Subject: Btree interface refactoring:
X-Git-Tag: version-3.14.0~110
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5cd22006ef417a954b3e57aed12c4ebb087a5e40;p=thirdparty%2Fsqlite.git

Btree interface refactoring:
(1) The sqlite3BtreeKeySize() interface is renamed to sqlite3BtreeIntegerKey()
and modified to work only for table btrees with a rowid.
(2) The sqlite3BtreeDataSize() interface is renamed to sqlite3BtreePayloadSize()
and modified to work with any btree.
(3) The sqlite3BtreeDataFetch() and sqlite3BtreeKeyFetch() routines are
combined into a single sqlite3BtreePayloadFetch() routine.
The result of these changes is a smaller binary and fewer CPU cycles needed
to run queries.
