* [svn-r8846] Purpose:Quincey Koziol2004-07-0911-43/+130
| | | | | | | | | | | | | | | | | | Bug fix Description: The "shared" raw B-tree node can get freed before all the B-tree nodes had been flushed out to disk and released by the cache. Solution: Implement a simple reference counting wrapper for objects in the library and use it to hold the shared raw B-tree nodes so they aren't freed before all references to them in memory are released. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) IRIX64 6.5 (modei4)

* [svn-r8824] Purpose:Quincey Koziol2004-07-0710-416/+405
| | | | | | | | | | | | | | | Code optimization Description: Since the raw B-tree nodes are the same size and only used when reading in or writing out a B-tree node, move raw B-tree node buffer from being per node to a single node that is shared among all B-tree nodes of a particular tree, freeing up a lot of space and eliminating lots of memory copies, etc. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8819] Purpose: Potential bug fixRaymond Lu2004-07-072-9/+12
| | | | | | | | Description: In H5Fget_filesize, file size was returned as haddr_t. Solution: Return file size as hsize_t and parameter for Fortran. Platforms tested: eirene
* [svn-r8808] Purpose:Quincey Koziol2004-07-051-68/+58
| | | | | | | | | | | | Code optimization Description: Don't copy layout information, just point to existing information. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest

* [svn-r8775] James Laird2004-06-301-0/+4
| | | | | | | | | | | | | | | | | | | Purpose: Fixed a bug that broke daily tests. SZIP now always uses K13 compression. Description: When configured with the --srcdir option, dsets test would look for a test file in the same directory as the test, instead of in the directory that contains the source files. SZIP never needs to use CHIP compression, so the option to set this flag instead of K13 compression has been removed. Platforms tested: Copper
* [svn-r8771] Purpose: Update for new function.Raymond Lu2004-06-301-0/+1
| | | | | | | | Description: Forgot to add new function H5Fget_name for MPE. Solution: Simple define color_H5Fget_name as 'red' in this file. Platforms tested: Very simple change. No test needed.
* [svn-r8770] Raymond Lu2004-06-302-0/+53
| | | | | | | | | | | Purpose: New feature and its test Description: Added API H5Fget_name. It returns the name of file by object ID(file, group, dataset, named datatype, attribute) which belongs to the file. filename.c tests this function. Platforms tested: h5committest Misc. update: MANIFEST, RELEASE.txt

| | | | | | | | | | | | | | | | | | | Purpose: Handled SZIP without the encoder present. Description: It is now an error for a user to try to create, extend, or write to a dataset without the encoder present in their SZIP library. Added H5Zget_filter_info to provide users with a way to query HDF5 about the presence (or lack thereof) of the SZIP encoder. Platforms tested: Windows Verbena Arabica Copper Misc. update:
* [svn-r8751] Purpose: Bug fixRaymond Lu2004-06-281-0/+1
| | | | | | | | Description: Forgot to add H5Fget_filesize to H5MPprivate.h for MPE. Solution: Define color_H5Gget_filesize as "red". Platforms tested: Tested v1.7 on copper. Simple change.

* [svn-r8726] Purpose:Quincey Koziol2004-06-232-13/+42
| | | | | | | | | | | | Refactor bug fix Description: Make bug fix for detecting the type of a soft link more general by registering an "isa" function for soft links. Platforms tested: FreeBSD 4.10 (sleipnir) Too minor to require h5committest
* [svn-r8723] Purpose: Bug fix and test.Raymond Lu2004-06-221-1/+10
| | | | | | | | | | | | | | | Description: Function H5Gget_objtype_by_idx failed to handle soft link object. The library returned object type by calling H5G_get_type through H5B_iterate. But H5G_get_type only deals with objects with valid header address which soft link doesn't have. Solution: In H5G_node_type, make soft link a special case by checking if the object type is H5G_CACHED_SLINK. Also added a test of soft and hard links to titerate.c Platforms tested: eirene and copper(tested h5committest for v1.7)

* [svn-r8699] Purpose: Bug fix and new test.Raymond Lu2004-06-172-2/+2
| | | | | | | | | | Description: A user reported a bug on Windows when writing data of array data type of compound type with variable-length type. I didn't see any problem on Unix. But Purify revealed some memory errors and leaks. Solution: Fixed memory leaks and added new test for it. Platforms tested: h5committest.
* [svn-r8697] Purpose:Quincey Koziol2004-06-163-20/+55
| | | | | | | | | | | | | | | | | Code optimizations Description: Eliminate memset() call in H5S_set_extent_simple(). Use malloc() instead of calloc in H5B<mumble>. Change global heap code to track heap objects that are in use in order to allocate new objects more quickly and also to avoid memset() and calloc() calls. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest

* [svn-r8684] Purpose:Quincey Koziol2004-06-1415-498/+491
| | | | | | | | | | | | | Code optimization Description: Use 'size_t' instead of 'hsize_t' to track the number of elements in memory buffers, especially for type conversion. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8682] Purpose: Take out unnecessary stepRaymond Lu2004-06-141-4/+0
| | | | | | | | | Description: I put function call of H5T_lock in H5T_open in last checkin. It's unnecessary. Solution: Take out. Platforms tested: eirene(simple change).
* [svn-r8680] Purpose:Quincey Koziol2004-06-141-16/+31
| | | | | | | | | | | | | Code optimization Description: Detect when a default property list is being used and just copy over the default VL allocation properties, instead of querying for them. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8678] Purpose:Quincey Koziol2004-06-1410-283/+186
| | | | | | | | | | | | | | | | | | | Code cleanup & optimization Description: Remove old structures that used a union to store information about the dataspace extent and just store the information directly in the dataspace extent itself. Remove ifdef'd references to permutation ordering in dataspaces. We'll definitely need more than this code if/when we implement this feature. Change allocation of dataspace information from calloc() to malloc(). Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8676] Purpose:Quincey Koziol2004-06-136-358/+310
| | | | | | | | | | | | | | | Code optimization Description: Using existing dataspace extent copying routine instead of duplicating the code (more slowly). Also, back-port improvements to the dataspace message reading which clean up the clean and centralize operations. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8674] Purpose:Quincey Koziol2004-06-1315-490/+565
| | | | | | | | | | | | | | | | | | Code optimization Description: Revised dataspace selections to use a more "object oriented" mechanism to set the function pointers for each selection and selection iterator. This reduces the amount and number of times that dataspace selection info has to be copied. Additionally, change hyperslab selection information to be dynamically allocated instead of an inline struct. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8671] Purpose:Quincey Koziol2004-06-133-16/+128
| | | | | | | | | | | | | Code optimization Description: Avoid a memory copy by directly reading from the variable-length sequence buffer when there is no type conversion on the way to disk. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8669] Purpose:Quincey Koziol2004-06-131-54/+63
| | | | | | | | | | | | | | Code optimization Description: Avoid running conversion routine when it's a noop. Also, pick a minimum size for the variable-sized sequence conversion buffer, instead of allocating lots of small buffers. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel
* [svn-r8667] Purpose:Quincey Koziol2004-06-135-296/+324
| | | | | | | | | | | | | | | | Code optimization Description: Restructure conversion loop of variable-length objects to avoid walking through memory backwards and allocating as many temporary buffers. (This uses the optimized method used in the atomic type conversions). Also bring back another optimization for variable-length datatypes that avoids querying the DXPL so many times. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8665] Purpose:Quincey Koziol2004-06-125-380/+694
| | | | | | | | | | | | | | Code optimization Description: Allow global heap collections to grow in size (up to a 64K limit) if they are able to. This allows them to grow to a more reasonable size than the 4K minimum size. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest

| | | | | | | | | | | Code optimization Description: Eliminate redundant memset() when creating chunk map structure. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel
* [svn-r8649] Purpose:Quincey Koziol2004-06-102-14/+6
| | | | | | | | | | | | | Code optimization Description: Eliminate some operations through temporary variables in H5F_addr_encode. Eliminate some redundant memset()'s of structures that will be completely overwritten in the variable-length datatype code. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel
* [svn-r8640] Purpose:Quincey Koziol2004-06-091-1/+1
| | | | | | | | | | | | Code optimization Description: Call malloc() instead of calloc() for data structure that we completely initialize. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel
* [svn-r8637] Purpose:Quincey Koziol2004-06-091-37/+64
| | | | | | | | | | | | Code optimization Description: Don't allocate conversion buffer larger than the user's buffer. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel too minor to require h5committest
* [svn-r8631] Purpose:Quincey Koziol2004-06-091-1/+0
| | | | | | | | | | | | | | | | | Bug fix Description: Correct potential file corruption from mis-setting the metadata accumulator address. (Bugfix contributed by Sean Monner <seanm@quadrus.com>) Solution: When the new metadata overlaps with the end of the metadata accumulator and the accumulator grows in size, don't reset the address of the accumulator, since it hasn't moved. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r8626] Purpose:Quincey Koziol2004-06-082-2/+39
| | | | | | | | | | | | | | | Code optimization Description: Avoid pushing errors on error stack when an object is not found in a B-tree. Sometimes we are just checking if the object exists before we insert it into the B-tree and the higher levels in the library should be responsible for determining if not finding the object in B-tree is really an error. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel too minor to require h5committest
* [svn-r8624] Purpose:Quincey Koziol2004-06-081-6/+17
| | | | | | | | | | | | | Code optimization Description: Use default dataset transfer property list for internal metadata I/O operations when parallel I/O is disabled. This avoids multiple copies of the properties being made when the information is not needed. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel)
