[Nevow] about new guard in sandbox
by Manlio Perillo 03 Aug '06

03 Aug '06

Hi again. I have read the draft implementation of guard in Valentino's sandbox and I like it. However I have some questions: - why the ISessionMenager interface does not include a name attribute (since the default Session class uses the private _name)? - why Session.authenticatedAs has to be a property? - I think that there is no need to store tha password but only the username, so authenticatedAs -> avatarID - what's the use for the guard attribute in Session? - I think that ISessionManager should not have the loggedIn method. - as I can see the code in SessionManager._tick causes the log "Session %r expired" to be issued two times. - what's the use for mind in a web authentication? - why credInterface is a variable? It can be something different from IResource? - Session.sessionLifetime is only used on the server side but never set on the cookie. Only persistent cookies have a not null expiration date. - As I can see in SessionWrappper.locateChild the code request.session = session is executed twice (the first time in getSession. Thanks Manlio Perillo

FileSaver bug
by Alex Greif 02 Aug '06

02 Aug '06

Hi On windows XP (python 2.4.2) the latest svn checkout produces the following bug: FileSaver converts LF to CRLF automatically, even in binary files!! I tried to upload files with the following code: child_uploadfile = static.FileSaver(destination='d:/agreif/tmp', expectedFields=['filename'], maxBytes=10000000, allowedTypes=[http_headers.MimeType('text', 'x-python'), http_headers.MimeType('application','x-zip-compressed')]) here is the hexdump of two samples. You see that in front of every occurrance of "0A" a "0D" is inserted. Sample 1: textfile orig: 68616C6C6F0A uploaded: 68616C6C6F0D0A Sample 2 binary file (zip) orig: 504B03040A00000000001589FF34D13172B90500000005000000100000004E6575205465787464617465692E707968616C6C6F504B010214000A00000000001589FF34D13172B905000000050000001000000000000000010020000000000000004E6575205465787464617465692E7079504B050600000000010001003E000000330000000000 uploaded: 504B03040D0A00000000001589FF34D13172B90500000005000000100000004E6575205465787464617465692E707968616C6C6F504B010214000D0A00000000001589FF34D13172B905000000050000001000000000000000010020000000000000004E6575205465787464617465692E7079504B050600000000010001003E000000330000000000 Alex.

Re: [Twisted-web] documentation -- Techno Turkey's fifth adventure
by lloyd＠paisite.com 01 Aug '06

Hi Folks, Sounds like I kicked off a vital and worthy discussion with my questions/request re: development environment. Very exciting! My instincts tell me that it'w worth letting this discussion run it's course for another couple of days until we arrive at a consensual plan-of-attack. Best I can contribute is a summery of suggestions to date: Development Environment: -- Valentino suggests we take a look at: > An alternative for Nevow is using Combinator (explained in the Divmod > Combinator page): http://divmod.org/trac/wiki/DivmodCombinator > Another alternative for Nevow is using setuptools although I'm unsure how > working itis. Yet another for both is using .pth Twisted Coding Standards -- Valentino also suggests we review: > http://twistedmatrix.com/projects/core/documentation/howto/policy/coding-st… -- glyph suggests: There is actually an under-maintained Axiomatic plugin in Mantissa which helps with this somewhat; it probably doesn't work at the moment, but check out "axiomatic mantissa". It might help with this kind of setup, or at least provide some ideas for tools to expedite the turkey's adventures. Directory Structure -- Daniel says: > While you are correct that no specific directory layout conventions have > been blessed by the core development team, I think that there is a lot of > value in providing one, if only to give really new users some kind of > structural anchor point from which to begin learning web-app development > with twisted. (Speaking for the turkey contingent, I heartily agree.) -- Daniel suggests: /ProjectName /packagename /static /css /js /images module1.py module2.py ... -- Valentino counters: /ProjectName /static /i - images /s - styles /j - javascript /template /doc /database - sql files /bin - various scripts /projectname - python modules /web - for the web stuff /storage - for the data layer /other_eventual_twisted_using_subparts common_python_modules.py -- Manlio asks: > An interesting question is: when one should consider the option of serving > static content with a server like lighttpd, and forward with mod_proxy > requests for dynamic content to twisted web? > static.File is a no match versus lighttpd, but there is the overhead of > mod_proxy and one should also consider how to design the site layout at > the best. .pth vs. PATH -- Daniel says: > I suggest using .pth files rather than path variables. Using .pth files > should "just work" regardless of your OS, and not require any fiddling > around with the environment by hand. > So, basically, for a new web project, you'd create your project dirs, and > then stick a "myproject.pth" file in the site-packages directory, > containing "/path/to/my/project/topmost/folder" Testing development environment > To test that the dev environment is set up correctly, I'd just start up a > python interpreter prompt and import twisted, then import nevow, and > lastly, import myprojectpackage. Running Twisted code -- Daniel suggests: > I probably sound like a broken record, but I'd suggest offering one, and > only one, way to run the code, so that users aren't fiddling with things > that are not central to grasping the concepts being presented. > Me, I use .tac files for everything these days, so that's what I would > recommend for use within the tutorials. Seems to me that these are all open questions worth consideration and further discussion and clarification. As soon as we have some degree of mutual understanding and concensus, we can discuss how to implement the Turkey's Guide for Diving into Twisted or whatever we decide to call it, as well as where to put it. Meanwhile... I'll post the next draft of Dialtone's Resource Magic on http://twisted.paisite.com, incorporating suggested changes. Many many thanks to all. Best wishes, Lloyd

Dos and Don’ts of Client,Authentication on the Web
by Manlio Perillo 31 Jul '06

31 Jul '06

I have found this article on the web: http://pdos.lcs.mit.edu/cookies/pubs/webauth:tr.pdf And: http://www.acros.si/papers/session_fixation.pdf Among the other things, the second article claims (if I'm not wrong) that url based sessions are not more secure that cookies. The first article explain the importance of not to leak the user's passwords (so I need to login on SSL, this makes the default implementation of guard not usable). Regards Manlio Perillo

beginners question
by Alex Greif 31 Jul '06

31 Jul '06

Hi NG, I am completely new to twisted, but want to give it a try :) I have a small website running, serving dynamic content with Pylons. For switching to twisted, do I have to use the web or the web2 module? thanks, Alex.

[Nevow] JavaScript code
by Manlio Perillo 31 Jul '06

31 Jul '06

Hi. In the Nevow source distribution there are some JavaScript code but I don't understand what files are actually used. As an example there is defer.js script, but there is also a deferred support in MochiKit. Thanks Manlio Perillo
