I think it's cleaner to use current_app.config instead of os.environ (see usage in other places of views.py)
this config is populated here:
openeo-python-driver/openeo_driver/server.py
Lines 19 to 23 in 5c1e927
at this place you could get the values from
os.environ. I would just avoid using os.environ in views.py directly

expiration timestamp return value can still be int at this point I think

regarding the avoiding of os.environ not of above: I think you can just do @mock.patch.dict(app.config, {'SIG... here (app object is already available at this point)

New errors in this file have first to be defined through https://github.com/Open-EO/openeo-api/blob/master/errors.json

in the mean time, you can just raise a generic exception:
raise OpenEOApiException(
status_code=410,
code="FileExpired",
message="File '{file}' has expired".format(file=filename)"

Interesting suggestion from Open-EO/openeo-api#379 (comment):
raise it with something like:
raise OpenEOApiException(
status_code=410,
code="AssetLinkExpired",
message="Batch job asset link has expired. Request the batch job results again for fresh asset links" ,
)

FYI: Open-EO/openeo-api#380 is now merged in draft and the newly introduced error is so you could already adapt that error code |
|
is that bump of the openeo_driver/specs/openeo-api/0.4 submodule intentional? |
