In an ORDER BY LIMIT, make sure the ORDER BY expression evaluator does not try to reuse values from the result set if the result set has not yet be computed. This fixes a bug in the recent deferred-row loading optimization, check-in [c381f0ea57002a264fd958b28e]. OSSFuzz discovered the problem. check-in: 5d61e75f user: drh tags: trunk

In ORDER BY LIMIT queries, try to evaluate the ORDER BY terms first, and it it becomes clear that the row will not come in under the LIMIT, then skip evaluation of the other columns. check-in: c381f0ea user: drh tags: trunk
22:52
Fix a branch that has become unreachable due to recent enhancements. check-in: 81ab5e0d user: drh tags: trunk

Improved security for VACUUM. This check-in combines the fixes of [ab0d99d0b5ede] and [27754b74ddf646] in a way that is less likely to to be broken by future changes. check-in: 260fc696 user: drh tags: trunk
