|
2013-04-05
| ||
| 20:40 | Improve the code coverage of "permutations.test coverage-pager". (check-in: b095e2cd user: dan tags: trunk) | |

| 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 Otherwise, they may be left holding an out-of-date xFetch page reference.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) | |

| 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) | |

| 12:04 | Add test cases for errors in mmap() or mremap() is os_unix.c. (check-in: 3098a3c1 user: dan tags: experimental-mmap) | |
| 10:29 | Proposed template preprocessor magic for activating mmap only on platforms where we know it works. (check-in: d96272f0 user: drh tags: experimental-mmap) | |
| 01:45 | Reorder two conditions to make coverage testing easier. (check-in: 793ba4e9 user: drh tags: experimental-mmap) | |
| 00:41 | Remove an unreachable condition from pager.c. (check-in: 3628e86b user: drh tags: experimental-mmap) | |
| 00:15 | Always send the SQLITE_FCNTL_MMAP_LIMIT pragma to the VFS, even if the limit is zero and even if the VFS does not support xFetch(). (check-in: 01ffdabb user: drh 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) | |

| 19:53 | Modify various test cases so that they work if the file is extended in units of the system page-size. (check-in: 0e3d5119 user: dan tags: two-mappings) | |
| 19:46 | Increment the version number to 3.7.16.1. (check-in: 7e32eb7b user: drh tags: trunk) | |
| 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) | |

| 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) | |
|
2013-03-26
| ||

| 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) | |

| 18:25 | Simulate OOM errors in the sqlite3OsFetch() function. Run malloc.test as part of the "mmap" permutation. (check-in: 77443ef2 user: dan tags: experimental-mmap) | |
| 17:00 | Change the signature of the xUnfetch method to "int (*xUnfetch)(sqlite3_file*, sqlite3_int64 iOfst, void *p)". (check-in: 115b8305 user: dan tags: experimental-mmap) | |
| 16:28 | Remove unnecessary code to round the size of a memory mapping to 4KB from os_unix.c. Rename SQLITE_IOERR_MREMAP to SQLITE_IOERR_MMAP. Fix other small issues in os_unix.c. (check-in: dce35c01 user: dan tags: experimental-mmap) | |
| 14:31 | Do not return SQLITE_IOERR when the user attempts to open a small file that is not a database with mmap enabled. Instead return SQLITE_NOTADB. (check-in: bbcaab3e user: dan tags: experimental-mmap) | |
| 13:50 | Fix a case in the pager where an xFetch() reference was being leaked following an OOM error. (check-in: 5885ba6c user: dan tags: experimental-mmap) | |
| 12:02 | Add a second test for [38b1ae018f]. (check-in: 5062db67 user: dan tags: trunk) | |
| 11:38 | In fts3, when filtering lists for hits in a specific column, edit the list in place in the same way as it is for NEAR filtering. Fix for [38b1ae018f]. (check-in: f85f9103 user: dan tags: trunk) | |
|
2013-03-24
| ||
| 22:56 | Remove the SQLITE_OMIT_MERGE_SORT compile-time option and its related code. The merge sorter is now a required component. (check-in: 8b44d6fb user: drh tags: trunk) | |
|
2013-03-23
| ||
| 21:00 | Replace the sqlite3_io_methods.xMremap interface with sqlite3_io_methods.xFetch and xUnfetch. (check-in: 1431be95 user: dan tags: experimental-mmap) | |
| 17:29 | Improve a comment in wal.c. No code changes. (check-in: 60b9f5e4 user: dan tags: experimental-mmap) | |
| 14:20 | Fix a case where a checkpoint operation could write to an invalid part of a memory mapped region. (check-in: 8dbe89d0 user: dan tags: experimental-mmap) | |
| 12:15 | In the winMremap VFS function, unmap the region prior to attempting to truncate the file. (check-in: 8870c4cc user: mistachkin tags: experimental-mmap) | |
| 10:09 | Do not unmap the mapped file region in winTruncate as there may be outstanding pointers to it. (check-in: f57a9c91 user: mistachkin tags: experimental-mmap) | |
| 09:56 | Preliminary changes to support the xMremap VFS method on Windows. (check-in: 75a85a1c user: mistachkin tags: experimental-mmap) | |

| 19:17 | Fix a case where the mapped part of a database file may be written during a backup operation. (check-in: c8d67aef user: dan tags: experimental-mmap) | |
| 18:20 | Allow the database file to be memory mapped in wal mode. (check-in: d190ddab user: dan tags: experimental-mmap) | |
| 17:46 | Add a fix for the assert() statements added by the previous commit. (check-in: 19345416 user: dan tags: experimental-mmap) | |
| 08:58 | Add assert statements to os_unix.c to ensure that any mapped region of the database file is not being read or written using the xRead() or xWrite() methods. (check-in: 765615f9 user: dan tags: experimental-mmap) | |
|
2013-03-21
