* Hash to signature constraints migration #1 * After rebase from Attachments Classloader commit. * Simplified implementation without CZ whitelisting and relaxing the no-overlap rule slightly. * Further simplification. * Detailed implementation. * Use fully loaded Cash contract jar for hash to signature constraints migration test. Additional debug logging. * Minor cleanup. * Address PR review feedback. * Minor fix. * Fixes following rebase from master. * Implemented `calculateEntriesHashes` to improve classloader validation performance. * Address minor PR review comments. * Added integration tests and some minor fixes. * Minor fixes following rebase from master. * Updates and fixes following integration testing. * Added changelog entry. * Fix broken unit tests. * Fix compilation errors in DriverDSL tests after rebase from master. * Minor fix to test cordapp jar signing using explicit keystore. * Run hash-to-signature constraints integration test out of process using a non-validating notary. * Address PR review feedback: contract version from database + other minor changes. * Address final PR review feedback: remove signed attachment field from attachmentWithContext * Resolve conflicts following rebase from master. * Fix failing junit test. * Fix Kryo serialization error (forgot to write new `version` identifier field) * Removed redundant query carried over from previous commit. * Added documentation. * Fix test case where explicit Hash Constraint input and Signature Constraint output explicitly configured. * Addressing PR review comments from SA. * AttachmentQueryCriteria API: added wither methods and Java Unit tests. * Fixed compilation error caused by Unit tests being in wrong module. * Added @CordaInternal to canBeTransitionedFrom function. * Minimized AttachmentClassloader overlap duplicates checking. * Moved JarSignatureTestUtils and ContractJarTestUtils to internal pending clean-up and documentation before public release. * Minor fix following rebase from master. * Removed redundant checkNotNull(networkParameters) checks now that these are always passed into the main (non-deprecated) constructor. * Remove capitalization. |
