pub-dartlang server crashes when behind a proxy/firewall

[DartBot]

From hulibu...@googlemail.com on July 01, 2014 20:55:28

What steps will reproduce the problem? 1. Have a machine behind a firewall using a proxy
2. setup and start pub server as described at https://github.com/dart-lang/pub-dartlang What is the expected output? What do you see instead? I would expect the server to start and work at least within the LAN.

What happens instead is the following:

API server and module are still running, but the admin server seems to just crash and there is nothing listening on 8080. What version of the product are you using? On what operating system? Ubuntu server 14.04 x64
Google app engine 1.9.6 - 2014-06-03
Python 2.7.6 Please provide any additional information below. It works perfectly fine when the machine has direct access to the internet without using a proxy. Why does the server connect to the internet anyway?

btw:

env variables

$http_proxy
$https_proxy
$HTTP_PROXY
$HTTPS_PROXY

are set correctly but are ignored bei the publang server

This sounds like an issue with appengine's infrastructure, not pub.dartlang.org in particular. I don't think there's anything we'll be able to do about it.

This issue is not regarding the pub.dartlang.org instance but about running your own Pub instance behind a firewall.
