* Add snapshot_storage_lengths_from_fields
* Add SnapshotUnpacker
* Add SnapshotStorageRebuilder
* Rebuild snapshot storage during unpack
* move snapshot unpacker back into snapshot_utils
* use SerializedAppendVecId in storage rebuilder
* create AccountStorageMap type alias
* Wrap storage and next_append_vec_id in a type
* fixed typo
* move use StorageAndNextAppendVecId
* calculate num_rebuilder_threads more concisely
For backward compatibility, we can only serialize and deserialize
Stakes<Delegation>. However Bank caches Stakes<StakeAccount>. This type
mismatch incurs a conversion cost at epoch boundary when updating
EpochStakes.
This commit adds StakesEnum which allows EpochStakes to include either a
Stakes<StakeAccount> or Stakes<Delegation> and so bypass the conversion
cost between the two at the epoch boundary.
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.
* Moves create_message(), native_invoke() and process_cross_program_instruction()
from the InstructionProcessor to the InvokeContext so that they can have a useful "self" parameter.
* Moves InstructionProcessor into InvokeContext and Bank.
* Moves ExecuteDetailsTimings into its own file.
* Moves Executor into invoke_context.rs
* Moves PreAccount into its own file.
* impl AbiExample for BuiltinPrograms
* add filler accounts to bloat validator and predict failure
* assert no accounts match filler
* cleanup magic numbers
* panic if can't load from snapshot with filler accounts specified
* some renames
* renames
* into_par_iter
* clean filler accts, too
Summary of Changes
Create a plugin mechanism in the accounts update path so that accounts data can be streamed out to external data stores (be it Kafka or Postgres). The plugin mechanism allows
Data stores of connection strings/credentials to be configured,
Accounts with patterns to be streamed
PostgreSQL implementation of the streaming for different destination stores to be plugged in.
The code comprises 4 major parts:
accountsdb-plugin-intf: defines the plugin interface which concrete plugin should implement.
accountsdb-plugin-manager: manages the load/unload of plugins and provide interfaces which the validator can notify of accounts update to plugins.
accountsdb-plugin-postgres: the concrete plugin implementation for PostgreSQL
The validator integrations: updated streamed right after snapshot restore and after account update from transaction processing or other real updates.
The plugin is optionally loaded on demand by new validator CLI argument -- there is no impact if the plugin is not loaded.
This commit adds high-level functions for creating and loading-from
incremental snapshots, plus all low-level functions required to perform
those tasks. This commit **does not** add taking incremental snapshots
as part of a running validator, nor starting up a node with an
incremental snapshot; just laying ground work.
Additionally, `snapshot_utils` and `serde_snapshot` have been
refactored to use a common code paths for the different snapshots.
Also of note, some renaming has happened:
1. Snapshots are now either `full_` or `incremental_` throughout the
codebase. If not specified, the code applies to both.
2. Bank snapshots now are called "bank snapshots"
(before they were called "slot snapshots", "bank snapshots", or
just "snapshots"). The one exception is within `Bank`, where they
are still just "snapshots", because they are already "bank
snapshots".
3. Snapshot archives now have `_archive` in the code. This
should clear up an ambiguity between bank snapshots and snapshot
archives.
