| 14:26 | Minor tweak to the SQL grammar to make the parser tables a few bytes smaller. (check-in: cc4810b23e user: drh tags: trunk) | |
| 13:47 | In the lemon-generated parser, store the number of symbols on the RHS of each rule as a negative number and add it to the stack pointer, rather than storing the value as a positive and subtracting it. This makes the parser faster. (check-in: b362f0d8ed user: drh tags: trunk) | |
| 11:56 | In the lemon-generated parser, automatically promote SHIFTREDUCE actions on nonterminal systems to pure REDUCE actions, for a performance enhancement. (check-in: c46d94a8cd user: drh tags: trunk) | |
| 01:21 | Simplify error handling logic in sqlite3_exec() to save about 40 bytes. (check-in: 6480916c72 user: drh tags: trunk) | |

| 16:39 | Fix a virtual table problem that can occur when the vtab is on the RHS of a LEFT JOIN and there is a MATCH constraint in the ON clause, or when the vtab is in a sub-query that is the RHS of a LEFT JOIN and there is a MATCH constraint in the WHERE clause of the sub-query. (check-in: 87b3816633 user: dan tags: trunk) | |

| 18:42 | The ".import" command of the shell, and the csv virtual table extension both ignore a single UTF-8 BOM at the beginning of their input. (check-in: 7c15d762d9 user: drh tags: trunk) | |
| 16:13 | Add the "-unsetnull 1" option to the "sqlite3" command in the TCL interface. (Closed-Leaf check-in: cbe441b231 user: drh tags: unsetnull-option) | |

|
2017-06-19

| 11:44 | Experimental "PRAGMA secure_delete=FAST" pragma. The intent is to overwrite deleted content with zeros without increasing the amount of disk I/O. (Closed-Leaf check-in: f1682f0faf user: drh tags: fast-secure-delete) | |
|
2017-06-17
| ||
| 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 Parked on a branch for historical reference.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) | |

| 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) | |

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: bc1951d699 user: dan tags: ctime-refactor) | |

| 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) | |

|
2017-06-11
| ||
| 20:17 | Fix an off-by-one error that messes up the display of loop codes in the ".wheretrace" debugging output for queries with more than 62 candidate loops when SQLITE_ENABLE_WHERETRACE is on. (check-in: 0bbdaf2801 user: drh tags: trunk) | |

| 02:27 | Adjust the implementation of the ".selftest" feature of the shell to avoid using the deprecated sqlite3_get_table() interface. (check-in: 3168e2c92a user: drh tags: trunk) | |
|
2017-06-08
| ||
| 16:23 | Update the recent auto-vacuum fix so that it works for the in-memory pointer-map structure used by this branch. (check-in: 8e311a6dba user: dan tags: begin-concurrent) | |

| 15:55 | Add too/tserver.c - the implementation of a simple multi-threaded server designed for interactive testing of concurrency between connections used by different threads of the same process. (check-in: 05b4fc4340 user: dan tags: server-edition) | |
| 10:55 | Cause the ANALYZE command to build sqlite_stat1 table entries for empty tables with the assumption that such tables really contain 10 elements. This gives better query plans for tables that are truely empty, but is likely to cause problems in legacy systems, so the change is kept off trunk. Some TCL tests fail on this check-in due to the new stat1 entries. (Leaf check-in: c81f260c2d user: drh tags: analyze-empty-tables) | |

| 19:31 | Work toward enhancing kvtest to measure write performance. (check-in: fc73e7d2f1 user: drh tags: trunk) | |
| 15:44 | Change the name of the OP_Seek opcode into OP_DeferredSeek for better clarity of function. No functional code changes. (check-in: ab33d299c7 user: drh tags: trunk) | |
