* Keypair: implement clone()
This was not implemented upstream in ed25519-dalek to force everyone to
think twice before creating another copy of a potentially sensitive
private key in memory.
See https://github.com/dalek-cryptography/ed25519-dalek/issues/76
However, there are now 9 instances of
Keypair::from_bytes(&keypair.to_bytes())
in the solana codebase and it would be preferable to have a function.
In particular since this also comes up when writing programs and can
cause users to either start messing with lifetimes or discover the
from_bytes() workaround themselves.
This patch opts to not implement the Clone trait. This avoids automatic
use in order to preserve some of the original "let developers think
twice about this" intention.
* Use Keypair::clone
The commit makes values in stake_delegations map in Stakes struct
generic. Stakes<Delegation> is equivalent to the old code and is used
for backward compatibility in BankFieldsTo{Serialize,Deserialize}.
But banks cache Stakes<StakeAccount> which includes the entire stake
account and StakeState deserialized from account. Doing so, will remove
the need to load stake account from accounts-db when working with
stake-delegations.
* Fix fragile tests in prep of stake rewrite pr
* Restore BOOTSTRAP_VALIDATOR_LAMPORTS where appropriate
* Further clean up
* Further clean up
* Aligh with other call site change
* Remove false warn!
* fix ci!
* SDK: Split new `FeeRateGovernor` out of `FeeCalculator`
Leaving `FeeCalculator` to *only* calculate transaction fees
* Replace `FeeCalculator` with `FeeRateGovernor` as appropriate
* Expose recent `FeeRateGovernor` to clients
* Move `burn()` back into `FeeCalculator`
Appease BPF tests
* Revert "Move `burn()` back into `FeeCalculator`"
This reverts commit f3035624307196722b62ff8b74c12cfcc13b1941.
* Adjust BPF `Fee` sysvar test to reflect removal of `burn()` from `FeeCalculator`
* Make `FeeRateGovernor`'s `lamports_per_signature` private
* rebase artifacts
* fmt
* Drop 'Recent'
* Drop _with_commitment variant
* Use a more portable integer for `target_signatures_per_slot`
* Add docs for `getReeRateCalculator` JSON RPC method
* Don't return `lamports_per_signature` in `getFeeRateGovernor` JSONRPC reply
* Rename bootstrap leader to bootstrap validator
It's a normal validator as soon as other validators enter the
leader schedule.
* cargo fmt
* Fix build
