python 2.4

[Fab]

Hi,

I am not sure, how hard it is, but is there a chance that the
commander works with an old python 2.4 version as well? I would like
to use the commander on a remote cluster, which has still the old
version of python (actually I think like a lot of clusters). As xyzcmd
is especially useful for such remote usage, this would be quite nice.

Best Regards!

Hello!

Sure, I've already thought about this. In fact there are only two
2.5-specific features in use: inline if-else form and some 'with'
statements.
I'll make it for 0.0.3.

Ok. I've commited python2.4 support to trunk.
I haven't tested it in great detail, but looks like it works.

P.S. The code appears much more uglier with those old 2.4 constructs :)
For example 2.5 code:

return (self.active if active else self.inactive).get_selected()

was replace with:

if active:
obj = self.active
else:
obj = self.inactive

return obj.get_selected()

But nevertheless, it was worth it ;)

Hi Max,

thanks!
Unfortunately, I a have some problems with the installation (testing
it on a current kubuntu/karmic). I am not sure, what I did before, but
right now I get this
error:

ceplx049~$ xyzcmd

Traceback (most recent call last):
File "/usr/local/bin/xyzcmd", line 25, in <module>
Launcher().run()
File "/home/gcae504/HOME/Software/xyz/lib/python2.6/site-packages/
libxyz/launcher.py", line 97, in run
self.xyz.screen.run_wrapper(self._run)
File "/home/gcae504/Desktop/urwid-0.9.9/urwid/raw_display.py", line
234, in run_wrapper
return fn()

libxyz/launcher.py", line 115, in _run
panel = uilib.Panel(self.xyz)
File "/home/gcae504/HOME/Software/xyz/lib/python2.6/site-packages/
libxyz/ui/panel.py", line 46, in __init__
self.conf = self.xyz.conf[u"plugins"][u":sys:panel"]

I used the build.sh script, unpacked the bzip file and run python
setup.py install.
A second try with adding:

/usr/local/lib/python2.6/dist-packages/

to the pythonpath gives:

ceplx049~$ xyzcmd
Traceback (most recent call last):
File "/usr/local/bin/xyzcmd", line 23, in <module>

line 29, in <module>

File "/usr/local/lib/python2.6/dist-packages/libxyz/core/
__init__.py", line 31, in <module>

ImportError: No module named odict

I am probably doing something stupid... do you have a hint!?
Thanks!

You are using python2.6 and urwid-0.9.9, right?
I'll try to reproduce this problem today.

Ok. I think I found it. The error occurs due to wrong system directory location.
xyzcmd thinks it is sys.prefix + share/xyzcmd, on ubuntu 9.10 (or with
python-2.6) the installer mistakenly installs system files to
/usr/local whereis python sys.prefix points to /usr.
I'll correct installer soon but in the meantime you can make symlinks
from /usr/local/share/xyzcmd to /usr/share/xyzcmd and from
/usr/local/lib/python2.6/dist-packages/libxyz to
/usr/lib/python2.6/dist-packages/libxyz or wherever your python
sys.prefix points to.

After googling a bit more, I've found that this is an ubuntu python
(distutils) issue
(https://lists.ubuntu.com/archives/ubuntu-devel/2009-February/027439.html)
and instead of manually creating symlinks you can just install xyzcmd
with:
setup.py install --install-layout=deb

I think it is time for creating distro-specific packages ;)

Hi Max,

thanks for your help! It works now.. on the cluster as well :-)
Is there an option to change the installation path? I know, the --prefix
one, but this does not change the SYSTEM_DIR in config.py. I set it now
by hand.

Regards!

[Max E. Kuznecov]

Yup, currently it's kinda mess with installation prefix, I'm creating
a ticket to resolve the problem once and for all.
