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.

23:15

The expression "(X IS FALSE) IN (FALSE)" does not imply that X is NOT NULL. Ticket [f8f472cbc77ba9c9] (check-in: dd661348 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: 057fb8b1 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: 45ff2b1f user: drh tags: trunk)

23:24
Remove a faulty testcase() macro. (check-in: 80124ae5 user: drh tags: trunk)
21:16
Improve vdbe branch coverage of NULLS LAST code. (check-in: e8e9f77d user: dan tags: trunk)
19:34
Fix other problems similar to ticket [c0390363]. (check-in: 96ff2ba9 user: dan tags: trunk)
16:48
Add a missing VdbeCoverage() macro. (check-in: 33da6092 user: drh tags: trunk)
16:17
Remove an unreachable branch in the NULLS LAST logic of RANGE window functions. (check-in: 47cd634c user: drh tags: trunk)
15:50
Fix another case where SQLite assumes that if "~(? AND FALSE)" is true, "?" must be non-null. (check-in: 616f5663 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: 84ae41fd user: dan tags: trunk)
14:25
Fix a potential buffer overrun in fts5 caused by corrupted database records. (check-in: c465d0eb user: dan tags: trunk)
00:27
Improve Lemon so that it enlarges some of its tables slightly in order to avoid having to index range checks on table lookups for a performance increase. (check-in: 4be6a23a user: drh tags: trunk)
2019-08-28
11:49
Fix an unreachable branch in sqlite3ParserFallback() (Closed-Leaf check-in: e059178b 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: 47d3e091 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: bafd8723 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: 94085fb3 user: dan tags: trunk)
17:59
The ALWAYS() added by the previous check-in was incorrect. Take it back out. (check-in: 336235db 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: aff20980 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: 7f5168a7 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: 069c2f4c user: drh tags: trunk)
2019-08-26
20:41
Merge in recent fixes from trunk. (Closed-Leaf check-in: ad816d01 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: 279ac7fd user: dan tags: trunk)
14:18
Improved detection of number of column mismatch for vector assignment in UPDATE statements. Ticket [78acc9d40f0786e8] (check-in: bd4bda73 user: drh tags: trunk)
13:45
Fix typo in a comment. No code changes. (check-in: d0cc06d8 user: drh tags: trunk)
12:50
Enforce 80-character line discipline in the CLI. Minor improvements to the CLI built-in help. (check-in: 9690013a user: drh tags: trunk)
2019-08-24
21:02
Minor performance improvement for balance_nonroot(). (check-in: d7434cae user: dan tags: trunk)
17:11
Fix a potential buffer overrun in fts5 caused by corrupt database records. (check-in: 156d6128 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: e3249012 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: 12d2cf88 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: d26fdfa3 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: bfe79378 user: drh tags: nulls-last)
17:00
Additional simplifications of the WHERE loop code generator logic for NULLS LAST. (check-in: 1383680d 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: e3ed2f49 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: bf875e1a 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: 649b08ea user: drh tags: nulls-last)
2019-08-22
21:13
Add additional VDBE coverage macros. (check-in: d3531f5b 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: 63e625c8 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: 44578865 user: drh tags: trunk)
11:11
Fix a false-positive in sqlite3ExprNeedsNoAffinityChange(). Ticket [ac184eb571d5e6e0] (check-in: e62eddbb 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: 81b9f0f5 user: drh tags: trunk)
2019-08-21
19:58
Add missing VdbeCoverage() macros to new code. (check-in: b1cbcdc6 user: dan tags: nulls-last)
17:46
Disable broken test case in expert1.test. (check-in: 73e30c2e user: dan tags: nulls-last)
15:41
Update this branch with latest trunk changes. (check-in: 6153bcf4 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: d02490a2 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: 4c01e017 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: 00e9a8f2 user: dan tags: trunk)
17:14
Bring the hard-heap-limit branch up-to-date with trunk. (check-in: 9b14eb77 user: drh tags: hard-heap-limit)
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: 75aec4fc user: dan tags: trunk)
13:49
Add the new sqlite3_drop_modules() interface to the loadable extension mechanism. (check-in: 658bd516 user: drh tags: trunk)
11:43
Retain the affinity of an expression in a WHERE clause when it is transformed to a reference to an index column on the same expression. Fix for [f043b113]. (check-in: 511da081 user: dan tags: trunk)
02:19
Fix a typo and a harmless compiler warning. (check-in: ec4c63e0 user: mistachkin tags: trunk)
