* [svn-r2611] Purpose:Quincey Koziol2000-09-287-254/+700
| | | | | | | | | | | | | Rearrange code Description: The data sieve buffering code for contiguously stored datasets was wedged in the H5F_arr_read/H5F_arr_write routines. Solution: Created a new H5Fcontig.c to hold I/O routines for contiguously stored datasets (like H5Fistore.c for chunked dataset I/O routines) and moved data sieving code into those routines. Platforms tested: Solaris 2.6 (i.e. baldric)
* [svn-r2610] Purpose:Quincey Koziol2000-09-281-28/+325
| | | | | | | | | | | | | | | | | | Code Optimization. Description: The optimized routines for copying regular hyperslabs in memory have been using the same matrix routines to copy their hyperslab pieces as the routines for irregularly shaped hyperslabs. This ends up imposing lots of extra overhead on the optimized routine, since it basically "knows" all the matrix information it needs. Solution: Keep track of the [small] amount of matrix information necessary to perform the regular hyperslab copies in the optimized routines themselves instead of using the matrix routines. This improves the performance for the benchmark I'm running from ~18 seconds to ~12 seconds and should apply to parallel I/O situations also. Platforms tested: Solaris 2.6 (i.e. baldric)
* [svn-r2606] Purpose:Quincey Koziol2000-09-271-32/+243
| | | | | | | | | | | | | | | Code Optimization Description: The matrix operations are currently the hot-spot in the library code for regular hyperslab operations. Solution: Unrolled loops for 3 of the more heavily used functions (H5V_stride_optimize2, H5V_hyper_stride & H5V_hyper_copy) for the common cases (i.e. up to 3-D datasets). This squeezes some more blood out of the stone (turnip? :-) and improves the h5hypers.c benchmark on baldric by another 20-25%. Platforms tested: Solaris 2.6 (i.e. baldric)

* [svn-r2601] Purpose:Quincey Koziol2000-09-272-5/+3
| | | | | | | | | | | | Bug Fix Description: The core and log VFL drivers were leaking small amounts of memory when they were used. Solution: Free the appropriate memory block (for the core driver) and don't allocate a block (for the log driver). Platforms tested: Solaris 2.6 (i.e. baldric)
* [svn-r2600] Purpose:Quincey Koziol2000-09-2615-27/+580
| | | | | | | | | | | Implemented new feature Description: Added data sieve buffering code to raw I/O data path. This is enabled for all the VFL drivers except the mpio & core drivers. Also added two new API functions to control the sieve buffer size: H5Pset_sieve_buf_size() and H5Pget_sieve_buf_size(). Platforms tested: Solaris 2.6 (i.e. baldric)
* [svn-r2599] Purpose:Quincey Koziol2000-09-261-0/+4
| | | | | | | | Document new feature Description: Mention data sieve buffering for next release. Platforms tested: Solaris 2.6 (i.e. baldric)
* [svn-r2597] Purpose:Quincey Koziol2000-09-261-2/+2
| | | | | | | | | | | Fix compiler warning Description: "HUGE_VAL" (a double value) was being put into a float type and generating a warning during compile time. Solution: Replaced "HUGE_VAL" with "FLT_MAX" Platforms tested: FreeBSD 4.1
* [svn-r2595] Purpose:Albert Cheng2000-09-262-0/+43
| | | | | | | | | | Feature Description: Added a new document of all the controls (compiler macros, environment variables, ...) that affect the functionality of the libraries and tools. Platforms tested: Viewed with MS IE.
* [svn-r2594] Purpose:Quincey Koziol2000-09-261-24/+18
| | | | | | | | | | | | Small Code Cleanup Description: Code to optimize adjacent (i.e. contiguous) hyperslab was ugly and used too many temporary variables. Solution: Computed the optimized hyperslabs slightly differently and got rid of unnecessary temporary variables. Platforms tested: FreeBSD 4.1
* [svn-r2591] Purpose:Bill Wendling2000-09-252-592/+602
| | | | | | | | | | | | Libtool bug Description: The AR macro wasn't being propagated to the libtool file correctly. When libtool was being generated, it wasn't recoginizing the AR that was set in the configure script. Solution: export the AR macro after it's set. Platforms tested: Linux
* [svn-r2590] Purpose:Albert Cheng2000-09-241-96/+111
| | | | | | | | | | | | | | | | | | | Bug fix Description: The old code was using count as the block size. The result was asking for a slab of count blocks, each of 1 element. The recent change in the hyperslab algorithm exposed this problem. (The old algorithm merge the count blocks back into 1 big block of count elements.) (This error was due to that the block argument was not in the very early version of hyperslab. Then it was not updated since it had been "working".) Solution: Added in the block argument to the setup and calculation of slab and its data. Also found a dumb error in the dataset_fill algorithm in which stride was used in the calculation. Not so for the cases of BYROW and BYCOL. Platforms tested: modi4 parallel, both -64 an -n32 modes.

* [svn-r2587] Purpose:Quincey Koziol2000-09-223-4/+69
| | | | | | | | | | | | | | | | | | | Bug fix (sorta) Description: When the stride and block size of a hyperslab selection are equal, the blocks that are selected are contiguous in the dataset. Prior to my hyperslab optimizations, this situation used to be detected and somewhat optimized to improve performance. I've added more code to optimize for this situation and integrated it with the new hyperslab optimization that weren't very efficient for that case as they should have been. Solution: Detect contiguous hyperslab selections (i.e. block size in a dimension is the same as the stride in that dimension) and store the optimized, contiguous version of that hyperslab. We also store the original, un- optimized version of the hyperslab to give back to the user if they query the hyperslab selection they just made. Platforms tested: FreeBSD 4.1
* [svn-r2586] Purpose:Bill Wendling2000-09-221-1/+1
| | | | | | | | | | | | | Bug Fix Description: The prototype for the H5Pregister function has a variable named `class'. This is a reserved word in C++ and causes the C++ compiler to freak. Solution: This variable's name was changed to cls_id in the .c file, so I changed it in the header file to cls_id to match. Platforms tested: Linux

* [svn-r2583] Purpose:Quincey Koziol2000-09-201-0/+13
| | | | | | | | | | | | | Bug Fix. Description: An assertion in the local heap code was mistakenly checking against too large of a value for the size of new local heap created. When used with larger-sized (>10KB) variable-length objects, it was failing the check. Solution: Corrected to check against the actual size of the heap allocated, without the heap header. Platforms tested: FreeBSD 4.1

* [svn-r2572] Purpose:Albert Cheng2000-09-191-4/+10
| | | | | | | | | | | | | | | | | | Feature Description: Most tests are done inside a for-loop. Whenever a test exits with error, the for-loop does a "exit 1" to exit the make. "make -i" could not catch and ignore the error status. Solution: Replaced "exit 1" with break. At the end of the for-loop, test if all tests have been run. If not, the for-loop is ended by the break command, thus raise an error. Now, 'make -i' can catch and ignor it. Also added the test of variable HDF5_Make_Ignore inside the for-loop to indicate the desire to ignore errors when the HDF5_Make_Ignore is set to a non-null/blank string. Platforms: Tested on modi4 and eirene.

* [svn-r2563] Purpose:Thomas Radke2000-09-151-0/+10
| | | | | | | | | | | | | | | | | Added the Stream Virtual File Driver to the list of drivers used for trying to open a file via h5dump_fopen(). Description: The Stream VFD was added at bottom of the driver list for h5dump_fopen(). If no driver succeeded to open a file given by its filename the Stream VFD would try to do so by parsing the filename as an 'hostname:port' argument, open a socket to that address and read read the file. This feature can be used to h5ls/h5dump streamed files. Platforms: All platforms (also between heterogenous).
* [svn-r2562] Purpose:Thomas Radke2000-09-151-0/+379
| | | | | | | | | | | | | | | | | | | | | | | | | | | Added test program to verify the Stream Virtual File Driver. Description: This program tests the functionality of the Stream Virtual File Driver. 1. It spawns two new processes, a sender and a receiver. 2. The sender opens an HDF5 file for writing and writes a sample dataset to it. On closing the file the Stream VFD would send the file contents to any connected client. 3. The receiver serves as a client attempting to open an HDF5 file for reading. On opening the file the Stream VFD would establish a socket connection to the sender process, identified by its hostname (which is localhost in this example) and a port number, and read the file contents via this socket. Aftwerwards the dataset is read from the file into memory and verified. 4. The main program waits for termination of its two child processes and returns their exit code. Platforms: Tested so far under Linux, Irix 32/64bit, OSF1, Solaris, Cray Unicos, Hitachi SR8000, IBM AIX. Not tested under Windows yet.
* [svn-r2561] Purpose:Thomas Radke2000-09-151-2/+5
| | | | | | | Add the Stream VFD test program to the 'make check' targets. Description: Added stream_test to the TEST_PROGS variable and a rule to build it.
* [svn-r2560] Purpose:Thomas Radke2000-09-151-0/+1
| | | | | | | Include the Stream VFD's header file H5FDstream.h. Description: All the VFD's header files are included by hdf5.h itself for convenience.
* [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-r2556] Purpose:Thomas Radke2000-09-151-0/+1
| | | | | | | | | | | Added the H5FD_stream_fapl_t type to the TypeString mapping table. Description: This servers for proper substitution of the H5TRACE macros in the Stream VFD sources. Platforms: All platforms.
* [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-r2554] Purpose:Thomas Radke2000-09-151-0/+1
| | | | | | | | | | Add the socket library to make's LIBS variable. Description: The socket library is needed to build HDF5 with the Stream VFD. Platforms: Solaris
* [svn-r2553] Purpose:Thomas Radke2000-09-151-0/+18
| | | | | | | | | | | | Added new option --with-Stream-VFD. Description: The configure option --with-Stream-VFD[={yes}|{no}] is used to configure HDF5 to build the Stream Virtual File Driver. The default is not to build it. Platforms: all platforms
