* SERVER-46721 Secondary readers should read at the no-overlap time instead of ↵Louis Williams2020-08-062-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lastApplied The no-overlap time, ReadSource::kNoOverlap, is the minimum of replication's lastApplied timestamp and WiredTiger's all_durable time. This time is independent of replication state and ensures queries do not see oplog holes after state transitions from secondary to primary. (cherry picked from commit 25c694f365db0f07a445bd17b6cd5cbf32f5f2f9) (cherry picked from commit 5ddf9db5635e4af2d1295bd2f1007e86d517c6c2) SERVER-44529 Query yield recovery after a stepdown should switch to read at the no-overlap time After yielding and reacquiring locks in a query, the preconditions that were used to select our ReadSource initially need to be checked again. Queries hold an AutoGetCollectionForRead RAII lock for their lifetime, which may select a ReadSource based on state (e.g. replication state). After a query yields its locks, this state may have changed, invalidating our current choice of ReadSource.

* SERVER-48614 Fix plan cache discriminators for partial wildcard indexesDavid Storch2020-06-164-28/+215
| | | | | | | | | | | | | | | | | | Previously, discrimination based on the partial filter expression was done for all paths included in the wildcard projection. This could lead to a situation where two queries were erroneously assigned the same plan cache key. The fix is to ensure that for wildcard indexes, partial index discriminators are instead registered only for those paths mentioned in the partial filter expression. Unlike other kinds of wildcard index discriminators (e.g. handling concerns of null equality or collation), the paths in the partial filter expression are known a priori. Therefore, discrimination based on the partial filter can be done in the same way for wildcard and non-wildcard indexes. (cherry picked from commit 57edf434219c9659354f01fb6bf4f4e6c0370bc4)

* SERVER-42518 Prevent paths with successive array indexes from using a ↵David Storch2019-08-222-50/+119
| | | | | | | | | | | | | | | | | | | | | | | | wildcard index. Consider a query on a generic path "c1.c2...arr.0.1...cn" consisting of n path components. Somewhere in the middle of this path, there is a component "arr" that is known to be multikey, followed by multiple successive array indexes ("0" and "1" in this example). Any predicate whose path matches this description cannot correctly be answered with a wildcard index. This is because wildcard indexes do not recursively expand directly nested arrays. That is, when indexing an array such as [[1, 2], [3, 4]], the index keys will be [1, 2] and [3, 4], as opposed to 1, 2, 3, and 4. Since the index does not contain keys for individual nested array elements, it cannot be cheaply used for queries against nested array elements. This change fixes the planner to avoid attempting to use a wildcard index in such cases, thereby fixing a query correctness bug. (cherry picked from commit 0f0463d0442b2c77cb650a8e84fea4d634fb63e6)
