| | | | | | | | | | | | Code cleanup Description: Tweak HSIZET_MAX macro and add HSSIZE_MAX and HSSIZET_MIN macros. Platforms tested: FreeBSD 4.8 (sleipnir) w/C++ FreeBSD 4.8 (sleipnir) w/parallel h5committested
* [svn-r6952] Purpose:Quincey Koziol2003-06-044-102/+145
| | | | | | | | | | | | | Code cleanup Description: Move testing routines into their own module, to avoid linking them into user's applications needlessly. Platforms tested: FreeBSD 4.8 (sleipnir) w/C++ FreeBSD 4.8 (sleipnir) w/parallel h5committested
* [svn-r6951] Purpose:Quincey Koziol2003-06-043-7/+11
| | | | | | | | | | | | Code cleanup Description: Clean up various warnings & comment out unused code. Platforms tested: FreeBSD 4.8 (sleipnir) w/C++ FreeBSD 4.8 (sleipnir) w/parallel h5committested
* [svn-r6950] Purpose:Quincey Koziol2003-06-042-90/+340
| | | | | | | | | | | | | | | | | | | | | | API tweak. Description: The H5Sget_select_bounds() API call was using hsize_t arrays for retrieving the 'start' and 'end' coordinates, which is counter to the rest of the dataspace API. Solution: Change the arrays to be hssize_t instead. Platforms tested: FreeBSD 4.8 (sleipnir) w/C++ FreeBSD 4.8 (sleipnir) w/parallel h5committested Misc. update: Updated all docs for this change. Added 1.4 compatibility #ifdef's
* [svn-r6942] Purpose:Quincey Koziol2003-05-317-174/+1234
| | | | | | | | | | | | | | | | | Performance improment Description: Speed up chunked dataset I/O. This breaks down into several areas: - Compute chunk selections in the file by using hyperslab operations instead of iterating over each element in the selection. - If the file and memory selections are the same shape, use the file chunk selections to compute the memory chunk selections. This required several additional dataspace, dataspace selection and hyperslab routines. Platforms tested: h5committestted (although Fortran tests failed for some reason)
* [svn-r6936] Purpose:Quincey Koziol2003-05-311-3/+3
| | | | | | | | | | | | | | | Bug fix Description: When free lists where disabled, the macros for array free list operations could possibly expand in ways that allowed incorrect numbers of objects to be operated on. Solution: Put parentheses around macro arguments when performing operations with them. Platforms tested: h5committestted (although Fortran tests failed for some reason)
* [svn-r6920] Purpose:Quincey Koziol2003-05-281-3/+3
| | | | | | | | | | | | | | | | Bug fix Description: (void *)~((size_t)NULL) on the Cray is a different value than (foo *)~((size_t)NULL) and causes some of the hyperslab algorithms to fail. Solution: Change all the 'void *' forms to 'foo *' forms. Platforms tested: Cray SV1 h5committest not needed.
* [svn-r6909] Purpose:Quincey Koziol2003-05-211-10/+14
| | | | | | | | | | | | Bug fix Description: Correct typo which didn't show up during my previous testing in production mode. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest not necessary.

| | | | | | | | | | | | Purpose: Maintenance for the second round of testing Description: Used bin/h5vers to change version number to 1.5.55 Solution: Platforms tested: arabica Misc. update:
* [svn-r6900] Purpose:Quincey Koziol2003-05-191-9/+13
| | | | | | | | | | | | | | | | | | | Bug fix Description: Fix three (!) bugs in szip filter: - we were using bytes per pixel instead of bits per pixel - we were using the size of the slowest changing dimension instead of the fastest changing dimension to compute the blocks per scanline parameter - we swapped two parameters when setting up szip_options block. Solution: Addressed bugs above. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest not needed
* [svn-r6898] Purpose:Quincey Koziol2003-05-191-1/+3
| | | | | | | | | | | Code cleanup Description: Improve error reporting for pixels per scanline check. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest not needed.
* [svn-r6891] Purpose:Quincey Koziol2003-05-171-299/+639
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix Description: Raw data I/O on chunked datasets would attempt to allocate data structures proportional to the number of chunks in the dataset on disk, instead of just the number of chunks that the I/O operation would interact with, causing operations on datasets with large #'s of chunks to fail (or become very slow), even though the actual I/O operation was very modest. Solution: This is the "scalability fix" for chunked datasets that I've mentioned we need to do, althought it's not the complete fix for the issue. Read on for the details... Only create data structures for the chunks that the I/O operation will actually act on, reducing the amount of information allocated in memory, normally. I say "normally", because this algorithm has the same problems as the original algorithm (worse actually, since the data structure for each chunk is larger now) if _all_ the chunks in a dataset with a lot of chunks are actually involved in the I/O operation. If that is the case, this code will fail in a similar way. To truly fix the problem, we would need to only create data structures for a particular number of chunks, perform the I/O on just those chunks, then release the data structures for those chunks and create data structures for the next set of chunks to access, etc. However, I think this case is pretty rare right now and we should worry about it after the 1.6.0 release. Platforms tested: h5committested
* [svn-r6890] Purpose:Quincey Koziol2003-05-172-0/+49
| | | | | | | | | | | New feature Description: Added "fast comparison" code for hsize_t's, since they are used in th raw data chunking I/O code now. Platforms tested: h5committested
* [svn-r6889] Purpose:Quincey Koziol2003-05-171-1/+1
| | | | | | | | | | Code cleanup Description: Clean up comment Platforms tested: h5committested
* [svn-r6884] Purpose: bug fixRaymond Lu2003-05-161-22/+46
| | | | | | | | Description: H5Tget_native_type didn't handle special platform like Cray properly. Solution: modify algorithm and test Platforms tested: h5committest
* [svn-r6882] Purpose:Bill Wendling2003-05-152-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix Description: The H5HG module had a couple of lines like the following: HDmemcpy(foo + 1, foo, size); This would overwrite the first character of "foo" for the total of "size" bytes. The H5Pfapl.c is an update of the trace information. Solution: Use HDmemmove instead. (Suggested by George Lewandowski at Boeing. Thanks! :-) Platforms tested: Modi4 (Fortran & Parallel) Verbena (Fortran & C++) Arabica (Fortran) Misc. update:
* [svn-r6878] Purpose:Quincey Koziol2003-05-1533-452/+574
| | | | | | | | | | | Code cleanup Description: Limit the scope on more function prototypes/macros/typedefs. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest not necessary.
* [svn-r6875] Purpose:Quincey Koziol2003-05-152-23/+29

* [svn-r6869] Purpose:Quincey Koziol2003-05-131-1/+23
| | | | | | | | | | | | | | | | | Bug fix. Description: When the same dataset is opened more than once and those references to the object are left dangling, the library would not correctly shut down the dataset API, potentially allowing the file to be truncated. Solution: "force" the dataset IDs to be released when the dataset API is being shut down by the library. Platforms tested: FreeBSD 4.8 (sleipnir) h5committested
* [svn-r6868] Purpose:Quincey Koziol2003-05-131-3/+7
| | | | | | | | | | | | | | | | | | | Bug fix. Description: If the buffer holding the list of interfaces that are attempting to be closed down becomes full, the library stops recording that an infinite loop has occurred when shutting down the interfaces. Solution: Always return the correct "pending" information. Also added ellipsis to the string of interfaces to try to make it more obvious that the buffer became full. Platforms tested: FreeBSD 4.8 (sleipnir) h5committested
* [svn-r6864] Purpose:Quincey Koziol2003-05-131-0/+1
| | | | | | | | | | | | Bug fix Description: Added missing line for file close degree setting for this VFD. Platforms tested: FreeBSD 4.8 (sleipnir) h5committested (Unfortunately, none of these tests actually exercised this driver... :-(
* [svn-r6861] Purpose:Quincey Koziol2003-05-131-1/+1
| | | | | | | | | | | | | | | | Bug fix Description: Iterating over the attributes of an object without any attributes was returning FAIL instead of 0 as the RM states. Solution: Changed return value of H5Aiterate for objects without attributes to be 0 and added regression tests for this. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest not needed.
* [svn-r6860] Purpose:Quincey Koziol2003-05-131-8/+20
| | | | | | | | | | | | | Small code cleanup Description: Remove redundant sanity check. Added a note about a potential bug. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest not necessary.
* [svn-r6857] Purpose: bug fixRaymond Lu2003-05-131-2/+18
| | | | | | | | | Description: when a datatype element size is bigger than I/O datatype conversion buffer(1MB), library reports failure. Solution: adjust conversion buffer to be at least equal to one element size Platforms tested: h5committest
* [svn-r6855] Purpose:Bill Wendling2003-05-131-0/+2
| | | | | | | | | | | | | | | | Bug Fix Description: The newly added H5TEST_DLL{VAR} macros weren't defined if it wasn't a Windows environment. Solution: "#define" them to "" and "extern" if not a WIN32 environment. Platforms tested: Linux (small change not needing full testing) Misc. update:
* [svn-r6851] Purpose:MuQun Yang2003-05-131-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | To add macro HDF5TESTDLL for windows libtest library. Description: Many HDF5 tests will use h5test.c. So we create a libtest library to 1) make tests more organized and 2) make tests more consistent with other platforms 3) reduce compiling times 4) reduce dumplicated warnings possibily generated by h5test.c However, we didn't create the corresponding libtest DLL correctly, now, some warnings are generated because of this; so for this release, we follow exactly DLL-DLL rules, to create an internal libtest DLL for our test suites. The application who used HDF5DLL will not have extra burdens to add HDF5TESTDLL and this will reflect in the release.txt Solution: USE DLL import and export library by defining macro HDF5TESTDLL and HDF5TESTUSEDLL Platforms tested: Windows 2000(the macro will not affect on non-WIN32 platforms). Misc. update:
* [svn-r6843] Purpose:Quincey Koziol2003-05-0919-51/+71
| | | | | | | | | | | | Code cleanup Description: Clean up warnings exposed by compiling on O2K. Also, revert some of Bill and my changes to the H5S_mpi_opt_types_g, etc. and settle them back into their original location. Platforms tested: h5committested.
* [svn-r6841] Purpose:Bill Wendling2003-05-081-0/+5
| | | | | | | | | | | | | | | | Bug Fix Description: A variable wasn't declared in this file. Solution: Put the extern declaration of the variable in this file. It's defined in the H5S.c module. Platforms tested: Modi4 (This affects only parallel platforms) Misc. update:

| | | | | | | | | Description: H5Sselect_hyperslab and H5Sselect_elements didn't check scalar dataspaces. Solution: put error detection in those functions. Platforms tested: eirene(simple change).
* [svn-r6837] Purpose:Quincey Koziol2003-05-0824-277/+261
| | | | | | | | | | | | | | | Code cleanup. Description: Move many package or internal function prototypes and macro definitions into tighter scope according to their current use. Added more comments where appropriate. Eliminate ancient, unused functions. Added a couple "accessor" functions to get parts of data structures which were moved out of scope. Platforms tested: h5committested

| | | | | | | | | | | | | | | Bug fix Description: New external file double-vectorized I/O routines were checking an assertion on the wrong variable (essentially a typo :-). Solution: Check correct variable. Platforms tested: FreeBSD 4.8 (sleipnir) Triple check not needed.
* [svn-r6830] Purpose:Quincey Koziol2003-05-081-1/+1
| | | | | | | | | | | | | | | | Bug fix Description: Dataspace selections created for individual chunks during chunk dataset I/O were leaking memory. Solution: Properly set reference count on selection, so they get free'd when the dataspace is closed. Platforms tested: FreeBSD 4.8 (sleipnir) Triple check not needed.
* [svn-r6829] Purpose:Quincey Koziol2003-05-082-9/+1
| | | | | | | | | | | Code cleanup. Description: Cleaned up an unusued variable and some commented out code. Platforms tested: FreeBSD 4.8 (sleipnir) Triple check not needed.

| | | | | | | | | Description: H5T_XXX_init_interface calls H5T_init_interface causing datatype not closed after file is closed. Solution: changed H5T_init_interface to H5T_init Platforms tested: h5committest
* [svn-r6825] Purpose:Quincey Koziol2003-05-0733-6352/+6666
| | | | | | | | | | | | | | | | | | | | | | | | | New feature/enhancement Description: Chunked datasets are handled poorly in several circumstances involving certain selections and chunks that are too large for the chunk cache and/or chunks with filters, causing the chunk to be read from disk multiple times. Solution: Rearrange raw data I/O infrastructure to handle chunked datasets in a much more friendly way by creating a selection in memory and on disk for each chunk in a chunked dataset and performing all of the I/O on that chunk at one time. There are still some scalability (the current code attempts to create a selection for all the chunks in the dataset, instead of just the chunks that are accessed, requiring portions of the istore.c and fillval.c tests to be commented out) and performance issues, but checking this in will allow the changes to be tested by a much wider audience while I address the remaining issues. Platforms tested: h5committested, FreeBSD 4.8 (sleipnir) serial & parallel, Linux 2.4 (eirene)
* [svn-r6823] Purpose:Bill Wendling2003-05-074-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Code Improvements/Bug Fixes Description: Comparison of equality of a double/float variable to 0.0 is not guaranteed to work and is bad practice. In H5Fcontig.c, a warning was given by a statement like: x = (++x) % y; This could be confusing to a compiler I suppose. In H5RS.c, a typedef of a structure was being tagged by the compiler as "useless" because it had the form: typedef struct foo { int var1; /* ... */ }; /* <--- note no name for this typedef */ The statement "typedef struct foo foo" is already in the header file. Solution: Test that the absolute value of the variable is < a very small positive number. Changed "x = (++x) % y" to "++x; x %= y;" instead. Removed the "typedef" from the structure in the H5RS.c file. Platforms tested: Modi4 (Parallel & Fortran) Verbena (C++ & Fortran) Arabica (Fortran) Misc. update:
* [svn-r6810] Purpose:Bill Wendling2003-05-061-2/+2
| | | | | | | | | | | | | | Update Description: Some of the TRACE macros were updated to reflect a new parameter. Platforms tested: Linux Solaris w/ zlib Irix w/ zlib Misc. update:
* [svn-r6807] Purpose:Bill Wendling2003-05-061-7/+6
| | | | | | | | | | | | | | | Change Description: Instead of using the "USE_GPFS" macro, use the "H5_HAVE_GPFS" macro which is defined during configuration and then use the new parameter to the H5P{get,set}_fapl_mpiposix functions to control if GPFS is enabled or not. Platforms tested: Modi4 (only affects the parallel stuff, so no need for full testing). Misc. update:
* [svn-r6803] Purpose:Quincey Koziol2003-05-061-7/+4
| | | | | | | | | | | Code cleanup. Description: Cleaned up a few debugging printfs. Platforms tested: FreeBSD 4.8 (sleipnir) Triple check not needed.
* [svn-r6797] Purpose:Bill Wendling2003-05-051-3/+3
| | | | | | | | | | | | | | | Feature Description: Added new flag to the H5pubconf.h file --- NO_SHARED_WRITING (H5_NO_SHARED_WRITING). It's only defined for CodeWarrior and should never be defined for other platforms unless the "open()" bug that CW has shows up on other platforms. Platforms tested: Verbena. Configure only, so no need for full tests. Misc. update:
* [svn-r6795] Purpose:Bill Wendling2003-05-052-27/+54
| | | | | | | | | | | | | | | | Feature Add Description: Added knob so that the programmer can enable or disable GPFS hints during runtime instead of having it only enabled at configure/compile time. Some of the public APIs were changed to add an extra parameter for this option... Platforms tested: Blue (LLNL). It only affects the MPI/POSIX driver, so no need to test it on non-GPFS platforms. Misc. update:
* [svn-r6793] Snapshot version 1.5 release 52HDF Admin2003-05-031-2/+2
