* SERVER-40429 Add merge stage to write output to existing collectionAnton Korshunov2019-05-021-10/+10

* SERVER-40476 remove mongoutils::strBilly Donahue2019-04-091-1/+1
| | | | | | Rename utils/mongoutils/str.h => utils/str.h Rename namespace mongoutils::str => str Rename mongo::strcasecmp => str::caseInsensitiveCompare.
* SERVER-38360 Prevent $out writing to ns read from in the same pipelineCharlie Swanson2019-02-141-5/+23
| | | | | This restriction only applies to $out with modes "insertDocuments" and "replaceDocuments".
* SERVER-39560 - remove leading blank line on all C++ filesBilly Donahue2019-02-131-1/+0
| | | | | | Remove leading comments that are just stating the filename. Move any file-level comments below the copyright banner. Remove leading blank lines.
* SERVER-38311 Change out merging strategyCharlie Swanson2019-02-131-2/+1
| | | | | Allows an $out stage to run in parallel on all shards if the target collection is sharded and so is the input collection to the aggregate.
* Revert " SERVER-38311 Adjust $out merging strategy"Charlie Swanson2019-01-161-1/+2

* SERVER-35419 $lookup and $facet must inherit constraints from childrenKyle Suarez2018-09-141-6/+6
| | | | | | | | By default, $lookup and $facet do not write persistent data and are allowed in a transaction. However, both stages must inherit the "strictest" disk use requirement of any stage in their sub-pipelines, and can only be used in a transaction if each of those pipelines contain only transaction-compatible stages.
* SERVER-35905 Add logic to detect when $out is eligible for an exchangeCharlie Swanson2018-08-241-0/+42

* SERVER-33323 Refactor agg cursor merging on mongosCharlie Swanson2018-08-151-22/+3
| | | | | | | | | | This commit makes it so that aggregations will always use a $mergeCursors as a wrapper around a AsyncResultsMerger, which is new behavior for mongos. As part of this refactor, we can delete the concept of a 'merging presorted' $sort stage (which is now handled by the AsyncResultsMerger) and delete the DocumentSourceRouterAdapter stage which talked to a RouterStageMerge, instead directly using a $mergeCursors stage.

* SERVER-35043, SERVER-22949: move geoNear implementation into aggregationKyle Suarez2018-06-181-9/+10
| | | | | | | | | | This commit removes the geoNear command and moves its implementation into the aggregation framework. Users should use the aggregate command with a $geoNear stage. The implementation rewrite additionally removes the limit in the $geoNear aggregation stage. To limit the number of results, use a $limit stage.

* SERVER-33323 Fix pushBack, remove const from size_t, and fix s390xCharlie Swanson2018-04-051-1/+3
| | | | | | | | | | Check if the pipeline is empty before setting the new stage to point to the last one in Pipeline::pushBack(). Remove unnecessary const qualifier from std::size_t return types. Work around a compiler bug on s390x by allowing a CursorResponse to be copied.

* SERVER-25694 Eliminate race in PlanExecutor cleanup.Charlie Swanson2017-04-131-8/+49
| | | | | | | | | | | Ensures that a collection lock is held in at least MODE_IS while deregistering a PlanExecutor from the cursor manager. Introduces new PlanExecutor::dispose() and ClientCursor::dispose() methods that must be called before destruction of those classes, and ensures they are called before destruction. These calls will thread an OperationContext all the way through to DocumentSource::dispose() for each stage in a Pipeline, which will give DocumentSourceCursor a chance to acquire locks and deregister its PlanExecutor if necessary.
