I couldn't reopen bug 233973 so i'm opening new. Repoman doesn't work again when python:2.6 is compilled with "-xml" or pyxml isn't installed on system. # repoman Traceback (most recent call last): File "/usr/bin/repoman", line 60, in <module> from repoman import utilities File "/usr/lib/portage/pym/repoman/utilities.py", line 32, in <module> from xml.parsers.expat import ExpatError File "/usr/lib/python2.6/xml/parsers/expat.py", line 4, in <module> from pyexpat import * ImportError: No module named pyexpat Reproducible: Always Steps to Reproduce: 1.USE="-xml" emerge -1 python:2.6 2.emerge -C pyxml 3.emerge gentoolkit && repoman #

Looks like you're using portage the wrong way. If you switched useflags by USE, not package.use, settings were not preserved and without '-N' portage doesn't check useflag changes. Well, anyway, all the versions in portage have python[xml] dep.
(In reply to comment #1) > Looks like you're using portage the wrong way. > If you switched useflags by USE, not package.use, > settings were not preserved and without '-N' > portage doesn't check useflag changes. It was way to reproduce error. I've got USE "-xml" in make.conf > Well, anyway, all the versions in portage have python[xml] dep. I can see two problems: wrong dependency in gentoolkit [1] (it still use python:2.6 not 3.1) so DEPEND should look like this: dev-lang/python:2.6[xml]. And second, should portage check all slotted version of python for support of xml? [1] - i've got python 2.6 compiled without xml and python:3.1 with xml support.
What's your active python version ? ...2.6, right ?
*** Bug 304189 has been marked as a duplicate of this bug. ***
Yes, my active version is python-2.6 .
eselect is a system, not portage module. portage in deps calculation does not (and probably can't) take various eselect settings, it only verifies, that there's an installed version, that matches requirements. There is one: python-3.1.1-r1[xml]. I think CANTFIX is the resolution here.
Rafał, currently gentoolkit partially suports python3. Repoman can work with python3 , equery probably has workarround to always run with python2 (even when eselect python is set to python3) . Glsa-check, revdep, epkginfo.. the same, they force to use python2. : # eselect python list Available Python interpreters: [1] python2.6 [2] python3.1 * # epkginfo -d gzip Traceback (most recent call last): File "/usr/bin/epkginfo-2.6", line 34, in <module> main(args) File "/usr/lib/python2.6/site-packages/gentoolkit/equery/meta.py", line 480, in main matches = find_packages(query, include_masked=True) File "/usr/lib/python2.6/site-packages/gentoolkit/helpers.py", line 535, in find_packages from gentoolkit.package import Package File "/usr/lib/python2.6/site-packages/gentoolkit/package.py", line 46, in <module> from gentoolkit.metadata import MetaData File "/usr/lib/python2.6/site-packages/gentoolkit/metadata.py", line 48, in <module> import xml.etree.cElementTree as etree File "/usr/lib/python2.6/xml/etree/cElementTree.py", line 3, in <module> from _elementtree import * ImportError: No module named _elementtree And so on.. This is why i think that dependency dev-lang/python:2.6[xml] is correct resolution until gentoolkit will be able to works with python3.
I guess we could add a USE setting to require xml support. It should be conditional since repoman is only needed for committing ebuilds, qa checks or generating manifests. We can also add a runtime check for xml support, and give a friendly error message it it's not detected. Also, we can generate an ewarn message in pkg_preinst if the selected version of python has no xml support.
Zac, is this bug a portage bug? The title indicates a gentoolkit one, but the content seems to point to repoman. Also is this still relevant?
We've had this runtime check in repoman for some time now: http://git.overlays.gentoo.org/gitweb/?p=proj/portage.git;a=commit;h=14ffb5c29f748114dd529d0c20e3c5fe6d953b5f
