Problem with py2exe-frozen CGIHttpServer-based script

[vincent wehren]

Hi,

as a small capabilities demo I coded the piece below to show how to use
Python for cgi'ing on localhost and it more or less does the trick :-).
However, I when I freeze it with py2exe, starting the resulting exe fires up
the server allright,
but fails execute cgi commands correctly (i.e. the expected output - let's
say from cgi.test()) - is no longer emitted to the browser...).

Is there some py2exe-magic I need to do that I don't know of? Something in
the code that prevents the frozen version to work?


Any pointers would be much appreciated...

Python 2.3.2 , Py2exe 0.4.2, Win XP

Here's the code...:


import CGIHTTPServer, BaseHTTPServer, SimpleHTTPServe r
import threading
import sys

port=8000

# nicked from the SimpleHTTPServe r test rig
def simple( HandlerClass = SimpleHTTPServe r.SimpleHTTPReq uestHandler
,ServerClass = BaseHTTPServer. HTTPServer):
"""
"""

base(HandlerCla ss, ServerClass)


# nicked from the BaseHTTPServer test rig
def base(HandlerCla ss = BaseHTTPServer. BaseHTTPRequest Handler,
ServerClass = BaseHTTPServer. HTTPServer, protocol="HTTP/1.0"):
"""
"""

server_address = ('localhost', port)
HandlerClass.pr otocol_version = protocol
try:
httpd = ServerClass(ser ver_address, HandlerClass)
sa = httpd.socket.ge tsockname()
print "Serving HTTP on", sa[0], "port", sa[1], "..."
httpd.serve_for ever()
except KeyboardInterru pt:
http.socket.clo se()



def RunServer(ready Event=None
,HandlerClass = CGIHTTPServer.C GIHTTPRequestHa ndler
,ServerClass = BaseHTTPServer. HTTPServer):

simple(HandlerC lass, ServerClass)
if readyEvent:
readyEvent.set( )

def main():

testServerReady = threading.Event ()
threading.Threa d(target=RunSer ver, args=(testServe rReady,)).start ()
testServerReady .wait()


if __name__ == '__main__':
main()

That's an easy one!
Look into CGIHTTPServer.p y, near line 232:
if self.is_python( scriptfile):
=> interp = sys.executable
if interp.lower(). endswith("w.exe "):
# On Windows, use python.exe, not pythonw.exe
interp = interp[:-5] + interp[-4:]
cmdline = "%s -u %s" % (interp, cmdline)

It tries to start 'sys.executable ' with the python cgi script. Normally
sys.executable is the Python interpreter, but for a py2exe'd script this
is the running executable (which is no longer a usual Python
interpreter).

Changing this line to 'interp = r"c:\python23\p ython.exe"' makes the
frozen script work (although then the Python installation is required
again).

(A few minutes later, looking at CGIHTTPServer.p y again)
It seems you have to hack this module so that the code block starting at
line 270 is used, which says:
else:
# Other O.S. -- execute script in this process
and then it works fine.

Re: Problem with py2exe-frozen CGIHttpServer-based script

Look at this piece of code in my *modified* CGIHTTPServer.p y:

if self.is_python( scriptfile):
# THIS DOESN'T WORK AFTER PY2EXE!
#interp = sys.executable
#if interp.lower(). endswith("w.exe "):
# # On Windows, use python.exe, not pythonw.exe
# interp = interp[:-5] + interp[-4:]
#cmdline = "%s -u %s" % (interp, cmdline)
cmdline = "%s -u %s" % ('distpython', cmdline)

The comments have the "original" standard library code. It uses
sys.executable, and that returns "yourCGIProg.ex e" instead of
"Python.exe " or something like that, as you need for running the CGI
program.

My *modified* version works when used by some *.exe generated by
py2exe.

Hi Thomas,

I suspected something along those lines....

I'll give the hack a go!

Thanks!
