[Bug 419812] Re: sync request (unstable -> main)

[Matthias Klose]

hmm, missed the freeze date by eight hours ... I won't fight for it.

Upstream changes are:


2.2.2 (2009-06-21)
==================

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 (2009-06-02)
==================
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 (2009-03-21)
================

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 (2009-02-27)
=====================

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 (2009-02-17)
=====================

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 (2009-01-25)
=====================

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.
