* budget and system contracts and verification
* contract check_id methods
* system call contract
* verify contract execution rules
* move system into its own file
* allocate before transfer for budget
* store error in budget context
* budget contract and tests without bank
* moved budget of of bank
* Use multiple sockets for receiving blobs on validators
- The blobs that are broadcasted by leader or retransmitted by peer
validators are received on replicate_port
- Using reuse_addr/reuse_port, multiple sockets can be opened for
the same port
- This allows the kernel to queue data to user space app on multiple
socket queues, preventing over-running one queue
- This helps with reducing packets dropped due to queue over-runs
Fixes#1224
* Fixed failing tests
* Implemented recvmmsg() for UDP packets
- This change implements binding between libc API for recvmmsg()
- The function can receive multiple packets using one system call
Fixes#1141
* Added unit tests for recvmmsg()
* Added recv_mmsg() wrapper for non Linux OS
* Address review comments for recvmmsg()
* Remove unnecessary imports
* Moved target specific dependencies to the function
In the error case that i>0 (we have blobs to send)
we break out of the loop and do not push the allocated r
to the v array. We should recycle this blob, otherwise it
will be dropped.
* fix poll_gossip_for_leader() loop to actually wait
for 30 seconds
* reduce reuseaddr use to only when necessary,
try to avoid already bound sockets
* move nat.rs to netutil.rs
* add gossip tracing to thin_client and bench-tps
* Migrate Budget DSL to use the Account state instead of global bank data structures.
* Serialize Instruction into Transaction::userdata.
* Store the pending set in the Account::userdata
* Enforce the token balance rules on contract execution. This becomes the entry point for generic contracts.
* This pr will have a performance impact on the bank. The next set of changes will fix this by locking each account during multi threaded execution of all the contracts.
* With this change a contract transaction needs to store its state under an address. That address could be the destination of the tokens, or any random address. For the latter, an extra step would be needed to claim the tokens which isn't implemented by budget_dsl at the moment.
* test tracking issue 1157
