Package: pyblosxom
Version: 1.2.1-2
Severity: normal
Tags: patch
When handling HTTP POST requests, PyBlosxom doesn't honor CONTENT_LENGTH
CGI variable and expects EOF. Some HTTP servers (like bozohttpd)
doesn't send EOF at the end of the body. Although inconvenient, this
behaviour is compliant to CGI 1.1 specification [1]:
The server will send CONTENT_LENGTH bytes on this file
descriptor. Remember that it will give the CONTENT_TYPE of the data
as well. The server is in no way obligated to send end-of-file after
the script reads CONTENT_LENGTH bytes.
PyBosxom hangs (seems to wait for EOF forever) when handling POST
requests -- a very common case when comments plugin is used. This is
the same problem described in SF.net bug #1184799 [2], just experienced
with different HTTP server -- bozohttpd instead of Twisted.
