Chris Lenk b4a0a9ea10 Remove six dependency (backwards breaking)
We've already removed Python 2 from our test harness, but this removes
all python 2 compatibility code left in.

Emmanuelle Vargas-Gonzalez 489970718f WIP: changes to graph_similarity

Michael Chisholm 0dd6462d60 Add some unit tests which try to version marking-definitions. 2021-01-28 23:02:23 -05:00
Michael Chisholm c74d06aadc Improve versioning.new_version() to better handle custom objects
and dicts, and add better raised exception types if versioning
couldn't be done.  I changed workbench monkeypatching a bit, to
copy some class attributes over to the workbench wrapper
class-like callables, since some code expected those attributes
to be there (e.g. the versioning code).

Michael Chisholm 5aadf1ae91 Add some unit tests for attempting to change ID contributing
properties of a 2.1 SCO with UUIDv5 ID, when creating a new
version.
2021-01-20 19:16:22 -05:00
Michael Chisholm fe2330af07 Improve is_sdo() et al utility functions with respect to
dict/mapping values: do a simple verification of the value's
STIX version, not just its type.  Added a lot more unit tests to
test behavior on dicts.  To make the implementation work, I had
to move the detect_spec_version() function out of the parsing
module and into utils.  So that required small changes at all
its previous call sites.
2021-01-20 16:59:39 -05:00
Michael Chisholm f88fba6751 Change the stix2 class map structure to be keyed at the top
level with STIX versions in the same format as is used everywhere
else in the API: "X.Y", as opposed to the "vXY" format used by
the version-specific python packages.  This eliminates all of
the awkward conversion from public API format to "vXX" format.

Also a little bit of code rearranging in the registration module
to ensure that some STIX 2.1-specific checks are done whether
version 2.1 is given explicitly or is defaulted to.

In the same module I also added a missing import of
stix2.properties, since my IDE was claiming it could not find a
function from that module.

Emmanuelle Vargas-Gonzalez 85c14d1502 all changes from add-trailing-commas v2.0.2 2021-01-13 17:52:15 -05:00
Michael Chisholm f51e309775 Refactor stix2.parsing into more focused modules:
- stix2.registry, which contains the class mapping structure
  and code for scanning stix2 modules for its initial population
- stix2.registration, which contains code used to register custom
  STIX types with the registry
- stix2.parsing, which contains code for creating instances of
  registered stix2 classes from raw dicts.

This is intended to reduce circular import problems, by giving
dependent code the ability to import a module which has exactly
the functionality it needs, without pulling a lot of other stuff
it doesn't need.  Fewer imports means less chance of an import
cycle.

* new graph_equivalence methods

* add notes

* add support for versioning checks (default disabled)

* new tests to cover graph equivalence and new methods

* added more imports to environment.py to prevent breaking changes

* variable changes, new fields for checks, reset depth check per call

* flexibility when object is not available on graph.

* refactor debug logging message

* new file stix2.equivalence.graph_equivalence.rst and stix2.equivalence.object_equivalence.rst for docs

* API documentation for new modules

* additional text required to build docs

* add more test methods for list_semantic_check an graphically_equivalent/versioning

* add logging debug messages, code clean-up

* include results as summary in prop_scores, minor tweaks

* Update __init__.py

doctrings update

* apply feedback from pull request

- rename semantic_check to reference_check
- rename modules to graph and object respectively to eliminate redundancy
- remove created_by_ref and object_marking_refs from graph WEIGHTS and rebalance

* update docs/ entries

* add more checks, make max score based on actual objects checked instead of the full list, only create entry when type is present in WEIGHTS dictionary

update tests to reflect changes

* rename package patterns -> pattern

* documentation, moving weights around

* more documentation moving

* rename WEIGHTS variable for graph_equivalence

this.  Fixed a typo in a 2.0 unit test (2.0 deduplicate() test).

Michael Chisholm 16a8c544ac Add a find_equivalent_patterns() function and unit tests, in case
a user wants a more efficient search capability.  (It is more
efficient than calling equivalent_patterns() over and over in a
loop, because it doesn't repeatedly re-canonicalize the search
pattern.)
