* SERVER-37560 Allow change streams to work with speculative majority readsWilliam Schultz2018-12-211-2/+4
| | | | This patch allows change stream queries to use speculative majority reads so that they can be used even when enableMajorityReadConcern:false. Change stream aggregation commands are allowed to use speculative majority reads as well as 'find' commands that specify a special flag. This commit also enables all change streams tests and suites on the enableMajorityReadConcern:false Evergreen variant. No optimizations for speculative majority change streams are included in this commit.
* SERVER-37560 Add API for allowing commands to support speculative majority readsWilliam Schultz2018-11-141-0/+5
| | | | This patch lays the groundwork for allowing read queries to take advantage of "speculative" majority reads, which is a mechanism for satisfying majority read guarantees without storage engine support for reading from a historical snapshot. This patch adds a flag on the ReadConcernArgs object to indicate whether a query should use the speculative behavior, and it also adds a method to the CommandInvocation interface that allows commands to optionally support speculative majority reads. The intention is to initially only utilize this behavior for change stream queries i.e. 'aggregate' and 'find' commands, but the feature is, in theory, generic.

* SERVER-34628 Really remove appendCommandStatusMathias Stearn2018-05-081-7/+3
| | | | | | | | | | All remaining callers are transitioned to some form of usassert. This was done with an elaborate set of vim macros to make this tractable. Therefore it should not be considered an example of the best way to write new code, just as an improvement on what was there before. In particular, I couldn't easily remove Status's that are named then only used once in uassertStatusOK, nor could I convert the pattern of checking a StatusWith<T>'s getStatus() then calling getValue() to just call uassertStatusOK(returnsStatusWith()).

* SERVER-19758 add support for "executionStats" and "allPlansExecution" to agg ↵David Storch2017-03-131-499/+40
| | | | | | | | | | | | | | | | | explain Like other explainable commands, aggregate can now be explained using the explain command, e.g. db.runCommand({explain: {aggregate: ...}, verbosity: "executionStats"}). The existing explain:true flag corresponds to "queryPlanner" mode and is still supported. However, explain:true cannot be specified when explaining aggregate via the explain command. Additional execution information is provided only in the $cursor section of the aggregation explain output. Having aggregation stages themselves track and report execution info is further work.

* SERVER-25535 Remove injectExpressionContext().Charlie Swanson2016-12-161-22/+22
| | | | | | | | | | | | | | | 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.

* SERVER-27065 cleanup ClientCursor, ClientCursorPin, and CursorManagerDavid Storch2016-12-021-20/+18
| | | | | | | | | | | - Makes cursors come into existence pinned. This fixes a race condition in which a cursor could time out in between being constructed/retrieved and being pinned. - Reduces the public interface of ClientCursor. In particular, makes ClientCursor's constructor and destructor private. - Cleans up header file comments in order to more clearly indicate expected usage.
* SERVER-25038 add LiteParsedPipelineDavid Storch2016-10-031-40/+23
| | | | | | This provides a way to do pre-parse validity checks. Full parsing of the Pipeline must be done under the collection lock, when the collation is known.
* SERVER-25969 make slaves and secondaries always use BSON 1.1 validationDavid Storch2016-09-201-2/+2
