* Move ConnectionCache back to solana-client, and duplicate ThinClient, TpuClient there
* Dedupe thin_client modules
* Dedupe tpu_client modules

* Split out voting and banking threads in banking stage
Additionally this allows us to aggressively prune the buffer for voting threads
as with the new vote state only the latest vote from each validator is
necessary.

- Batch filtering invalid transactions (fail to sanitize, too old or already processed) before forwarding
- Combine packet filtering and forwarding to share sanitized transactions
- `iter_desc` is no longer needed, remove it;
- Add a method to share the logic of removing packets from buffer after they were removed from MinMaxHeap
- Add test coverage for forward_packet_batches_by_accounts
- rebase, resolve conflicts
Given the 32:32 erasure recovery schema, current implementation requires
exactly 32 data shreds to generate coding shreds for the batch (except
for the final erasure batch in each slot).
As a result, when serializing ledger entries to data shreds, if the
number of data shreds is not a multiple of 32, the coding shreds for the
last batch cannot be generated until there are more data shreds to
complete the batch to 32 data shreds. This adds latency in generating
and broadcasting coding shreds.
In addition, with Merkle variants for shreds, data shreds cannot be
signed and broadcasted until coding shreds are also generated. As a
result *both* code and data shreds will be delayed before broadcast if
we still require exactly 32 data shreds for each batch.
This commit instead always generates and broadcast coding shreds as soon
as there any number of data shreds available. When serializing entries
to shreds:
* if the number of resulting data shreds is less than 32, then more
coding shreds will be generated so that the resulting erasure batch
has the same recovery probabilities as a 32:32 batch.
* if the number of data shreds is more than 32, then the data shreds are
split uniformly into erasure batches with _at least_ 32 data shreds in
each batch. Each erasure batch will have the same number of code and
data shreds.
For example:
* If there are 19 data shreds, 27 coding shreds are generated. The
resulting 19(data):27(code) erasure batch has the same recovery
probabilities as a 32:32 batch.
* If there are 107 data shreds, they are split into 3 batches of 36:36,
36:36 and 35:35 data:code shreds each.
A consequence of this change is that code and data shreds indices will
no longer align as there will be more coding shreds than data shreds
(not only in the last batch in each slot but also in the intermediate
ones);
- Forward packets by prioritization in desc order
- Add support of cost-tracking by transaction requested compute units
- Hook up account buckets to forwarder
- Add metrics for forwardable batches count
- Remove redundant invalid packets filtering at end of slot since forwarder will do the same when batch forwardable packets
- Add bench test for forwarding
Fully deserializing shreds in window-service before sending them to
retransmit stage adds latency to shreds propagation.
This commit instead channels through the payload and relies on only
partial deserialization of a few required fields: slot, shred-index,
shred-type.
Following commits will skip shreds deserializaton before retransmit, and
so we will only have a ShredId and not a fully deserialized shred to
obtain the shuffling seed from.
* Define shuffle to prep using same shuffle for multiple slices
* Determine transaction indexes and plumb to execute_batch
* Pair transaction_index with transaction in TransactionStatusService
* Add new ReplicaTransactionInfoVersion
* Plumb transaction_indexes through BankingStage
* Prepare BankingStage to receive transaction indexes from PohRecorder
* Determine transaction indexes in PohRecorder; add field to WorkingBank
* Add PohRecorder::record unit test
* Only pass starting_transaction_index around PohRecorder
* Add helper structs to simplify test DashMap
* Pass entry and starting-index into process_entries_with_callback together
* Add tx-index checks to test_rebatch_transactions
* Revert shuffle definition and use zip/unzip
* Only zip/unzip if randomize
* Add confirm_slot_entries test
* Review nits
* Add type alias to make sender docs more clear
In prepration of
https://github.com/solana-labs/solana/pull/25807
which reworks erasure batch sizes, this commit:
* adds a helper function mapping the number of data shreds to the
erasure batch size.
* adds ProcessShredsStats to Shredder::entries_to_shreds in order to
replace and remove entries_to_data_shreds from the public interface.
* client: Remove static connection cache, plumb it instead
* Add TpuClient::new_with_connection_cache to not break downstream
* Refactor get_connection and RwLock into ConnectionCache
* Fix merge conflicts from new async TpuClient
* Remove `ConnectionCache::set_use_quic`
* Move DEFAULT_TPU_USE_QUIC to client, use ConnectionCache::default()
Upcoming changes to PacketBatch to support variable sized packets will
modify the internals of PacketBatch. So, this change removes usage of
the internal packet struct and instead uses accessors (which are
currently just wrappers of Vector functions but will change down the
road).
* - get prioritization fee from compute_budget instruction;
- update compute_budget::process_instruction function to take instruction iter to support sanitized versioned message;
- updated runtime.md
* update transaction fee calculation for prioritization fee rate as lamports per 10K CUs
* review changes
* fix test
* fix a bpf test
* fix bpf test
* patch feedback
* fix clippy
* fix bpf test
* feedback
* rename prioritization fee rate to compute unit price
* feedback

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.
