Not specify host and port in `frontend` definition

[dbclkh]

Hi,

I'm having a small problem with my pyhaproxy script, and I'm hoping that you can lead me in the correct direction.

My haproxy.cfg contains two frontends...

frontend http
    bind 0.0.0.0:80
    acl test_site1 hdr(host) -i test_site1.local
    use_backend test_site1_back if test_site1
    etc. etc.

frontend https
    bind 0.0.0.0:443 ssl crt /etc/ssl/private
    option forwardfor
    reqadd X-Forwarded-Proto:\ https
    acl test_site1 hdr(host) -i test_site1.local
    use_backend test_site1_back if test_site1
    etc. etc.

The haproxy works just fine - no problem there.

Part of my clean up script looks like this:

haproxy_cfg = '/etc/haproxy.cfg'
haproxy_bak = '/etc/haproxy.bak'

parser = Parser(haproxy_cfg)
configuration = parser.build_configuration()
frontends = configuration.frontends
backends = configuration.backends

It gives the following error message: [line 287 is configuration = parser.build_configuration()]

Traceback (most recent call last): File "./cleaner.py", line 287, in configuration = parser.build_configuration() File "/blarblarblar-manyfolders/python2.7/site-packages/pyhaproxy/parse.py", line 41, in build_configuration self.build_frontend(section_node)) File "/blarblarblar-manyfolders/python2.7/site-packages/pyhaproxy/parse.py", line 203, in build_frontend 'Not specify host and port in frontend definition') Exception: Not specify host and port in frontend definition Segmentation fault

What am I doing wrong or missing?

Thanks for your issue. I can not reproduce the error using your frontend configurations via the following code. Could you please run nosetests -sv to take a test in your local environment and see the results, as well as your pyhaproxy version?

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import pyhaproxy.parse as parse

class TestParse(object):

    @classmethod
    def setup_class(cls):
        pass

    @classmethod
    def teardown_class(cls):
        pass

    def setup(self):
        filestring = r"""
frontend http
    bind 0.0.0.0:80
    acl test_site1 hdr(host) -i test_site1.local
    use_backend test_site1_back if test_site1

frontend https
    bind 0.0.0.0:443 ssl crt /etc/ssl/private
    option forwardfor
    reqadd X-Forwarded-Proto:\ https
    acl test_site1 hdr(host) -i test_site1.local
    use_backend test_site1_back if test_site1

"""
        self.parser = parse.Parser(filestring=filestring)
        self.configration = self.parser.build_configuration()

    def teardown(self):
        pass

    def test_parse_frontend_section(self):
        for frontend in self.configration.frontends:
            print '-' * 15
            print frontend.name, frontend.host, frontend.port
            for acl in frontend.acls():
                print acl

Hi Joey,

The version I'm using is 1.7.5-2 2017/05/17. I'll have a look at the nosetests and then get back to you.

Hi Joey,

larshansen@<comp-name> Downloads $ python3 /usr/local/bin/nosetests -sv --all-modules testpyha.py
testpyha.TestParse.test_parse_frontend_section ... ---------------
http 0.0.0.0 80
<acl_line: acl test_site1 hdr(host) -i test_site1.local>
---------------
https 0.0.0.0 443
<acl_line: acl test_site1 hdr(host) -i test_site1.local>
ok

----------------------------------------------------------------------
Ran 1 test in 0.002s

OK

That seems okay to me?

Hi, yes and the passed test means that the two frontend sections could be parsed correctly. Would you mind providing all the configurations? Thanks.

BTW: I noticed that the python verions is 3. While to be honest, this library has not been well tested in Python 3 yet. Could you please run it in Python 2 and see the results instead? Apologize for the inconvenience.

Hi Joey, I've tested it on another machine here at my company - it works fine there. It must be something on the first machine then.

So glad to hear that. 😄
