2019-09-03
16:23
Updates to the default settings in Makefile.linux-gcc. check-in: 3044cf69 user: drh tags: trunk
14:27
When we play games with COLLATE in order to commute an operator in the WHERE clause processing, be sure not to use the commuted operator to qualify a partial index, as insufficient COLLATE information is preserved to verify that the expression will correctly qualify the index.

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: 0c946f08 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.

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: e0d909c7 user: drh tags: trunk
23:15
Make sure OP_RealAffinity has been applied to all columns of type REAL in the excluded.* pseudo-table of an UPSERT. Ticket [5a3dba8104421320] check-in: 67381dad 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

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

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

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

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

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

2019-08-14
15:17
Always check for reads past the end of the file on the in-memory journal driver. This used to be an assert(). check-in: 4d41ca7d user: drh tags: trunk

Fix harmless compiler warnings. check-in: 1eef4dde user: drh tags: trunk
19:19
Remove support for SQLITE_ENABLE_STAT3. The sqlite_stat3 table is now ignored, if it exists. Run ANALYZE using STAT4 to get the equivalent functionality, which presumably everybody has been doing for a long time now. check-in: f1cd234c user: drh tags: trunk

Ensure that when the col in an operator like "val IN(col)" is a column of a view, its affinity is not used to coerce val. Fix for [0a5e2c1d]. check-in: 17b3d221 user: dan tags: trunk
20:55
Improved reuse of file descriptors for which close() is delayed to prevent clearly of posix advisory locks. check-in: 509c1ba2 user: drh tags: trunk

Performance optimization to the new affinity handling logic. Closed-Leaf check-in: c9724e76 user: drh tags: pending
14:37
Use 0x40 (ASCII '@') instead of 0x00 to mean "no affinity" so that columns with no affinity can appear in a zero-terminated string. Use the new SQLITE_AFF_NONE macro for this new magic number. check-in: e8234f69 user: drh tags: pending
2019-08-05
20:53
Ensure that columns of views and sub-queries that are expressions with no affinity are not assigned BLOB affinity. This matches the documentation. Fix for [61c853857f40da49]. (On a branch because there are still subtle issues.) check-in: e15a0977 user: dan tags: pending

19:32
One of two options on how to address ticket [61c853857f40da49]. In this mode, we back out the documentation change of [07b7749da88d54e5] and change the core to work as it has been documented to work since 2017, rather than how it has actually worked since 2009. check-in: 09cd0c0c user: drh tags: tkt-61c853-A
18:01

Add the SQLITE_TESTCTRL_PRNG_SEED which can control the PRNG seed either directly or through the schema cookie of a supplied database connection. check-in: 2660e929 user: drh tags: trunk
01:39
Give the SQLITE_TESTCTRL_PRNG_SEED two arguments. The second argument if not NULL is a pointer to a database connection which seeds the connection from its schema cookie. In this way, fuzzers can control the PRNG seed. Closed-Leaf check-in: 49aa3448 user: drh tags: prng-seed-test-control
2019-08-02

22:48
The sqlite3_set_authorizer() interface should only expire prepared statements when it is setting a new authorizer, not when clearing the authorizer. And statements that are running when sqlite3_set_authorizer() is invoked should be allowed to continue running to completion. check-in: 961e2f08 user: drh tags: trunk

14:22
Improved fix for ticket [ced41c7c7d6b4d36] that keeps skip-scan enabled, but avoids identifying a skip-scan as order-distinct (because it is not) and thus forces a separate b-tree to implement the DISTINCT clause of a query. This undoes check-in [a871d69c6de65038] and substitutes a new fix. check-in: 89bf0399 user: drh tags: trunk
