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

18:06
Increase the default SQLITE_MAX_SCHEMA_RETRY to 50. Make sure that macro covers every case where a prepared statement might need to be reprepared due to a schema change. The sqlite3_exec() interface now uses sqlite3_prepare_v2(). check-in: c1d7304c user: drh tags: trunk

Fix a bug in the detection of iOS when setting the default mmap_limit. check-in: ac1432b3 user: drh tags: experimental-mmap
13:09
Change the mmap_limit pragma to report the new limit, or to report the existing limit if called with no arguments. Report the default mmap_limit as part of PRAGMA compile_options. Set the default mmmap_limit to 0 for all systems other than linux, mac, windows, and solaris. check-in: 2d9f1327 user: drh tags: experimental-mmap
11:52
Remove the restriction on using xFetch to load the root pages of tables and indexes. It appears to have been based on a misconception. check-in: 5b082efe user: dan tags: experimental-mmap
11:38
When moving a page to make way for the root page of a new table or index in an auto-vacuum database, save the positions of any cursors that may be holding xFetch references to the page being moved. check-in: 9d9b1da5 user: dan tags: experimental-mmap
11:17
In btree.c, save the positions of other cursors open on the same table when writing via an incremental blob handle. Otherwise, they may be left holding an out-of-date xFetch page reference. check-in: 3f09fba1 user: dan tags: experimental-mmap
10:50
Initialize the mmap_limit of temporary files to the configured mmap_limit. check-in: 24bab759 user: drh tags: experimental-mmap

Fix a resource leak in os_unix.c. check-in: b29cda03 user: dan tags: experimental-mmap
20:29
Adjustments to mmap1.test so that it works better on windows. It still gets some answers wrong, but it no longer crashes. check-in: ee8d3cee user: drh tags: experimental-mmap
20:19
Fix a bug in mmap2.test that was leaving an invalid sqlite3_log() callback installed, causing a crash. check-in: c0cdaa07 user: dan tags: experimental-mmap

2013-04-01
22:42
Remove a debugging printf() accidently left in the previous check-in. check-in: 8198cdd8 user: drh tags: experimental-mmap
22:38
Add the SQLITE_CONFIG_MMAP_LIMIT configuration option for overriding the SQLITE_DEFAULT_MMAP_LIMIT compile-time setting. Enhance "PRAGMA mmap_limit" so that without a specific database name, it sets the limit on all database files and changes the default for any future databases that might be added using ATTACH. check-in: 78141d0a user: drh tags: experimental-mmap
18:25
Add a comment to xUnfetch on windows to say that the call to winUnmapfile() might be unnecessary. check-in: e3c63c31 user: drh tags: experimental-mmap

17:20
In order to optimize out the ORDER BY clause, outer loops must generate values for ORDER BY terms that are unique or else the inner loops must generate no more than a single row. Fix for ticket [a179fe7465]. check-in: 2936f746 user: drh tags: trunk
16:42
Restore additional ORDER BY optimizations that where broken by the recent ORDER BY fix. Closed-Leaf check-in: c77ee6e2 user: drh tags: orderby-fix
16:05
Improved optimization of ORDER BY. check-in: 97e5c70f user: drh tags: orderby-fix
15:04
A fix and test-case for the ORDER BY problem identified by ticket [a179fe7465]. This change causes sorting to occur in some cases where it is not strictly necessary. Further work is needed to avoid those extra sorts. check-in: 488089e6 user: drh tags: orderby-fix
03:15
Candidate fix for ticket [6bfb98dfc0c]: Make sure invalid cursors drop all references to database pages prior to doing any insert or update. check-in: 322a5f08 user: drh tags: trunk

In btree.c, save the positions of any open cursors before moving any pages around to auto-vacuum the database on commit. check-in: 30c0a693 user: dan tags: experimental-mmap
01:07
Previous check-in accidently left mmap turned off by default. This checkin fixes that. Unfortunately, shared.test is now segfaulting. All other veryquick tests appear to work, however. check-in: a850c731 user: drh tags: experimental-mmap
2013-03-25
23:09
Memory-mapped I/O is now on by default. The "PRAGMA mmap_limit(N)" can be used to issue a hint to the VFS to limit mmap space to N bytes. The VFS is free to ignore that hint if desired. However, if "PRAGMA mmap_limit(0)" is used, xFetch is never called. check-in: 1b37c4ef user: drh tags: experimental-mmap
20:50
Add munmap and mremap to the set of os interfaces that can be overloaded in os_unix.c. check-in: 8776047b user: drh tags: experimental-mmap
