2020-07-28Implemented multihost database (#9556)Stelios Fragkakis
* Hard code a node for non-legacy multidb test Skip dbengine initialization for new incoming children Add code to switch to multidb ctx when accessing the dbengine * When a non-legacy streaming connection is detected, use the multidb metadata log context * Clear the superblock memory to avoid random data written in the metadata log * Activate the host detection during compaction Activate the host detection during metadata log chart updates Keep the host in the user object during replay of the HOST command * Add defaults for health / rrdpush on HOST metadata replay Check for legacy status on host creation by checking is_archived and if not conclusive, call is_legacy_child() Use defaults from the stream.conf * Count hosts only if not archived When host switches from archived to active update rrd_hosts_available Remove archived hosts from charts and info * Change parameter from "multidb disk space" to "dbengine multihost disk space" Remove unused variables Fix compilation error when dbengine is disabled Fix condition for machine_guid directory creation under cache_dir * Enable multidb disk space file creation. * Stop deleting dimensions when rotating archived metrics if the dimension is active in a different database engine. * Fix old bug in the code that confused obsolete hosts with orphan hosts. * Do not delete multi-host DB host files. * Discard dbengine state when a legacy memory mode instantiates to avoid inconsistencies. * Identify metadata that collide with non-dbengine memory mode hosts and ignore them. * Handle non-dbengine localhost with dbengine archived charts in localhost and streaming. * Ignore archived hosts in streaming. * Add documentation before merging to master.

2020-06-03Fix bugs in streaming and enable support for gap filling (#9214)Andrew Moss
This PR adds (inactive) support that we will use to fill the gaps on chart when a receiving agent goes offline and the sender reconnects. The streaming component has been reworked to make the connection bi-directional and fix several outstanding bugs in the area. * Fixed an incorrect case of version negotiation. Removed fatal() on exhaustion of fds. * Fixed cases that fell through to polling the socket after closing. * Fixed locking of data related to sender and receiver in the host structure. * Added fine-grained locks to reduce contention. * Added circular buffer to sender to prevent starvation in high-latency conditions. * Fixed case where agent is a proxy and negotiated different streaming versions with sender and receiver. * Changed interface to new parser to put the buffering code in streaming. * Fixed the bug that stopped senders from reconnecting after their socket times out - this was part of the scaling fixes that provide an early shortcut path for rejecting connections without lock contention. * Uses fine-grained locking and a different approach to thread shutdown instead. * Added liveness detection to connections to allow selection of the best connection.
