* perf_cache_resolving: Squashed 'json/' changes from 9208016..0b657e8 Need to preserve backwards compat for RefResolvers without the new methods. Pass in caches instead of arguments. I give up. Not deprecating these for now, just not used internally. Fix base_uri backwards compatibility. Er, green doesn't work on 2.6, and make running right out of a checkout easier. Wrong docstring. Add back assertions for backwards compat. Wait wat. Remove insanity. Probably should combine these at some point, but for now move them. Really run on the installed package. Begone py.test. Remove 3.3, use pip for installs, use green here too. lxml-cffi is giving obscure errors again. Fix a non-type in the docs. Switch to vcversioner, use repoze.lru only on 2.6, and add extras_require for format. Run tests on the installed package. Newer tox is slightly saner. It's hard to be enthusiastic about tox anymore. Use lru_cache Remove DefragResult. Remove context manager from ref() validation. Perf improvements by using a cache. Add benchmark script. Fix test failures issue #158: TRY to speed-up scope & $ref url-handling by keeping fragments separated from URL (and avoid redunant frag/defrag). Conflicts: jsonschema/tests/test_benchmarks.py
jsonschema
jsonschema is an implementation of JSON Schema for Python (supporting
2.6+ including Python 3).
>>> from jsonschema import validate
>>> # A sample schema, like what we'd get from json.load()
>>> schema = {
... "type" : "object",
... "properties" : {
... "price" : {"type" : "number"},
... "name" : {"type" : "string"},
... },
... }
>>> # If no exception is raised by validate(), the instance is valid.
>>> validate({"name" : "Eggs", "price" : 34.99}, schema)
>>> validate(
... {"name" : "Eggs", "price" : "Invalid"}, schema
... ) # doctest: +IGNORE_EXCEPTION_DETAIL
Traceback (most recent call last):
...
ValidationError: 'Invalid' is not of type 'number'Features
- Full support for Draft 3 and Draft 4 of the schema.
- Lazy validation that can iteratively report all validation errors.
- Small and extensible
- Programmatic querying of which properties or items failed validation.
Release Notes
- A simple CLI was added for validation
- Validation errors now keep full absolute paths and absolute schema
paths in their
absolute_pathandabsolute_schema_pathattributes. Thepathandschema_pathattributes are deprecated in favor ofrelative_pathandrelative_schema_path.
Note: Support for Python 3.2 was dropped in this release, and installation now uses setuptools.
Running the Test Suite
If you have tox installed (perhaps via
pip install tox or your package manager),
runningtox in the directory of your source checkout will
run jsonschema's test suite on all of the versions of
Python jsonschema supports. Note that you'll need to have
all of those versions installed in order to run the tests on each of
them, otherwise tox will skip (and fail) the tests on that
version.
Of course you're also free to just run the tests on a single version
with your favorite test runner. The tests live in the
jsonschema.tests package.
