Subject: Add the sqlite3_index_info.idxFlags field, allowing xBestIndex() implementations... 
X-Git-Tag: version-3.9.0~49
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e60856980a961ff8406df0c9b45529dfecadc863;p=thirdparty%2Fsqlite.git

Add the sqlite3_index_info.idxFlags field, allowing xBestIndex() implementations to specify to SQLite that a strategy may visit at most one row. Add support for this to fts3/4. Omit the statement journal from virtual table UPDATE and DELETE operations that are guaranteed not to affect more than one row.
