* Moves TransactionContext::get_program_key() to InstructionContext::get_program_key().
* Removes TransactionContext::get_loader_key().
* Test full program and loader executable account chain in BPF loader.
warp_to_slot() first warps to one slot before desired slot in order to
freeze the bank at warp slot. This would cause issues when warping by
one slot as that would attempt to warp to the same slot and hit a sanity
check assertion.
* Adds BorrowedAccount::check_sysvar().
* Adds BorrowedAccount::get_data_mut().
* Implements account resizing in BorrowedAccount.
* Exposes is_signer() and is_writable() in InstructionContext.
* Removes AccountMeta and get_instruction_accounts_metas().
* Makes throwing errors in BorrowedAccount optional.
* Removes result return values from BorrowedAccount.
* Fixup typo
* Add new feature
* Add new TransactionError
* Add framework for checking account state before and after transaction processing
* Fail transactions that leave new rent-paying accounts
* Only check rent-state of writable tx accounts
* Review comments: combine process_result success behavior; log and metrics before feature activation
* Fix tests that assume rent-exempt accounts are okay
* Remove test no longer relevant
* Remove native/sysvar special case
* Move metrics submission to report legacy->legacy rent paying transitions as well
* Refactor Bank::load_and_execute_transactions
* Refactor: improve type safety of TransactionExecutionResult
* Add enum for extra type safety in execution results
* feedback
* Makes error handling in BorrowedAccount optional.
Adds BorrowedAccount ::get_rent_epoch().
Exposes InstructionContext::get_index_in_transaction().
Turns accounts and account_keys into pinned boxed slices.
* Introduces "unsafe" to InvokeContext::push().
* Turns &TransactionContext into &mut TransactionContext in InvokeContext.
* Push and pop InstructionContext in InvokeContext.
Makes test_process_cross_program and test_native_invoke symmetric.
Removes the borrow check from test_invoke_context_verify.
* Removes keyed_accounts from prepare_instruction()
* Removes usage of invoke_stack.
* Removes keyed_accounts from program-test.
* Removes caller_write_privileges.
* Removes keyed_accounts from BPF parameter (de-)serialization.
* Turns compute_units_consumed of ProcessInstructionResult into a &mut parameter.
* Removes second nesting level from test_process_instruction_compute_budget().
* Makes test_process_cross_program and test_native_invoke symmetric.
* Unifies test_process_cross_program(), test_native_invoke() and test_process_instruction_compute_budget() into test_process_instruction().
* Adds TransactionContext, InstructionContext and BorrowedAccount.
* Redirects the usage of accounts in InvokeContext through TransactionContext.
Also use the types declared in transaction_context.rs everywhere.
* Adjusts all affected tests.
* Unifies all InstructionRecorders of a transaction into one.
* Stops explicitly compiling CPI instructions for recording,
uses the indices gathered from instruction_accounts instead.
* Removes message::Message from invoke_context.rs completely.
* Simplifies sol_invoke_signed() of program-test
* Start search for non program accounts at front (instead of the back).
Program and programdata accounts use rposition(), everything else uses position().
* Introduces InstructionAccount which is like AccountMeta but uses an index instead of a Pubkey
* Renames InvokeContext::create_message() to InvokeContext::prepare_instruction()
* Removes Message and CompiledInstruction from InvokeContext interfaces.
* Resolves TODOs of sol_invoke_signed() in program-test.
* Moves CompiledInstruction::visit_each_account() into invoke_context.rs
* Removes Rc and RefCell from PreAccount
* Splits get_account() into find_index_of_account() and get_account_at_index()
in order to remove Rc from return type.
- Lets InvokeContext::process_cross_program_instruction() handle the first invocation depth too.
- Marks InvokeContext::verify(), InvokeContext::verify_and_update() and InvokeContext::process_executable_chain() private.
- Renames InvokeContext::process_cross_program_instruction() to InvokeContext::process_instruction().
- Removes InvokeContext::new_mock_with_sysvars().
