2012-12-17
20:57
Add to the foreign_key_check pragma an extra output column "parent" that contains the name of the parent table for the constraint that failed. check-in: 97f7f737 user: drh tags: foreign-key-check
20:40
Enhance the error message for "foreign key mismatch" to include the names of the child and parent tables. Begin adding test cases for PRAGMA foreign_key_check. Make sure PRAGMA foreign_key_check gets all necessary table locks. check-in: 0f996352 user: drh tags: foreign-key-check
18:43
"PRAGMA foreign_key_check" with no argument checks the foreign keys on all tables. check-in: 57d47423 user: drh tags: foreign-key-check
18:05
Fix an issue with child keys that are not INTEGER PRIMARY KEY referencing INTEGER PRIMARY KEY in the parent. check-in: 603b695b user: drh tags: foreign-key-check

Remove an unreachable branch. Improvements to comments. Closed-Leaf check-in: d2fb7619 user: drh tags: vtab-IN-opt
15:54
Merge in all the trunk changes that have occurred since this branch was opened. check-in: 6d507e4d user: drh tags: vtab-IN-opt
15:36
Fix the virtual table IN optimizer so that it work even if the virtual table implementation leaves the sqlite3_index_info.aConstraintUsage[].omit flag clear for an equality constraint that it intends to use. check-in: d6e045f8 user: drh tags: vtab-IN-opt
2012-12-13
18:57
Generalize the min/max optimization so that if an appropriate index exists, the index it can be used by any aggregate query that contains only a single max() or min() and does not contain a GROUP BY clause. check-in: 52e75594 user: drh tags: trunk
18:51
Increase the version number to 3.7.16 in advance of adding new features for the next release. check-in: 8bcf5f51 user: drh tags: trunk
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
2012-12-12
14:30
Allow the error message from "PRAGMA integrity_check" to be longer than 20,000 bytes. check-in: 120c82d5 user: drh tags: trunk

2012-12-11
19:40
Update requirements marks and test cases for multi-VALUE INSERT and to fix typos in requirements text. check-in: 81d9ee0f user: drh tags: trunk
19:10
Fix a typo in a comment that is used to generate documentation. No changes to code. check-in: e38adb60 user: drh tags: trunk
2012-12-10
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
2012-12-08
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
2012-12-07

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
09:08
Spelling and header fixes for the async extension. check-in: 930ba852 user: mistachkin tags: trunk

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
19:37
Apply the same restrictions on constant refactoring to statements within a trigger program as top-level statements. Candidate fix for [ae3c5670b6]. Closed-Leaf check-in: 0c31a468 user: dan tags: constant-refactoring-in-triggers
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
04:33
For the sqlite3-all.c target, use backslashes when calling the splitter script via the MSVC makefile. check-in: d507648d user: mistachkin tags: trunk
04:19
Bring the ancient malloc3.test file closer into relevance with the latest core code. check-in: 9793a21c user: mistachkin tags: trunk
02:56
Stop using the TCL_LIBS configuration variable when linking with Tcl. Remove superfluous 'rm' command from the "clean" target. check-in: 15512772 user: drh tags: trunk
01:03
Remove obsolete comments from the definition of the CollSeq object. check-in: 7b695101 user: drh tags: trunk
00:16

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
2012-12-04
11:03
Fix a harmless compiler warning. check-in: 12693deb user: drh tags: trunk

2012-12-03
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
2012-12-01
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
14:26

21:22
Add the SQLLOG capability to trunk. check-in: f0843f88 user: drh tags: trunk
21:12
Improved detection of file-does-not-exist in winDelete. check-in: 92e9b5bc user: drh tags: trunk

2012-11-26
19:50
Add an option to register global hooks used for logging all SQL executed by an application. check-in: cd501bbc user: dan tags: sqllog
2012-11-21
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
2012-11-13
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
2012-11-10
01:27
Merge the latest changes from trunk: chiefly the outer/inner loop query optimizer scoring enhancement and the INSTR() function. check-in: 2993ca20 user: drh tags: sessions
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
17:59
Try to take into account the cost of inner loops when selecting which table of a join to use for the outer loop. check-in: 94255634 user: drh tags: inner-loop-cost

18:41
In test_quota.c, provide a work-around for the missing _chsize_s() function in mingw. check-in: 6b4979e8 user: drh tags: trunk
2012-11-05
16:36
Merge the omit-wal-fix branch into branch-3.7.9 where it belongs, and in so doing get branch-3.7.9 working with SQLITE_OMIT_WAL. check-in: 03919517 user: drh tags: branch-3.7.9
13:51
Add the INSTR() SQL function. check-in: a4c181cb user: drh tags: trunk
2012-11-02
