Hi folks,
David Kirkby has suspected that ticket #6583 would break the build of
Sage on t2.math. I think I can now demonstrate that this is indeed the
case. Starting with Sage 4.3, at David's suggestion I created Sage
4.3.0.1 [1] with only #6595 applied. I then created six alpha releases

Thanks for the info ! So now the metalink is no more in the web page. Is there

The problem might be the lack of a __dict__ attribute:
sage: P. = QQ[]
sage: dir(P)
---
K. = GF(9)
K.
is also broken.
But it's not just parents:
ZZ. works
and it's not just the . syntax:
R. = Qp(5)
R. works

It seems to work for some objects but not others...
sage: P. = QQ[]

works as expected.

What's the right way to post a change to SAGE_ROOT/COPYING.txt (which

It mentions mwrank which is obsolete (we now use eclib which is

out of date.
