We still have to support older urlgrabber versions where the class
"URLGrabber" is an old-style class and therefore we cannot use a "super(...)"
call. This fixes issue #32
given urlgrabber version 3.9.1, MirrorGroup trys to access
grabber.opts, but the derived grabber OscFileGrabber hasn't
this attribute

Unfortunately the class URLGrabError does not define constants for the
different error codes therefore we have to hardcode the errno (alternatively
we can define them in our fetch module).
There are many places can't be covered by 2to3, especially the
str/unicode -> str/bytes change done in python3. This is a big patch
incorporating all changes made in order to make python3 suite.py run
without any single failure.
It
* adapt the introspect_handler_3 for case there are no __defaults__
* adds the ET_ENCODING variable for ET.fromstring ("unicode" in py3,
"utf-8" in py2)
* (re)adds various builtins to both python versions
- memoryview to python 2.6
- bytes compatible with py3 to 2.6 and 2.7
and it changes few parts of tests/common.py in order to be compatible
with python3
* new urlcompare method compares all components or url + parsed query
string in a dictionary, so the ordering, neither quoting does not matter
* bytes builtin has been added to 2.x and used in assertEqualMultiline
reintroduce unicode function - despite the fact I am pretty sure the
usage is plain wrong, because code says - return a unicode string from
utf-8 encoded one, which is probably not what was intended. I bet
something like encode the input as utf-8 was wanted.
raw_input has been removed and equals to input in py3. Unfortunatelly no
__future__ statement exists for that. Ensure all modules uses
osc.core.raw_input except osc.cmdln, where there is NameError way
implemented.
The most visible change in python3 - removal of print statement and all
the crufty
print >> sys.stderr, foo,
The from __future__ import print_function makes it available in python
2.6
Some modules (httplib, StringIO, ...) were renamed in python3. This
patch try to import the proper symbols from python3 and then fallback to
python2 in a case ImportError will appear.
There is one exception, python 2.7 got the io module with StringIO, but
it allow unicode arguments only. Therefor the old module is poked before
new one.
