|
2007-12-27

|
2007-12-17
| ||
| 16:20 | When SQLITE_MAX_SQL_LENGTH is 0, disable the limit. Make the default 0. Once again build the sqlite3 CLI from individual source files so that it can be built on systems that lack tclsh. Tickets #2845 and #2846. (CVS 4636) check-in: 07aeca3b user: drh tags: trunk | |

| 02:45 | Towards getting ORDER BY to match against the correctin columns. This version only looks at the left-most column in a compound SELECT. That is the correct thing to do, but not what SQLite has historically done. (CVS 4620) check-in: bbddf16a user: drh tags: trunk | |
|
2007-12-12
| ||
| 22:24 | Minor cleanup changes on the OP_StackDepth opcode. Added the sidedelete test for additional testing of ticket #2832. (CVS 4619) check-in: c0689409 user: drh tags: trunk | |

|
2007-12-07
| ||
| 23:47 | Change prefix search from O(N*M) to O(NlogM). The previous code linearly merged the doclists, so as the accumulated list got large, things got slow (the M term, a fucntion of the number of documents in the index). This change does pairwise merges until a single doclist remains. A test search of 't*' against a database of RFC text improves from 1m16s to 4.75s. (CVS 4599) check-in: feef1b15 user: shess tags: trunk | |
| 18:55 | In shared-cache mode, make sure the busy hander invoked is the busy handler associated with the database connection that caused the lock contention in the first place. (CVS 4598) check-in: c9eb6591 user: drh tags: trunk | |

| ||
| 17:41 | Fix a leaking database connection in the vacuum2 test script. Ticket #2827. (CVS 4596) check-in: f29deb5f user: drh tags: trunk | |
| 13:26 | Use the specified buffer length, not the maximum buffer length in unixFullPathname() and related functions. (CVS 4595) check-in: f015a387 user: drh tags: trunk | |
