Goodreads Sync - PROXY_TYPE_HTTP_NO_TUNNEL error on MacOS

[Mdejonge]

When I want to configure Goodreads sync I get the following error message:

Tried to uninstall and install the plugin but without any succes.

I don't have a MacOS machine to offer any comment on whether this plugin does actually work on that OS. I suggest you ask in the MobileRead forum plugin thread to see if any other Max users out there.

A fix is on the way 😁

For reference for anyone that later visits this issue (or myself with goldfish memory) - I have not accepted the PR above as it is too bespoke and I don't want to have to support it, thanks @GwynethLlewelyn for taking a stab at it anyway. If you are desperate for a version on MacOS that works around this issue, I am told his branch is currently working so feel free to create your own personal use build from it.

The long term fix will be to use a later version of the httplib2 library, however this is blocked currently because calibre 7.x uses an older python version than what httplib2 requires. When calibre 8.x is released it is possible Kovid will have updated his bundled python libraries with calibre and then it might be possible to upgrade httplib2 without plugin specific patches to it.
