| | | | | | Addresses the case where a time zone expression lives within a collection validator as part of a $expr expression. In this case, the Expression will outlive the OperationContext it was created under.

| | | | | | | | If a field renamed by $project or $addFields is used in a subsequent $match, we can now swap the $match and update it to use the original (or, "renamed from") field name. This allows $match planning to result in better index usage in some cases.

* SERVER-25535 Remove injectExpressionContext().Charlie Swanson2016-12-161-92/+336
| | | | | | | | | | | | | | | These methods were formally used to propagate a new ExpressionContext to stages, accumulators, or expressions which potentially needed to comparisons. Originally, this was necessary since Pipeline parsing happened outside of the collection lock and thus could not determine if there was a default collation on the collection. This meant that the collation could change after parsing and any operators that might compare strings would need to know about it. We have since moved parsing within the lock, so the collation can be known at parse time and the ExpressionContext should not change. This patch requires an ExpressionContext at construction time, and disallows changing the collation on an ExpressionContext.
