50 check-ins occurring around 23ec34e4f6177519.

2019-05-22
14:35
New dbsqlfuzz find added to test/fuzzdata8.db. check-in: 42af7c819b user: drh tags: trunk
14:22
Fix a buffer overread that could in fts3 when dealing with corrupt records. check-in: 1660d7733e user: dan tags: trunk
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: b3692c406f user: drh tags: trunk
16:32
Fix a problem in [b5ca442a] causing an assert() to fail in REINDEX commands. check-in: a3e77c7776 user: dan tags: trunk
14:42
Use a statement journal for all CREATE INDEX statements in case an indexed exprsesion throws an exception when it is evaluated. Fix for [b5ca442a]. check-in: b8071d10cb user: dan tags: trunk
2019-05-20
19:46
Fix a segfault that could occur in sqlite3session_diff() if NULL were passed as the pzErrMsg argument. check-in: aee73fd28f user: dan tags: trunk
18:43
Improvements to the automatic compile-time selection of byte-order, as suggested on the mailing list by Seb Kemper. check-in: b7aad92961 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: 3e1b55f3ab 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: 1685610ef8 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: 99eba69b3a 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: 778b1224a3 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: d91095ba71 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: a0f5eb5c79 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: 14c00b1016 user: dan tags: trunk
2019-05-16
20:40
Add test cases to test/fuzzdata7.db for (harmless) dbfuzz2 finds. check-in: 1eb2a628e4 user: drh tags: trunk
20:36
Initialize the 18-byte overrun area on the buffer used to reconstruct overflow btree cells during a btree search, to avoid a harmless jump-depends-on-uninit-values warning. check-in: 4b05caeb1b user: drh tags: trunk
20:13
Fix an assert() in the OP_Delete opcode that could fail with a corrupt database. check-in: 915388ab39 user: dan tags: trunk
16:44
Add new test file fts5corrupt4.test. check-in: 5dfc4fe98a user: dan tags: trunk
11:47
Fix a harmless use-of-initialized-value fault in the assert() logic added by check-in [d612fb7873cf59d] check-in: 3dac90728a user: drh tags: trunk
03:47
Fix harmless compiler warning in the session extension. check-in: dff823ca8b 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: d612fb7873 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: 05897ca48a user: drh tags: trunk
10:16

20:25
Fix a problem with the fix for [9cf6c9bb51] (commit [658b84d7]) that could cause a cursor to be left in an invalid state following a (rowid < text-value) search. check-in: bc7d2c1656 user: dan tags: trunk
19:39

A new implementation for the sqlite3ExprImpliesExpr() theorem prover that does a better job of answering TRUE to "(NOT A) OR B" when B is a NOT NULL expression. check-in: b3413197f5 user: drh tags: trunk
16:14
When considering partial indexes, do not assume that a "CASE x ..." expression implies "x IS NOT NULL". check-in: 1b24303220 user: dan tags: trunk
13:04
Do not assume that "x IS NOT ?" implies "x NOT NULL" when considering partial indexes. Fix for ticket [8025674847]. check-in: 0ba6d709b5 user: dan tags: trunk
