No output, possible sdt stream confusion

Hi,

I am creating a plugin for Arnold’s maketx. Everything works, except I don’t get any output from the process.
E.g. maketx --invalidargument fails, but I don’t see anything in the log.
Running it in cmd shows the correct output.
Digging further I discovered that maketx prints all its errors to the stdout. Is this why deadline is not showing it? Can I change this behaviour?

Hello!

We might need some more information on this issue. The render logs would helpful here which failed to write the output. You can either upload the logs here in the forum or if anything sensitive feel free to open a ticket with us on (https://awsthinkbox.zendesk.com/).

Regards
Karpreet

Hi Karpreet,

You can find 4 logs in the attached zip. A success and a fail from deadline, then running the same commands from a cmd.
I found that even when maketx executes successfully I don’t have any output from it in the DL logs.
dl_maketx_logs.zip (4.8 KB)

How are you starting MakeTx in your plugin? The Deadline Worker should be capturing all the stdout.

Hi Justin,

This is a simple plugin, there is nothing special. Here is the WIP code.
MakeTx.py (8.7 KB)

It’s not helpful but that should be working so far as I can tell. We know the executable is running and we know that Deadline is catching the exit code.

If the output is actually going to STDOUT all that should be coming through. If you submit a CommandLine job that runs maketx.exe does that properly capture the output?

I tried it through CommandLine, but no output here either. You can see the log below.

So what is the difference between DL running the executable through the CommandLine plugin, and me running it in a cmd window?
These maybe?

Well, running the executable through the commandline plugin gets the possibility of the newly built plugin having issues out of the way. If maketx is indeed outputting to stdout we should have chatter in the CommandLine plugin logs.

I’m not sure how it’s different from the output you’re getting from the cmd window - those options you’ve highlighted should have stdout and stderr being redirected to the Worker’s logging. (Stdout Redirection Enabled: True should be doing this based on the code I’m reading).

Where’d you find the info about maketx outputting to stdout? Maybe there’s a caveat there I can’t think of?

I was running it from python with subprocess.Popen() when I found it only prints to stdout.

And I may be onto something. I can get the same result as through deadline if I run the following script.

import subprocess

args = r'"C:\Users\daniel.asztalos\AppData\Local\limes_da_sites\studio1\pkgs\0-dev-package\mtoadeploy\4.0.4.2\maya-2019\bin\maketx.exe" -invalidargument'


CREATE_NO_WINDOW = 0x08000000
CREATE_NEW_PROCESS_GROUP = 0x00000200
DETACHED_PROCESS = 0x00000008
creationflags = CREATE_NO_WINDOW | CREATE_NEW_PROCESS_GROUP | DETACHED_PROCESS

p = subprocess.Popen(args, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True, creationflags=creationflags)
stdout, stderr = p.communicate()

print p.returncode
print "----------------stdout----------------"
print stdout
print "----------------stderr----------------"
print stderr

output:

1
----------------stdout----------------

----------------stderr----------------

But if I remove the DETACHED_PROCESS from the flags, runs as expected:

1
----------------stdout----------------

                             the custom catalog paths.

----------------stderr----------------

I’m not sure what to do with this information yet… Is there a way, to remove the DETACHED_PROCESS flag when running through DL?

I don’t expect we’re letting the process break off into it’s own console:
https://docs.python.org/3/library/subprocess.html#subprocess.DETACHED_PROCESS

I have seen problems with output buffering before (for example, Python itself usually needs a “-u” flag when running inside of Deadline). I checked the maketx flags and don’t see anything about the output handling there.

From the commented out parts of your code, might be worth re-enabling standard output handling just in case

    def InitializeProcess(self):
        self.SingleFramesOnly = False
        self.PluginType = PluginType.Simple
        # self.StdoutHandling = True    # <-- This one should only be for handler, but may be worth it anyway

        # self.HideDosWindow = False
        # self.CreateNewConsole = True

The others don’t exist (or at least aren’t documented). Docs are here:
https://docs.thinkboxsoftware.com/products/deadline/10.1/2_Scripting%20Reference/class_deadline_1_1_plugins_1_1_deadline_plugin.html

We use .net Core’s C# Process object to start applications, so there are probably a few Python-centric things that won’t apply here unfortunately.

Ran a quick test by installing the maketx from C4D Arnold version (C4DtoA-2.6.1.5-win-R21.exe specifically) on Deadline 10.1.9.2 and it seems to have worked:
