| 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].

| 23:40 | Combine the various boolean fields of the BtCursor object into a single bit-vector. This allows setting or clearing more than one boolean at a time and makes the overflow-pgno-cache branch faster than trunk on speedtest1. (check-in: 968fec44d7 user: drh tags: overflow-pgno-cache) | |
