* [svn-r12848] Description:Quincey Koziol2006-11-024-148/+256
| | | | | | | | | | | | | | Change H5Pset_elink_prefix to be more similar to rest of library and make a copy of the string passed in. Change H5Pget_elink_prefix to be link rest of library routines that query a string.

| | | | | | | | | | | | | Finish refactoring job on the library's property list class initialization code, so that the library determines the parent class dependencies at run-time, eliminating the need for developers to initialize the classes in a particular order. Also eliminates some more redundant code...

* [svn-r12842] Description:Quincey Koziol2006-11-0248-2247/+2935
| | | | | | | | | | | | | | | | Refactor generic property list initialization code to put property list specific routines in property list modules, instead of scattered to the four winds. Also, introduce property list class initialization objects, to make adding new property list classes in the library easier. Fix daily test failure by using H5Pget_elink_prefix() API routine instead of looking at the "raw" generic property list information.

| | | | | | | | | | the size of the linkval buffer, per Elena and Frank's suggestions while revising the documentation. Added error checking using this size, as well as a couple of tests. Tested on juniper, kagiso, and sol.
* [svn-r12830] Description:Quincey Koziol2006-10-305-90/+203
| | | | | | | | | Finish internal work necessary to track creation order in v2 B-tree when group is in "dense" storage form. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)

* [svn-r12825] Description:Quincey Koziol2006-10-3010-20/+388
| | | | | | | | Rudimentary support for creating creation order index (but not inserting links in it yet). Testedon: Mac OS X/32 10.4.8 (amazon)
* [svn-r12824] O_DIRECT flag was accidentally commented out in previous ↵Raymond Lu2006-10-301-1/+1

* [svn-r12823] Description:Quincey Koziol2006-10-299-112/+496
| | | | | | | | | | | | | Add support for compress heap blocks in "managed" heaps. Also, fix bug when the first direct block moves between having a parent and not having one (and vice versa), which occurs when the heap moves between having a direct root block and having an indirect root block. Tested on: FreeBSD 4.11 (sleipnir) w/threadsafe Linux/32 2.4 (heping) w/C++ & FORTRAN Linux/64 2.4 (mir) w/build-all & 1.6 compat

| | | | | | made the test more complete by writing two data sets. One is aligned, and the other isn't.
* [svn-r12821] Description:Quincey Koziol2006-10-283-38/+38
| | | | | | | | | Clean up compiler warnings, esp. on 64-bit Linux boxes. Tested on: FreeBSD/32 4.11 (sleipnir) w/threadsafe Linux/32 2.4 (heping) w/C++ & FORTRAN Linux/64 2.4 (mir) w/build-all & 1.6 compat
* [svn-r12820] Added fragmental copy buffer to H5FD_direct_write. This buffer ↵Raymond Lu2006-10-272-92/+136
| | | | | | | size is set through H5Pset_fapl_direct. It's been added to H5FD_direct_read in the previous checkin. Still, a test is needed at later checkin.
* [svn-r12809] Purpose:Albert Cheng2006-10-251-2/+4
| | | | | | | | | | | | | | Bug fix. Description: H5FD_get_vfd_handle() would return okay even if an VFD did not have the get_vfd_handle callback function defined. Solution: Return failure if get_vfd_handle function is not defined. Tested: in heping and copper.
* [svn-r12806] Description:Quincey Koziol2006-10-245-94/+189

* [svn-r12805] Description:Quincey Koziol2006-10-231-2/+2
| | | | | | | | Fix off-by-one memory error when retrieving I/O pipeline filter's name. Tested on: Linux/64 2.4 (mir) FreeBSD/32 4.11 (sleipnir)
* [svn-r12803] Description:Quincey Koziol2006-10-2321-645/+790
| | | | | | | | | | | | | | Finish new version of the I/O pipeline message, which is much smaller than the previous version. This version is used with the "use the latest version of the format" flag. Closed several memory leaks/overruns (found with valgrind). Also, lots of compiler & formatting cleanups. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12802] Description:Quincey Koziol2006-10-232-23/+27

* [svn-r12801] Description:Quincey Koziol2006-10-233-335/+478
| | | | | | | | | | | | Fix several errors in the "latest version" of the object header format changes and enable the new version when requested now. Clean up several confusing or duplicated sections of code. Tested on: Linux/32 2.4 (heping) Linux/64 2.4 (mir) FreeBSD/32 4.11 (sleipnir)
* [svn-r12792] Fixed a Makefile.am to clean up a test file generated by the ↵James Laird2006-10-205-889/+890
| | | | | | | | | | | Packet Table compression test. Tested that the file is removed on juniper and heping. Running reconfigure also regenerated the H5E* files (I think this means somebody updated these files but didn't run reconfigure).
* [svn-r12788] Enable the algorithm of Direct driver to read data in fragment ↵Raymond Lu2006-10-191-36/+76
| | | | | | | | from file. If the application requests large data from file, to avoid using too much of memory for copying data from library's own aligned buffer to application's (unaligned) buffer, this step is done in fragment. The next step checkin is to handle writing data in fragment.
* [svn-r12783] Took out the function H5FD_direct_alloc that was added ↵Raymond Lu2006-10-191-47/+1
| | | | | | | yesterday. This function would be redundant because the allocation function in H5FD.c H5FD_real_alloc actually has handled the aligned allocation.
* [svn-r12777] Added support to aligned file space allocation. The alignment ↵Raymond Lu2006-10-181-1/+47
| | | | | | should be set through H5Pset_alignment.
* [svn-r12776] The internal change is to make the 3 parameters of ↵Raymond Lu2006-10-182-24/+200
| | | | | | | | H5Pset_fapl_direct be a structure and passed through driver info functions in H5FD_direct_open, H5FD_direct_read, and H5FD_direct_write. The external change is to add a new API function H5Pget_fapl_direct to query 3 control values, the memory boundary, file system block size, and the maximal buffer size for copying data.
* [svn-r12774] Modified flush code in the metadata cache to allow it toJohn Mainzer2006-10-1812-178/+995
| | | | | | | | | | | | | | | | | handle flush callbacks which can dirty other entries, and resize and/or rename the target entry. This feature is needed by the fractal heap code. Also added associated test code. H5Commit tested. Test failed on heping, but the error appears to be a syntax error in an un-related file. Tests on copper & sol passed, along with tests on phoenix.
* [svn-r12771] Description:Quincey Koziol2006-10-174-151/+453
| | | | | | | | | | | | | | | | | More fixes to make the I/O & memory operations more efficient when loading & flushing object header chunks. Add in concept of a chunk having a "gap" at the end - unused space that is not large enough to hold a full null message that describes it. Clean up formatting a bit. Latest version of object header format not enabled yet, still working on a few bugs... Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12770] Description:Quincey Koziol2006-10-163-374/+359
| | | | | | | | | | | | | | | Overhaul usage of object header chunks to reduce I/O operations and memory allocations. The object header prefix is now stored in the first object header chunk's "image" in memory. Also, lots of formatting cleanups. Taught h5debug tool about new object header format (which isn't enabled just yet). Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12769] Description:Quincey Koziol2006-10-161-53/+50
| | | | | | | | | | | Move object header creation past several internal possibilities for errors, making the routine more resistant to errors encountered. Also, various formatting/compiler warning cleanups. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12768] Description:Quincey Koziol2006-10-166-26/+26
| | | | | | | | | | Add 'initval' parameter to "lookup3" checksum routine (and implicitly to the metadata checksum routine), to allow chaining several checksums together easily (which isn't used by these modules, but will be used in my next checkin) Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12767] Description:Quincey Koziol2006-10-164-14/+16
| | | | | | | | Code cleanup to improve formatting & reduce compiler warnings. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12766] Made two changes to Direct I/O VFD: first added 3 parameters to ↵Raymond Lu2006-10-162-124/+170
| | | | | | | | H5Pset_fapl_direct to control memory boundary, file block size, and maximal copy buffer size; second in H5FD_direct_write and H5FD_direct_read, the library checks whether data buffer is aligned. If it is, then write and read the data directly instead of making a copy buffer.
* [svn-r12761] Description:Quincey Koziol2006-10-166-388/+444
| | | | | | | | | | Refactor object header macros, in preparation for updating the format. Tested on: Mac OS/PPC 10.4.8 (amazon) FreeBSD/32 4.11 (sleipnir) w/thread-safe Linux/32 2.4 (heping) w/C++ & FORTRAN Linux/64 2.4 (mir) w/1.6 compat & build-all
* [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
* [svn-r12756] Description:Quincey Koziol2006-10-127-113/+94
| | | | | | | | | | | | | | 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)

| | | | | | posix_memalign function but causes compiling error on copper. Comment it out. It only gives a warning on SGI Altix.
* [svn-r12741] Added support for direct I/O to check-vfd. The direct VFD is ↵James Laird2006-10-106-891/+891
| | | | | | | | | | only tested if it is enabled. Added Direct VFD status to the configure summary. Removed a line left over from pablo support. Oops!
* [svn-r12740] Description:Quincey Koziol2006-10-109-391/+374
| | | | | | | | | | | 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.
