254e5c5d11 radix-tree: squash a pointer arithmetic warning 2018-06-21 17:41:56 +01:00

72e2e92f4c radix-tree: fix bug when erasing elts in remove_prefix 
_erase_elt() now zeroes the last element of the array (ie. sets to
UNSET).  Previously remove() was doing this, but not remove_prefix().

40c1f7889f radix-tree: More debugging of remove 
There's now a pretty printer called radix_tree_dump()

n4, n16, and n48 weren't UNSETting the last entry after
sliding values down.

20b9746c5d radix-tree: FIx various bugs to do with removal 
Add radix_tree_is_well_formed() which does some sanity checking
of the tree.

Call the above a lot in the unit tests.

Fix revealed bugs.

06c789eda1 radix-tree: fix some bugs in remove_prefix and iterate 
These weren't working if the prefix key was part of a prefix_chain.

033df741e2 data-struct/radix-tree: pass the value dtr into create. 
Rather than having to pass it into every method that removes items.

576dd1fc41 radix-tree: First drop of radix tree. 
An implementation of an adaptive radix tree.  Has the following nice
properties:

  - At least as fast as the hash table
  - Uses less memory
  - You don't need to give an expected size when you create
  - It scales nicely (ie. no large reallocations like the hash table).
  - You can iterate the keys in lexicographical order.

Only insert and lookup are implemented so far.  Plus there's a lot
more performance to come.
