Originally in https://code.google.com/p/dart/issues/detail?id=18847

Unfortunately, with the continuous build of May 22, our application does not work anymore (Dartium reports errors and does not start). Is there a bit more stable version available with that fix?

Can you be a little more specific about what error is being reported.

Added NeedsInfo label.

I don't know.
I hope that user from https://code.google.com/p/dart/issues/detail?id=18847 will provide more information.

Hi,

I use Dart from my company's network with proxy.

When I start Dartium (Dart SDK version 1.5.0-edge.36468), then I get the error:

--- 08:58:09 Starting pub serve : hanalite-admin ---
Loading source assets... (1.6s)
Loading smoke/src/default_transformer transformers... (1.0s)
Transformer library "package:smoke/src/default_transformer.dart" not found.

In older version, pub serve was not called.
Why is pub serve called with the new version?

Best regards, Anja

I think the issue is that pub serve does not work with proxies.
(we are using Windows as OS)

When I start Dartium from a network without proxies, this error does not appear, but other errors. I will open an extra bug for this.

When loading transformers, "pub serve" starts a server on localhost and starts an isolate that loads its sources from that server. All the HTTP requests go through the VM, so if there's special configuration that needs to happen to make it work with proxies that's where it should go. If your proxy forbids any localhost connections, though, there may not be a solution until issue #16368 is fixed.

Bob, are you guys using "localhost" or "127.0.0.1" to connect locally to pub? In the past I have experienced issues where the latter would work in places where the name localhost wouldn't.

We use "localhost" for "pub serve" and "127.0.0.1" for "pub build".

Anja: if you run "pub serve --hostname 127.0.0.1", does it work?

In my environment variables, I have set

http_proxy proxy.wdf.sap.corp:8080
https_proxy proxy.wdf.sap.corp:8080

Otherwise, pub get would not work.

With this settings, "pub serve --hostname 127.0.0.1" does not work:

Hi Anja,

It appears that your proxy intercepts localhost connections. They may need to be explicitly allowed.

Can you try adding the following to your existing environment:

  no_proxy localhost,127.0.0.1,::1

Thanks!,

Hi Anders,
The error is now gone by setting no_proxy localhost,127.0.0.1,::1
Thanks a lot, Anja

Great to hear it is now working. For a bit of background see issue #15215, where we considered automatically adding the loopback addresses to 'no_proxy', but due to the behavior of wget and curl put that on hold.
