- a length check should come before the access, so you can verify
whether the access will succeed.
- Also removed some tests which can't work, due to the filter
changes. In fact, a lot of these tests should probably be
removed or changed if we want to disallow running
apply_common_filters() on plain dicts. They will often
coincidentally still succeed though, so I left them in.
datetimes: I'd converted the object property instead of the
filter value! :-P
Also, I fixed filter validation: it was checking for exact types
of the filter values and disallowing subtypes. This library
includes a datetime subtype named STIXdatetime, and this type
should be usable as a filter value too. So we need to allow
subtypes.
Timestamp properties can now be checked against filter values
which are either strings or datetime objects, using datetime
semantics (previously, it reduced to a string compare).
If a stix object property is datetime-valued and the filter
value is a string, the string is parsed to a datetime object,
rather than the other way around.
Filtering in the filesystem store now parses JSON dicts to
_STIXBase objects before applying the filters.
Due to the parsing change, bad JSON content can produce a
different kind of error, so I had to change one of the tests.
datastore test suite. Add a new test corpus file, located so
as to test the backward compatibility functionality of
FileSystemSource. Add a test to the suite which ensures that
this new file is found.
objects are searched for as ID-named json files in the type
directories, in addition to timestamp-named files in ID
directories.
Made a bugfix: fixed improper exception re-raises
Made an efficiency improvement: don't stat() files in
_get_matching_dir_entries() if no st_mode_test callable is given.
