lxml changelog
==============
3.6.4 (2016-08-20)
==================
* GH#204, LP#1614693: build fix for MacOS-X.
3.6.3 (2016-08-18)
==================
* LP#1614603: change linker flags to build multi-linux wheels
3.6.2 (2016-08-18)
==================
* LP#1614603: release without source changes to provide cleanly built Linux wheels
3.6.1 (2016-07-24)
==================
Features added
--------------
* GH#180: Separate option ``inline_style`` for Cleaner that only removes ``style``
attributes instead of all styles. Patch by Christian Pedersen.
* GH#196: Windows build support for Python 3.5. Contribution by Maximilian Hils.
Bugs fixed
----------
* GH#199: Exclude ``file`` fields from ``FormElement.form_values`` (as browsers do).
Patch by Tomas Divis.
* GH#198, LP#1568167: Try to provide base URL from ``Resolver.resolve_string()``.
Patch by Michael van Tellingen.
* GH#191: More accurate float serialisation in ``objectify.FloatElement``.
Patch by Holger Joukl.
* LP#1551797: Repair XSLT error logging. Patch by Marcus Brinkmann.
3.6.0 (2016-03-17)
==================
Features added
--------------
* GH#187: Now supports (only) version 5.x and later of PyPy.
Patch by Armin Rigo.
* GH#181: Direct support for ``.rnc`` files in `RelaxNG()` if ``rnc2rng``
is installed. Patch by Dirkjan Ochtman.
Bugs fixed
----------
* GH#189: Static builds honour FTP proxy configurations when downloading
the external libs. Patch by Youhei Sakurai.
* GH#186: Soupparser failed to process entities in Python 3.x.
Patch by Duncan Morris.
* GH#185: Rare encoding related ``TypeError`` on import was fixed.
Patch by Petr Demin.
3.5.0 (2015-11-13)
==================
Bugs fixed
----------
* Unicode string results failed XPath queries in PyPy.
* LP#1497051: HTML target parser failed to terminate on exceptions
and continued parsing instead.
* Deprecated API usage in doctestcompare.
3.5.0b1 (2015-09-18)
====================
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.
* LP#1490451: ``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.
* LP#1243600: Elements in ``lxml.html`` gained a ``classes`` property
that provides a set-like interface to the ``class`` attribute.
Original patch by masklinn.
* LP#1341964: The soupparser now handles DOCTYPE declarations, comments
and processing instructions outside of the root element.
Patch by Olli Pottonen.
* LP#1421512: 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.
* LP#1442427: 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.
* GH#162: Image data in HTML ``data`` URLs is considered safe and
no longer removed by ``lxml.html.clean`` JavaScript cleaner.
* GH#166: Static build could link libraries in wrong order.
* GH#172: Rely a bit more on libxml2 for encoding detection rather than
rolling our own in some cases. Patch by Olli Pottonen.
* GH#159: Validity checks for names and string content were tightened
to detect the use of illegal characters early. Patch by Olli Pottonen.
* LP#1421921: Comments/PIs before the DOCTYPE declaration were not
serialised. Patch by Olli Pottonen.
* LP#659367: Some HTML DOCTYPE declarations were not serialised.
Patch by Olli Pottonen.
* LP#1238503: 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 (2015-04-25)
==================
Bugs fixed
----------
* An ElementTree compatibility test added in lxml 3.4.3 that failed in
Python 3.4+ was removed again.
3.4.3 (2015-04-15)
==================
Bugs fixed
----------
* Expression cache in ElementPath was ignored. Fix by Changaco.
* LP#1426868: Passing a default namespace and a prefixed namespace mapping
as nsmap into ``xmlfile.element()`` raised a ``TypeError``.
* LP#1421927: DOCTYPE system URLs were incorrectly quoted when containing
double quotes. Patch by Olli Pottonen.
* LP#1419354: meta-redirect URLs were incorrectly processed by
``iterlinks()`` if preceded by whitespace.
3.4.2 (2015-02-07)
==================
Bugs fixed
----------
* LP#1415907: Crash when creating an XMLSchema from a non-root element
of an XML document.
* LP#1369362: 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 (2014-11-20)
==================
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 (2014-09-10)
==================
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
-------------
* LP#400588: 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 (2014-08-28)
==================
Bugs fixed
----------
* Prevent tree cycle creation when adding Elements as siblings.
* LP#1361948: crash when deallocating Element siblings without parent.
* LP#1354652: crash when traversing internally loaded documents in XSLT
extension functions.
3.3.5 (2014-04-18)
==================
Bugs fixed
----------
* HTML cleaning could fail to strip javascript links that mix control
characters into the link scheme.
3.3.4 (2014-04-03)
==================
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 (2014-03-04)
==================
Bugs fixed
----------
* LP#1287118: 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 (2014-02-26)
==================
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.
* 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 non-portable temp
file usage. Initial patch by Gabi Davar.
* LP#910014: duplicate IDs in a document were not reported by DTD validation.
* LP#1185332: ``tostring(method="html")`` did not use HTML serialisation
semantics for trailing tail text. Initial patch by Sylvain Viollon.
* LP#1281139: ``.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 (2014-02-12)
==================
Features added
--------------
Bugs fixed
----------
* LP#1014290: HTML documents parsed with ``parser.feed()`` failed to find
elements during tag iteration.
* LP#1273709: Building in PyPy failed due to missing support for
``PyUnicode_Compare()`` and ``PyByteArray_*()`` in PyPy's C-API.
* LP#1274413: Compilation in MSVC failed due to missing "stdint.h" standard
header file.
* LP#1274118: iterparse() failed to parse BOM prefixed files.
Other changes
-------------
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.
3.2.5 (2014-01-02)
==================
Features added
--------------
Bugs fixed
----------
* Crash in xmlfile() when closing open elements out of order in an error case.
* Crash in target parsing with attributes.
* LP#1255132: crash when trying to run validation over non-Element (e.g.
comment or PI).
Other changes
-------------
3.2.4 (2013-11-07)
==================
Features added
--------------
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.
Other changes
-------------
3.2.3 (2013-07-28)
==================
Bugs fixed
----------
* Fix support for Python 2.4 which was lost in 3.2.2.
3.2.2 (2013-07-28)
==================
Features added
--------------
Bugs fixed
----------
* LP#1185701: 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 (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.
Other changes
-------------
3.2.0 (2013-04-28)
==================
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.
Other changes
-------------
3.1.2 (2013-04-12)
==================
Features added
--------------
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()``.
Other changes
-------------
3.1.1 (2013-03-29)
==================
Features added
--------------
Bugs fixed
----------
* LP#1160386: 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 (2013-02-10)
==================
Features added
--------------
* GH#89: lxml.html.clean allows overriding the set of attributes that it
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.
Other changes
-------------
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.
* GH#85: Deprecation warnings were fixed for Python 3.x.
* GH#33: lxml.html.fromstring() failed to accept bytes input in Py3.
* LP#1080792: 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.
* LP#1075622: lxml.builder is faster for adding text to elements with
many children. Patch by Anders Hammarquist.
3.0.2 (2012-12-14)
==================
Features added
--------------
Bugs fixed
----------
* Fix crash during interpreter shutdown by switching to Cython 0.17.3 for building.
Other changes
-------------
3.0.1 (2012-10-14)
==================
Features added
--------------
Bugs fixed
----------
* LP#1065924: Element proxies could disappear during garbage collection
in PyPy without proper cleanup.
* GH#71: Failure to work with libxml2 2.6.x.
* LP#1065139: static MacOS-X build failed in Py3.
Other changes
-------------
3.0 (2012-10-08)
================
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 (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. 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 (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:
