CORDA-3603 Save completed flow information (#6034)
When a flow is finished do not delete the checkpoint from the DB.

Instead, the FlowStatus is marked as Completed in the DB.

Updated numerous tests which relied on the flow being removed
when finished.

7f62046c2f CORDA-3329 Exceptions thrown in raw vault observers can cause critical issues (#5816)
Observers registered on NodeVaultService#rawUpdates, if they throw an exception when called from serviceHub#recordTransactions and if this exception is not handled by the flow hospital, then this leads to the transaction not being recorded in the local vault. This could get the ledger in an out of sync state.

In the specific case this happens within FinalityFlow#notariseAndRecord this leads to the transaction being notarized but not recorded in the local vault nor broadcasted in any counter party. The -failed to be recorded locally- transaction and its output states are not visible to any vault, and its input states not able to consumed by a new transaction, since they are recorded as consumed within the Notary. In this specific case we need not loose, by any means, the current transaction.

We will handle all cases by catching all exceptions thrown from serviceHub#recordTransactions, wrapping them with a HospitalizeFlowException and throwing it instead. The flow will get to the hospital for observation to be retried from previous checkpoint on next node restart.

4bae045a58 ENT-4601 Public API to run external operations from a flow (#5833)
Deprecate FlowAsyncOperation and reimplement public versions FlowExternalOperation and FlowExternalAsyncOperation.

await added to FlowLogic to allow easy calling from both Java and Kotlin. There are two overrides of await (one for FlowExternalOperation and FlowExternalAsyncOperation).

Implementations of FlowExternalOperation return a result (written as blocking code) from their execute function. This operation will then be executed using a thread provided by the externalOperationExecutor.

Implementations of FlowExternalAsyncOperation return a future from their execute function. This operation must be executed on a newly spawned thread or one provided by a thread pool. It is up to developers to handle threading in this scenario.

The default thread pool (externalOperationExecutor) can be configured through the flowExternalOperationThreadPoolSize node config.

The current implementation leaves FlowAsyncOperation alone, meaning that any developers that have used it (even though it is internal) won't need to change their apps. If this was not concern I would delete it completely and replumb the state machine code. Instead, it has been marked with @DoNotImplement and executeAsync is annotated with @Deprecated

a7147c1ffd ENT-4652: Provide an "attachment fixup" mechanism to repair broken transactions. (#5825)
* Do not register cordapp custom serialisers when using attachment classloader.

* Record the URLs of CorDapp JARs that contain custom serialisers. Include these JARs as extra attachments if we discover that we're missing a custom serialiser during transaction verification.

* Check for disabled serializer when explicitly requesting a custom serializer.
Refactor test case to force use of a custom serializer.

* Tidy up basic custom serializer test.

* Also test that TransactionBuilder rejects missing custom serializers.

* Remove test whitelists, which should not be needed with custom serialisers.

* Add changelog entry. Also align TestCordappImpl.findRoots() with OS backports.

* Second approach based around CorDapps inside AttachmentStorage - report missing type descriptor or any non-composable types.

* Initial implementation of Corda-Fixup rules inside a CorDapp jar.

* Replace original "automatic attachment fixing" mechanism completely.

* First review comments: restore "missing class" logic to TransactionBuilder.

* Restore "missing class" mechanism as fallback for SignedTransaction too.

* Quick and dirty change to stop "Unable to start notaries." error message (#5686)

"Unable to start notaries. A required port might be bound already" is
returned whenever a startup error occurs while starting the notary nodes
in driver tests. This hides the real error.

This change prints the actual error to std_err and read from file
at a later point. This means the real error is not lost and will be
shown in failed builds.

91e6c9783f TM-51 Read and write test results to artifactory. (#5597)
* TM-51  Prep for reading and writing test results to artifactory.

* TM-51  Tests from target branch if no tests for current branch

* TM-51  Placeholder for test averaging over runs.

* TM-51  Replace slashes in branch names used as tags.

* TM-51  More placeholder work for the mean duration work.

* TM-51  Write out average tests results as as csv.

The csv file should grow and be updated on each run.  This includes whether or not we are running unit tests, integration tests and so on.

* TM-51  Comment out old junit test archiving, add more comments.

* TM-51  Zip task needs to depend on a csv creation task.

If there isn't a csv file present, then the zip task doesn't run due to 'NO-SOURCE'

* TM-51  Zip task should ignore empty dirs

* TM-51  Fix up loading of test results.

We were looking for the wrong artifact name.
Add a bit more logging.

* TM-51  Fix up possible problem with allocating by class distribution.

If we encounter a class we haven't seen before, there won't be any tests.
This means we should give it some weight.  '1' is far too small.

* TM-51  Test that we are definitely increment the run count.

Tracking down whether the zipped csv file should have incremented.

* TM-51  Better default value for missing test/class names.

Begin by using mean unit test duration, but we have the option to bump
that to the mean class unit tests duration.

* TM-51  More debug information around csv writing.

We should be incrementing the tests.

* TM-51  Reload the csv before updating it.

* TM-51  Reduce verbosity of logging.

* TM-51  Reinstate unit tests.  Remove logging verbosity.

* TM-51  Load tests from artifactory in memory and avoid interim file.

* TM-51  Better handling of zero duration tests.

Ensure we return zero times from junit artifacts which may either be zero or have no recorded time.  Before writing the tests duration csv file, store those with a known time, and then store those with zero using the average time.

* TM-51  Log whether we have recorded a test.

Tracking down the curious case where we seem to not be rerunning the
same set of tests on the second run.

* TM-51  Capture junit files as well.

Trying to track down whether some tests are intermittently run.

* TM-51  Change task dependencies to ensure ziptask is triggered.

* TM-51  Remove test assertion, and trigger build

* TM-51  Add corda/enterprise to artifactory tag name.

Moved properties to own file.

* TM-51  Remove unnecessary mean class-based duration.

* TM-51  Add more BucketingAllocator tests.

We need these to nail down its behaviour some more.

* TM-51  Further log information.

We don't seem to be finding the tests in the 'production' runs which is odd.

* TM-51  corda type double set?

* TM-51  do not set the project type in the properties.

SRP and all that.

* TM-51  better plan reporting

* TM-51  duration may be zero

Another runtime problem that doesn't show in tests.

* TM-51  better plan reporting

* fix missing space after image id

* fix merge issue in DistributedTesting

* TM-51  remove unused code when GET/PUT-ting to Artifactory.

* TM-51  put tasks in gradle group and tidy up zip task creation

* TM-51 Fix the junit XML path.

* TM-51 Fix the task graph

* TM-51 Less logging

268d129838 CORDA-3194 Replay start flow events when responding flow fails initial checkpoint commit (#2601)
* CORDA-3194 Replay start flow events when responding flow fails initial checkpoint commit

Logic has already been added to recover from initial checkpoint commit
failures on the initiating flow side but this did not suffice for
the same failure occurring on the responding flow's side.

The same idea has been added to resolve the responding flow's issue.

`ExternalMessageEvent` now has a `flowId` that is maintained on the
event. Messages can then be replayed to start/restart the flow, while
the event provides the flow id to each flow start.

Each `ExternalMessageEvent` implementation generates a random `flowId`
when constructed.

Events are stored in Artemis. This allows the solution to recover across
node restarts as the events will be pulled from artemis again when
restarting.

In the future `flowId`s will probably moved off of the events and
generated purely on the responding flow's node.

* CORDA-3194 Add test to verify that errors removing a responding flow are recoverable

4cbe22949d CORDA-3018 Whitelisting attachments by public key - phase two tooling (#5386)
Allow node operators to blacklist signing keys (using blacklistedAttachmentSigningKeys config option). These blacklisted keys prevent attachments that are received over the network from being trusted. The docs have been updated to detail how to generate the key hashes that the config requires.

A new shell command attachments trustRoots has been added to see what attachments exist on the node along with information about their trust and where it comes from.

run dumpCheckpoints has been replaced by checkpoints dump as InternalCordaRPCOps needed to change to prevent a function that is meant to be internal from being visible on the shell.

fc265ee472 CORDA-3018 Whitelisting attachments by public key - relax signer restrictions (#5358)
* CORDA-3018 Allow loading an untrusted contract jar if another attachment exists that was signed with the same keys and uploaded by a trusted uploader

`TransactionUtils.isAttachmentTrusted` requirements have been relaxed
to allow an untrusted attachment to be loaded as long as another
attachment exists that is signed by the same keys and was uploaded
by a trusted uploader.

The requirement of containing the same contract classes has been
removed. Therefore the contents of the existing trusted attachment
no longer matters.

* CORDA-3018 Allow a subset/intersection of signers in `isAttachmentTrusted`

Allow a subset/intersection of signers to satisfy the signer
requirements of `isAttachmentTrusted`. This allows an "untrusted"
attachment that is signed by one or more keys to be "trusted" as long
as another trusted attachment already exists that is signed by at least
one of the "untrusted" attachments signers.

A cache of trusted and untrusted public keys is now held (replacing the
previous cache of `List<PublicKey>`.

Tests have been added to `NodeAttachmentServiceTest` to confirm that
an attachment query using an `EQUAL` statement will actually return
attachments that are signed by any of the keys passed into the query.

Confirming this allowed an `EQUAL` query to satisfy the search that
had to be done as part of this change.

`MockAttachmentStorage`'s query criteria was updated to better match
the real `NodeAttachmentService` implementation.

* CORDA-3018 Update cache name and kdoc on `isAttachmentTrusted`

* CORDA-3018 Verify that chains of trust do not occur

* CORDA-3018 Switch keys around to improve chain of trust tests

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.

dc179d4ea1 ENT-3057: Log hibernate warns and errors in different log (#4889)
* ENT-3057: Log hibernate warns and errors in different log

If a hibernate error occurs (deadlock, for example) that would cause a flow to be sent to the hospital, hibernate logs the warnings and errors before we do. This results in duplication in the logs, and pollutes the log. To solve this, we create a new log appender named diagnostic-{node-name}.log and log any org.hibernate messages of warn and above to that file. This way, messages are not lost, which means that the information can be retrieved if need be.

* Corrected indentation of comment (changed tab to space)

* Updated node-administration document to mention diagnostic logging change

* Fixed integration test. It was breaking because it was fetching the first log file in the folder, assuming there would be only one. This assumption is now invalid because the diagnostic log file that was introduced. Two tests were found that used similar logic to find a log file to examine, hence both were corrected to look for log files beginning with "node"

* Updated documentation as per review comments.
