James Higgs 44428b6048 ENT-3801 Backport to OS (#5355) ... * [ENT-3801] Store transactions in the database during transaction resolution (#2305) * ENT-3801: Store downloaded txns as part of the backchain resolution into the db rather than the checkpoint It's very inefficient to store the downloaded backchain in the checkpoint as more of it downloaded. Instead, if a threshold is reached (which currently defaults at 0) then the backchain is stored in the transactions table as unverified. A new is_verified column has been added to track this. Initially testing on the OS codebase has been very promising but unfortunately this current code is not quite ready. I had to quickly port it to ENT as this is meant to be an ENT-only optimisation. To that effect, there is a TransactionResolver abstraction with two implementations: an in-memory one which has the old behaviour, and which will be the behaviour for OS, and a db one. DBTransactionStorage hasn't been fully updated and I had to comment out the optimistic path for now. Most of these changes will need to be ported to OS to keep the merge conflicts in check, but obviously not DbTransactionsResolver and the "is_verified" changes in DBTransactionStorage. DBTransactionStorage does have other refactoring which will make sense to port though. * [ENT-3801] Start work on allowing modifications in AppendOnlyPersistentMap * [ENT-3801] Add transaction resolver tests * [ENT-3801] Adjust suspendable annotations * [ENT-3801] Fix the ResolveTransactionFlow tests * [ENT-3801] Update ResolveTransactionsFlow tests * [ENT-3801] Add a liquibase migration script for isVerified * [ENT-3801] Ensure the migration runs in the correct place * [ENT-3801] Handle resolution of already present transactions * [ENT-3801] Fix compile error in performance test app * [ENT-3801] Logging and comment updates, plus a test case * [ENT-3801] Add a notary change resolution test * [ENT-3801] Add a contract upgrade transaction test * [ENT-3801] Change new column to be a character based status * [ENT-3801] Migration script type change * [ENT-3801] Address first round of review comments * [ENT-3801] Update variable names in AppendOnlyPersistentMap * [ENT-3801] Another variable name clarification * [ENT-3801] Fix missing name changes * [ENT-3801] Make the signature list immutable when constructing cache value * [ENT-3801] Add a locking strategy for unverified transactions * [ENT-3801] Address tidying up review comments * [ENT-3801] First attempt at ensuring locks are released after commit * [ENT-3801] Remove references to old cache name * [ENT-3801] Update locking logic * [ENT-3801] Fix potential deadlock with read/write transaction locks * [ENT-3801] Remove read locks, and ensure minimal extra suspends * [ENT-3801] Fix build issues in tests * [ENT-3801] Use the correct clock when calculating sleep durations * [ENT-3801] Add a pessimism flag for writing verified transactions * [ENT-3801] Change logging statement to debug (cherry picked from commit 8ab6a55e17) * [NOTICK] Fix up imports for some changed files * [NOTICK] Fix transaction resolution tests * [NOTICK] Reinstate the DBTransactionsResolver * [NOTICK] Add the topological sort back to recordTransactions * [NOTICK] Adjust test case to remove dependency on query ordering * [NOTICK] Make test code match that in ENT		2019-08-07 16:49:49 +01:00
