tracks number of shreds sent and received at different distances from the root (#25989) 2022-06-17 21:33:23 +00:00

enforces that LAST_SHRED_IN_SLOT is also DATA_COMPLETE_SHRED (#24892)
A data shred cannot be LAST_SHRED_IN_SLOT if not also DATA_COMPLETE_SHRED.
So LAST_SHRED_IN_SLOT should also imply DATA_COMPLETE_SHRED:
https://github.com/solana-labs/solana/blob/74b586ae7/ledger/src/shredder.rs#L116-L117
https://github.com/solana-labs/solana/blob/74b586ae7/core/src/broadcast_stage/standard_broadcast_run.rs#L80-L81

However current shred constructs allow specifying a shred which is
LAST_SHRED_IN_SLOT but not DATA_COMPLETE_SHRED:
https://github.com/solana-labs/solana/blob/74b586ae7/ledger/src/shred.rs#L117-L118
https://github.com/solana-labs/solana/blob/74b586ae7/ledger/src/shred.rs#L272-L273

The commit updates ShredFlags so that if a shred is not
DATA_COMPLETE_SHRED it cannot be LAST_SHRED_IN_SLOT either.

replaces Shred::new_empty_coding with Shred::new_from_parity_shard (#24749)
Removing implementation details of shreds and payload offsets from
shredder, so that shredder does not need to mutate payload:
https://github.com/solana-labs/solana/blob/71ad12128/ledger/src/shred.rs#L968-L977

Also, Shred::new_from_data can simply obtain a slice as opposed to
Option<&[u8]>:

removes Shred::new_empty_data_shred (#24714)
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.

hides implementation details of shred from its public interface (#24563)
Working towards embedding versioning into shreds binary, so that a new
variant of shred struct can include merkle tree hashes of the erasure
set.
