| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Segregate old-style dbtests into their own Suite initialization system: OldStyleSuiteSpecification. This is where the funky deprecated features can live on without interfering with the Suite API. It also gives us a searchable base class to identify them in the future. OldStyleSuite has `setupTests()` and an `add<T>()` that Suite does not have. Suite API can shrink when it doesn't have to support these dbtest adaptor features. Suite only needs non-template `add(name, callback)`. - Add OldStyleSuiteInitializer to some dbtests that were missing it! These didn't use SuiteInstance to register themselves and were incorrect. They would self register, resulting in _allSuites() holding a std::shared_ptr to a static-duration Suite object! - Change `getSuite()` to return `Suite&` instead of `Suite*`. - No more "self-registering" in Suite constructor. Registration must be done as a separate post-construction step. This removes some unusual lifetime management code and is easier to document. Suite::getSuite(name) is the only way to make a Suite, and it does the make_shared and registration calls with a pseudo-private ConstructorEnable idiom. - Suite->run() returns std::unique_ptr<Result> instead of raw `Result*`. It's virtual to support OldStyleSuite behavior. - Suite._ran does nothing. Removed. - Result.cur does nothing. Removed. - Switch to pass-by-value and std::move for most ctor args. - Add explicit on 1-arg ctors. - Get rid of TestHolder. It's just a 2-field struct. - use fmt instead of snprintf - TEST and TEST_F macros: generate TEST_TYPE once. - TEST and TEST_F macros: inline the _agent variable. - Mark _doRun as `override`. - Terminology: replace CASE_NAME with SUITE_NAME. - rename DeathTestImpl -> DeathTestBase - move getDeathTestPattern into the test as a static member function - refactor out some repetition from the comparator decl macros - use if-constexpr and diamond relops to clean up the ComparisonAssertion class. - dbtests: conditionally skip some add<T> calls - further dedup (DEATH_)TEST(_F) macros
* SERVER-42302 Move Document/Value library to db/exec/document_value directory.David Storch2019-10-011-2/+2
| | | | | | Document/Value is now used throughout the query execution engine, and therefore should move into the directory which holds query execution code.

* SERVER-40056 Remove partial implementation of streaming $group.David Storch2019-03-111-310/+0
| | | | | | The streaming $group optimization was never fully implemented, so the code was disabled. This patch removes the dead code, including DocumentSource::getOutputSorts().
* 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 Swanson2019-02-131-7/+6
| | | | | 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.

* SERVER-33323 Refactor agg cursor merging on mongosCharlie Swanson2018-08-151-4/+5
| | | | | | | | | | 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-34798 Remove ServiceContext subclasses and use new ServiceContext in ↵Andy Schwerin2018-06-221-22/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | every unit test. This patch does several loosely related and surprisingly hard to separate things. 1.) Make the ServiceContext class final 2.) Create a mechanism, called ConstructorActions, for running methods on ServiceContexts immediately after they're built and immediately before they're destroyed. 3.) Introduce / improve test fixture base classes for tests, giving them fresh ServiceContext instances for each test case. There is one fixture for tests that need a storage engine and another for those that do not. 4.) Make several remaining global variables SC decorations in support of (3) 5.) Replace many MONGO_INITIALIZERS that access getGlobalServiceContext with the new constructor-actions system, which is needed for (3.) 6.) Fix up tests to use the fixtures from (3) and fix tests that silently used different service contexts in together in a technically illegal fashion that now breaks. 7.) Utilize (2) as necessary to simplify initialization of new ServiceContexts, simplifying the fixtures in (3).

* SERVER-35043, SERVER-22949: move geoNear implementation into aggregationKyle Suarez2018-06-181-1/+1
| | | | | | | | | | 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-28651 Move agg var ownership to ExpressionContextJames Wahlin2017-04-291-10/+7
|
* SERVER-25535 Remove injectExpressionContext().Charlie Swanson2016-12-161-13/+13
| | | | | | | | | | | | | | | 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.
