Ref PHI2149. This provides the trivial Query class required for the daemons to publish Almanac Interface transactions.

(Publishing these doesn't do anything interesting, but currently leaves an error in the daemon logs.)

• Stopped the daemons.
• Edited the port of an Interface in Almanac.
• Ran bin/worker execute --active --class PhabricatorApplicationTransactionPublishWorker to publish the transaction.
  • Before: fatal on missing class, "Unable to load query for transaction object...".
  • After: transaction publishes cleanly.
