X-Git-Tag: version-3.47.0~239
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=fe4ed96006fe32ba7fcdb0fdc8bb34e7083a7ebe;p=thirdparty%2Fsqlite.git

Enhancements to covering-index prediction.  In particular, avoid the
false-positive prediction described by
[forum:/forumpost/e60e4c295d22f8ce|forum post e60e4c295d22f8ce].
Add early detection of over-prediction of covering-indexes so that
sqlite3_prepare() will return an error rather than just generate bad
bytecode.
