* Initialize fork graph in program cache during bank_forks creation
* rename BankForks::new to BankForks::new_rw_arc
* fix compilation
* no need to set fork_graph on insert()
* fix partition tests
Duplicate-shreds handler is using a nested hash-map for the incomplete
chunks buffered. This is resulting in a convoluted logic to limit the
number of entries:
https://github.com/solana-labs/solana/blob/427bd6264/gossip/src/duplicate_shred_handler.rs#L62
This commit instead uses a flat buffer mapping (Slot, Pubkey) pairs to
the respective duplicate shreds chunks. The buffer is allowed to grow to
twice the intended capacity, at which point the extraneous entries are
removed in linear time, resulting an amortized O(1) performance.
* 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.
