Today I want to port lighttpd on another platform which basically a debian sarge system but without perl and dpkg package system on it. Since it's a debian based platform so I start from porting debian's binary lighttpd package, however I've found there're some perl script lays in /usr/share/lighttpd which are used when lighttpd startup.
While I can easily dump the result of perl script into a textfile,
and then startup my lighttpd correctly, I thought "maybe port it to python is not a bad idea." (since my target platform has python!), so here is the effort:
create-mime.assign.py
#!/usr/bin/python
#
# This script directly translate from debian's lighttpd perl script:
# create-mime.assign.pl

import sys
try:
f = open("/etc/mime.types",'r')
extensions = {}
print "mimetype.assign = ("
for line in f:
line = line.strip()
if line.startswith('#'): continue
if line != "":
splitlist = line.split()
if len(splitlist) < 2: continue
mime = splitlist[0]
for ext in splitlist[1:]:
if ext in extensions.keys(): continue
extensions[ext] = 1
print '".%s" => "%s",' % (ext,mime)
f.close()
print ")"
except Exception,e:
print e
sys.exit(1)
include-conf-enabled.py
#!/usr/bin/python
#
# This script directly translate from debian's lighttpd perl script:
# include-conf-enabled.pl
#

#
import os,glob
confdir = "/etc/lighttpd/"
enabled = "conf-enabled/*.conf"
os.chdir(confdir)
for file in sorted(glob.glob(enabled)):
print 'include "%s"' % file
use-ipv6.py
#!/usr/bin/python
#
# This script directly translate from ubuntu's lighttpd perl script:
# use-ipv6.pl
#
# Author: timchen119.at.nospam.gmail.com

#
import socket
##this sometimes not accurate. (like in vserver mode)
#if socket.has_ipv6:
#
try:
if socket.socket(socket.AF_INET6,socket.SOCK_STREAM,0):
print 'server.use-ipv6 = "enable"'
except:
pass
All of these files can be found in
http://kalug.linux.org.tw/~tim/lighttpd-debian-python-script/Well something quite interesting happened when I port the debian's create-mime.assign.pl into python, It's that my python script's final result is not equivalent to perl one and has more mime types than its :

So I start to dig why this happened, and I've found a strange perl regex filter all these mimetypes out, I believe it's a minor bug in original perl program. (or it does implicitly doing something meaningful? well I can't figure it out.)

just copy these py scripts to /usr/share/lighttpd
and change these lines if you're using debian based system
