* ENT-11728: Switched to LTS version of BC. Also removed PQC algos as not supported in LTS.
* ENT-11728: Removed the SPHINCS PQC algorithm.
* ENT-11728: Added dependency on bcutil to fix missing class error.
The `TransactionBuilder` has been updated to look for any missing dependencies to legacy contract attachments, in the same way it does for missing dependencies for CorDapps in the "cordapps" directory,
Since `TransactionBuilder` does verification on the `WireTransaction` and not a `SignedTransaction`, much of the verification logic in `SignedTransaction` had to moved to `WireTransaction` to allow the external verifier to be involved. The external verifier receives a `CoreTransaction` to verify instead of a `SignedTransaction`. `SignedTransaction.verify` does the signature checks first in-process, before then delegating the reset of the verification to the `CoreTransaction`.
A legacy contract dependency is defined as an attachment containing the missing class which isn't also a non-legacy Cordapp (i.e. a CorDapp which isn't in the "cordapp" directory).
The various crypto tests that were previously ignored have been re-enabled.
The abandoned i2p EdDSA library has been replaced with native support that was added in Java 15.
Java 17 (via the `SunEC` provider) does not support the secp256k1 curve (one of the two ECDSA curves supported in Corda). This would not normally have been an issue as secp256k1 is already taken care of by Bouncy Castle. However, this only works if the `Crypto` API is used or if `”BC”` is explicitly specified as the provider (e.g. `Signature.getInstance(“SHA256withECDSA”, “BC”)`). If no provider is specified, which is what is more common, and actually what the Java docs recommend, then this doesn’t work as the `SunEC` provider is selected. To resolve this, a custom provider was created, installed just in front of `SunEC`, which “augments” `SunEC` by delegating to Bouncy Castle if keys or parameters for secp256k1 are encountered.
`X509Utilities.createCertificate` now calls `X509Certificate.verify()` to verify the created certificate, rather than using the Bouncy Castle API. This is more representative of how certificates will be verified (e.g. during SSL handshake) and weeds out other issues (such as unsupported curve error for secp256k1).
`BCCryptoService` has been renamed to `DefaultCryptoService` as it no longer explicitly uses Bouncy Castle but rather uses the installed security providers. This was done to fix a failing test. Further, `BCCryptoService` was already relying on the installed providers in some places.
The hack to get Corda `SecureRandom` working was also resolved. Also, as an added bonus, tests which ignored `SPHINCS256_SHA256` have been reinstated.
Note, there is a slightly inconsistency between how EdDSA and ECDSA keys are handled (and also RSA). For the later, Bouncy Castle is preferred, and methods such as `toSupportedKey*` will convert any JDK class to Bouncy Castle. For EdDSA the preference is the JDK (`SunEC`). However, this is simply a continuation of the previous preference of the i2p library over Bouncy Castle.
* It uses URLs when in fact CorDapps are jar files, and so should being Path. It also does URL equality, which is not recommended
* Address (very old) TODO of removing RestrictedURL, which is not needed
Also, back-ported some minor changes from https://github.com/corda/enterprise/pull/5057.
The node now sends a transaction to the verifier if any of its attachments were compiled with Kotlin 1.2 (the net.corda.node.verification.external system property has been removed). It uses kotlinx-metadata to read the Kotlin metadata in the attachment to determine this. For now this scanning is done each time the attachment is loaded from the database.
The existing external verification integration tests were converted into smoke tests so that 4.11 nodes could be involved. This required various improvements to NodeProcess.Factory. A new JAVA_8_HOME environment variable, pointing to JDK 8, is required to run these tests.
There is still some follow-up work that needs to be done:
Sending transactions from a 4.11 node to a 4.12 node works, but not the other way round. A new WireTransaction component group needs to be introduced for storing 4.12 attachments so that they can be safely ignored by 4.11 nodes, and the 4.12 node needs to be able to load both 4.11 and 4.12 versions of the same contracts CorDapp so that they can be both attached to the transaction.
Even though attachments are cached when retrieved from the database, the Kotlin metadata version should be stored in the attachments db table, rather than being scanned each time.
Finally, VerificationService was refactored into NodeVerificationSupport and can be passed into SignedTransaction.verifyInternal, instead of needing the much heavier VerifyingServiceHub. This makes it easier for internal tools to verify transactions and spawn the verifier if necessary.
Major changes due to JDK 17:
1. JDK17 JCE Provider now has built-in support for eddsas, corda uses
the bouncycastle (i2p) implementation. This PR removes the conflicting
algorithms from the built-in JCE provider.
2. JavaScript scripting has been removed from the JDK, the corda log4j config was using
scripting to conditionally output additional diagnostic info if the MDC
was populated. This PR has removed the scripting.
3. The artifactory plug-ins used are now deprecated, this PR has removed them
and uses the same code as Corda 5 for publishing to artifactory.
4. Javadoc generation has been modified to use the latest dokka plug-ins.
5. Gradle 7.6 has implemented an incredibly annoying change where transitive
dependencies are not put on the compile classpath, so that they have to be
explicitly added as dependencies to projects.
6. Mockito has been updated, which sadly meant that quite a few source files
have to changes to use the new (org.mockito.kotlin) package name. This makes
this PR appear much larger than it is.
7. A number of tests have been marked as ignored to get a green, broadly they fall
into 3 classes.
The first is related to crypto keypair tests, it appears some logic
in the JDK prefers to use the SunJCE implementation and we prefer to use
bouncycastle. I believe this issue can be fixed with better test setup.
The second group is related to our use of a method called "uncheckedCast(..)",
the purpose of this method was to get rid of the annoying unchecked cast compiler
warning that would otherwise exist. It looks like the Kotlin 1.9 compiler type
inference differs and at runtime sometimes the type it infers is "Void" which causes
an exception at runtime. The simplest solution is to use an explicit cast instead of
unchecked cast, Corda 5 have removed unchecked cast from their codebase.
The third class are a number of ActiveMQ tests which appear to have a memory leak somewhere.
* Moved core.flows and core.contract tests
* move internal tests
* move node, schemas and serialization tests
* Move transactions tests
* Move test access helper into test package
* Move remaining tests, and create access helpers to test internals.
* Fix test dependencies.
* Delete some cruft that flagged up on the API checker
* Add readme explaing where tests need to go.
* fix typo
