[GitHub] [buildstream] BenjaminSchubert opened a new pull request #1447: Completely remove the pipe between the parent and the child subprocess

BenjaminSchubert opened a new pull request #1447:
URL: https://github.com/apache/buildstream/pull/1447


   This will improve messaging between both and remove some contention on IO in the main process.
   
   I have looked at generated log files from the build, and could not spot errors, If someone else could have a look, it would be much appreciated.

   I concur, I stared the patch quite hard in the face and it appears correct to me.
   
   I am still a little curious about how success/fail/error status of child jobs is communicated in the absence of our pipe, but this appears to have all changed in the main previous patch which moves to a threaded scheduler, so it is irrelevant here.

   This is now done by letting exceptions propagate, since we are in the same process :) Indeed changed before.
