Added a picture and better description for chunking since it seems that people are thinking chunks are fixed-size at the file level instead of at the array level. ./src/H5D.c ./src/H5Dpublic.h ./test/external.c Changed H5Dget_create_parms() to H5Dget_create_plist(). ./src/H5D.c ./src/H5Farray.c ./src/H5Fprivate.h ./src/H5Oefl.c ./src/H5Oprivate.h ./src/H5Sprivate.h ./src/H5Ssimp.c ./test/external.c ./test/istore.c External raw data file I/O for contiguous storage is now working. The library supports segments of various sizes which can be scattered throughout multiple files in any order. ./test/Makefile.in Remove more temporary files.

Besides, our test files only use them in a handful of places and it's probably useless to export them to the app. The app is always written in terms of standard numeric types or its own numeric types and probably never in terms of HDF5 numeric types. If it were, then the user would have to copy from their type to hdf5 type for almost every hdf5 API function call! Same goes for return values. I also removed SUCCEED/FAIL from the API since apps should be checking against zero anyway. if (FAIL==(space=H5Screate_simple(...))) /*wrong*/ if ((space=H5Fcreate_simple(...)<0)) /*right*/ ./src/H5.c Changed arguments of H5version() from `uintn' to `unsigned'. ./src/H5Tpublic.h ./src/H5T.c Changed return type of H5Tget_nmembers() from `intn' to `int' ./src/H5A.c ./src/H5Aprivate.h ./src/H5Apublic.h Changed `H5Asearch_func_t' to `H5A_search_func_t' and moved its definition from the public to the private header file. ./html/H5.format.html Documented changes made to the external file list (H5O_EFL) message. ./src/H5D.c ./src/H5Dprivate.h ./src/H5E.c ./src/H5Epublic.h ./src/H5O.c ./src/H5Oefl.c ./src/H5Oprivate.h ./src/H5P.c ./src/H5Ppublic.h Added partial support for external raw data files. HDF5 can now describe external raw data files by listing the file names, offsets, and size for a dataset. However, we will restrict a dataset to be stored "contiguously" when the external file list is viewed as a single address space. The current implementation is unable to read/write to external files--that will come later this week as will documentation. For now, take a look at ./test/external.c, particularly the calls to H5Pset_external(). ./test/Makefile.in ./test/external.c [NEW] ./MANIFEST Added tests for external storage. Note: the read test is supposed to fail at this point since reading external datasets is not implemented yet. There is no write test. ./src/H5S.c ./src/H5Sprivate.h ./src/H5Ssimp.c Added H5S_get_npoints_max() to return the maximum possible number of data points in a data space. Added an extra argument to H5S_get_dims() which returns the maximum dims. ./src/H5F.c ./src/H5Fprivate.h ./src/H5Fpublic.h ./src/H5M.c [DEPRICATED] ./src/H5Mpublic.h [DEPRICATED] Changed `template' to `property list' in lots of places. ./src/H5Osdspace.c Removed an extra `\n' from a print statement. ./src/H5S_public.h Changed H5S_UNLIMITED to the maximum size_t value. ./test/extend.c "Extendable" is spelled "extendible". ./src/H5Farray.c ./src/H5V.c ./src/H5Vprivate.h ./test/hyperslab.c Strides are now type ssize_t instead of int. These have nothing to do with the sample granularity arguments for hyperslabs, which are also called "strides" in the code. ./test/tstab.c Changed assumptions about default address and length sizes.

* [svn-r188] Changed hbool_t from an enum to 'int' and removed ↵Quincey Koziol1998-01-281-3/+0
| | | | | | | | | | BTRUE/BFALSE/BFAIL from code. Changed interface to the H5P..hyperslab functions to 'int' instead of 'size_t'. Cleaned up lots of warnings on IRIX 6.2 platform. Minor other tweaks to get to a mostly clean build on the SGI. It still whines about 'long long' being non-standard and some "pointless comparison of unsigned with 0" but those aren't big problems.
* [svn-r163] Changes since 19980121Robb Matzke1998-01-221-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./Makefile.in Added more dependencies to .PHONY. ./src/H5D.c The write side of the I/O pipeline is implemented now too. Things are looking good for the prototype and it's just a matter of populating the library with the data type and data space conversion functions. ./src/H5Farray.c ./src/H5Fprivate.h ./test/istore.c Changed the order of the arguments for H5F_arr_read() and H5F_arr_write(). ./src/H5P.c ./src/H5Pprivate.h Changed the names of the arguments of H5P_find(). Fleshed out the mgath and fscat callback types. ./src/H5Psimp.c Added stubs for H5P_simp_mgath() and H5P_simp_fscat() that operate on the entire data space. Quincey, once you have the data space hyperslab stuff in place let me know and I'll finish the H5P_simp_*() functions to do partial I/O. Or you can take a look at it too if you like; there's some comments in there for you. ./src/H5V.c ./src/H5Vprivate.h Changed dimensionality arguments from `size_t' to `intn' to be consistent with the rest of the library and to get rid of warnings on 64-bit Irix.

However, partial I/O hasn't been added to the I/O pipeline yet in H5D.c

* [svn-r155] Changes since 19980114Robb Matzke1998-01-161-0/+219
---------------------- ./html/Datasets.html Removed some archaic comments about data spaces. Fixed example code. ./MANIFEST ./html/H5.format.html ./src/H5O.c ./src/H5Oprivate.h ./src/H5Ocstore.c [DELETED] ./src/H5Oistore.c [DELETED] ./src/H5Olayout.c [NEW] ./src/Makefile.in ./test/istore.c Replaced H5O_CSTORE and H5O_ISTORE messages with a more general H5O_LAYOUT message. ./src/H5D.c ./src/H5Dprivate.h ./src/H5Dpublic.h A little more work on the pipeline. Access to the file data is through the new H5F_arr_read() and H5F_arr_write() which do I/O on hyperslabs of byte arrays and don't depend on data layout. This should simplify the I/O pipeline quite a bit. I also added another argument to H5Dread() and H5Dwrite() to describe the hyerslab of the file array on which I/O is occuring. We discussed this at last week's meeting. ./src/H5Farray.c [NEW] Added functions that sit on top of H5F_block_read() and H5F_istore_read() and implement a common set of functions between all layouts. This means I/O of hyperslabs of byte-arrays in the file to arrays of bytes in memory. When operating on arrays of elements (>1byte) then we just add another dimension. That is, a 10x20 array of int32 becomes a 10x20x4 array of bytes. [This is the area I'll be working on most of next week to implement partial I/O for contiguous data and to improve performance for chunked data.] ./src/H5Fistore.c ./src/H5Fprivate.h Replaced the H5F_istore_t data type with the layout message H5O_layout_t which looks almost the same. Eventually I'd like to rename `istore' to `chunked' everywhere and use `istore' for 1-d storage where the chunks are all different sizes like in the small object heap where each object is a chunk. ./src/H5V.c Changed ISTORE to LAYOUT in one place. ./test/dsets.c Fixed for extra argument to H5Dread() and H5Dwrite().
