100 check-ins occurring around bc7d2c1656396bb4.

2019-05-30
13:47
Optimization to the round() SQL function for large input values without a fractional part. check-in: e95138f5 user: drh tags: trunk
00:46
Smaller and faster sqlite3IsNaN() implementation makes deserialization of floating point values much faster. check-in: ea748ede user: drh tags: trunk
2019-05-29
21:18
Much faster implementation of applyNumericAffinity() by avoiding some unnecessary calls to sqlite3Atoi64(). check-in: c1d8a3f6 user: drh tags: trunk
18:33
Add an assert() as an additional test for fix in check-in [523b42371122d9e1b3]. check-in: f9e85e6c 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. Failure to preserve that bit could allow subsequent flattenings which are not valid. Fix for ticket [c41afac34f15781fe09cd]. check-in: 523b4237 user: drh tags: trunk
2019-05-28
14:42

2019-05-27
11:21
Fix an error message on the blobread() extension function so that it says "read" instead of "write". check-in: 7cbb9a5f user: drh tags: trunk
11:09

2019-05-25
18:17
Performance enhancement in sqlite3AtoF(). About 8% faster. check-in: 81721aa5 user: drh tags: trunk
17:41

2019-05-24
22:58
Improvements to rounding behavior in the round() and printf() functions. check-in: 641b2d21 user: drh tags: trunk
13:15
The ".shared-schema" command in the CLI requires the sqlite_dbpage table, so disable it if the build does not include that extension. check-in: 0913ff4d user: drh tags: reuse-schema
13:04
Merge recent enhancements from trunk. check-in: ff9f3e09 user: drh tags: reuse-schema
11:55
Fix an fts5 segfault that could occur after parsing a corrupt structure record. check-in: 600daa9c user: dan tags: trunk
2019-05-23
16:40

16:38
Improvements to the view-self-join optimization so that it works on all VIEWs, not just on Common Table Expressions. check-in: d2fe370c user: drh tags: trunk
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
14:22

2019-05-21
17:04
Combine the implementations of the key and hexkey pragmas into a single case. Have both pragmas return "ok" if they are implemented. check-in: b3692c40 user: drh tags: trunk
16:32

Improvements to the automatic compile-time selection of byte-order, as suggested on the mailing list by Seb Kemper. check-in: b7aad929 user: drh tags: trunk
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. This problem was introduced by checkin [e130319317e7611938] which was part of the fix for ticket [787fa716be3a7f650c] - so this commit is part of that ticket's fix too. check-in: 778b1224 user: dan tags: trunk
19:49
Avoid including the comment in the output of "PRAGMA table_info" in situations where there is a comment following a DEFAULT value within a CREATE TABLE statement. check-in: d91095ba user: dan tags: trunk
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
Always store a REAL value in a column with REAL affinity if the integer equivalent would require 8 bytes of storage. Fix for [3c27b97e3]. check-in: 14c00b10 user: dan tags: trunk
2019-05-16
20:40
Add test cases to test/fuzzdata7.db for (harmless) dbfuzz2 finds. check-in: 1eb2a628 user: drh tags: trunk
20:36

20:13
Fix an assert() in the OP_Delete opcode that could fail with a corrupt database. check-in: 915388ab user: dan tags: trunk
16:44

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
10:16

2019-05-10
20:44

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

2019-05-08
23:55
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

19:32
Simplification to the logic underlying PRAGMA case_sensitive_like. check-in: ef0015fd user: drh tags: trunk
19:06

18:49
Add tests to improve code coverage of the RBU module. check-in: ecb56b75 user: dan tags: trunk
17:27
Provide the SQLITE_OMIT_CASE_SENSITIVE_LIKE_PRAGMA compile-time option to omit the case_sensitive_like pragma. This change, in combination with documentation changes, is the current solution to ticket [a340eef47b0cad5]. check-in: eabe7f2d user: drh tags: trunk
11:52

04:33
Remove an ALWAYS() that was previously added by check-in [a0819086] but which turns out can sometimes be false. check-in: ad8fc5d8 user: drh tags: trunk
03:34
Remove a NEVER() that was added in the previous check-in [a0819086a521f] because it is in fact reachable. check-in: 74eba255 user: drh tags: trunk

2019-05-07
20:06

19:44
