17:08
Change the interface to sqlite3GenerateConstraintChecks() for improved lucidity and to fix issues in dealing with UPDATEs for WITHOUT ROWID tables. Make sure iDataCur and iIdxCur are initialized when processing DELETEs of a VIEW. UPDATE processing distinguishes between changes to ROWID and PRIMARY KEY. (check-in: c525ac56 user: drh tags: omit-rowid)
14:03
Improved VDBE comments on the constraint checker. Fix a missing write lock in the UPDATE logic. (check-in: 3bed599e user: drh tags: omit-rowid)

11:15
Refactor the INSERT, DELETE, and UPDATE code generators to distinguish between the "data cursor" and the "first index cursor", which are no longer consecutive in the case of a WITHOUT ROWID table. (check-in: 1adfca60 user: drh tags: omit-rowid)
06:39
Update comments in the MSVC batch build tool. (check-in: 0414bb73 user: mistachkin tags: trunk)

15:52
Make sure KeyInfo objects on multi-column indices of WITHOUT ROWID tables have the correct nField and nXField values. Also, add the SQLITE_ENABLE_MODULE_COMMENT compile-time option and the VdbeModuleComment() macro and use it to label entry and exit points of some key routines. (check-in: 6d9af606 user: drh tags: omit-rowid)
13:46
In the P4 column of the EXPLAIN listing, abbreviate "keyinfo" as just "k" and "BINARY" as just "B". (check-in: 72d45eb7 user: drh tags: omit-rowid)
12:43
Enhance the timer in the shell to show wall-clock time in addition to user and kernel CPU time. (check-in: 908e2c21 user: drh tags: trunk)
12:30
Have the shell ".timer on" command cause the shell to report wall-clock time for each query (as well as user and system CPU time). (Leaf check-in: 5530cdc4 user: dan tags: shell-wall-clock)
03:25
Add the "Esri Spatially-Enabled Database" file format to the magic.txt file. (check-in: 8530a18f user: drh tags: trunk)

Import the automatic comment generating changes from trunk. (check-in: 8bb51da1 user: drh tags: omit-rowid)
20:40
Automatically generated comments on many VDBE opcodes when in SQLITE_DEBUG mode. Comments derive from the "Synopsis:" field added to each opcode definition in vdbe.c. (check-in: 5f310c6a user: drh tags: trunk)
16:14
Improved comments on the constraint checking logic. (check-in: 141a38a7 user: drh tags: omit-rowid)

2013-10-26
15:40
Work on the UPDATE and INSERT logic. This is an incremental check-in so that can switch over to trunk to work on an unrelated issue there. (check-in: 086ec2a1 user: drh tags: omit-rowid)
13:36
Replace the OP_IsUnique opcode with OP_NoConflict. This code simplification might be useful to move onto trunk even if this branch is never merged. (check-in: e6650e16 user: drh tags: omit-rowid)
00:58
Minor refactoring of variable names and fixes to comments in insert.c. (check-in: ae61a343 user: drh tags: omit-rowid)

2013-10-24
19:48
Update the interface to the sqlite3GenerateRowDelete() utility so that it is able to handle WITHOUT ROWID tables. The implementation still needs to be completed. (check-in: 85daf517 user: drh tags: omit-rowid)
15:20
Add the ".open" command to the command-line shell. (check-in: 21eccb91 user: drh tags: trunk)

11:55
Remove an obsolete comment from the VDBE. No code changes. (check-in: 53bb070c user: drh tags: omit-rowid)
00:18
Correctly handle queries that use secondary indices of WITHOUT ROWID tables. (check-in: d8bc8595 user: drh tags: omit-rowid)
2013-10-23
23:37
Change the sqlite3OpenTable() utility to open the PRIMARY KEY index when reading a WITHOUT ROWID table. (check-in: 247f3899 user: drh tags: omit-rowid)

2013-10-22
18:01
The Index object now has nKeyCol and nColumn. nColumn is the total number of columns and nKeyCol is the number of key columns. Currently these always differ by one. Refactor aiColumn[] to be of type i16 instead of int. (check-in: a106ce86 user: drh tags: omit-rowid)
14:28
Add a procedure to handle the messy details of allocating an Index object from the heap. (check-in: 45efc94f user: drh tags: omit-rowid)
10:23
Extra backwards-compatibility tests verify that UNIQUE and PRIMARY KEY indices are created in the correct order. Other backwards-compatibility tests already cover this, but it does not hurt to double up. (check-in: 5ca0ea2e user: drh tags: omit-rowid)
01:18
Previous refactor is not going to be helpful because implied indices must be created in the same order that they appear in the CREATE TABLE statement for backwards compatibility. This is a much smaller change to clean up a few loose ends. (check-in: 824b549f user: drh tags: omit-rowid)
2013-10-21

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)
03:53
Make use of xFetch, if it is available when doing a VACUUM or a backup. (check-in: 83bc37af user: drh tags: experimental-mmap)

2013-04-02
20:55
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)

Add test cases to mmap1.test and pagerfault.test. (check-in: 3050136b user: dan tags: experimental-mmap)
18:31
Change an assert in pager.c to acknowledge that it is possible for sqlite3PagerRollback() to return SQLITE_CORRUPT. (check-in: d641d3d2 user: dan tags: experimental-mmap)
18:25
Fix the build for Mac. (check-in: d36ce0bb user: drh tags: experimental-mmap)
15:37
Add new test file btreefault.test. (check-in: 7fe908af user: dan tags: experimental-mmap)
14:37
Fix a faulty assert() in the os_win.c VFS. (check-in: fd6ee549 user: drh tags: experimental-mmap)
13:56
If the SQLITE_TRACE_SIZE_LIMIT compile-time parameter is set to a positive integer then limit the expansion of strings and blobs in trace output to approximately that many bytes. (check-in: e5b71084 user: drh tags: trunk)
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)
18:15
In windows, round down the size of the memory mapped region to the next smaller multiple of the page size. (check-in: 0e44ed1b user: drh tags: experimental-mmap)

Version 3.7.16.1 (check-in: 527231bc user: drh tags: trunk, release, version-3.7.16.1)
2013-03-28
11:40
Adjustment to an extreme corner case in the sqlite3Atoi64() routine. (check-in: 39534b4b user: drh tags: trunk)
2013-03-27
20:41
Fix harmless compiler warnings coming from MSVC64 in test code. No changes to the core. (check-in: 274d2a22 user: drh tags: trunk)
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)
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)
2013-03-26
18:48
Fix a comment in os_unix.c. No code changes. (check-in: 72813b8e user: drh tags: experimental-mmap)
14:36
Change the name of the Pager.pFree field to Pager.pMmapFreelist. (check-in: 611bd824 user: drh tags: experimental-mmap)
14:16
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)
20:30
Use mremap() on Linux. (check-in: 431aecc8 user: dan tags: experimental-mmap)
19:57
Merge all recent trunk changes into the experimental-mmap branch. (check-in: a607d63f user: drh tags: experimental-mmap)
19:05
Add a test that simulates an error in mmap(). (check-in: 6ec7367d user: dan 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)
