21 check-ins using file src/vdbeInt.h version 8a4d2d69

2013-12-23
11:33
Remove a stray tab character. (check-in: 25b8a1c9 user: drh tags: trunk)
2013-12-22
22:45
Remove a condition that is always in the logic that handles reading default values for columns. (check-in: 895af097 user: drh tags: trunk)
20:44
Make sure the WhereLoop.aLTerm[] array is large enough when processing the skip-scan optimization. Fix for ticket [520070ec7fbaac]. (check-in: 46d04059 user: drh tags: trunk)
2013-12-21
17:14
Fix speedtest1.c so that in --explain mode it only outputs non-explain text for DDL statements. (check-in: 2d2b3c49 user: drh tags: trunk)
17:07
Avoid compiler warnings by only enabling sqlite3ErrName() when SQLITE_TEST is defined. (check-in: 862228e5 user: drh tags: trunk)
16:06
Fix harmless compiler warnings in FTS4. This involved corrupting Martin Porter's beautifully written and elegant stemmer code, making it a little less beautiful and a little less elegant. Today is a sad day. But the warnings from GCC grow increasingly verbose and irksome with each new release and so something had to be done. (check-in: df056798 user: drh tags: trunk)
15:46
Fix the ".echo on" dot-command of the shell so that it echos comments in addition to SQL statements and dot-commands. Add the --explain option to speedtest1 so that the output can be piped into the command-line shell to show nicely-formated VDBE code for the entire test. (check-in: 96397263 user: drh tags: trunk)
00:04
Add a case to speedtest1.c that demonstrates the need to factor OP_Column operators out of inner loops. (check-in: 69a17336 user: drh tags: trunk)
2013-12-20
18:57
Fix compiler harmless warnings in tclsqlite.c that appeared with GCC 4.8.x. (check-in: d93ae683 user: drh tags: trunk)
18:44
Code simplification in sqlite3GenerateIndexKey() by making use of a subroutine found over in expr.c. (check-in: 0026d335 user: drh tags: trunk)
15:59
Combine adjacent single-register OP_Copy instructions into a single multi-register OP_Copy, where possible. Fix the Synopsis comment for multi-register OP_Copy instructions to show the correct register ranges. (check-in: 2ae22dc0 user: drh tags: trunk)
14:48
Allow any arbitrary expression as the filename in an ATTACH statement, including functions and subqueries. (check-in: df70a1f3 user: drh tags: trunk)
13:11
Simplify the accumulator reset for aggregate query processing so that it uses a single multi-register OP_Null rather than a separate OP_Null for each register. (check-in: 2c7fd9b0 user: drh tags: trunk)
2013-12-19
17:04
Do not inject OOM faults into SQLITE_FCNTL_COMMIT_PHASE_TWO file-control invocations. It causes problems for test scripts. (check-in: 8eb28d23 user: dan tags: trunk)
16:26
Make sure errors encountered while initializing extensions such as FTS4 get reported out from sqlite3_open(). This fixes a bug introduced by check-in [9d347f547e7ba9]. Also remove lots of forgotten "breakpoint" commands left in test scripts over the years. (check-in: ca3fdfd4 user: drh tags: trunk)
14:34
Remove an unneeded column-cache flush in aggregate SELECT and an unreachable branch in the INSERT logic. (check-in: ffa092e1 user: drh tags: trunk)
02:56
Omit an unnecessary OP_Null opcode from UPDATE. (check-in: 72d11133 user: drh tags: trunk)
02:23
Omit one or more pointless instructions that occur in between OP_NoConflict and OP_Halt. (check-in: 61e2f357 user: drh tags: trunk)
2013-12-18
18:44
Remove an unnecessary column-cache flush operation. Add code to trace the column cache when compiled with SQLITE_DEBUG and using PRAGMA vdbe_addoptrace=ON. (check-in: 58704ed1 user: drh tags: trunk)
16:27
Remove an unnecessary column-cache flush. Add another test case to the speedtest1.c program to accentuate the benefit of not flushing the cache at that point. (Closed-Leaf check-in: 97fdfc6b user: drh tags: column-cache-debug)
15:11
Show changes to the column cache when PRAGMA vdbe_addoptrace=ON is set. (check-in: 4c6a659c user: drh tags: column-cache-debug)
