Re: [HTCondor-users] Change submit parameter configuration knob with python bindings

[Josh Karpel <karpel@xxxxxxxx>]

Hi Kenyi,

It looks like htcondor.param is expecting you to pass in purely string expressions, and only does conversion on the way back out to you. In particular, this works:

In [1]: import htcondor                                                                                              Â

In [2]: htcondor.param.get("SUBMIT_GENERATE_CUSTOM_RESOURCE_REQUIREMENTS") Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â
Out[2]: True

In [10]: htcondor.param["SUBMIT_GENERATE_CUSTOM_RESOURCE_REQUIREMENTS"] = "false" Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â

In [11]: htcondor.param.get("SUBMIT_GENERATE_CUSTOM_RESOURCE_REQUIREMENTS") Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â
Out[11]: False

In [12]: type(htcondor.param.get("SUBMIT_GENERATE_CUSTOM_RESOURCE_REQUIREMENTS")) Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â
Out[12]: bool

I've noted this on a related ticket on our end (Âhttps://htcondor-wiki.cs.wisc.edu/index.cgi/tktview?tn=7658,4Â).

Note that since the key is already set, you probably don't want to use setdefault, since

In [2]: htcondor.param.setdefault("SUBMIT_GENERATE_CUSTOM_RESOURCE_REQUIREMENTS", "false") Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â
Out[2]: 'true'

(setdefault only sets if the key is not set, seeÂhttps://docs.python.org/3/library/stdtypes.html#dict.setdefault)

Hi,

I would like to change the following parameter that defaults to True:

SUBMIT_GENERATE_CUSTOM_RESOURCE_REQUIREMENTS = False

via python bindings, using HTCondor 8.9.7. htcondor.param should allow
for that, but it seems it only supports string values. Is this
correct? Is there any other way for setting this parameter?

>>> import htcondor
>>> htcondor.param.get("SUBMIT_GENERATE_CUSTOM_RESOURCE_REQUIREMENTS")
True
>>>
type(htcondor.param.get("SUBMIT_GENERATE_CUSTOM_RESOURCE_REQUIREMENTS"))
<type 'bool'>
>>>
htcondor.param.setdefault("SUBMIT_GENERATE_CUSTOM_RESOURCE_REQUIREMENTS", False)

  _Param.setdefault(_Param, str, bool)
