* [svn-r7952] Purpose:Quincey Koziol2003-12-131-2/+2
| | | | Bug snapshot version after creating tar file for user to test bugfix.
* [svn-r7951] Purpose:Quincey Koziol2003-12-131-1/+9
| | | | | | | | | | | | | | | | Bug fix Description: Attributes which were created with scalar dataspaces were reporting their dataspace as a simple dataspace when queried later. Solution: Fix the dataspace handling code when reading in the attribute message from the file to set the extent type correctly. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7945] Purpose:Quincey Koziol2003-12-131-2/+2
| | | | Bump snapshot version number after giving a snapshot w/bugfix to a user.
* [svn-r7944] Purpose:Quincey Koziol2003-12-133-11/+78
| | | | | | | | | | | | | | | Bug fix. Description: Using a selection offset with hyperslab selections in chunked datasets was getting into an infinite loop and hanging the application. Solution: Apply the selection offset to the hyperslab selection properly. Platforms tested: FreeBSD 4.9 (sleipnir) w & w/o parallel h5committest
* [svn-r7942] Purpose:Quincey Koziol2003-12-121-1/+4
| | | | | | | | | | Bug fix/code cleanup Description: Add MPE information for new H5I functions. Platforms tested: Eyeballed - very minor
* [svn-r7933] Purpose:Quincey Koziol2003-12-112-34/+212
| | | | | | | | | | | Add new feature Description: Add new H5I{dec|get|inc}_ref() routines and tests for them. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r7931] Purpose:Quincey Koziol2003-12-111-11/+5
| | | | | | | | | | | | Bug fix/code cleanup Description: Make H5Pclose_class() decrement the ID's reference count to close a generic property class ID, which allows the new H5I routines to work correctly. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r7927] Purpose:Quincey Koziol2003-12-102-13/+32
| | | | | | | | | | | | Bug fix Description: Clean up a few allocations of zero-sized blocks that were detected with the new free-list assertions. Platforms tested: FreeBSD 4.9 (sleipnir) w & w/o parallel too minor to require h5committest
* [svn-r7925] Purpose:Quincey Koziol2003-12-101-0/+6
| | | | | | | | | | | Code cleanup Description: Add more assertions to detect attempted allocations of zero-sized blocks. Platforms tested: FreeBSD 4.9 (sleipnir) w & w/o parallel too minor to require h5committest
* [svn-r7919] Snapshot version 1.6 release 1 (post4)HDF Admin2003-12-081-2/+2

* [svn-r7918] Purpose:Quincey Koziol2003-12-0666-498/+506
| | | | | | | | | | | | | | | | | | | Code cleanup Description: Clean up compiler warnings, especially the 'FUNC' variable not used which comes out in production mode. Solution: Had to add a new FUNC_ENTER_NOAPI_NOINIT_NOFUNC macro for those non-API functions which don't need the 'FUNC' variable defined. (This will be _so_ much easier when C99 is standard on all our supposed platforms, since it has a __FUNC__ macro... ) Platforms tested: FreeBSD 4.9 (sleipnir) too minor for h5committest (although there were lots of files changed, the change was minor in each one)
* [svn-r7916] Purpose:Quincey Koziol2003-12-061-9/+10
| | | | | | | | | | | | Bug fix Description: Make a copy of the index value for H5Giterate and use that instead of dereferencing the index pointer. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to need h5committest
* [svn-r7902] Snapshot version 1.6 release 1 (post3)HDF Admin2003-12-011-2/+2

* [svn-r7876] Purpose:Quincey Koziol2003-11-244-2/+210
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Omnibus floating-point bug fix changes Description: There are a number of problems in the floating-point conversion code that were exposed by Ray's recent int<->float checkin: - The 'my_isnan' code in test/dtypes.c was broken and would always return true. The meant that the actual values in the float<->float conversion tests were _never_ checked, hiding the other bugs included in this checkin. - A recent change I made to the type conversion code used "FLT_MIN" instead of "-FLT_MAX" for the most negative 'float' value for the double->float conversion, which meant that any the negative number that was converted from a double to a float would have been mapped to zero, essentially. - A change that Robb appeared to have made ~2.5 years ago to the "generic" float->float conversion routine appears to be incorrect and I've backed it out. - Floating-point conversions on SGI's which converted denormalized values would be mapped to zero instead of being propertly preserved in the new type. This was addressed by an SGI-specific system call to prevent the behavior. Solution: Described above, generally. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest Misc. update: release_docs/RELEASE update forthcoming...
* [svn-r7874] Snapshot version 1.6 release 1 (post2)HDF Admin2003-11-241-2/+2

* [svn-r7861] Purpose:Quincey Koziol2003-11-204-0/+37
| | | | | | | | | | | | | | | | | Bug fix Description: Our previous "optimization" of metadata writing which only wrote metadata from one process was abusing MPI-I/O and after some consultation with Rob Ross and Rajeev Thakur, Albert & I have come up with a solution... Solution: Instead of only writing from one process, issue a collective write operation with all processes, for metadata writes. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r7855] Snapshot version 1.6 release 1 (post1)HDF Admin2003-11-171-2/+2
|
* [svn-r7846] Purpose:Quincey Koziol2003-11-131-2/+1
| | | | | | | | | | | | | | | | Bug fix. Description: The new routines added for H5MM_[m|c]alloc were causing the function stack code to infinitely recurse while allocating room for the thread-specific information (when thread-safety was turned on). Solution: Call HDmalloc directly instead of H5MM_malloc Platforms tested: FreeBSD 4.9 (sleipnir) Changed are not tested in h5committest
* [svn-r7844] Purpose:Quincey Koziol2003-11-136-230/+454
| | | | | | | | | | | | | | | | | | | Bug fix Description: Variable length strings and sequences with NULL pointers were not handled by library, causing problems access the data. This also affected fill values for variable-length datatypes. Solution: Address the issues in the library by detecting NULL sequences/strings and avoid trying to convert them. Patched up dumper to display NULL sequences/strings. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r7837] Purpose:Quincey Koziol2003-11-121-12/+15
| | | | | | | | | | | Bug fix. Description: Skip over situation where malloc(0) might occur. Platforms tested: IBM p690 (copper) too minor to require h5committest
* [svn-r7830] Purpose:Quincey Koziol2003-11-085-15/+79
| | | | | | | | | | | | | | | | | Bug fix & code cleanup Description: Allowing the library to call malloc with a size of 0 bytes causes problems for some users, so we check for allocations of 0 bytes and disallow them now. Cleaned up some code which could call malloc with 0 size. Changed some code calling HDmalloc directly to call H5MM_malloc(), which allows us to check for 0 sized allocations. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7828] Purpose:Quincey Koziol2003-11-081-6/+6
| | | | | | | | | | | | Bug fix Description: Make --disable-hsizet work properly again by fixing a couple of tests and correcting the definition of SSIZET_MAX. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest not used, as it doesn't test this configuration.
* [svn-r7825] Purpose:Quincey Koziol2003-11-071-53/+96
| | | | | | | | | | | | | | | Code optimization Description: Improved integer & floating-point datatype conversions by removing some corner cases. Got rid of algorithm which walked the buffer of elements to convert backwards, switching to algorithm which computes the non-overlapping space in the buffer and repeatedly converts it in the forward direction. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest Cray SV1 & T3E (T90 is not accessible)
* [svn-r7821] Purpose:Quincey Koziol2003-11-061-8/+1
| | | | | | | | | | | | Bug fix Description: Don't check the number of szip parameters set during the "can apply" and "set local" callbacks, be safe about setting the parameters instead. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7819] Purpose:Quincey Koziol2003-11-062-4/+4
| | | | | | | | | | | Warning cleanup Description: Make a parameter 'const' to clean up a warning during compiles. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest

* [svn-r7795] Purpose:Quincey Koziol2003-10-301-203/+107
| | | | | | | | | | | | | | | | | | Code cleanup & simplification Description: Replace [non-working] code in routine to build up an MPI derived type for a hyperslab selection that was supposed to "flatten" out contigous blocks with code that uses a selection iterator (which _does_ have working "flattening" code). Remove "contiguous hyperslab" code for MPI selections as it is unnessary now. Platforms tested: FreeBSD 4.9 (sleipnir) w & w/o parallel Linux 2.4 (verbena) w/FORTRAN & C++ Solaris 2.7 (arabica) w/64-bit
* [svn-r7790] Purpose:Quincey Koziol2003-10-295-221/+68
| | | | | | | | | | | | | | | Bug fix & code cleanups Description: Change our use of MPI derived datatypes to not create datatypes with "0-sized" lengths, which causes the LANL Q machine to hang. Also, get rid of "prefer MPI derived datatypes" environment variable since it has no advantage. Platforms tested: FreeBSD 4.9 (sleipnir) w & w/o parallel h5committest
* [svn-r7768] Purpose:Quincey Koziol2003-10-281-36/+11
| | | | | | | | | | | | | Code cleanup Description: Untwist the last few sections of code before starting on fixing the problems with reading off the end of the file in earnest. Platforms tested: FreeBSD 4.9 (sleipnir) FreeBSD 4.9 (sleipnir) w/parallel h5committest not necessary - parallel only changes
* [svn-r7766] Purpose:Quincey Koziol2003-10-282-79/+105
| | | | | | | | | | | | | Code cleanup Description: More collective/independent cleanups to straighten out code contortions. Platforms tested: FreeBSD 4.9 (sleipnir) FreeBSD 4.9 (sleipnir) w/parallel Linux 2.4 (verbena) w/fortran & C++ Solaris 2.7 (arabica) w/64-bit extensions enabled
* [svn-r7764] Purpose:Quincey Koziol2003-10-284-8/+12
| | | | | | | | | | | | | | | | | Bug fix Description: Code was using an internal DXPL with collective I/O turned on during independent I/O operations to fill dataset on disk. Solution: Switched to internal DXPL with independent I/O Platforms tested: FreeBSD 4.9 (sleipnir) FreeBSD 4.9 (sleipnir) w/parallel Linux 2.4 (verbena) w/fortran & C++ Solaris 2.7 (arabica) w/64-bit extensions enabled
* [svn-r7760] Purpose:Quincey Koziol2003-10-281-2/+2
| | | | | | | | | | | | | | Fix serial build Description: I accidentally put the "use_par_opt_io" variable in an #ifdef PARALLEL section. Solution: Hoist it out of parallel section Platforms tested: Eyeballed it - very trivial
* [svn-r7755] Purpose:Quincey Koziol2003-10-274-34/+64
| | | | | | | | | | | | | Code cleanup Description: Straighten out more goofiness in the MPI code dealing with collective I/O transfers - mostly make certain that a view is set if-and-only-if collective I/O is occurring on raw data (and vice versa for views and independent I/O) Platforms tested: FreeBSD 4.9 (sleipnir) w/parallel too minor to repquire h5committest
* [svn-r7747] Purpose:Quincey Koziol2003-10-272-116/+0
| | | | | | | | | | | | Code cleanup Description: Remove collective parallel I/O checking code, now that it's impossible to get into this code with collective access enabled. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7745] Purpose:Quincey Koziol2003-10-271-108/+54
| | | | | | | | | | | | | | Code cleanup Description: More refactoring on setup of MPI-IO parameters: hoisted the code to change the transfer mode from collective to independent up into the H5D_read and H5D_write routines, instead of duplicating it inside each of the chunk/contig read/write routines. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7743] Purpose:Quincey Koziol2003-10-272-87/+61
| | | | | | | | | | | | Code cleanup Description: Clean up setup code for collective I/O transfers to make the logic more obvious. Platforms tested: FreeBSD 4.9 (sleipnir) too minor for h5committest
* [svn-r7735] Purpose:Quincey Koziol2003-10-251-30/+44
| | | | | | | | | | | | | | | | | Bug fix Description: Single hyperslab selections (which were set with only one call to H5Sselect_hyperslab) that had dimensions that could be "flattened" but were interspersed with dimensions that could not be flattened were not correctly handled, causing core dumps. Solution: Re-work "flattening" code to handle this case properly. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r7726] Purpose:Quincey Koziol2003-10-245-209/+316
| | | | | | | | | | | | Code cleanup Description: Refactored handlier of VFL drivers in file access and data transfer property lists in order to simplify and unify the code dealing with them. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r7723] Purpose:Quincey Koziol2003-10-241-2/+2
| | | | | | | | | | | | Bug fix Description: Change "H5_HAVE_PARALLEL" to "H5_HAVE_FPHDF5" around VFL ID, to prevent daily builds from failing. Platforms tested: FreeBSD 4.9 (sleipnir) w/parallel too specialized to require h5committest
* [svn-r7681] Purpose:Quincey Koziol2003-10-211-209/+164
| | | | | | | | | | | | | | | Bug fix Description: Remove the [duplicated] native C9x datatype initializatin code from H5T.c and let the automatically generated code in H5Tinit.c handle initializing them, if they are allowed by the compiler. Platforms tested: FreeBSD 4.9 (sleipnir) Linux 2.4 (verbena, eirene) probably should be h5committested, but it's late and I'm fairly certain this will fix the problem... :-/
* [svn-r7676] Purpose:Quincey Koziol2003-10-201-2/+2
| | | | | | | | | | | | | | | Bug fix Description: Avoid "OPAQUE" symbol in template macro invocation, since it's already defined as a macro on Windows. Solution: OPAQUE -> OPAQ Platforms tested: FreeBSD 4.9 (sleipnir) Windows ? (Pedro's machine :-)
* [svn-r7672] Purpose:Quincey Koziol2003-10-203-1654/+688
| | | | | | | | | | | | | | Code cleanup/refactoring/potential bug fix Description: Migrate "template macro" changes from development branch back into this branch, since they give about a 20% speedup for integer & floating-point type conversions. The also avoid a potential alignment bug on the Crays... Platforms tested: FreeBSD 4.9 (sleipnir) h5committest not necessary, since the changes are already verified in the development branch.
* [svn-r7670] Purpose:Quincey Koziol2003-10-201-12/+8
| | | | | | | | | | | | | | | | | | Bug fix Description: In certain [very rare] circumstances, the object header for a named datatype can preempt the object header for the dataset using the named datatype, causing the library to die an ugly death. Solution: "Protect" the object header for the dataset (taking it out of the cache) before getting the information about it's named datatype, avoiding the cache deadlock. Platforms tested: FreeBSD 4.9 (sleipnir) Windows ? (at Boeing site)
* [svn-r7661] Purpose: Maintenance after 1.6.1 releaseElena Pourmal2003-10-171-2/+2
