[with patch, needs review] notebook -- user management features

Depends on #4134 and #2407

I'm trying to review this, but I can't get the patches to apply. I'm starting from a clean 3.1.2 tree. Which patches should I apply, and in what order? Should I use a different version to apply patches against?

This ticket has been rebased.

It seems that the /user page isn't found with an existing notebook. I created a new notebook and the /users page came up.

I've had trouble in the pass with getting administrative users recognized by the Notebook.

I've applied all the necessary patches to a 3.1.3alpha1 tree, but when I try to start Sage, I get:

/var/tmp/sage-3.1.3.alpha1/local/lib/python2.5/site-packages/sage/server/notebook/twist.py in <module>()
   1935     return False
   1936 
-> 1937 from sage.server.notebook.template import registration_page_template
   1938 from sage.server.notebook.template import login_page_template
   1939 

/var/tmp/sage-3.1.3.alpha1/local/lib/python2.5/site-packages/sage/server/notebook/template.py in <module>()
     38 templates = ['login', 'yes_no', 'failed_login', 'register', 'admin_add_user']
     39 for name in templates:
---> 40     G[name + '_template'] =  PageTemplate(pjoin(path, '%s.template'%name))
     41 
     42 def login_page_template(accounts, default_user, is_username_error=False, is_password_error=False, welcome=None, recover=False):

/var/tmp/sage-3.1.3.alpha1/local/lib/python2.5/site-packages/sage/server/notebook/template.py in __init__(self, filename)
     27 class PageTemplate:
     28     def __init__(self, filename):
---> 29         file = open(filename, 'r')
     30         self.__template = Template(file.read())
     31         file.close()

IOError: [Errno 2] No such file or directory: '/var/tmp/sage-3.1.3.alpha1/data/extcode/notebook/templates/admin_add_user.template'

That's just the last part of the traceback; the rest doesn't seem so interesting...but let me know if you want to see it.

I've looked through the patches from 4134, 2407, and this ticket, and I don't see where the file admin_add_user.template is created. I have all those patches applied (except 4134, which has already been merged); how do I get that file?

Replying to ddrake:

Did you do hg_extcode.apply('http://trac.sagemath.org/sage_trac/attachment/ticket/4135/extcode-4135_1.patch')

Or if you're using queues and don't want to mess up your tree, go to $SAGE_ROOT/data/extcode and do:

hg qinit
hg qimport /path/to/extcode-patch
hg qpush

Timothy, what is the relationship between this patch and #3923, #3937, and #3949.

Apply just extcode-4135_1.patch and sage-4145_3.patch

Depends on #3950

Don't apply extcode-4135_1.patch afterall
