* Remove incorrect check
* Move to closure
* Use match statement instead
* Adjust rent_exempt_reserve by existing balance
* Only transfer lamports if rent_exempt_reserve needs are greater than 0
* Rename variable for clarity
* Add minimum-delegation check
* Bump test split amount to meet arbitrary mock minimum-delegation amount
* Add functions to collect executed transactions fee in details;
* remove unnecessary derive attributes
* change function name from add to accumulate; remove collector_fee_details from PartialEq
* add AbiExample
* add test
* share function to withdraw errored transaction
* more tests
* runtime: do fewer syscalls in remap_append_vec_file
Use renameat2(src, dest, NOREPLACE) as an atomic version of if
statx(dest).is_err() { rename(src, dest) }.
We have high inode contention during storage rebuild and this saves 1
fs syscall for each appendvec.
* Address review feedback
* Pass the final result of LastVotedForkSlots aggregation to next
stage and find the heaviest fork we will Gossip to others.
* Change comments.
* Small fixes to address PR comments.
* Move correctness proof to SIMD.
* Fix a broken merge.
* Use blockstore to check parent slot of any block in FindHeaviestFork
* Change error message.
* Add special message when first slot in the list doesn't link to root.
Bubble up the constants to the CLI that control the sizes of the
following two thread pools:
- The thread pool used to replay multiple forks in parallel
- The thread pool used to execute transactions in parallel
#### Problem
The TieredStorageFooter has the min_account_address and
max_account_address fields to describe the account address
range in its file. But the current implementation hasn't updated
the fields yet.
#### Summary of Changes
This PR enables the TieredStorage to persist address range
information into its footer via min_account_address and
max_account_address.
#### Test Plan
Updated tiered-storage test to verify persisted account address range.
#### Problem
The TieredStorage::new_readonly() function currently has the following
problems:
* It opens the file without checking the magic number before checking and loading the footer.
* It opens the file twice: first to load the footer, then open again by the reader.
#### Summary of Changes
This PR refactors TieredStorage::new_readonly() so that it first performs all
checks inside the constructor of TieredReadableFile. The TieredReadableFile
instance is then passed to the proper reader (currently HotStorageReader)
when all checks are passed.
#### Test Plan
* Added a new test to check MagicNumberMismatch.
* Existing tiered-storage tests
* accounts-db: unpack_archive: avoid extra iteration on each path
We used to do a iterator.clone().any(...) followed by
iterator.collect(). Merge the two and avoid an extra iteration and
re-parsing of the path.
* accounts-db: unpack_archive: unpack accounts straight into their final destination
We used to unpack accounts into account_path/accounts/<account> then
rename to account_path/<account>. We now unpack them into their final
destination directly and avoid the rename syscall.
#### Problem
TieredWritableFile currently uses File instead of BufWriter.
This will introduce more syscall when doing file writes.
#### Summary of Changes
This PR makes TieredWritableFile uses BufWriter to allow the
write-call to be more optimized to reduce the number of syscalls.
#### Test Plan
Existing tiered-storage test.
Will run experiments to verify its performance improvement.
#### Dependency
https://github.com/anza-xyz/agave/pull/260
#### Problem
TieredStorageFile struct currently offers new_readonly() and new_writable()
to allow both read and write work-load to share the same struct. However,
as we need the writer to use BufWriter to improve performance as well as
enable Hasher on writes. There is a need to refactor TieredStorageFile to
split its usage for read-only and writable.
#### Summary of Changes
Refactor TieredStorageFile to TieredReadonlyFIle and TieredWritableFile.
#### Test Plan
Existing tiered-storage tests.
* Switch to blockstore.is_full() check because replay thread isn't active.
* Use make_chaining_slot_entries and add first_parent to the method.
Small style fixes.
* Switch to blockstore.is_full() check because replay thread isn't active.
* add `ParseError` in `zk-token-elgamal`
* implement `FromStr` for `ElGamalPubkey` and `ElGamalCiphertext`
* implement `FromStr` for `AeCiphertext`
* fix target
* cargo fmt
* use constants for byte length check
* make `FromStr` functions available on chain
* use macros for the `FromStr` implementations
* restrict `from_str` macro to `pub(crate)`
* decode directly into array
* cargo fmt
* Apply suggestions from code review
