Michael Chisholm 3adf7800a8 Changed how filters work, with respect to datetime objects.
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.

Michael Chisholm 63166ab256 Add some backward-compatibility to filesystem store: versioned
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.

Michael Chisholm da13882eec Fix FileSystemSource.get() to not look for the latest version of
an object when markings are queried, since markings are not
versioned.
2018-11-27 15:24:08 -05:00
Michael Chisholm 2b983368e5 Fix an indexing error which caused FileSystemSource.get() to return
the oldest object instead of the newest.

Michael Chisholm 428a18ded2 Implemented clenk's suggested changes in multi-version filesystem
store:
- Use utils.get_type_from_id() instead of my own (I didn't know it
  was already there)
- Use dict-style instead of attribute-style access to get stix
  object properties
- Convert timezone-aware timestamps to UTC in _timestamp2filename()
  to ensure that different times always result in different
  filenames.

Also added a couple new tests for _timestamp2filename(), which
exercises the timezone conversion code.

Michael Chisholm 461e8bd5cb Removed the old FileSystemSource.query method. I'd renamed it
"query2" and forgot about it and left it there...

Michael Chisholm 0096835cfc Add multi-version support to the filesystem datastore.
Factored out the _is_marking() function from the memory datastore
module to utils so it can be reused, and changed both filesystem
and memory datastore modules to import and use it.

...now that MemorySource normalizes its data to python-stix2 objects.
2018-10-23 14:29:56 -04:00
Michael Chisholm cbe8d22d0a Added support to multi-version memory stores for markings. Also
added some more unit tests which test storing/retrieving markings
from the stores.

docstring.

Michael Chisholm d9f6a213c1 Fixed Memory source/sink/store so that it supports multiple versions
of objects.  Fixed several bugs too.
2018-10-15 18:02:49 -04:00
Michael Chisholm 5a0e102959 Modify docstring for apply_common_filters() to change what it
says are the required types for its parameters.  It gave
specific types (list and set), when really it worked with more
than just that (iterables).  And I certainly didn't only call
it with just lists and sets.

Chris Lenk f47809eaaf Add "contains" filter
This allows filtering on, for example, observed-data objects that
