* [svn-r9342] Purpose:Quincey Koziol2004-09-3018-1365/+661
| | | | | | | | | | | | | | | | Bug fix/code cleanup Description: Clean up raw data I/O code to bundle the I/O parameters (dataset, DXPL ID, etc) into a single struct to pass around through the dataset I/O routines, since they are always passed together, until very near the bottom of the I/O stack. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Solaris 2.7 (arabica) IRIX64 6.5 (modi4) h5committest

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Purpose: Feature Description: Datatypes and groups now use H5FO "file object" code that was previously only used by datasets. These objects will hold a file open if the file is closed but they have not yet been closed. If these objects are unlinked then relinked, they will not be destroyed. If they are opened twice (even by two different names), both IDs will "see" changes made to the object using the other ID. When an object is opened using two different names (e.g., if a dataset was opened under one name, then mounted and opened under its new name), calling H5Iget_name() on a given hid_t will return the name used to open that hid_t, not the current name of the object (this is a feature, and a change from the previous behavior of datasets). Solution: Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's, and H5G_t's into a "shared" struct and a private struct. The shared structs (H5D_shared_t, etc.) hold the object's information and are used by all IDs that point to a given object in the file. The private structs are pointed to by the hid_t and contain the object's group entry information (including its name) and a pointer to the shared struct for that object. This changed the naming of structs throughout the library (e.g., datatype->size is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.

| | | | | | | | | | | | | | | | Bug fix Description: Fix for small memory leak that occurs when destroying the data transform property. Forgot to free the array of pointers to the temorary data. Solution: Freed memory. Platforms tested: sol + eirene Misc. update:
* [svn-r9312] Purpose:Quincey Koziol2004-09-231-6/+6

* [svn-r9310] Purpose:Quincey Koziol2004-09-221-0/+27
| | | | | | | | | | | | | | Code optimization Description: Avoid performing a check on the number of objects in a group (which currently involves iterating over all entries in the group's B-tree) before calling H5G_get_obj<foo>_by_idx. Instead, just have H5G_get_obj<foo>_by_idx() notice when you've walked off the end and return fail then. Platforms tested: FreeBSD 4.10 (sleipnir) h5committest
* [svn-r9297] Purpose:Albert Cheng2004-09-221-5/+10
| | | | | | | | | | | | | | | | Bug fix. Description: Code would attempt to Calloc with zero count when a simple expression that has no x term. That resulted in NULL for some platform (like AIX). That appeared as a failure treated as out of space. Solution: Checked if count is larger than 0 before making the calloc request. Platforms tested: Tested in copper (pp) where the failure appeared. Also in eirene as double check. No h5committest as the change is trivial.
* [svn-r9273] Purpose:John Mainzer2004-09-181-0/+120
| | | | | | | | | | | | | | | | | | | | | | | | | | | Port fix of parallel I/O mode confusion bug from the 1.6 tree to the 1.7 tree. Description: Collective I/O is not supported for point selections. Thus when some processes attempted I/O with point selections, and others without, some attempted collective I/O while others did independent I/O. Solution: Arranged for all processes to compare notes before starting I/O, and for all to use independent I/O if any one of them can't do collective I/O. Platforms tested: copper h5committested eirene (parallel) Misc. update:
* [svn-r9271] Purpose:Albert Cheng2004-09-171-0/+1
| | | | | | | Update for the new API, H5Pget_data_transform. Platforms tested: Copper only. No h5committest since this is trivial.
* [svn-r9267] Purpose:Leon Arber2004-09-164-111/+361
| | | | | | | | | | | | | | | | | | | Added H5Pget_data_transform Added support for polynomial data transforms Description: There is now support for polynomial data transforms (ie, (2+x)*(x-5)) instead of just linear ones. Note that, in order to compute a polynomial transform, one temporary copy of the original data must be stored for each occurence of "x" in the transform expression. This can result in very high memory usage for expressions of high order. Platforms tested: sol + eirene Misc. update:
* [svn-r9250] Purpose:Quincey Koziol2004-09-143-12/+10
| | | | | | | | | | | | | | | | | | | | Bug fix Description: Correct typedef for dataset region references to avoid struct alignment issues on Crays. Solution: Change the typedef for hdset_reg_ref_t from a struct to an array of unsigned char's of the correct size and propagate the appropriate adjustments around the code.

* [svn-r9234] Purpose:Quincey Koziol2004-09-096-99/+178
| | | | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Tweak recent "forward compatibility" changes to the H5E* API (which allowed for the old H5E API functions to remain unchanged) by allowing for the error stack callback function (H5E_auto_t) to also remain unchanged from the 1.6 branch. This required changing the H5E{get|set}_auto routines to have the old style H5E_auto_t type (which didn't have a stack ID parameter) and the new H5E{get|set}_auto_stack routines to have a newer "H5E_auto_stack_t" type (which has a stack ID parameter). This should make the H5E API changes as forwardly compatible as possible. One side-affect of this change was that it was impossible to determine if the current auto error callback was the old style (H5E_auto_t) or the new style (H5E_auto_stack_t) of callback, so a new API function (H5Eauto_is_stack) was adde to query this.

| | | | | | | | | | | | | | | | | | | | | | | | | bug fix Description: on the Cray SV1 an INT type was wrongly converted to a SHORT type by the get_native_integer function Choose the type based on the precision; this is to support cases like the Cray SV1, where the size of short is 8 but precision is 32 (e.g an INT (size 8, prec 64) would be converted to a SHORT (size 8, prec 32) if the size was the deciding factor) Solution: Platforms tested: linux solaris aix Misc. update:

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bug fix Description: Description: the dataset region reference data was not portable between the Cray T3E and other machines Solution: this was due to the fact that the buffer to store the heap ID and index was using a sizeof(int) for its size 4 is used instead of sizeof(int) to permit portability between the Crays and other machines (the heap ID is always encoded as an int32 anyway) Solution: Platforms tested: linux aix solaris Misc. update:
* [svn-r9183] Purpose: New featureRaymond Lu2004-09-0122-413/+194
| | | | | | | | | | | | Description: Restore 6 old error API functions back to the library to be backward compatible with v1.6. They are H5Epush, H5Eprint, H5Ewalk, H5Eclear, H5Eset_auto, H5Eget_auto. These functions do not have error stack as parameter. Solution: Internally, these functions use default error stack. Platforms tested: h5committest and fuss. Misc. update: RELEASE.txt
* [svn-r9172] Purpose:Albert Cheng2004-08-271-2/+2
| | | | | | | | | | | | | | | | | | | | | "bug fix" sort of. Description: The current mpicc at TG-NCSA recognizes uint64_t but not int64_t. hdf5 code rightly assumes when the unsigned type is defined, the corresponding signed type should be valid too. So, when it detected uint64_t is valid, it went ahead using int64_t which ended in compiling failure. Solution: Changed the detection to check on int64_t instead. This does not change any logic, just goes around the mpicc compiler error at TG-NCSA. Platforms tested: h5committested and tested at TG-NCSA (pp) too. Misc. update:
* [svn-r9155] Purpose:Quincey Koziol2004-08-251-2/+80
| | | | | | | | | | | | | | | Bug fix (sorta) Description: Change reading of "missing" chunks from datasets with undefined fill values to not overwrite the application buffer with random garbage from memory. Note that this is almost the same, since whatever garbage the application had in those locations will still be there... Platforms tested: FreeBSD 4.10 (sleipnir) IRIX64 6.5 (modi4) h5committested

* [svn-r9117] Purpose: Minor Bug FixRaymond Lu2004-08-191-2/+2
| | | | | | | | | | | Description: In H5O_fill_new_decode and H5O_fill_new_encode, UINT32DECODE and UINT32ENCODE were used to decode and encode message size, which is ssize_t. Solution: Change to INT32DECODE and INT32ENCODE. Platforms tested: fuss - very simple change. Misc. update:
* [svn-r9108] Purpose: Bug fixRaymond Lu2004-08-181-16/+4
| | | | | | | | | | | Description: In H5O_fill_new_decode, it tries to read message size(-1) when fill value is undefined for version 1. During UINT32DECODE, if the machine is 64-bit, a value 0x00000000ffffffff is returned, which is like a valid value. Solution: If fill value is undefined, don't read the message size, simply assign -1 to it. Platforms tested: fuss - did h5committest for v1.6 already.
* [svn-r9101] Purpose:Quincey Koziol2004-08-174-308/+278
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix Description: 1 - Dataset contiguous storage cache information had a bug where it was possible to try to access invalid cache information if the cache wasn't filled the first time it attempted to loop through the list of offset/length vectors. 2 - Additionally, the contiguous storage cache information was being used in certain circumstances from the chunked dataset I/O code path, which was generally fatal since the chunk storage and contiguous storage information were stored together in a union. Solution: 1 - Avoid special case of first trip through loop over offset/length I/O vectors and always check for the contiguous storage sieve buffer buffer being NULL. 2 - Change the union containing the chunk and contiguous storage cache information into a struct, allowing both to be used at the same time.

| | | | | | | | | | | | | | | | | | | Bug fix Description: Correct possible core dump when a datatype conversion function is registered with the library after a compound datatype has been converted (having it's type conversion information cached by the library). The compound datatype must have been created by inserting the fields in non-increasing offset order to see the bug. Solution: Re-sort the fields in the compound datatypes before recalculating the cached information when performing the conversion on them. Platforms tested: FreeBSD 4.10 (sleipnir) h5committested

| | | | | | | | | | | | Code cleanup/bug fix Description: Check for _O_BINARY being defined instead of O_BINARY, since we actually use _O_BINARY. (Note that this only affects Windows) Platforms tested: FreeBSD 4.10 (sleipnir) Not tested w/h5committest

| | | | | | | | | | | | | Bug fix Description: Correct buffer overrun in "multi" VFL driver that was writing past the end of the "driver name" buffer when encoding the driver info block for the file's superblock. Platforms tested: FreeBSD 4.10 (sleipnir) Too minor to require h5committest
* [svn-r9022] Purpose: Optimization of the cache code in H5C.John Mainzer2004-08-054-953/+1743
| | | | | | | | | | | | | | | | | | | | | | | Description: Cache was running too slowly. Solution: Added a hash table for indexing. Retained the tree, but only for dirty entries. As we need to flush dirty entries in increasing address order, this is sufficient. Updated statistics collection code for the above. Converted a number of local functions into macros to avoid the function call overhead. Added code to disable the clean and dirty LRU lists in serial mode. Updated test code to account for the above changes. Platforms tested: h5committested + serial, parallel, and fp on Eirene. Misc. update:
* [svn-r9018] Purpose:Albert Cheng2004-08-051-4/+276
| | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix (Failures when dataset size >= 1 GB, reported by Bill Loewe.) Description: In the IBM AIX system using 32bit mode, if a dataset size was 1GB or larger, when the "end" of the dataset was selected, MPI would complain it could not keep the Upper bound of a datatype within the range of MPI_Aint. This was because the old algorithm would derive the selection with extent of each row first. After all dimensions were processed, it then calculate the start position and just displace the whole MPI derived type. So, the final MPI type was actually the start position plus the whole dataset. Since the start can be as big as the whole dataset, this made the final derived twice as big as 1GB. That would hit the 2GB MPI_Aint range limit in the 32 bit mode. Solution: Use a different algorithm to include the start position in the defining of MPI type for each dimension. When all dimensions are processed, the MPI type represents the selection exactly.

* [svn-r8969] Purpose:Quincey Koziol2004-07-302-53/+35
| | | | | | | | | | | | | | | | | | | | | | | | Bug fix. Description: Address two problems: - The computation of the scanline in the szip filter was being performed in the "can apply" callback routine instead of the "set local" routine. - The routine which allocated all the chunks for an entire dataset (which is invoked when the allocation time is early or late, rather than incremental) wasn't recording a failed filter in the information for the chunk, causing the library to believe that the chunk had the filter applied when it really hadn't. Solution: - Move the scanline computation to the "set local" callback. - Record the filter mask with each chunk created when allocating them. Platforms tested: FreeBSD 4.10 (sleipnir) w/szip Too obscure to require h5committest

| | | | | | | | | | | | | | | | Purpose: Bug fix Description: When a simple dataspace is created, its extent should be set before using it, or it will silently function as a NULL dataspace. Solution: Added checks on user-supplied dataspaces. Now dataspaces without extents set will throw errors; users must explicitly set a dataspace to be NULL. Platforms tested: sleipnir, windows
