| 17:15 | Eliminate the OP_VRowid opcode. The regular OP_Rowid now work for both regular and virtual tables. (CVS 6537) (check-in: ecbef45011 user: drh tags: trunk) | |
| 15:32 | Change the OP_Rowid opcode so that a deferred OP_Seek is pending, it simply pulls the rowid from the deferred seek target and does not actually move the cursor or do a seek. Other where.c cleanups. (CVS 6536) (check-in: 1c508a9982 user: drh tags: trunk) | |
| 02:15 | Remove the rowhash object from the code. Rowset now fills its role. (CVS 6535) (check-in: e963bed0fe user: drh tags: trunk) | |
| 00:47 | Extend the Rowset object to contain all the capabilities of Rowhash in addition to its legacy capabilities. Use Rowset to replace Rowhash. In addition to requiring less code, This removes the 2^32 result row limitation, uses less memory, and gives better bounds on worst-case performance. The Rowhash implementation has yet to be removed.

| 18:20 | Move RowHashBlock.nUsed to RowHash.nUsed. Fix a typo in a comment in test_async.c. (CVS 6533) (check-in: 799d31d99f user: danielk1977 tags: trunk) | |
| 17:23 | Fix a segfault that followed a malloc failure introduced by (6527). (CVS 6532) (check-in: 08e71b1140 user: danielk1977 tags: trunk) | |
| 17:13 | Adjust the rowhash.test module so that it recovers gracefully in the rare event of a rowid collision. (CVS 6531) (check-in: 72e1680904 user: drh tags: trunk) | |
| 16:15 | Allocate the initial RowHash object using lookaside. (CVS 6530) (check-in: 9b30ab7199 user: drh tags: trunk) | |

| 17:43 | Change the journal_mode pragma so that it always returns the current journal mode, even on a failed attempt to change the journal mode. Allow the journal mode to be changed as long as there is not a pending transaction. Ticket #3811. (CVS 6526) (check-in: 419e320ae5 user: drh tags: trunk) | |
| 13:32 | Add new tests to show that journal_mode=OFF works with locking_mode=EXCLUSIVE as long as the journal_mode is set prior to the first transaction. Ticket #3811. (CVS 6525) (check-in: e62ac26f72 user: drh tags: trunk) | |
| 12:31 | Clarify the documentation to make it clear that sqlite3_interrupt() does not effect new SQL statements that are started after the running statement count reaches zero. Ticket #3815. (CVS 6524) (check-in: 3182e8bf69 user: drh tags: trunk) | |
| 12:07 | Do not use deprecated interfaces internally when compiling with SQLITE_OMIT_DEPRECATED. Ticket #3813. (CVS 6523) (check-in: 7f17956dfb user: drh tags: trunk) | |

| 16:54 | Revise the implementation of sqlite3_initialize() slightly in order to make it more easily testable. The functionality should be unchanged. (CVS 6519) (check-in: bb1a390a3d user: drh tags: trunk) | |

| 11:57 | Add the SQLITE_HAVE_ISNAN compile-time option which, if present, causes SQLite to use the math library isnan() function rather than its own homebrew implementation of isnan(). (CVS 6517) (check-in: 54d23521c3 user: drh tags: trunk) | |
| 11:56 | Check-in (6514) did not completely remove the obsolete test, resulting in a segfault. This check-in finishes the job. Ticket #3802. (CVS 6516) (check-in: c29b37ea36 user: drh tags: trunk) | |
