15:13
Reenable the whereShortCut() optimization. check-in: 97c7b5580f user: dan tags: trunk
14:18
Update test file eval.test to account for caching in the RowDecoder. check-in: 3bbe9e80b8 user: dan tags: trunk
12:12
Fixes to sqlite4FindInIndex so as to handle WHERE clauses of the form "x IN (SELECT a FROM tbl)" where there are usable indexes on both "a" and "x". check-in: 856ed13e06 user: dan tags: trunk
02:52
Update comments on OP_MakeRecord. No changes to code. check-in: 70d85ff051 user: drh tags: trunk
01:12
Fix the RowDecoder caching logic by adding new cache clears to opcodes that move the cursor. check-in: d5abe1bca0 user: drh tags: trunk
00:55
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
20:07
Rename the ValueDecoder object to RowDecoder, in anticipation of enhancing it to be able to extract content from both the key and the value. Simplifications and cleanup of the VdbeCursor object. check-in: 6c7c9133d7 user: drh tags: trunk
19:25
Replace test file distinct.test with the version from sqlite3. This version accounts for NGQP related changes. check-in: 41fc47c1cd user: dan tags: trunk
18:56
Remove routines related to sqlite3 varint format. check-in: a30bf1665b user: dan tags: trunk
18:47
Remove the (non-working) xfer-optimization code. check-in: edd188471c user: drh tags: trunk
18:30
Reenable covering index support in NGQP. check-in: 9e99914519 user: dan tags: trunk
2013-07-23
16:50
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
Add two new value-encoding header codes to represent REAL-IN-KEY and NONREAL-IN-KEY. This is an incompatible file format change. check-in: b7ac369ba7 user: drh tags: trunk
19:49
Fix compiler warnings. check-in: 610033d7f5 user: drh tags: trunk
18:38
Add the COVERING clause to CREATE INDEX statements. Does not work yet, this commit just adds parser support. check-in: 1710627ec6 user: dan tags: trunk
13:24
Disable automatic indices at all times. They do not currently work. Needs to be fixed. check-in: 446fbd37d1 user: drh tags: trunk
12:50
Merge the NGQP branch back into trunk. Currently 12 tests are failing in src4.test (all errors are artifacts of the test code). check-in: 4af30d63ec user: dan tags: trunk
12:28
Changes necessary to get TH4 to compile again. check-in: 15e8dd41a9 user: drh tags: trunk
