mitmproxy-2.7 is not working, due to netlib version mismatch

[th-macports@…]

After doing a port upgrade, mitmproxy-2.7 now complains:

$ mitmproxy-2.7
Traceback (most recent call last):

Of course, activating the old netlib port will solve this for now.

In the future, please use WikiFormatting, fill in the Port field with the actual name of the port and Cc the port maintainers (port info --maintainers py27-mitmproxy), if any.

py-netlib was updated in r146178, and probably updating py-mitmproxy as well should solve this issue. #50611 is requesting the update.

[petrrr]

py-mitmproxy pins the version to exactly the same minor version as py-netlib (see ​https://github.com/mitmproxy/mitmproxy/blob/v0.15/setup.py#L17), so we would need to update to 0.16. Ticket #50611, provides only an update to 0.15, which will not solve this problem. At the same time the tar.gz tarball for version 0.16 is not published on PyPI, which is currently used by this port.

So either, we

1. use the tarball from GitHub,
2. try to use the wheel file on PyPI,
3. wait until netlib and mitmproxy merge (expected to happen for version > 0.16)

I filed this ​issue understand better, why the tar.gz file is no longer available on PyPI and what to expect in future.

r147514 updates mitmproxy to 0.16 and should fix this issue.
