* [svn-r12661] Description:Quincey Koziol2006-09-121-0/+30
| | | | | | | | | | | 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-r12659] This is VMS maintenance check-in.Elena Pourmal2006-09-112-1/+8
| | | | | | | | | | | Some of the tests cannot be run on VMS since they try to open the same file twice. Solution: Bypass the tests according to the H5_CANNOT_OPEN_TWICE variable setting. Platforms tested: VMS server and heping.
* [svn-r12657] Description:Quincey Koziol2006-09-111-1/+0
| | | | | | | | | Clean up whitespace/formatting. Tested on: Mac OS/PPC 10.4 (amazon) Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12655] Description:Quincey Koziol2006-09-111-0/+73
| | | | | | | | | | | | 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 Koziol2006-09-051-21/+51
| | | | | | | | | | | | 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-r12644] Description:Quincey Koziol2006-09-051-346/+380
| | | | | | | | | | | | | 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. Tested: Mac OS X/PPC 10.4 (amazon) Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12640] Frank Baker2006-09-041-0/+16
| | | | | | | | Description: Add per-directory abbreviated copyright notices (abbreviated COPYING files pointing to full notices). Tested: MANIFEST verified; not otherwise tested.
* [svn-r12638] Description:Quincey Koziol2006-09-041-2160/+3632
| | | | | | | | | | | | 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). Tested: FreeBSD/32 4.11 (sleipnir) Linux/64 2.4 (mir) Linux/32 2.4 (heping) Solaris/64 2.9 (shanti)
* [svn-r12632] Description:Elena Pourmal2006-08-271-9/+9
| | | | | | | | | | Thread safe error test fails due to the changes in the error stack. Solution: Updated the expected error stack. Platforms tested: heping (too minor, probably will fail on Tuesday anyway)
* [svn-r12631] Description:Quincey Koziol2006-08-261-1/+1
| | | | | | | | | | | | | | | | | Refactor the file storage of "twig" nodes in the B-tree to allow them to store more records, increasing the average density of the B-tree 30-40%. Increase # of records in "insert lots" regression test to still create B-tree of depth 4 Update h5debug to interpret difference of 'branch' and 'twig' internal nodes in B-tree correctly. Tested on: FreeBSD/32 4.11 (sleipnir) Linux/32 2.4 (heping) Linux/64 2.4 (mir) Solaris/64 2.9 (shanti)
* [svn-r12630] Description:Quincey Koziol2006-08-262-3/+3
| | | | | | | | | | | Re-order the fheap & btree2 tests so that the btree2 test runs first, because the fractal heaps use v2 B-trees for tracking huge objects. Tested on: FreeBSD/32 4.11 (sleipnir) Linux/32 2.4 (heping) Linux/64 2.4 (mir) Solaris/64 2.9 (shanti)
* [svn-r12627] Skipped links and fheap tests when stdio file driver is used.James Laird2006-08-242-2/+3
| | | | | | | | | These errors should be investigated more thoroughly later. The underlying problem in links.c seems to be that files opened multiple times don't share the same H5F_shared_t struct. Perhaps identifying when this is the case would be helpful? Tested on mir.
* [svn-r12623] Added H5Fget_intent() function to get the "intent" of a file ↵James Laird2006-08-242-3/+47
| | | | | | | | | (read/write or read-only). Added this to external links, so that external files are opened with the same intent as the source file. Added tests.
* [svn-r12620] Description:Quincey Koziol2006-08-231-5/+5
| | | | | | | | | Clean up some compiler warnings by removing "UNUSED" from function prototypes. Tested on: Linux 2.? (tg-login3) Too minor to require h5committest
* [svn-r12611] Description:Quincey Koziol2006-08-221-2/+3
| | | | | | | | Remove unused flag byte from fractal heap metadata on disk. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12610] Description:Quincey Koziol2006-08-221-8/+12
| | | | | | | | | | | | | | Add support for checksumming fractal heaps. This is always enabled for the heap header and indirect blocks (as they are "pure" metadata) and is optional for direct blocks, since they may be used for "raw" data. Also, rearrange direct block routines in H5HFcache.c to be in a more sensible location in the file. (probably should have been a separate checkin, since the diffs are mostly useless for this checkin... *sigh*) Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12608] Checked in External Link C examples.James Laird2006-08-221-11/+12
| | | | | | | | Since these examples need to follow filesystem paths, the Makefiles need to create directories in the examples directory; added this to the Makefile.am. Tested on Windows, mir, juniper
* [svn-r12607] Description:Quincey Koziol2006-08-221-5/+5
| | | | | | | | | | | Tweak the library's new faster fletcher32 algorithm to always produce the same checksum as the previous fletcher32 code in the fletcher32 I/O pipeline filter and switch the filter to use the library's version of the algorithm. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2) Too minor to require h5committest
* [svn-r12605] Description:Quincey Koziol2006-08-216-9/+207
| | | | | | | | | | | | | Break out a bunch of the misc. routines that were in src/H5.c into more specific modules. Add optimized fletcher32 checksum routine, for checksumming metadata as well as raw data. Tested On: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2) Will test further after checkin...
* [svn-r12603] Description:Quincey Koziol2006-08-211-171/+570
| | | | | | | | | | | | | | | | | | | Add a bunch more regression tests: - Verify opening a fractal heap more than once works correctly - Check that 0 & 1-sized object insertions are handled correctly - Check that bad heap IDs are detected when attempting to read an object - Check that doubling tables with different parameter values are working correctly Add some more checks to the code to detect 0-sized object insertions and bad heap IDs for reading. Tested On: FreeBSD/32 4.11 (sleipnir) Linux/32 2.4 (heping) Linux/64 2.4 (mir) Solaris/64 2.9 (shanti)
* [svn-r12598] Description:Quincey Koziol2006-08-191-1/+1
| | | | | | | | | | | | | | - Migrate "direct block location" routine from H5HFman.c to H5HFdblock.c, which is a more appropriate location - Optimize performance of heap code by taking advantage of pinned indirect blocks and use them without putting a metadata cache protect/unprotect pair around them. - Other minor compiler warning cleanups and optimizations... Tested On: FreeBSD/32 4.11 (sleipnir) Linux/64 2.4 (mir) Solaris/64 2.9 (shanti)
* [svn-r12596] Refactored how external files are opened and closed.James Laird2006-08-181-10/+300
| | | | | | | | Object header locations (H5O_loc_t's) can now "hold open" a file and decrement its open object count when they close. This means that locations (H5O_loc_t's and H5G_loc_t's) should always be freed. Added more thorough tests to ensure that external files are closed.
* [svn-r12595] Modified H5C_insert_entry() to accept the H5C__PIN_ENTRY_FLAG entryJohn Mainzer2006-08-172-0/+323
| | | | | | | | | | | flag, and pin an entry as it is inserted. The objective is to avoid some function call overhead in fheap. Also added matching test code in test/cache.c & test/cache_common.c (also testpar/t_cache.c checked in separately by accident) h5commit tested
* [svn-r12592] Description:Quincey Koziol2006-08-171-19/+1921
| | | | | | | | | | | | | | | | | | | | | Several changes, all mooshed together: - Add support for "tiny" objects - which can be stored in the heap ID itself, instead of in the heap data blocks. - Flesh out support for compressed direct blocks, but comment it out until John's got some metadata cache changes in place to support it. - Add support for applying I/O pipeline filters to 'huge' objects - Refactor 'huge' object code to store information for 'huge' objects directly in the heap ID, when there are I/O pipeline filters applied to the heap (and the heap ID is large enough to hold the information) - Update h5debug tool to correctly handle 'huge' & 'tiny' objects. - Misc. other code cleanups, etc. Tested on: FreeBSD/32 4.11 (sleipnir) Linux/64 2.4 (mir) Solaris/64 2.9 (shanti)
* [svn-r12584] Mentioned VFD in test output to make it easier to tell which ↵James Laird2006-08-171-7/+6
| | | | | | | | | VFD is being used when a test is run. Running reconfigure also regenerated error header files (because someone edited them manually?).
* [svn-r12575] Description:Quincey Koziol2006-08-141-33/+151
| | | | | | | | | | | | | Allow the heap ID length to be chosen at heap creation time, to allow for making heap IDs long enough to directly embed the file offset & length of 'huge' objects in the heap ID (which allows them to be retrieved directly from disk, instead of requiring them to be looked up in the B-tree that tracks 'huge' objects) Tested on: FreeBSD/32 4.11 (sleipnir) Linux/64 2.4 (mir) Solaris/64 9 (shanti)
* [svn-r12573] Description:Quincey Koziol2006-08-131-154/+1007
| | | | | | | | | | | | Clean up a couple of compiler warnings in the 'huge' object code in the library. Add a bunch of 'huge' object regression tests Tested on: FreeBSD 4.11 (sleipnir) Linux/64 2.4 (mir) Solaris/64 2.9 (shanti)
* [svn-r12565] Description:Quincey Koziol2006-08-111-1/+1
| | | | | | | | | | | | | | Move metadata cache address rename for fractal heap indirect block immediately after reallocing the storage on disk - to prevent another routine in the library from confusing the cache by allocating more storage and attempting to insert it in metadata cache at the old block's location. Gotta like those monte carlo/random insert & delete tests, which exposed this... :-) Tested: Solaris 2.9 (shanti) Not failing on other machines
* [svn-r12562] Description:Quincey Koziol2006-08-101-425/+589
| | | | | | | | | | | | Initial revision to add support for "huge" objects in the heap (which are actually stored directly in the file, but are tracked with v2 B-tree that is accessed through heap header). Testing: FreeBSD 4.11 (sleipnir) Linux/64 2.4 (mir) Linux/32 2.4 (heping) Mac OS X.4 (amazon)
* [svn-r12561] Description:Quincey Koziol2006-08-101-94/+185
| | | | | | | | | | | | Update code formatting a little and refactor to add a better mechanism for performing callbacks when removing records from the B-tree or deleting entire B-tree. Testing: FreeBSD 4.11 (sleipnir) Linux/64 2.4 (mir) Linux/32 2.4 (heping) Mac OS 10.4 (amazon)
* [svn-r12558] Problem:Elena Pourmal2006-08-091-5/+5
| | | | | | | | | | Daily test for ttsafe failed on several machines due to the changed error stack. Solution: Updated the source code to use new error stack. Platforms tested: shanti
* [svn-r12552] Description:Quincey Koziol2006-08-071-115/+46
| | | | | | | | | | | More tweaks on fractal heap statistics, to better separate information about managed objects from information about "huge" objects. Also, clean up some compiler warnings, etc. on 64-bit platforms & Windows. Platforms tested: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago)
* [svn-r12551] Description:Quincey Koziol2006-08-071-10/+8
| | | | | | | | | | | Refactor fields in heap header to clean out information from dropped features and also group related fields together more nicely. Add fields to heap header for storing information about "huge" objects. Platforms tested: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago)
* [svn-r12550] Description:Quincey Koziol2006-08-071-1/+1
| | | | | | | | | | | Refactor fractal heap IDs to include "flag byte" as part of the ID. This byte will be used for the heap ID format version as well as flags to indicate whether the heap object is a "tiny"/normal/"huge" object (with storage mechanisms optimized for each type of object). Platforms tested: Linux/32 2.4 (chicago) Too minor to require h5committest
* [svn-r12549] Description:Quincey Koziol2006-08-071-6512/+1386
| | | | | | | | | | Add support for entire heap deletion. Platforms tested: FreeBSD 4.11 (sleipnir) Linux/32 2.4 (chicago) Linux/64 2.4 (mir) Mac OS X (amazon)
* [svn-r12544] Description:Quincey Koziol2006-08-041-31/+67
| | | | | | | | | | | | | | Clean up compiler warnings/failures in test/links.c, especially when --disable-production flag used with --enable-group-revision Modify binary dumping in h5dump to clean up files created [a band-aid solution to not actually creating the files in the srcdir, but better than just leaving the files around... :-/ ] Tested: FreeBSD 4.11 (sleipnir) (w/ configure flags above) Too minor to require h5committest
* [svn-r12533] Standardized the way path prefixes are passed to external links ↵James Laird2006-08-031-4/+1
| | | | | | using a LAPL. Now there are H5Pget and H5Pset functions for "elink_prefixes".
* [svn-r12530] Skipped objcopy and links tests when certain file drivers are used.James Laird2006-08-032-5/+5

* [svn-r12529] Fixed a couple of bugs that were causing trouble for Windows ↵James Laird2006-08-031-1/+1
| | | | | | builds (not sure why they weren't on other systems). Thanks, Kent!
* [svn-r12528] Added User-Defined links to the library.James Laird2006-08-0217-262/+4682
| | | | | | | | | | | | | | Users can create external links using H5L_create_external(). These links point to an object in another HDF5 file. Users can alter the behavior of external links or create new kinds of links by registering callbacks using the H5L interface. Added tests, tools support, etc. Also a number of other, minor changes have been made (some restructuring of the H5L interface, for instance). Additional documentation and examples are forthcoming.
* [svn-r12524] Changed number of arguments to H5Gcreate_expand. Should stop ↵James Laird2006-08-021-8/+13
| | | | | | the DT from dying again.
* [svn-r12521] Description:Elena Pourmal2006-07-311-11/+11
| | | | | | | | | ttsafe test failed on the tts_error call. The error was due to the outdated expected error stack; fixed. Test was also moved to use new error APIs. Platforms tested: Linux 2.4 (heping) and Solaris 2.9 (shanti)
* [svn-r12519] Fixed "make check-vfd"James Laird2006-07-3123-2655/+2907
| | | | | | | | | | "make check-vfd" will now run all tests in the test directory with different file drivers (at least, all of those tests that use the testing framework's FAPL). Tests that fail will be skipped. This is not a perfect fix, but is better than nothing. Along with this change, check-vfd should be added to the Daily Tests.
* [svn-r12517] Description:Quincey Koziol2006-07-311-3223/+6337
| | | | | | | | | | | | | | | Fix the last scattered bunch of problems with the object deletion code, which appears to be completely working now (for objects that are stored within heap blocks - standalone objects aren't implemented yet). Also, re-work the regression test to speed up some of the existing tests and add in 100-200 more combinations of tests - overall, its probably even slower than it was... :-/ Tested: FreeBSD 4.11 (sleipnir) Linux 2.4 (chicago) Mac OS X (amazon)
* [svn-r12495] Description:Quincey Koziol2006-07-251-7/+7
| | | | | | | | | | Checkpoint further work on object deletion code for fractal heaps. I believe everything is finally working for this sub-task. More regression tests soon, but I don't foresee any problems. Machines: FreeBSD 4.11 (sleipnir) Linux 2.4 (chicago)
* [svn-r12491] Description:Quincey Koziol2006-07-221-149/+441
| | | | | | | | | | Refactored object deletion code for fractal heap to fix scaling problems. Passing all previous tests again now. Tested: FreeBSD 4.11 (sleipnir) Linux 2.4 (chicago) Mac OS X (amazon)
* [svn-r12474] Quincey Koziol2006-07-155-9/+5
| | | | | | | | Clean up some compiler warnings. Tested on: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r12465] Add regression test to check that the library handles files ↵Quincey Koziol2006-07-143-47/+425
| | | | | | | | with merged object header messages properly. Too minor to require h5committest
* [svn-r12462] Committed a variety of metadata cache related changes:John Mainzer2006-07-134-32/+1966
| | | | | | | | | | | | | | | | | | | | | | 1) Added trace file support to the metadata cache. This allows capture of all metadata cache calls in trace files for purposes of optimization and debuging. 2) Added an expunge entry function. This allows an entry to be deleteded from the cache without writing it to disk even if it is dirty. 3) Added a function call to resize pinned entries. 4) Added code to deal with entries that are dirty on load. This is needed in support of a bug fix which can alter object headers on load to repair files. 5) Added progress reporting code to the "MDC API smoke check" test in cache_api.c. To enable the progress reporting, set report_progress to TRUE in mdc_api_call_smoke_check(). Tested with h5committest, and a parallel test on phoenix (dual athelon linux box).
* [svn-r12461] Cleaned up the names of some internal API functions, cleaned up ↵starfire2006-07-102-13/+13
| | | | | | | | | comments, fixed a few tests that used incorrect names for H5L APIs (formerly hidden behind H5_GROUP_REVISION ifdefs Mostly cosmetic changes, tested on mir.
