Hello, devs, Could someone point me where I go wrong in the following? My Differentials constantly fail to CI with the messages like this one: exception 'PhabricatorWorkerPermanentFailureException' with message 'Lease "PHID-DRYL-sydepw7hjxlnim325sdu" never activated.' in /opt/phabricator/src/applications/harbormaster/step/HarbormasterLeaseWorkingCopyBuildStepImplementation.php:91 Stack trace: #0 /opt/phabricator/src/applications/harbormaster/worker/HarbormasterTargetWorker.php(70): HarbormasterLeaseWorkingCopyBuildStepImplementation->execute(Object(HarbormasterBuild), Object(HarbormasterBuildTarget)) #1 /opt/phabricator/src/infrastructure/daemon/workers/PhabricatorWorker.php(123): HarbormasterTargetWorker->doWork() #2 /opt/phabricator/src/infrastructure/daemon/workers/storage/PhabricatorWorkerActiveTask.php(171): PhabricatorWorker->executeTask() #3 /opt/phabricator/src/infrastructure/daemon/workers/PhabricatorTaskmasterDaemon.php(22): PhabricatorWorkerActiveTask->executeTask() #4 /opt/libphutil/src/daemon/PhutilDaemon.php(219): PhabricatorTaskmasterDaemon->run() #5 /opt/libphutil/scripts/daemon/exec/exec_daemon.php(131): PhutilDaemon->execute() #6 {main} Examples: https://phabricator.haskell.org/harbormaster/build/50735/ https://phabricator.haskell.org/harbormaster/build/51066/ https://phabricator.haskell.org/harbormaster/build/51616/ I googled this and found a similar topic on Phab's bug tracker: https://secure.phabricator.com/T10982 Not particularly helpful 'cause I don't really understand the internals of Phab. This started to happen roughly when I moved my ghc hacking setup to a new hardware this summer. Maybe, that's connected. Also, what suspicious is that `arc diff` tries to push changes in master right away, so I have to pass --skip-staging. This wasn't the case before, I believe. -- Best, Artem Best, Artem
