Introduces a checkShardVersionOKOrThrow_DEPRECATED variant so that we can incrementally fix the places, which are not prepared to catch StaleConfig exceptions.
It uses a memory pool in the execution context to be able to share a
larger memory buffer for multiple KeyStrings.
Added SharedBufferFragment and SharedBufferFragmentBuilder to achieve this.
This redesigns user index build abort to have the following behavior:
- Take a collection X lock to stop the index build from making progress
- If we are no longer primary, return an error
- Check whether we can abort the index build (i.e. it is not already committing
or aborting)
- Delete the index catalog entry and write the abortIndexBuild oplog entry in a WUOW
- Interrupt the index builder thread
- Wait for the thread to exit
- Release locks
- setFilteringMetadata
- getCurrentMetadataIfKnown
- getShardVersionIfKnown
Have been moved from CSS to CSR to ensure no external usages.
Moreover the getShardVersion command is now foribidden on unsharded
mongod. It will return ErrorCodes.NoShardingEnabled in such a
case.
It is meant to be a container for reusing temporary objects within an operation instead of creating and destroying new instances.
At the moment, used for index building where it keeps data structures for KeyStringSet and MultikeyPaths.
