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

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

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

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

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

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].

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
16:08

2013-05-06
21:01
In the command-line shell, output the elements of the schema in the order that they appear in the sqlite_master table. This is necessary in some cases to make the schema parsable. check-in: e5b3cd74 user: drh tags: trunk

Expand scope of the SQLITE_MAX_MMAP_SIZE define for the Win32 VFS. check-in: f4b8faab user: mistachkin tags: trunk
17:03
Refactoring the mmap interface. The controlling pragma is now "mmap_size" instead of "mmap_limit". Also change SQLITE_CONFIG_MMAP_LIMIT and SQLITE_FCNTL_MMAP_LIMIT to SQLITE_CONFIG_MMAP_SIZE and SQLITE_FCNTL_MMAP_SIZE, respecctively. The default mmap_size is now always 0, meaning that memory mapped I/O is off by default. There is a new compile-time option SQLITE_MAX_MMAP_SIZE that determines a hard upper bound on the mmap_size. Setting SQLITE_MAX_MMAP_SIZE to zero disables the memory-mapped I/O logic and causes it to be omitted from the build. An extra argument is added to SQLITE_CONFIG_MMAP_SIZE that can optionally lower the SQLITE_MAX_MMAP_SIZE at start-time. The SQLITE_MAX_MMAP_SIZE is zero for platforms where we know that it does not work, meaning that it cannot be turned on by mistake on those platforms. check-in: ea1404a1 user: drh tags: trunk
