| 16:37 | Attempt to further generalize the min/max optimization so that, if an appropriate index exists, it can be used by any aggregate query that contains only a single aggregate of the form max(colname) or min(colname) and does not contain a GROUP BY clause. Closed-Leaf check-in: 7280e14c user: dan tags: minmax-opt | |

| ||
| 22:19 | When an arithmetic operation with two integer operands must give a floating-point answer due to overflow, make sure the answer is not rounded back to integer by affinity. check-in: bd7aeeb6 user: drh tags: trunk | |
| 10:22 | Modify releasetest.tcl so that it runs the "checksymbols" test on a build without SQLITE_DEBUG defined. If SQLITE_DEBUG is defined, the sqlite3WhereTrace variable causes the test to fail. check-in: 75e545a9 user: dan tags: trunk | |
| 09:08 | Remove a reference to JumpOnce from a comment in vdbe.c. No code changes. check-in: ee662c03 user: dan tags: trunk | |

| 23:37 | Pull the latest trunk changes into the sessions branch, and in particular the collating-sequence refactorization. check-in: 4f6d69ae user: drh tags: sessions | |
| 22:14 | Factor some work out of the index loop of the bestBtreeIndex() routine for a small performance increase. check-in: 92c9ab56 user: drh tags: trunk | |
| 21:51 | Refactor collating-sequence handling as a fix for ticket [71e333e7d2e642]. The Expr.pColl field is removed from the Expr object. The COLLATE operator now becomes a separate instance of Expr in the expression tree. The code generator looks up the correct collating function as needed, rather than referring to Expr.pColl. check-in: 8542e618 user: drh tags: trunk | |
| 21:36 | Adjustments to the collating-sequence refactoring to facilitate full-coverage testing and to fix some minor issues found by TH3. Closed-Leaf check-in: cdbfa664 user: drh tags: ticket-71e333e7 | |
| 14:16 | Make sure WHERE clause constraints A=B and B=A work the same even with COLLATE clauses. check-in: b3f53668 user: drh tags: ticket-71e333e7 | |
| 13:26 | Fix the header comment on the OP_Compare operator. check-in: 2722f407 user: drh tags: ticket-71e333e7 | |
| 06:46 | Merge updates from trunk. check-in: e65db42c user: mistachkin tags: configReadOnly | |
| 04:10 | Duplicating check constraint expressions prior to code generation is no longer required, and so it is removed. check-in: 1a9db8dc user: drh tags: ticket-71e333e7 | |
| 03:34 | Veryquick passes all tests now. check-in: 7b96115e user: drh tags: ticket-71e333e7 | |
| 00:52 | Recognize TK_COLLATE operators that have been transformed into TK_REGISTER. Skip both TK_COLLATE and TK_AS operators when looking for the top of an expression. check-in: f66c1db2 user: drh tags: ticket-71e333e7 | |

| 22:54 | Do not report missing collating functions while parsing the schema. Also remove a stray comment. check-in: e313edca user: drh tags: ticket-71e333e7 | |
| 22:18 | Fix a long-standing issue with the distinct-as-aggregate optimization that only expressed when the new collating-sequence logic is turned on. check-in: 0aaf52a3 user: drh tags: ticket-71e333e7 | |
| 21:02 | Fix the processing of ORDER BY clauses with COLLATE terms on compound queries. 52 veryquick test failures remain. check-in: 49654453 user: drh tags: ticket-71e333e7 | |
| 20:31 | Many more tests are passing. Only about 100 failures remain in veryquick. check-in: f9fa7581 user: drh tags: ticket-71e333e7 | |
| 19:28 | Ensure the VerifyCookie sub-routine has been run before the database is accessed in an obscure case. Fix for ticket [d6b36be38]. check-in: 2d5f37c9 user: dan tags: trunk | |
| 18:38 | Some errors in veryquick resolved. Many more to go. check-in: 972443b4 user: drh tags: ticket-71e333e7 | |
| 14:02 | Veryquick now runs to completion without segfaulting or asserting. But there are still lots of errors. check-in: 7fafab12 user: drh tags: ticket-71e333e7 | |
| 10:55 | Do not run test file malloc3.test as part of the inmemory_journal permutation. Explanation is in a comment at the top of malloc3.test. check-in: df1827b1 user: dan tags: trunk | |

| 23:16 | In the async VFS, treat the new error code SQLITE_IOERR_DELETE_NOENT as success for xDelete. check-in: c507ca4a user: mistachkin tags: trunk | |
| 21:16 | Remove the Expr.pColl field and compute the collating sequence as it is needed. This fixes the test script "shared9.test", though there is still a memory leak. And there are other problems. Consider this a work-in-progress. check-in: fd011cb2 user: drh tags: ticket-71e333e7 | |
| 20:27 | Cherrypick [79ef8e3c77] (Apply the same restrictions on constant refactoring to statements within a trigger program as top-level statements). Leaf check-in: 34aafb74 user: dan tags: branch-3.7.9 | |
| 20:19 | Cherrypick [557c69055a3] and [0064bab7714] (OP_Once-related fixes for triggers). check-in: 0d7b5d45 user: dan tags: branch-3.7.9 | |
| 19:41 | Merge the constant-refactoring-in-triggers branch with the trunk. check-in: 79ef8e3c user: dan tags: trunk | |

| 19:01 | Add the SQLITE_FCNTL_TEMPFILENAME file control that asks the underlying VFS to return a new temporary filename. Per request from NSS team at Mozilla. check-in: 1a63b1d5 user: drh tags: trunk | |
| 15:15 | Add a test case that demonstrates ticket [71e333e7d2e642]. check-in: cc6e0785 user: drh tags: ticket-71e333e7 | |

| 19:04 | Disable a couple of tests in where.test when running the "no_optimization" permutation. check-in: 5e961e37 user: dan tags: trunk | |
| 16:44 | Modify a query in test/thread001.test to ensure that results are returned in the order expected by the test. check-in: 51cbddd5 user: dan tags: trunk | |
| 14:37 | Fixes to a test case in shared_err.test. The fix is to prevent sqlite3_prepare() from being called when the test intends to test the response of sqlite3_step() to an OOM condition. check-in: 40c14395 user: dan tags: trunk | |
| 14:31 | Make sure memory is freed using a routine that is compatible with the routine used to allocate the memory. The SQLITE_MEMDEBUG compile-time option enforces this. check-in: 9f6c6885 user: drh tags: trunk | |
| 11:30 | Since errors are ignored anyway, use sqlite3OsFileControlHint() instead of OsFileControl() to invoke the SQLITE_FCNTL_BUSY_HANDLER file-control. check-in: bdceca27 user: dan tags: trunk | |
| 10:01 | If the atomic-write property is enabled, a transaction may be committed in journal_mode=DELETE mode without ever actually creating a journal file on disk. In this case, do not attempt to unlink() the journal file when committing the transaction. check-in: 11aa47b0 user: dan tags: trunk | |
| 09:12 | Update a couple of test scripts so that they work in auto-vacuum mode. check-in: 04ab2dc6 user: dan tags: trunk | |

| 11:03 | Fix a harmless compiler warning. check-in: 12693deb user: drh tags: trunk | |
| 05:24 | Add a test to ensure that the fix in [b0c1ba655d] has worked. check-in: 41806de5 user: dan tags: trunk | |

| 19:42 | Remove an unreachable condition. Replace it with an assert(). check-in: 7d5fc1a3 user: drh tags: trunk | |
| 17:04 | Make sure that the optimization that set the maximum column that will be used on a particular query does not mistakenly change an opcode other than OP_OpenRead or OP_OpenWrite. In particular, make sure it does not overwrite the P4 field of an OP_SorterOpen. check-in: b0c1ba65 user: drh tags: trunk | |

| 20:21 | Do not exit the command-line shell if a ".read" command invokes a script that contains two errors. But reported on the mailing list. check-in: 2e5e6515 user: drh tags: trunk | |
|
2012-11-29

| 02:10 | In winDelete, determine that a file does not exist by checking for a last error of ERROR_FILE_NOT_FOUND or ERROR_PATH_NOT_FOUND. Closed-Leaf check-in: 692ad3c0 user: mistachkin tags: winNotFound | |
|
2012-11-20
| ||
| 15:06 | Have the windows implementation of xDelete return SQLITE_IOERR_DELETE_NOENT if the file to be deleted does not exist. The unix implementation was previously modified to behave this way. The current changes simply brings the two implementations into alignment. check-in: d4c36d49 user: drh tags: trunk | |

| 11:16 | Strive to use posix_fallocate() rather than ftruncate() when posix_fallocate() is available. Ticket [5eaa61ea18]. check-in: 29980b08 user: drh tags: trunk | |
| 11:08 | Use preprocessor macros to automatically detect whether or not posix_allocate() is available. (It is generally available on Linux but not on Mac.) Ticket [5eaa61ea1881040b17449ca043b6f8fd9ca55dc3] Closed-Leaf check-in: 597333f1 user: drh tags: tkt-5eaa61ea18 | |
| 10:54 | When available, use posix_fallocate() rather than ftruncate() to allocate space for mmap()ed -shm files, since posix_fallocate() gives an error if no disk space is available whereas ftruncate() is silent and leaves the system vulnerable to a SIGBUS upon first write to the mmap()ed region. Ticket [5eaa61ea1881040b17449ca043b6f8fd9ca55dc3] check-in: 35625961 user: drh tags: tkt-5eaa61ea18 | |

|
2012-11-09
| ||
| 21:40 | Only log unlink() errors if the error is something other than SQLITE_IOERR_DELETE_NOENT. The error is still reported up the stack, it is simply not added to the sqlite3_log(). check-in: 5a3b07f0 user: drh tags: trunk | |
| 20:17 | Change os_unix.c to propagate ENOENT errors back to sqlite as SQLITE_IOERR_DELETE_NOENT. Have SQLite ignore these where they are benign and propagate them back to the caller where they may indicate a file-system malfunction of some description. check-in: bed9c172 user: dan tags: trunk | |
| 18:32 | Take into account the cost of inner loops when selecting which table of a join to use for the next outer loop. check-in: 3f87f459 user: drh tags: trunk | |
| 18:22 | Disable the table selection rule that tried to prevent full table scans from migrating to the outer loop unless they were optimal. The new scaling of outer-loop costs by cost of inner loops obviates the need for that step. And, in fact, that step causes problems with the new inner-loop cost accounting. Closed-Leaf check-in: 51bfd63b user: drh tags: inner-loop-cost | |
