- ==================

-

- ----------

-

- * The properties ``resolvers`` and ``version``, as well as the methods

-   ``set_element_class_lookup()`` and ``makeelement()``, were lost from

-   ``iterparse`` objects.

-

- * LP#1222132: instances of ``XMLSchema``, ``Schematron`` and ``RelaxNG``

-   did not clear their local ``error_log`` before running a validation.

-

- * LP#1238500: lxml.doctestcompare mixed up "expected" and "actual" in

-   attribute values.

-

- * Some file I/O tests were failing in MS-Windows due to incorrect temp

-   file usage.  Initial patch by Gabi Davar.

-

- * LP#910014: duplicate IDs in a document were not reported by DTD

-

- * LP#1281139: ``.attrib`` value of Comments lost its mutation methods

* Fri Feb 28 2014 Jeffrey Ollie <jeff@ocjtech.us> - 3.3.2-1

- 3.3.1 (2014-02-12)

* Mon Jan 27 2014 Jeffrey Ollie <jeff@ocjtech.us> - 3.3.0-1

- 3.3.0 (2014-01-26)

- ==================

-

- Features added

- --------------

-

- Bugs fixed

- ----------

-

- * The heuristic that distinguishes file paths from URLs was tightened

-   to produce less false negatives.

-

- Other changes

- -------------

-

-

- 3.3.0beta5 (2014-01-18)

- =======================

-

- 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 (2014-01-12)

- =======================

-

- 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``.

-

- * LP#1266171: 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 (2014-01-02)

- =======================

-

- 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 (2013-12-20)

- =======================

-

- 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 (2013-12-12)

- =======================

-

- 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

- ----------

-

- * LP#1255132: 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.

-

- * LP#1228881: ``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.

-

- * LP#1206077: 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.

* Mon Nov 11 2013 Jeffrey Ollie <jeff@ocjtech.us> - 3.2.4-1

- 3.2.4 (2013-11-07)

- ==================

-

- Bugs fixed

- ----------

-

- * Memory leak when creating an XPath evaluator in a thread.

-

- * LP#1228881: ``repr(XSLTAccessControl)`` failed in Python 3.

-

- * Raise ``ValueError`` when trying to append an Element to itself or

-   to one of its own descendants.

-

- * LP#1206077: htmldiff discarded whitespace from the output.

-

- * Compressed plain-text serialisation to file-like objects was broken.

* Wed Sep 18 2013 Jeffrey Ollie <jeff@ocjtech.us> - 3.2.3-2

- Add requirement for on python-cssselect for the python2 version

* Sun Jul 28 2013 Jeffrey Ollie <jeff@ocjtech.us> - 3.2.3-1

- and here's a version 3.2.3. The last release accidentally lost the ability

- to work on Python 2.4. There are no other changes over 3.2.2.

-

-

- * 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.

* Sun May 12 2013 Jeffrey Ollie <jeff@ocjtech.us> - 3.2.1-1

- 3.2.1 (2013-05-11)

- ==================

-

- 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.

* Fri May 10 2013 Jeffrey Ollie <jeff@ocjtech.us> - 3.2.0-1

- ==================

-

- Features added

- --------------

-

- Bugs fixed

- ----------

-

- * LP#690319: Leading whitespace could change the behaviour of the string

-   parsing functions in ``lxml.html``.

-

- * LP#599318: 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.

-

- * LP#712941: I/O errors while trying to access files with paths that

-   contain non-ASCII characters could raise ``UnicodeDecodeError`` instead

-   of properly reporting the ``IOError``.

-

- * LP#673205: Parsing from in-memory strings disabled network access in the

-   default parser and made subsequent attempts to parse from a URL fail.

-

- * LP#971754: lxml.html.clean appends 'nofollow' to 'rel' attributes instead

-   of overwriting the current value.

-

- * LP#715687: lxml.html.clean no longer discards scripts that are explicitly

-   allowed by the user provided whitelist.  Patch by Christine Koppelt.

-

- 3.1.2 (2013-04-12)

- ==================

-

- Bugs fixed

- ----------

-

- * LP#1136509: 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.

-

- * LP#1123074: Fix serialisation error in XSLT output when converting

-   the result tree to a Unicode string.

-

- * GH#105: Replace illegal usage of ``xmlBufLength()`` in libxml2 2.9.0

-   by properly exported API function ``xmlBufUse()``.

- ==================

-

-   considers 'safe'.  Patch by Francis Devereux.

-

- Bugs fixed

- ----------

-

- * LP#1104370: ``copy.copy(el.attrib)`` raised an exception.  It now returns

-   a copy of the attributes as a plain Python dict.

-

- * GH#95: 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.

-

- * LP#1092521, GH#91: Fix undefined C symbol in Python runtimes compiled

-   without threading support.  Patch by Ulrich Seidl.

- =====================

-

-

- * 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.

-

- * GH#85: Deprecation warnings were fixed for Python 3.x.

-

- * GH#33: lxml.html.fromstring() failed to accept bytes input in Py3.

- Bugs fixed

-   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".
