Re: [Merge] lp:~statik/txaws/here-have-some-s4 into lp:txaws
Wow, code explosion. Uhm, This perhaps would be easier to review in
Firstly, the module should be txaws.storage.simulator, I think. Or
Secondly, copyright headers. txaws does a much leaner one;
# Copyright (C) 2009 $PUT_YOUR_NAMES_HERE
# Licenced under the txaws licence available at /LICENSE in the txaws
Please use that - it prevents skew between different modules.
See txaws/ec2/client.py, for instance.
Thirdly, I'm not sure what python versions we're aiming for. I note that
the simulator code depends on 'with', which carries an implicit version
requirement. Please document the version that the simulator supports
both in /README and perhaps the docstring for the simulator.

This is a problem :). I'd much rather see code land without having a
boto dependency at any point: boto is rather ugly, and the code will
likely be a lot nicer right from the get-go if we don't have it.

see above - the location doesn't fit with the txaws source layout. This
is a storage server module (contrast with txaws.storage.client).
Having a README in a python module is odd. The content would be better
put in the __init__.py's docstring, so that pydoctor etc can show it.

Given that this is a twisted process, it would be nice for the docs to
'to start: twistd -FOO -BAR -BAZ' rather than referring to a shell
script which by its nature won't work on windows.

What is this file for? how is it used? It looks like a lot of
duplication with existing code in txaws.
The different (C) terms means it will need to be mentioned in some way
at the top level portion.
I suspect we need to add an AUTHORS file too.

I've skipped most of this file pending the boto dependency being
removed. But I thought I'd mention that this fragment above is highly
redundant with shipping a tac - it shouldn't be needed at all.

Again, I've largely skipped this file - the review is huge and I don't
want to make you wait to start getting it ready for me to have time to
read the entire thing.
embedding a comment like this in the code makes the code harder to read.
Putting it in some actual documentation somewhere would be better (or
even just reference the AWS spec).

I really don't like this style of adhoc testing - please write a unit
test and have it perform a string equality, if thats needed. Otherwise
its dead code - it won't be checked regularly, can skew and thats a
problem. Or if its not a problem, we don't need it at all :).

Calling this 'test_support' would make it clearer that its not tests.

This is a bit of a smell - why do we need to use threads in testing this

This boilerplate isn't needed:
python -m unittest <module> is precisely equivalent to that.
