Fix harmless compiler warning in FTS5. (check-in: 02448a9f user: mistachkin tags: trunk)
15:58
Provide hints for all terms in a range constraint if there are any equality terms anywhere in the constraint. Range constraint terms are only omitted for a pure range constraint with no equality prefix. (check-in: b5897bc0 user: drh tags: cursor-hints)
12:59
Comment clarification. No changes to code. (check-in: 71a96695 user: drh tags: json)

Add an initial implementation for json_remove(). (check-in: 2a826720 user: drh tags: json)
17:19
Avoid generating hints using constraints that are also used to initialize the cursor, since presumably the cursor already knows about those constraints. (check-in: 142b048a user: drh tags: cursor-hints)
15:17
Initial implementation for json_array_length(), json_extract(), and json_type(). (check-in: 39983204 user: drh tags: json)

Change the display of the P4 operand of CursorHint in EXPLAIN output to function notation. (check-in: bee73d42 user: drh tags: cursor-hints)
2015-08-14
23:57
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)

Duplicate the output of releasetest.tcl into releasetest-out.txt (check-in: 5e06a9c1 user: drh tags: trunk)

2015-08-13

Convert the hint expression of the CursorHint opcode into a string for display by EXPLAIN. (Leaf check-in: 12640cb2 user: drh tags: cursor-hints-displayP4)

Fix a bug in sqlite3ExprContainsSubquery(). (check-in: be254715 user: drh tags: cursor-hints)
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)
13:54
Experimental code (untested) for a JSONB datatype. (check-in: e3596ac7 user: drh tags: json)
11:46
Avoid invoking system call unlink() directly from RBU code. Use the xDelete method of the default VFS instead. (check-in: ee966af8 user: dan tags: trunk)

Add the xPhraseFirst() and xPhraseNext() fts5 APIs, for faster iteration through a single phrases position list. Also optimize xInst() and xInstCount() a bit. (check-in: f7682435 user: dan tags: trunk)
2015-08-11
14:25
Merge fixes from the fts5NoWarn branch. (check-in: 61cb2fc6 user: dan tags: trunk)

Record when an allocated page is taken from the freelist trunk. (check-in: bb5d7782 user: drh tags: experimentalIoLog)

Fix compiler warnings and remove unreachable code. (check-in: fd5608fb user: drh tags: trunk)

2015-08-07

Enhance the query planner so that it is able to use partial indexes that use AND-connected terms in the WHERE clause. (check-in: 06576590 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)

Add tests for the matchinfo-like test function. Fix problems found in test and fts5 code by doing so. (check-in: 9e3aafe4 user: dan tags: trunk)
15:29
Update the spellfix virtual table extension so that an explicit "top = ?" constraint works even if there is also a "distance < ?" or "distance <= ?" constraint. (check-in: 08888383 user: dan tags: trunk)
08:01
Fix some problems in test code detected by cppcheck. (check-in: c9ff4ca4 user: dan tags: trunk)

Remove all references to "docid" within fts5 source code and comments. Replace with "rowid". (check-in: dffd358f user: dan tags: trunk)
2015-08-04
20:29
Add new test file fts5_test_mi.c, containing an implementation of a function similar to FTS4 matchinfo() for FTS5. (check-in: 4f9520a9 user: dan tags: trunk)
19:06
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)

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)
