Add Windows support

[jezdez]

This is related to the things we discussed at PyCon

[benoitc]

wip. planned for R18.

[benoitc]

Some update on that:

• SOCKET support is quite done, a branch will be posted online next week

TODO:

handle service start/stop/restart to use gunicorn as a full windows service. It is replacing somehow the use of signals under unix.

[benoitc]

the support will finally happen in R20. i will create the new PR to track the development of this feature next week.

Things to fix are:

• adapt Worker notifications to windows
• port the signaling to windows: reload and reexec
• make sure sockets can be inherited among processes

What is the progress on adding windows support for gunicorn?. Or rather How far are you from R20? I am having the same problem as #587

[benoitc]

Slow progress. I want to release R19 with the threaded work now. I will push a version on monday. the windows support will arrive right after.

[helmus]

Is this windows supported version available somewhere ?

[renierdbruyn]

Windows support will be in R20, so I guess it will be a while till guincorn will have windows support... I created a vm with Ubuntu, and this works for me.....

Just curious as to any progress in this. As a first pass it doesn't even need to be fast; a big advantage will be just being able to develop with Gunicorn on Windows and push to a Linux server (e.g. Heroku) without changing config.

@robertlagrant it's on my todo. I need to find a windows license first. R20 will be released in october,
