* [svn-r2559] Purpose:Thomas Radke2000-09-151-8/+8
| | | | | | | | Add the Stream VFD sources to the appropriate makefile variables. Description: Added H5FDstream.c to the LIB_SRC variable and H5FDstream.h to the PUB_HDR variable for building the Stream VFD.
* [svn-r2558] Purpose:Thomas Radke2000-09-151-0/+3
| | | | | | | | | | Define HAVE_STREAM. Description: If the Stream VFD was configured the configured script will expand this into '#define HAVE_STREAM 1' in H5config.h and '#define H5_STREAM 1' in H5pubconf.h.
* [svn-r2557] Purpose:Thomas Radke2000-09-151-0/+7
| | | | | | | Added registration of the Stream Virtual File Driver. Description: The Stream VFD is registered here if it was configured.
* [svn-r2555] Purpose:Thomas Radke2000-09-152-0/+1037
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Added source files for the Stream Virtual File Driver. Description: The Stream VFD allows users to stream complete HDF5 files via socket connections between different applications. Files which were created anew are flushed to any connected client on each H5Fflush() or H5Fclose() operation. Files which are opened as read-only will be read from a socket on a H5Fopen() call. The driver's H5FDset_fapl_stream() routine allows to pass in several parameters such as an external socket descriptor, some socket options, and flags for broadcasting a received file. If an external socket is provided the Stream VFD would use that for the socket calls. Otherwise it parses the filename argument in H5Fcreate()/H5Fopen() for a 'hostname::port' parameter. All files processed by the Stream VFD are kept in memory (same way as the core VFD does). Platforms: Tested so far under Linux, Irix 32/64bit, OSF1, Solaris, Cray Unicos, Hitachi SR8000, IBM AIX. Not tested under Windows yet.
* [svn-r2551] Purpose:Quincey Koziol2000-09-141-76/+180
| | | | | | | | | | | | | | | | Fix last couple of errors from introducing "regular" hyperslab feature into the library. Description: Code was blindly dereferencing data structures which aren't defined when operating on regular hyperslabs. Solution: Check for regular hyperslab defined and retrieve information from regular hyperslab info instead of mucking about in other hyperslab information. Platforms: Solaris 2.6

* [svn-r2544] Optimized regular hyperslab I/O routines and data structures. ↵Quincey Koziol2000-09-132-312/+1886
| | | | | | | | | | | | | On my benchmarks, they are about 4-5 times faster than before. We no longer generate "general" hyperslab data structures for regular hyperslabs, the general data structures are only generated when needed for irregular hyperslabs. Still fixing a couple of nook-and-cranny functions to understand the new information for the regular hyperslabs, so the tests aren't completely passing, but I wanted to get this checked in for Elena's benchmarks. I should have more/all tests passing later today.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fixes Description: All tests were core=dumping in IRIX64. The bug is in Generic property list creation in which malloc asked for 2*64-1 bytes due to coding bug. The object creation failed but the return code was not checked. Program eventually crashed. Solution: H5F.c: Check the return code from new file object creation and flag error accordingly. H5FL.c: H5FL_arr_free is a replacement for H5MM_xfree which accepts null value as a legal argument value. H5FL_arr_free assert on it. Since other parts of the code have been passing null value to H5MM_xfree, H5FL_arr_free must accept it too until all the calling routines are changed to not pass Null. H5P.c: some routine passes in 0 as the hashsize value which is uintn. The expression (hashsize-1) underflows to the largest unsigned int for some machines. Thus the calloc failed. Cast hashsize to unsigned int first (this assumes hashsize stays within the signed int data range. H5Smpio.c: Added the extra parameter because the H5FD_write has been redefined. Platforms tested: IRIX64 -64 and -n32

* [svn-r2504] Revised routine to add hyperslabs to the selection, sorting the ↵Quincey Koziol2000-09-041-78/+36
| | | | | | | | arrays of hyperslab boundaries after adding them all, instead of maintaining the sorted order during each addition. This boosts performance for sub-sampled (i.e. strided) hyperslabs by about a factor of 10! :-)
* [svn-r2502] Added limits to the free lists, so they will automatically ↵Quincey Koziol2000-08-311-6/+6
| | | | | | garbage collect and not eat all the memory in the machine (by default :-)
* [svn-r2501] Added several free lists for commonly used & abused data ↵Quincey Koziol2000-08-311-120/+525
| | | | | | | | | | | | | structures. Also added code to allow metadata to be allocated out of a more contiguous block ("metadata aggregation") and also code for "catching" small metadata write calls and building a buffer of the small pieces of metadata for later writing as one, larger, block ("metadata accumulation"). These features are enabled on a per VFL driver basis with the new VFL 'query' call and both currently enabled for the sec2, family and stdio drivers. The mpio VFL driver enables only the "metadata aggregation" code, not the "metadata accumulation" code. All the other drivers have these features turned off.
* [svn-r2500] Added fields to file data structures to allow metadata ↵Quincey Koziol2000-08-311-2/+34
