python 2.6 warning

python 2.6 warning

[-- Attachment #1: Type: text/plain, Size: 498 bytes --]

Hi all,
those who are using bitbake with Python 2.6 (e.g. Ubuntu 09.04, Debian
sid) will notice this warning:

/home/rschus/oe/bitbake/lib/bb/COW.py:29: DeprecationWarning: the sets
module is deprecated
  import types, sets

Is anyone from OE in the know how to fix that properly? I know its only
a warning but imagine an OE newbie reading this .... I would like to fix
it myself but even after years of contributing to OE my Pyhton skills
are severely limited. :|

Regards
Robert

Basically you need to rewrite COW.py to work with the new built-in sets. Might 
be a chance to get another BitBake release out.

:M:

Will this still work with python 2.5?

There were patches for this on the bitbake list. I suspect 2.5 will be
fine, not sure about 2.4 or earlier. I've not had a chance to look into
this yet :(

BitBake trunk has it fixed by me. Backporting to 1.8.x and to 
stable/2009 are on my todolist. And yes - it works fine with Python 2.5 
and even should with Python 2.4 which is minimal required version 
(should works with 2.3 but we do not support it).

It won't work with 2.3 but we don't care about 2.3, it will work with
2.4 onwards. I have no idea why we were using long deprecated stuff :/.

I've backported it to bitbake 1.8 and it seems to work along with
merging a number of fixes lurking in Poky.

I'm also intending to merge the virtual class extension stuff soon
unless anyone has a major objection (none were raised previously when I
proposed this).

Cheers,

Richard

+1. Have exactly the same fix locally.

Committed, thanks.

(after discussion on irc about why it was needed).

Can people please at least cc the bitbake list on bitbake patches as it
will increase the chances of me seeing them.

Cheers,

Richard
