| 22:44 | More efficient error handling and reset in the binding mechanism. (check-in: 9a3e3b34ba user: drh tags: trunk) | |
| 19:23 | Instead of a root page number, log the object (table or index) name if a page level locking conflict is detected. (check-in: 9ad846e57b user: dan tags: begin-concurrent) | |
| 17:59 | Omit unnecessary fstat() calls for determining the database file size, resulting in smaller and faster code. (check-in: dd61c73677 user: drh tags: trunk) | |
| 17:43 | Fix an issue with OPT_FEATURE_FLAGS in configure.ac. (check-in: 43ce3bd3a4 user: drh tags: trunk) | |
| 16:45 | Avoid unnecessary fstat() calls to determine the database size when transitioning into a read transaction on a rollback-mode database. (Closed-Leaf check-in: 6c3476b513 user: drh tags: io-opt) | |
| 14:57 | Avoid unnecessary calls to fstat() to determine the database file size. (check-in: c733a1dea3 user: drh tags: io-opt) | |
| 14:30 | Fix a typo in a comment. No code changes. (check-in: cb29b83888 user: drh tags: trunk) | |
| 14:27 | Enhance the log messages emitted when a page conflict is detected. (check-in: 92618492b0 user: dan tags: begin-concurrent) | |
| 14:26 | Optimizations to the Walker object and its methods to make the code a little smaller and to help it run a little faster. (check-in: 6854a34ed7 user: drh tags: trunk) | |
| 13:09 | Correctly initialize the iSelectId of FROM clause terms that are a self join of a reused materialized subquery. Without this, the EXPLAIN QUERY PLAN output for the query will identify the subquery using the uninitialized (and arbitrary) iSelectId. (check-in: 43c9ae371f user: drh tags: trunk) | |
| 03:48 | Improve shell help text for the '.open' command. (check-in: 7cc940a97e user: mistachkin tags: trunk) | |

| 19:04 | Import recent enhancements from trunk. (check-in: 54bec164eb user: drh tags: sessions) | |
| 19:00 | Add extra tests and fixes for multi-column matches. (check-in: ae6794ffa2 user: dan tags: fts5) | |
| 18:42 | Ensure that allocateBtreePage() always clears the MemPage pointer when it fails due to an I/O or memory allocation error. (check-in: 09a38bf665 user: drh tags: trunk) | |
| 17:51 | Move two unreachable conditionals inside of NEVER() or assert(). (check-in: db4e9728fa user: drh tags: trunk) | |
| 17:13 | Remove a corruption test in balance_nonroot that is superceded by a prior better check. (check-in: 00693682d8 user: drh tags: trunk) | |
| 15:55 | Add syntax to fts5 used to specify that a phrase or NEAR group should match a subset of columns. For example "[col1 col2 ...] : <phrase>". (check-in: 0fc0ea2092 user: dan tags: fts5) | |
| 15:15 | Omit the rowallock.test script (Read-Only WAL lock) from the inmemory_journal permutation. (check-in: d21db33089 user: drh tags: trunk) | |
| 14:47 | Add support for automatic indexes on FROM-clause subqueries that are implemented via co-routine. (check-in: 020b8b106f user: drh tags: trunk) | |
| 14:36 | Add some extra source-code comments and a test case. (Closed-Leaf check-in: 6d410442fb user: drh tags: coroutine-autoindex) | |
| 13:55 | An attempt to allow automatic index creation on subqueries accessed via co-routine. (check-in: 521345add6 user: drh tags: coroutine-autoindex) | |
| 01:35 | Using "SELECT ALL" instead of just "SELECT" on a query that uses a single unflattenable subquery or view in its FROM clause will force the subquery to be manifested into a temporary table rather than run incrementally using a co-routine. This is a stop-gap means of controlling the decision to manifest while we try to work out a better to make that decision automatically. (check-in: a29e117d7e user: drh tags: trunk) | |

| 12:36 | Improvements to error messages for errors in the dot-commands of the command-line shell. Add the ".once" command. The output of ".help" now goes to the designated output channel. (check-in: 48dce821a0 user: drh tags: trunk) | |
| 03:17 | Only quote the arguments to the ".shell" and ".system" commands if they contain spaces. (check-in: e58f4bd39d user: drh tags: trunk) | |

| 17:48 | Updates to the Codec interface to support codecs on attached databases and to allow rekeying in the middle of a transaction. These changes are only applicable if SQLite is compiled with SQLITE_HAS_CODEC. (check-in: d5b084e9d8 user: drh tags: trunk) | |
| 14:22 | Add tests for running FTS 'merge' and 'optimize' commands in shared cache mode. (check-in: 09e5a7ad85 user: dan tags: trunk) | |

| 20:22 | Consolidated inline assembly versions of "hwtime()" into hwtime.h. Provided MSVC version. Modified code for consistent use of hwtime(). Changed implementation to use sqlite_uint64 and sqlite_int64 instead of unsigned long long int and long long int for MSVC compiler support. (CVS 5179) (check-in: 19f5f571dd user: shane tags: trunk) | |

| 05:23 | Fix cosmetic issues spotted while working on ticket #3146 (CVS 5177) (check-in: 5f6eab65db user: drh tags: trunk) | |
| 03:54 | Moved check and define for OS_WINCE from os_win.c to os.h (with the other OS_* defines). This allows OS_WINCE to be available for mutex_w32.c which is included earlier than os_win.c in the almagamation. (CVS 5176) (check-in: ad6a782e7c user: shane tags: trunk) | |
| 03:20 | When initializing the sqlite_sequence entry for an AUTOINCREMENT table, make sure the value is an reasonable integer even if the initial insert failed. Ticket #3148. (CVS 5175) (check-in: 7e6847852d user: drh tags: trunk) | |

| 02:57 | Unused functions in testfixture.exe with certain defines. (CVS 5172) (check-in: 5e3ff1bb37 user: shane tags: trunk) | |
| 02:53 | sqlite3OsDl*() APIs can be omitted if SQLITE_OMIT_LOAD_EXTENSION defined. (CVS 5171) (check-in: 7c51a97dc1 user: shane tags: trunk) | |

| 17:50 | Change the row-size limit back to 1MB. It was temporarily raised to 16MB. We'll probably move it to 16MB eventually, but not just yet. (CVS 989) (check-in: b84c4035c6 user: drh tags: trunk) | |
