CORDA-2005: FinalityFlow has been made into an inlined flow to resolve issue with FinalityHandler (#4050)
FinalityHandler is insecure in that it is open to receive any transaction from any party.

Any CorDapp targeting platform version 4 or above is required use the new c'tors which take in FlowSession objects to the counterpart flow. This flow must subcall ReceiveFinalityFlow to receive and record the finalised transaction.

Old CorDapps (with target platform version < 4) will continue to work as previously. However if there are no old CorDapps loaded then the node will disable FinalityHandler.

Attachment Demo

This demo brings up three nodes, and sends a transaction containing an attachment from one to the other.

To run from the command line in Unix:

  1. Run ./gradlew samples:attachment-demo:deployNodes to create a set of configs and installs under samples/attachment-demo/build/nodes
  2. Run ./samples/attachment-demo/build/nodes/runnodes to open up three new terminal tabs/windows with the three nodes and webserver for BankB
  3. Run ./gradlew samples:attachment-demo:runRecipient, which will block waiting for a trade to start
  4. Run ./gradlew samples:attachment-demo:runSender in another terminal window to send the attachment. Now look at the other windows to see the output of the demo

To run from the command line in Windows:

  1. Run gradlew samples:attachment-demo:deployNodes to create a set of configs and installs under samples\attachment-demo\build\nodes
  2. Run samples\attachment-demo\build\nodes\runnodes to open up three new terminal tabs/windows with the three nodes and webserver for BankB
  3. Run gradlew samples:attachment-demo:runRecipient, which will block waiting for a trade to start
  4. Run gradlew samples:attachment-demo:runSender in another terminal window to send the attachment. Now look at the other windows to see the output of the demo
