4537 5455 d 23 h trochtova /branches/dd/ dd branch synchronized with trunk (revision 4536)  
4055 5554 d 20 h trochtova /branches/dd/ changes in trunk (rev 4054) merged into dd branch  
3022 5837 d 22 h decky /branches/dd/ device drivers branch  
2216 6255 d 13 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2111 6316 d 20 h decky /trunk/kernel/generic/src/adt/ fix signed/unsigned comparison  
2089 6324 d 19 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6335 d 12 h jermar /trunk/ (c) versus (C)  
1787 6525 d 14 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1757 6546 d 20 h jermar /kernel/trunk/ Cleanup of comments.  
1708 6550 d 22 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1704 6553 d 1 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6553 d 18 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1483 6565 d 19 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 6600 d 16 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1221 6605 d 10 h decky /kernel/trunk/ printf-related and other code cleanup  
1196 6611 d 20 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1177 6615 d 20 h jermar /kernel/trunk/generic/ Modify B+tree node key width to be 64-bit wide on all platforms.  
1164 6618 d 16 h jermar /kernel/trunk/generic/ Switch B+tree node allocation from malloc() to a dedicated slab - btree_node_slab.  
1150 6624 d 0 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 6624 d 11 h jermar /kernel/trunk/generic/src/ s/B+-tree/B+tree/  
1147 6624 d 11 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 6626 d 14 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 6626 d 22 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 6628 d 14 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 6632 d 14 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 6633 d 17 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 6635 d 12 h jermar /kernel/trunk/ Small textual changes.  
1101 6638 d 12 h jermar /kernel/trunk/ B+-tree implementation.
Currently supports only inserting and searching.
