[arch-dev-public] The "Great Python Rebuild of 2010" begins

[Allan McRae]

Hi,

I have pushed the new python (3.1) and python2 (2.7) packages to the new 
[staging] repo so rebuilds can start there.   Remember the staging repo 
should never be used outside a build chroot...  If you do, everything 
python related will break on your system.

TUs will not be able to start uploading rebuilds yet as they do not have 
a staging equivalent, but we will sort something out for them once we 
get all the db-scripts/devtools changes tested for the main one first. 
The package pool is going to save us a heap of issues when this gets 
moved so it is worth the wait.


The key things to remember with the rebuild are:

  - build in clean chroots.  Most packages will detect "python2" or 
"python-2.7" once they see no "python" and use that.  Some will need 
simple patching.

  - change your dependencies to python2

  - check files for #!'s with "/usr/bin/python" or "/usr/bin/env 
python".  If you have those you will need to do a sed to change them to 
python2.


If you come across a package that you can not easily fix, add it to 
http://wiki.archlinux.org/index.php/DeveloperWiki:Python_Todo_List#Packages_with_rebuild_issues 
and I will take a look at it.

Have fun,
Allan
