Get identity of previously-authenticated user
by Mike Pelletier 23 Apr '11

23 Apr '11

twisted.web.template is great to have. I'm doing a client's web app project with (so far) just twisted. So far the only thing I really miss from nevow is that I cannot load a template from a fragment identifier in an xml document, but just for reasons of convenience. I need to know who is logged in. Twisted offers twisted.web.guard.HTTPAuthSessionWrapper to perform the initial authentication, but then when a page element wants to know the identity of the authenticated user, there seems to be no provision for this. Furthermore, there seems to be no place in the classes I am invited to write to work with twisted.web.guard where both the request object and the avatarId exist at the same time. The only opportunity I have to bind a user identity/object to a request is by constructing and throwing away a new Resource tree for each request in requestAvatar. I decided that was probably not what I was meant to do. Instead, I have done something that turns out to smell very bad to solve this problem. What was the correct solution? Mine was to subclass HTTPAuthSessionWrapper and override _authorizedResource and _login in order to pass the request object as the mind. From there I can use request.setComponent in requestAvatar and request.removeComponent in the logout callback (just for fun) to associate an authenticated user object with the request. I'm not even sure that's what "mind" is for, and it's not cool copying and pasting the body of a couple of methods out of the library. My next task appears to be to write a credential factory that can take credentials out of the cookies or session, to support a friendly login interface. Again I feel as though I am whacking my way through what should be a clear trail. It's dangerous stuff to be writing as application code. Am I just expecting too much from twisted.web a la carte? Is nevow a viable choice anymore? TIA for just one or two lines of wisdom. --Mike

producer-consumer example with web requests
by Ilja Livenson 18 Apr '11

18 Apr '11

Hi, I wonder if someone could help me with making of a streaming proxy - I understand how producers/consumers work with general twisted, but unsure of the best strategy in case of twisted.web. So, the problem is as follows: frontend that accepts a request with some headers I must process and a potentially large body. The latter I'd like to be able to proxy in a streaming manner to another http server. Any suggestions? thanks, Ilja

Creating a hybrid server in Twisted
by Jashank Jeremy 06 Apr '11

06 Apr '11

--text follows this line-- Hi, I'm trying to write a hybrid server that serves either HTTP or my own custom protocol depending on how it's addressed (distantly inspired by the IRC bouncer ZNC). If it receives a standard GET, POST, HEAD, etc. it sends HTTP traffic, or if it receives the bareword `CORDELIA', it switches to Cordelia mode. HTTP works fine with Twisted.Web. I can serve pages over HTTP (which is my desired outcome). However, I'm not sure how to write the Cordelia handling code. I've tried my own custom `render_CORDELIA' function, but it acts too much like HTTP (ie. it returns a result and terminates the connection), which is not what I want, as the protocol I've designed involves establishing a two-way conversation, not a single request and response pair. So I'm pretty much stuck in a rut. I don't want to totally reinvent the wheel just to be able to protocol-switch; I'd prefer to make use of existing code from Twisted. How do I hijack Twisted.Web to add protocol switching? Jashank -- Jashank Jeremy PGP: 0x25A5C309

<lvh> PAS MAINTENANT CHEF! CHUIS EN TRAIN DE BRANCHER LE REACTEURRRRR On behalf of Twisted Matrix Laboratories, I am honored to announce the release of Twisted 11.0.0. Highlights include: * a new templating system in Twisted Web, "twisted.web.template", derived from Divmod Nevow. * improved behavior of subprocess spawning on FreeBSD. * the 'twistd mail' plugin now uses the endpoints API, providing a more consistent command line and compatibility with endpoint plugins. * twisted.plugin no longer emits a confusing traceback when it can't write a cache file. and numerous other bugfixes and documentation improvements. For more information, see the NEWS file. Download it now from: <http://twistedmatrix.com/> or install the 'Twisted' package from PyPI. Many thanks to Glyph Lefkowitz and Jean-Paul Calderone for sanity-checking the pre-releases and release, and to the enthusiastic PyCon 2011 sprinters who annihilated dozens of tickets. Thanks to *everyone* who contributed tickets, patches, documentation, reviews, buildbots, feedback, and assistance to fellow users and developers leading up to this release. It is truly a group effort. <http://twistedmatrix.com/highscores/?time=2011-03-01> is a testament to how much work was done in March alone. -Jessica
