Re: [sage-devel] sage infrastructure at UW
I don't think that anyone is making a case specifically against French Universities any more than they are making a case against American univerisities. Some of us now have now had bad experiences on both sides of the Atlantic (specifically France because they do host a lot of Free Software infrastructure, not because they are French). For example, I have had tickets and emails ignored for almost a year in one case. University admins the world over are not equipped to support large Open Source international projects as reliably as we'd like. William is 100% right here. We should not be relying on specific universities, especially when that would add to the load of sysadmins who will just end up ignoring tickets, even when there is a system explicit set up to deal with such problems.

Sorry, I didn't fully appreciate your comment above when I first read it. I
agree, this is fairly compelling.

I would also say "No". The reason is that if that is what the user
wanted, he could just have done "from mytest import *". If he explicitly
does "import mytest" it's because he wants the control over the
namespace.

Sage doesn't do this either. If you load a normal Python interpreter,
'import sage' does not do this. It just happens that the specialized
sage interpreter does that at startup time, but that's not normal
behavior for a Python package.
If there's a way to detect if you're in the sage interpreter it
*might* be okay to do this only in that case depending on how other
sage users feel (I don't know). But otherwise it's something that
should be specified manually in init.sage.

Well, actually, if some one explicitly loads the package using something
like "import mytest" then I think that it is reasonable to load the main
functions from the package it the global namespace. Thinking about it, sage
already does something similar (but more explicit) with methods like
inject_shorthands. Drilling down a little I realised that I can do what I
want by putting the following into my __init__.py file:
from sage.misc.misc import inject_variable
from mytest.test import atest
inject_variable('atest',atest)
*Question*: do people think that it is reasonable for a package to do this?
Arguments against include that packages "shouldn't force the user to load
the functions into
the global namespace" and that this may lead to clashes in the namespace.
An argument in favour of doing this is that this a more user-friendly and a
user is unlikely to import a package if they don't want to use it.

Re: [sage-devel] Global namespace and independent python packages
Hi Andrew, To import into the global namespace use sage: from mytest import * As a package author, you shouldn't force the user to load the functions into the global namespace. However, it might be possible by getting hold of the globals() object or something. If you want to import the package into the global namespace *on your own setup*, you could put the "from mytest import *" in the file ~/.sage/init.sage.

[sage-devel] Global namespace and independent python packages
I have been playing around with ta stand-alone python package for sage. It works really well except that I have not found a "nice" way to import classes into the global namespace. I suspect that it is just something in the way that I have configured things, so I've distilled my code down to a minimal example in the hope that some one can tell me how to fix it. My package layout is: package/ |- setup.py |- mytest/ |- __init__.py |- test.py where the files setup.py, __init__.py and test.py are as follows: *setup.py* from setuptools import setup setup(name='mytest', packages=['mytest']) *__init__.py* from __future__ import absolute_import from .test import atest from mytest import * *test.py* def atest(): print 'A working test' To install this "package" you can either use plain setup tools with sage setup.py install but I decided to pip instead, installing it "locally" and in development mode with: sage -pip install -e --user . This works fine in that I can start sage and import and use the package, but not quite as easily as I'd like: sage: import mytest sage: mytest.atest() A working test sage: atest() --- NameError Traceback (most recent call last) in () > 1 atest() NameError: name 'atest' is not defined sage: from mytest import atest # manually import atest sage: atest() A working test I thought that `atest` would be automatically available from the global namespace because of either the second and or the third lines of __init__.py. Instead, it still needs to be manually imported. Is there a way to put atest into the global namespace when the package is imported? Of course, it would be even better if the mytest package was automatically imported into the global namespace at run-time.

On trac.sagemath.org there is also a hack that allows one to remain logged in (for a period of time?). More precisely, even if you log out, you can still log in without filling in the creds (and no, creds are not stored by the browser in its password manager, it's something else).

Thanks for pointing it out, it's on my to-do list to fix. (I am confused why it has URL in the config files I got off the UW machine, but I don't get that prompt on the current trac.sagemath.org). In other words I know where it comes from, but I don't know why that value is there. > On Wednesday, June 8, 2016 at 5:03:47 PM UTC+1, Erik Bray wrote: >> >> On another note, I have a copy of trac.sagemath.org up and running on >> GCE here: http://104.197.143.230/ >> >> In the process of setting it up I also upgraded to the latest Trac >> version (1.1.6).

Erik, the trac login prompt (on Safari) displays the following message: To view this page, you must log in to area “sage.math.washington.edu” on 104.197.143.230:80. Don't know where it digs that "area" hostname from, but it definitely makes no sense.

[sage-devel] Re: Sage at 2016 MAA Project NExT Networking Lunch
