1968 6409 d 21 h jermar /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.		  
1965 6409 d 22 h jermar /tags/0.2.0.1/ Tagging release 0.2.0.1  
1483 6558 d 5 h jermar /kernel/trunk/generic/src/ Implement recursive function for deallocating the whole B+tree.
Make use of this function in address space management.		  
1248 6593 d 2 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1221 6597 d 21 h decky /kernel/trunk/ printf-related and other code cleanup  
1196 6604 d 6 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1177 6608 d 7 h jermar /kernel/trunk/generic/ Modify B+tree node key width to be 64-bit wide on all platforms.  
1164 6611 d 3 h jermar /kernel/trunk/generic/ Switch B+tree node allocation from malloc() to a dedicated slab - btree_node_slab.  
1150 6616 d 11 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.		  
1148 6616 d 21 h jermar /kernel/trunk/generic/src/ s/B+-tree/B+tree/  
1147 6616 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 6619 d 1 h 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 6619 d 9 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 6621 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 6625 d 1 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 6626 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 6627 d 22 h jermar /kernel/trunk/ Small textual changes.  
1101 6630 d 23 h jermar /kernel/trunk/ B+-tree implementation.
Currently supports only inserting and searching.
