file_cache is unavailable when using oauth2client >= 4.0.0

[bivald]

This is related to #294

After upgrading google-api-python-client and oauth2client I get:

Oct 23 11:26:30 admin [11:26:30][WARNING] googleapiclient.discovery_cache init.py:autodetect:44 | file_cache is unavailable when using oauth2client >= 4.0.0#012Traceback (most recent call last):#12 File "/usr/share/python/.../local/lib/python2.7/site-packages/googleapiclient/discovery_cache/init.py", line 41, in autodetect#012 from . import file_cache#012 File "/usr/share/python/..../local/lib/python2.7/site-packages/googleapiclient/discovery_cache/file_cache.py", line 41, in #12 'file_cache is unavailable when using oauth2client >= 4.0.0')#012ImportError: file_cache is unavailable when using oauth2client >= 4.0.0

I know that it was added to add oauth2client support (which I appreciate) and from what I can see doesn't actually abort any action - but would it be possible to remove the WARNING as well - or is it meant as a future todo?

It's not a huge issue, but possibly confusing to others - not to mention my eyes stopping at it every time I view any logs or monitoring.

You can silence this the same way you can silence any other log using the standard library logging infrastructure:

import logging

logging.getLogger('googleapicliet.discovery_cache').setLevel(logging.ERROR)

[bivald]

Of course you can! I apologize, I blame the lack of coffee for my ignorance.

[theacodes]

No worries. :)

Are we sure that this is that simple? I have a project that I'm getting reports of seizing/crashing/weirdness with and I'm seeing these all over the log (no other issues):

2016-12-08 20:11:27,816 [googleapiclient.discovery_cache WARNING] file_cache is unavailable when using oauth2client >= 4.0.0
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/googleapiclient/discovery_cache/__init__.py", line 41, in autodetect
    from . import file_cache

    'file_cache is unavailable when using oauth2client >= 4.0.0')
ImportError: file_cache is unavailable when using oauth2client >= 4.0.0

These are ImportErrors, not just mere log verbosity. Thoughts?

[dsoprea]

It's worth mentioning that my version reference to google-api-python-client hasn't changed in over 2.5 years. I can't fathom why I haven't seen this error before and why it appears to be an issue now. But, it does appear to be an exception which must be disrupting something whether it's specifically related to my user's issue or something silent from the logs is responsible for that.

[theacodes]

@dsoprea if you silence the logs as above, do you still see the stacktrace?

[dsoprea]

@jonparrott I've asked. Thanks.

[xmedeko]

I apologize to comment on closed issue, but is there any performance penalty when the file_cache is not used with oauth2client 4.0.0? I.e. should I keep the oauth2client 3.0.0 or may I safely upgrade and ignore the warning? Thanks.

It seems to be the better way to silence this error, if one does not care about the cache, is to simply specify cache_discovery=False when performing discovery.build() -- this avoids the broken code path.

[WiliTest]

maxrp solution worked (python3.6) for most logging message: discovery.build('drive', 'v3', http=http, cache_discovery=False)

but I also needed to set the logging level of the googleapiclient.discovery using jonparrott proposition:
logging.getLogger('googleapiclient.discovery').setLevel(logging.CRITICAL)

[sendvibe]

jonparrott's answer almost worked for me.... you just have to fix the typo:

import logging
logging.getLogger('googleapiclient.discovery_cache').setLevel(logging.ERROR)

[mohitjoshi155]

file_cache is only supported with oauth2client<4.0.0
i am getting this error still

[sabuhigr]

init: file_cache is only supported with oauth2client<4.0.0

Still getting error.

[mabusdogma]

Still... still getting this error

[rnag]

Same.. please fix. Tuning down error log messages is a workaround rather than a fix.

[trizko]

For anyone landing on this issue in 2023, maxrp's solution from 2016 still works, setting cache_discovery=False:

from googleapiclient.discovery import build

client = build('drive', 'v3', cache_discovery=False)
