:mod:`xml.parsers.expat` --- Fast XML parsing using Expat
=========================================================
.. module:: xml.parsers.expat
:synopsis: An interface to the Expat non-validating XML parser.
.. moduleauthor:: Paul Prescod <paul@prescod.net>
.. Markup notes:
Many of the attributes of the XMLParser objects are callbacks. Since
signature information must be presented, these are described using the method
directive. Since they are attributes which are set by client code, in-text
references to these attributes should be marked using the :member: role.

.. warning::
The :mod:`pyexpat` module is not secure against maliciously
constructed data. If you need to parse untrusted or unauthenticated data see
:ref:`xml-vulnerabilities`.

.. index:: single: Expat
The :mod:`xml.parsers.expat` module is a Python interface to the Expat
non-validating XML parser. The module provides a single extension type,
:class:`xmlparser`, that represents the current state of an XML parser. After
an :class:`xmlparser` object has been created, various attributes of the object
can be set to handler functions. When an XML document is then fed to the
parser, the handler functions are called for the character data and markup in
the XML document.
.. index:: module: pyexpat
This module uses the :mod:`pyexpat` module to provide access to the Expat
parser. Direct use of the :mod:`pyexpat` module is deprecated.
This module provides one exception and one type object:
.. exception:: ExpatError
The exception raised when Expat reports an error. See section
:ref:`expaterror-objects` for more information on interpreting Expat errors.
.. exception:: error
Alias for :exc:`ExpatError`.
.. data:: XMLParserType
The type of the return values from the :func:`ParserCreate` function.
The :mod:`xml.parsers.expat` module contains two functions:
.. function:: ErrorString(errno)
Returns an explanatory string for a given error number *errno*.
.. function:: ParserCreate(encoding=None, namespace_separator=None)
2007-08-15 11:28:22 -03:00
Creates and returns a new :class:`xmlparser` object. *encoding*, if specified,
must be a string naming the encoding used by the XML data. Expat doesn't
support as many encodings as Python does, and its repertoire of encodings can't
be extended; it supports UTF-8, UTF-16, ISO-8859-1 (Latin1), and ASCII. If

*encoding* [1]_ is given it will override the implicit or explicit encoding of the
2007-08-15 11:28:22 -03:00
document.
Expat can optionally do XML namespace processing for you, enabled by providing a
value for *namespace_separator*. The value must be a one-character string; a
:exc:`ValueError` will be raised if the string has an illegal length (``None``
is considered the same as omission). When namespace processing is enabled,
element type names and attribute names that belong to a namespace will be
expanded. The element name passed to the element handlers
:attr:`StartElementHandler` and :attr:`EndElementHandler` will be the
concatenation of the namespace URI, the namespace separator character, and the
local part of the name. If the namespace separator is a zero byte (``chr(0)``)
then the namespace URI and the local part will be concatenated without any
separator.
For example, if *namespace_separator* is set to a space character (``' '``) and
the following document is parsed::
<?xml version="1.0"?>
<root xmlns = "http://default-namespace.org/"
xmlns:py = "http://www.python.org/ns/">
<py:elem1 />
<elem2 xmlns="" />
</root>
:attr:`StartElementHandler` will receive the following strings for each
element::
http://default-namespace.org/ root
http://www.python.org/ns/ elem1
elem2

.. _xmlparser-objects:
XMLParser Objects
-----------------
:class:`xmlparser` objects have the following methods:
.. method:: xmlparser.Parse(data[, isfinal])
Parses the contents of the string *data*, calling the appropriate handler
functions to process the parsed data. *isfinal* must be true on the final call
to this method. *data* can be the empty string at any time.
.. method:: xmlparser.ParseFile(file)
Parse XML data reading from the object *file*. *file* only needs to provide
the ``read(nbytes)`` method, returning the empty string when there's no more
data.
.. method:: xmlparser.SetBase(base)
Sets the base to be used for resolving relative URIs in system identifiers in
declarations. Resolving relative identifiers is left to the application: this
value will be passed through as the *base* argument to the
:func:`ExternalEntityRefHandler`, :func:`NotationDeclHandler`, and
:func:`UnparsedEntityDeclHandler` functions.
.. method:: xmlparser.GetBase()
Returns a string containing the base set by a previous call to :meth:`SetBase`,
or ``None`` if :meth:`SetBase` hasn't been called.
.. method:: xmlparser.GetInputContext()
Returns the input data that generated the current event as a string. The data is
in the encoding of the entity which contains the text. When called while an
event handler is not active, the return value is ``None``.
.. method:: xmlparser.ExternalEntityParserCreate(context[, encoding])
Create a "child" parser which can be used to parse an external parsed entity
referred to by content parsed by the parent parser. The *context* parameter
should be the string passed to the :meth:`ExternalEntityRefHandler` handler
function, described below. The child parser is created with the
:attr:`ordered_attributes` and :attr:`specified_attributes` set to the values of
this parser.
.. method:: xmlparser.SetParamEntityParsing(flag)
Control parsing of parameter entities (including the external DTD subset).
Possible *flag* values are :const:`XML_PARAM_ENTITY_PARSING_NEVER`,
:const:`XML_PARAM_ENTITY_PARSING_UNLESS_STANDALONE` and
:const:`XML_PARAM_ENTITY_PARSING_ALWAYS`. Return true if setting the flag
was successful.
2007-08-15 11:28:22 -03:00
.. method:: xmlparser.UseForeignDTD([flag])
Calling this with a true value for *flag* (the default) will cause Expat to call
the :attr:`ExternalEntityRefHandler` with :const:`None` for all arguments to
allow an alternate DTD to be loaded. If the document does not contain a
document type declaration, the :attr:`ExternalEntityRefHandler` will still be
called, but the :attr:`StartDoctypeDeclHandler` and
:attr:`EndDoctypeDeclHandler` will not be called.
Passing a false value for *flag* will cancel a previous call that passed a true
value, but otherwise has no effect.
This method can only be called before the :meth:`Parse` or :meth:`ParseFile`
methods are called; calling it after either of those have been called causes
:exc:`ExpatError` to be raised with the :attr:`code` attribute set to
``errors.codes[errors.XML_ERROR_CANT_CHANGE_FEATURE_ONCE_PARSING]``.
2007-08-15 11:28:22 -03:00
:class:`xmlparser` objects have the following attributes:
.. attribute:: xmlparser.buffer_size
2009-01-03 17:18:54 -04:00
The size of the buffer used when :attr:`buffer_text` is true.
A new buffer size can be set by assigning a new integer value
to this attribute.

When the size is changed, the buffer will be flushed.
2007-08-15 11:28:22 -03:00
.. attribute:: xmlparser.buffer_text
Setting this to true causes the :class:`xmlparser` object to buffer textual
content returned by Expat to avoid multiple calls to the
:meth:`CharacterDataHandler` callback whenever possible. This can improve
performance substantially since Expat normally breaks character data into chunks
at every line ending. This attribute is false by default, and may be changed at
any time.
.. attribute:: xmlparser.buffer_used
If :attr:`buffer_text` is enabled, the number of bytes stored in the buffer.
These bytes represent UTF-8 encoded text. This attribute has no meaningful
interpretation when :attr:`buffer_text` is false.
.. attribute:: xmlparser.ordered_attributes
Setting this attribute to a non-zero integer causes the attributes to be
reported as a list rather than a dictionary. The attributes are presented in
the order found in the document text. For each attribute, two list entries are
presented: the attribute name and the attribute value. (Older versions of this
module also used this format.) By default, this attribute is false; it may be
changed at any time.
.. attribute:: xmlparser.specified_attributes
If set to a non-zero integer, the parser will report only those attributes which
were specified in the document instance and not those which were derived from
attribute declarations. Applications which set this need to be especially
careful to use what additional information is available from the declarations as
needed to comply with the standards for the behavior of XML processors. By
default, this attribute is false; it may be changed at any time.
The following attributes contain values relating to the most recent error
encountered by an :class:`xmlparser` object, and will only have correct values
once a call to :meth:`Parse` or :meth:`ParseFile` has raised a
:exc:`xml.parsers.expat.ExpatError` exception.
.. attribute:: xmlparser.ErrorByteIndex
Byte index at which an error occurred.
.. attribute:: xmlparser.ErrorCode
Numeric code specifying the problem. This value can be passed to the
:func:`ErrorString` function, or compared to one of the constants defined in the
``errors`` object.
.. attribute:: xmlparser.ErrorColumnNumber
Column number at which an error occurred.
.. attribute:: xmlparser.ErrorLineNumber
Line number at which an error occurred.
The following attributes contain values relating to the current parse location
in an :class:`xmlparser` object. During a callback reporting a parse event they
indicate the location of the first of the sequence of characters that generated
the event. When called outside of a callback, the position indicated will be
just past the last parse event (regardless of whether there was an associated
callback).
.. attribute:: xmlparser.CurrentByteIndex
Current byte index in the parser input.
.. attribute:: xmlparser.CurrentColumnNumber
Current column number in the parser input.
.. attribute:: xmlparser.CurrentLineNumber
Current line number in the parser input.
Here is the list of handlers that can be set. To set a handler on an
:class:`xmlparser` object *o*, use ``o.handlername = func``. *handlername* must
be taken from the following list, and *func* must be a callable object accepting
the correct number of arguments. The arguments are all strings, unless
otherwise stated.
.. method:: xmlparser.XmlDeclHandler(version, encoding, standalone)
Called when the XML declaration is parsed. The XML declaration is the
(optional) declaration of the applicable version of the XML recommendation, the
encoding of the document text, and an optional "standalone" declaration.
*version* and *encoding* will be strings, and *standalone* will be ``1`` if the
document is declared standalone, ``0`` if it is declared not to be standalone,
or ``-1`` if the standalone clause was omitted. This is only available with
Expat version 1.95.0 or newer.
.. method:: xmlparser.StartDoctypeDeclHandler(doctypeName, systemId, publicId, has_internal_subset)
Called when Expat begins parsing the document type declaration (``<!DOCTYPE
...``). The *doctypeName* is provided exactly as presented. The *systemId* and
*publicId* parameters give the system and public identifiers if specified, or
``None`` if omitted. *has_internal_subset* will be true if the document
contains and internal document declaration subset. This requires Expat version
1.2 or newer.
.. method:: xmlparser.EndDoctypeDeclHandler()
Called when Expat is done parsing the document type declaration. This requires
Expat version 1.2 or newer.
.. method:: xmlparser.ElementDeclHandler(name, model)
Called once for each element type declaration. *name* is the name of the
element type, and *model* is a representation of the content model.
.. method:: xmlparser.AttlistDeclHandler(elname, attname, type, default, required)
Called for each declared attribute for an element type. If an attribute list
declaration declares three attributes, this handler is called three times, once
for each attribute. *elname* is the name of the element to which the
declaration applies and *attname* is the name of the attribute declared. The
attribute type is a string passed as *type*; the possible values are
``'CDATA'``, ``'ID'``, ``'IDREF'``, ... *default* gives the default value for
the attribute used when the attribute is not specified by the document instance,
or ``None`` if there is no default value (``#IMPLIED`` values). If the
attribute is required to be given in the document instance, *required* will be
true. This requires Expat version 1.95.0 or newer.
.. method:: xmlparser.StartElementHandler(name, attributes)
Called for the start of every element. *name* is a string containing the
element name, and *attributes* is the element attributes. If
:attr:`ordered_attributes` is true, this is a list (see
:attr:`ordered_attributes` for a full description). Otherwise it's a
dictionary mapping names to values.
2007-08-15 11:28:22 -03:00
.. method:: xmlparser.EndElementHandler(name)
Called for the end of every element.
.. method:: xmlparser.ProcessingInstructionHandler(target, data)
Called for every processing instruction.
.. method:: xmlparser.CharacterDataHandler(data)
Called for character data. This will be called for normal character data, CDATA
marked content, and ignorable whitespace. Applications which must distinguish
these cases can use the :attr:`StartCdataSectionHandler`,
:attr:`EndCdataSectionHandler`, and :attr:`ElementDeclHandler` callbacks to
collect the required information.
.. method:: xmlparser.UnparsedEntityDeclHandler(entityName, base, systemId, publicId, notationName)
Called for unparsed (NDATA) entity declarations. This is only present for
version 1.2 of the Expat library; for more recent versions, use
:attr:`EntityDeclHandler` instead. (The underlying function in the Expat
library has been declared obsolete.)
.. method:: xmlparser.EntityDeclHandler(entityName, is_parameter_entity, value, base, systemId, publicId, notationName)
Called for all entity declarations. For parameter and internal entities,
*value* will be a string giving the declared contents of the entity; this will
be ``None`` for external entities. The *notationName* parameter will be
``None`` for parsed entities, and the name of the notation for unparsed
entities. *is_parameter_entity* will be true if the entity is a parameter entity
or false for general entities (most applications only need to be concerned with
general entities). This is only available starting with version 1.95.0 of the
Expat library.
.. method:: xmlparser.NotationDeclHandler(notationName, base, systemId, publicId)
Called for notation declarations. *notationName*, *base*, and *systemId*, and
*publicId* are strings if given. If the public identifier is omitted,
*publicId* will be ``None``.
.. method:: xmlparser.StartNamespaceDeclHandler(prefix, uri)
Called when an element contains a namespace declaration. Namespace declarations
are processed before the :attr:`StartElementHandler` is called for the element
on which declarations are placed.
.. method:: xmlparser.EndNamespaceDeclHandler(prefix)
Called when the closing tag is reached for an element that contained a
namespace declaration. This is called once for each namespace declaration on
the element in the reverse of the order for which the
:attr:`StartNamespaceDeclHandler` was called to indicate the start of each
namespace declaration's scope. Calls to this handler are made after the
corresponding :attr:`EndElementHandler` for the end of the element.
.. method:: xmlparser.CommentHandler(data)
Called for comments. *data* is the text of the comment, excluding the leading
2012-09-20 03:47:03 -03:00
``'<!-``\ ``-'`` and trailing ``'-``\ ``->'``.
2007-08-15 11:28:22 -03:00
.. method:: xmlparser.StartCdataSectionHandler()
Called at the start of a CDATA section. This and :attr:`EndCdataSectionHandler`
are needed to be able to identify the syntactical start and end for CDATA
sections.
.. method:: xmlparser.EndCdataSectionHandler()
Called at the end of a CDATA section.
.. method:: xmlparser.DefaultHandler(data)
Called for any characters in the XML document for which no applicable handler
has been specified. This means characters that are part of a construct which
could be reported, but for which no handler has been supplied.
.. method:: xmlparser.DefaultHandlerExpand(data)
This is the same as the :func:`DefaultHandler`, but doesn't inhibit expansion
of internal entities. The entity reference will not be passed to the default
handler.
.. method:: xmlparser.NotStandaloneHandler()
Called if the XML document hasn't been declared as being a standalone document.
This happens when there is an external subset or a reference to a parameter
entity, but the XML declaration does not set standalone to ``yes`` in an XML
declaration. If this handler returns ``0``, then the parser will raise an
2007-08-15 11:28:22 -03:00
:const:`XML_ERROR_NOT_STANDALONE` error. If this handler is not set, no
exception is raised by the parser for this condition.
.. method:: xmlparser.ExternalEntityRefHandler(context, base, systemId, publicId)
Called for references to external entities. *base* is the current base, as set
by a previous call to :meth:`SetBase`. The public and system identifiers,
*systemId* and *publicId*, are strings if given; if the public identifier is not
given, *publicId* will be ``None``. The *context* value is opaque and should
only be used as described below.
For external entities to be parsed, this handler must be implemented. It is
responsible for creating the sub-parser using
``ExternalEntityParserCreate(context)``, initializing it with the appropriate
callbacks, and parsing the entity. This handler should return an integer; if it
returns ``0``, the parser will raise an
2007-08-15 11:28:22 -03:00
:const:`XML_ERROR_EXTERNAL_ENTITY_HANDLING` error, otherwise parsing will
continue.
If this handler is not provided, external entities are reported by the
:attr:`DefaultHandler` callback, if provided.

ExpatError Exceptions
---------------------
.. sectionauthor:: Fred L. Drake, Jr. <fdrake@acm.org>
:exc:`ExpatError` exceptions have a number of interesting attributes:
.. attribute:: ExpatError.code
Expat's internal error number for the specific error. The
:data:`errors.messages <xml.parsers.expat.errors.messages>` dictionary maps
these error numbers to Expat's error messages. For example::
from xml.parsers.expat import ParserCreate, ExpatError, errors
p = ParserCreate()
try:
p.Parse(some_xml_document)
except ExpatError as err:
print("Error:", errors.messages[err.code])
The :mod:`~xml.parsers.expat.errors` module also provides error message
constants and a dictionary :data:`~xml.parsers.expat.errors.codes` mapping
these messages back to the error codes, see below.
2007-08-15 11:28:22 -03:00
.. attribute:: ExpatError.lineno
Line number on which the error was detected. The first line is numbered ``1``.
.. attribute:: ExpatError.offset
Character offset into the line where the error occurred. The first column is
numbered ``0``.
.. _expat-example:
Example
-------
The following program defines three handlers that just print out their
arguments. ::
import xml.parsers.expat
# 3 handler functions
def start_element(name, attrs):
print('Start element:', name, attrs)
2007-08-15 11:28:22 -03:00
def end_element(name):
print('End element:', name)
2007-08-15 11:28:22 -03:00
def char_data(data):
print('Character data:', repr(data))
2007-08-15 11:28:22 -03:00
p = xml.parsers.expat.ParserCreate()
p.StartElementHandler = start_element
p.EndElementHandler = end_element
p.CharacterDataHandler = char_data
p.Parse("""<?xml version="1.0"?>
<parent id="top"><child1 name="paul">Text goes here</child1>
<child2 name="fred">More text</child2>
</parent>""", 1)
The output from this program is::
Start element: parent {'id': 'top'}
Start element: child1 {'name': 'paul'}
Character data: 'Text goes here'
End element: child1
Character data: '\n'
Start element: child2 {'name': 'fred'}
Character data: 'More text'
End element: child2
Character data: '\n'
End element: parent
.. _expat-content-models:
Content Model Descriptions
--------------------------
.. module:: xml.parsers.expat.model
2007-08-15 11:28:22 -03:00
.. sectionauthor:: Fred L. Drake, Jr. <fdrake@acm.org>
2007-08-15 11:28:22 -03:00
Content modules are described using nested tuples. Each tuple contains four
values: the type, the quantifier, the name, and a tuple of children. Children
are simply additional content module descriptions.
The values of the first two fields are constants defined in the
:mod:`xml.parsers.expat.model` module. These constants can be collected in two
2007-08-15 11:28:22 -03:00
groups: the model type group and the quantifier group.
The constants in the model type group are:
.. data:: XML_CTYPE_ANY
:noindex:
The element named by the model name was declared to have a content model of
``ANY``.
.. data:: XML_CTYPE_CHOICE
:noindex:
The named element allows a choice from a number of options; this is used for
content models such as ``(A | B | C)``.
.. data:: XML_CTYPE_EMPTY
:noindex:
Elements which are declared to be ``EMPTY`` have this model type.
.. data:: XML_CTYPE_MIXED
:noindex:
.. data:: XML_CTYPE_NAME
:noindex:
.. data:: XML_CTYPE_SEQ
:noindex:
Models which represent a series of models which follow one after the other are
indicated with this model type. This is used for models such as ``(A, B, C)``.
The constants in the quantifier group are:
.. data:: XML_CQUANT_NONE
:noindex:
No modifier is given, so it can appear exactly once, as for ``A``.
.. data:: XML_CQUANT_OPT
:noindex:
The model is optional: it can appear once or not at all, as for ``A?``.
.. data:: XML_CQUANT_PLUS
:noindex:
The model must occur one or more times (like ``A+``).
.. data:: XML_CQUANT_REP
:noindex:
The model must occur zero or more times, as for ``A*``.
.. _expat-errors:
Expat error constants
---------------------
.. module:: xml.parsers.expat.errors
The following constants are provided in the :mod:`xml.parsers.expat.errors`
module. These constants are useful in interpreting some of the attributes of
the :exc:`ExpatError` exception objects raised when an error has occurred.
Since for backwards compatibility reasons, the constants' value is the error
*message* and not the numeric error *code*, you do this by comparing its
:attr:`code` attribute with
:samp:`errors.codes[errors.XML_ERROR_{CONSTANT_NAME}]`.
The ``errors`` module has the following attributes:
.. data:: codes
A dictionary mapping numeric error codes to their string descriptions.
.. versionadded:: 3.2
.. data:: messages
A dictionary mapping string descriptions to their error codes.
2007-08-15 11:28:22 -03:00
.. versionadded:: 3.2
2007-08-15 11:28:22 -03:00
.. data:: XML_ERROR_ASYNC_ENTITY
.. data:: XML_ERROR_ATTRIBUTE_EXTERNAL_ENTITY_REF
An entity reference in an attribute value referred to an external entity instead
of an internal entity.
.. data:: XML_ERROR_BAD_CHAR_REF
A character reference referred to a character which is illegal in XML (for
example, character ``0``, or '``&#0;``').
.. data:: XML_ERROR_BINARY_ENTITY_REF
An entity reference referred to an entity which was declared with a notation, so
cannot be parsed.
.. data:: XML_ERROR_DUPLICATE_ATTRIBUTE
An attribute was used more than once in a start tag.
.. data:: XML_ERROR_INCORRECT_ENCODING
.. data:: XML_ERROR_INVALID_TOKEN
Raised when an input byte could not properly be assigned to a character; for
example, a NUL byte (value ``0``) in a UTF-8 input stream.
.. data:: XML_ERROR_JUNK_AFTER_DOC_ELEMENT
Something other than whitespace occurred after the document element.
.. data:: XML_ERROR_MISPLACED_XML_PI
An XML declaration was found somewhere other than the start of the input data.
.. data:: XML_ERROR_NO_ELEMENTS
The document contains no elements (XML requires all documents to contain exactly
one top-level element)..
.. data:: XML_ERROR_NO_MEMORY
Expat was not able to allocate memory internally.
.. data:: XML_ERROR_PARAM_ENTITY_REF
A parameter entity reference was found where it was not allowed.
.. data:: XML_ERROR_PARTIAL_CHAR
An incomplete character was found in the input.
.. data:: XML_ERROR_RECURSIVE_ENTITY_REF
An entity reference contained another reference to the same entity; possibly via
a different name, and possibly indirectly.
.. data:: XML_ERROR_SYNTAX
Some unspecified syntax error was encountered.
.. data:: XML_ERROR_TAG_MISMATCH
An end tag did not match the innermost open start tag.
.. data:: XML_ERROR_UNCLOSED_TOKEN
Some token (such as a start tag) was not closed before the end of the stream or
the next token was encountered.
.. data:: XML_ERROR_UNDEFINED_ENTITY
A reference was made to a entity which was not defined.
.. data:: XML_ERROR_UNKNOWN_ENCODING
The document encoding is not supported by Expat.
.. data:: XML_ERROR_UNCLOSED_CDATA_SECTION
A CDATA marked section was not closed.
.. data:: XML_ERROR_EXTERNAL_ENTITY_HANDLING
.. data:: XML_ERROR_NOT_STANDALONE
The parser determined that the document was not "standalone" though it declared
itself to be in the XML declaration, and the :attr:`NotStandaloneHandler` was
set and returned ``0``.
.. data:: XML_ERROR_UNEXPECTED_STATE
.. data:: XML_ERROR_ENTITY_DECLARED_IN_PE
.. data:: XML_ERROR_FEATURE_REQUIRES_XML_DTD
An operation was requested that requires DTD support to be compiled in, but
Expat was configured without DTD support. This should never be reported by a
standard build of the :mod:`xml.parsers.expat` module.
.. data:: XML_ERROR_CANT_CHANGE_FEATURE_ONCE_PARSING
A behavioral change was requested after parsing started that can only be changed
before parsing has started. This is (currently) only raised by
:meth:`UseForeignDTD`.
.. data:: XML_ERROR_UNBOUND_PREFIX
An undeclared prefix was found when namespace processing was enabled.
.. data:: XML_ERROR_UNDECLARING_PREFIX
The document attempted to remove the namespace declaration associated with a
prefix.
.. data:: XML_ERROR_INCOMPLETE_PE

includes attempts to provide additional input or to stop the parser.
.. data:: XML_ERROR_NOT_SUSPENDED
An attempt to resume the parser was made when the parser had not been suspended.
.. data:: XML_ERROR_ABORTED
This should not be reported to Python applications.
.. data:: XML_ERROR_FINISHED
The requested operation was made on a parser which was finished parsing input,
but isn't allowed. This includes attempts to provide additional input or to
stop the parser.
.. data:: XML_ERROR_SUSPEND_PE

Fixes issue #1779871. ........ r61439 | martin.v.loewis | 2008-03-17 17:31:57 +0100 (Mo, 17 Mär 2008) | 2 lines Add Trent Nelson. ........ r61444 | travis.oliphant | 2008-03-17 18:36:12 +0100 (Mo, 17 Mär 2008) | 1 line Add necessary headers to back-port new buffer protocol to Python 2.6 ........ r61449 | gregory.p.smith | 2008-03-17 19:48:05 +0100 (Mo, 17 Mär 2008) | 8 lines Force zlib.crc32 and zlib.adler32 to return a signed integer on all platforms regardless of the native sizeof(long) used in the integer object.
