* Use local erasure session to create/broadcast coding blobs
* Individual session for each recovery (as the config might be different)
* address review comments
* new constructors for session and coding generator
* unit test for dynamic erasure config
* Implement new Index Column
* Correct slicing of blobs
* Mark coding blobs as coding when they're recovered
* Prevent broadcast stages from mixing coding and data blobs in blocktree
* Mark recovered blobs as present in the index
* Fix indexing error in recovery
* Fix broken tests, and some bug fixes
* increase min stack size for coverage runs
* Ensure signable data is not out of range
* Add a broadcast stage that puts bad sizes in blobs
* Resign blob after modifyign size
* Remove assertions that fail when size != meta.size
* Return result from deserializing blobs in blocktree instead of assuming deserialization will succeed
* Mark bad deserialization as dead fork
* Add test for corrupted blobs in blocktree and replay_stage
* Add DeadSlots column family
* Filter dead forks from get_slots_since
* Mark erroring slots as dead in replay stage, add test
* Mark dead forks in progress instead of removing them
* Fix logging process_entries failures in replay_stage
* Unignore test_fail_entry_verification_leader
* Be able to create bank snapshots
* fix clippy
* load snapshot on start
* regenerate account index from the storage
* Remove rc feature dependency
* cleanup
* save snapshot for slot 0
* Fix inserting bogus is_last blobs into blocktree
* Check for pre-existing blob before insert
* Ignore test that performs concurrent writes on blocktree as that is not supported
* Fix erasure metadata race condition
* make erasure return the underlying error without wrapping it in the `solana::Error` type
* Add metric for erasure failures
* add tests to `ErasureMeta` indexing logic
* Add test to ensure erasure recovery failures don't cause panics
* fix erasure, more tests for full blobs, more metrics
* Revert "Revert "Use Rust erasure library and turn on erasure (#3768)" (#3827)"
This reverts commit 4b8cb72977.
* split out erasure into new crate; add implementation using rust reed-solomon-library
* Track erasures with a &[bool] instead of indexes
* fix bug that reported the number of erasures incorrectly
* Introduce erasure `Session` for consistent config
* Increase test coverage; fix bugs
* Add ability to remove blobs from erasure meta tracking. test added
* Track deletion of coding blobs in blocktree via ErasureMeta. Added to
test
* Remove unused functions in blocktree
* add randomness to recovery thread to exercise recovery due to either new
data or coding blobs
* Add unit test for ErasureMeta index handling
* Re-enable test in broadcast stage
* Add contains_all_parents flag to SlotMeta to prep for tracking detached heads
* Add new DetachedHeads column family
* Remove has_complete_parents
* Fix test
is_rooted is now is_connected and (still) indicates the set of connected
completed slots. 'rooted' slot terminology is used for a different
meaning in bank_forks and replay_stage.
