* [svn-r23095] Purpose: Refactor flush dependency code, add support for ↵Neil Fortner2012-12-121-9/+3
| | | | | | | | | | | | | | | multiple parents Description: Reworked how flush dependencies worked internally, allowing multiple flush dependency parents, and removing the notion of flush dependency heights, instead keeping track of the number of dirty descendents to determine if parents can be flushed. Also removed the requirement that cache clients destroy flush dependencies before eviction (this is now handled by the cache) and removed the maximum number of passes (the cache should detect infinite loops elsewhere). Added test cases for this. Tested: durandal
* [svn-r22887] Purpose:Dana Robinson2012-10-121-8/+8
| | | | | | | | Fixes a variety of compile warnings and issues in the B-tree and heap code. Tested on: jam
* [svn-r22885] Purpose:Dana Robinson2012-10-111-31/+32
| | | | | | | | Adds some additional flush dependency plumbing and fixes some minor issues with the v2 B-tree code. Tested on: local Ubuntu VM
* [svn-r22761] Purpose: Fix testswmr failuresNeil Fortner2012-09-131-10/+66
| | | | | | | | | | Description: Patched H5B2 shadowed list implementation to remove nodes from the shadowed list when they are evicted, and added some missing initializations. Also removed inadvertent temporary changes to the tests that disabled srandom, added assertions and fixed formatting. Tested: ummon
* [svn-r22422] Purpose: Add support for SWMR with v2 b-treesNeil Fortner2012-05-301-4/+191
| | | | | | | | | | | | | 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

| | | | | | | | | | 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
