Convert to use type alias for the callback and cascade the changes to callers. Thanks @jeffwashington for the help making it possible.
Changed the closure for the progress update in the validator main to FnMut and modify the abort count in the closure which is more reliable.
* Move gossip modules to solana-gossip
* Update Protocol abi digest due to move
* Move gossip benches and hook up CI
* Remove unneeded Result entries
* Single use statements
1. Allow the validator bootstrap code to specify the minimal snapshot download speed. If the snapshot download speed is detected below that, a different RPC can be retried. The default is 10MB/sec.
2. To prevent spinning on a number of sub-optimal choices and not making progress, the abort/retry logic is implemented with the following safe guards:
2.1 at maximum we do this retry for 5 times -- this number is configurable with default 5.
2.2 if the download in one notification round (5 second) is more than 2%, do not do retry -- it is not as bad anyway.
2.3 if the remaining estimate time is less than 1 minutes, do not abort retry as it will be done quickly anyway.
2.4 We do this abort/retry logic only at the first notification to avoid wasting download efforts -- the reasoning is being opportunistic and too greedy may not achieve overall shorter download time.
3. The download_snapshot and download_file is modified with the option allowing caller to notified of download progress via a callback. This allows the business logic of retrying to the place it belongs.
* Upgrade Rust to 1.52.0
update nightly_version to newly pushed docker image
fix clippy lint errors
1.52 comes with grcov 0.8.0, include this version to script
* upgrade to Rust 1.52.1
* disabling Serum from downstream projects until it is upgraded to Rust 1.52.1
* purge_old_snapshot_archives is changed to take an extra argument 'maximum_snapshots_to_retain' to control the max number of latest snapshot archives to retain. Note the oldest snapshot is always retained as before and is not subjected to this new options.
* The validator and ledger-tool executables are modified with a CLI argument --maximum-snapshots-to-retain. And the options are propagated down the call chains. Their corresponding shell scripts were changed accordingly.
* SnapshotConfig is modified to have an extra field for the maximum_snapshots_to_retain
* Unit tests are developed to cover purge_old_snapshot_archives
* Deprecate commitment variants
* Add new CommitmentConfig builders
* Add helpers to avoid allowing deprecated variants
* Remove deprecated transaction-status code
* Include new commitment variants in runtime commitment; allow deprecated as long as old variants persist
* Remove deprecated banks code
* Remove deprecated variants in core; allow deprecated in rpc/rpc-subscriptions for now
* Heavier hand with rpc/rpc-subscription commitment
* Remove deprecated variants from local-cluster
* Remove deprecated variants from various tools
* Remove deprecated variants from validator
* Update docs
* Remove deprecated client code
* Add new variants to cli; remove deprecated variants as possible
* Don't send new commitment variants to old clusters
* Retain deprecated method in test_validator_saves_tower
* Fix clippy matches! suggestion for BPF solana-sdk legacy compile test
* Refactor node version check to handle commitment variants and transaction encoding
* Hide deprecated variants from cli help
* Add cli App comments
* Discard pre hard fork persisted tower if hard-forking
* Relax config.require_tower
* Add cluster test
* nits
* Remove unnecessary check
