User:Toshio/Remove PyXML: Difference between revisions

Revision as of 06:51, 25 July 2012

PyXML has been dead upstream for quite a while. The current maintainer (rrakus) asked about removing it in February. The python stdlib has the main pieces of PyXML included as the xml module.

The Python stdlib in python2.x also has the dubious behaviour of importing PyXML if it is installed and replacing its own code with PyXML's. In some cases, this leads to bugs as the old PyXML code does not cope with some usages that the version in the stdlib does.

Deps

Dep analysis

In Progress

Easy Fixes

python-nova looks false. Only uses minidom and parsers.expat which are in the stdlib. Nothing in the documentation mentions pyxml
- https://bugzilla.redhat.com/show_bug.cgi?id=842866
salt - Looks false. salt uses xml.dom.minidom which is in the python stdlib.
- https://bugzilla.redhat.com/show_bug.cgi?id=842850
xen looks like an old dep. Upstream has actively ported from PyXML to lxml in the past.
- I found one instance where PyXML was still required for PrettyPrint().
- Submitted bugzilla https://bugzilla.redhat.com/show_bug.cgi?id=842843 with the following:
  - Remove PyXML Dep
  - Add python-lxml dep
  - Patch to use doc.toprettyxml() instead of pyxml's PrettyPrint(doc)
grc
- Appears to use xml.dom.ext in one place to prettyprint and save to a file
  - Could generate a patch to have this use stdlib
- Looks like this package should be retired: https://bugzilla.redhat.com/show_bug.cgi?id=652370
openerp
- Appears not to need pyxml. The code uses lxml and minidom extensively which is in pyhton-lxml and the stdlib.
- See some upstream bugs about actively porting away from PyXML between 5.0.x and 6.x
- https://bugzilla.redhat.com/show_bug.cgi?id=842882
synce-sync-engine
- Looks like the package was ported to libxml2-pyhon at some point in the past. Should be able to just drop the dep
- https://bugzilla.redhat.com/show_bug.cgi?id=842887

Require coding

bkchem Looks like a single plugin currently needs PyXML (for xpath).
- Reviewing the code, I find that it's using xml.minidom, xml.sax in many places. These are implemented in the python stdlib xml module. The bkchem progress.log talks about removing an unnecessary dep on pyxml so it seems to agree that for the main library, pyxml is optional.
- bkchem/plugins/gtml.py ("GTML import-export plugin") has an import xml.xpath. This submodule is only in PyXML so we'll have to port it to some other xml library or not ship it. It looks fairly straightforward to port. In each case, it's using xpath.Evaluate to retrieve a list of nodes that match an expression and then iterating over them.
comoonics-base-py uses xml.dom.ext xml.parsers.xmlproc xml.dom.Element xml.xpath -- Lots of code that will need changing
comoonics-cdsl-py uses xml.dom.ext xml.xpath -- Lots of code will need changing
comoonics-cluster-py uses xml.dom.ext xml.xpath -- Lots of code will need changing
libopensync-plugin-google-calendar
- In one function, it uses xml.xpath the usage is to "Return value of first element matching xpath expression" ./src/google-cal-helper.py
openxcap
- Requires sax.handler.feature_namespace_prefixes in sax.make_parser() This is available in PyXML but not stdlib.
python-ZSI v2.0 uses PyXML. It looks like much (but not all) of the code has fallbacks to use locally maintained code if PyXML is not installed. python-ZSI-2.1a1 does not use PyXML. It looks like no one involved in PyXML is interested in making releases but we could package either the 2.1a1 or a snapshot to get rid of the PyXML dependency and pick up accumulated bugfixes. Debian and Gentoo are both shipping packages based on 2.1a1.
spacewalk-backend-tools -- uses PyXML in some test cases. Possible that the main code uses non-stdlib features of standard modules like dom.minidom.
- ./satellite_tools/test/testxmlparser.py from xml.unicode.utf8_iso import utf8_to_code
- ./satellite_tools/test/testxmlwriter.py import xml.sax.writer
subscription-manager
- ./src/subscription_manager/managerlib.py xml.utils.iso860 -- used to parse a date?
- ./test/test_managerlib.py used to test parsing the date in managerlib
- Should be able to port to python-dateutil http://wiki.python.org/moin/WorkingWithTime

Fixed

SOAPpy looks like PyXML is unneeded. https://sourceforge.net/tracker/?func=detail&aid=3547666&group_id=26590&atid=387667
- SOAPpy has a new upstream: http://pypi.python.org/pypi/SOAPpy/ https://github.com/kiorky/SOAPpy and PyXML is not listed as a dependency.
- Removed the dep in F18 and see if anything breaks
- Update in rawhide to a new version of SOAPpy once F18 branches: https://bugzilla.redhat.com/show_bug.cgi?id=842786
eric -- Looks like eric will fallback to a non-validating XML parser from the stdlib if PyXML is not installed. (Note that eric also requests a bugfix of PyXML which we should but aren't applying as a patch to our PyXML package https://bugzilla.redhat.com/show_bug.cgi?id=767737 ).
- Updated in F18-Rawhide. Will close the bug against PyXML if this works out.
fedora-business-cards fixed
heartbeat -- retired in F18
inksmoto looks false: Upstream seems to have ported from PyXML to python-lxml in the past. Code review supports that.
- https://bugzilla.redhat.com/show_bug.cgi?id=842853

Alternatives

Instead of removing PyXML, we can stop the stdlib from making use of PyXML if it is installed. This will solve the problem where other packages use PyXML when they don't desire to simply because PyXML is installed on their system.

Packages which really do need to use PyXML will need to be patches to do something like:

-from xml.ext import NameSpace
+from _xmlplus.ext import NameSpace

Request to modify the Python stdlib in that manner is here: https://bugzilla.redhat.com/show_bug.cgi?id=795875
