lxml 3.4.1 released

Hi all, I just released an "incremental improvements" version of lxml, 3.4.1, with only one real addition: an "htmlfile" class that accompanies the existing "xmlfile" incremental serialisation class. Note that the 3.4 release series no longer supports Python versions before Py2.6 and Py3.2. Support for very old versions of libxml2 and libxslt (<=2008) was also removed. The documentation is here: http://lxml.de/ Download: http://lxml.de/files/lxml-3.4.1.tgz Signature: http://lxml.de/files/lxml-3.4.1.tgz.asc Changelog: http://lxml.de/3.4/changes-3.4.1.html Github: https://github.com/lxml/lxml/commit/55b7af55eeb50abab9ca6d251d6137607849d6a1 This release was built using Cython 0.21.1, but should also build fine with 0.20.x. If you are interested in commercial support or customisations for the lxml package, please contact me directly. Have fun, Stefan 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.

static compilation of lxml 3.4.0
by Isaac Councill 17 Nov '14

Hi, FYI I ran into a problem over the weekend with creating a static lxml wheel on centos 6.5. There were several missing CFLAGS (generally known according to a google search), and one step I didn't see involving a missing -liconv flag during the linking of etree.so In case it's useful, here are the steps I followed to create a working static lxml wheel: CFLAGS="-lgcrypt -fPIC -lrt -ldl -lgpg-error -Wl,--no-as-needed" \ /usr/python2.7/bin/python2.7 setup.py bdist_wheel --static-deps That got me most of the way except I got a runtime error that symbol libiconv was undefined. So I manually re-linked etree.so as follows: gcc -pthread -shared -lgcrypt -fPIC -lrt -ldl -lgpg-error -Wl,--no-as-needed \ build/temp.linux-x86_64-2.7/src/lxml/lxml.etree.o \ /home/isaac/lxml-3.4.0/build/tmp/libxml2/lib/libxslt.a \ /home/isaac/lxml-3.4.0/build/tmp/libxml2/lib/libiconv.a \ /home/isaac/lxml-3.4.0/build/tmp/libxml2/lib/libexslt.a \ /home/isaac/lxml-3.4.0/build/tmp/libxml2/lib/libxml2.a \ -L/home/isaac/lxml-3.4.0/build/tmp/libxml2/lib -L/usr/python2.7/lib64 \ -lz -lm -liconv -lpython2.7 -o build/lib.linux-x86_64-2.7/lxml/etree.so The only difference from the automated build step is the inclusion of "-liconv". Then I re-reran the first command, which picked up the re-linked etree.so and created a working static lxml wheel. I didn't have time to do it right and send a diff, so just passing this on in case it helps someone. -Isaac

Hi, I was wondering why the choice was made to only diff html fragments. Why not entire documents? Thanks

Crash on MacOS-X when importing tkinter
by Stefan Behnel 01 Nov '14

Hi, I got a crash report when importing tkinter and lxml together under MacOS-X. https://bugs.launchpad.net/lxml/+bug/1384102 Could other Apple users please try the following couple of commands and report if they trigger a crash for them or not? """ import tkinter from lxml import etree print("%-20s: %s" % ('Python', sys.version_info)) print("%-20s: %s" % ('lxml.etree', etree.LXML_VERSION)) print("%-20s: %s" % ('libxml used', etree.LIBXML_VERSION)) print("%-20s: %s" % ('libxml compiled', etree.LIBXML_COMPILED_VERSION)) print("%-20s: %s" % ('libxslt used', etree.LIBXSLT_VERSION)) print("%-20s: %s" % ('libxslt compiled', etree.LIBXSLT_COMPILED_VERSION)) root = etree.Element('test') xml = etree.tostring(root) # <- crashing here """ Please report the library versions that you are using (printed above) and whether it's a static lxml build or links dynamically against libxml2. If someone has gdb available and can provide further information about the spot in libxml2 where this crashes, I'd be happy to hear them. Thanks! Stefan
