---------------------------+------------------------------------------------
I'm posting an spkg to update Python from 2.6.2 to 2.6.4. The changes
from the previous spkg: in spkg-install, I have removed the lines
{{{
# This tells Bash to exit the script if any statement returns a non-true
# value.
set -e
}}}
Reason: in this part of the script, we want to test the return values and
print a helpful message if they're not true, rather than just exit
silently.
I've also removed the patch for the file {{{src/Lib/ctypes/__init__.py}}},
because I think it only deals with Mac OS X, 10.3 or earlier, and we don't
support that. Does Sage even build on pre-10.4 systems?
I looked at the other patches, and I think we still need them, but I'm not
an expert. (I tried removing the pickle patches, for instance, and got
lots of doctest failures.)
I've added a patch file for socket.py: what we're patching hasn't changed,
but in the previous spkg, there wasn't a patch file recording it.
The spkg is here:
[http://sage.math.washington.edu/home/palmieri/SPKG/python-2.6.4.p0.spkg].
With this spkg, I see one new doctest failure, but I don't know if it's
significant. If it's not significant, it's easy enough to fix the
doctest. It's for {{{sage/misc/explain_pickle.py}}} -- see the last line
("(cPickle raised an exception!)"):
{{{
