squashed commits:
create db->get_key_after_bytes() api down to the ft layer, and start a unit test
refs #18
setup/teardown for get_key_after_bytes test
refs #18
rename test because it really is going to be a small unit test
refs #18
implement a few initial checks
refs #18
adding actually_skipped parameter because we will want it in splitVector
refs #18
NULL -> nullptr, I'm rusty from mongo work
refs #18
fix some old apis to fit what get_key_after_bytes needs:
make keyrange_compare_s hold an FT instead of FT_HANDLE to prepare for reuse refs #18
make keyrange_compare_s hold a const dbt refs #18
fix const-correctness of fill_bfe functions refs #18
add unit test for an empty dictionary
refs #18
implement get_key_after_bytes for a single basement node, passes simple tests
refs #18
add test for multiple basement nodes
refs #18
fix usage of ft_search_t, we do need a full one after all
refs #18
check actually_skipped for correctness (even though it's an estimate)
refs #18
restructure test to be faster, and test keys before the beginning of the table
refs #18
don't try to read in the right basement node, just check the bns you have
refs #18
implement get_key_after_bytes for height > 0 trees
refs #18
return the amount skipped even if we hit the end of the table
refs #18
add inexact test for height > 0 trees, adjust constants so it's faster
refs #18
don't do I/O to bring in basement nodes just for get_key_after_bytes
refs #18
don't blindly check the first basement node, it's not guaranteed to be there anymore
refs #18
fix leak in get_key_after_bytes_unit.tdb
refs #18
add get_key_after_bytes to test_stress5
refs #18
switch to a callback API to save mallocs and memcpys
refs #18
We can resurrect this if necessary in the future and we want to support windows.
Right now it just gets in the way and makes checkouts larger."
