* [svn-r4904] Purpose:Quincey Koziol2002-02-061-16/+49
| | | | | | | | | | | | | | | | | | Bug fix Description: Generic property classes derived from an existing class were not having the parent class's properties copied into the new class. Additionally, derived classes were not being detected correctly. Solution: Copied properties from parent class into derived class. Modified H5P_isa_class_real() to walk back up the chain of parent classes to proper detect derived classes. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r4903] Purpose:Quincey Koziol2002-02-061-166/+120
| | | | | | | | Code cleanup Description: Clean up H5D_read and H5D_write routines, adding comments, etc. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r4891] Purpose:Quincey Koziol2002-01-312-176/+184
| | | | | | | | | | | | | | | Code speedup Description: Chunking I/O routines are reading in an entire chunk when performing I/O on the chunk, even if the chunk will be too large to cache. Solution: If the chunk is too large to cache, uncompressed and has been allocated space in the file, or if we are using the MPI-I/O VFD, perform the I/O directly to the chunk, instead of reading the chunk into memory, updating it and immediately writing the entire chunk back out. Platforms tested: FreeBSD 4.5 (sleipnir) (using serial access) and IRIX64 6.5 (modi4) (using parallel access with MPI-I/O)
* [svn-r4868] Purpose:Quincey Koziol2002-01-271-2/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fixes Description: This checkin addresses two separate bugs: #1 - When a compound datatype with a VL datatype as a field is used to read or write data, the datatype conversion paths added to the table of paths were treating the VL datatypes somewhat too genericly - they weren't dicriminating between VL datatypes used in different files and therefore there was the possibility that a path in the table having information for one file could get used with a second file, causing errors or core dumps (if the first file was closed before the later file used the path). #2 - When composite (compound, array or VL) datatype paths in the datatype conversion table are being tested to see if they can be used for the current datatypes being converted, they can cause additional conversion paths to be registered in the conversion path table. Since this causes the global table to change size and entries to move around, it is possible that the local variables tracking a potential path could become incorrect as the global table was changed out from underneath them. Both bugs fixed are described in bug #703 Solution: Two separate fixes: #1 - Changed H5T_cmp to differentiate between VL datatypes in different files and not to return datatypes in two different files as equal. #2 - Note size of global table before evaluating datatype paths. Then, after the appropriate path has been chosen, check if the size of the global table has changed and recompute the position of the path chosen in the table if necessary. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r4867] Purpose:Quincey Koziol2002-01-271-4/+11
| | | | | | | | Code cleanup Description: Added some more assertions to help debug in the future... Platforms tested: FreeBSD 4.5 (sleipnir)

* [svn-r4863] ./hdf5-devel/src/H5Tpkg.hRobb Matzke2002-01-251-0/+5
| | | | | | | | | | | | More optimizing for byte order conversion. Mostly just making code easier to follow by simplifying Duff's device coding of the loops. I also split the conversion function into two functions with different names so output from H5T debugging indicates whether the optimized or unoptimized case was invoked. 2002-01-25 10:48:34 Robb Matzke <matzke@arborea.spizella.com> *: Added prototype for H5T_conv_order_opt().
* [svn-r4862] ./hdf5-devel/src/H5Tconv.cRobb Matzke2002-01-251-537/+401

Unrolled two loops by hand resulting in <300 lines of code which is a few percent faster and far easier to read.

H5T debugging will report the conversion function as either "ibo(opt)" or "fbo(opt)".
* [svn-r4851] Purpose:Quincey Koziol2002-01-232-70/+137
| | | | | | | | | | | | | | | | | | Bug Fix Description: When file space was returned to the file space free-list for reuse, occasionally raw data allocations which used space from the free-list would overlap with the metadata accumulator and get over-written with the cached information in the accumulator, corrupting the data. Solution: Check if the space about to be recycled on the free-list is going to be used for raw data and also overlaps with the metadata accumulator cache, avoiding using space that fits those criteria. This fixes bug #701 Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r4842] Purpose:Quincey Koziol2002-01-172-72/+53
| | | | | | | | | | | | Feature improvement Description: Re-write how the free-list headers were used, to reduce the amount of space added to each malloc request. Reduced header for array and block free list items from 24 bytes to 8 bytes and eliminated the header for fixed-size free list items entirely. This should reduce the amount of memory that the library uses. Platforms tested: FreeBSD 4.5 (sleipnir) & IRIX64 6.5 (modi4)
* [svn-r4841] Purpose:Quincey Koziol2002-01-171-0/+5
| | | | | | | | | | Code improvement Description: Take advantage of the "MALLOC_WORKS" flag to not force malloced memory pieces to be at least 1 byte when the malloc implementation allows malloc(0) to work. Platforms tested: FreeBSD 4.5 (sleipnir) & Cray SV1 (killeen)
* [svn-r4840] Purpose:Quincey Koziol2002-01-161-0/+3
| | | | | | | | | | New feature check Description: Added check to determine if malloc(0) returns a valid pointer for a particular architecture. Platforms tested: FreeBSD 4.5 (sleipnir) where malloc(0) works Cray SV1 (killeen) where malloc(0) doesn't work
* [svn-r4839] Purpose:Quincey Koziol2002-01-161-7/+0
| | | | | | | | | | Bug fix Description: Missed CVS conflict in ifdef'd code Solution: Editted to remove CVS conflicted code. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r4813] Purpose:Quincey Koziol2002-01-111-8/+18
| | | | | | | | | | | Bug fix Description: HDfprintf was not handling Microsoft's "%I64d" extension to printf for printing thier '__int64' type. Solution: Added code to properly detect and use this extension. Platforms tested: None! (Kent will be testing shortly)

* [svn-r4796] Purpose:Quincey Koziol2002-01-081-0/+6
| | | | | | | | | | | | | Bug fix Description: The value of H5_SIZEOF_SSIZE_T is not being updated to reflect the correct size of the ssize_t typedef, if we have to define it ourselves. Solution: Undef H5_SIZEOF_SSIZE_T at beginning of block where we define the typedef for ssize_t and then re-define it to the correct size when we've chosen a size. Platforms tested: FreeBSD 4.5 (sleipnir)

* [svn-r4772] Purpose:Quincey Koziol2002-01-042-4/+16
| | | | | | | | | | | | | | | | | | | | | | | | Bug Fix. Description: Equation to compute size of attribute in memory was incorrectly using the disk's datatype (and dataspace, but that turns out not to have been the actual issue) and when a variable length datatype was used for the attribute, the wrong size is being computed. Also, the variable-length datatype conversions aren't handling the default dataset transfer property list (H5P_DEFAULT) correctly. Solution: Changed attribute code to compute the attribute size in memory correctly by using the memory datatype & dataspace. Changed the variable-length datatype conversion code to use the default dataset transfer property list when H5P_DEFAULT is passed as the property list ID. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r4768] Purpose:Quincey Koziol2002-01-031-26/+11
| | | | | | | | | | Bug Fix/Code Cleanup Description: Duplicated call to H5T_path_find was being made. Solution: Removed one... :-) Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r4763] Bill Wendling2002-01-021-21/+6
| | | | | | | | | | | | Purpose: Feature Add Description: Needed to add the DEV_T_IS_SCALAR macro to acconfig.h so that autoheader will propagate that to the H5config.h file. Solution: Added, reran autoheader Platforms tested: Linux
* [svn-r4757] Purpose:Albert Cheng2001-12-306-1069/+75
| | | | | | | | | | | | | | | | | | Removing the DPSS (gridstorage) driver source code. Description: The DPSS (using Grid-Storage) driver is retired. Removed the configure option with-gridstorage from configure.in. Cvs remove the following files ./src/H5FDdpss.c ./src/H5FDdpss.h ./test/dpss_read.c ./test/dpss_write.c Regenerated Dependencies files (some had to be hand-edited since 'make depend' did not cover them.) Removed reference to DPSS Virtual file driver from H5F.c. Platforms tested: modi4 (Parallel; -with-gass=...), eirene, arabica (fortran, cxx).
* [svn-r4756] Purpose:Quincey Koziol2001-12-222-1/+8
| | | | | | | | Code Cleanup Description: Updated function tracing information Platforms tested: Linux 2.2.x (eirene)
* [svn-r4747] Purpose:Quincey Koziol2001-12-202-4/+163
| | | | | | | | | | | | | | Bug Fix. Description: The H5Rget_object_type function could not get the object type for dataset region references. Solution: Added a new function, H5Rget_obj_type, to replace H5Rget_object_type. The new function requires the reference type as an additional parameter, in order to allow queries on different reference types to be performed correctly. Platforms tested: FreeBSD 4.4. (sleipnir)
* [svn-r4736] Purpose:Quincey Koziol2001-12-181-0/+4
| | | | | | | | | | | Bug Fix Description: H5Tinsert was allowing compound datatype fields to be inserted past the end of the datatype. Solution: Added range check in H5T_insert Platforms Tested: FreeBSD 4.4 (sleipnir)
* [svn-r4732] Bill Wendling2001-12-181-3/+3
| | | | | | | | | | | | | | | Purpose: Bug Fix Description: Committing the changes in the MPI/IO stuff so that parallel HDF5 will work on HP-UX. It seems that on HP-UX, the MPI_Status variable needs to be initialized to 0 for it to work (i.e., in some other MPI calls, if there's garbage in the MPI_Status variable, then it will barf). Solution: Initialized to 0. Platforms tested: HP-UX parallel, Linux.
* [svn-r4714] Purpose:Albert Cheng2001-12-131-1/+2
| | | | | | | | Bug fix Description: Fixed a previous commit that introduced an undeclared variable error. Platforms tested: eirene (serial, pp), modi4(pp)
* [svn-r4706] Purpose:Quincey Koziol2001-12-1214-276/+265
| | | | | | | | | | | | Code cleanup Description: Tweaked internal error handling macros to reduce the size of the library's object code by about 10-20%. Also cleaned up some compiler warnings... Platforms tested: FreeBSD 4.4 (sleipnir)
* [svn-r4696] Raymond Lu2001-12-1124-92/+631
| | | | | | | | | | | | | | | | | Purpose: Modify H5Fclose behavior Description: The HDF5 actual file close behaves in several ways in terms of if there are still objects(dataset, group, datatype) opened in file. Solution: Added a new file access property, file close degree. It has four values, H5F_CLOSE_DEFAULT H5F_CLOSE_WEAK H5F_CLOSE_SEMI H5F_CLOSE_STRONG The way a file is closed is decided by these values. Platforms tested: IRIX64 6.5, SunOS 5.6, FreeBSD 4.4
* [svn-r4695] Purpose:Quincey Koziol2001-12-111-40/+0
| | | | | | | | | | | | | | | | | | Bug Fix Description: The file metadata macros generate unaligned access warnings on the IA64 architecture. Solution: Got rid of bogus big-endian vs. little-endian differentiation when encoding and decoding file metadata and use proper set of macros to prevent unaligned access problems. This fixes bug #672. Platforms tested: FreeBSD 4.4 (sleipnir)
* [svn-r4693] Purpose:Quincey Koziol2001-12-111-2/+2
| | | | | | | | | | | | | | | | | | | | Bug Fix Description: The code in H5Sselect_hyperslab_valid contained an fencepost error and is allowing selections which overlap the extent by exactly one element in any dimension to pass as valid instead of flagging the selection as invalid. This bug only affects hyperslabs which have been OR'ed together, not the selection from a single H5Sselect_hyperslab. This fixes bug #550. Solution: Changed an '>' to an '>=' and added new regression test to check for error. Platforms tested: FreeBSD 4.4 (sleipnir)
* [svn-r4680] Purpose:Quincey Koziol2001-12-064-6/+12
| | | | | | | | | | | | | Code cleanup Description: Property that H5P(g|s)et_hyper_cache uses is no longer in use inside the library. Solution: Removed H5P(g|s)et_hyper_cache API functions, except when backward compatibility is turned on. When backward compatibility is turned on, the property is defined by the library, but unused internally. Platforms tested: FreeBSD 4.4 (sleipnir)

* [svn-r4676] Purpose:Quincey Koziol2001-12-052-0/+121
| | | | | | | | | | | | | | | | Backward Compatibility Fix Description: One of H5P[gs]et_buffer's parameters changed between v1.4 and the development branch. Solution: Added v1.4 compat stuff around H5P[gs]et_buffer implementation and testing to allow v1.4.x users to continue to use their source code without modification. These changes are for everything except the FORTRAN wrappers - I spoke with Elena and she will make the FORTRAN wrapper changes. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4675] Purpose:Quincey Koziol2001-12-052-2/+115
| | | | | | | | | | | | | | | | | | Backward Compatibility Fix Description: One of H5P[gs]et_sieve_buf_size's parameters changed between v1.4 and the development branch. Solution: Added v1.4 compat stuff around H5P[gs]et_sieve_buf_size implementation and testing to allow v1.4.x users to continue to use their source code without modification. There are no C++ or FORTRAN wrappers for these functions. There are also no regression tests for these functions... :-( Platforms tested: FreeBSD 4.4 (hawkwind)

| | | | | | | | | | | | | | | | | | Backward Compatibility Fix Description: One of H5P[gs]et_meta_block_size's parameters changed between v1.4 and the development branch. Solution: Added v1.4 compat stuff around H5P[gs]et_meta_block_size implementation and testing to allow v1.4.x users to continue to use their source code without modification. There are no C++ or FORTRAN wrappers for these functions. There are also no tests for these API functions currently... :-( Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4673] Purpose:Quincey Koziol2001-12-052-0/+52
| | | | | | | | | | | | | | Backward Compatibility Fix Description: H5Pset_fapl_log's parameters have changed from a simple "verbosity" level to bit-masked flags to enable various behaviors. Solution: Added in v1.4 compat stuff, on the unlikely chance that others are actually using this code in some production way. There are no C++ or FORTRAN wrappers for this call. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4670] Purpose:Quincey Koziol2001-12-052-0/+131
| | | | | | | | | | | | | | | | Backward Compatibility Fix Description: One of H5P[gs]et_sym_k's parameters changed between v1.4 and the development branch.

| | | | | | | | | | | Bug fix Description: Missing a statement for an else branch when HAVE_GETTIMEOFDAY was defined, which caused most machines to fail compiling. Solution: Re-arranged if/else statement to eliminate problem. Platforms tested: FreeBSD 4.4 (sleipnir)
* [svn-r4665] Purpose:Quincey Koziol2001-12-032-113/+190
| | | | | | | | | Code cleanup Description: Changed the logging file driver to use bitmasked flags for features to enable, instead of using a verbosity level. Platforms tested: Solaris 2.6 (baldric)
* [svn-r4664] Purpose:Quincey Koziol2001-12-032-70/+68
| | | | | | | | Code cleanup Description: Check in some small speedups for chunked storage I/O. Platforms tested: Solaris 2.6 (baldric)
* [svn-r4657] MuQun Yang2001-11-281-8/+8
| | | | | | | | | | | | | Purpose: a minor bug on H5T.c Description: should be HEREUTRN_ERROR(...,...,int,...) instead of HERUTRN_ERROR(...,...,int*,...) Solution: change HERETURN_ERROR(...,...,NULL,...) into HERETURN_ERROR(...,...,FAIL,...) Platforms tested: windows 2000
* [svn-r4656] Purpose:Quincey Koziol2001-11-272-4/+8
| | | | | | | | | Bug fix Description: Moved some executable code out of an assert() and check the results of the code with an assert(). Platforms tested: Solaris 2.6 (baldric)
* [svn-r4650] Purpose:Quincey Koziol2001-11-271-1/+1
| | | | | | | | Bug fix Description: Fix another typo from today's big "overflow" commit. Platforms tested: Solaris 2.6 (baldric)
* [svn-r4647] Purpose:Quincey Koziol2001-11-271-1/+1
| | | | | | | | | Bug fix Description: Changed return value from "FAIL" to "NULL" for error condition, which was caused the SGI machines testing the GASS drivers to fail over the weekend. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r4646] Purpose:Quincey Koziol2001-11-271-1/+1
| | | | | | | | Bug fix Description: Fix typo which caused thread-safe tests to fail over the weekend. Platforms tested: IRIX64 6.5 (modi4) with thread-safe code enabled.
* [svn-r4645] Purpose:Quincey Koziol2001-11-271-0/+2
| | | | | | | | | | Bug Fix Description: Replace an 'if' statement taken out in commit earlier today which was necessary for routing around endian conversions when zero elements were converted. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r4644] Purpose:Quincey Koziol2001-11-271-5/+2
| | | | | | | | Code cleanup Description: Fix small warning on SGI compilers Platforms tested: IRIX64 6.5 (modi4)
* [svn-r4643] Purpose:Quincey Koziol2001-11-2727-789/+844
| | | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Windows is generating hundreds of warnings from some of the practices in the library. Mostly, they are because size_t is 32-bit and hsize_t is 64-bit on Windows and we were carelessly casting the larger values down to the smaller ones without checking for overflow. Also, some other small code cleanups,etc. Solution: Re-worked some algorithms to eliminate the casts and also added more overflow checking for assignments and function parameters which needed casts. Kent did most of the work, I just went over his changes and fit them into the the library code a bit better. Platforms tested: FreeBSD 4.4 (hawkwind)
