19:35
When attempting to restart a wal file, make any required calls to sqlite3_randomness() before waiting on or checking for wal file readers. This restores the behaviour exhibited by the trunk. (Closed-Leaf check-in: 6ee08769 user: dan tags: checkpoint-truncate)

2014-11-28
13:35
Remove the ill-designed "-end" option from the command-line shell. Instead, allow multiple SQL or dot-commands as command-line arguments. Any -cmd commands are processed first, followed by other command-line arguments, for backwards compatibility. (check-in: 24fa2e98 user: drh tags: trunk)
11:54
Add the -end option to the command-line shell, which forces it to exit after reading prior command-line options (presumably including one or more -cmd options) and without reading standard input. (check-in: b59397b1 user: drh tags: trunk)
2014-11-27
11:36
Fix a buffer overread during compilation of CREATE VIRTUAL TABLE statements that featured an explicit database name but no virtual table arguments. For example, "CREATE VIRTUAL TABLE main.ft USING fts4". (check-in: f095cde5 user: dan tags: trunk)

12:22
Remove a redundant test case (probably a copy/paste error). Add an assert() to where.c to ensure that automatic indexes do not have there output row counts adjusted downward by supplementary constraints. (check-in: eea47933 user: drh tags: trunk)
2014-11-20
23:21
Fix a typo in a requirements mark on the abs() SQL function. (check-in: b1e6c02f user: drh tags: trunk)

02:58
Fix the encoding of some integers to use the minimum amount of space: -128, -32768, -8388608, -217483648, and -140737488355328. (check-in: 2d7c8da5 user: drh tags: trunk)
02:18
Add some requirements marks to the record formatting logic. Comment changes only - the code is unaltered. (check-in: 9a9627e1 user: drh tags: trunk)

2014-11-18
21:54
Adding the "noskipscan" token to an sqlite_stat1.stat field prevents an index for being used with the skip-scan algorithm. (check-in: 4461bf04 user: drh tags: trunk)
21:45
Allow an automatic index to be used if the only uses of declared indexes for the same loop use the skip-scan algorithm. (check-in: c52f7971 user: drh tags: trunk)
20:49

20:22
Fix a bug in the sqlite3TripAllCursors() routine that prevents it from reporting errors. It is unknown at this time whether or not this omission can result in any incorrect result in an actual query. (check-in: 2896f264 user: drh tags: trunk)
20:16
Update a couple of test cases to account for the fact that ROLLBACK does not always abort all running SELECT statements. (check-in: abccda76 user: drh tags: trunk)

15:32
Fix a bug in the sqlite3TripAllCursors() routine that prevents it from reporting errors. It is unknown at this time whether or not this omission can result in any incorrect result in an actual query. (check-in: 42588207 user: drh tags: branch-3.8.7)

Have calls to sqlite3_backup_init() fail if there is already a read or read-write transaction open on the destination database. (check-in: 169b5505 user: dan tags: trunk)
13:42
When a transaction or savepoint rollback occurs, save the positions of all open read-cursors so that they can be restored following the rollback operation. Cherry-pick of check-in [dd03a2802f3f27] (check-in: 402780a9 user: drh tags: branch-3.8.7)
2014-11-12

12:17
