| ||
| 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) | |
| 02:09 | Increase the size of the yy_lookahead table so that it is never necessary to down bounds checking on the index. (check-in: bafd872398 user: drh tags: lemon-optimization) | |
|
2019-08-27
| ||
| 19:59 | Add support for "ORDER BY ... NULLS FIRST" and "ORDER BY ... NULLS LAST". Use this to fix ticket [f8a7060e]. (check-in: 94085fb3e7 user: dan tags: trunk) | |
| 17:59 | The ALWAYS() added by the previous check-in was incorrect. Take it back out. (check-in: 336235db2b user: drh tags: trunk) | |
| 17:28 | Add ALWAYS() to an always true conditional that results from the previous check-in. Add a test case for ticket [dbaf8a6820be1ece] to supplement those already checked into TH3. (check-in: aff2098047 user: drh tags: trunk) | |
| 17:01 | Omit the "x IN (y)" to "x==y" optimization of check-in [e68b427afbc82e20] (and ticket [e39d032577df6942]) as it causes difficult affinity problems as demonstrated by ticket [dbaf8a6820be1ece] and the original assertion fault is no longer a factor due to countless other changes of the previous 5 years. (check-in: 7f5168a76a user: drh tags: trunk) | |
| 10:05 | If a TEMP TRIGGER references an auxiliary schema, and that auxiliary schema is detached, move the trigger to reference the TEMP schema before completing the detach, so that the trigger does not hold a dangling schema pointer. Ticket [ac8dd4a32ba4322f] (check-in: 069c2f4c61 user: drh tags: trunk) | |

| 20:41 | Merge in recent fixes from trunk. (Closed-Leaf check-in: ad816d01d4 user: drh tags: nulls-last) | |
| 14:57 | Tweak the shell tool ".recover" command so that it can recover rows that consist of a rowid and no fields. (check-in: 279ac7fdec user: dan tags: trunk) | |
| 14:18 | Improved detection of number of column mismatch for vector assignment in UPDATE statements. Ticket [78acc9d40f0786e8] (check-in: bd4bda73df user: drh tags: trunk) | |
| 13:45 | Fix typo in a comment. No code changes. (check-in: d0cc06d8a3 user: drh tags: trunk) | |
| 12:50 | Enforce 80-character line discipline in the CLI. Minor improvements to the CLI built-in help. (check-in: 9690013a00 user: drh tags: trunk) | |
|
2019-08-24
| ||
| 21:02 | Minor performance improvement for balance_nonroot(). (check-in: d7434cae3e user: dan tags: trunk) | |
| 17:11 | Fix a potential buffer overrun in fts5 caused by corrupt database records. (check-in: 156d612800 user: dan tags: trunk) | |
|
2019-08-23
| ||
| 23:05 | Fix the built-in edit() SQL function in the CLI so that it works with zero-length blobs. (check-in: e324901286 user: drh tags: trunk) | |
| 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) | |
|
2019-08-22
| ||
| 21:13 | Add additional VDBE coverage macros. (check-in: d3531f5be7 user: drh tags: nulls-last) | |
| 19:35 | Merge fixes from trunk. Also fix a reference to the KeyInfo.aSortOrder field, which should now be KeyInfo.aSortFlags (check-in: 63e625c8eb user: drh tags: nulls-last) | |
| 16:38 | Fix the likely(), unlikely(), and likelihood() functions so that they have no affinity, just like any other function. Ticket [7e07a3dbf5a8cd26] (check-in: 44578865fa user: drh tags: trunk) | |
| 11:11 | Fix a false-positive in sqlite3ExprNeedsNoAffinityChange(). Ticket [ac184eb571d5e6e0] (check-in: e62eddbb04 user: drh tags: trunk) | |
| 00:53 | Fix the OP_SeekGE, OP_SeekGT, OP_SeekLE, and OP_SeekLT opcodes so that they preserve the datatype of the value in the register used as the key. Ticket [d9f584e936c7a8d0] (check-in: 81b9f0f550 user: drh tags: trunk) | |
|

| 17:46 | Disable broken test case in expert1.test. (check-in: 73e30c2e92 user: dan tags: nulls-last) | |
| 15:41 | Update this branch with latest trunk changes. (check-in: 6153bcf41a user: dan tags: nulls-last) | |
| 14:54 | Avoid assuming that "column IS ?", where column is declared UNIQUE, matches only a single row (as "?" might be NULL). Fix for [b8689402]. (check-in: d02490a2f0 user: dan tags: trunk) | |
| 11:31 | Fix a broken assert() in the fts3 snippet code that was failing for queries containging more than 64 phrases. (check-in: 4c01e0170e user: dan tags: trunk) | |
|
2019-08-20

| 19:11 | Fix a problem with fts5 "ORDER BY rank" queries when the fts5 table name requires quoting. (check-in: 00e9a8f273 user: dan tags: trunk) | |
| 17:51 | Add tests for sort-by-index cases that use IN() and non-default NULL handling. (check-in: 09d660ecde user: dan tags: nulls-last) | |
| 17:14 | Bring the hard-heap-limit branch up-to-date with trunk. (check-in: 9b14eb7754 user: drh tags: hard-heap-limit) | |
| 15:47 | Do not pass ORDER BY clauses with non-standard NULL handling to virtual table implementations. (check-in: a9a82ee88d user: dan tags: nulls-last) | |
| 14:43 | Fix a segfault that could occur following an OOM while processing a SELECT statement for which one or more of the expressions in the window frame declaration are themselves sub-selects that use window functions. (check-in: 75aec4fc88 user: dan tags: trunk) | |
| 13:49 | Add the new sqlite3_drop_modules() interface to the loadable extension mechanism. (check-in: 658bd51623 user: drh tags: trunk) | |

| 02:19 | Fix a typo and a harmless compiler warning. (check-in: ec4c63e00c user: mistachkin tags: trunk) | |

| 20:35 | Omit the "_except" term from the name of the new interface. (Closed-Leaf check-in: e5ba47c2d8 user: drh tags: sqlite3_drop_modules_except) | |
| 19:59 | Fix problems with window frames that use ORDER BY ... NULLS LAST etc. (check-in: 75d665a494 user: dan tags: nulls-last) | |
| 17:26 | Prevent NULLS FIRST/LAST from being used in CREATE INDEX and other statements. (check-in: bb9767a287 user: dan tags: nulls-last) | |
