| 16:03 | Query planner tuning: When deciding between two plans with the same cost, bias the selection toward the one that does not use the sorter. (check-in: f0ec36d479 user: drh tags: trunk) | |
| 13:31 | Make sure enough memory is allocated for pathological quoting cases when computing a quoted table name in the command-line shell. (check-in: 0583b84ab4 user: drh tags: trunk) | |
|

| 21:05 | Merge all recent trunk enhancements into the apple-osx branch. (check-in: 53b14a3888 user: drh tags: apple-osx) | |
| 15:47 | When generating individual loops for each ORed term of an OR scan, move any constant WHERE expressions outside of the loop, as is done for top-level loops. (check-in: 712267c9c0 user: dan tags: trunk) | |

| 16:51 | When generating individual loops for each ORed term of an OR scan, move any constant WHERE expressions outside of the loop, as is done for top-level loops. (Closed-Leaf check-in: e4a022be4b user: dan tags: or-optimization) | |
|
2017-06-21
| ||
| 01:36 | Enable pragma virtual tables for the integrity_check, quick_check, and foreign_key_check pragmas. (check-in: 118f7bb33a user: drh tags: trunk) | |

| 19:20 | Ensure that test tool "tserver" finalizes all statements before attempting to close a database handle. (check-in: d8568aacf0 user: dan tags: server-edition) | |
| 18:19 | Rename the azCompileOpt global constant to avoid a harmless compiler warning about a name conflict with a local variable. (check-in: 94e420ecfb user: drh tags: trunk) | |
| 17:43 | Ensure that the query planner knows that any column of a flattened LEFT JOIN can be NULL even if that column is labeled with "NOT NULL". Fix for ticket [892fc34f173e99d8]. (check-in: 483462682d user: dan tags: trunk) | |

| 19:06 | Avoid adding an artifical "LIMIT 1" on scalar subqueries that do not need it. This seems like a pointless optimization as it makes minimal run-time difference but does increase code complexity. Parked on a branch for historical reference. (Leaf check-in: c21628e9c1 user: drh tags: subquery-limit-opt) | |
| 18:49 | Fix a missing comma in the previous check-in. (check-in: f3db02f490 user: drh tags: trunk) | |
| 17:55 | Rework the code in ctime.c a bit to report on more compile time options. And to only output configuration options passed in to SQLite, not the default values of #define symbols set automatically. Also generate the large array in ctime.c using new script tool/mkctime.tcl, instead of entering it manually. (check-in: 9a443397a6 user: dan tags: trunk) | |
| 17:29 | Ensure that the value of the THREADSAFE symbol is always included when reporting compile time options, even if it was not explicitly configured. (Closed-Leaf check-in: 95141c6426 user: dan tags: ctime-refactor) | |
| 16:39 | Add extra test cases for sqlite3changeset_apply() and ALTER TABLE ADD COLUMN. (check-in: 603838fc9a user: dan tags: trunk) | |
| 09:59 | Version 3.18.2 (check-in: 036ebf729e user: drh tags: release, branch-3.18, version-3.18.2) | |
| 00:39 | When building an ephemeral table of integers, do not assume that the table does not already contain N if the insert cursor points to N-1. Fix for ticket [61fe9745]. Also increase the version number to 3.18.2. This is the release candidate. (check-in: e1b7102908 user: drh tags: branch-3.18) | |

| 18:31 | Minor refactoring change to clarify how ATTACH works. No functional changes. (check-in: 3944a32e1d user: drh tags: trunk) | |
| 13:43 | Prevent pagesize changes on VACUUM in encrypted databases even when running the VACUUM on an attached database. (check-in: 1169384934 user: drh tags: trunk) | |
| 13:41 | Version 3.18.1 (check-in: 77bb46233d user: drh tags: release, branch-3.18, version-3.18.1) | |
| 12:15 | An unintentional fork was created due to a typo when creating branch-3.18. This check-in resolves the fork and is the 3.18.1 release candidate. (check-in: 20e5ffb1ce user: drh tags: branch-3.18) | |

| 16:56 | Move the "shell_add_schema()" SQL function used by the ".schema" command of the command-line shell to a different spot in the shell.c source file so that it is not in the middle of an unrelated module. (check-in: 254617a1cc user: drh tags: trunk) | |
| 16:45 | Fix typo and improve the wording of the description of "Metadata" in the output of the sqlite3_analyzer tool. (check-in: ca1ff70780 user: drh tags: trunk) | |
| 15:06 | Merge the latest changes from trunk. (check-in: 60105c2253 user: drh tags: lsm-vtab) | |
| 13:07 | Fix harmless compiler warnings in the shell.c file (check-in: 9afd7a2ffd user: drh tags: trunk) | |
| 12:50 | Improvements to the ".tables" command in the command-line shell so that it shows the name of all schemas if the name is anything other than "main". (check-in: c7f778b7ce user: drh tags: trunk) | |
| 12:21 | In the command-line shell, enhance the ".schema" command show that it shows the schema for ATTACH-ed databases in addition to "main". (check-in: 48e086284a user: drh tags: trunk) | |
| 07:47 | Increase the version number to 3.18.1. (check-in: 4be2eba8c1 user: drh tags: branch-3.18) | |
| 00:52 | Enhance the sqlite3_analyzer.exe utility so that it computes and shows the number of bytes of metadata on btree pages and per table and index entry. (check-in: 43ad41efa9 user: drh tags: trunk) | |
