When broadcasting shreds, turbine excludes the slot leader from the
random shuffle. Doing so, shreds should never loopback to the leader.
If shreds reaching retransmit stage are from the node's own leader slots
they should not be retransmited to any nodes.
* First draft of ingesting duplicate proofs in Gossip into blockstore.
* Add more unittests.
* Add more unittests for bad cases.
* Fix lint errors for tests.
* More linter fixes for tests.
* Lint fixes
* Rename get_entries, move location of comment.
* Some renaming changes and comment fixes.
* Fix compile warning, this enum is not used.
* Fix lint errors.
* Slow down cleanup because this could potentially be expensive.
* Forgot to reset cleanup count.
* Add protection against attackers when constructing chunk map when
we ingest Gossip proofs.
* Use duplicate shred index instead of get_entries.
* Rename ClusterInfoDuplicateShredListener and fix a few small problems.
* Use into_shreds to piece together the proof.
* Remove redundant code.
* Address a few small errors.
* Discard slots too advanced in the future.
* - Use oldest proof for each pubkey
- Limit number of pubkeys in each slot to 100
* Disable duplicate shred handling for now.
* Revert "Disable duplicate shred handling for now."
This reverts commit c3fcf403876cfbf90afe4d2265a826f21a5e24ab.
* Increase turbine propagation const
Value is used as a delay threshold for issuing shred repairs and analysis is showing we are overly aggressive in requesting repairs. Shreds show up via turbine before the repair completes the vast majority of the time
* Use Duration type for MAX_TURBINE_PROPAGATION
Store non-vote transaction counts that are now recorded by the banks
into the `blockstore`.
`SamplePerformanceService` now populates `PerfSampleV2` with counts from
the banks.
Problem
The plugins need to know when all transactions for a block have been all notified to serve getBlock request correctly. As block and transaction notifications are sent asynchronously to each other it will be difficult.
Summary of Changes
Include the executed transaction count in block notification which can be used to check if all transactions have been notified.
The commit adds an associated SignedData type to Shred trait so that
merkle and legacy shreds can return different types for signed_data
method.
This would allow legacy shreds to point to a section of the shred
payload, whereas merkle shreds would compute and return the merkle root.
Ultimately this would allow to remove the merkle root from the shreds
binary.
The commit allocates 2% of slots to running experiments with different
turbine fanouts based on the slot number.
The experiment is feature gated with an additional feature to disable
the experiment.
* Plumb dumps from replay_stage to repair
When dumping a slot from replay_stage as a result of duplicate or
ancestor hashes, properly update repair subtrees to keep weighting and
forks view accurate.
* add test
* pr comments
* Support bi-directional quic communication, use the same endpoint for the quic server and client
This is needed for supporting using quic for repair
* Added comments on the bi-directional communication tests
* Removed some debug logs
* clippy issue
