Greetings, Alexandre!

Thank you very much for cyclone! It is really cool!

thanks!

But i have a trouble and a note:)

[Trouble] Making cyclone-sse project (https://github.com/FZambia/cyclone-sse) i came across a problem - can not install cyclone on CentOS 5. This is because their is no OpenSSL 0.9.8f distribution. Here detail description http://stackoverflow.com/questions/7340784/easy-install-pyopenssl-error
In my project i avoided this problem by adding OS version check in setup.py and using pyopenssl==0.12 in case of Centos 5.

try:

to avoid installation problems on centos 5

which has no distributions for OpenSSL 0.9.8f

from distutils.version import StrictVersion
import platform
os, version, _type = platform.linux_distribution()
if os == "CentOS" and StrictVersion(version) < StrictVersion('6.0'):
requires.insert(0, "pyopenssl==0.12")
except:
pass

i guess it requires a patch in cyclone's setup.py to support centos 5
currently, i have no centos (and time :p) to test, thus, i appreciate if you can make the change and send a pull request

But standalone cyclone still can not be installed

i believe the above would fix it as well

[Note] While installing i got following warning:
package init file 'twisted/plugins/init.py' not found (or not a regular file)
*** Failed to update Twisted plugin cache. ***

this might be because twisted is not installed, or is installed in a different location (most likely)
does it show "cyclone" in the list of commands when you run twistd?

Thanks for your time!

just found this SO post: http://stackoverflow.com/a/7525163
According to it:

Related: keep in mind that in your project, you must not have a file twisted/plugins/init.py. If you see this warning during installation:

package init file 'twisted/plugins/__init__.py' not found (or not a regular file)

it is completely normal and you should not try to fix it by adding an init.py.

So i think there is probably nothing wrong with this warning.

I'll try to make a setup.py patch for centos 5 as soon as i find some time! Thanks!

import sys
import platform
from distutils import log
from distutils.core import setup
from distutils.version import StrictVersion


requires = ["twisted"] 


pyopenssl = "pyopenssl"
# avoiding installation problems on old RedHat distributions (ex. CentOS 5)
# http://stackoverflow.com/questions/7340784/easy-install-pyopenssl-error
py_version = platform.python_version()
if StrictVersion(py_version) < StrictVersion('2.6'):
    distname, version, _id = platform.dist()
else:
    distname, version, _id = platform.linux_distribution()
is_redhat = distname in ["CentOS", "redhat"]
if is_redhat and version and StrictVersion(version) < StrictVersion('6.0'):
    pyopenssl = "pyopenssl==0.12"

requires.append(pyopenssl)


# PyPy and setuptools don't get along too well, yet.
if sys.subversion[0].lower().startswith('pypy'):
    from distutils.core import setup
    extra = dict(requires=requires)
else:
    from setuptools import setup
    extra = dict(install_requires=requires)


setup(
    name="cyclone",
    version="1.0-rc12",
    author="fiorix",
    author_email="[email protected]",
    url="http://cyclone.io/",

    keywords="python non-blocking web server twisted facebook tornado",
    packages=["cyclone", "twisted.plugins"],
    package_data={"cyclone": ["appskel.zip"],
                  "twisted": ["plugins/cyclone_plugin.py"]},
    **extra
)

try:
    from twisted.plugin import IPlugin, getPlugins
    list(getPlugins(IPlugin))
except:
    log.warn("*** Failed to update Twisted plugin cache. ***")

With such setup.py cyclone can be successfully installed on CentOS 5, but I can not check how SSL parts of cyclone work when 0.12 version of pyopenssl installed. Anyway i think this is much better than nothing.
