      column on the profile activity page to link to the log files. This is
      imperfect, turns out we do not save the publicid in the CM history
      tables, so have lost the ability for public access to terminated slices
      (there is no way to look up a terminated slice by publicid). Admins can
      see them though, using the slice_uuid since red-dot is allowed to do
      that.

      Implement heartbeat/status reports in Frisbee. · 2be46ba4
      Mike Hibler authored
      There are three pieces here, a change to the frisbee protocol itself, an
      Emulab event component to get status back to the portal, and the surrounding
      infrastructure to make it all work.
      
      Frisbee heartbeat messages:
      
      Added a new message type to the frisbee protocol, "Progress". In theory it
      operates by having the server send a multicast progress request to its clients
      which includes an interval at which to report (or "just once") and an
      indication of what to report (nothing, progress summary, or full stats). The
      client then sends unicast "fire and forget" UDP replies according to that
      schedule. However, I took a shortcut for the moment and just added a command
      line option to the client to tell it to report a summary at the indicated
      interval (-H <interval>).  So the server never sends requests.
      
      This is implemented in the client by a fourth thread since I wanted it to
      operate independent of packet reception (which would cause clients to report
      in a highly synchronized fashion due to multicast). The server instance just
      logs progress reports into its log.
      
      This protocol addition should be fully backward compatible as both client and
      server ignore (but log) unknown messages.
      
      Emulab progress report events:
      
      When this is compiled in (-DEMULAB_EVENTS) and turned on (-E <server>), the
      frisbee server instances will send a FRISBEEPROGRESS event to the indicated
      event server for every progress report it receives (in addition to logging the
      events to its own log). Right now it will create an event with key/value pairs
      for the information in a client summary reply:
      
      TSTAMP is the client's time at which it sends the event. Could be used by the
      received to determine latency of the report if it cared (and if it assumed
      that the clocks are in sync). We don't care about this.
      
      SEQUENCE is the report number. Again, could be used by the receiver, in this
      case to detect loss, if it cared. We don't.
      
      CHUNKS_RECV is complete chunks that the client has received from the network.
      CHUNKS_DECOMP is chunks decompressed by the client.  BYTES_WRITTEN is bytes
      written to disk by the client.
      
      Any of the three can be used by the event receiver as an indication of life
      and/or progress. However, only the last would be a reasonable indicator of
      time remaining since it is the last (and slowest) phase of imaging. To
      estimate time remaining we could compare that value to the amount of
      uncompressed data that is in the image. This makes the sketchy assumptions
      that time for writes to the disk are uniform and that the number and distance
      of seeks is uniform, but it is better than a sharp stick in the eye.
      
      Emulab infrastructure:
      
      There is a new sitevar "images/frisbee/heartbeat" which can be set to a
      non-zero value to tell the frisbee MFS to fire off frisbee with -H <value>
      and thus make reports. The default value of zero means to not make reports.
      The tmcd "loadinfo" command sends this through via the HEARTBEAT=<value>
      param.
      
      REQUIRED A TMCD VERSION BUMP TO 41.

      Various tweaks to reservation UI: · 29258b2c

      * Allow start to be optional; means "now".
      
      * When selecting the current day, disable hours in the past.
      
      * Catch a few more form errors.
      
      * When editing, the start time might be in the past. Do not consider
        that an error, just pass it through since the backend is okay with
        it.
