| 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
| ||
| 20:36 | 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 | |
| 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 | |
| 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 | |
|
2019-05-14

| 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. Leaf check-in: 40362d51 user: drh tags: apple-osx | |
| 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 | |
|
2019-05-11
| ||
| 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 | |

| 14:34 | Ensure that the BtShared.nPage value is reset correctly on a SAVEPOINT ROLLBACK. check-in: e6d5fee8 user: drh 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 | |
| 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 | Fix the round() SQL function so that it handles infinities correctly. check-in: db9acef1 user: drh tags: trunk | |
|
2019-05-09

| 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 | |
| 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 | Avoid long delays that can occur when ".recover"ing data from a database with a corrupt freelist. check-in: 20f06bf2 user: dan tags: trunk | |

| 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 | |
| 19:55 | Fix another pattern for which the LIKE optimization does not work for a non-TEXT affinity. Case found by Manuel Rigger. check-in: 74020110 user: drh tags: trunk | |
| 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 | |
| 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 | |
| 11:42 | Fix VDBE opcodes OP_SeekLT and OP_SeekLE so that they work on intkey tables with non-numeric text values. Closed-Leaf check-in: a870c196 user: dan tags: tkt-9cf6c9bb | |
| 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 | |
|
2019-05-07

| 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 | |
| 19:13 | On an INSERT or UPDATE, generate the new table record prior to running foreign key checks, in case the foreign key checks changes datatypes on the registers holding column values. Proposed fix for ticket [e63cbcfd3378afe6980d626]. check-in: 3f1c8051 user: drh tags: tkt-e63cbcfd | |
| 17:47 | Strive to prevent harmless compiler warnings in GCC 4.8.5. check-in: 8b6691f6 user: drh tags: trunk | |
| 02:57 | Add the exprNodeCopy() routine that will safely memcpy() an Expr node that might be a size-reduced node. Leaf check-in: ab2ba8e7 user: drh tags: expr-node-copy-patch | |

| 03:56 | Fix harmless compiler warning seen with MSVC. check-in: 5862b83e user: mistachkin tags: trunk | |
| 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 | |

| ||
| 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 | |
| 15:56 | Earlier detection of a database corruption case in balance_nonroot(), to prevent a possible use of an uninitialized variable. check-in: c509d8a8 user: drh tags: trunk | |
| 14:15 | Merge enhancements from trunk Leaf check-in: 3a4751a9 user: drh tags: hard-heap-limit | |
| 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 | Fix an issue (discovered by OSSFuzz) in the enhanced OP_Concat operator from check-in [713caa382cf7dd] earlier today. check-in: 3e897702 user: drh tags: trunk | |
|
2019-05-01

| 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 | |
| 15:32 | Avoid unwelcomed side effects on the input operands in the OP_Concat operator. Fix for ticket [3be1295b264be2fac49b681] check-in: 713caa38 user: drh tags: trunk | |
| 14:41 | In "PRAGMA vdbe_trace" output, show the results of OP_Affinity opcodes. check-in: 56604bb6 user: drh 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 | Improved header comment and precondition checking for the new isDupColumn() function. Closed-Leaf check-in: 740d5ff6 user: drh tags: tkt-3182d38790 | |
| 11:41 | Fix a buffer overwrite in shell.c.in (part of the new .recover code). check-in: 92facbc7 user: dan tags: trunk | |
