Issue ID: 9476
Summary: Documentation error for MDB_GET_BOTH_RANGE
Product: LMDB
Version: 0.9.28
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: ---
Component: liblmdb
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
The documentation for MDB_GET_BOTH_RANGE is incorrect.
This operation is documented as 'position at key, nearest data'. It appears to
me that it should instead say 'position at key, first data greater than or
equal to specified data'.
If I call mdb_cursor_get with a valid key and a data smaller than all existing
values, then lmdb returns MDB_SUCCESS and the cursor is positioned at the first
value.
If I call mdb_cursor_get with a valid key and a data larger than all existing
values, then lmdb returns MDB_NOTFOUND and the cursor is not repositioned.
The documentation 'nearest data' makes me expect that if I call mdb_cursor_get
with a valid key and a data larger than all existing values, then lmdb would
return MDB_SUCCESS and the cursor is positioned at the last value.
