Nested chains not running

[davidgrayston]

We are having problems running chains that call other chains. I believe this is because the ConsoleEvents::TERMINATE event is only fired once, which means the CallCommandListener only calls the top level chains in the ChainQueue.

I have updated the code to call commands directly rather than add them to the ChainQueue as this fixes the issue, however, it doesn't seem to be the correct approach.

I think you will have a better understanding of the issue and may be able to get this working with the CallCommandListener processing ChainQueue.

Here is an example of chains being nested:
drupal test:main

chain-test-main.yml

command:
  name: test:main
  description: 'Example of a chain calling another chain with placeholders'
commands:
  - command: test:child
    options:
      placeholder:
        - 'project:%{{project|main-project}}'
        - 'directory:main-dir'

chain-test-child.yml

command:
  name: test:child
  description: 'Example of chain that is called by another chain'
commands:
  - command: exec
    arguments:
      bin: 'echo "This is a test: Project:%{{project|foo}} Directory:%{{directory|bar}}"'
