== Program Name ==
makeDRPcont

== PCS stream-state ==
group: EventStream table: <database name> state: MakeDRPGif

== Description ==
makeDRPcont runs programs to generate the waveform image (snapshot) for the [[postproc:drp|Duty Review Page]] for new events. If the event magnitude is 2.5 or larger, a synopsis waveform image is also generated. The resulting images are then copied using scp to a configured list of remote destinations such as the Duty Review Page web server.

makeDRPcont runs a modified PCS loop:
  * queries for the next event in its assigned stream-state
  * if an event is found and is less than 7 days old, fork off a child process to handle that event
  * the parent program will not let more than 2 processes run; if necessary it waits for a child to finish before starting the next one. This is to minimize the load on wave servers for this task.
  * the parent process set the stream-state event result to 1 immediately.
  * the child process runs //snapGif// to generate the snapshot image.
  * if the event magnitude is 2.5 or greater, the child process runs //synopsgif// to generate the synopsis image.
  * the child process copies the resulting image files using scp to destinations listed in //targetURL.cfg//
  * the child process runs //cleanup// on the local and remote image directories to delete files more than 7 days old.
  * if no event is found, the parent program sleeps 30 seconds and repeats the loop
