[sage-devel] Re: Sage notebook blocker
When you just do "sage -notebook" you are logged in with a token as password since Sage spawns the browser. So you actually do log in, its just automatically behind the scenes. This is not an option for the virtual machine, you can't start a host browser from within the VM. The following does not work: sage -notebook interface=\'\' port=8002 open_viewer=False require_login=False When you manually open http://localhost:8002 you are greeted with a login screen.

[sage-devel] Bug in Graph.matching
I think I've discovered a bug in graphs/generic_graph.py: sage: g = graphs.PathGraph(3) # an unweighted graph sage: g.matching(value_only=True, use_edge_labels=True) # I get 1.0 sage: g.matching(value_only=True, use_edge_labels=False) # I get 2 Here's the problem area, around line 6786: d = networkx.max_weight_matching(g) if value_only: if use_edge_labels: return sum([weight(self.edge_label(u, v)) for u, v in d.iteritems()]) * 0.5 else: return Integer(len(d)) Since networkx.max_weight_matching returns a dict with a key for each vertex that is the endpoint of an edge in the matching, it seems like that last line should be "return Integer(len(d)/2)"?

Re: [sage-devel] Re: one doctest fails on ubuntu 12.04
Hi, Just an update. The test I mentioned is still failing and the last few lines before failing is - $ sage -t --long -force_lib "devel/sage/sage/modular/modform/find_generators.py" ... /home/rajeev/software/sage/local/lib/libatlas.so(ATL_dJIK52x52x52TN52x52x0_a1_b0+0xac)[0x7faffeb7426c] Unhandled SIGSEGV: A segmentation fault occurred in Sage. This probably occurred because a *compiled* component of Sage has a bug in it and is not properly wrapped with sig_on(), sig_off(). You might want to run Sage under gdb with 'sage -gdb' to debug this. Sage will now terminate. Segmentation fault (core dumped) I thought that there might a problem with atlas install, so I installed nose and ran the tests for numpy and scipy and all the test pass, so I guess atlas install is fine.
