* [svn-r23104] Purpose: Add object header flush dependenciesNeil Fortner2012-12-141-24/+21
| | | | | | | | | | | Description: Added flush dependencies between object header chunks. Also added a new object header proxy object, which is a child dependency of all object header chunks. All objects which are child dependencies of an object header should set up a flush dependency on the object header proxy, so the dependency applies to all object header chunks. Tested: ummon; jam (fails ph5diff -v, unrelated), koala, ostrich (h5committest)
* [svn-r22600] Description:Quincey Koziol2012-07-251-4/+4
| | | | | | | | Bring r22251:22599 from trunk to revise_chunks branch. Tested on: Mac OSX/64 10.7.4 (amazon) w/gcc 4.7.1, C++ & FORTRAN (Not h5committested yet, as this branch doesn't require it)
* [svn-r22422] Purpose: Add support for SWMR with v2 b-treesNeil Fortner2012-05-301-21/+448
| | | | | | | | | | | | | Description: Adds SWMR support to the v2 b-trees when used as a chunk index. Because each node keeps track of the total number of records reachable through each of its children, nodes must be shadowed every time a descendent record is inserted or removed. This implementation prevents this from happening, however, if the node has already been shadowed since the last time the v2 b-tree header was flushed. Also modified SWMR test to include v2 b-trees. Tested: jam, koala, ostrich (h5committest), durandal Note: There is a preexisting failure in the ph5diff (-v) test
* [svn-r22105] Description:Quincey Koziol2012-03-211-34/+34
| | | | | | | | | | Bring r20557:22085 from trunk to this branch, also fixing some other issues/failures in the branch simultaneously. The h5repack tests are still failing, but Neil will be checking into those, so the branch can be fully functional again. Tested on: Mac OSX/64 10.7.3 (amazon) w/debug
* [svn-r22062] Purpose: Fix bugs in chunk cache's SWMR implementationNeil Fortner2012-03-131-0/+1
| | | | | | | | | | | | | | | | | | | | | Description: Two issues were found with the chunk cache's SWMR implementation: 1. Some places were not properly setting the rdcc field in the index udata struct. Fixed. May eventually need to add an rdcc field to the idx_info struct. 2. While recalculating the indices for chunks in a dataset being resized, it was possible for the chunk cache to attempt to flush a chunk before all the indices were updated, which caused problems when a node split and flush dependencies needed to be updated, because the child nodes could not be found in the chunk cache due to the index being out of date. Modified algorithm in H5D_chunk_update_cache to keep a temporary list of entries that got "bumped", and only evict them after all chunks have updated indices. Also modified H5D_chunk_update_flush_dep and H5D_chunk_update_flush_dep to search this temporary list when looking for the child chunk entry. As a side effect, chunks are now more likely to remain in cache after a call to H5Dset_extent (even without SWMR), so performance should improve slightly.
