[sage-cloud] Re: How do i remove overtype?

[Dima Pasechnik]

it is not clear what kind of Sagemath interface you were using; e.g., if 
you used a "usual" text editor then it's a question about this particular 
text editor (e.g. if you used vim then you should consult vim manual).
If it was SMC (SageMath cloud) then this question should be asked in 
sage-cloud Google Group, and not here.
I cc there, just in case.

Hi, right now it doesn't make sense, since that list is neither final
nor intended for the current setup. I'm working on a new setup and
that list is part of a quite large test suite to make sure, that the
installed software is actually there (e.g. important python, R and
julia packages can actually be imported, etc.)

In the future, once that's fleshed out, this list should definitely be
somewhere more visible. It will be served from somewhere else,  and
should also get a bit of love regarding styling and layout.

Re: [sage-cloud] Installation Problems

[Robert Lowe]

Another part of the puzzle has emerged.  I can get access to raw files 
through the proxy if they are in a publicly shared folder.  However, if I'm 
doing a raw pull within a project in a non-public folder I get a bad 
gateway.  

This tells me something is going on inside smc, probably with an 
authentication token of some kind.  I noticed in proxy.coffee that it looks 
like that is how it determines if it serves a file or not.  The section in 
question reads:

if not misc.path_is_in_public_paths(path, public_paths)
# The requested path is not public, so nothing to do.
cb()
else
# The requested path *is* public, so we get the file
# from one (of the potentially many) compute servers
# that has the file -- (right now this is implemented
# via sending/receiving JSON messages and using base64
# encoding, but that could change).


It's non-obvious whether the earlier code in proxy.coffee can handle an 
authenticated user's files.  I assume it can, as this capability exists in 
the live cloud.sagemath.org server.  Alternatively, perhaps the master 
branch code is not actually the code currently running on SMC.  When I try 
manually talking to the proxy, and I send the same header sent by my web 
browser, I get a blank response.  The proxy doesn't even send a header 
back, which tells me that we are likely visiting this segment of the code 
even while authenticated.

I'm also beginning to think I'm alone in this, and once I do figure it out 
I will join an elite group of individuals who have managed to install SMC.
