| 19:03 | Fix an obsolete statement about Lemon in the README.md file. check-in: 4f6ce7a3 user: drh tags: trunk | |
| 18:57 | Cleanup header usage in lsmtest for files that require _O_BINARY. check-in: f3a6a64e user: mistachkin tags: trunk | |
| 18:52 | Updates to the repository README.md file. check-in: 7bfd3ab7 user: drh tags: trunk | |
| 18:33 | In LSM, avoid calling the VFS xTestLock method to test for a lock that conflicts with one held by the same process. The results of such a call are considered undefined (since they are different under win32 and posix). check-in: a82a9bea user: dan tags: trunk | |
| 18:04 | Add the "--newlines" option to the ".dump" command in the shell to disable the newline escaping mechanism. check-in: bde431b1 user: drh tags: trunk | |
| 17:00 | When multiple constraints need to be evaluated for a row, do any constraints that involve correlated subqueries last. Hence, the priority is index-covered constraints first, correlated subquery constraints last, and all others in the middle. This is a follow-on and improvement to the push-down optimization of check-in [d7bb79ed]. check-in: c4cb9048 user: drh tags: trunk | |
| 16:38 | Additional debugging Noop-comment in the constraint generator when wheretrace is enabled. Closed-Leaf check-in: 0ca7474f user: drh tags: defer-where-subqueries | |

| 14:33 | When testing non-indexed WHERE constraints, test those that involve correlated sub-queries last of all. This increases the chances of not having to run the sub-query at all. check-in: 1f9c1f35 user: dan tags: defer-where-subqueries | |
| 13:24 | For sqlite3TreeView() debugging output, show the Expr.flags field on scalar subqueries. check-in: dc857a96 user: drh tags: trunk | |
| 12:07 | Update error message text for standard error codes to better describe the latest usage of those error codes. Modify sqlite3_open_v2() so that it does return a valid sqlite3 object in the event of SQLITE_MISUSE due to bad open flags, so that sqlite3_errmsg() does not report "out of memory" in that case. check-in: f27b6370 user: drh tags: trunk | |

| 20:35 | Adjust copy_file() lsmtest function so it works properly for locked database files on Win32. check-in: 54a38555 user: mistachkin tags: trunk | |
| 20:06 | Add the "PRAGMA secure_delete=FAST" option, which overwrites most deleted content without increasing the amount of I/O. Deleted content might persist on the free page list, however. And extra CPU cycles are used for zeroing, of course. check-in: 38978ce6 user: drh tags: trunk | |
| 19:43 | Change the error message text for SQLITE_ERROR to omit the part about "missing database" as that meaning is now obsolete (since approx SQLite 2.0). check-in: 732f90d6 user: drh tags: trunk | |

| 17:57 | Fix the usleep() macro in the Win32 test code for lsm1. check-in: 63599fa5 user: mistachkin tags: trunk | |
| 17:43 | Add new PRAGMAs: "function_list", "module_list", and "pragma_list". All are enclosed within #ifdef SQLITE_INTROSPECTION_PRAGMAS. The compile-time option is not on ctime.c yet, since these are still experimental and one can always test "PRAGMA pragma_list" and see whether or not it returns an empty set. check-in: e0b6ae92 user: drh tags: trunk | |
| 17:33 | Add the "Pragma_list" pragma. Put all three pragmas created on this branch inside of #ifdef SQLITE_INTROSPECTION_PRAGMAS. Closed-Leaf check-in: 2f3c3781 user: drh tags: list-pragmas | |
| 16:46 | Improve clarity in the Win32 VFS for lsm1. check-in: 9c7a9e80 user: mistachkin tags: trunk | |

| 16:27 | Remove a block from the Win32 VFS for lsm1 that is now superfluous. check-in: 5f726f28 user: dan tags: trunk | |
| 16:09 | In lsmtest, use an empty string instead of ":memory:" when requesting a temporary database from SQLite. This prevents other test code from trying to unlink() ":memory:", which fails on win32. check-in: 281ad505 user: dan tags: trunk | |

| 13:51 | More compact implementation of the typeof() SQL function. check-in: efb4aab0 user: drh tags: trunk | |

| 11:44 | Avoid constantly freeing and reallocing small internal buffers associated with LSM cursors. Instead, allow them to persist for the lifetime of the cursor if they are LSM_SEGMENTPTR_FREE_THRESHOLD (default 1024) bytes or smaller. This change is based on research by Martijn Blaauw. check-in: bacfe8cb user: dan tags: trunk | |
