Pull in all changes from the 3.19.0 release. (check-in: bbd2d0e1 user: drh tags: apple-osx)
18:09
Fix incompatibilities between the "sqldiff --changeset" command and the sessions module. Specifically, allow sessions to process changesets containing tables with zero operations on them and have sqldiff output the expected output for tables with multi-column primary keys. (check-in: 0bb23c48 user: dan tags: trunk)
18:00
Add the ".cd" command to the command-line shell. (check-in: 5fe28e15 user: drh tags: trunk)
17:39
Increase the version number to 3.20 for the next release cycle. (check-in: ab471f61 user: drh tags: trunk)

08:04
Fix a case where NULL was being passed to memcmp() following an OOM. This is probably not a real problem, as the number-of-bytes parameter was passed 0 in this case, but it was causing a santizer complaint. (check-in: 3ea2bad2 user: dan tags: trunk)
08:01
Add code to this branch to emit a log message after each cumulative second that the WRITER lock has been held. (check-in: a726d981 user: dan tags: server-edition)

18:14
Do not save the state of an fts5 merge operation mid-way through an input term, even if no previous entry for that term has caused any output. Doing so may corrupt the FTS index. (check-in: 9a2de4f0 user: dan tags: trunk)
16:49
Cache the JSON parse used by json_extract(). (Closed-Leaf check-in: 44ca6c2c user: drh tags: auxdata-cache)

Negative N values in sqlite3_get_auxdata() and sqlite3_set_auxdata() can be used to access an auxiliary data cache over all functions in a single prepared statement. (check-in: ff530675 user: drh tags: auxdata-cache)
13:43
New requirements marks and documentation for the authorizer. (check-in: 3980ea09 user: drh tags: trunk)

12:05
Change the SQLITE_READ authorization call for unreferenced tables to use an empty string for the column name, as this is less likely to impact legacy authorization callbacks that assume column names are always non-NULL. (check-in: 4139953a user: drh tags: trunk)
2017-05-10
19:42
Rename fields of the internal AuxData object to make them unique and easier to search for. (check-in: 2be9850c user: drh tags: trunk)

Merge the latest enhancements from trunk. (check-in: a7dcf6a7 user: drh tags: schemalint)

17:54
Reuse the same materialization of a view when that view appears in a query more than once, such as in a self-join. (check-in: 9e35c89d user: drh tags: trunk)
16:55
Move terms of the HAVING clause that reference only columns in the GROUP BY clause over to the WHERE clause, resulting in a faster query plan. (check-in: 47cbb471 user: drh tags: trunk)

15:27
Evaluate WHERE clause terms that reference only the index before evaluating terms that require the table, and thereby avoid seeking the table row if index terms are false. This is called the "push-down" optimization in the MySQL world, we are told. (check-in: d7bb79ed user: drh tags: trunk)
14:56
Minor size and performance improvements to the push-down optimization. (Closed-Leaf check-in: 91dfb61a user: drh tags: pushdown-optimization)

2017-04-27
14:12
Do not write master journal filenames into server-mode journal files. Use SQLITE_MUTEX_STATIC_APP1 to protect critical sections in server.c. (check-in: 3144ae40 user: dan tags: server-edition)
13:05
If possible, delete the journal file when a database connection is closed. (check-in: d5b5326d user: dan tags: server-edition)

16:04

2017-04-18
13:50
Use sqlite3_table_column_metadata() instead of a SELECT statement to check for the existence of a %_stat table in fts3. This leads to smaller and easier to test code. (check-in: dc2a4802 user: dan tags: trunk)
11:20
Improved optimizations of views as the right operand of a LEFT JOIN. (check-in: 41c27bc0 user: drh tags: trunk)

18:02
Fix a problem in "PRAGMA foreign_key_check" in handling a WITHOUT ROWID child table with an INTEGER PRIMARY KEY parent key. Also, if an FK violation is detected in a WITHOUT ROWID child table, do not try to read and return the rowid. The second column returned by "PRAGMA foreign_key_check" in this case (WITHOUT ROWID child table) is now always set to NULL. (check-in: 690870bd user: dan tags: trunk)
16:07
Further improvements to test coverage in fts3. (check-in: 352413ee user: dan tags: trunk)

2017-04-16
22:41
In the showwal command-line tool, for unix builds, if the auxiliary argument is of the form "Ntruncate" where "N" is a frame number, then truncate the WAL file after the N-th frame. (check-in: 90015df3 user: drh tags: trunk)
22:08
Add the anycollseq.c loadable extension in etc/misc (check-in: d7b9813c user: drh tags: trunk)

Fix some left-over K&R-C constructs in lemon.c. No changes to the core. (check-in: a5379905 user: drh tags: trunk)
19:03
Add the TK_IF_NULL_ROW opcode to deal with non-NULL result columns in the result set of a view or subquery on the RHS of a LEFT JOIN that gets flattened. (Closed-Leaf check-in: 3a5860d8 user: drh tags: left-join-view)
17:30
When doing a DISTINCT query using an index, try to use the index to skip ahead to the next distinct element, rather than doing a full scan of the index. (This is the "skip-ahead-distinct" optimization.) (check-in: f489b5bb user: drh tags: trunk)
17:18
An initial attempt to optimize VIEWs that occur as the right operand of a LEFT JOIN. This particular check-in does not work correctly because it does not deal with the case of columns in the VIEW that return non-NULL even when all columns in the table of the VIEW are NULL because of the LEFT JOIN. (check-in: 1838a59c user: drh tags: left-join-view)
14:50
Make USE_FULLWARN=1 the default for MSVC and fix harmless compiler warnings. (check-in: 6bf67376 user: mistachkin tags: trunk)
14:02
Enhance the sqlite3TreeView() display for Expr objects so that it shows the iRightJoinTable value for Expr nodes that have the EP_FromJoin property. (check-in: 5159cb8f user: drh tags: trunk)
12:39
Simplify the interface to the subst() routines that are part of the query flattener by collecting common parameters into the SubstContext object and passing around a pointer to that object. (check-in: e651074b user: drh tags: trunk)
12:27
Remove an incorrect ALWAYS(). (check-in: f956f6ae user: drh tags: trunk)

19:48
Simplification of the skip-ahead-distinct logic. There is still an issue with handling COLLATE. (check-in: 57c5173b user: drh tags: skip-ahead-distinct)
18:33
New test cases and minor fixes for the optimization on this branch. (check-in: 70ac9ea1 user: dan tags: skip-ahead-distinct)
15:51

13:01
Only use the skip-ahead-distinct optimization if the index has been analyzed and we know that a skip-head is likely to skip over at least 11 rows. The magic number 11 was determined by experimentation. (check-in: 0cf16dec user: drh tags: skip-ahead-distinct)
09:45
Allow a user column name to be used on the LHS of a MATCH operator in FTS5. (check-in: 6f54ffd1 user: dan tags: trunk)
01:19
Forward port the skip-ahead-distinct branch which was abandoned for some reason that I do not recall. This port should have been achived by a merge of trunk into the previous head of skip-ahead-distinct, but that did not work. So I had to manually "rebase" the changes. (check-in: 132339a1 user: drh tags: skip-ahead-distinct)
00:12
Fix a regression caused by the fix for ticket [6c9b5514077fed34551f98e64c09a1] - control characters allowed in JSON. (check-in: 8e7b6118 user: drh tags: trunk)
2017-04-12
17:50
Update fts5 to support "<colset> : ( <expr> )" for column filtering, as well as "<colset> : NEAR(...)" and "<colset> : <phrase>". (check-in: c847543f user: dan tags: trunk)
17:38
Improved \n and \r escapes in the ext/misc/dbdump.c utility function. The implementation of dbdump.c now matches the implementation in the CLI. (check-in: f2643315 user: drh tags: trunk)

2017-04-04
19:58
Fix a problem causing "PRAGMA integrity_check" to disable the xfer optimization for subsequent VACUUM operations on tables with one or more CHECK constraints. This could result in VACUUM producing slightly larger database files. (check-in: e5bb7db5 user: dan tags: trunk)
2017-04-03
14:07
Avoid an unnecessary call to sqlite3WhereGetMask() inside of whereShortCut(). (check-in: 5c11f430 user: drh tags: trunk)
