66 check-ins using file src/func.c version 08d6d07d

2019-06-03
14:02
Updates to the shared_schema.md notes document. check-in: 51af2ade user: drh tags: reuse-schema
13:46
In the CLI, add ".help" text for the .shared-schema command. check-in: 3ba6f790 user: drh tags: reuse-schema
2019-05-30
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
Fix a memory leak in the delta_parse() table-valued function of the fossildelta.c extension. check-in: c86ca3f0 user: drh tags: trunk

Improved rounding even on systems with an 8-byte "long double" type. check-in: 15202aee user: drh tags: trunk
2019-05-25
18:17
Performance enhancement in sqlite3AtoF(). About 8% faster. check-in: 81721aa5 user: drh tags: trunk

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
Add test cases for the fix in the previous commit. check-in: c1057b2a user: dan tags: trunk
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
Fix a problem in [b5ca442a] causing an assert() to fail in REINDEX commands. check-in: a3e77c77 user: dan tags: trunk
14:42

19:46

18:43
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
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
11:47
Fix a harmless use-of-initialized-value fault in the assert() logic added by check-in [d612fb7873cf59d] check-in: 3dac9072 user: drh tags: trunk
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
Simplify the "Verifying Code Authenticity" section of the README.md file. No code changes. check-in: adebffc1 user: drh tags: trunk

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: bc7d2c16 user: dan tags: trunk
19:39
Merge recent enhancements from trunk into apple-osx. check-in: 40362d51 user: drh tags: apple-osx

11:33
Fix an assert() and potential buffer overrun in fts5 that could occur if the database was corrupt. check-in: 8be8bd0d user: dan tags: trunk
00:43
Disable index seek optimizations on REINDEX when the order of primary keys in the index differs from the main table. Fix for ticket [bba7b69f9849b5bf11b4]. check-in: f7aadfab user: drh tags: trunk
2019-05-13
11:52
Fix an assert() failure in fts5 that could occur when processing a corrupt database. check-in: f158c048 user: dan tags: trunk
2019-05-11

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

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
