user/yawning/obfsproxy, branch bug11558

Change zope usage to deal with really old zope.

2014-04-22T21:02:09+00:00

Debian squeeze packages zope.interface-3.5.3, which is utterly
prehistoric and was puking on the `@implementer` decorator.  Fixing
this makes the code work, though txsocksx also has a dependency on
"zope.interface that isn't from 2009".

Add compatibility code for old versions of Twisted.

2014-04-19T05:09:20+00:00

Recent changes has broken obfsproxy on systems running Twisted < 13.2.0.
We now monkeypatch Twisted from __init__.py if the new features we are
expected are missing.

Things added:

 * twisted.internet.error.UnsupportedAddressFamily - Just a
   `Exception`, 100% compatible with Twisted.

 * twisted.internet.endpoints.HostnameEndpoint - The older the copy of
   Twisted is, the bigger the difference between the real
   implementation.

    * IPv4 will always work.
    * IPv6 will work for Twisted >= 12.2.0.
    * Hostname (DNS resolution) will never work.

  The limitations here are ok, since the endpoint in question is used
  when tunneling obfsproxy traffic through another proxy, and tor will
  configure that via IP address.

This fixes bug #11558.

	ChangeLog

Tweak the proxy logging a bit.

2014-04-16T13:10:13+00:00

Clean some long lines, and some instances of pylint's
logging-not-lazy (although the rest of the codebase has many more
instances of this).

Clean up error handling when the http proxy doesn't return status.

2014-04-16T08:41:42+00:00

Some HTTP proxys opt to close the connection instead of returning a
HTTP status code on certain failures (Eg: polipo auth faliure, privoxy
ACL denial).  This change logs a better error message to the obfsproxy
log when that happens.

As an added bonus the SOCKS5 server now knows about EHOSTUNREACH, so
a more informative response is sent on that failure type.

Don't feed None to parseProxyURI() in external mode.

2014-04-15T12:44:51+00:00

Add support for connecting via a HTTPS CONNECT proxy.

2014-04-15T10:00:21+00:00

This adds a HTTPS CONNECT client.  It's been lightly tested with both
privoxy and apache2 and appears to work, both without authentication
and with Basic.

Fix connecting via a SOCKS proxy.

Add ChangeLog entry for #11190.

2014-04-13T11:27:05+00:00

Changed the obfsproxy shebang to point to `python2`

2014-04-13T11:21:58+00:00

On all the systems I've checked so far running a U*IX variant,
`python2` is a valid symlink to the Python 2.x.x interpreter.  Since
certain systems are also shipping Python 3 and some make it the default
system python, the shebang should be explicit.

This fixes bug #11190.
