Disable jinja debug output by default?

[benkozi]

Following uwtools integration, the workflow generation log is quite large now, and the process to generate the workflow takes a bit longer.

13M Apr 16 22:00 log.generate_FV3LAM_wflow

There appears to be some jinja debugging flag turned on? Miles of dereferencing statements:

...
root                   DEBUG    [dereference]         memory: 120G
root                   DEBUG    [dereference]         nodes: 1
root                   DEBUG    [dereference]         tasks_per_node: 1
root                   DEBUG    [dereference]         walltime: 00:30:00
...

I'm wondering if the longer runtime is related to this as well. The log is a bit much to digest now. Would we want to turn off this debug output by default?

Expected behavior

• Reduce log file size by limiting debug output.

Current behavior

• A lot of debug output that is mostly irrelevant to users unless debugging jinja.

Machines affected

• Current SRW develop branch.

Steps To Reproduce

• Generate a workflow.

@benkozi I believe this is happening because when I initially set up logging for generate_workflow I used the root logger rather than a dedicated logger object, which isn't best practice. Unless you plan to work on this you can assign me to fix it.

@mkavulich - I was hoping to look into it sometime, but I don't have any immediate plans. I'll assign to you. However, if you can't fit it in, let me know! Thanks.

As far as implementation goes, I was thinking it would be possible to do:

logging.getLogger("<jinja logger name>").setLevel(logging.INFO)

...or something. It might make sense to have a separate logging configuration parameter for jinja. Your approach could very well work too since debug would then only be set on the dedicated logger object.

Just wanted to check in on this issue and see if anyone still plans to work on it?

@gspetro-NOAA - No plans that I'm aware of.
