| 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 | |

|
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 | 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: b8071d10 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: aee73fd2 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: 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 | |
|

| 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 | |

| 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
| ||
| 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 | |
| 13:04 | Do not assume that "x IS NOT ?" implies "x NOT NULL" when considering partial indexes. Fix for ticket [8025674847]. check-in: 0ba6d709 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 | |

| 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 | Add another test case to cover a previously uncovered branch in the RBU module. check-in: 30392985 user: dan 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 | |
| 11:52 | Fix VDBE opcodes OP_SeekLT and OP_SeekLE so that they work on intkey tables with non-numeric text values. Fix for [9cf6c9bb]. check-in: 658b84d7 user: dan tags: trunk | |
| 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 | |
| 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 | |

| 20:06 | Generate all records for INSERT or UPDATE prior to running foreign key constraint checks, since the FK checks might modify the datatype of registers used to generate the records. Fix for ticket [e63cbcfd3378afe6980d6]. check-in: 3c75605b user: drh tags: trunk | |
| 19:44 | Do not commit an "OR FAIL" statement that causes foriegn key constraint violations. check-in: 659c551d user: dan tags: trunk | |

|
2019-05-03
| ||
| 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 | |
