| 14:46 | Fix a potential crash in fts5 caused by using an auxiliary function on a "special" query like '*id' or '*reads'. (check-in: 9490683ae8 user: dan tags: trunk) | |
| 02:21 | When applying the IN_INDEX_NOOP optimization and the LHS has REAL affinity, also apply REAL affinity to each element of the RHS. Ticket [2841e99d104c6436]. (check-in: 88833a9c28 user: drh tags: trunk) | |
| 01:25 | Fix an obsolete comment that defines the meaning of one of the parameters to the sqlite3FindInIndex() subroutine. No changes to code. (check-in: 0c946f0846 user: drh tags: trunk) | |
| 00:58 | When computing an expression value for an index-on-expression or a CHECK constraint and the expressions uses a REAL table column, but the value of that column is an integer (in other words, when it is using the store-real-as-integer optimization) be sure to promote the value to real before evaluating the expression. Ticket [57af00b6642ecd68]. (check-in: 0658c16e31 user: drh tags: trunk) | |

| 23:56 | When the affinity of a table column is INT or REAL, make the affinity of corresponding index columns NUMERIC. This increases the precision of index lookups for large numbers so that it matches the precision of ordinary comparison operators. Ticket [40812aea1fde9594] (check-in: e0d909c740 user: drh tags: trunk) | |

| 18:02 | Back out the change at [47cd634c98b502d4] which was incorrect. Add a test case so that we don't accidently back out that change again. (check-in: 596ac2a4ea user: drh tags: trunk) | |
| 17:28 | Add further comments to window.c. (check-in: 900464567b user: dan tags: trunk) | |

| 16:14 | Fix a bug in RANGE window functions that use "ORDER BY <expr> DESC NULLS FIRST" as the window-frame ORDER BY clause. (check-in: 39b4cad4a5 user: dan tags: trunk) | |
| 16:00 | The expression "(X IS FALSE) IN (FALSE)" does not imply that X is NOT NULL. Ticket [f8f472cbc77ba9c9] (check-in: dd66134817 user: drh tags: trunk) | |
| 15:11 | The expression "(X IS FALSE) BETWEEN FALSE AND TRUE" does not implie that X is not NULL. Ticket [fba33c8b1df6a915] (check-in: 057fb8b180 user: drh tags: trunk) | |
| 13:07 | The expression "(x IS FALSE) IS FALSE" does not imply that X is not NULL. Ticket [a6408d42b9f44462] (check-in: 45ff2b1f26 user: drh tags: trunk) | |

| 15:50 | Fix another case where SQLite assumes that if "~(? AND FALSE)" is true, "?" must be non-null. (check-in: 616f5663b3 user: dan tags: trunk) | |
| 15:06 | Avoid assuming that for "~ (? AND FALSE)" to be true, "?" must not be NULL, just as we do for "NOT (? AND FALSE)". Fix for ticket [c0390363]. (check-in: 84ae41fd2f user: dan tags: trunk) | |

|
2019-08-28

| 11:49 | Fix an unreachable branch in sqlite3ParserFallback() (Closed-Leaf check-in: e059178b47 user: drh tags: lemon-optimization) | |
| 11:31 | Further improvements to parser speed by enlarging lookup tables to eliminate the need to do range checking on the index prior to lookup. (check-in: 47d3e091ae user: drh tags: lemon-optimization) | |

| 21:11 | Attempt to parse the NULLS LAST clause more efficiently. A few cycles were saved, but at the expense of more code. And there is a bug was introduced somewhere. Not worth continuing down this line. (Closed-Leaf check-in: 12d2cf8871 user: drh tags: dead-end) | |
| 20:33 | Move some things in parse.y so that TK_COLUMN and TK_AGG_COLUMN are assigned the same values as they are on trunk for a very small speedup. (check-in: d26fdfa3bc user: dan tags: nulls-last) | |
| 17:09 | Revise the VDBE comments for NULL-scan so that they also work make sense when reading a NULLS FIRST plan. (check-in: bfe793780f user: drh tags: nulls-last) | |
| 17:00 | Additional simplifications of the WHERE loop code generator logic for NULLS LAST. (check-in: 1383680d92 user: drh tags: nulls-last) | |
| 16:12 | Simplification of the WHERE loop code generator for NULLS LAST saves a few CPU cycles and about a hundred bytes of code space. (check-in: e3ed2f496f user: drh tags: nulls-last) | |
| 13:32 | Invert the meaning of the regBignull flag so that it is 1 when doing the normal scan and 1 when scanning nulls. This enables the re-do jump at the bottom of the loop to be coded with a single OP_IfNotZero opcode, rather than a sequence of OP_If, OP_Integer, OP_Goto. (check-in: bf875e1a25 user: drh tags: nulls-last) | |
| 13:08 | Extra VDBE comments in the NULLS LAST logic provide landmarks to help understand the EXPLAIN output. (check-in: 649b08ead5 user: drh tags: nulls-last) | |
|

| 15:47 | Merge trunk changes into this branch. (check-in: db1e60800b user: dan tags: nulls-last) | |
| 00:53 | The SQLITE_DIRECTONLY flag, when added to sqlite3_create_function() prevents the function from being used inside a trigger or view. (check-in: de76737698 user: drh tags: trunk) | |
|
2019-08-16
| ||
| 22:58 | Add the ability to unregister a virtual table module by invoking sqlite3_create_module() with a NULL sqlite3_module pointer. (check-in: 31e34fa339 user: drh tags: trunk) | |
| 21:07 | Add support for using indexes for some ORDER BY clauses that use non-default NULL handling. Still some problems on this branch. (check-in: 81069d7196 user: dan tags: nulls-last) | |

| 23:11 | Fix harmless compiler warnings in the TCL interface. (check-in: f17e72291f user: drh tags: trunk) | |
| 21:27 | Add the SQLITE_DBCONFIG_ENABLE_VIEW option, together with a "db config" command in the TCL interface that can access that option as well as all the other sqlite3_db_config() boolean options. (check-in: 61b4bccd29 user: drh tags: trunk) | |
| 20:04 | Provide the SQLITE_DIRECTONLY flag for app-defined functions that prohibits the use of those functions within triggers or views. (Closed-Leaf check-in: fc745845d8 user: drh tags: directonly) | |
| 14:35 | Ensure that the optional "sz=N" parameter that can be manually added to the end of an sqlite_stat1 entry does not have an N value that is too small. Ticket [e4598ecbdd18bd82] (check-in: 98357d8c12 user: drh tags: trunk) | |
| 13:53 | Ensure that SQLite does not attempt to process incompatible window functions in a single scan. Fix for [256741a1]. (check-in: 4f5b2d9381 user: dan tags: trunk) | |
| 13:46 | Avoid downgrading SQLITE_CORRUPT errors detected by the schema parser into SQLITE_NOMEM or SQLITE_ERROR errors. (check-in: b2e79f8ff0 user: drh tags: trunk) | |

| 16:36 | Experimental implementation of NULLS FIRST/LAST. This branch still has problems - the most significant of which is that ORDER BY clauses with a non-default NULLS FIRST/LAST qualifier can never use an index. (check-in: 07babb0f89 user: dan tags: nulls-last) | |
| 16:25 | For the ".testctrl prng_seed" command in the CLI, if the argument is "random" then select a random integer seed and print the seed value on stdout. (check-in: 636ca4472c user: drh tags: trunk) | |

| 16:23 | More legacy STAT3 code removed. (Closed-Leaf check-in: 845d2f17de user: drh tags: omit-stat3) | |
| 15:24 | Remove support for STAT3. The sqlite_stat3 tables are ignored, if they exist. STAT4 continues to work as it always has, and as it is a superset of STAT3 is the recommended replacement. (check-in: 1e17ea2fd1 user: drh tags: omit-stat3) | |

| 18:34 | Add "set TMP=%CD%" to the start of each msvc script output by releasetest_data.tcl.
