* pg: distributed named process groupsMaxim Fedorov2020-02-051-1/+2
| | | | | | | | | | | | | | | | | | | | | | | Replacement for pg2 module. Differences (compared to pg2): * non-existent and empty group treated the same (empty list of pids), thus create/1 and delete/1 have no effect (and not implemented). which_groups() return only non-empty groups * no cluster lock required, and no dependency on global * all join/leave operations require local process (it's not possible to join a process from a different node) * multi-join: join/leave several processes with a single call Empty groups are not supported: unlike a process, group does not have originating node. So it's possible that during net split one node deletes the group, that still exists for another partition. pg2 will re-create deleted group as soon as net split converges, which is quite unexpected. Process groups can be organised into multiple scopes. Scopes are completely independent of each other. A process may join any number of groups in any number of scopes. Scopes are designed to decouple single mesh into a set of overlay networks, reducing amount of traffic required to propagate group membership information.

|\ | | | | | | | | | | * john/erts/cleanup-allocator-statistics/OTP-16327: erts: Include block types in allocation statistics instrument: Include allocation types in carrier statistics
| * erts: Include block types in allocation statisticsJohn Högberg2020-01-072-9/+18
| | | | | | | | | | | | | | | | | | | | Now that carriers can migrate freely, a binary allocator may find itself responsible for a bunch of heap fragments. We used to present such blocks as if they were still in the pool ("foreign blocks") but it was a bit too counter-intuitive. This commit presents all blocks on the allocator that employs their carrier, regardless of their type.

| * erts: Remove scheduler_poll lttng eventLukas Larsson2019-09-111-8/+0
| | | | | | | | | | This event is not really useful for anything since the poll events moved to a seperate thread so remove it.
| * erts: Remove the aio dtrace and lttng probesLukas Larsson2019-09-111-17/+0
| | | | | | | | | | | | Since file IO does not go via the async threads any more these probes are not really usefull so we remove them rather than have to maintain them.
