Hi, I have some code that takes file uploads from browsers. I'm trying to write a test for it, so now I need to get Twisted to do file uploads like browsers do. I think my code (not test code) essentially works, by manually trying it with a browser. I can't get the functional test part to work.
I have reduced the problem to what I think is a SSCCE. render_POST drops into a debugger to easily inspect the received request. Here's the code: https://gist.github.com/3058974 When debugging this with wireshark I found an obvious culprit: there's some random junk in front of it (3 ASCII hex digits and a CRLF) and some junk at the end (CRLF and an ASCII "0", although I'm not sure if that CRLF is junk). Wireshark reports some broken TCP packets (PCAP attached). I have no idea why that happens. Packets were captured with: tcpdump -i lo0 -nn -s0 -w sample.pcap port 8080 and analyzed with a recent version of Wireshark (1.6.2, SVN rev 38931). The analyzed TCP stream is also attached.

Description: Binary data
If I look at the request in the debugger (request_POST *DOES* get called…): - it has an empty request.args, instead of having the expected keys "a", "b", "f" - request.content.getvalue() has the data you see in tcpdata.txt: it starts with "'1e7\r\n------------" even though I obviously would like it to start with just the dashes cheers lvh
