Update lxml from 4.2.6 to 4.3.1.

Changelog ### 4.3.1 ``` ================== * LP1814522: Crash when appending a child subtree that contains unsubstituted entity references. ``` ### 4.3.0 ``` ================== Features added -------------- * The module ``lxml.sax`` is compiled using Cython in order to speed it up. * GH267: ``lxml.sax.ElementTreeProducer`` now preserves the namespace prefixes. If two prefixes point to the same URI, the first prefix in alphabetical order is used. Patch by Lennart Regebro. * Updated ISO-Schematron implementation to 2013 version (now MIT licensed) and the corresponding schema to the 2016 version (with optional "properties"). Other changes ------------- * GH270, GH271: Support for Python 2.6 and 3.3 was removed. Patch by hugovk. * The minimum dependency versions were raised to libxml2 2.9.2 and libxslt 1.1.27, which were released in 2014 and 2012 respectively. * Built with Cython 0.29.2. ``` ### 4.2.6 ``` ================== Bugs fixed ---------- * LP1799755: Fix a DeprecationWarning in Py3.7+. * Import warnings in Python 3.6+ were resolved. ``` ### 4.2.5 ``` ================== Bugs fixed ---------- * Javascript URLs that used URL escaping were not removed by the HTML cleaner. Security problem found by Omar Eissa. (CVE-2018-19787) ``` ### 4.2.4 ``` ================== Features added -------------- * GH259: Allow using ``pkg-config`` for build configuration. Patch by Patrick Griffis. Bugs fixed ---------- * LP1773749, GH268: Crash when moving an element to another document with ``Element.insert()``. Patch by Alexander Weggerle. ``` ### 4.2.3 ``` ================== Bugs fixed ---------- * Reverted GH265: lxml links against zlib as a shared library again. ``` ### 4.2.2 ``` ================== Bugs fixed ---------- * GH266: Fix sporadic crash during GC when parse-time schema validation is used and the parser participates in a reference cycle. Original patch by Julien Greard. * GH265: lxml no longer links against zlib as a shared library, only on static builds. Patch by Nehal J Wani. ``` ### 4.2.1 ``` ================== Bugs fixed ---------- * LP1755825: ``iterwalk()`` failed to return the 'start' event for the initial element if a tag selector is used. * LP1756314: Failure to import 4.2.0 into PyPy due to a missing library symbol. * LP1727864, GH258: Add "-isysroot" linker option on MacOS as needed by XCode 9. ``` ### 4.2.0 ``` ================== Features added -------------- * GH255: ``SelectElement.value`` returns more standard-compliant and browser-like defaults for non-multi-selects. If no option is selected, the value of the first option is returned (instead of None). If multiple options are selected, the value of the last one is returned (instead of that of the first one). If no options are present (not standard-compliant) ``SelectElement.value`` still returns ``None``. * GH261: The ``HTMLParser()`` now supports the ``huge_tree`` option. Patch by stranac. Bugs fixed ---------- * LP1551797: Some XSLT messages were not captured by the transform error log. * LP1737825: Crash at shutdown after an interrupted iterparse run with XMLSchema validation. Other changes ------------- ``` ### 4.1.1 ``` ================== * Rebuild with Cython 0.27.3 to improve support for Py3.7. ``` ### 4.1.0 ``` ================== Features added -------------- * ElementPath supports text predicates for current node, like "[.='text']". * ElementPath allows spaces in predicates. * Custom Element classes and XPath functions can now be registered with a decorator rather than explicit dict assignments. * Static Linux wheels are now built with link time optimisation (LTO) enabled. This should have a beneficial impact on the overall performance by providing a tighter compiler integration between lxml and libxml2/libxslt. Bugs fixed ---------- * LP1722776: Requesting non-Element objects like comments from a document with ``PythonElementClassLookup`` could fail with a TypeError. ``` ### 4.0.0 ``` ================== Features added -------------- * The ElementPath implementation is now compiled using Cython, which speeds up the ``.find*()`` methods quite significantly. * The modules ``lxml.builder``, ``lxml.html.diff`` and ``lxml.html.clean`` are also compiled using Cython in order to speed them up. * ``xmlfile()`` supports async coroutines using ``async with`` and ``await``. * ``iterwalk()`` has a new method ``skip_subtree()`` that prevents walking into the descendants of the current element. * ``RelaxNG.from_rnc_string()`` accepts a ``base_url`` argument to allow relative resource lookups. * The XSLT result object has a new method ``.write_output(file)`` that serialises output data into a file according to the ``<xsl:output>`` configuration. Bugs fixed ---------- * GH251: HTML comments were handled incorrectly by the soupparser. Patch by mozbugbox. * LP1654544: The html5parser no longer passes the ``useChardet`` option if the input is a Unicode string, unless explicitly requested. When parsing files, the default is to enable it when a URL or file path is passed (because the file is then opened in binary mode), and to disable it when reading from a file(-like) object. Note: This is a backwards incompatible change of the default configuration. If your code parses byte strings/streams and depends on character detection, please pass the option ``guess_charset=True`` explicitly, which already worked in older lxml versions. * LP1703810: ``etree.fromstring()`` failed to parse UTF-32 data with BOM. * LP1526522: Some RelaxNG errors were not reported in the error log. * LP1567526: Empty and plain text input raised a TypeError in soupparser. * LP1710429: Uninitialised variable usage in HTML diff. * LP1415643: The closing tags context manager in ``xmlfile()`` could continue to output end tags even after writing failed with an exception. * LP1465357: ``xmlfile.write()`` now accepts and ignores None as input argument. * Compilation under Py3.7-pre failed due to a modified function signature. Other changes ------------- * The main module source files were renamed from ``lxml.*.pyx`` to plain ``*.pyx`` (e.g. ``etree.pyx``) to simplify their handling in the build process. Care was taken to keep the old header files as fallbacks for code that compiles against the public C-API of lxml, but it might still be worth validating that third-party code does not notice this change. ``` ### 3.8.0 ``` ================== Features added -------------- * ``ElementTree.write()`` has a new option ``doctype`` that writes out a doctype string before the serialisation, in the same way as ``tostring()``. * GH220: ``xmlfile`` allows switching output methods at an element level. Patch by Burak Arslan. * LP1595781, GH240: added a PyCapsule Python API and C-level API for passing externally generated libxml2 documents into lxml. * GH244: error log entries have a new property ``path`` with an XPath expression (if known, None otherwise) that points to the tree element responsible for the error. Patch by Bob Kline. * The namespace prefix mapping that can be used in ElementPath now injects a default namespace when passing a None prefix. Bugs fixed ---------- * GH238: Character escapes were not hex-encoded in the ``xmlfile`` serialiser. Patch by matejcik. * GH229: fix for externally created XML documents. Patch by Theodore Dubois. * LP1665241, GH228: Form data handling in lxml.html no longer strips the option values specified in form attributes but only the text values. Patch by Ashish Kulkarni. * LP1551797: revert previous fix for XSLT error logging as it breaks multi-threaded XSLT processing. * LP1673355, GH233: ``fromstring()`` html5parser failed to parse byte strings. Other changes ------------- * The previously undocumented ``docstring`` option in ``ElementTree.write()`` produces a deprecation warning and will eventually be removed. ``` ### 3.7.4 ``` ================== Bugs fixed ---------- * LP1551797: revert previous fix for XSLT error logging as it breaks multi-threaded XSLT processing. * LP1673355, GH233: ``fromstring()`` html5parser failed to parse byte strings. ``` ### 3.7.3 ``` ================== Bugs fixed ---------- * GH218 was ineffective in Python 3. * GH222: ``lxml.html.submit_form()`` failed in Python 3. Patch by Jakub Wilk. ``` ### 3.7.2 ``` ================== * GH220: ``xmlfile`` allows switching output methods at an element level. Patch by Burak Arslan. Bugs fixed ---------- * Work around installation problems in recent Python 2.7 versions due to FTP download failures. * GH219: ``xmlfile.element()`` was not properly quoting attribute values. Patch by Burak Arslan. * GH218: ``xmlfile.element()`` was not properly escaping text content of script/style tags. Patch by Burak Arslan. ``` ### 3.7.1 ``` ================== * No source changes, issued only to solve problems with the binary packages released for 3.7.0. ``` ### 3.7.0 ``` ================== Features added -------------- * GH217: ``XMLSyntaxError`` now behaves more like its ``SyntaxError`` baseclass. Patch by Philipp A. * GH216: ``HTMLParser()`` now supports the same ``collect_ids`` parameter as ``XMLParser()``. Patch by Burak Arslan. * GH210: Allow specifying a serialisation method in ``xmlfile.write()``. Patch by Burak Arslan. * GH203: New option ``default_doctype`` in ``HTMLParser`` that allows disabling the automatic doctype creation. Patch by Shadab Zafar. * GH201: Calling the method ``.set('attrname')`` without value argument (or ``None``) on HTML elements creates an attribute without value that serialises like ``<div attrname></div>``. Patch by Daniel Holth. * GH197: Ignore form input fields in ``form_values()`` when they are marked as ``disabled`` in HTML. Patch by Kristian Klemon. Bugs fixed ---------- * GH206: File name and line number were missing from XSLT error messages. Patch by Marcus Brinkmann. Other changes ------------- * Log entries no longer allow anything but plain string objects as message text and file name. * ``zlib`` is included in the list of statically built libraries. ``` ### 3.6.4 ``` ================== * GH204, LP1614693: build fix for MacOS-X. ``` ### 3.6.3 ``` ================== * LP1614603: change linker flags to build multi-linux wheels ``` ### 3.6.2 ``` ================== * LP1614603: release without source changes to provide cleanly built Linux wheels ``` ### 3.6.1 ``` ================== Features added -------------- * GH180: Separate option ``inline_style`` for Cleaner that only removes ``style`` attributes instead of all styles. Patch by Christian Pedersen. * GH196: Windows build support for Python 3.5. Contribution by Maximilian Hils. Bugs fixed ---------- * GH199: Exclude ``file`` fields from ``FormElement.form_values`` (as browsers do). Patch by Tomas Divis. * GH198, LP1568167: Try to provide base URL from ``Resolver.resolve_string()``. Patch by Michael van Tellingen. * GH191: More accurate float serialisation in ``objectify.FloatElement``. Patch by Holger Joukl. * LP1551797: Repair XSLT error logging. Patch by Marcus Brinkmann. ``` ### 3.6.0 ``` ================== Features added -------------- * GH187: Now supports (only) version 5.x and later of PyPy. Patch by Armin Rigo. * GH181: Direct support for ``.rnc`` files in `RelaxNG()` if ``rnc2rng`` is installed. Patch by Dirkjan Ochtman. Bugs fixed ---------- * GH189: Static builds honour FTP proxy configurations when downloading the external libs. Patch by Youhei Sakurai. * GH186: Soupparser failed to process entities in Python 3.x. Patch by Duncan Morris. * GH185: Rare encoding related ``TypeError`` on import was fixed. Patch by Petr Demin. ``` ### 3.5.0 ``` ================== Bugs fixed ---------- * Unicode string results failed XPath queries in PyPy. * LP1497051: HTML target parser failed to terminate on exceptions and continued parsing instead. * Deprecated API usage in doctestcompare. ``` ### 3.5.0b1 ``` ==================== Features added -------------- * ``cleanup_namespaces()`` accepts a new argument ``keep_ns_prefixes`` that does not remove definitions of the provided prefix-namespace mapping from the tree. * ``cleanup_namespaces()`` accepts a new argument ``top_nsmap`` that moves definitions of the provided prefix-namespace mapping to the top of the tree. * LP1490451: ``Element`` objects gained a ``cssselect()`` method as known from ``lxml.html``. Patch by Simon Sapin. * API functions and methods behave and look more like Python functions, which allows introspection on them etc. One side effect to be aware of is that the functions now bind as methods when assigned to a class variable. A quick fix is to wrap them in ``staticmethod()`` (as for normal Python functions). * ISO-Schematron support gained an option ``error_finder`` that allows passing a filter function for picking validation errors from reports. * LP1243600: Elements in ``lxml.html`` gained a ``classes`` property that provides a set-like interface to the ``class`` attribute. Original patch by masklinn. * LP1341964: The soupparser now handles DOCTYPE declarations, comments and processing instructions outside of the root element. Patch by Olli Pottonen. * LP1421512: The ``docinfo`` of a tree was made editable to allow setting and removing the public ID and system ID of the DOCTYPE. Patch by Olli Pottonen. * LP1442427: More work-arounds for quirks and bugs in pypy and pypy3. * ``lxml.html.soupparser`` now uses BeautifulSoup version 4 instead of version 3 if available. Bugs fixed ---------- * Memory errors that occur during tree adaptations (e.g. moving subtrees to foreign documents) could leave the tree in a crash prone state. * Calling ``process_children()`` in an XSLT extension element without an ``output_parent`` argument failed with a ``TypeError``. Fix by Jens Tröger. * GH162: Image data in HTML ``data`` URLs is considered safe and no longer removed by ``lxml.html.clean`` JavaScript cleaner. * GH166: Static build could link libraries in wrong order. * GH172: Rely a bit more on libxml2 for encoding detection rather than rolling our own in some cases. Patch by Olli Pottonen. * GH159: Validity checks for names and string content were tightened to detect the use of illegal characters early. Patch by Olli Pottonen. * LP1421921: Comments/PIs before the DOCTYPE declaration were not serialised. Patch by Olli Pottonen. * LP659367: Some HTML DOCTYPE declarations were not serialised. Patch by Olli Pottonen. * LP1238503: lxml.doctestcompare is now consistent with stdlib's doctest in how it uses ``+`` and ``-`` to refer to unexpected and missing output. * Empty prefixes are explicitly rejected when a namespace mapping is used with ElementPath to avoid hiding bugs in user code. * Several problems with PyPy were fixed by switching to Cython 0.23. ``` ### 3.4.4 ``` ================== Bugs fixed ---------- * An ElementTree compatibility test added in lxml 3.4.3 that failed in Python 3.4+ was removed again. ``` ### 3.4.3 ``` ================== Bugs fixed ---------- * Expression cache in ElementPath was ignored. Fix by Changaco. * LP1426868: Passing a default namespace and a prefixed namespace mapping as nsmap into ``xmlfile.element()`` raised a ``TypeError``. * LP1421927: DOCTYPE system URLs were incorrectly quoted when containing double quotes. Patch by Olli Pottonen. * LP1419354: meta-redirect URLs were incorrectly processed by ``iterlinks()`` if preceded by whitespace. ``` ### 3.4.2 ``` ================== Bugs fixed ---------- * LP1415907: Crash when creating an XMLSchema from a non-root element of an XML document. * LP1369362: HTML cleaning failed when hitting processing instructions with pseudo-attributes. * ``CDATA()`` wrapped content was rejected for tail text. * CDATA sections were not serialised as tail text of the top-level element. ``` ### 3.4.1 ``` ================== Features added -------------- * New ``htmlfile`` HTML generator to accompany the incremental ``xmlfile`` serialisation API. Patch by Burak Arslan. Bugs fixed ---------- * ``lxml.sax.ElementTreeContentHandler`` did not initialise its superclass. ``` ### 3.4.0 ``` ================== Features added -------------- * ``xmlfile(buffered=False)`` disables output buffering and flushes the content after each API operation (starting/ending element blocks or writes). A new method ``xf.flush()`` can alternatively be used to explicitly flush the output. * ``lxml.html.document_fromstring`` has a new option ``ensure_head_body=True`` which will add an empty head and/or body element to the result document if missing. * ``lxml.html.iterlinks`` now returns links inside meta refresh tags. * New ``XMLParser`` option ``collect_ids=False`` to disable ID hash table creation. This can substantially speed up parsing of documents with many different IDs that are not used. * The parser uses per-document hash tables for XML IDs. This reduces the load of the global parser dict and speeds up parsing for documents with many different IDs. * ``ElementTree.getelementpath(element)`` returns a structural ElementPath expression for the given element, which can be used for lookups later. * ``xmlfile()`` accepts a new argument ``close=True`` to close file(-like) objects after writing to them. Before, ``xmlfile()`` only closed the file if it had opened it internally. * Allow "bytearray" type for ASCII text input. Bugs fixed ---------- Other changes ------------- * LP400588: decoding errors have become hard errors even in recovery mode. Previously, they could lead to an internal tree representation in a mixed encoding state, which lead to very late errors or even silently incorrect behaviour during tree traversal or serialisation. * Requires Python 2.6, 2.7, 3.2 or later. No longer supports Python 2.4, 2.5 and 3.1, use lxml 3.3.x for those. * Requires libxml2 2.7.0 or later and libxslt 1.1.23 or later, use lxml 3.3.x with older versions. ``` ### 3.3.6 ``` ================== Bugs fixed ---------- * Prevent tree cycle creation when adding Elements as siblings. * LP1361948: crash when deallocating Element siblings without parent. * LP1354652: crash when traversing internally loaded documents in XSLT extension functions. ``` ### 3.3.5 ``` ================== Bugs fixed ---------- * HTML cleaning could fail to strip javascript links that mix control characters into the link scheme. ``` ### 3.3.4 ``` ================== Features added -------------- * Source line numbers above 65535 are available on Elements when using libxml2 2.9 or later. Bugs fixed ---------- * ``lxml.html.fragment_fromstring()`` failed for bytes input in Py3. Other changes ------------- ``` ### 3.3.3 ``` ================== Bugs fixed ---------- * LP1287118: Crash when using Element subtypes with ``__slots__``. Other changes ------------- * The internal classes ``_LogEntry`` and ``_Attrib`` can no longer be subclassed from Python code. ``` ### 3.3.2 ``` ================== Bugs fixed ---------- * The properties ``resolvers`` and ``version``, as well as the methods ``set_element_class_lookup()`` and ``makeelement()``, were lost from ``iterparse`` objects in 3.3.0. * LP1222132: instances of ``XMLSchema``, ``Schematron`` and ``RelaxNG`` did not clear their local ``error_log`` before running a validation. * LP1238500: lxml.doctestcompare mixed up "expected" and "actual" in attribute values. * Some file I/O tests were failing in MS-Windows due to non-portable temp file usage. Initial patch by Gabi Davar. * LP910014: duplicate IDs in a document were not reported by DTD validation. * LP1185332: ``tostring(method="html")`` did not use HTML serialisation semantics for trailing tail text. Initial patch by Sylvain Viollon. * LP1281139: ``.attrib`` value of Comments lost its mutation methods in 3.3.0. Even though it is empty and immutable, it should still provide the same interface as that returned for Elements. ``` ### 3.3.1 ``` ================== Features added -------------- Bugs fixed ---------- * LP1014290: HTML documents parsed with ``parser.feed()`` failed to find elements during tag iteration. * LP1273709: Building in PyPy failed due to missing support for ``PyUnicode_Compare()`` and ``PyByteArray_*()`` in PyPy's C-API. * LP1274413: Compilation in MSVC failed due to missing "stdint.h" standard header file. * LP1274118: iterparse() failed to parse BOM prefixed files. Other changes ------------- ``` ### 3.3.0 ``` ================== Features added -------------- Bugs fixed ---------- * The heuristic that distinguishes file paths from URLs was tightened to produce less false negatives. Other changes ------------- ``` ### 3.3.0beta5 ``` ======================= Features added -------------- * The PEP 393 unicode parsing support gained a fallback for wchar strings which might still be somewhat common on Windows systems. Bugs fixed ---------- * Several error handling problems were fixed throughout the code base that could previously lead to exceptions being silently swallowed or not properly reported. * The C-API function ``appendChild()`` is now deprecated as it does not propagate exceptions (its return type is ``void``). The new function ``appendChildToElement()`` was added as a safe replacement. * Passing a string into ``fromstringlist()`` raises an exception instead of parsing the string character by character. Other changes ------------- * Document cleanup code was simplified using the new GC features in Cython 0.20. ``` ### 3.3.0beta4 ``` ======================= Features added -------------- Bugs fixed ---------- * The (empty) value returned by the ``attrib`` property of Entity and Comment objects was mutable. * Element class lookup wasn't available for the new pull parsers or when using a custom parser target. * Setting Element attributes on instantiation with both the ``attrib`` argument and keyword arguments could modify the mapping passed as ``attrib``. * LP1266171: DTDs instantiated from internal/external subsets (i.e. through the docinfo property) lost their attribute declarations. Other changes ------------- * Built with Cython 0.20pre (gitrev 012ae82eb) to prepare support for Python 3.4. ``` ### 3.3.0beta3 ``` ======================= Features added -------------- * Unicode string parsing was optimised for Python 3.3 (PEP 393). Bugs fixed ---------- * HTML parsing of Unicode strings could misdecode the input on some platforms. * Crash in xmlfile() when closing open elements out of order in an error case. Other changes ------------- ``` ### 3.3.0beta2 ``` ======================= Features added -------------- * ``iterparse()`` supports the ``recover`` option. Bugs fixed ---------- * Crash in ``iterparse()`` for HTML parsing. * Crash in target parsing with attributes. Other changes ------------- * The safety check in the read-only tree implementation (e.g. used by ``PythonElementClassLookup``) raises a more appropriate ``ReferenceError`` for illegal access after tree disposal instead of an ``AssertionError``. This should only impact test code that specifically checks the original behaviour. ``` ### 3.3.0beta1 ``` ======================= Features added -------------- * New option ``handle_failures`` in ``make_links_absolute()`` and ``resolve_base_href()`` (lxml.html) that enables ignoring or discarding links that fail to parse as URLs. * New parser classes ``XMLPullParser`` and ``HTMLPullParser`` for incremental parsing, as implemented for ElementTree in Python 3.4. * ``iterparse()`` enables recovery mode by default for HTML parsing (``html=True``). Bugs fixed ---------- * LP1255132: crash when trying to run validation over non-Element (e.g. comment or PI). * Error messages in the log and in exception messages that originated from libxml2 could accidentally be picked up from preceding warnings instead of the actual error. * The ``ElementMaker`` in lxml.objectify did not accept a dict as argument for adding attributes to the element it's building. This works as in lxml.builder now. * LP1228881: ``repr(XSLTAccessControl)`` failed in Python 3. * Raise ``ValueError`` when trying to append an Element to itself or to one of its own descendants, instead of running into an infinite loop. * LP1206077: htmldiff discarded whitespace from the output. * Compressed plain-text serialisation to file-like objects was broken. * lxml.html.formfill: Fix textarea form filling. The textarea used to be cleared before the new content was set, which removed the name attribute. Other changes ------------- * Some basic API classes use freelists internally for faster instantiation. This can speed up some ``iterparse()`` scenarios, for example. * ``iterparse()`` was rewritten to use the new ``*PullParser`` classes internally instead of being a parser itself. ``` ### 3.2.5 ``` ================== Features added -------------- Bugs fixed ---------- * Crash in xmlfile() when closing open elements out of order in an error case. * Crash in target parsing with attributes. * LP1255132: crash when trying to run validation over non-Element (e.g. comment or PI). Other changes ------------- ``` ### 3.2.4 ``` ================== Features added -------------- Bugs fixed ---------- * Memory leak when creating an XPath evaluator in a thread. * LP1228881: ``repr(XSLTAccessControl)`` failed in Python 3. * Raise ``ValueError`` when trying to append an Element to itself or to one of its own descendants. * LP1206077: htmldiff discarded whitespace from the output. * Compressed plain-text serialisation to file-like objects was broken. Other changes ------------- ``` ### 3.2.3 ``` ================== Bugs fixed ---------- * Fix support for Python 2.4 which was lost in 3.2.2. ``` ### 3.2.2 ``` ================== Features added -------------- Bugs fixed ---------- * LP1185701: spurious XMLSyntaxError after finishing iterparse(). * Crash in lxml.objectify during xsi annotation. Other changes ------------- * Return values of user provided element class lookup methods are now validated against the type of the XML node they represent to prevent API class mismatches. ``` ### 3.2.1 ``` ================== Features added -------------- * The methods ``apply_templates()`` and ``process_children()`` of XSLT extension elements have gained two new boolean options ``elements_only`` and ``remove_blank_text`` that discard either all strings or whitespace-only strings from the result list. Bugs fixed ---------- * When moving Elements to another tree, the namespace cleanup mechanism no longer drops namespace prefixes from attributes for which it finds a default namespace declaration, to prevent them from appearing as unnamespaced attributes after serialisation. * Returning non-type objects from a custom class lookup method could lead to a crash. * Instantiating and using subtypes of Comments and ProcessingInstructions crashed. Other changes ------------- ``` ### 3.2.0 ``` ================== Features added -------------- Bugs fixed ---------- * LP690319: Leading whitespace could change the behaviour of the string parsing functions in ``lxml.html``. * LP599318: The string parsing functions in ``lxml.html`` are more robust in the face of uncommon HTML content like framesets or missing body tags. Patch by Stefan Seelmann. * LP712941: I/O errors while trying to access files with paths that contain non-ASCII characters could raise ``UnicodeDecodeError`` instead of properly reporting the ``IOError``. * LP673205: Parsing from in-memory strings disabled network access in the default parser and made subsequent attempts to parse from a URL fail. * LP971754: lxml.html.clean appends 'nofollow' to 'rel' attributes instead of overwriting the current value. * LP715687: lxml.html.clean no longer discards scripts that are explicitly allowed by the user provided whitelist. Patch by Christine Koppelt. Other changes ------------- ``` ### 3.1.2 ``` ================== Features added -------------- Bugs fixed ---------- * LP1136509: Passing attributes through the namespace-unaware API of the sax bridge (i.e. the ``handler.startElement()`` method) failed with a ``TypeError``. Patch by Mike Bayer. * LP1123074: Fix serialisation error in XSLT output when converting the result tree to a Unicode string. * GH105: Replace illegal usage of ``xmlBufLength()`` in libxml2 2.9.0 by properly exported API function ``xmlBufUse()``. Other changes ------------- ``` ### 3.1.1 ``` ================== Features added -------------- Bugs fixed ---------- * LP1160386: Write access to ``lxml.html.FormElement.fields`` raised an AttributeError in Py3. * Illegal memory access during cleanup in incremental xmlfile writer. Other changes ------------- * The externally useless class ``lxml.etree._BaseParser`` was removed from the module dict. ``` ### 3.1.0 ``` ================== Features added -------------- * GH89: lxml.html.clean allows overriding the set of attributes that it considers 'safe'. Patch by Francis Devereux. Bugs fixed ---------- * LP1104370: ``copy.copy(el.attrib)`` raised an exception. It now returns a copy of the attributes as a plain Python dict. * GH95: 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. * LP1092521, GH91: Fix undefined C symbol in Python runtimes compiled without threading support. Patch by Ulrich Seidl. Other changes ------------- ``` ### 3.1beta1 ``` ===================== 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. * GH85: Deprecation warnings were fixed for Python 3.x. * GH33: lxml.html.fromstring() failed to accept bytes input in Py3. * LP1080792: 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. * LP1075622: lxml.builder is faster for adding text to elements with many children. Patch by Anders Hammarquist. ``` ### 3.0.2 ``` ================== Features added -------------- Bugs fixed ---------- * Fix crash during interpreter shutdown by switching to Cython 0.17.3 for building. Other changes ------------- ``` ### 3.0.1 ``` ================== Features added -------------- Bugs fixed ---------- * LP1065924: Element proxies could disappear during garbage collection in PyPy without proper cleanup. * GH71: Failure to work with libxml2 2.6.x. * LP1065139: static MacOS-X build failed in Py3. Other changes ------------- ``` ### 3.0 ``` ================ Features added -------------- 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 ``` ===================== 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 ``` ====================== 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. Patch by Simon Sapin. * 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. Other changes ------------- ``` ### 3.0alpha1 ``` ====================== 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 ``` ================== Features added -------------- Bugs fixed ---------- * Passing long Unicode strings into the ``feed()`` parser interface failed to read the entire string. Other changes -------------- ``` ### 2.3.5 ``` ================== Features added -------------- Bugs fixed ---------- * Crash when merging text nodes in ``element.remove()``. * Crash in sax/target parser when reporting empty doctype. Other changes -------------- ``` ### 2.3.4 ``` ================== Features added -------------- Bugs fixed ---------- * Crash when building an nsmap (Element property) with empty namespace URIs. * Crash due to race condition when errors (or user messages) occur during threaded XSLT processing. * XSLT stylesheet compilation could ignore compilation errors. Other changes -------------- ``` ### 2.3.3 ``` ================== Features added -------------- * ``lxml.html.tostring()`` gained new serialisation options ``with_tail`` and ``doctype``. Bugs fixed ---------- * Fixed a crash when using ``iterparse()`` for HTML parsing and requesting start events. * Fixed parsing of more selectors in cssselect. Whitespace before pseudo-elements and pseudo-classes is significant as it is a descendant combinator. "E :pseudo" should parse the same as "E \*:pseudo", not "E:pseudo". Patch by Simon Sapin. * lxml.html.diff no longer raises an exception when hitting 'img' tags without 'src' attribute. Other changes -------------- ``` ### 2.3.2 ``` ================== Features added -------------- * ``lxml.objectify.deannotate()`` has a new boolean option ``cleanup_namespaces`` to remove the objectify namespace declarations (and generally clean up the namespace declarations) after removing the type annotations. * ``lxml.objectify`` gained its own ``SubElement()`` function as a copy of ``etree.SubElement`` to avoid an otherwise redundant import of ``lxml.etree`` on the user side. Bugs fixed ---------- * Fixed the "descendant" bug in cssselect a second time (after a first fix in lxml 2.3.1). The previous change resulted in a serious performance regression for the XPath based evaluation of the translated expression. Note that this breaks the usage of some of the generated XPath expressions as XSLT location paths that previously worked in 2.3.1. * Fixed parsing of some selectors in cssselect. Whitespace after combinators ">", "+" and "~" is now correctly ignored. Previously it was parsed as a descendant combinator. For example, "div> .foo" was parsed the same as "div>* .foo" instead of "div>.foo". Patch by Simon Sapin. Other changes -------------- ``` ### 2.3.1 ``` ================== Features added -------------- * New option ``kill_tags`` in ``lxml.html.clean`` to remove specific tags and their content (i.e. their whole subtree). * ``pi.get()`` and ``pi.attrib`` on processing instructions to parse pseudo-attributes from the text content of processing instructions. * ``lxml.get_include()`` returns a list of include paths that can be used to compile external C code against lxml.etree. This is specifically required for statically linked lxml builds when code needs to compile against the exact same header file versions as lxml itself. * ``Resolver.resolve_file()`` takes an additional option ``close_file`` that configures if the file(-like) object will be closed after reading or not. By default, the file will be closed, as the user is not expected to keep a reference to it. Bugs fixed ---------- * HTML cleaning didn't remove 'data:' links. * The html5lib parser integration now uses the 'official' implementation in html5lib itself, which makes it work with newer releases of the library. * In ``lxml.sax``, ``endElementNS()`` could incorrectly reject a plain tag name when the corresponding start event inferred the same plain tag name to be in the default namespace. * When an open file-like object is passed into ``parse()`` or ``iterparse()``, the parser will no longer close it after use. This reverts a change in lxml 2.3 where all files would be closed. It is the users responsibility to properly close the file(-like) object, also in error cases. * Assertion error in lxml.html.cleaner when discarding top-level elements. * In lxml.cssselect, use the xpath 'A//B' (short for 'A/descendant-or-self::node()/B') instead of 'A/descendant::B' for the css descendant selector ('A B'). This makes a few edge cases like ``"div *:last-child"`` consistent with the selector behavior in WebKit and Firefox, and makes more css expressions valid location paths (for use in xsl:template match). * In lxml.html, non-selected ``<option>`` tags no longer show up in the collected form values. * Adding/removing ``<option>`` values to/from a multiple select form field properly selects them and unselects them. Other changes -------------- * Static builds can specify the download directory with the ``--download-dir`` option. ``` ### 2.3 ``` ================ Features added -------------- * When looking for children, ``lxml.objectify`` takes '{}tag' as meaning an empty namespace, as opposed to the parent namespace. Bugs fixed ---------- * When finished reading from a file-like object, the parser immediately calls its ``.close()`` method. * When finished parsing, ``iterparse()`` immediately closes the input file. * Work-around for libxml2 bug that can leave the HTML parser in a non-functional state after parsing a severely broken document (fixed in libxml2 2.7.8). * ``marque`` tag in HTML cleanup code is correctly named ``marquee``. Other changes -------------- * Some public functions in the Cython-level C-API have more explicit return types. ``` ### 2.3beta1 ``` ===================== Features added -------------- Bugs fixed ---------- * Crash in newer libxml2 versions when moving elements between documents that had attributes on replaced XInclude nodes. * ``XMLID()`` function was missing the optional ``parser`` and ``base_url`` parameters. * Searching for wildcard tags in ``iterparse()`` was broken in Py3. * ``lxml.html.open_in_browser()`` didn't work in Python 3 due to the use of os.tempnam. It now takes an optional 'encoding' parameter. Other changes -------------- ``` ### 2.3alpha2 ``` ====================== Features added -------------- Bugs fixed ---------- * Crash in XSLT when generating text-only result documents with a stylesheet created in a different thread. Other changes -------------- * ``repr()`` of Element objects shows the hex ID with leading 0x (following ElementTree 1.3). ``` ### 2.3alpha1 ``` ====================== Features added -------------- * Keyword argument ``namespaces`` in ``lxml.cssselect.CSSSelector()`` to pass a prefix-to-namespace mapping for the selector. * New function ``lxml.etree.register_namespace(prefix, uri)`` that globally registers a namespace prefix for a namespace that newly created Elements in that namespace will use automatically. Follows ElementTree 1.3. * Support 'unicode' string name as encoding parameter in ``tostring()``, following ElementTree 1.3. * Support 'c14n' serialisation method in ``ElementTree.write()`` and ``tostring()``, following ElementTree 1.3. * The ElementPath expression syntax (``el.find*()``) was extended to match the upcoming ElementTree 1.3 that will ship in the standard library of Python 3.2/2.7. This includes extended support for predicates as well as namespace prefixes (as known from XPath). * During regular XPath evaluation, various ESXLT functions are available within their namespace when using libxslt 1.1.26 or later. * Support passing a readily configured logger instance into ``PyErrorLog``, instead of a logger name. * On serialisation, the new ``doctype`` parameter can be used to override the DOCTYPE (internal subset) of the document. * New parameter ``output_parent`` to ``XSLTExtension.apply_templates()`` to append the resulting content directly to an output element. * ``XSLTExtension.process_children()`` to process the content of the XSLT extension element itself. * ISO-Schematron support based on the de-facto Schematron reference 'skeleton implementation'. * XSLT objects now take XPath object as ``__call__`` stylesheet parameters. * Enable path caching in ElementPath (``el.find*()``) to avoid parsing overhead. * Setting the value of a namespaced attribute always uses a prefixed namespace instead of the default namespace even if both declare the same namespace URI. This avoids serialisation problems when an attribute from a default namespace is set on an element from a different namespace. * XSLT extension elements: support for XSLT context nodes other than elements: document root, comments, processing instructions. * Support for strings (in addition to Elements) in node-sets returned by extension functions. * Forms that lack an ``action`` attribute default to the base URL of the document on submit. * XPath attribute result strings have an ``attrname`` property. * Namespace URIs get validated against RFC 3986 at the API level (required by the XML namespace specification). * Target parsers show their target object in the ``.target`` property (compatible with ElementTree). Bugs fixed ---------- * API is hardened against invalid proxy instances to prevent crashes due to incorrectly instantiated Element instances. * Prevent crash when instantiating ``CommentBase`` and friends. * Export ElementTree compatible XML parser class as ``XMLTreeBuilder``, as it is called in ET 1.2. * ObjectifiedDataElements in lxml.objectify were not hashable. They now use the hash value of the underlying Python value (string, number, etc.) to which they compare equal. * Parsing broken fragments in lxml.html could fail if the fragment contained an orphaned closing '</div>' tag. * Using XSLT extension elements around the root of the output document crashed. * ``lxml.cssselect`` did not distinguish between ``x[attr="val"]`` and ``x [attr="val"]`` (with a space). The latter now matches the attribute independent of the element. * Rewriting multiple links inside of HTML text content could end up replacing unrelated content as replacements could impact the reported position of subsequent matches. Modifications are now simplified by letting the ``iterlinks()`` generator in ``lxml.html`` return links in reversed order if they appear inside the same text node. Thus, replacements and link-internal modifications no longer change the position of links reported afterwards. * The ``.value`` attribute of ``textarea`` elements in lxml.html did not represent the complete raw value (including child tags etc.). It now serialises the complete content on read and replaces the complete content by a string on write. * Target parser didn't call ``.close()`` on the target object if parsing failed. Now it is guaranteed that ``.close()`` will be called after parsing, regardless of the outcome. Other changes ------------- * Official support for Python 3.1.2 and later. * Static MS Windows builds can now download their dependencies themselves. * ``Element.attrib`` no longer uses a cyclic reference back to its Element object. It therefore no longer requires the garbage collector to clean up. * Static builds include libiconv, in addition to libxml2 and libxslt. ``` ### 2.2.8 ``` ================== Bugs fixed ---------- * Crash in newer libxml2 versions when moving elements between documents that had attributes on replaced XInclude nodes. * Import fix for urljoin in Python 3.1+. ``` ### 2.2.7 ``` ================== Bugs fixed ---------- * Crash in XSLT when generating text-only result documents with a stylesheet created in a different thread. ``` ### 2.2.6 ``` ================== Bugs fixed ---------- * Fixed several Python 3 regressions by building with Cython 0.11.3. ``` ### 2.2.5 ``` ================== Features added -------------- * Support for running XSLT extension elements on the input root node (e.g. in a template matching on "/"). Bugs fixed ---------- * Crash in XPath evaluation when reading smart strings from a document other than the original context document. * Support recent versions of html5lib by not requiring its ``XHTMLParser`` in ``htmlparser.py`` anymore. * Manually instantiating the custom element classes in ``lxml.objectify`` could crash. * Invalid XML text characters were not rejected by the API when they appeared in unicode strings directly after non-ASCII characters. * lxml.html.open_http_urllib() did not work in Python 3. * The functions ``strip_tags()`` and ``strip_elements()`` in ``lxml.etree`` did not remove all occurrences of a tag in all cases. * Crash in XSLT extension elements when the XSLT context node is not an element. ``` ### 2.2.4 ``` ================== Bugs fixed ---------- * Static build of libxml2/libxslt was broken. ``` ### 2.2.3 ``` ================== Features added -------------- Bugs fixed ---------- * The ``resolve_entities`` option did not work in the incremental feed parser. * Looking up and deleting attributes without a namespace could hit a namespaced attribute of the same name instead. * Late errors during calls to ``SubElement()`` (e.g. attribute related ones) could leave a partially initialised element in the tree. * Modifying trees that contain parsed entity references could result in an infinite loop. * ObjectifiedElement.__setattr__ created an empty-string child element when the attribute value was rejected as a non-unicode/non-ascii string * Syntax errors in ``lxml.cssselect`` could result in misleading error messages. * Invalid syntax in CSS expressions could lead to an infinite loop in the parser of ``lxml.cssselect``. * CSS special character escapes were not properly handled in ``lxml.cssselect``. * CSS Unicode escapes were not properly decoded in ``lxml.cssselect``. * Select options in HTML forms that had no explicit ``value`` attribute were not handled correctly. The HTML standard dictates that their value is defined by their text content. This is now supported by lxml.html. * XPath raised a TypeError when finding CDATA sections. This is now fully supported. * Calling ``help(lxml.objectify)`` didn't work at the prompt. * The ``ElementMaker`` in lxml.objectify no longer defines the default namespaces when annotation is disabled. * Feed parser failed to honour the 'recover' option on parse errors. * Diverting the error logging to Python's logging system was broken. Other changes ------------- ``` ### 2.2.2 ``` ================== Features added -------------- * New helper functions ``strip_attributes()``, ``strip_elements()``, ``strip_tags()`` in lxml.etree to remove attributes/subtrees/tags from a subtree. Bugs fixed ---------- * Namespace cleanup on subtree insertions could result in missing namespace declarations (and potentially crashes) if the element defining a namespace was deleted and the namespace was not used by the top element of the inserted subtree but only in deeper subtrees. * Raising an exception from a parser target callback didn't always terminate the parser. * Only {true, false, 1, 0} are accepted as the lexical representation for BoolElement ({True, False, T, F, t, f} not any more), restoring lxml <= 2.0 behaviour. Other changes ------------- ``` ### 2.2.1 ``` ================== Features added -------------- * Injecting default attributes into a document during XML Schema validation (also at parse time). * Pass ``huge_tree`` parser option to disable parser security restrictions imposed by libxml2 2.7. Bugs fixed ---------- * The script for statically building libxml2 and libxslt didn't work in Py3. * ``XMLSchema()`` also passes invalid schema documents on to libxml2 for parsing (which could lead to a crash before release 2.6.24). Other changes ------------- ``` ### 2.2 ``` ================ Features added -------------- * Support for ``standalone`` flag in XML declaration through ``tree.docinfo.standalone`` and by passing ``standalone=True/False`` on serialisation. Bugs fixed ---------- * Crash when parsing an XML Schema with external imports from a filename. ``` ### 2.2beta4 ``` ===================== Features added -------------- * Support strings and instantiable Element classes as child arguments to the constructor of custom Element classes. * GZip compression support for serialisation to files and file-like objects. Bugs fixed ---------- * Deep-copying an ElementTree copied neither its sibling PIs and comments nor its internal/external DTD subsets. * Soupparser failed on broken attributes without values. * Crash in XSLT when overwriting an already defined attribute using ``xsl:attribute``. * Crash bug in exception handling code under Python 3. This was due to a problem in Cython, not lxml itself. * ``lxml.html.FormElement._name()`` failed for non top-level forms. * ``TAG`` special attribute in constructor of custom Element classes was evaluated incorrectly. Other changes ------------- * Official support for Python 3.0.1. * ``Element.findtext()`` now returns an empty string instead of None for Elements without text content. ``` ### 2.2beta3 ``` ===================== Features added -------------- * ``XSLT.strparam()`` class method to wrap quoted string parameters that require escaping. Bugs fixed ---------- * Memory leak in XPath evaluators. * Crash when parsing indented XML in one thread and merging it with other documents parsed in another thread. * Setting the ``base`` attribute in ``lxml.objectify`` from a unicode string failed. * Fixes following changes in Python 3.0.1. * Minor fixes for Python 3. Other changes ------------- * The global error log (which is copied into the exception log) is now local to a thread, which fixes some race conditions. * More robust error handling on serialisation. ``` ### 2.2beta2 ``` ===================== Bugs fixed ---------- * Potential memory leak on exception handling. This was due to a problem in Cython, not lxml itself. * ``iter_links`` (and related link-rewriting functions) in ``lxml.html`` would interpret CSS like ``url("link")`` incorrectly (treating the quotation marks as part of the link). * Failing import on systems that have an ``io`` module. ``` ### 2.2beta1 ``` ===================== Features added -------------- * Allow ``lxml.html.diff.htmldiff`` to accept Element objects, not just HTML strings. Bugs fixed ---------- * Crash when using an XPath evaluator in multiple threads. * Fixed missing whitespace before ``Link:...`` in ``lxml.html.diff``. Other changes ------------- * Export ``lxml.html.parse``. ``` ### 2.2alpha1 ``` ====================== Features added -------------- * Support for XSLT result tree fragments in XPath/XSLT extension functions. * QName objects have new properties ``namespace`` and ``localname``. * New options for exclusive C14N and C14N without comments. * Instantiating a custom Element classes creates a new Element. Bugs fixed ---------- * XSLT didn't inherit the parse options of the input document. * 0-bytes could slip through the API when used inside of Unicode strings. * With ``lxml.html.clean.autolink``, links with balanced parenthesis, that end in a parenthesis, will be linked in their entirety (typical with Wikipedia links). Other changes ------------- ``` ### 2.1.5 ``` ================== Bugs fixed ---------- * Potential memory leak on exception handling. This was due to a problem in Cython, not lxml itself. * Failing import on systems that have an ``io`` module. ``` ### 2.1.4 ``` ================== Bugs fixed ---------- * Crash when using an XPath evaluator in multiple threads. ``` ### 2.1.3 ``` ================== Features added -------------- Bugs fixed ---------- * Ref-count leaks when lxml enters a try-except statement while an outside exception lives in sys.exc_*(). This was due to a problem in Cython, not lxml itself. * Parser Unicode decoding errors could get swallowed by other exceptions. * Name/import errors in some Python modules. * Internal DTD subsets that did not specify a system or public ID were not serialised and did not appear in the docinfo property of ElementTrees. * Fix a pre-Py3k warning when parsing from a gzip file in Py2.6. * Test suite fixes for libxml2 2.7. * Resolver.resolve_string() did not work for non-ASCII byte strings. * Resolver.resolve_file() was broken. * Overriding the parser encoding didn't work for many encodings. Other changes ------------- ``` ### 2.1.2 ``` ================== Features added -------------- * lxml.etree now tries to find the absolute path name of files when parsing from a file-like object. This helps custom resolvers when resolving relative URLs, as lixbml2 can prepend them with the path of the source document. Bugs fixed ---------- * Memory problem when passing documents between threads. * Target parser did not honour the ``recover`` option and raised an exception instead of calling ``.close()`` on the target. Other changes ------------- ``` ### 2.1.1 ``` ================== Features added -------------- Bugs fixed ---------- * Crash when parsing XSLT stylesheets in a thread and using them in another. * Encoding problem when including text with ElementInclude under Python 3. Other changes ------------- ``` ### 2.1 ``` ================ Features added -------------- * Smart strings can be switched off in XPath (``smart_strings`` keyword option). * ``lxml.html.rewrite_links()`` strips links to work around documents with whitespace in URL attributes. Bugs fixed ---------- * Custom resolvers were not used for XMLSchema includes/imports and XInclude processing. * CSS selector parser dropped remaining expression after a function with parameters. Other changes ------------- * ``objectify.enableRecursiveStr()`` was removed, use ``objectify.enable_recursive_str()`` instead * Speed-up when running XSLTs on documents from other threads ``` ### 2.1beta3 ``` ===================== Features added -------------- * Major overhaul of ``tools/xpathgrep.py`` script. * Pickling ``ElementTree`` objects in lxml.objectify. * Support for parsing from file-like objects that return unicode strings. * New function ``etree.cleanup_namespaces(el)`` that removes unused namespace declarations from a (sub)tree (experimental). * XSLT results support the buffer protocol in Python 3. * Polymorphic functions in ``lxml.html`` that accept either a tree or a parsable string will return either a UTF-8 encoded byte string, a unicode string or a tree, based on the type of the input. Previously, the result was always a byte string or a tree. * Support for Python 2.6 and 3.0 beta. * File name handling now uses a heuristic to convert between byte strings (usually filenames) and unicode strings (usually URLs). * Parsing from a plain file object frees the GIL under Python 2.x. * Running ``iterparse()`` on a plain file (or filename) frees the GIL on reading under Python 2.x. * Conversion functions ``html_to_xhtml()`` and ``xhtml_to_html()`` in lxml.html (experimental). * Most features in lxml.html work for XHTML namespaced tag names (experimental). Bugs fixed ---------- * ``ElementTree.parse()`` didn't handle target parser result. * Crash in Element class lookup classes when the __init__() method of the super class is not called from Python subclasses. * A number of problems related to unicode/byte string conversion of filenames and error messages were fixed. * Building on MacOS-X now passes the "flat_namespace" option to the C compiler, which reportedly prevents build quirks and
