15:30
Add decoder logic to facilitate extracting column values from the key of a key/value pair for a row. check-in: 30167422e4 user: drh tags: trunk
2013-07-25
23:26
Add the kvreplace(K,V) pragma for use in testing. check-in: b5ceafc26f user: drh tags: trunk
20:02
Partially reenable automatic indexes. Six legacy tests cases in autoindex1.test are still failing as of this commit. check-in: 2244abfac2 user: dan tags: trunk
15:13
Reenable the whereShortCut() optimization. check-in: 97c7b5580f user: dan tags: trunk

Enhance the RowDecoder object so that it persists on a VdbeCursor and can be reused for multiple OP_Column operations. This opens the possibility of adding caching of header information and/or values in a later check-in. check-in: 6ed358511b user: drh tags: trunk
2013-07-24
21:38
Move all VdbeCursor methods into the vdbecursor.c source file. check-in: 5d08b14478 user: drh tags: trunk

Change where.c to read values from covering indexes instead of tables whenever possible. Modify OP_SeekPk to defer seeks (as OP_Seek does in sqlite3). check-in: 7f6b4708c2 user: dan tags: trunk
2013-07-22
20:12
