* SERVER-31133 Ignore mechanism for `StatusWith`ADAM David Alan Martin2017-12-061-2/+1
| | | | | | | | | Change `StatusWith< T >::getStatus` to return `const Status &&`, which permits an overload for `Status::ignore() const &&`. This would be called from expressions which use `StatusWith< T >::getStatus()` for example, `f().getStatus().ignore()`, giving a straightforward and concicse way to indicate that the success or failure of an operation is irrelevant (and thus the result is also irrelevant).

* SERVER-27244 Status usage compile-time facilities.ADAM David Alan Martin2017-06-181-3/+5
| | | | | | | | | | | | | | | | | There are numerous places in the codebase where `mongo::Status` or `mongo::StatusWith< T >` objects are returned and never checked. Many of these are innocuous, but many of them are potentially severe bugs. This change introduces facilities to permit compile-time warning of unchecked `Status` and `StatusWith` usage on clang compilers. It introduces an `ignore` function which is useful to state that a specific "ignored status" case was intentional. It not presently an error, in clang builds, to forget to check a `Status` -- this will come in a later commit. This also introduces a `transitional_ignore` function, which allows for easy continual auditing of the codebase for current "whitelisted" unchecked-status instances. All present "ignored status" cases have been marked `transitional_ignore`.

* SERVER-22027 Sharding should not retry killed operationsKaloian Manassiev2015-12-301-14/+7
| | | | | | This change introduces a different interruption code (11602) which will be used to kill operations during replication primary stepdown so the config server retry logic can differentiate them from user-killed operations.

| | | | | | This change makes the CSRS config server update operations used by the distributed lock manager and by the metadata updates to retry on NotMaster and network errors.

| | | | | | This change removes all back-off logic from ShardRegistry and CatalogManagerReplicaSet and defers it all to the wait time capability of the ReplicaSetMonitor (through RemoteCommandTargeter).

| | | | | | | | This change makes the cluster 'find' command to retry on a per-host basis instead of the entire operation. Reverts commit c433c8157f988a377c1cf9646078450ecd68c297. Reverts commit 5ab3290f8796f2143acd5011ab0baae70ed5cece.
* SERVER-20646 Move remote cursor host targeting inside the AsyncResultsMergerKaloian Manassiev2015-10-131-42/+90
| | | | | | | No functional changes, just moves the resolution of the remote cursor's host to happen inside the AsyncResultsMerger instead of at the level of the entire find command. Also hooks the async merger tests with the sharding test fixture so they can access all objects.
