2013-06-03
14:15
Add test cases to verify that ticket [bc1aea7b725f2761] has been fixed in the NGQP. check-in: 9b97af94 user: drh tags: nextgen-query-plan-exp

12:34
Further improvements to error handling of the run-time loading of SQLite into TCL. check-in: 7cc0c4ee user: drh tags: trunk
2013-05-31
20:43
The NGQP might not find a solution if INDEXED BY constraints on the query are set wrong. If that is the case, print a "no query solution" error and abort before trying to use the non-existant solution. check-in: 42511a7e user: drh tags: nextgen-query-plan-exp
20:28
Do not search using ON clause constraints of LEFT JOINs to the right of the table. check-in: 723f901a user: drh tags: nextgen-query-plan-exp
20:00
Make sure a unique cursor number is allocated for automatic indices. check-in: 433d1aec user: drh tags: nextgen-query-plan-exp
19:14
Do not attempt to generate code in the NGQP if there have been prior errors, since with prior errors some of the expressions might not be fully named resolved. check-in: 665e4291 user: drh tags: nextgen-query-plan-exp
18:20
Fix a problem with code generation on LEFT JOIN of tables without an index. check-in: 0b1bee92 user: drh tags: nextgen-query-plan-exp

Improvements to the ORDER BY suppressor in the NGQP. check-in: 24a2e9dd user: drh tags: nextgen-query-plan-exp
22:27
Incremental check-in with various NGQP fixes. Many tests still fail. check-in: a51d8c92 user: drh tags: nextgen-query-plan-exp
19:29
Futher simplifications to the NGQP. Fix some test cases to use EXPLAIN QUERY PLAN rather than the (now obsolete) sqlite_query_plan global variable. check-in: ae985db4 user: drh tags: nextgen-query-plan-exp
19:28
The expected result in a test case can be of the form "*glob*" or "~*glob*" to match or not match the GLOB pattern. This is useful for matching EXPLAIN QUERY PLAN output that contains regular expression syntax characters like "?", "(", and ")". check-in: a3b4e261 user: drh tags: nextgen-query-plan-exp
17:43
Cut over the NGQP query planner. Remove lots of legacy code. This check-in compiles but does not work. The test suite gets incorrect answers and crashes. check-in: 001539df user: drh tags: nextgen-query-plan-exp
11:48

Add the percentile() SQL function as a loadable extension in the ext/misc directory. check-in: a64d760d user: drh tags: trunk
17:30
Finish removing the sqlite3.inTrans field. In the previous check-in, it was merely commented out because I failed to select File->Save on my text editor. check-in: 2f97e38a user: drh tags: trunk
17:25
Remove the obsolete and unused sqlite3.inTrans field. check-in: c3381cd4 user: drh tags: trunk
12:11
Many small harmless comment changes. Removal of obsolete comments and fixing misspelled words. No changes to code. check-in: a0d5cc93 user: drh tags: trunk
10:52
Merge autoconf-package branch with trunk. check-in: a72f50ef user: dan tags: trunk
2013-05-27

10:11
When writing to an FTS table, take an exclusive shared-cache lock on the %_segdir table before writing. Otherwise, an xCommit() call may report an SQLITE_LOCKED error. check-in: 3cd2da42 user: dan tags: trunk
2013-05-24
14:52
Record in the WhereLoop object the set of virtual table constraints that need not be separately checked. check-in: b49fa745 user: drh tags: nextgen-query-plan-exp
13:55
Merge the latest trunk changes into the NGQP branch. check-in: 7c8f992c user: drh tags: nextgen-query-plan-exp
12:47

Have the "make fulltest" command run the "mmap" permutation test. check-in: 82ad373f user: dan tags: trunk
10:13
Avoid unnecessary calls to FCNTL_SIZE_HINT. Return an error to the user if the file-control invoked by "PRAGMA mmap_size" returns a value other than SQLITE_OK or SQLITE_NOTFOUND. check-in: 40cfde8b user: dan tags: trunk
01:40
Cause the mmap_size PRAGMA to immediately change the mmap space if the database connection is already active. In particular, reducing mmap_size will immediately free up process address space. check-in: 76117792 user: drh tags: trunk
2013-05-22
20:49
Use the NGQP plan for EXPLAIN QUERY PLAN output. This change causes 207 errors in veryquick.test, many of which are benign. check-in: f783e8e6 user: drh tags: nextgen-query-plan-exp
17:01
Allow the rowid at the end of an index to be used in a constraint on that index. check-in: 9bf0524d user: drh tags: nextgen-query-plan-exp
02:06
Improvements to ORDER BY handling in the NGQP. Fix an "exit" mistakenly left in a test script during the previous check-in. check-in: 12c709b4 user: drh tags: nextgen-query-plan-exp
2013-05-21
19:23

20:16
Remove a stray tab character from the transitive_closure extension source code. check-in: 7a9aa21c user: drh tags: trunk
17:15
Fix a bug in SQLITE_TRACE_SIZE_LIMIT that was introduced by check-in [1a1cf5aa86734c8]. That check-in was to remove harmless compiler warnings. So once again, we have introduced a real bug into SQLite by attempting to eliminate a harmless compiler warning. check-in: cec2bcb4 user: drh tags: trunk
16:41
In test file test_syscall.c, include sqliteInt.h before any tcl or system include files. This ensures that the magical defines in sqliteInt.h really do enable large file support (and set things up so that sizeof(off_t)==8). check-in: 0f355bb1 user: dan tags: trunk
12:52
Use sum() instead of total() in mptest/multiwrite01.test too. check-in: d0c2288c user: drh tags: trunk

11:57
In sqlite3_close_v2(), do not attempt to roll back a transaction if there exist active statement objects. Any open transaction will be rolled back when the last of these statement objects is finalized. check-in: d11e7607 user: dan tags: trunk
01:02
Treat identifiers in the HAVING clause the same as in the WHERE clause. Only consider AS names from the result set to match if there are no other matches. Continuation of the fix for [2500cdb9be05]. This check-in fixes a bug found by SqlLogicTest during release testing for version 3.7.17. check-in: 9ffff3d0 user: drh tags: trunk
2013-05-15

17:47
The sqlite3ExprCollSeq() function can no longer be called while parse the schema, so remove the code path inside of sqlite3ExprCollSeq() that dealt with that case. check-in: 867b3e3b user: drh tags: trunk
17:08
Make sure an sqlite3_close() or a rollback on one shared-cache connection does not disrupt the operation of other connections using the same shared cache. Fix for ticket [e636a050b709]. check-in: 5cc1cc55 user: drh tags: trunk
16:24
Extra test for commit [6dae62c4e5]. check-in: b10b9e75 user: dan tags: trunk

15:16
When loading a database schema that contains an index definition that includes a COLLATE clause for which the collation sequence is unavailable, do not assume that that index uses BINARY instead. Fix for [0fc59f908b]. check-in: 6dae62c4 user: dan tags: trunk
13:05
Add the rot13.c loadable extension. check-in: 8f9bd8e7 user: drh tags: trunk
10:21
When closing a connection, avoid tripping active cursors belonging to a different shared-cache client. Also, if sqlite3_close() is called while there are still active statements belonging to the connection, return SQLITE_BUSY and do not roll back any active transaction. Proposed fix for ticket [e636a050b709]. check-in: 6071b7cc user: dan tags: shared-cache-fixes
08:00
Merge updates from trunk. check-in: 6fbad957 user: mistachkin tags: toTypeFuncs

20:36
Avoid deleting a b-tree "has-content" vector belonging to another shared-cache connection from within sqlite3_close(). check-in: 93462df7 user: dan tags: shared-cache-fixes
