spyne 2.12.10

A transport and architecture agnostic rpc library that focuses on exposing public services with a well-defined API.

Package Documentation


Spyne aims to save the protocol implementers the hassle of implementing their own remote procedure call api and the application programmers the hassle of jumping through hoops just to expose their services using multiple protocols and transports.



  • IpAddress types now support PostgreSQL’s PGInet.
  • Drop trial for twisted tests and switch to pytest-twisted.
  • _safe_set now returns True on success so that protocols can react accordingly.
  • *DictDoc now logs properly whether a value is discarded or passed to the deserialized instance.
  • Minor bug fixes here and there.


  • Make DateTime handle unicode date format strings for Python 2.
  • Fix idle timer not starting on connectionMade for MessagePackTransportBase


  • Not beta anymore. Woo!
  • Made ServiceBase subclasses reusable
  • Implemented class customization via __getitem__.
  • Fixed an ImportError running Python 3.4 under Pydev using PyCharm. (Eclipse still has issues, see issue #432. Any help would be much appreciated)
  • Fixed DateTime corner case with μs values between 999995 and 999999.
  • Help misguided user code that returns an int for a string type by implicitly yet not-so-silently converting the int/long to str.
  • Fixed *Cloth sometimes getting stuck repr()’ing passed instance.
  • Fixed SimpleDictDocument confusing a missing value and an empty value for array types. When the client wants to denote an empty array, it should pass array_field=empty. Normally it passes something along the lines of: array_field[0]=Something&array_field[1]=SomethingElse.
  • Split MessagePackServerBase to MessagePackTransportBase and MessagePackServerBase. No API was harmed during this change.
  • Implement optional idle timeout for MessagePackTransportBase.
  • Add support for PGObjectJson, PGObjectXml and PGFileJson to sql table reflection.
  • log_repr now consults NATIVE_MAP as a last resort before freaking out.
  • Removed some dead code.


  • Thanks to issue #446 we noticed that in some cases, SOAP messages inside HTTP requests got processed even when the request method != ‘POST’. This got resolved, but you should check whether this is the case in your setup and take the necessary precautions before deploying Spyne.


  • Many bugs fixed very quick.


  • XmlObject: Support for attribute_of is removed.
  • NullServer now supports async.
  • XmlCloth was rewritten while less sleep-deprived.
  • ProtocolBase now also implements serializing primitives to unicode.
  • Add initial support for input polymorphism to XmlDocument (parsing xsi:type). It’s an experimental feature.
  • Add output polymorphism for all protocols. It’s off-by-default for XmlDocument and friends, on-by-default for others.
  • Add stub implementation for SOAP 1.2
  • Add initial implementation for SOAP 1.2 Faults.
  • Remove the deprecated interface argument to Application.
  • HierDictDocument’s broken wrapped dict support was fixed. Even though this is supposed to break compatibility with 2.11, virtually no one seems to use this feature. Only now it’s mature enough to be set on stone. Let us know!
  • We now validate kwargs passed to @rpc. Be sure to test your daemons before deploying for production, because if you got leftovers, the server will refuse to boot!
  • It’s now forbidden (by assert) to inherit from a customized class.
  • It’s also forbidden (by convention) to instantiate a customized class. Don’t do it! The warning will be converted to an assert in the future.


  • Experimental Python 3 Support for all of the Xml-related (non-Html) components.

  • Add support for altering output protocol by setting ctx.out_protocol.

  • Add returning ctx.out_string support to null server (The ostr argument).

  • Add support for XmlData modifier. It lets mapping the data in the xml body to an object field via xsd:simpleContent.

  • Remove deprecated JsonObject identifier. Just do a gentle s/JsonObject/JsonDocument/g if you’re still using it.

  • SQLAlchemy: Implement storing arrays of simple types in a table.

  • SQLAlchemy: Make it work with multiple foreign keys from one table to another.

  • SQLAlchemy: Implement a hybrid file container that puts file metadata in a json column in database and and file data in file system. Fully supported by all protocols as a binary File.Value instance.

  • Implement an Xml Schema parser.

  • Import all model markers as well as the @rpc, @srpc, @mrpc, ServiceBase and Application to the root spyne package.

  • Implement JsonP protocol.

  • Implement SpyneJsonRpc 1.0 protocol – it supports request headers.

    Sample request: {"ver":1, "body": {"div": [4,2]}, "head": {"id": 1234}} Sample response: {"ver":1, "body": 2}

    Sample request: {"ver":1, "body": {"div": {"dividend":4,"divisor":0]}} Sample response: {"ver":1, "fault": {"faultcode": "Server", "faultstring": "Internal Error"}}}

  • Steal and integrate the experimental WebSocket tranport from Twisted.

  • Support Django natively using spyne.server.django.DjangoView and spyne.server.django.DjangoServer.

  • It’s now possible to override the JsonEncoder class JsonDocument uses.

  • Remove hard-coded utf-8 defaults from almost everywhere.

  • Remove hard-coded pytz.utc defaults from everywhere. Use spyne.LOCAL_TZ to configure the default time zone.

  • As a result of the above change, datetime objects deserialized by Spyne are forced to the above time zone during soft validation (nothing should have changed from the user code perspective).

  • Add default_factory to ModelBase customizer. It’s a callable that produces default values on demand. Suitable to be used with e.g. lambdas that return mutable defaults.

  • New spyne.util.AttrDict can be used for passing various dynamic configuration data.

  • child_attrs can now be passed to the ComplexModelBase customizer in order to make object-specific in-place customizations to child types.

  • Add mapper between Django models and spyne.util.django.DjangoComplexModel types.

  • Spyne now tracks subclasses and adds them to the interface if they are in the same namespace as their parent.

  • Simple dictionary protocol’s hier_delim default value is now ‘.’

  • Fixes support for XmlAttributes with max_occurs>1 referencing the same ‘attribute_of’ element in a ComplexModel subclass.

  • Renders spyne.model.File as twisted.web.static.File when using HttpRpc over TwistedWebResource. This lets twisted handle Http 1.1-specific functionality like range requests.

  • Many, many, many bugs fixed.


  • Fix wsdl rendering in TwistedWebResource.
  • Fix http response header propagation in TwistedWebResource.
  • Fix handling of fractions in microsecond values.
  • Fix spyne.util.get_validation_schema()


  • Fix total_seconds quirk for Python 2.6.
  • Turn off Xml features like entity resolution by default. This mitigates an information disclosure attack risk in services whose response contain some fragments or all of the request. Also prevents DoS attacks that make use of entity expansion. See for more info.
  • Drop Python 2.5 support (It wasn’t working anyway).


  • Fix Unicode losing pattern on re-customization
  • Fix Duration serialization, add a ton of test cases.
  • Fix binary urlsafe_base64 encoding.
  • Fix arbitrary exception serialization.
  • Fix some doc errors.


  • Fix logic error in wsdl caching that prevented the url in Wsdl document from being customized.
  • Fix dictdoc not playing well with functions with empty return values.


  • Fix exception serialization regression in DictDocument family.
  • Fix xml utils (and its example).


  • Fix default value handling in HttpRpc.
  • Fix invalid document type raising InternalError in DictDocument family. It now raises ValidationError.
  • HttpRpc: Fix ByteArray deserialization.
  • HttpRpc: Fix many corner cases with Arrays.
  • Fix Csv serializer.
  • Fix Mandatory variants of Double and Float inheriting from decimal.


  • Fix handling of spyne.model.binary.File.Value with just path name.
  • Fix decimal restrictions (some more).
  • Make user code that doesn’t return anything work with twisted server transport.


  • Add validation tests for HierDictDocument and fix seen issues.
  • Add validation tests for FlatDictDocument and fix seen issues.
  • Clarify Json and Http behavior in relevant docstrings.
  • Fix Python2.6 generating max_occurs=”inf” instead of “unbounded” sometimes.


  • Fix ByteArray support accross all protocols.
  • Fix namespaces of customized simple types inside XmlAttribute not being imported.


  • Fix confusion in Decimal restriction assignment.
  • Fix classmethod calls to ProtocolBase.
  • Fix schema generation error in namespaced xml attribute case.


  • Returning twisted’s Deferred from user code is now supported.
  • You can now set Http response headers via ctx.out_header when out_protocol is HttpRpc.
  • lxml is not a hard requirement anymore.
  • XmlDocument and friends: cleanup_namespaces is now True by default.
  • XmlDocument and friends: Added encoding and pretty_print flags that are directly passed to lxml.etree.tostring().
  • XmlDocument and friends:’attribute_of’ added to ModelBase to add attribute support for primitives. This is currently ignored by (and mostly irrelevant to) other protocols.
  • XmlDocument and friends: Attribute serialization is working for arrays.
  • Add support for exposing existing whose source code via the _args argument to the srpc decorator. See the existing_api example for usage examples.
  • Add Streaming versions of Pyramid and Django bridge objects.
  • Remove destructor from MethodContext. Now transports need to call .close() explicitly to close object and fire relevant events.
  • Application event ‘method_context_constructed’ was renamed to 'method_context_created'.
  • Application event ‘method_context_destroyed’ was removed. The 'method_context_closed' event can be used instead.
  • SQLAlchemy integration now supports advanced features like specifying indexing methods.
  • The object composition graph can now be cyclic.
  • Integers were overhauled. Now boundary values of limited-size types are accessible via Attributes._{min,max}_bounds.
  • We now have six spatial types, Point, LineString and Polygon along with their Multi* variants.
  • The deprecated ProtocolBase.set_method_descriptor function was removed.
  • It’s now possible to override serialization in service implementations. You can set ctx.out_document to have the return value from user funtion ignored. You can also set ctx.out_string to have the ctx.out_document ignored as well.
  • Added as_timezone support to DateTime. It calls .astimezone(as_time_zone).replace(tzinfo=None) on native values.
  • Added YAML support via PyYaml.
  • Split dict logic in DictDocument as HierDictDocument and FlatDictDocument.
  • Complete revamp of how DictDocument family work. skip_depth is replaced by richer functionalty that is enabled by two flags: ignore_wrappers and complex_as.
  • Added cookie parsing support to HttpRpc via Cookie.SimpleCookie.
  • Moved {to,from}_string logic from data models to ProtocolBase. This gives us the ability to have more complex fault messages with other fault subelements that are namespace-qualified without circular dependency problems - Stefan Andersson <>
  • DictDocument and friends: ignore_wrappers and complex_as options added as a way to customize protocol output without hindering other parts of the interface.
