Fix a problem with handling with handling quoted path elements in extension functions json_set() and json_insert() reported on the mailing list. Leaf check-in: 45bfcb88 user: dan tags: trunk
14:13
New sqlite3_db_config() options: SQLITE_DBCONFIG_LEGACY_ALTER_TABLE, SQLITE_DBCONFIG_DQS_DML, and SQLITE_DBCONFIG_DQS_DDL. check-in: a61db8ff user: drh tags: trunk

2019-06-16
14:56

2019-06-14

17:37
Deprecate the SQLITE_ALLOW_COVERING_INDEX_SCAN compile-time option when it is turned off. This probably will impact no-one.

Start-time disabling of covering index scan is not affected. check-in: 23e49f99 user: drh tags: trunk
13:24
Fix the implementation of the built-in RTRIM collating sequence so that it works for control characters at the end of the string. Ticket [f1580ba1b574e9e9] check-in: 86fa0087 user: drh tags: trunk
12:28
Refactor the LIKE optimization decision logic so that it uses sqlite3AtoF() on both boundary keys to determine if the optimization can be used when the LHS is something that might not have TEXT affinity.

16:43
Mark an unreachable branch with an ALWAYS macro. check-in: d4755aca user: drh tags: trunk

Off-by-one error in the CAST to NUMERIC logic. check-in: 25b89630 user: drh tags: trunk

02:43
The ALTER TABLE command should not attempt to rename objects that are contained within an expression tree that has been optimized out because it is the other branch of an "AND false" expression. Ticket [533010b8cacebe82] check-in: 04bd5cb7 user: drh tags: trunk
01:56
Fix repeated test numbers in the altertab2.test file. check-in: e82f235e user: drh tags: trunk

2019-06-10
23:45
A string consisting of a single '.' is not a floating point literal with extra text at the end. Fix for ticket [412bba9b22c677da] check-in: 57050162 user: drh tags: trunk
19:17
Have ALTER TABLE commands ignore the lhs of "expr IN ()" and "expr NOT IN ()" expressions, just as other queries do. Fix for [533010b8ca]. check-in: 71643deb user: dan tags: trunk
19:07

22:26
When casting string values into numeric and the string has a prefix that looks like a number but total string is not a well-formed number, then take extra care that the result is either integer or real depending on what the prefix looks like. Fix for tickets [e8bedb2a184001] and [4c2d7639f076aa]. check-in: 67a68af5 user: drh tags: trunk

17:22
Fix the query flattener optimization so that it preserve the "SF_Compound" bit when flattening a compound subquery into a non-compound outer query.

2019-05-28

2019-05-22
23:12
New test case for check-in [74ef97bf51dd531a] that takes the fix in the previous check-in into account. check-in: cb1d0652 user: drh tags: trunk
22:49
Renumber the Select.selId values in the copies of SELECT statements that implement VIEWs when the VIEW is expanded, so that when the same VIEW is used twice in the same join, each expansion as a distinct selId. This fixes ticket [ce823231949d3abf42453c8]. check-in: 3cacc4b9 user: drh tags: trunk
14:35
New dbsqlfuzz find added to test/fuzzdata8.db. check-in: 42af7c81 user: drh tags: trunk

18:43

18:35
A minor variation on check-in [1685610ef8e0dc] which (hopefully) makes the logic a little easier to follow. Also disallows the use of the double-quoted string hack in the query expression used for VACUUM INTO, which is not strictly required, but moves us toward the goal of disallowing the double-quoted string hack everywhere. check-in: 3e1b55f3 user: drh tags: trunk
17:14
Disallow string constants enclosed in double-quotes within new CREATE TABLE and CREATE INDEX statements. It is still possible to enclose column names in double-quotes, and existing database schemas that use double-quotes for strings can still be loaded. This addresses ticket [9b78184b]. check-in: 1685610e user: dan tags: trunk
10:36
Update the sqlite3ExprCompare() routine so that it does not think "? IS NOT TRUE" is the same as "? IS TRUE". Fix for [d3e7f2ba5b3]. check-in: 99eba69b user: dan tags: trunk
2019-05-18
21:22
Fix an assert() failure that could occur in a join query if the RHS of an IN() operator is a list containing correlated expressions.

19:49

2019-05-17
20:37
Disable PRAGMA journal_mode=OFF when SQLITE_DBCONFIG_DEFENSIVE is turned on. Ticket [f4ec250930342e0c]. check-in: a0f5eb5c user: drh tags: trunk
15:59

2019-05-16

03:47
Fix harmless compiler warning in the session extension. check-in: dff823ca user: mistachkin tags: trunk
01:22
Make sure the OP_Concat opcode always correctly zero-terminates a UTF16 string, even if the input strings are ill-formed. This is a followup to check-in [3a16ddf91f0c9c516a7] that fixes a case the previous check-in missed. Also add assert()s to prove correct zero termination. check-in: d612fb78 user: drh tags: trunk
2019-05-15
18:42
Fix the count-of-view optimization so that it is (correctly) disabled for a query that includes a WHERE clause or a GROUP BY clause. check-in: 05897ca4 user: drh tags: trunk

Fix a crash in the sqlite_dbdata module that could occur if a pointer within an overflow chain in a corrupt database pointed past the end of the db. check-in: 3eae4e30 user: dan tags: trunk
17:10
Disable the optimization where a REAL value with no fractional part is stored as an INTEGER when the integer uses as much space as the real value it proposes to stand in for (8 bytes). This avoids corner cases of comparing integers against real values that are beyond the resolution of an IEEE 754 double. Fix for ticket [6c1d3febc00b22d457c78c2] check-in: 9b091527 user: drh tags: trunk
16:57

Ensure that the sqlite3BtreeLast() interface initializes the *pRes return to zero if the cursor is already sitting on the last entry of the table. Manuel Rigger found the obscure test case for which this makes a difference. check-in: ebe4845c user: drh tags: trunk
23:53
This is part of the previous check-in that didn't get committed for some reason - probably because I failed to press the "Save" button on the text editor. check-in: 51d32173 user: drh tags: trunk

Simplification to the logic underlying PRAGMA case_sensitive_like. check-in: ef0015fd user: drh tags: trunk

Add the SQLITE_TESTCTRL_RESULT_INTREAL test-control and use it to create the intreal() SQL function in testfixture. Write a few simple tests to prove this all works. TH3 will hold most of the INTREAL tests, probably. check-in: c9838731 user: drh tags: int-real
19:34
Ensure that UTF16 strings are properly zero-terminated before returning them in an sqlite3_value_text16() request, even if the string is invalid UTF16 because it was formed from an arbitrary and/or odd-length BLOB. check-in: 3a16ddf9 user: drh tags: trunk

Make MEM_IntReal a completely independent type, meaning a floating point value stored as an integer. This fixes a problem with arithmetic within arguments to string functions on indexes of expressions. But it is a big change and needs lots of new testcase() macros for MC/DC and so it is initially put on this branch. check-in: dba836e3 user: drh tags: int-real
