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.

2020-04-03Fix Coverity Defect CID-349684 (#8586)thiagoftsm
This PR brought a test before to call the function `health_add_params` to avoid memory leak.
2020-04-03Fix Coverity defects (#8579)Andrew Moss
Fix Coverity CID355287 and CID355289: technically it is a false-positive but it is easier to put a pattern in the code that they can recognise as a sanitizer. The compiler will remove it during optimization. Fix CID353973: the security condition is unlikely to occur but we can avoid it completely. Fix resource leak from CID 355286 and CID 355288. Fixing new resource leak introduced by a previous commit (CID355449)

2020-03-31Improve the behavior of claiming (#8516)Andrew Moss
The default cloud url has been updated to app.netdata.cloud ready for the release. The claiming process now checks the current user executing claiming and refuses to perform the claim for the wrong user. If the current UID is 0 then claiming proceeds but the file ownership is adjusted to be the correct netdata user. The default expected user is `netdata` unless the script can identify the user from the current configuration. After the claiming script is executed the CLI is used to reload the claiming state.
