Fix corner cases involving corrupt varint values in record headers. (Closed-Leaf check-in: 3189116b42 user: drh tags: btree-opt)
18:24
Performance improvements in btreeParseCell() by inlining the varint decoder. (check-in: faab0ed928 user: drh tags: btree-opt)
17:19
Add the MemPage.xParseCell method and provide various implementations (variations on the former btreeParseCellPtr()) depending on the page type. (check-in: 41d03d883c user: drh tags: trunk)
15:07
Make cellSizePtr() a method on the MemPage object, with alternative implementations depending on the page type. This results is a small performance improvement and size reduction. (check-in: 02f7e9d7d7 user: drh tags: trunk)

15:26
Further #ifdef changes in speedtest1.c in order to support SQLite back to version 3.3.9 and perhaps even earlier. (check-in: 9246eca54a user: drh tags: trunk)
14:32
Pervent the likelihood() function from moving ON clause terms of a LEFT JOIN into the WHERE clause. Fix for ticket [5f60b11fc8e23490e2] (check-in: ed96e14adc user: drh tags: trunk)
14:09
Show the values of Expr.flag in the AST of ".selecttrace" (check-in: a84d1004cb user: drh tags: trunk)
12:37
Add #ifdefs to some features speedtest1.c so that it compiles with older versions of SQLite, going back to version 3.5.1. (check-in: f50dd154d3 user: drh tags: trunk)
2015-06-17
23:28
Performance improvement in sqlite3VdbeMemShallowCopy() for the common case where the receiver does not require prior resource deallocation. (check-in: d718ea36dc user: drh tags: trunk)
19:06
Use 'binary' mode for popen with MSVC. (Closed-Leaf check-in: 7b84641e55 user: mistachkin tags: popenMsvc)
