16:32
A couple more test cases. (Closed-Leaf check-in: 0ae14217 user: drh tags: tkt-a7b7803e)
16:25
Additional test cases involving the use of a result column specified by its "AS" name as a logical term of the WHERE clause. Ticket [a7b7803e8d1e8699cd]. (check-in: d7cc364e user: drh tags: tkt-a7b7803e)

2012-12-18
19:36
Optimize the degenerate case of a FROM clause table name enclosed all by itself inside parentheses. Generate code as if the parentheses did not exist, rather than the old behavior of manifesting the parenthesized table into a transient table. Also, tag every FROM-clause SELECT subquery that is generated by a parenthesized FROM-clause expression using the SF_NestedFrom flag. The new SF_NestedFrom flag is not yet used for anything. (check-in: 7fecced4 user: drh tags: trunk)
16:07
Resolve names in FROM-clause subqueries prior to resolving names in the result set expressions of a SELECT statement. (check-in: 9b67c633 user: drh tags: trunk)

11:59
On atomic-write capable systems, if copying the contents of an in-memory journal to disk fails, close the (on disk) journal file before returning the error to the caller. This causes the subsequent rollback operation to use the in-memory journal. Fix for [df678d738adb]. (check-in: 8183d8d7 user: dan tags: trunk)
2012-12-17
22:32

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

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)

2012-12-10
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)

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)

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
23:23

23:10
For an ORDER BY on a compound SELECT, take the collating sequence from the left-most term of the compound. (check-in: 8e724b38 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)
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)

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)
05:24
Add a test to ensure that the fix in [b0c1ba655d] has worked. (check-in: 41806de5 user: dan tags: trunk)
05:21
Add a test to ensure that the fix in [b0c1ba655d] has worked. (Closed-Leaf check-in: 59c23394 user: dan tags: mistake)
00:59
