Overview

"Suds" is a lightweight SOAP-based web service client for Python licensed under LGPL (see the LICENSE.txt file included in the distribution).

This is hopefully just a temporary fork of the original suds Python library project created because the original project development seems to have stalled. Should be reintegrated back into the original project if it ever gets revived again.

Forked project information

• Project site - http://bitbucket.org/jurko/suds
• Epydocs documentation - needs to be built from sources
• Official releases can be downloaded from:
  • BitBucket - http://bitbucket.org/jurko/suds/downloads
  • PyPI - http://pypi.python.org/pypi/suds-jurko

Original suds Python library development project information

• Project site - http://fedorahosted.org/suds
• Documentation - http://fedorahosted.org/suds/wiki/Documentation
• Epydocs - http://jortel.fedorapeople.org/suds/doc

For development notes see the HACKING.rst document included in the distribution.

Installation

Standard Python installation.

Here are the basic instructions for 3 different installation methods:

1. Using pip
   • Have the pip package installed.
   • Run pip install suds-jurko.
2. Using easy-install
   • Have the setuptools package installed.
   • Run easy_install suds-jurko.
3. From sources
   • Unpack the source package somewhere.
   • Run python setup.py install from the source distribution's top level folder.

Installation troubleshooting:

• If automated setuptools Python package installation fails (used in releases 0.4.1 jurko 5 and later), e.g. due to PyPI web site not being available, user might need to install it manually and then rerun the installation.
• Releases prior to 0.4.1. jurko 5 will fail if the distribute Python package is not already installed on the system.
• Python 2.4.3 on Windows has problems using automated setuptools Python package downloads via the HTTPS protocol, and therefore does not work correctly with PyPI which uses HTTPS links to all of its packages. The same does not occur when using Python version 2.4.4.

Release notes

version 0.6 (2014-01-24)

• Based on revision 712 (1e48fd79a1fc323006826439e469ba7b3d2b5a68) from the original suds Python library development project's Subversion repository.
  • Last officially packaged & released suds Python library version - 0.4.1.
• Supported Python versions.
  • Intended to work with Python 2.4+.
  • Basic sources prepared for Python 2.x.
  • For using Python 3 the sources first processed by the Python py2to3 tool during the setup procedure.
  • Tested in the following environments:
    • Python 2.4.3/x86, on Windows 7/SP1/x64.
    • Python 2.4.4/x86, on Windows 7/SP1/x64.
    • Python 2.7.6/x64, on Windows 7/SP1/x64.
    • Python 3.2.5/x64, on Windows 7/SP1/x64.
    • Python 3.3.3/x86, on Windows 7/SP1/x64.
    • Python 3.3.3/x64, on Windows 7/SP1/x64.
• Fixed sending HTTP request containing non-ASCII unicode data using Python 2.7.
  • Many thanks to mduggan1 and Alexey Sveshnikov for reporting the issue and suggesting patches.
• Fixed unicode data logging issue (contributed by Bouke Haarsma).
• suds.transport.Request object string representation cleaned up a bit - added a missing space before the URL to make it consistent with how all the other Request & Reply data is represented in such strings.
• Fixed issue with suds client failing to be create its default cache object (e.g. because a folder it needs is write protected) and thus preventing the client from being created without any chance for the user to specify an alternative cache.
  • The default client cache is now instantiated only if user does not explicitly specify some other alternate cache (or even None to disable the whole data caching system).
  • Many thanks to Arthur Clune for reporting the issue.
• Added explicit tests for URL parameters being passed as unicode or single-byte strings under Python 2 but only unicode strings under Python 3, and improved how such invalid parameter values are reported.
  • This behaviour matches urllib implementation differences between Python 3 and earlier Python interpreter versions.
  • Many thanks to Mesut Tasci for reporting a related issue and preparing the initial patch for it.
• Extra arguments used when making a web service operation call are now reported similar to how this is done for regular Python functions.
  • The extra argument error reporting may be disabled using the new extraArgumentErrors suds option.
  • Basic idea and the initial implementation for this feature contributed by Bouke Haarsma.
• Corrected a typo in the BuildError exception message.
• Removed partial support for pre-2.4 Python versions since such old Python versions are no longer officially supported nor are they tested anywhere.
• Updated documented project links to use HTTP instead of HTTPS protocol.
• Setup improvements.
  • Fixed setup to work with soft links in the current working folder path (contributed by ryanpetrello).
  • Project now installed as a zipped egg folder.
  • No longer attempts to work around Python 2.4.3 issues with urllib HTTPS downloads since now PyPI updated all of its links to HTTPS and the patch would need to become much more complex to deal with this, while making the setup much more difficult to understand and maintain.
    • On the other hand, this is now an extremely old Python version, so the change is not expected to have much impact. Anyone still using this version will just have to work around the issue manually, e.g. by downloading the necessary packages and running their setup procedures directly.
  • long_description field content wrapped to 72 characters, since PKG-INFO package distribution metadata file stores this text with an 8 space indentation.
• Improved internal project development documentation.
  • HACKING.txt updated, converted to .rst format & renamed to HACKING.rst.
  • Started internal project design, research & development notes documentation. Stored in a new notes/ subfolder, included in the project's source distribution, but not its builds or installations.
• Internal test suite improvements.
  • Added unit tests for transport related Request & Reply classes.
  • Improved HTTPTransport related unit tests.
  • Split up some web service operation invocation request construction tests into:
    • parameter definition tests
    • argument parsing tests
    • binding specific request construction tests
  • Many new tests added & existing ones extended.
  • Several redundant tests removed.
  • Added a basic development script for running the project's full test suite using multiple Python interpreter versions under Windows.
  • Better test support when running with disabled assertion optimizations enabled.
  • Cleaned up support for running test scripts directly as Python scripts.
    • May now be passed pytest command-line options.
    • Now return an exit code indicating the test result (0=success, !0=failure).

version 0.5 (2013-11-25)

• Based on revision 712 (1e48fd79a1fc323006826439e469ba7b3d2b5a68) from the original suds Python library development project's Subversion repository.
  • Last officially packaged & released suds Python library version - 0.4.1.
• Supported Python versions.
  • Intended to work with Python 2.4+.
  • Basic sources prepared for Python 2.x.
  • For using Python 3 the sources first processed by the Python py2to3 tool during the setup procedure.
  • Tested in the following environments:
    • Python 2.4.3/x86, on Windows 7/SP1/x64.
    • Python 2.4.4/x86, on Windows 7/SP1/x64.
    • Python 2.7.6/x64, on Windows 7/SP1/x64.
    • Python 3.2.5/x64, on Windows 7/SP1/x64.
    • Python 3.3.3/x86, on Windows 7/SP1/x64.
    • Python 3.3.3/x64, on Windows 7/SP1/x64.
• Updated the project's versioning scheme and detached it from the original suds project. The original project's stall seems to be long-term (likely permanent) and making our version information match the original one was getting to be too much of a hassle.
  • For example, with our original versioning scheme, latest pip versions recognize our package releases as 'development builds' and refuse to install them by default (supply the --pre command-line option to force the install anyway).
• Improved the suds date/time handling (contributed by MDuggan1, based on a patch attached to issue #353 on the original suds project issue tracker).
  • Replaces the timezone handling related fix made in the previous release.
  • More detailed testing.
  • Corrected subsecond to microsecond conversion, including rounding.
  • DateTime class no longer derived from Date & Time classes.
  • Recognizes more date/time strings valid 'by intuition'.
  • Rejects more invalid date/time strings.
    • Time zone specifiers containing hours and minutes but without a colon are rejected to avoid confusion, e.g. whether +121 should be interpreted as +12:01 or +01:21.
    • Time zone specifiers limited to under 24 hours. Without this Python's timezone UTC offset calculation would raise an exception on some operations, e.g. timezone aware datetime.datetime/time comparisons.
• Removed several project files related to the original developer's development environment.
• Removed several internal Mercurial version control system related files from the project's source distribution package.
• Better documented the project's development & testing environment.

version 0.4.1 jurko 5 (2013-11-11)

• Based on revision 712 (1e48fd79a1fc323006826439e469ba7b3d2b5a68) from the original suds Python library development project's Subversion repository.
  • Last officially packaged & released suds Python library version - 0.4.1.
• Supported Python versions.
  • Intended to work with Python 2.4+.
  • Basic sources prepared for Python 2.x.
  • For using Python 3 the sources first processed by the Python py2to3 tool during the setup procedure.
  • Tested in the following environments:
    • Python 2.4.3/x86, on Windows 7/SP1/x64.
    • Python 2.4.4/x86, on Windows 7/SP1/x64.
    • Python 2.7.3/x64, on Windows 7/SP1/x64.
    • Python 3.2.3/x64, on Windows 7/SP1/x64.
    • Python 3.3.2/x86, on Windows 7/SP1/x64.
    • Python 3.3.2/x64, on Windows 7/SP1/x64.
• Improved Python 3 support.
  • Cache files now used again.
    • Problems caused by cache files being stored in text mode, but attempting to write a bytes object in them. Too eager error handling was then causing all such cached file usage to fail silently.
  • WebFault containing non-ASCII data now gets constructed correctly.
  • Fixed issue with encoding of authentication in transport/http.py (contributed by Phillip Alday).
  • Unicode/byte string handling fixes.
• Fixed encoding long user credentials for basic HTTP authentication in transport/http.py (contributed by Jan-Wijbrand Kolman).
• Fixed an IndexError occurring when calling a web service operation with only a single input parameter.
• Fixed a log formatting error, originated in the original suds (contributed by Guy Rozendorn).
• Fixed local timezone detection code (contributed by Tim Savage).
• Setup updated.
  • Fixed a problem with running the project setup on non-Windows platforms.
    • version.py file loading no longer sensitive to the line-ending type used in that file.
    • Stopped using the distribute setup package since it has been merged back into the original setuptools project. Now using setuptools version 0.7.2 or later.
    • Automatically downloads & installs an appropriate setuptools package version if needed.
  • distutils obsoletes setup parameter usage removed when run using this Python versions earlier than 2.5 as that is the first version implementing support for this parameter.
• Removed different programming techniques & calls breaking compatibility with Python 2.4.
  • String format() method.
  • Ternary if operator.
• Project README file converted to .rst format (contributed by Phillip Alday).
• Corrected internal input/output binding usage. Output binding was being used in several places where the input one was expected.
• HTTP status code 200 XML replies containing a Fault element now consistently as a SOAP fault (plus a warning about the non-standard HTTP status code) both when reporting such faults using exceptions or by returning a (status, reason) tuple.
  • Before this was done only when reporting them using exceptions.
• Reply XML processing now checks the namespace used for Envelope & Body elements.
• SOAP fault processing now checks the namespaces used for all relevant tags.
• Plugins now get a chance to process received() & parsed() calls for both success & error replies.
• SOAP fault reports with invalid Fault structure no longer cause suds code to break with an 'invalid attribute' exception.
• SOAP fault reports with no <detail> tag (optional) no longer cause suds code to break with an 'invalid attribute' exception when run with the suds faults option set to False.
• Added correct handling for HTTP errors containing no input file information. Previously such cases caused suds to break with an 'invalid attribute' exception.
• SimClient injection keywords reorganized:
  • msg - request message.
  • reply - reply message ('msg' must not be set).
  • status - HTTP status code accompanying the 'reply' message.
  • description - description string accompanying the 'reply' message.
• Added unwrap option, allowing the user to disable suds library's automated simple document interface unwrapping (contributed by Juraj Ivančić).
• Fixed a problem with suds constructing parameter XML elements in its SOAP requests in incorrect namespaces in case they have been defined by XSD schema elements referencing XSD schema elements with a different target namespace.
• DocumentStore instance updated.
  • Separate DocumentStore instances now hold separate data with every instance holding all the hardcoded suds library XML document data.
  • DocumentStore now supports a dict-like update() method for adding new documents to it.
  • Client instances may now be given a specific DocumentStore instance using the 'documentStore' option. Not specifying the option uses a shared singleton instance. Specifying the option as None avoids using any document store whatsoever.
  • Suds tests no longer have to modify the global shared DocumentStore data in order to avoid loading its known data from external files and so may no longer affect each other by leaving behind data in that global shared DocumentStore.
  • Documents may now be fetched from a DocumentStore using a transport protocol other than suds. When using the suds protocol an exception is raised if the document could not be found in the store while in all other cases None is returned instead.
  • Documents in a DocumentStore are now accessed as bytes instead file-like stream objects.
  • Made more DocumentStore functions private.
• Corrected error message displayed in case of a transport error.
• Many unit tests updated and added.
• Unit tests may now be run using the setuptools setup.py test command.
  • Note that this method does not allow passing additional pytest testing framework command-line arguments. To specify any such parameters invoke the pytest framework directly, e.g. using python -m pytest in the project's root folder.
• Internal code cleanup.
  • Removed undocumented, unused and untested binding.replyfilter functionality.
  • Binding classes no longer have anything to do with method independent Fault element processing.
  • Removed SoapClient last_sent() and last_received() functions.
  • Fixed file closing in reader.py & cache.py modules - used files now closed explicitly in case of failed file operations instead of relying on the Python GC to close them 'some time later on'.
  • Fixed silently ignoring internal exceptions like KeyboardInterrupt in the cache.py module.
  • Removed unused Cache module getf() & putf() functions. getf() left only in FileCache and its derived classes.

version 0.4.1 jurko 4 (2012-04-17)

• Based on revision 712 (1e48fd79a1fc323006826439e469ba7b3d2b5a68) from the original suds Python library development project's Subversion repository.
  • Last officially packaged & released suds Python library version - 0.4.1.
• Supported Python versions.
  • Intended to work with Python 2.4+.
  • Basic sources prepared for Python 2.x.
  • For using Python 3 the sources first processed by the Python py2to3 tool during the setup procedure.

• Internal cleanup - renamed bounded to single_occurrence and unbounded to multi_occurrence.
• Original term unbounded meant that its object has more than one occurrence while its name inferred that 'it has no upper limit on its number of occurrences'.

version 0.4.1 jurko 3 (2011-12-26)

• Based on revision 711 (1be817c8a7672b001eb9e5cce8842ebd0bf424ee) from the original suds Python library development project's Subversion repository.
  • Last officially packaged & released suds Python library version - 0.4.1.

• Operation parameter specification string no longer includes a trailing comma.
• suds.xsd.xsbasic.Enumeration objects now list their value in their string representation.
• suds.sudsobject.Metadata __unicode__()/__str__()/__repr__() functions no longer raise an AttributeError when the object is not empty.
• Fixed a bug with suds.xsd.sxbasic.TypedContent.resolve() returning an incorrect type when called twice on the same node referencing a builtin type with the parameter nobuiltin=True.
• Added more test cases.

version 0.4.1 jurko 2 (2011-12-24)

• Based on revision 711 (1be817c8a7672b001eb9e5cce8842ebd0bf424ee) from the original suds Python library development project's Subversion repository.
  • Last officially packaged & released suds Python library version - 0.4.1.

  • Changed the way suds.client.Client to-string conversion outputs build info. This fixes a bug in the original 0.4.1 jurko 1 forked project release causing printing out a suds.client.Client object to raise an exception due to the code in question making some undocumented assumptions on how the build information string should be formatted.

version 0.4.1 jurko 1 (2011-12-24)

• Based on revision 711 (1be817c8a7672b001eb9e5cce8842ebd0bf424ee) from the original suds Python library development project's Subversion repository.
  • Last officially packaged & released suds Python library version - 0.4.1.
• Supported Python versions.
  • Intended to work with Python 2.4+.
  • Basic sources prepared for Python 2.x.
  • For using Python 3 the sources first processed by the Python py2to3 tool during the setup procedure.
  • Installation procedure requires the distribute Python package to be installed on the system.
  • Tested in the following environments:
    • Python 2.7.1/x86 on Windows XP/SP3/x86.
    • Python 3.2.2/x86 on Windows XP/SP3/x86.
• Added Python 3 support:
  • Based on patches integrated from a Mercurial patch queue maintained by Bernhard Leiner.
    • Last collected patch series commit: 96ffba978d5c74df28846b4273252cf1f94f7c78.
  • Original sources compatible with Python 2. Automated conversion to Python 3 sources during setup.
    • Automated conversion implemented by depending on the distribute setup package.
• Made suds work with operations taking choice parameters.
  • Based on a patch by michaelgruenewald & bennetb01 attached to ticket #342 on the original suds project issue tracker. Comments listed related to that ticket seem to indicate that there may be additional problems with this patch but so far we have not encountered any.
• Fixed the DateTimeTest.testOverflow test to work correctly in all timezones.
  • This test would fail if run directly when run on a computer with a positive timezone time adjustment while it would not fail when run together with all the other tests in this module since some other test would leave behind a nonpositive timezone adjustment setting. Now the test explicitly sets its own timezone time adjustment to a negative value.
  • Fixes a bug referenced in the original suds project issue tracker as ticket #422.
• Corrected accessing suds.xsd.sxbase.SchemaObject subitems by index.
  • Fixes a bug referenced in the original suds project issue tracker as ticket #420.
• Internal code & project data cleanup.
  • Extracted version information into a separate module.
  • Added missing release notes for the original suds Python library project.
  • Ported unit tests to the pytest testing framework.
  • Cleaned up project tests.
    • Separated standalone tests from those requiring an external web service.
    • Added additional unit tests.
    • Added development related documentation - HACKING.txt.
    • Setup procedure cleaned up a bit.
• Known defects.
  • Converting a suds.client.Client object to a string fails & raises an IndexError exception.

version 0.3.1 (2008-10-01)

• Quick follow up to the 0.3 release that made working multi-port service definitions harder then necessary. After consideration (and a good night sleep), it seemed obvious that a few changes would make this much easier:
  1. filter out the non-SOAP bindings - they were causing the real trouble;
  2. since most servers are happy with any of the SOAP bindings (SOAP 1.1 and 1.2), ambiguous references to methods when invoking then without the port qualification will work just fine in almost every case. So, why not just allow suds to select the port. Let us not make the user do it when it is not necessary. In most cases, users on 0.2.9 and earlier will not have to update their code when moving to 0.3.1 as they might have in 0.3.

version 0.3 (2008-09-30)

• Extends the support for multi-port services introduced in 0.2.9. This addition, provides for multiple services to define the same method and suds will handle it properly. See section 'SERVICES WITH MULTIPLE PORTS:'.
• Add support for multi-document document/literal SOAP binding style. See section 'MULTI-DOCUMENT Document/Literal:'.
• Add support for xs:group, xs:attributeGroup tags.
• Add Client.last_sent() and Client.last_received().

version 0.2.9 (2008-09-09)

• Support for multiple ports within a service.
• Attribute references <xs:attribute ref=""/>.
• Make XML special character encoder in sax package - pluggable.

version 0.2.8 (2008-08-28)

• Update document/literal binding to always send the document root referenced by the <part/>. After yet another review of the space and user input, seems like the referenced element is ALWAYS the document root.

• Add support for 'binding' schemaLocation``s to namespace-uri. This is for imports that do not specify a ``schemaLocation and still expect the schema to be downloaded. E.g. Axis references 'http://schemas.xmlsoap.org/soap/encoding/' without a schemaLocation. So, by doing this:

  >
  > from suds.xsd.sxbasic import Import
  > Import.bind('http://schemas.xmlsoap.org/soap/encoding/')
  >
  

  The schema is bound to a schemaLocation and it is downloaded.

• Basic unmarshaller does not need a schema. Should have been removed during refactoring but was missed.

• Update client to pass kwargs to send() and add location kwarg for overriding the service location in the WSDL.

• Update marshaller to NOT emit XML for object attributes that represent elements and/or attributes that are both optional and value=None.

  • Update factory (builder) to include all attributes.
  • Add optional() method to SchemaObject.

• Update WSDL to override namespace in operation if specified.

• Fix schema loading issue - build all schemas before processing imports.

• Update packaging in preparation of submission to fedora.

version 0.2.7 (2008-08-11)

• Add detection/support for document/literal - wrapped and unwrapped.
• Update document/literal {wrapped} to set document root (under <body/>) to be the wrapper element (w/ proper namespace).
• Add support for <sequence/>, <all/> and <choice/> having maxOccurs and have the. This causes the unmarshaller to set values for elements contained in an unbounded collection as a list.
• Update client.factory (builder) to omit children of <choice/> since the 'user' really needs to decide which children to include.
• Update flattening algorithm to prevent re-flattening of types from imported schemas.
• Adjustments to flattening/merging algorithms.

version 0.2.6 (2008-08-05)

• Fix ENUMs broken during xsd package overhaul.

• Fix type as defined in ticket #24.

• Fix duplicate param names in method signatures as reported in ticket #30.

• Suds licensed as LGPL.

• Remove logging setup in suds.__init__() as suggested by patch in ticket #31. Users will now need to configure the logger.

• Add support for Client.Factory.create() alt: syntax for fully qualifying the type to be built as: {namespace}name. E.g.:

  > client.factory.create('{http://blabla.com/ns}Person')
  

version 0.2.5 (2008-08-01)

• Overhauled the xsd package. This new (merging) approach is simpler and should be more reliable and maintainable. Also, should provide better performance since the merged schema performs lookups via dictionary lookup. This overhaul should fix current TypeNotFound and <xs:extension/> problems, I hope :-).
• Fixed dateTime printing bug.
• Added infinite recursion prevention in builder.Builder for XSD types that contain themselves.

version 0.2.4 (2008-07-28)

• Added support for WSDL imports: <wsdl:import/>.
• Added support for XSD<->python type conversions (thanks: Nathan Van Gheem) for:
  • xs:date
  • xs:time
  • xs:dateTime
• Fixed:
  • Bug: Schema <import/> with schemaLocation specified.
  • Bug: Namespaces specified in service description not valid until client/ proxy is printed.

version 0.2.3 (2008-07-23)

• Optimizations.

version 0.2.2 (2008-07-08)

• Update exceptions to be more /standard/ python by using Exception.__init__() to set Exception.message as suggested by ticket #14; update bindings to raise WebFault passing (p).

• Add capability in bindings to handle multiple root nodes in the returned values; returned as a composite object unlike when lists are returned.

• Fix soapAction to be enclosed by quotes.

• Add support for <xs:all/>.

• Fix unbounded() method in SchemaObject.

• Refactored schema into new xsd package. Files just getting too big. Added execute() to Query and retrofitted suds to execute() query instead of using Schema.find() directly. Also, moved hokey start() methods from schema, as well as, query incrementation.

• Add inject keyword used to inject outbound SOAP messages and/or inbound reply messages.

• Refactored SoapClient and

  1. rename send() to invoke()
  2. split message sending from invoke() and place in send()

• Add TestClient which allows for invocation kwargs to have inject={'msg=, and reply='} for message and reply injection.

• Add Namespace class to sax for better management of namespace behavior; retrofix suds to import and use Namespace.

• Change the default namespace used to resolve referenced types (having attributes @base="", @type="") so that when no prefix is specified: uses XML (node) namespace instead of the targetNamespace.

• Apply fix as defined by [email protected] in ticket #13.

• Update service definition to print to display service methods as my_method(xs:int arg0, Person arg1) instead of my_method(arg0{xs:int}, arg1{Person}) which is more like traditional method signatures.

• Add XSD/python type conversion to unmarshaller (XBoolean only); refactor unmarshaller to use Content class which makes APIs cleaner, adds symmetry between marshaller(s) and unmarshaller(s), provides good mechanism for schema-property based type conversions.

• Refactored marshaller with Appenders; add nobuiltin flag to resolve() to support fix for returned_type() and returned_collection() in bindings.

• Add support for (202, 204) HTTP codes.

• Add XBoolean and mappings; add findattr() to TreeResolver in preparation for type conversions.

• Updated schema and schema property loading (deep recursion stopped); Changed Imported schemas so then no longer copy imported schemas, rather the import proxies find requests; Add ServiceDefinition class which provides better service inspection; also provides namespace mapping and show types; schema property API simplified; support for xs:any and xs:anyType added; Some schema lookup problems fixed; Binding classes refactored slightly; A lot of debug logging added (might have to comment some out for performance - some of the args are expensive).

• Add sudsobject.Property; a property is a special Object that contains a value attribute and is returned by the Builder (factory) for schema-types without children such as: <element/> and <simpleType/>; Builder, Marshaller and Resolver updated to handle Properties; Resolver and Schema also updated to handle attribute lookups (this was missing).

• Add groundwork for user defined SOAP headers.

• Fix elementFormDefault per ticket #7

• Remove unused kwargs from bindings; cache bindings in WSDL; retrofit legacy ServiceProxy to delegate to {new} Client API; remove keyword nil_supported in favor of natural handling by nillable attribute on <element/> within schemas.

• Add support for <element/> attribute flags (nillable and form).

• Add the Proxy (2nd generation API) class.

• Add accessor/conversion functions so that users do not need to access __x__ attributes. Also add todict() and get_items() for easy conversion to dictionary and iteration.

• Search top-level elements for @ref before looking deeper.

• Add derived() to SchemaObject. This is needed to ensure that all derived types (WSDL classes) are qualified by xsi:type without specifying the xsi:type for all custom types as did in earlier suds releases. Update the literal marshaller to only add the xsi:type when the type needs to be specified.

• Change ns promotion in sax to prevent ns promoted to parent when parent has the prefix.

• Changed binding returned_type() to return the (unresolved) Element.

• In order to support the new features and fix reported bugs, I'm in the process of refactoring and hopefully evolving the components in suds that provide the input/output translations:

  • Builder (translates: XSD objects => python objects)
  • Marshaller (translates: python objects => XML/SOAP)
  • Unmarshaller (translates: XML/SOAP => python objects)

  This evolution will provide better symmetry between these components as follows:

  The Builder and Unmarshaller will produce python (subclass of sudsobject.Object) objects with:

  • __metadata__.__type__ = XSD type (SchemaObject)
  • subclass name (__class__.__name__) = schema-type name

  and

  The Marshaller, while consuming python objects produced by the Builder or Unmarshaller, will leverage this standard information to produce the appropriate output (XML/SOAP).

  The 0.2.1 code behaves mostly like this but ... not quite. Also, the implementations have some redundancy.

  While doing this, it made sense to factor out the common schema-type "lookup" functionality used by the Builder, Marshaller and Unmarshaller classes into a hierarchy of Resolver classes. This reduces the complexity and redundancy of the Builder, Marshaller and Unmarshaller classes and allows for better modularity. Once this refactoring was complete, the difference between the literal/encoded Marshallers became very small. Given that the amount of code in the bindings.literal and bindings.encoded packages was small (and getting smaller) and in the interest of keeping the suds code base compact, I moved all of the marshalling classes to the bindings.marshaller module. All of the bindings.XX sub-packages will be removed.

  The net effect:

  All of the suds major components:

  • client (old: service proxy)
  • WSDL
    • schema (xsd package)
    • resolvers
  • output (marshalling)
  • builder
  • input (unmarshalling)

  Now have better:

  • modularity
  • symmetry with regard to Object metadata.
  • code re-use (< 1% code duplication --- I hope)
  • looser coupling

  and better provide for the following features/bug-fix:

  • Proper level of XML element qualification based on <schema elementFormDefault=""/> attribute. This will ensure that when elementFormDefault="qualified", suds will include the proper namespace on root elements for both literal and encoded bindings. In order for this to work properly, the literal marshaller (like the encoded marshaller) needed to be schema-type aware. Had I added the same schema-type lookup as the encoded marshaller instead of the refactoring described above, the two classes would have been almost a complete duplicate of each other :-(

• The builder and unmarshaller used the schema.Schema.find() to resolve schema-types. They constructed a path as person.name.first to resolve types in proper context. Since Schema.find() was stateless, it resolved the intermediate path elements on every call. The new resolver classes are stateful and resolve child types much more efficiently.

• Prevent name collisions in sudsobject.Object like the items() method. I've moved all methods (including class methods) to a Factory class that is included in the Object class as a class attr (__factory__). Now that all attributes have python built-in naming, we should not have any more name collisions. This of course assumes that no WSDL/schema entity names will have a name with the python built-in naming convention but I have to draw the line somewhere. :-)

version 0.2.1 (2008-05-08)

• Update the schema.py SchemaProperty loading sequence so that the schema is loaded in 3 steps:

  1. Build the raw tree.
  2. Resolve dependencies such as @ref and @base.
  3. Promote grandchildren as needed to flatten (denormalize) the tree.

  The WSDL was also changed to only load the schema once and store it. The schema collection was changed to load schemas in 2 steps:

  1. Create all raw schema objects.
  2. Load schemas.

  This ensures that local imported schemas can be found when referenced out of order. The sax.py Element interface changed: attribute() replaced by get() and set(). Also, __getitem__() and __setitem__() can be used to access attribute values. Epydocs updated for sax.py. And ... last <element ref=/> now supported properly.

• Fix logging by: NOT setting to info in suds.__init__.logger(); set handler on root logger only; moved logger (log) from classes to modules and use __name__ for logger name. NOTE: This means that to enable SOAP message logging one should use:

  >
  > logger('suds.serviceproxy').setLevel(logging.DEBUG)
  >
  

  instead of:

  >
  > logger('serviceproxy').setLevel(logging.DEBUG)
  >
  

• Add support for XSD schema <attribute/> nodes which primarily affects objects returned by the Builder.

• Update serviceproxy.py:set_proxies() to log DEBUG instead of INFO.

• Enhance schema __str__() to show both the raw XML and the model (mostly for debugging).

version 0.2 (2008-04-28)

• Contains the first cut at the rpc/encoded SOAP style.

• Replaced Property class with suds.sudsobject.Object. The Property class was developed a long time ago with a slightly different purpose. The suds Object is a simpler (more straight forward) approach that requires less code and works better in the debugger.

• The Binding (and the encoding) is selected on a per-method basis which is more consistent with the WSDL. In <= 0.1.7, the binding was selected when the ServiceProxy was constructed and used for all service methods. The binding was stored as self.binding. Since the WSDL provides for a separate binding style and encoding for each operation, suds needed to be change to work the same way.

• The nil_supported and faults flag(s) passed into the service proxy using **kwargs. In addition to these flags, a http_proxy flag has been added and is passed to the urllib2.Request object. The following args are supported:

  • faults = Raise faults raised by server (default:True), else return tuple from service method invocation as (HTTP code, object).
  • nil_supported = The bindings will set the xsi:nil="true" on nodes that have a value=None when this flag is True (default:True). Otherwise, an empty node <x/> is sent.
  • proxy = An HTTP proxy to be specified on requests (default:{}). The proxy is defined as {protocol:proxy,}.

• HTTP proxy supported (see above).

• ServiceProxy refactored to delegate to a SoapClient. Since the service proxy exposes web services via getattr(), any attribute (including methods) provided by the ServiceProxy class hides WS operations defined by the WSDL. So, by moving everything to the SoapClient, WSDL operations are no longer hidden without having to use hokey names for attributes and methods in the service proxy. Instead, the service proxy has __client__ and __factory__ attributes (which really should be at low risk for name collision). For now the get_instance() and get_enum() methods have not been moved to preserve backward compatibility. Although, the preferred API change would to replace:

  > service = ServiceProxy('myurl')
  > person = service.get_instance('person')
  

  with something like:

  > service = ServiceProxy('myurl')
  > person = service.__factory__.get_instance('person')
  

  After a few releases giving time for users to switch the new API, the get_instance() and get_enum() methods may be removed with a notice in big letters.

• Fixed problem where a WSDL does not define a <schema/> section and suds can not resolve the prefixes for the http://www.w3.org/2001/XMLSchema namespace to detect builtin types such as xs:string.

version 0.1.7 (2008-04-08)

• Added Binding.nil_supported to control how property values (out) = None and empty tag (in) are processed.
  • service.binding.nil_supported = True -- means that property values = None are marshalled (out) as <x xsi:nil=true/> and <x/> is unmarshalled as '' and <x xsi:nil/> is unmarshalled as None.
  • service.binding.nil_supported = False -- means that property values = None are marshalled (out) as <x/> and <x xsi:nil=true/> is unmarshalled as None. The xsi:nil is really ignored.
  • THE DEFAULT IS True.
• Sax handler updated to handle multiple character() callbacks when the sax parser "chunks" the text. When the node.text is None, the node.text is set to the characters. Else, the characters are appended. Thanks - '[email protected]'.
• Replaced special text attribute with __text__ to allow for natural elements named "text".
• Add unicode support by:
  • Add __unicode__() to all classes with __str__().
  • Replace all str() calls with unicode().
  • __str__() returns UTF-8 encoded result of __unicode__().
• XML output encoded as UTF-8 which matches the HTTP header and supports unicode.
• SchemaCollection changed to provide the builtin() and custom() methods. To support this, findPrefixes() was added to the Element in sax.py. This is a better approach anyway since the WSDL and schemas may have many prefixes to 'http://www.w3.org/2001/XMLSchema'. Tested using both doc/lit and rpc/lit bindings.
• Refactored bindings packages from document & rpc to literal & encoded.
• Contains the completion of full namespace support as follows:
  • Namespace prefixes are no longer stripped from attribute values that reference types defined in the WSDL.
  • Schema's imported using <import/> should properly handle namespace and prefix mapping and re-mapping as needed.
  • All types are resolved, using fully qualified (w/ namespaces) lookups.
  • Schema.get_type() supports paths with and without ns prefixes. When no prefix is specified the type is matched using the schema's target namespace.
• Property maintains attribute names (keys) in the order added. This also means that get_item() and get_names() return ordered values. Although, I suspect ordering really needs to be done in the marshaller using the order specified in the WSDL/schema.
• Major refactoring of the schema.py. The primary goals is preparation for type lookups that are fully qualified by namespace. Once completed, the prefixes on attribute values will no longer be stripped (purged). Change summary:
  1. SchemaProperty overlay classes created at __init__() instead of on-demand.
  2. schema imports performed by new Import class instead of by Schema.
  3. Schema loads top level properties using a factory.
  4. All SchemaProperty /children/ lists are sorted by __cmp__() in SchemaProperty derived classes. This ensures that types with the same name are resolved in the following order (Import, Complex, Simple, Element).
  5. All /children/ SchemaProperty lists are constructed at __init__() instead of on-demand.
  6. The SchemaGroup created and WSDL class updated. This works better then having the WSDL aggregate the <schema/> nodes which severs linkage to the WSDL parent element that have namespace prefix mapping.
  7. <import/> element handles properly in that both namespace remapping and prefix re-mapping of the imported schema's targetNamespace and associated prefix mapping - is performed. E.g. SCHEMA-A has prefix tns mapped as xmlns:tns=http://nsA and has targetNamespace='http://nsA'. SCHEMA-B is importing schema A and has prefix abc mapped as xmlns:abc='http://nsABC'. SCHEMA-B imports A as <import namespace=http://nsB xxx schemaLocation=http://nsA/schema-a.xsd>. So, since SCHEMA-B will be referencing elements of SCHEMA-A with prefix abc such as abc:something, SCHEMA-A's targetNamespace must be updated as http://nsABC and all elements with type=tns:something must be updated to be type=abc:something so they can be resolved.
• Fixes unmarshalling problem where nodes are added to property as (text, value). This was introduced when the bindings were refactored.
• Fixed various Property print problems.

Notes:

Thanks to Jesper Noehr of Coniuro for the majority of the rpc/literal binding and for lots of collaboration on #suds.

version 0.1.6 (2008-03-06)

• Provides proper handling of WSDLs that contain schema sections containing XSD schema imports: <import namespace="" schemaLocation=""?>. The referenced schemas are imported when a schemaLocation is specified.
• Raises exceptions for HTTP status codes not already handled.

version 0.1.5 (2008-02-21)

• Provides better logging in the modules get logger by hierarchal names.

version 0.1.4 (2007-12-21)

• Provides for service method parameters to be None.
• Add proper handling of method params that are lists of property objects.

version 0.1.3 (2007-12-19)

• Fixes problem where nodes marked as a collection (maxOccurs > 1) not creating property objects with value=[] when mapped-in with < 2 values by the DocumentReader. Caused by missing the bindings.Document.ReplyHint.stripns()` (which uses ``DocumentReader.stripns()) conversion to DocumentReader.stripn() now returning a tuple (ns, tag) as of 0.1.2.

version 0.1.2 (2007-12-18)

• This release contains an update to property adds:
  • Metadata support.
