3790 5627 d 5 h svoboda /trunk/kernel/ Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.  
3104 5843 d 10 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3058 5846 d 3 h decky /trunk/kernel/generic/src/ proper printf formatting, remove non-standard 'z' modifier  
2504 6155 d 22 h jermar /trunk/kernel/generic/ Give the AVL tree walkers the possibility to take an argument.
Each walker is now supposed to return a bool value to support walk termination.

Switch over from the tasks_btree B+tree to tasks_tree AVL tree.
This makes the fix for ticket #48 complete.
 
2503 6155 d 23 h jermar /trunk/kernel/generic/src/adt/ Get rid of code duplicities in the insert path into an AVL tree.  
2501 6156 d 4 h jermar /trunk/kernel/generic/ Add explicit type for an AVL tree key.
Add function to walk an AVL tree using a supplied walker.
 
2499 6156 d 6 h jermar /trunk/kernel/ Import the AVL tree implementation from the RCU branch.  
2216 6268 d 21 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2112 6330 d 5 h decky /trunk/kernel/generic/src/adt/ explicit typecast, fix signed/unsigned comparison  
2111 6330 d 5 h decky /trunk/kernel/generic/src/adt/ fix signed/unsigned comparison  
2089 6338 d 4 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6348 d 21 h jermar /trunk/ (c) versus (C)  
1787 6538 d 23 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6546 d 0 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6560 d 5 h jermar /kernel/trunk/ Cleanup of comments.  
1708 6564 d 6 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6566 d 6 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.
 
1704 6566 d 9 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6567 d 3 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1549 6577 d 2 h vana /kernel/trunk/generic/src/adt/ Bitmap functions patch  
1483 6579 d 3 h jermar /kernel/trunk/generic/src/ Implement recursive function for deallocating the whole B+tree.
Make use of this function in address space management.
 
1337 6596 d 2 h jermar /kernel/trunk/generic/src/adt/ Remove a misleading comment.  
1262 6610 d 22 h jermar /kernel/trunk/generic/src/adt/ Fix a bug caused by an unsigned subtraction of bigger value from smaller value in bitmap implementation.
Fix wrong calculation of unaligned leading bits in bitmap implementation.
 
1248 6614 d 0 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1221 6618 d 18 h decky /kernel/trunk/ printf-related and other code cleanup  
1200 6624 d 2 h jermar /kernel/trunk/ Add bitmap ADT.  
1196 6625 d 4 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
 
1177 6629 d 5 h jermar /kernel/trunk/generic/ Modify B+tree node key width to be 64-bit wide on all platforms.  
1164 6632 d 1 h jermar /kernel/trunk/generic/ Switch B+tree node allocation from malloc() to a dedicated slab - btree_node_slab.  
1154 6636 d 0 h jermar /kernel/trunk/generic/src/adt/ Fix critical bug in hash table initialization.
Only half of the table was actually allocated and initialized.
 
1150 6637 d 8 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 6637 d 19 h jermar /kernel/trunk/generic/src/ s/B+-tree/B+tree/  
1147 6637 d 19 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 6639 d 23 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 6640 d 6 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 6641 d 23 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 6645 d 22 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 6647 d 1 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 6648 d 20 h jermar /kernel/trunk/ Small textual changes.  
1101 6651 d 21 h jermar /kernel/trunk/ B+-tree implementation.
Currently supports only inserting and searching.
