53 check-ins using file src/pragma.c version 2e9fbfcb

2019-05-17
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

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: 4b05caeb user: drh tags: trunk
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
Add new test file fts5corrupt4.test. check-in: 5dfc4fe9 user: dan tags: trunk

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 an assert() failure in fts5 that could occur when processing a corrupt database. check-in: f158c048 user: dan tags: trunk
2019-05-11
19:36
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: b3413197 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: 1b243032 user: dan tags: trunk

17:50
Fix harmless compiler warnings in the CLI. check-in: 2846bc04 user: drh tags: trunk

Fix some harmless compiler warnings. Closed-Leaf check-in: ca068d82 user: mistachkin tags: warnings

14:26
Treat integer values in window definition ORDER BY clauses as constants, not as references to another expression. check-in: 7e4809ea user: dan tags: trunk
14:03
Improved comments and extra assert() statements on the OP_Savepoint opcode, just to make the code a little easier to read and reason about. check-in: e80b2d9f user: drh tags: trunk
12:14
Fix the previous check-in [db9acef14d492121] so that the amalgamation build works for systems for which lack HAVE_ISNAN. check-in: 3cc55e09 user: drh tags: trunk
12:06

2019-05-09
18:37
Fix another small buffer overread in sqlite_dbdata triggered by a corrupt database page. check-in: 1dfc95b8 user: dan tags: trunk
18:33
Fix a problem in the ".recover" command allowing a circular loop of b-tree pages in a database file to cause an infinite loop. check-in: 8d2a062e user: dan tags: trunk
18:13
Make the ".schema" command in the CLI resistant to corrupt database files. check-in: f22c7e22 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

15:51
Fix another corruption related buffer overread in the sqlite_dbdata module. check-in: 5cd728fb user: dan tags: trunk

11:18
Improved error handling for the ".open --hexdb" command of the CLI. check-in: 4fa831d5 user: drh tags: trunk
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
21:14

19:32
Simplification to the logic underlying PRAGMA case_sensitive_like. check-in: ef0015fd user: drh tags: trunk
19:06
Avoid an excess register allocation in UPDATE, when possible. This improves speed (slightly) and reduces the code footprint. check-in: 8658574e user: drh tags: trunk
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
