* Add PoH height to process_ledger()
* Moved broadcast_stage Leader Scheduling logic to use Poh height instead of entry_height
* Moved LeaderScheduler logic to PoH in ReplicateStage
* Fix Leader scheduling tests to use PoH instead of entry height
* Change is_leader detection in repair() to use PoH instead of entry height
* Add tests to LeaderScheduler for new functionality
* fix Entry::new and genesis block PoH counts
* Moved LeaderScheduler to PoH ticks
* Cleanup to resolve PR comments
* Added LeaderScheduler module and tests
* plumbing for LeaderScheduler in Fullnode + tests. Add vote processing for active set to ReplicateStage and WriteStage
* Add LeaderScheduler plumbing for Tvu, window, and tests
* Fix bank and switch tests to use new LeaderScheduler
* move leader rotation check from window service to replicate stage
* Add replicate_stage leader rotation exit test
* removed leader scheduler from the window service and associated modules/tests
* Corrected is_leader calculation in repair() function in window.rs
* Integrate LeaderScheduler with write_stage for leader to validator transitions
* Integrated LeaderScheduler with BroadcastStage
* Removed gossip leader rotation from crdt
* Add multi validator, leader test
* Comments and cleanup
* Remove unneeded checks from broadcast stage
* Fix case where a validator/leader need to immediately transition on startup after reading ledger and seeing they are not in the correct role
* Set new leader in validator -> validator transitions
* Clean up for PR comments, refactor LeaderScheduler from process_entry/process_ledger_tail
* Cleaned out LeaderScheduler options, implemented LeaderScheduler strategy that only picks the bootstrap leader to support existing tests, drone/airdrops
* Ignore test_full_leader_validator_network test due to bug where the next leader in line fails to get the last entry before rotation (b/c it hasn't started up yet). Added a test test_dropped_handoff_recovery go track this bug
* Add check in window_service to exit in checks for leader rotation, and propagate that service exit up to fullnode
* Added logic to shutdown Tvu once ReplicateStage finishes
* Added test for successfully shutting down validator and starting up leader
* Add test for leader validator interaction
* fix streamer to check for exit signal before checking socket again to prevent busy leaders from never returning
* PR comments - Rewrite make_consecutive_blobs() function, revert genesis function change
* Move recycler instances to the point of allocation
* sinks no longer need to call `recycle`
* Remove the recycler arguments from all the apis that no longer need them
- The write stage will output vector of entries
- Broadcast stage will create blobs out of the entries
- Helps reduce MIPS requirements for write stage
* rename NodeInfo field of Node from "data" to "info"
(touches a lot of files)
* update client to use gossip to find leader, a la drone
* rework multinode scripts
* move more stuff into rust
* added usage to all
* no more rsync unless you're a validator (TODO: whack that, too)
* fullnode doesn't bail if drone isn't up yet, just keeps trying
* drone doesn't bail if network isn't up yet, just keeps trying
* move gossip/NCP off assuming anything about its address
* use a single socket to send and receive gossip
* remove --addr/-a from CLIs
* rearrange networking utility code
* use Arc<UdpSocket> to share the Sync-safe UdpSocket among threads
* rename TestNode to Node
TODO:
* re-enable 127.0.0.1 as a valid address in crdt
* change repair request/response to a similar, single socket
* pick cloned sockets or Arc<UdpSocket> for all these (rpu uses tryclone())
* update contact_info with network truthiness instead of what the node
says?
