[Twisted-Python] newpb 0.0.1 is released!

[Josh Ritter]

Excellent!

It's great to see newpb emerge from the shadows :)

We use spread extensively in our game Minions of Mirth.  Security and 
*performance* are key areas for us.

Thanks!,

> I'm pleased to announce that the first alpha release of "newpb", a 
> ground-up
> rewrite of twisted's native RPC protocol, is now available.
>
> Years in the making, newpb offers a variety of new features, more flexible
> serialization than oldpb, a better security model, and the potential (not 
> yet
> achieved) to be faster. For a larger list of new features, take a look at 
> the
> newpb wiki page[1].
>
> The release itself is currently available from my web directory[2]. At 
> some
> point in the near future, it should also be available from the Twisted
> downloads directory, and from the download mirror sites as well. To use 
> the
> release you will have to install it with the usual 'setup.py install'
> incantation: it adds a 'twisted.pb' module to your regular twisted
> installation, and as such it won't work if you just add the unpacked
> directory to your PYTHONPATH.
>
> Please note that this is an ALPHA release. Think of it as a technology
> preview. The wire protocol is *not* stable yet, which means that a
> newpb-0.0.1 client is unlikely to be able to talk to a newpb-0.0.2 server,
> etc. Don't deploy it anywhere unless you will be able to upgrade both ends 
> of
> the wire in the future. There are likely to be significant bugs (including
> security holes) present, and some major design decisions still remain to 
> be
> settled. For production systems, please continue to use oldpb (aka
> twisted.spread, as distributed in TwistedCore) for the forseable future.
>
> That said, it's high time that people get a chance to play with this code. 
> An
> earlier version of it leaked into the TwistedCore-2.2.0 release before 
> anyone
> could catch it (but truth be told the code there is almost identical to 
> this
> 0.0.1 release), but apart from that it has been languishing in SVN[3] for 
> far
> too long. I think I've been working on this intermittently for three 
> years,

> usable

> The top-level "Getting Started" documentation, with examples, is in
> doc/pb/using-pb.xhtml, of which a lore-rendered version is in my newpb
> webspace[4]. There are a number of protocol specification documents in 
> there
> too. There are also lists of outstanding jobs and open design questions in
> doc/pb/*. The 8.5kloc of code lives in twisted/pb/*, along with an 
> additional
> 4.7kloc in the 229 unit tests.

> Naming: the name is still in flux. We've been using "newpb" as a working
> title, to distinguish it from "oldpb" (which is the twisted.spread that's
> been shipping in TwistedCore since forever). "pb2" is another working 
> title.
> It will probably have some new name in the future, hopefully one which

> When filing bugs and tickets, if you see a 'pb2' component in Trac, please
