openSUSE Recommended Update: python-lxml: Updated to 3.1.0 ______________________________________________________________________________ Announcement ID: openSUSE-RU-2013:0583-1 Rating: important References: #798292 Affected Products: openSUSE 12.3 ______________________________________________________________________________ An update that has one recommended fix can now be installed. Description: This update fixes the following issues for python-lxml: - Updated to 3.1.0 to fix bnc#798292. The previous version is not usable with python3 + fixes since 2.3.4: + 3.1.0 (2013-02-10): + Features added: + lxml.html.clean allows overriding the set of attributes that it considers 'safe'. + Bugs fixed + copy.copy(el.attrib) raised an exception. It now returns a copy of the attributes as a plain Python dict. + When used with namespace prefixes, the el.find*() methods always used the first namespace mapping that was provided for each path expression instead of using the one that was actually passed in for the current run. + Fix undefined C symbol in Python runtimes compiled without threading support. + 3.1beta1 (2012-12-21): + Features added + New build-time option --with-unicode-strings for Python 2 that makes the API always return Unicode strings for names and text instead of byte strings for plain ASCII content. + New incremental XML file writing API etree.xmlfile(). + E factory in lxml.objectify is callable to simplify the creation of tags with non-identifier names without having to resort to getattr(). + Bugs fixed + When starting from a non-namespaced element in lxml.objectify, searching for a child without explicitly specifying a namespace incorrectly found namespaced elements with the requested local name, instead of restricting the search to non-namespaced children. + Deprecation warnings were fixed for Python 3.x. + lxml.html.fromstring() failed to accept bytes input in Py3. + Static build of libxml2 2.9.0 failed due to missing file. + Other changes + The externally useless class _ObjectifyElementMakerCaller was removed from the module API of lxml.objectify. + lxml.builder is faster for adding text to elements with many children. + 3.0.2 (2012-12-14): + Features added + Bugs fixed + Fix crash during interpreter shutdown by switching to Cython 0.17.3 for building. + 3.0.1 (2012-10-14): + Bugs fixed + Element proxies could disappear during garbage collection in PyPy without proper cleanup. + Failure to work with libxml2 2.6.x. + static MacOS-X build failed in Py3. + 3.0 (2012-10-08): + Bugs fixed + End-of-file handling was incorrect in iterparse() when reading from a low-level C file stream and failed in libxml2 2.9.0 due to its improved consistency checks. + Other changes + The build no longer uses Cython by default unless the generated C files are missing. To use Cython, pass the option "--with-cython". To ignore the fatal build error when Cython is required but not available (e.g. to run special setup.py commands that do not actually run a build), pass "--without-cython". + 3.0beta1 (2012-09-26): + Features added + Python level access to (optional) libxml2 memory debugging features to simplify debugging of memory leaks etc. + Bugs fixed + Fix a memory leak in XPath by switching to Cython 0.17.1. + Some tests were adapted to work with PyPy. + Other changes + The code was adapted to work with the upcoming libxml2 2.9.0 release. + 3.0alpha2 (2012-08-23): + Features added + The .iter() method of elements now accepts tag arguments like "{*}name" to search for elements with a given local name in any namespace. With this addition, all combinations of wildcards now work as expected: "{ns}name", "{}name", "{*}name", "{ns}*", "{}*" and "{*}*". Note that "name" is equivalent to "{}name", but "*" is "{*}*". The same change applies to the .getiterator(), .itersiblings(), .iterancestors(), .iterdescendants(), .iterchildren() and .itertext() methods;the strip_attributes(), strip_elements() and strip_tags() functions as well as the iterparse() class. + C14N allows specifying the inclusive prefixes to be promoted to top-level during exclusive serialisation. + Bugs fixed + Passing long Unicode strings into the feed() parser interface failed to read the entire string. + 3.0alpha1 (2012-07-31): + Features added + Initial support for building in PyPy (through cpyext). + DTD objects gained an API that allows read access to their declarations. + xpathgrep.py gained support for parsing line-by-line (e.g. from grep output) and for surrounding the output with a new root tag. + E-factory in lxml.builder accepts subtypes of known data types (such as string subtypes) when building elements around them. + Tree iteration and iterparse() with a selective tag argument supports passing a set of tags. Tree nodes will be returned by the iterators if they match any of the tags. + Bugs fixed + The .find*() methods in lxml.objectify no longer use XPath internally, which makes them faster in many cases (especially when short circuiting after a single or couple of elements) and fixes some behavioural differences compared to lxml.etree. Note that this means that they no longer support arbitrary XPath expressions but only the subset that the ElementPath language supports. The previous implementation was also redundant with the normal XPath support, which can be used as a replacement. + el.find('*') could accidentally return a comment or processing instruction that happened to be in the wrong spot. (Same for the other .find*() methods.) + The error logging is less intrusive and avoids a global setup where possible. + Fixed undefined names in html5lib parser. + xpathgrep.py did not work in Python 3. + Element.attrib.update() did not accept an attrib of another Element as parameter. + For subtypes of ElementBase that make the .text or .tail properties immutable (as in objectify, for example), inserting text when creating Elements through the E-Factory feature of the class constructor would fail with an exception, stating that the text cannot be modified. + Other changes + The code base was overhauled to properly use 'const' where the API of libxml2 and libxslt requests it. This also has an impact on the public C-API of lxml itself, as defined in etreepublic.pxd, as well as the provided declarations in the lxml/includes/ directory. Code that uses these declarations may have to be adapted. On the plus side, this fixes several C compiler warnings, also for user code, thus making it easier to spot real problems again. + The functionality of "lxml.cssselect" was moved into a separate PyPI package called "cssselect". To continue using it, you must install that package separately. The "lxml.cssselect" module is still available and provides the same interface, provided the "cssselect" package can be imported at runtime. + Element attributes passed in as an attrib dict or as keyword arguments are now sorted by (namespaced) name before being created to make their order predictable for serialisation and iteration. Note that adding or deleting attributes afterwards does not take that order into account, i.e. setting a new attribute appends it after the existing ones. + Several classes that are for internal use only were removed from the lxml.etree module dict: _InputDocument, _ResolverRegistry, _ResolverContext, _BaseContext, _ExsltRegExp, _IterparseContext, _TempStore, _ExceptionContext, __ContentOnlyElement, _AttribIterator, _NamespaceRegistry, _ClassNamespaceRegistry, _FunctionNamespaceRegistry, _XPathFunctionNamespaceRegistry, _ParserDictionaryContext, _FileReaderContext, _ParserContext, _PythonSaxParserTarget, _TargetParserContext, _ReadOnlyProxy, _ReadOnlyPIProxy, _ReadOnlyEntityProxy, _ReadOnlyElementProxy, _OpaqueNodeWrapper, _OpaqueDocumentWrapper, _ModifyContentOnlyProxy, _ModifyContentOnlyPIProxy, _ModifyContentOnlyEntityProxy, _AppendOnlyElementProxy, _SaxParserContext, _FilelikeWriter, _ParserSchemaValidationContext, _XPathContext, _XSLTResolverContext, _XSLTContext, _XSLTQuotedStringParam + Several internal classes can no longer be inherited from: _InputDocument, _ResolverRegistry, _ExsltRegExp, _ElementUnicodeResult, _IterparseContext, _TempStore, _AttribIterator, _ClassNamespaceRegistry, _XPathFunctionNamespaceRegistry, _ParserDictionaryContext, _FileReaderContext, _PythonSaxParserTarget, _TargetParserContext, _ReadOnlyPIProxy, _ReadOnlyEntityProxy, _OpaqueDocumentWrapper, _ModifyContentOnlyPIProxy, _ModifyContentOnlyEntityProxy, _AppendOnlyElementProxy, _FilelikeWriter, _ParserSchemaValidationContext, _XPathContext, _XSLTResolverContext, _XSLTContext, _XSLTQuotedStringParam, _XSLTResultTree, _XSLTProcessingInstruction + 2.3.6 (2012-09-28): + Bugs fixed + Passing long Unicode strings into the feed() parser interface failed to read the entire string. + 2.3.5 (2012-07-31): + Bugs fixed + Crash when merging text nodes in element.remove(). + Crash in sax/target parser when reporting empty doctype.
