23:26

Run progress callback checks less frequently in the main VDBE evaluation loop. This makes up for the extra CPU cycles used to increment the cycle counter for SQLITE_STMTSTATUS_VM_STEP. check-in: 3e8b0201 user: drh tags: trunk
2013-07-09
15:56

Fixes for test cases running in the "mmap" permutation. check-in: cdb97d41 user: dan tags: trunk
17:57
Drop any existing mapping of the database file when exiting the pager "error state", as it may at this point be too large for the database file. Do not invoke file-control MMAP_SIZE if the database file handle does not support xFetch and xUnfetch (on the grounds that xUnfetch(0) calls to invalidate the mapping cannot be made). check-in: 0ae7e75b user: dan tags: trunk

19:16
Fix two test script problems revealed by permutations.test. check-in: 60cf7e44 user: dan tags: trunk

2013-06-29
15:40

2013-06-28
23:55

19:41
Allow read transactions to be freely opened and closed by SQL statements run from within the implementation of user-functions if the user-function is called by a SELECT statement that does not access any database tables (e.g. "SELECT user_function();"). check-in: f308c485 user: dan tags: trunk

19:12
Fix an error in e_expr.test. check-in: fd4ece18 user: dan tags: trunk
17:40
Make sure that sqlite3_stmt_readonly reports false for PRAGMA journal_mode and PRAGMA wal_checkpoint. Ticket [a589ec069e3]. Also keep track of whether a prepared statement does no reading or writing. check-in: 1937fd8e user: drh tags: trunk
14:24
Add a test to ensure that if BEGIN IMMEDIATE fails with SQLITE_BUSY, it does not leave the user with an open read transaction (unless one was already open). check-in: 22bced36 user: dan tags: trunk
14:07
If the filename argument to the ".import" command in the command-line shell begins with '|' then treat it as an input pipe rather than a file. check-in: 4c02b344 user: drh tags: trunk

11:46
Add extended error code SQLITE_BUSY_SNAPSHOT - returned in WAL mode when a read-transaction cannot be upgraded to a write-transaction because it is reading from a snapshot other than the most recently committed. check-in: 361c2296 user: dan tags: trunk
2013-06-26
22:46
Update the ".import" command of the command-line shell so that it can accept field values that span multiple lines and so that it issues error messages if the input text does not strictly conform to RFC4180. check-in: 93f63215 user: drh tags: trunk
18:04
Add the "vtshim" extension, implementing a wrapper around the virtual table interface to make it Disposable for the CLR. No changes to the core. check-in: 6c3839ef user: drh tags: trunk
16:30
Update the boundary3.tcl script so that it can be run with tcl 8.5 or 8.6 to regenerate boundary3.test. check-in: ebac5afa user: dan tags: trunk
13:22
Add the SQLITE_STMTSTATUS_VM_STEPS option for sqlite3_stmt_status(). check-in: bd4267f1 user: drh tags: trunk

02:05
Attempt to disable inner loops of a join that do not generate output. This does not work, since the inner loops might run zero times and thus inhibit all output. Needs to be enhanced to work only for LEFT JOINs or when we know that the inner loop will always run at least once. check-in: ca839723 user: drh tags: omit-join-table-opt
00:35
Modify the query planner interface so that it always passes in the result set. This is the first step toward adding an optimization that will omit tables from a join that do not contribute to the result. check-in: 2c2577e6 user: drh tags: omit-join-table-opt

2013-06-13
17:58
An index might be useful for ORDER BY if any indexed column is in the ORDER BY clause, not just the first indexed column. check-in: ade473b5 user: drh tags: nextgen-query-plan-exp
17:28
Make sure that disabling the covering index scan optimization does not prevent a covering index from being used to satisfy an ORDER BY clause. check-in: e8b7ea82 user: drh tags: nextgen-query-plan-exp
15:50
Restore the ability to do a BETWEEN query on the rowid. Also fix a nearby comment. check-in: 459a7b90 user: drh tags: nextgen-query-plan-exp
