| 09:59 | Modify an assert() within sqlite3PagerWalFramesize(), a function only ever used by zipvfs, to account for recent zipvfs changes. (check-in: 3bd7c1b2fa user: dan tags: trunk) | |
| 02:20 | Fix harmless warnings on 32-bit MSVC builds. (check-in: 5192f964b2 user: drh tags: trunk) | |
| 01:50 | Make sure of the strchrnul() library function on platforms where it is available. (check-in: ef1aa10b7f user: drh tags: trunk) | |
| 01:29 | Merge micro-optimizations into trunk after fixing the build on MSVC. Performance now shows 7.58% faster than the 3.8.6 release on x64 with gcc 4.8.1 and -Os. (check-in: 1de558bcb1 user: drh tags: trunk) | |
| 01:21 | Fix compiler warnings and change the nullMem structure initializer into a format that MSVC can understand. (Closed-Leaf check-in: 163bfae858 user: drh tags: micro-optimizations) | |

| 14:55 | Remove an unused parameter from sqlite3VdbeIdxRowid(). This is cosmetic only as the C-compiler optimizers were already omitting this parameter on amalgamation builds. (check-in: a10a6bba49 user: drh tags: micro-optimizations) | |

| 14:59 | Remove the EXPENSIVE_ASSERTS in pcache.c having to do with the pSynced field of the Pcache object, as they are incorrect, as revealed by recent pcache enhancements. (check-in: 69a6456077 user: drh tags: trunk) | |

| 14:46 | Do not flatten aggregate subqueries that contain min() or max() functions so that if the min()/max() are discarded by the outer query, they still function and cause non-aggregate expression to be evaluated on the minimal or maximal row. (check-in: 0bdf1a086b user: drh tags: trunk) | |
| 12:18 | Have the sqlite3_index_writer() VMs check that the final values of records inserted into indexes on rowid tables are integers. (check-in: cca376bff3 user: dan tags: ota-update) | |
| 11:14 | Adjust comments to show that subquery flattening restriction (10) was removed from the code back in 2005. This is a comment change only. (check-in: 4ff0eb96bc user: drh tags: trunk) | |

| 18:44 | Add new APIs that take 64-bit length parameters: sqlite3_malloc64(), sqlite3_realloc64(), sqlite3_bind_blob64(), sqlite3_bind_text64(), sqlite3_result_blob64(), and sqlite3_result_text64(). Add the sqlite3_msize() interface. Internal memory allocation routines now use 64-bit unsigned length parameters for safety. Fix the sqlite3_get_table() to use sqlite3_realloc64() to avoid a integer overflow problem. (check-in: 7e4978c003 user: drh tags: trunk) | |
| 17:27 | Add the SQLITE_USER_AUTHENTICATION extension to the trunk. This extension is disabled by default. Special compilation procedures are need to enable it. (check-in: 65884d4f81 user: drh tags: trunk) | |
| 17:14 | Clean up some #includes in the extension API implementation. (Closed-Leaf check-in: b149ef5c63 user: drh tags: user-auth) | |

| 14:01 | Move user authentication blocking from sqlite3_prepare() over to the table lock generator, thus allowing SQL statements (like "PRAGMA locking_mode") that do not touch database content to run prior to authentication. (check-in: 70121e7cf8 user: drh tags: user-auth) | |
| 13:44 | Add support for the extra parameter on the sqlite3_set_authorizer() callback and support for failing an ATTACH with an authentication-required database using bad credentials. The extension is now feature complete, but much testing and bug-fixing remains. (check-in: 596e728b0e user: drh tags: user-auth) | |
| 00:27 | Reorder parameters on the sqlite3_user_*() interfaces for consistency. Add the first TCL test cases. (check-in: 2f6d8f32ee user: drh tags: user-auth) | |

Internal memory allocation routines also now use 64-bit unsigned length parameters for safety. Also add the sqlite3_msize() interface.

By examining this variable in the debugger after a segfault, one can then set a breakpoint on test_memdebug_settitle that will fire just before the problem.

| 18:56 | Fix the compound-select-to-subquery converter so that it works with the new compound-select object linkage introduced as part of the fix for ticket [31a19d11b97088296]. (check-in: 572d4be4db user: drh tags: trunk) | |
| 16:13 | Modify the command-line shell to print a warning when using an in-memory database. (check-in: 90e9deae4a user: drh tags: memdb-warning) | |

| 23:59 | Add a compound-query test to the speedtest1 test program. (check-in: 5329957591 user: drh tags: trunk) | |
| 18:02 | Use the WITH clause to help resolve names for SELECT statements on the left of a compound query. Proposed fix for ticket [31a19d11b97088296a]. (check-in: 67bfd59d90 user: drh tags: trunk) | |
| 00:52 | Add the Mandelbrot Set testcase to the "cte" testset of speedtest1. (check-in: 56febbeb57 user: drh tags: trunk) | |
| 00:18 | Add a new "testset" to the speedtest1 program: The sudoku solver. (check-in: 4677ef2f8a user: drh tags: trunk) | |

| 23:20 | Do away with the "multi-register pseudo-table" abstration. Instead, just use an OP_SCopy to load results directory from the result registers of the co-routine. (check-in: 1e64dd782a user: drh tags: trunk) | |
| 19:12 | Change the OP_Found opcode so that it expands zero-blobs prior to comparing them. Fix for ticket [fccbde530a6583b] (check-in: e2303d1b0c user: drh tags: trunk) | |
| 13:24 | Fix a harmless compiler warning in VS2013. (check-in: 83116ee3e0 user: drh tags: trunk) | |

| 13:12 | Tweaks to the generated VDBE code to make it a little easier to follow. (check-in: 129217ee91 user: drh tags: trunk) | |
| 04:24 | Enable constant expression factoring even if no tables are read and no transaction is started. (check-in: a45b87713c user: drh tags: trunk) | |
| 01:40 | Change the OP_Trace opcode to OP_Init and give it the ability to jump to the initialization code at the bottom of the program, thus avoiding the need for an extra OP_Goto. (check-in: 192dea9731 user: drh tags: trunk) | |

| 22:21 | Add opcodes OP_InitCoroutine and OP_EndCoroutine. Use these to remove the need for separate boolean registers to record when a co-routine has finished. (check-in: 5a88b6a7ae user: drh tags: trunk) | |
| 19:33 | Fix redundant definitions of _LARGE_FILE and _LARGEFILE_SOURCE. (check-in: 4043d87979 user: drh tags: trunk) | |
| 19:26 | In the TCL bindings, make sure Tcl_AppendResult() is always terminated by "(char*)0" and not just "0". (check-in: ea4d23d1c0 user: drh tags: trunk) | |
| 19:18 | Change the OP_InitCoroutine instruction to jump over the co-routine implementation. (Closed-Leaf check-in: a522f364a6 user: drh tags: coroutine-refactor) | |
