Comment:
I'm looking at the proposed sage-latest-online-package script and have
some comments.
I don't really like the 'list.tmp' temporary file business. It's nice to
check if the user has the permissions to upgrade, but I think doing so
should be the job of whatever actually does the upgrade. The name of the
script implies that it tells you the latest online package name, and I'd
like to see it do ''only'' that.
I see that urlretrieve always uses a temporary file automatically (which
gets deleted automatically), so perhaps we could do the first part of
spkg_list like so:
{{{
web_url = "%s/%s"%(PKG_SERVER, url)
fn = urllib.urlretrieve(web_url)[0]
r = open(fn).read()
[etc]
}}}
Also, when you build the list of spkgs, why do list(set(..)), then sort
the list? The listings are alphabetized anyway, and if we run into a
duplicate, the script will exit on the first occurrence anyway. It looks
like just this will be fine:
{{{
return [x.strip()[:-5] for x in r if x.endswith('.spkg')]
}}}
instead of
{{{
v = list(set(...))
v.sort
return v
}}}
With the above changes, the script seems to work fine. I'd like to know if
anyone uses a nonstandard SAGE_SERVER so we can make sure the script still
works for such cases.
