Further work on balance_nonroot(). (check-in: 6594f9b4 user: dan tags: defrag-opt)
2014-10-11
20:00
Attempt to further reduce memcpy() in balance_nonroot(). (check-in: fec849dc user: dan tags: defrag-opt)
2014-10-09
19:35
Change the balance_nonroot() routine to reduce the amount of memcpy work that takes place. This is a work in progress. (check-in: 29304499 user: dan tags: defrag-opt)
2014-09-29
18:47
Add the OPFLAG_MULTICOLUMN flag to the OP_Column opcode. Rearrange OP_Column instructions to take advantage of the new flag for a small performance increase (Leaf check-in: 5e5d6e86 user: drh tags: faster-OP_Column)
15:42
Fix the header comment in sqlite3VdbeDeletePriorOpcode(). No changes to code. (check-in: 7fb16268 user: drh tags: trunk)
15:00
Ensure that the OP_Prev opcode verifies that content has not been deleted out from under the cursor. Fix for ticket [209d31e3161b9e9ff]. (check-in: 414f0d6a user: drh tags: trunk)
2014-09-27
05:00
Reduce the amount of memcpy() required by defragmentPage(). (check-in: 3edab995 user: drh tags: defrag-opt)
2014-09-26
18:30
Add an assert() to verify the last-row-id for the database just prior to calling a SQL function. (check-in: d026f0c9 user: mistachkin tags: trunk)
02:41
Fix the "PRAGMA integrity_check" command so that it avoids formatting error message context messages until it actually needs to generate an error message. This avoids much formatting, and hence greatly improves the performance of "PRAGMA integrity_check" in the common case when there are no errors. It also makes the code a little smaller. (check-in: 83913515 user: drh tags: trunk)
01:10
If an SQL function makes a recursive call to do an INSERT into the same database, make sure that the last_insert_rowid() for that INSERT is recorded. (check-in: e93aecc0 user: drh tags: trunk)
2014-09-25
17:42
Minor code reformatting and comment change, to improve clarity. No logic changes. (check-in: baeb72a3 user: drh tags: trunk)
13:17
Simplifications to the SQL function and aggregate calling procedures. (check-in: 3467049a user: drh tags: trunk)
