* [svn-r13926] Description:Quincey Koziol2007-06-291-43/+73
| | | | | | | | | | | | Add small interface to "wrap" a static buffer (usually on the stack), but still allow for buffers larger than the static buffer to be allocated. This can eliminate _many_ short-lived buffer allocations in situations where the buffer is a predictable size (or at least a "very likely" size). Also, some minor code cleanups, particularly in the SOHM caching code. Tested on: Mac OS X/32 10.4.10 (amazon)
* [svn-r13253] Updated all C and C++ style source code files with the THG ↵Albert Cheng2007-02-071-2/+3
| | | | | | | | | copyright notice. Tested platform: Kagiso only since it is only a comment block change. If it works in one machine, it should work in all, I hope. Still need to check the parallel build on copper.

| | | | | | | | | | | | Move datatype messages into new shared message method interface Clean up various formatting & compiler warnings Minor optimizations Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r13115] Description:Quincey Koziol2007-01-061-0/+2
| | | | | | | | Allow a heap to be marked for deletion while it is still open and being accessed. (Blocks further opens though). Tested on: FreeBSD/32 6.1 (duty)
* [svn-r13016] Description:Quincey Koziol2006-12-041-2/+2
| | | | | | | | | | | Finish moving object header message routines into their own source code module, along with renaming them to have "H5O_msg_" prefix... Tested on: Mac OS X/32 10.4.8 (amazon) FreeBSD/32 4.11 (sleipnir) Linux/32 2.4 (heping) AIX/32 5.? (copper)
* [svn-r13015] Description:Quincey Koziol2006-12-041-3/+3
| | | | | | | | | | | Migrate more object header routines to use the H5O_msg_ prefix and put them into the src/H5Omessage.c code module. Tested on: Mac OS X/32 10.4.8 (amazon) FreeBSD/32 4.11 (sleipnir) Linux/32 2.4 (heping) AIX/32 5.? (copper)
* [svn-r12823] Description:Quincey Koziol2006-10-291-17/+184
| | | | | | | | | | | | | 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
* [svn-r12774] Modified flush code in the metadata cache to allow it toJohn Mainzer2006-10-181-6/+23
| | | | | | | | | | | | | | | | | 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-r12768] Description:Quincey Koziol2006-10-161-6/+6
| | | | | | | | | | 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-r12733] Description:Quincey Koziol2006-10-091-1/+1
| | | | | | | | | | Use calloc() instead of malloc(), in order to fail a bit more gracefully on errors. 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
* [svn-r12702] Description:Quincey Koziol2006-10-021-0/+21
| | | | | | | | | | | | | | | | | 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. Tested on: FreeBSD/32 4.11 (sleipnir) w/threadsafe Linux/64 2.4 (mir) w/1.6 compat Linux/32 2.4 (heping) w/FORTRAN & C++ Mac OSX/32 10.4.8 (amazon)
* [svn-r12700] Alert:Quincey Koziol2006-10-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-r12614] Description:Quincey Koziol2006-08-221-12/+12
| | | | | | | | Various minor reformatting & code cleanups. Tested On: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12612] Description:Quincey Koziol2006-08-221-6/+6
| | | | | | | | | | Provide more abstract internal routine for computing checksums on metadata in a file. This will allow a unified policy on which algorithm to choose and under what criteria (length probably) to be more easily maintained. Tested On: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12611] Description:Quincey Koziol2006-08-221-27/+0
| | | | | | | | 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 Koziol2006-08-221-409/+462
| | | | | | | | | | | | | | 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-r12598] Description:Quincey Koziol2006-08-191-0/+16
| | | | | | | | | | | | | | - 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-r12592] Description:Quincey Koziol2006-08-171-32/+207
| | | | | | | | | | | | | | | | | | | | | 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-r12575] Description:Quincey Koziol2006-08-141-0/+6
| | | | | | | | | | | | | 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-r12562] Description:Quincey Koziol2006-08-101-2/+2
| | | | | | | | | | | | 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-r12552] Description:Quincey Koziol2006-08-071-18/+18
