* [svn-r12760] Description:Quincey Koziol2006-10-161-3/+253
| | | | | | | | | | | | Speculatively attempt to read in the entire first chunk in object header with the object header prefix. If successful (which it is most of the time), this reduces by 1 the # of I/Os required to read in the object header. Since the object header typically was taking 2 I/Os, this should cut the number of I/O operations when opening an object's header in half. Tested on: FreeBSD/32 4.11 (sleipnir) w/threadsafe Linux/32 2.4 (heping) w/C++ & FORTRAN

| | | | | | | | | | | | | | Clean up some object header code in advance of more major changes in the near future. Fix small initialization error in attribute message name buffer copy. Tweak down the default # of messages for new object headers. Tested on: FreeBSD/32 4.11 (sleipnir) w/threadsafe Linux/32 2.4 (heping) w/FORTRAN & C++ Mac OS/32 10.4.8 (amazon)

| | | | | | | | | | | Update datasets and the layout, attributes and fill-value object header messages to use the latest version of the file format flag. Tested on: FreeBSD 4.11 (sleipnir) Linux/64 2.4 (mir) Linux/32 2.4 (heping)
* [svn-r12739] Added Direct I/O driver to VFD. It's only supported by SGI ↵Raymond Lu2006-10-1011-10/+1056
| | | | | | | | | | Altix (cobalt). There's a configure option --enable-direct-vfd/--disable-direct-vfd to enable/disable Direct I/O support. The default is enabled. There's a small test in test/vfd.c. Another way to test it is to set environment variable HDF5_DRIVER to "direct" and run "make check" in the test/ directory. There'll be some further improvement in the following checkin including allowing user to provide memory boundary value, file block size, and copying buffer size.
* [svn-r12738] Description:Quincey Koziol2006-10-102-2/+2
| | | | | | | | Tweak down some of the static array definitions for new & re-loaded object header data structures, to reduce memory use in common cases. Tested on: Linux/32 2.6 (chicago)
* [svn-r12736] Description:Quincey Koziol2006-10-098-358/+340
| | | | | | | | | | | | | | | | | | | Add "use the latest format" support for dataspace object header encode/ decode routines and clean up format a bit for the latest format (new to 1.8.x releases) Remove storing 'perm' parameter for array datatypes in memory and the file, and add test to make certain that if any user applications are attempting to store them, we get some reports back. (Should be unlikely, since the RefMan says that the parameter is not implemented and is unsupported). Carry those changes into the tests, etc. Clean up a bunch more compiler warnings. Tested on: FreeBSD/32 4.11 (sleipnir) w/threadsafe Linux/32 2.4 (heping) w/FORTRAN & C++ Linux/64 2.4 (mir) w/enable-1.6-compat

| | | | | | | 2. Using H5Dmpio_Debug macro to reflect the debugging information of new parallel IO supports. They are very minor changes. Tested at heping. t_pflush2 failed. Others passed.
* [svn-r12723] Fix a bug where return values were overwritten in H5F_dest, and ↵James Laird2006-10-051-1/+13
| | | | | | | | | | | | | | another bug exposed by that one in which closing a read/write file ID wouldn't flush the cache if there was another file handle open. This caused problems when the second file handle was read-only; neither would actually flush the cache. Now all read/write file handles flush the cache when the close, but only when the file is going to be destroyed is the cache destroyed. This way read-only file handles keep the cache open but it is always clean. Tested on mir, heping, sol, and copper (parallel)

| | | | | | | | | | | | utility and quote its arguments. Also checks for the 'socket' library on Solaris. If this patch passes the Daily Tests and makes the user happy, I'll port it back to the 1.6 branch. Tested on mir and sol.
* [svn-r12712] Description:Quincey Koziol2006-10-031-196/+283
| | | | | | | | | | Finish 'use the latest version of the format' changes to the datatype object header message. Compound and enumerated types will now be encoded more efficiently by packing the field names & member offsets better. Tested on: Linux 2.6/32 (chicago) Linux 2.6/64 (chicago2)
* [svn-r12708] Description:Quincey Koziol2006-10-0313-332/+547
| | | | | | | | | | | | | | | | | | | Add the "use the latest version of the format" support to datatype messages. And a regression test to check that it's working. Also, found that we have been over-allocating space for compound datatype messages (when they have array datatypes or can use the latest version of the format) and trimmed the size back. Clean up datatype & dataspace encode/decode routines by having them allocate & release "fake" file structures, which gets them out of needing to "know" about the internals of file structures. Other minor whitespace/formatting cleanups, etc. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12707] Description:Quincey Koziol2006-10-025-66/+118
| | | | | | | | | Further minor modifications to the file format for tracking links in groups. This is tentatively the "final" file format for groups. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)

| | | | | | | | | | | | int64_t is only defined in H5private.h. Moved definition of int64_t from H5private.h to H5public.h as a temporary solution. Tested on heping and Windows (windows also needed H5Gdense.c and H5Gbtree2.c to be added to hdf5 project).
* [svn-r12702] Description:Quincey Koziol2006-10-022-59/+79
| | | | | | | | | | | | | | | | | Add test to fractal heaps to exercise issues with opening the same heap through two different file handles. Fix issues with file handle contexts in metadata cache callbacks for heap components. Fix bug in file close handling where cached information was being invalidated even when another file handle was open to the file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | File format is not stable, don't keep files produced! Description: First stage of checkins modifying the format of groups to support creation order. Implement "dense" storage for links in groups. Try to clarify some of the symbols for the H5L API. Add the H5Pset_latest_format() flag for FAPLs, to choose to use the newest file format options (including "dense" link storage in groups) Add the H5Pset_track_creation_order() flag for GCPLs, to enable creation order tracking in groups (although no index on creation order yet). Remove --enable-group-revision configure flag, as file format issues are now handled in a backwardly/forwardly compatible way. Clean up lots of compiler warnings and other minor formatting issues.

* [svn-r12692] Removed code that was used to support lazy allocation of file spaceJames Laird2006-09-284-89/+2
| | | | | | | since HDF5 no longer allocates file space lazily. Tested on mir; should be only a cleanup, since the code isn't called from anywhere.
* [svn-r12686] Added compression to Packet Tables. Now both C and C++ packet ↵James Laird2006-09-261-0/+1
| | | | | | | | | | | | | | | | tables have an extra parameter that sets the deflate filter. Added tests, made examples use the new APIs. Cleaned up include files a little and removed some casts that I hope are superfluous. If anybody encounters strange errors in the packet table tests where the chunk size is set to some extremely large value, please let me know, but I was unable to reproduce this error on any system. Tested on mir, heping, sol, juniper, VS 6.0. Looked for the chunk size error on several other systems a month or two ago.

* [svn-r12661] Description:Quincey Koziol2006-09-122-10/+183
| | | | | | | | | | | Add 'loookup3' checksum routine and switch to using it for metadata checksums - it's just as "strong" as the CRC32 and about 40% faster in general (with some compiler optimizations, it's nearly as fast as the fletcher-32 algorithm). Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)

* [svn-r12656] Description:Quincey Koziol2006-09-115-53/+156
| | | | | | | | | | | | | | | Add "use the latest version of the file format" flag to the file access property list and internal file data structures. Fix bug where metadata block size was retrieved instead of the small data block size. Categorize property list routine prototypes in the public header file. Tested on: Mac OS/PPC 10.4 (amazon) Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12655] Description:Quincey Koziol2006-09-1111-907/+1275
| | | | | | | | | | | | Add "op" routine to perform operation on heap object "in situ", to allow for faster operations on dense links during B-tree traversal & lookup. Refactor the "read" routine to use the internal version of the "op" routine, to keep the code duplication as low as possible. Tested on: Mac OS X.4/PPC (amazon) Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)

* [svn-r12649] Description:Quincey Koziol2006-09-053-12/+128
| | | | | | | | | | | | Add a CRC algorithm to the library, initially for "small" (<256 byte) metadata blocks. Update checksum tests to verify it's working correctly. Tested: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2) (Will be testing on more platforms after checkin)
* [svn-r12648] Description:Elena Pourmal2006-09-051-1/+2
| | | | | | | | | | | | | | This is VMS problem only. H5Dremove_all function was modified to use HDremove. Since HDremove is defined as HDremove_all in H5private.h, function became recursive causing all kinds of resource problems. Solution: Use "remove" instead. Platforms tested: VMS server
* [svn-r12647] Description:Quincey Koziol2006-09-051-2/+2
| | | | | | | | | Eliminate redundant "B-tree type" byte from internal & leaf nodes. May possibly improve B-tree density in rare circumstances... Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)

* [svn-r12644] Description:Quincey Koziol2006-09-058-650/+299
| | | | | | | | | | | | | Improve density of the B-tree further. For greater depths of B-trees, the gains are over 100%... Also, don't split internal nodes with 3->4 splits, use a 1->2 split instead, so that the density of the nodes around a split is maximized.

* [svn-r12638] Description:Quincey Koziol2006-09-047-393/+382
| | | | | | | | | | | | Split edge nodes in the tree with a 1->2 node split, instead of a 2->3 node split, which creates a more dense tree when a pattern of record insertions occurs (because it leaves behind full nodes instead of 2/3 full nodes).
