| 14:32 | Fix crashes that could occur if SQL NULL values were passed to the built-in FTS5 snippet function. Edit: breaks amalgamation builds. (check-in: 6a790b67a0 user: dan tags: trunk) | |
| 14:30 | Add options to speedtest1.c and speed-check.sh for testing performance of floating-point computatations. (check-in: ebfea8728f user: dan tags: trunk) | |

| 13:43 | Fix an assertion fault on a syntax error input caused by check-in [6b2ff26c25bb9da3]. Problem discovered by OSSFuzz. (check-in: 90d6e4f10d user: drh tags: trunk) | |
| 04:15 | Enhance LEMON so that it generates the action table in such a way that no range check is needed on the lookahead table to verify that the next input token is valid. This makes the lookahead table slightly larger (about 120 bytes) but helps the parser to run faster. (check-in: 7eb0198d01 user: drh tags: lemon-improvements) | |
| 00:10 | In the LEMON-generated parser, avoid unnecessary tests for the acceptance state. (check-in: fdbb35c54f user: drh tags: lemon-improvements) | |

| 23:38 | In the LEMON-generated parser, rearrange the meanings of integer action codes so that reduce actions occur last. This means that the most common case (reduce actions) can be recognized with a single comparison operation, thus speeding up the main parser loop, slightly. (check-in: 7bfe7a3602 user: drh tags: lemon-improvements) | |
| 18:56 | Fix a NULL pointer dereference after a syntax error that can occur as a result of check-in [6b2ff26c25bb9da3] yesterday. This problem was discovered by the OSSFuzz. (check-in: d49afb8f98 user: drh tags: trunk) | |
| 17:06 | Improved parser tracing output. (check-in: 25be575054 user: drh tags: lemon-improvements) | |
| 17:01 | Grammar changes: the sclp non-terminal should always be followed by a scanpt. (check-in: 74a0181fc0 user: drh tags: span-refactor) | |
| 14:14 | Improved parser tracing output. (check-in: c4951833c2 user: drh tags: span-refactor) | |
| 00:18 | Remove the ExprSpan object. Instead, keep track of the test of subphrases in the parse using the "scanpt" non-terminal. (check-in: 3eab7bdc44 user: drh tags: span-refactor) | |

| 18:34 | Merge enhancements from trunk. (check-in: 150f07fec1 user: drh tags: sqlar-shell-support) | |
| 14:39 | Simplification to the error handling logic in the extension loader. (check-in: 07c773148d user: drh tags: trunk) | |
| 13:55 | Improve the error message that comes back when sqlite3_load_extension() fails because the named file exists but is not a valid shared library. (check-in: 05fee1a21e user: drh tags: trunk) | |
| 12:33 | Move the generation of output column names earlier in the case of a CREATE TABLE AS. This is a fix for ticket [3b4450072511e62] and a continuation of check-in [ade7ddf1998190b2b63] that fixes cases of ticket [de3403bf5ae5f72ed6] that were missed previously. (check-in: 6b2ff26c25 user: drh tags: trunk) | |
| 11:51 | Add a SELECTTRACE() macro to indicate when column names are assigned to a SELECT statement. This helps with debugging for tickets like [de3403bf5ae5f72e] and [3b4450072511e621]. (check-in: 8f194008c3 user: drh tags: trunk) | |

| 19:53 | In the sqlite3TreeViewExprList() routine, show the "AS" alias name for each expression in the list, if it exists. (check-in: 5efd854fe2 user: drh tags: trunk) | |
| 00:52 | Modify the new sqlite3_vtab_collation() interface so that it takes a pointer to the sqlite3_index_info object passed into xBestIndex rather than an sqlite3 connection pointer, which the xBestIndex method might not have access to. (check-in: 5c1fe66660 user: drh tags: trunk) | |

| 21:41 | Fix SQLITE_DBCONFIG_TRIGGER_EQP so that it works even if SQLITE_DEBUG is not defined. (check-in: afbbfff720 user: drh tags: trunk) | |
| 21:02 | Add the ".eqp trigger" option to the ".eqp" command in the command-line shell. Implemented using the new SQLITE_DBCONFIG_TRIGGER_EQP control. (check-in: 2c51644a12 user: drh tags: trunk) | |
| 18:55 | Add the ".expert" command to the shell tool's ".help" output. (check-in: fc6193af5d user: dan tags: trunk) | |
| 18:23 | Change the name of SQLITE_DBCONFIG_FULL_EQP to be SQLITE_DBCONFIG_TRIGGER_EQP (which we can do without breaking compatibility because the former name has not yet appeared in an official release) and streamline its implementation. (check-in: fffc7685d1 user: drh tags: trunk) | |
| 14:46 | Add the SQLITE_DBCONFIG_MAX preprocessor macro which will always be equal to the largest SQLITE_DECONFIG value. (check-in: 95d4103348 user: drh tags: trunk) | |
| 02:17 | Add the experimental ".expert" command to the sqlite3.exe shell. (check-in: 0821bae7af user: drh tags: trunk) | |

|

| 20:20 | Add an experimental location(X) SQL function that attempt to return the location of the payload within the database for the record that contains column X. location(X) returns NULL if X is not an ordinary table column or if SQLite cannot figure out the location because it is using a covering index. (check-in: 51be955816 user: drh tags: location-function) | |
| 19:36 | Add the sqlite3_vtab_collation() function, which allows an xBestIndex callback to determine the collation sequence that SQLite will use for a comparison. And the SQLITE_DBCONFIG_FULL_EQP configuration option, which enhances the output of "EXPLAIN QUERY PLAN" so that it includes statements run by triggers. And the code for the sqlite3_expert extension and command line application. (check-in: 4c782c9502 user: dan tags: trunk) | |

| 15:28 | Add the experimental "sqlite_expert" extension. Used to find index definitions that might help with specified SQL queries.

| 20:10 | Have sqlite3_expert_analyze() populate the sqlite_stat1 table before running queries through the planner for the second time. (check-in: a157fcfde5 user: dan tags: schemalint) | |
| 13:50 | Use sqlite3_table_column_metadata() instead of a SELECT statement to check for the existence of a %_stat table in fts3. This leads to smaller and easier to test code. (check-in: dc2a48020a user: dan tags: trunk) | |

| 18:02 | Fix a problem in "PRAGMA foreign_key_check" in handling a WITHOUT ROWID child table with an INTEGER PRIMARY KEY parent key. Also, if an FK violation is detected in a WITHOUT ROWID child table, do not try to read and return the rowid. The second column returned by "PRAGMA foreign_key_check" in this case (WITHOUT ROWID child table) is now always set to NULL. (check-in: 690870bd7b user: dan tags: trunk) | |

| 11:53 | In the skip-ahead-distinct optimization, fix a bug in the logic that determines when to invoke the optimization based on sqlite_stat1 statistics. (check-in: 89f9e4363a user: drh tags: trunk) | |

| 17:18 | An initial attempt to optimize VIEWs that occur as the right operand of a LEFT JOIN. This particular check-in does not work correctly because it does not deal with the case of columns in the VIEW that return non-NULL even when all columns in the table of the VIEW are NULL because of the LEFT JOIN.
