The parameter is now a required third argument. This is because authorized
withdrawer should never be the same as vote account keypair or validator
identity keypair for security reasons.
Added a --allow-unsafe-authorized-withdrawer to override this restriction if
necessary.
#### Problem
There's no way to get incremental snapshot information from RPC.
#### Summary of Changes
- Add new RPC method, `getHighestSnapshotSlot` that returns a `SnapshotSlotInfo`, which contains both the highest full snapshot slot, and the highest incremental snapshot slot _based on_ the full snapshot.
- Deprecate old RPC method, `getSnapshotSlot`
- Update API docs
Fixes#19579
This is the 2nd installment for the AccountsDb replication.
Summary of Changes
The basic google protocol buffer protocol for replicating updated slots and accounts. tonic/tokio is used for transporting the messages.
The basic framework of the client and server for replicating slots and accounts -- the persisting of accounts in the replica-side will be done at the next PR -- right now -- the accounts are streamed to the replica-node and dumped. Replication for information about Bank is also not done in this PR -- to be addressed in the next PR to limit the change size.
Functionality used by both the client and server side are encapsulated in the replica-lib crate.
There is no impact to the existing validator by default.
Tests:
Observe the confirmed slots replicated to the replica-node.
Observe the accounts for the confirmed slot are received at the replica-node side.
* Add note about ASK keyword to paper wallet doc
Per https://github.com/solana-labs/solana/issues/17325#issuecomment-844434585, this change adds a note to the paper wallet docs mentioning the use of the `ASK` keyword.
Also specifes that the `solana-keygen pubkey prompt://` command returns a derived bip44 base address.
(I'm new to Solana development and this was a point of confusion for me, only resolved by finding this issue)
* Update docs/src/wallet-guide/paper-wallet.md

Problem
Validators fall behind the network when bogged down by heavy RPC load. This
seems to be due to a combination of CPU load and lock contention caused by
serving RPC requests. The most expensive RPC requests involve account scans.
Summary of Changes
The AccountsDb replication design proposal is described.
I wanted to use this sysvar to get a recent block hash, but I didn't
know whether the first or the last entry contains the most recent block
hash.
By calling it for mainnet, printing the results, and comparing that to
the recent blocks on solanabeach.io/blocks, I discovered that the
entries are ordered from most recent to least recent. Document this to
save future readers the trouble.
* Zelcore wallet support for SOL/SPLs info added
I have added a quick infodump about Zelcore wallet supporting various features of the Solana ecosystem. I looked at previous commits and it seemed adding to the top of the file was the norm, but please feel free to move around if needed.
* Zelcore wallet info moved to bottom of file.
