cherrypy + ssl + pyinstaller

[harsh savla]

I am trying to get cherrypy to work with ssl support.

Env:

build: debian wheezy 64-bit chroot

run:   debian wheezy 64-bit chroot

cherrypy: 4.0.0

python: 2.7.10 (has ssl support, can import ssl)

pyinstaller: 2.1

Here is the code:

sss.py

import cherrypy

config = {
'global' : {
'server.socket_host' : '0.0.0.0',
'server.socket_port' : 8888,
'server.thread_pool' : 8,
'server.ssl_module' : 'builtin',
'server.ssl_certificate' : '/certs/cert.pem',
#'server.ssl_certificate_chain' : '/path/to/certs/ssl123_ca_bundle.pem',
'server.ssl_private_key' : '/certs/key.pem'
}
}

class App:

    @cherrypy.expose
    def index(self):
        return 'Is this secure?'

if name == 'main':
    cherrypy.quickstart(App(), '/', config)

I compile the above code with: pyinstaller sss.py and run the resultant binary on a 64-bit chroot environment (which is same as build env)

I see the following traceback.

Has anyone encountered issues with pyinstaller + cherrypy + ssl?

PS: Filed an issue on the cherrypy project https://github.com/cherrypy/cherrypy/issues/1448

Start removing stuff until it works: chroot, chroot's custom python, pyinstaller, etc. This is not likely a problem with cherrypy. I've never used pyinstaller, but have used py2exe, and haven't had import errors within cherrypy. That said, I had ssl turned off at the time.

ssl_builtin is in cherrypy.wsgiserver, so I'd double check that 1) your pythonpath is set correctly for the chroot, 2) that you're importing the correct cherrypy (and not an old system package version) and 3) that you're using the python executable you're intending to. It sounds like you're importing the wrong cherrypy, or using the wrong python executable.

Hi Joseph,

Thanks for your reply. You are right, it was not a cherrypy issue.

Jason Coombds, one of the lead members of the project pointed me to the solution. Here is the link: https://github.com/cherrypy/cherrypy/issues/1448

tl;dr

pyinstaller did not recognize the module 'cherrypy.wsgiserver.ssl_builtin' since it was being loaded programatically. I had to pass --hidden-import=cherrypy.wsgiserver.ssl_builtin and it worked after that.
