A VoteAccount may only wrap an account if the account owner is
solana_vote_program:id or equivalently this check returns true:
solana_vote_program::check_id(account.owner())
In addition to thread_local -> lazy_static change, a number of thread-pools are
initialized with get_max_thread_count to achieve parity with the older code in
terms of number of validator threads.
* SigVerify: Add total time metrics for dedup/discard/verify
Previously it was impossible to determine the total time the stage spent
on these activities within a measurement window.
* SigVerify: Add _us postfix to time metrics
Shred::new_empty_data_shred returns an invalid shred (i.e.
shred.sanitize() returns error). The method is only used in tests and
can be easily replaced with Shred::new_from_data. To keep the shred api
surface small, this commit removes this method.
The commit makes values in stake_delegations map in Stakes struct
generic. Stakes<Delegation> is equivalent to the old code and is used
for backward compatibility in BankFieldsTo{Serialize,Deserialize}.
But banks cache Stakes<StakeAccount> which includes the entire stake
account and StakeState deserialized from account. Doing so, will remove
the need to load stake account from accounts-db when working with
stake-delegations.
* Pass the sum of consumed compute units to cost_tracker
* cost model tracks builtins and bpf programs separately, enabling adjust block cost by actual bpf programs execution costs
* Copied nightly-only experimental `checked_add_(un)signed` implementation to sdk
* Add function to update cost tracker with execution cost adjustment
* Review suggestion - using enum instead of struct for CommitTransactionDetails

* review - rename variable to distinguish accumulated_consumed_units from individual compute_units_consumed
* not to use signed integer operations
* Review - using saturating_add_assign!(), and checked_*().unwrap_or()
* Review - using Ordering enum to cmp
* replace checked_ with saturating_
* review - remove unnecessary Option<>
* Review - add function to report number of non-zero units account to metrics
Most nodes in the cluster receive the same shred from two different
nodes: parent, and the first node of their neighborhood:
https://github.com/solana-labs/solana/blob/a8c695ba5/core/src/cluster_nodes.rs#L178-L197
Because of the erasure codings, half of the shreds are already
redundant. So this redundant propagation path will only add extra
overhead.
Additionally the very first node of the broadcast tree has 2x fanout
(i.e. 400 nodes) which adds too much load at one node.
This commit simplifies the broadcast tree by dropping the redundant
propagation path and removing the 2x fanout at root node.
- Add write-lock-contention option, replacing same_payer
- write-lock-contention also has a same-batch-only value, where
contention happens only inside batches, not between them
- Rename num-threads to batches-per-iteration, which is closer to what
it is actually doing.
- Add num-banking-threads as a new option
- Rename packets-per-chunk to packets-per-batch, because this is closer
to what's happening; and it was previously confusing that num-chunks
had little to do with packets-per-chunk.

1. use was_executed to correctly identify transactions requires cost adjustment;
2. add function to specifically handle executino cost adjustment without have to copy accounts

Benchmarks show roughly a 6% improvement. The impact could be more
significant when transactions need to be retried a lot.

- don't store pending tx signatures and costs in CostTracker
- apply tx costs to global state immediately again
- go from commit_or_cancel to update_or_remove, where the cost tracker
is either updated with the true costs for successful tx, or the costs
of a retryable tx is removed
- move the function into qos_service and hold the cost tracker lock for
the whole loop
* panic when test timeout
* nonblocking send when when droping banks
* debug log

test_skip_repair in retransmit-stage is no longer relevant because
following: https://github.com/solana-labs/solana/pull/19233
repair packets are filtered out earlier in window-service and so
retransmit stage does not know if a shred is repaired or not.
Also, following turbine peer shuffle changes:
https://github.com/solana-labs/solana/pull/24080
the test has become flaky since it does not take into account how peers
are shuffled for each shred.
