Large file uploads
by Julian Pietron 24 Jul '10

24 Jul '10

Hallo, I'm currently realizing a web server for my company which allows control of some of our embedded devices. After some research, I decided on python and twisted as the way to go using genshi as templating engine, which works very well. The problem I encountered is as follows: The user of the web panel should also be able to upgrade the firmware on our device. To make this possible, a file upload has to take place. The firmware file can have a size of up to 150MB, so it will not fit in the RAM of our device. It either won't fit on the NAND flash chip twice, so it should be written to NAND with its final name and not as a temporary file. To tell the server where to store the file upload, I could add a hidden input to the upload form indicating the type of the file being uploaded, so that the web server can save it to the right location. Where's the place to hook in twisted to implement such a behaviour? Do I really have to write a completely independent implementation of the HTTP handler or could I also reuse some parts of twisted.web? Does some code exist already which implements the wanted behaviour or could be modified to implement it? Thanks for your reply, J. Pietron

Mirror Down
by Nick Holden 20 Jul '10

Hi, The main mirror for the twisted download is down, this is causing easy_install to hang for ages and fail when I try and install: " Reading http://tmrc.mit.edu/mirror/twisted/Twisted/10.0/ Download error: (110, 'Connection timed out') -- Some packages may not be found! Reading http://tmrc.mit.edu/mirror/twisted/Twisted/9.0/ Download error: (110, 'Connection timed out') -- Some packages may not be found! Reading http://twistedmatrix.com/projects/core/ Reading http://tmrc.mit.edu/mirror/twisted/Twisted/8.2/ Download error: (110, 'Connection timed out') -- Some packages may not be found! Reading http://tmrc.mit.edu/mirror/twisted/Twisted/8.1/ Download error: (110, 'Connection timed out') -- Some packages may not be found! " Any idea when it will be back up? Or any way to make easy_install or pip ignore the main mirror? Thanks! Nick Holden

Partial HTTP downloads using twisted.web.client.Agent
by Carlos Valiente 19 Jul '10

19 Jul '10

Hi! I need to download a fragment of a file using HTTP. The file is stored in several hosts, and I need to handle the case where one or several hosts are down, or do not have a copy of the file, or the connection fails for any other reason. Inspired by the Twisted client tutorial (http://twistedmatrix.com/documents/current/web/howto/client.html), I've written a function called ``download()`` (http://gist.github.com/481575) which iterates through a list of URLs. I find the resulting code a bit too long, however -- in particular the need for the ``FileWriter`` class. Have I overlooked some Twisted helper code, or some Twisted coding idiom, that could simplify the example above? Can you guys think of any way to improve that code fragment? Thanks a lot, C

https server example with client certs for twisted
by Gelonida 12 Jul '10

12 Jul '10

H, I posted this question already to comp.python.twisted just to discover a little later, that comp.python.twisted.web might be more appropriate. So here is my post again I'd like to implement a small https twisted server, which can wrap a wsgi module and which can verify client certificates I am able to do this with apache, but would like to do the same with twisted. (For some projects it would allow me to get rid of apache or to perform certain tests on a Windows hosts) What I have running is following shell script calling twistd #!/bin/sh certfile=mycert.crt keyfile=mycert.key wsgi_module=tw_wrapper.application twistd -n web --https 4433 \ --certificate $certfile --privkey $keyfile \ --wsgi $wsgi_module Basically I just use my wsgi script and didn't write any twisted code. My first step would be how to write the same twisted code without calling twistd The next step how to enforce enable client certificates I wondered where I could find any good example code implementing a web server with client certificate authentication ( and ideally with a subsequent wsgi module) TIA

Twisted 10.1.0 released
by Jonathan Lange 04 Jul '10

04 Jul '10

On behalf of Twisted Matrix Laboratories, I am honored to announce the release of Twisted 10.1.0. Highlights include: * Deferreds now support cancellation * A new "endpoint" interface which can abstractly describe stream transport endpoints such as TCP and SSL * inotify support for Linux, which allows monitoring of file system events. * AMP supports transferring timestamps Note also that this is the *last* supported release of Twisted for Python 2.4 on Windows. For more information, see the NEWS file. It's stable, backwards compatible, well tested and in every way an improvement. Download it now from: http://tmrc.mit.edu/mirror/twisted/Twisted/10.1/Twisted-10.1.0.tar.bz2 http://tmrc.mit.edu/mirror/twisted/Twisted/10.1/Twisted-10.1.0.winxp32-py2.… http://tmrc.mit.edu/mirror/twisted/Twisted/10.1/Twisted-10.1.0.winxp32-py2.… Many thanks to Glyph Lefkowitz, who helped do the release preparation, and the PyCon 2010 sprinters, who did so much of the work for this release. jml
