1 Implementation of SmiHashFile using the Berkeley-DB
|
|
|
|
April 2002 Ulrich Telle
|
|
|
|
September 2002 Ulrich Telle, fixed flag (DB\_DIRTY\_READ) in Berkeley DB calls for system catalog files
|
|
|
|
April 2003 Ulrich Telle, implemented temporary SmiFiles
|
|
|
|
May 2008, Victor Almeida created the two sons of the ~SmiKeyedFile~ class, namely ~SmiBtreeFile~ and
|
|
~SmiHashFile~, for B-Tree and hash access methods, respectively.
