Minor performance tuning of the NGQP. check-in: cbef38c2 user: drh tags: nextgen-query-plan-exp
16:17
Up until now the fts4 "unicode61" tokenizer has treated all private use codepoints except the first and last of each of the three ranges as alphanumeric (eligible to be part of tokens). This commit fixes this so that all private use codepoints are considered alphanumeric. In other words, it fixes the handling of codepoints 0xE000, 0xF8FF, 0xF0000, 0xFFFFD, 0x100000 and 0x10FFFD. check-in: 6cfd9af5 user: dan tags: trunk

Adjust the xBestIndex methods on both the fuzzer and transitive_closure virtual tables so that an unused MATCH operator gets a really large cost. Remove ambiguities from the fuzzer test cases. check-in: e2c1af78 user: drh tags: nextgen-query-plan-exp

Set the WHERE_UNIQUE flag on loops that can only run once. check-in: 510f4d8e user: drh tags: nextgen-query-plan-exp

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

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

17:25
Remove the obsolete and unused sqlite3.inTrans field. check-in: c3381cd4 user: drh 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

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

17:15
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
