19 check-ins using file src/vdbeaux.c version 8b8eeb3c

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
19:37
Provide an #ifdef in shell.c to work around issues when cross-compiling from Ubuntu to windows. check-in: 0a3579d9 user: drh tags: trunk
2014-02-27
15:11
A better way of handling the USE_SYSTEM_SQLITE #define in shell.c. check-in: 51ce713c user: drh tags: trunk
15:04
Add #defines to the command-line shell source code (shell.c) so that it can be imported directly into other projects (ex: Fossil) and used without editing. check-in: a6690400 user: drh tags: trunk
05:47
Merge updates from trunk. check-in: ed0bfcfa user: mistachkin tags: winIoRetry

21:35
More efficient removal of duplicates in recursive queries using the UNION compound operator. check-in: 06c2db87 user: drh tags: trunk
19:05
Only run the OP_OpenRead opcodes for a correlated subquery once, on the initial iteration. Keep the cursor open for subsequent runs. This was suppose to be a performance enhancement, but it is difficult to come up with a query where is makes a significant difference. Hence, the change is getting parked in a branch. Leaf check-in: 3ad687b7 user: drh tags: open-only-once
13:53
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
2014-02-25
21:55
Do not allow temporary registers to be in use across an OP_Yield within a co-routine. Fix for ticket [8c63ff0eca81a9132d8]. check-in: 97a8c973 user: drh tags: trunk
19:38
Make sure temporary registers used within a co-routine are not also used outside of that co-routine, in order to prevent concurrent use of the same register for two different things. Ticket [8c63ff0eca81a9132d8] Closed-Leaf check-in: cc5eda54 user: drh tags: tkt-8c63ff0eca
18:12
Also adjust the order of files in the amalgamation to ensure that _FILE_OFFSET_BITS is defined before any #include, for QNX. check-in: 23001a85 user: drh tags: trunk
14:52
QNX requires that _FILE_OFFSET_BITS be set prior to any system #include. check-in: 953cdd6a user: drh tags: trunk
2014-02-24
21:42
Fix several small style/consistency issues with the previous check-in. check-in: 2477b3a2 user: mistachkin tags: trunk
21:23
Merge updates from trunk. Closed-Leaf check-in: 854d410a user: mistachkin tags: cygDlOpen
21:20
Enhance testing support for the Win32 VFS dynamic extension loading facilities. check-in: 53081e72 user: mistachkin tags: trunk
19:49
Close some stray connections in walro.test. check-in: d6746cab user: dan tags: trunk
19:07
In memsys5, initialize new allocations to non-zero bytes. Change the content of freed allocations to prevent use after free. These changes in SQLITE_DEBUG only. check-in: ba5f0a55 user: drh tags: trunk
14:24
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
