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. Leaf check-in: 0913ff4d user: drh tags: reuse-schema
13:04

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

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

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
20:40

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

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
21:14
Add another test case to cover a previously uncovered branch in the RBU module. check-in: 30392985 user: dan tags: trunk

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

18:49
Add tests to improve code coverage of the RBU module. check-in: ecb56b75 user: dan 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
00:17
Earlier detections of errors in the byte-offset-to-cell-content integer at offset 5 in the header of a btree page. check-in: a0819086 user: drh tags: trunk
2019-05-07
20:06

19:44

01:41
In the sqlite3_value or Mem object, make the MEM_IntReal type completely independent from MEM_Int and MEM_Real. This helps avoid problems when inserting non-float values into a "REAL" column. check-in: 5a8a23ee user: drh tags: trunk
01:29
New testcase macros to ensure that MEM_IntReal is fully tested. Closed-Leaf check-in: 8b8ef445 user: drh tags: int-real
2019-05-03
21:17
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

2019-05-02
21:36
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
17:45
Ensure that the typeof() function always returns SQLITE_FLOAT for floating point values even when the value is stored as an integer to save space. check-in: 48889530 user: drh tags: trunk
17:06
Add options to wapptest.tcl similar to those supported by releasetest.tcl. Also add the -noui switch, for running without wapp altogether. check-in: 005a1694 user: dan tags: trunk

01:41
The "LIKE Optimization" (which converts a LIKE into a BETWEEN operator that is able to use an index) does not work and cannot be used if the collating sequence of the column is not TEXT and if the pattern starts with a "+" sign. This is another case of ticket [c94369cae9b561b1f996d005]. The new test case was discovered by Manuel Rigger. check-in: b043a54c user: drh tags: trunk
00:52

18:59
When values have real affinity and are converted into strings for CHECK constraints or index expressions, do the conversions into a real-number format even if the values are stored as integers for efficiency. This appears to fix ticket [ae0f637bddc5290b446]. check-in: 5997d075 user: drh tags: trunk
17:36
Fix an incompatibility with -DSQLITE_OMIT_LOAD_EXTENSION=1 in dbdata.test. check-in: a77cd85b user: dan tags: trunk

13:48
Do not de-duplicate columns index columns associated with a WITHOUT ROWID table if the columns have different collating sequences. This is the fix for ticket [3182d3879020ef3b2]. There is one test case added, but most of the tests are done in TH3. check-in: 1b1dd4d4 user: drh tags: trunk
13:30
