6.2.0
^^^^^

Bug Fixes

* Fixes deployment failures when the image download is interrupted
  mid-stream while the contents are being downloaded. Previously
  retries were limited to only opening the initial connection.

* Fixes the short timeout retries interval, which was previously "5"
  seconds, to a length that will allow the agent to retry after a
  network interruption. The time between retries is now "10" seconds,
  and the number of retries are set to "9" to help ensure intermittent
  network outages do not cause recoverable failures.

* Fixes an issue with high cpu usage caused by ironic-python-agent
  greenthread eventlent implementation.

  Using eventlet.sleep(0.1) instead of eventlet.sleep(0) gives other
  processes of IPA more cpu time to run.

* Speeds up going from inspection to cleaning with fast-track
  enabled by caching hardware information between the steps.

* Fixes serializing exceptions originating from ironic-lib.
  Previously an attempt to do so would result in a "TypeError", for
  example: *Object of type 'InstanceDeployFailure' is not JSON
  serializable*.

* The size of the ESP partition created for software RAID has been
  increased from 128 MiB to 550 MiB. This change is in line with the
  recent diskimage-builder change (https://opendev.org/openstack
  /diskimage-builder/commit/7fd52ba84180b4e749ccf4c9db8c49eafff46ea8)
  as well as the guidance from the author of gdisk
  (https://www.rodsbooks.com/efi-bootloaders/principles.html).

* Fixes failure to detect a hung file download connection in the
  event that the kernel has not rapidly detected that the remote
  server has hung up the socket. This can happen when there is
  intermittent and transient connectivity issues such as those that
  can occur due to LACP failure response hold-downs timers in
  switching fabrics.
