Always provide the BTREE_BULKLOAD hint, even when SQLITE_ENABLE_CURSOR_HINTS is not defined, as that hint gives a 4% performance increase. (check-in: 83a84435 user: drh tags: cursor-hints)
20:08
Updated testing of cursor-hints. Remove the test_cursorhint.c file and associated logic in the core and do tests based purely on the newly enhanced EXPLAIN output. (check-in: bf383e66 user: drh tags: cursor-hints)
18:50
Fix the cursor hint mechanism so that it does the right thing for indexed lookups. (check-in: 581e3d49 user: drh tags: cursor-hints)

20:23
When searching the wal file for a frame, do not search that part that was already checkpointed when the snapshot being read was at the head of the wal file. (check-in: 90760e72 user: dan tags: wal-read-change)
20:07
Merge in all the trunk changes from the previous year. This breaks the cursor-hint mechanism, but provides a baseline for trouble-shooting. (check-in: 82a7a61b user: drh tags: cursor-hints)
18:26
Add the sqlite3rbu_savestate() function to the rbu extension. To force rbu to save its state to disk without closing the sqlite3rbu* handle. (check-in: 851a875a user: dan tags: trunk)

16:49
Begin adding an extension that provides JSON SQL functions. (check-in: dde8afdd user: drh tags: json)
15:36
Minor optimization for fts5 API xInst(). (check-in: efb7c9c5 user: dan tags: trunk)
12:11

Record when an allocated page is taken from the freelist trunk. (check-in: bb5d7782 user: drh tags: experimentalIoLog)
20:22
Add the sqlite3_experimental_log_open() interface. This is for diagnostic use only and is not intended to ever go on trunk. (check-in: ac5d2e9d user: drh tags: experimentalIoLog)
2015-08-08
23:30
Fix compiler warnings and remove unreachable code. (check-in: fd5608fb user: drh tags: trunk)

20:06
Add a specially formatted comment to shell.c to make it easier for scripts to edit. No code changes. (check-in: 6d47b35a user: dan tags: trunk)
09:42
Within a write-transaction on a wal database in mmap mode, check the page-cache for an entry before the wal file. This can be faster if the wal file is very large. (Leaf check-in: 3a82c8e6 user: dan tags: mmap-wal-bigtrans)
2015-08-06
12:54
increase the version number to 3.8.12 (check-in: e596a6b6 user: drh tags: trunk)

Improve the usage comment on sqlite3_analyzer: show the available switches. (check-in: 783f78e3 user: drh tags: trunk)
15:29
Update the [showdb] program so that the database file is read directly (bypassing the SQLite VFS) only if the --raw option is specified. Otherwise, it is read using the default VFS. Also, the URI syntax may be used on the command line to specify the name of the database file to examine, so an alternative VFS may be requested using a URI parameter. (check-in: e3c6d4b6 user: dan tags: trunk)
15:23
Update the [showdb] program so that the database file is read directly (bypassing the SQLite VFS) only if the --raw option is specified. Otherwise, it is read using the default VFS. An alternative VFS may be specified by specifying the database file to open using the URI syntax. (Closed-Leaf check-in: 9699e9bd user: dan tags: showdb-uri-option)
14:18
In the sqlite3_analyzer.exe utility, show the depth of each btree and report the average fanout of indexes and WITHOUT ROWID tables. (check-in: cd997770 user: drh tags: trunk)
2015-08-03
17:03
Add the "--uri" option to utility program "showdb". This option causes showdb to use sqlite with the SQLITE_OPEN_URI option to open the database file, instead of opening it directly using the OS open() function. (check-in: 90e34d51 user: dan tags: showdb-uri-option)
13:44
Allow a VIEW to reference undefined tables and functions when initially created. The error report is deferred until the VIEW is used. This allows views to be created before subviews and tables that the view references. (check-in: 70b57daf user: drh tags: trunk)
2015-08-01
18:18
Add extra tests for RBU and FTS3/4. (check-in: 34190449 user: dan tags: trunk)

17:48
Remove a duplicate "typedef struct Fts5Global Fts5Global;" from fts5_main.c (duplicate is in fts5Int.h). (check-in: 54a771fe user: dan tags: trunk)
15:14
When building the VSIX package for UAP, omit the AppLocal suffix for the MSVC runtime library because it is no longer needed. (check-in: fee7ad73 user: mistachkin tags: trunk)
15:13
Fix a problem causing [sqldiff --rbu] to fail on tables for which all columns are part of the PRIMARY KEY. (check-in: 93449e70 user: dan tags: trunk)
14:43
Fix a bug in the fts5 porter tokenizer preventing it from passing xCreate() arguments through to its parent tokenizer. (check-in: c3c672af user: dan tags: trunk)
2015-07-30
20:26
Add the --rbu switch to the "sqldiff" utility. (check-in: 098bea26 user: dan tags: trunk)
11:38
Allow RBU tables to be named "data[0-9]*_<target>" instead of strictly "data_<target>". Also update RBU so that it always processes data tables in order sorted by name. (check-in: 287aa306 user: dan tags: trunk)
11:26
Return an error message (instead of segfaulting) if test function fts5_expr() is invoked with no arguments. (check-in: 8e818b89 user: dan tags: trunk)
2015-07-29
22:38
Support building VSIX packages for UAP using Visual Studio 2015 and the Windows 10 SDK. (check-in: 96559adb user: mistachkin tags: trunk)
22:37
Update Windows 10 SDK version for RTM. (Closed-Leaf check-in: 80ab338c user: mistachkin tags: msvc2015)
21:47
Add SQLITE_DISABLE_INTRINSIC define to disable use of intrinsic functions (e.g. for certain older compilers and/or platforms). (check-in: f0075d73 user: mistachkin tags: trunk)
20:24
Fix the releasetest.tcl script so that it ignore cast overflow errors that recent versions of clang generate but which are unavoidable given the test input. (check-in: a0020c57 user: drh tags: trunk)
20:00
Version 3.8.11.1 (check-in: cf538e27 user: drh tags: trunk, release, version-3.8.11.1)
15:22
Restore an undocumented side-effect of PRAGMA cache_size: it forces the database schema to be parsed. Also increase the version number to 3.8.11.1. (check-in: e4628de3 user: drh tags: trunk)
14:58
Update comments in fts5.h describing the xColumnCount() API function. (check-in: a623eb55 user: dan tags: trunk)
14:46
Increase the version number to 3.8.11.1 (Closed-Leaf check-in: 326d746d user: drh tags: branch-3.8.11)
14:10
The "PRAGMA cache_size" reads the database schema, as it has done in all prior versions of SQLite. This side-effect of cache_size is undocumented, but apparently it does get used and its absence from 3.8.11 was causing problems. (check-in: 4489722a user: drh tags: branch-3.8.11)
12:14
Only allow UNLOCKED transactions to commit if none of the pages read by the transaction have been modified since it was opened. (check-in: 0b971842 user: dan tags: begin-concurrent)
2015-07-28
19:35

Enhance the pcache1 page cache so that it tries to allocate a block of SQLITE_DEFAULT_PCACHE_INITSZ pages from malloc() on startup, and uses those preallocated pages when possible rather than going to malloc() for each individual page.
