Description FTBFS 2010-06-03 17:19:37 EDT
python-lxml-2.2.6-1.fc14.src.rpm Failed To Build From Source against the rawhide tree.  See http://fedoraproject.org/wiki/FTBFS for more information.
If you believe this is actually a bug in another package, do NOT change the component in this bug or close this bug.  Instead, add the appropriate bug number from the other package to the "Depends on" line in this bug.  If the other package does not yet have a bug created that you think matches, please create one.  Doing so helps us properly track bugs and their dependencies, just as we track package dependencies.  (If you close this bug, and the other package is not fixed before the next FTBFS run, a new bug will get created.  Please follow the above advice to avoid such duplication.)

Comment 8 Dave Malcolm 2010-06-03 17:26:51 EDT
The 2to3 traceback is with python-2.6.5-12
Comment 9 Dave Malcolm 2010-06-03 17:47:52 EDT
Adding --verbose to invocation of 2to3 indicates the problem is when running on:

The issue appears to be the line:
  from itertools import *
Comment 10 Dave Malcolm 2010-06-03 17:53:26 EDT
I believe the only two names from itertools that are used are "islice" and "repeat", so this could be replaced with:
  from itertools import islice, repeat

Looks like 2to3 could handle this better, if only by giving a better error message.
Comment 11 Dave Malcolm 2010-06-03 18:23:07 EDT
2to3 issue filed upstream as http://bugs.python.org/issue8892
Comment 12 Dave Malcolm 2010-06-03 18:59:09 EDT

Patch the various "from itertools import *"

Attached patch changes various lines of the form 
  from itertools import *
to instead list the specific names to be imported.  I may have got the lists wrong.

With this patch 2to3 from python-2.6.5 works
Comment 13 Dave Malcolm 2010-07-26 09:06:23 EDT
I've cherrypicked the lib2to3 patch from upstream, rebuilding python into dist-f14-py27-rebuild as python-2.7-6.fc14:

Comment 15 Dave Malcolm 2010-07-26 11:28:03 EDT
Relevant code looks like this:

> def open_http_urllib(method, url, values):
>     ## FIXME: should test that it's not a relative URL or something
>     try:
>         from urllib.parse import urlencode
> from urllib.request import urlopen
>     except ImportError: # Python 3
>         from urllib.request import urlopen
>         from urllib.parse import urlencode

Clearly the "from urllib.request import urlopen" is at the wrong indentation level
Comment 16 Dave Malcolm 2010-07-26 11:28:49 EDT
To clarify, this is in the generated:
and looks like another 2to3 bug within the python 2 package.
Comment 17 Dave Malcolm 2010-07-26 11:56:54 EDT
Relevant input code, before 2to3 is invoked:
> def open_http_urllib(method, url, values):
>     ## FIXME: should test that it's not a relative URL or something
>     try:
>        from urllib import urlencode, urlopen
>     except ImportError: # Python 3
Comment 18 Dave Malcolm 2010-07-26 13:29:52 EDT
Filed the 2to3 bug upstream here:

Workaround for now may be to fix it up in lxml so the import is two separate lines.
Comment 19 Dave Malcolm 2010-07-26 14:35:33 EDT
I've patched around this in python-lxml for now, as proposed in comment #18
