/tags/
Canonize pre-0.2.0.3 tags: remove inner branches, tags and trunk directories.
The change now should reflect how those releases looked like after checkout.

Tagging release 0.1.1

Add some @file doxygen comments and improve already existing comments.

printf-related and other code cleanup

/kernel/trunk/
Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.

/kernel/trunk/generic/
Modify B+tree node key width to be 64-bit wide on all platforms.
1164
6705 d 3 h
jermar
/kernel/trunk/generic/
Switch B+tree node allocation from malloc() to a dedicated slab - btree_node_slab.
1150
6710 d 10 h
jermar
/kernel/trunk/generic/
Rename btree_node_left_sibling() to btree_leaf_node_left_neighbour()
and btree_node_right_sibling() to btree_leaf_node_right_neighbour()
as the left and right neighbours of a node needn't be its siblings.

6710 d 21 h
jermar
/kernel/trunk/generic/
Deploy B+tree in address space area management.
Change as_remap() to check for conflicts with other address space areas only when the area in question grows.
1144

jermar
/kernel/trunk/
Completed B+-tree support.
Enable btree_remove().
Reorder some static functions and group them together.
Fix order of nodes in the leaf_head list.
1142
6713 d 8 h
jermar
/kernel/trunk/
Update B+-tree code.
The code is there, btree_remove() has not been tested yet.
(Fixes, if any, are to come later today.)
1140
6715 d 1 h
jermar
/kernel/trunk/generic/
Change B+-tree from 2-3-4 tree to 2-3-4-5 tree by adding space for the fourth key.
This should make key removal easier.
1136
6719 d 0 h
jermar
/kernel/trunk/generic/src/adt/
Try to avoid splitting full B+-tree nodes by trying left or right rotation first.
(This improved memory consumption of this algorithm by some 40% - meassured on 101-item set).
1134
6720 d 4 h
jermar
/kernel/trunk/generic/src/adt/
Change B+-tree to:
- store lesser keys in a key's left subtree
- propagate the bigger of medians (if there are two medians) when splitting a node
1121

Small textual changes.

B+-tree implementation.
Currently supports only inserting and searching.
