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.
* Inlines MessageProcessor::execute_instruction() in MessageProcessor::process_message().
* Moves MessageProcessor::create_pre_accounts() into ThisInvokeContext::push().
* Move instruction_recorders slice into InvokeContext.
* Makes account_indices optional in InvokeContext::push().
* Separates initial InvokeContext::push() from ThisInvokeContext::new().
* invoke_context.pop() the base invocation frame.
* Zip message.instructions.iter() and program_indices.iter().
* Moves ThisInvokeContext::new() to the beginning of the loop inside MessageProcessor::process_message().
* Hoists ThisInvokeContext::new() out of loop inside MessageProcessor::process_message().
* Removes unnecessary clone() from ThisInvokeContext::new() in MessageProcessor ::process_message().
* Stop ignoring errors from MessageProcessor::create_pre_accounts().
* Moves MessageProcessor::verify_account_references() and MessageProcessor::verify() into InvokeContext::verify().
* Inlines MessageProcessor::execute_instruction() in MessageProcessor::process_message().
* Moves MessageProcessor::create_pre_accounts() into ThisInvokeContext::push().
* Hoists ThisInvokeContext::new() out of loop inside MessageProcessor::process_message().
* Moves MessageProcessor::verify_account_references() and MessageProcessor::verify() into InvokeContext::verify().
* Appends loaders / executable_accounts to accounts in transaction loading.
* Adds indices to loaders / executable_accounts.
* Moves MessageProcessor::create_keyed_accounts() into InvokeContext::push().
* Removes "executable_accounts",
now referenced by transaction wide index into "accounts".
* Removes create_pre_accounts() from InstructionProcessor,
as it is already in MessageProcessor.
* Collect program account indices directly in load_executable_accounts().
* Return error if Transaction locks an executable as writable
* Return error if a ProgramData account is writable but the upgradable loader isn't present

* Add new TransactionError
* Disallow writes to any upgradeable-loader account when loader not present; remove is_upgradeable_loader_present exception for all other executables
* Handle cleaning zero-lamport accounts
Handle cleaning zero-lamport accounts in slots higher than the last full
snapshot slot. This is part of the Incremental Snapshot work.
Fixes#18825
* added realtime cost checking logic to reject block that would exceed max limit:
- defines max limits at block_cost_limits.rs
- right after each bath's execution, accumulate its cost and check again
limit, return error if limit is exceeded
* update abi that changed due to adding additional TransactionError
* To avoid counting stats mltiple times, only accumulate execute-timing when a bank is completed
* gate it by a feature
* move cost const def into block_cost_limits.rs
* redefine the cost for signature and account access, removed signer part as it is not well defined for now
* check if per_program_timings of execute_timings before sending
* Add deprecated tag to Bank::get_blockhash_last_valid_slot
* Update SendTransactionService to use last_valid_block_height
* Update solana-tokens to use last_valid_block_height
* Remove dangling file
* Update solana program to use last_valid_block_height
* Update Banks crates to use last_valid_block_height
Filtering out storages for incremental snapshots will be needed by the
background services for incremental snapshot support, but there is not a
Bank at that point. Since the filtering doesn't apply only to Bank, and
more to snapshots, move the functionality into snapshot_utils.
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.
* feature: add new token program feature
* Fixup test
* Update to spl-token v3.2.0
* Update Cargo.lock + fmt
* Update token program version in fetch-spl.sh
* Bump associated token program to 1.0.3
* Add aToken so
* Move transaction sanitization earlier in the pipeline
* Renamed HashedTransaction to SanitizedTransaction
* Implement deref for sanitized transaction
* bring back process_transactions test method
* Use sanitized transactions for cost model calculation
* Changes ThisInvokeContext::get_account() to use accounts instead of pre_accounts.
* Adds explicit keys to accounts to make them symmetric to account_deps.
* Appends account_deps to accounts in transaction loading and removes account_deps everywhere else.
