Fix more instances of assuming 'char' is signed. And, make sure to never shift a signed integer. Closed-Leaf check-in: f10130ed user: drh tags: broken-on-arm

Do not assume that 'char' is signed. Make it explicit. check-in: 979da752 user: drh tags: broken-on-arm

Refactor the sqlite3VdbeRecordCompare() routine used to compare btree records. Create a couple of fast-track routines to handle the common cases of a string with BINARY collation or integer values as the left-most column. This gives a significant performance boost in common use. Oops: This build does not work on the Beaglebone where "char" defaults to unsigned. check-in: aec5473a user: drh tags: broken-on-arm

Factor the Mem invariant checker into a separate procedure (rather than a macro) so that it can be more easily extended. check-in: 354699d5 user: drh tags: enhanced-mem-check

In the command-line shell add the (undocumented and unsupported) ".eqp" command and -eqp command-line option, to cause EXPLAIN QUERY PLAN to be run on each SQL statement as it is evaluated. Intended use is for analysis of the query planner. check-in: e6ecf733 user: drh tags: trunk

In the command-line shell for CSV import, if the lines are \r\n terminated and the last field is blank, make sure an empty string and not a "\r" string is imported. check-in: 9c2e7612 user: drh tags: trunk
02:26
Improved handling of constants and especially constant functions in the ORDER BY clause of a query. Do not optimize out "ORDER BY random()". Fix for ticket [65bdeb9739605cc2296]. check-in: dca1945a user: drh tags: trunk

QNX requires that _FILE_OFFSET_BITS be set prior to any system #include. check-in: 953cdd6a user: drh tags: trunk

Close some stray connections in walro.test. check-in: d6746cab user: dan tags: trunk

Remove an unused variable from the VDBE_PROFILE compile-time option. Keep the opcode count in an u32 instead of an int. check-in: 4df0ac90 user: drh tags: trunk

Add the VdbeCoverageNeverTaken() macro, and comments that better describe how the VDBE branch coverage measurement works. Add some tags to provide 100% VDBE branch coverage. check-in: c1e94169 user: drh tags: trunk
14:20
Add the SQLITE_NOTNULL P5 code for comparison operations - really a composite of SQLITE_NULLEQ and SQLITE_JUMPIFNULL. This flag indicates that NULL operands are not possible and raises and assert() if NULL operands are seen. Also omit an unnecessary scan of the sqlite_sequence table when writing into an AUTOINCREMENT table. check-in: d2c047f3 user: drh tags: trunk

01:07
Improvements to "NOT IN (SELECT ...)" processing. Only test for NULL values on the RHS on the first iteration, then remember the result. There has been logic to do this for year, but it didn't work right and ended up repeating the NULL test on every iteration. This inefficiency was found using the VDBE coverage testing tools. check-in: 915f6f1c user: drh tags: trunk

Merge in performance enhancements for INSERT operations, especially INSERTs on tables that have no affinity columns or that have many indices or INSERTs with content coming from a SELECT. Add the SQLITE_TESTCTRL_VDBE_COVERAGE test control and the SQLITE_VDBE_COVERAGE compile-time option used for measure coverage of branches in VDBE programs. check-in: a7268769 user: drh tags: trunk
