| 16:21 | Fix harmless compiler warnings. (check-in: a063f7c426 user: drh tags: trunk) | |

| 21:56 | In the CLI, code the "sqlite_parameters" name directly rather than using a macro, for clarity of presentation for users who are reading the code for the purpose of seeing how the CLI implements parameter binding. (check-in: e775ef002d user: drh tags: trunk) | |
| 21:55 | Remove a test from the index build logic which is no longer needed and is in fact unreachable. (check-in: 9b20ee10ff user: drh tags: trunk) | |
| 21:35 | Change the name of the parameter table in the CLI to "sqlite_parameters".

(check-in: 24ef384469 user: drh tags: trunk) | |
| 19:50 | Earlier detection of corruption while added to the freelist. (check-in: 8c80b004ca user: drh tags: trunk) | |

| 15:09 | Improvements to the help text in the CLI. (check-in: 919fec91da user: drh tags: trunk) | |

| 14:24 | For the ".archive --update" command in the CLI, only update files if their mtime or mode has changed. To force an update, use the new --insert instead. (check-in: 191a023ae7 user: drh tags: trunk) | |
|
2019-03-23
| ||
| 00:38 | Support Tcl libraries with a suffix. (Closed-Leaf check-in: 8d0153996a user: mistachkin tags: msvcTcl) | |

| 13:53 | We learn that readdir_r() is deprecated in favor of plain old readdir(), which is now suppose to be threadsafe using thread-local storage. So remove the use of readdir_r() from the test code. (SQLite itself never calls readdir() or readdir_r()). (check-in: 7a0a26ed38 user: drh tags: trunk) | |
| 11:38 | Add the --limit N option to dbfuzz2. Set the default callback limit to 250K. (check-in: b99f8512c0 user: drh tags: trunk) | |
| 01:26 | Sync up the autoconf makefile for MSVC. (check-in: ecbae90aef user: mistachkin tags: msvcTcl) | |
| 01:25 | Support building the Tcl bindings DLL using MSVC. (check-in: 908c4c891f user: mistachkin tags: msvcTcl) | |

| 13:51 | Remove assert() statements based on the counter-factual proposition that 0 is not a valid cursor number. (check-in: c7b336181a user: dan tags: window-functions) | |
|
2019-03-20
| ||
| 20:27 | Experimental change to apply affinity before running CHECK constraints on an INSERT. Note that in the CHECK constraints, REAL affinity really is REAL affinity, and not numeric affinity. This causes failures in some tests that are assuming affinity is applied after CHECK constraints. (Leaf check-in: 9ef69d1839 user: drh tags: apply-affinity-first) | |
| 20:02 | Use the IsReuseSchema() macro more consistently. Also, rename it to IsSharedSchema(). (check-in: c1be211c02 user: dan tags: reuse-schema) | |

| 11:16 | Enhance the rtreenode() function of rtree (used for testing) so that it uses the newer sqlite3_str object for better performance and improved error reporting. Test cases added to TH3. (check-in: 90acdbfce9 user: drh tags: trunk) | |
| 05:45 | Fix various harmless compiler warnings seen with MSVC. (Closed-Leaf check-in: 1c0fe5b576 user: mistachkin tags: noWarnings) | |

| 16:49 | Add missing VdbeCoverage() macros to new code in window.c. (check-in: 4f9b93e6cf user: dan tags: window-functions) | |
| 15:36 | When computing the amount of scratch memory needed during a rebalance operation, assume the worst case for the number of cells per page, rather than relying on the BtPage.nCell value, which might be incorrect for a corrupt database. (check-in: a420ebd08f user: drh tags: trunk) | |
| 11:56 | Revert the OP_MustBeInt opcode implementation on this branch so that it again matches trunk. The extra functionality is no longer required. (check-in: c02f77b1b4 user: dan tags: window-functions) | |
| 11:35 | Tweak the tool/cg_anno.tcl script so that it can run on systems without /usr/bin/tclsh. (check-in: a026189aa4 user: dan tags: trunk) | |
| 11:17 | Update this branch with latest trunk changes. (check-in: 98cc265987 user: dan tags: window-functions) | |
