2002-11-10
23:32
Two optimizations to the pager: (1) Write dirty pages back to the database file in order and (2) Keep a separate list of in-memory pages that are in the checkpoint journal in order to speed a checkpoint commit. (CVS 783) (check-in: a6ef6657 user: drh tags: trunk)

Bug fix: When multiple SQL statements were passed into a single sqlite_exec() call, execution speed would decrease for each statement executed because VDBE cursors were not being reused. Now the cursors are reused and execution time is linear. (CVS 754) (check-in: b0d27a37 user: drh tags: trunk)
2002-09-21
15:57
Make sure memory malloced() for structures is aligned on an even byte boundry. Solaris segfaults otherwise. (CVS 753) (check-in: 14ebe30b user: drh tags: trunk)

Rename all tests so that the first part of the test name corresponds to the file that contains that test. This makes it much easier to find a particular test after it fail. (CVS 749) (check-in: 6cb80ae1 user: drh tags: trunk)
2002-09-12

Relax the locking requirements on BTree cursors. Any number of read and write cursors can be open at the same time now, but a write cannot occur as long as one or more read cursors are open.

Before this change, one or more read cursors could be open on a table, or a single write cursor, but not both. Both policies have the same desirable effect: they prevent writes to a table while a sequential scan of that table is underway. But the new policy is a little less restrictive. Both policies prevent an UPDATE from occurring inside a SELECT (which is what we want) but the new policy allows a SELECT to occur inside an UPDATE. (CVS 739) (check-in: 8c2a0836 user: drh tags: trunk)
