12:41
Further minor enhancement and size reduction in sqlite3ExprAssignVarNumber(). check-in: eacfdcf2 user: drh tags: trunk
03:52
Performance optimization in sqlite3ExprAssignVarNumber(). check-in: 5987ca1f user: drh tags: trunk
2017-01-30
11:38
Fix building with SQLITE_OMIT_FOREIGN_KEY defined. check-in: e93d2c49 user: dan tags: trunk
2017-01-28
20:46
In the amalgamation, allocate the parser engine object from stack rather than from heap, for improved performance. This only happens in the amalgamation, since otherwise the sqlite3RunParser() routine does not know the object size. check-in: 4fe879d4 user: drh tags: trunk
19:53
Fix a couple comment typos. No changes to code. check-in: 2a2e7d86 user: mistachkin tags: trunk
19:45
Avoid redundant table b-tree cursor seeks in UPDATE statements that use the two-pass strategy. check-in: dc555b10 user: dan tags: trunk
15:26
Updates to the sqlite3_blob documentation. No changes to code. check-in: 426b440a user: drh tags: trunk
13:40
In the speed-check.sh script, automatically invoke "fossil test-diff --tk" on the cachegrind output against trunk, if not generating a trunk run. check-in: aa1ab371 user: drh tags: trunk
06:50
Fix a typo in the docs for sqlite3_update_hook(). check-in: 7c029655 user: dan tags: trunk
2017-01-27
19:27
Add the sha1.c loadable extension that implements the sha1() and sha1_query() SQL functions. check-in: 24e77c1c user: drh tags: trunk
17:02
Fix a problem causing the pre-update hook to be invoked by DROP TABLE statements. check-in: fbb6bf1b user: dan tags: trunk
13:14
Alternative ICU fix (compare to check-in [50e60cb4]) that avoids casting integers to pointers. check-in: d9752c8f user: drh tags: trunk
01:52
In the command-line shell, enhance the ".mode" command so that it restores the default column and row separators for modes "line", "list", "column", and "tcl". check-in: 58f02e6e user: drh tags: trunk
01:25
Another micro-optimization in accessPayload(). Slightly smaller and faster. check-in: c012619b user: drh tags: trunk
01:13
Performance optimization in accessPayload(). check-in: ebb1fd98 user: drh tags: trunk
00:31
Simplify the accessPayload() routine so that it always populates the overflow page cache. In the one case where populating the page cache can lead to problems, simply invalidate the cache as soon as accessPayload() returns. This simplification reduces code size and helps accessPayload() to run a little faster. This backs out the eOp==2 mode of accessPayload() added by check-in [da59198505]. check-in: 68e7a8c6 user: drh tags: trunk
2017-01-26
21:30
Remove an unreachable branch in the error handling logic for sqlite3BtreePayloadChecked(). check-in: 293bf3ed user: drh tags: trunk
18:00
Improvement to the OP_Permutation opcode to prevent it from using CPU cycles for initialization in prepared statements that do not use that opcode. check-in: b4a98f65 user: drh tags: trunk
