====== Deadline Basic ======

  * Deadline is a render manage application, it needs to install on all render client and all render slave and also the main deadline database server machine.
  * Deadline needs all machine can access a common network shared drive, one for all project, one for its repo which holds all the config and setting and tools under Deadline.
  * The "Deadline Repo" location is important,
    * under its repo/, it has
      * repo/api/python: for use python to control the whole deadline system and its network
      * repo/settings: connection.ini contains all the server info, like IP address, database info
  * There are several applications under it to form the Deadline system
    * Deadline Monitor: the overview list app to view and submit job in one location
      * Tool (check Super user mode) > Configure Repository Option > web service settings : shows it listening port for web RESTful api info

====== Python Scripting for Deadline ======

  * command in windows <code dos>
cd "c:\Program Files\Thinkbox\Deadline10\bin"
deadlinecommand.exe --version

REM get job detail and put into text
"D:\App\Deadline\bin\deadlinecommand.exe" -getjob 5cb6d7a04a99da2b84ad7cbe > d:\zTmp\result.txt

REM get slave names of a pool, return a list of slave machine names
"D:\App\Deadline\bin\deadlinecommand.exe" -getslavenamesinpool movie_nuke Assigned

REM job list
"D:\App\Deadline\bin\deadlinecommand.exe" -getjobsfilter username=tester
</code>

  * Python can be used for commanding the Deadline system, also can be used to Post-render/Pre-render script for triggering under render job events

====== Get Submission Info ======
  * mel process (SubmitMayaToDeadline.mel)
    - submit job label (9163 line) > SetupSubmission()
    - submit job label (next to Pipeline tool) @ 10743 > DeadlineSubmitterOnOk() > SetupSubmission()
    

  * for commandline
<code python>
# get deadline cmd exe path
dl_cmd = os.path.normpath( os.path.join(os.environ['DEADLINE_PATH'], 'deadlinecommand.exe') )

# use deadline cmd to get deadline system info
cmd = r'"{0}" -JSON -GetSubmissionInfo Pools Groups MaxPriority TaskLimit UserHomeDir RepoDir:submission/Maya/Main RepoDir:submission/Integration/Main'.format(dl_cmd)

# note: the original mel code, put " 2> nul" at the end of the cmd, which means no err output, and only 1st output/the result to the string. 
# so they don't need 2 variable like bellow to catch the return values.

info=subprocess.Popen(cmd,stdout=subprocess.PIPE, stdin=subprocess.PIPE, stderr=subprocess.PIPE)
out, err = info.communicate()
exitcode = info.returncode

# read data
import json
dl_data = json.loads(out)
deadlineSubmissionInfo=dl_data['result']

# pool list
pool_list = deadlineSubmissionInfo['Pools']

  * for existing maya deadline scene, the attribute is stored at defaultRenderGlobals <code python>
# for existing deadline scene
cmds.getAttr('defaultRenderGlobals.DeadlineMayaRepoPath')
# all the attribute saving is at SavePersistentDeadlineOptions() in mel
</code>
  * other maya info <code python>
# current renderer
renderer = cmds.getAttr('defaultRenderGlobals.currentRenderer') # arnold

        frameList = "{0}-{1}".format(frameList, toFrame)
        if byFrame > 1:
            frameList = "{0}x{1}".format(frameList, byFrame)
