| 19:21 | Add test cases for the fix on this branch. (Closed-Leaf check-in: 2e31abe0 user: dan tags: tkt-e63cbcfd) | |
| 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) | |
| 16:37 | Optimize the restarting of an RBU vacuum. (check-in: 82062351 user: dan tags: trunk) | |
| 16:28 | Remove some redundant code from sqlite3rbu.c. Add test cases for RBU vacuum. (Closed-Leaf check-in: 7b051698 user: dan tags: rbu-opt) | |
| 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) | |
|
2019-05-06
| ||
| 20:40 | Optimize further cases of restarting an RBU vacuum. (check-in: 6b3261bf user: dan tags: rbu-opt) | |
| 16:15 | Fix a problem with renaming an INTEGER PRIMARY KEY column of a WITHOUT ROWID table using ALTER TABLE. (check-in: 91f701d3 user: dan tags: trunk) | |
|
2019-05-04
| ||
| 20:04 | Optimize some cases of restarting an RBU vacuum. (check-in: cdc09867 user: dan tags: rbu-opt) | |
| 17:32 | Fix the NOT NULL logic in the theorem prover that determines when a partial index can be used. Ticket [5c6955204c392ae763a95]. (check-in: c2e439bc user: drh tags: trunk) | |
| 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) | |
| 18:50 | Fix a memory-leak/segfault caused by using OP_OpenDup and OP_OpenEphemeral on the same VM cursor. (check-in: a9b90aa1 user: dan tags: trunk) | |
| 17:19 | Fix a problem where self-joins on views that are aggregate queries may return the wrong result. (check-in: 74ef97bf user: dan 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) | |
| 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 (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
| ||
| 19:01 | Add a test case for ticket [ae0f637bddc5290b44669e066a]. (check-in: ece48169 user: drh tags: trunk) | |
| 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) | |
| 17:32 | Fix a case in wapptest.tcl where a failed test might report 0 errors. (check-in: 2be1ed70 user: dan 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) | |
| 15:25 | Update wapptest.tcl so that it deletes extra files if the "Keep files:" checkbox is clear. Set it by default. (check-in: 09623cc4 user: dan tags: trunk) | |
| 14:41 | In "PRAGMA vdbe_trace" output, show the results of OP_Affinity opcodes. (check-in: 56604bb6 user: drh tags: trunk) | |
| 08:48 | Fix an incompatibility with auto-vacuum mode in new test script recover.test. (check-in: 36dd5b08 user: dan tags: trunk) | |
|
2019-04-30
| ||
| 20:43 | Update wapptest.tcl to use a simpler slave script. And to leave scripts wapptest_configure.sh and wapptest_make.sh in each test directory. (check-in: 07e527d7 user: dan tags: trunk) | |
| 15:36 | Fix a problem allowing a Table object to be deleted from within a call to the xDestroy method of the associated virtual table, causing a use-after-free error. (check-in: 1dbbb010 user: dan tags: trunk) | |
| 14:26 | Fix an error message in the Lemon parser generator. (check-in: b6d7d42b user: drh tags: trunk) | |

| 01:08 | Slightly smaller and faster implementation of the OP_MakeRecord opcode. (check-in: 3bdce7ef user: drh tags: trunk) | |
|
2019-04-29
| ||
| 16:44 | Changes to oserror.test so that it works even on systems that allow an unusually large number of file descriptors. (check-in: a27b0b88 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) | |
| 11:27 | Fix a stack overflow that could occur when renaming a table that has a trigger containing a window function invocation that itself contains a specific syntax error. (check-in: c621fc66 user: dan tags: trunk) | |
|
2019-04-28
| ||
| 19:27 | Take collating sequence into account when removing redundant columns from indexes on WITHOUT ROWID tables. This is the first proof-of-concept fix for ticket [3182d3879020ef3]. More testing needed. (check-in: b34fa5bf user: drh tags: tkt-3182d38790) | |
