Errors when behind my proxy at work about walkaround

[GoogleCodeExporter]

Can you take a look at your browser's JavaScript console to see if it shows any 
other errors?  For example, any scripts or other resources that fail to load?

Sure. In Firefox, I get a number of warnings along the lines of:

Warning: Unknown property 'transition'.  Declaration dropped.
Source File: https://inevowalk.appspot.com/wave?id=ZQl66xZ9sUbiw-S2
Line: 43


and I get one error, on the wave index page:

Error: downloadable font: download failed (font-family: "Open Sans" 
style:normal weight:normal stretch:normal src index:2): status=2152398920
source:

Line: 0
Source Code:

RxqtaUH3T8E0i7KZn-EPnyo3HZu7kw.woff") format("woff"); }




With Chrome, it's different. I get no warnings, and one error on the individual 
wave:

Error: Failed to load resource - 
https://talkgadget.google.com/talkgadget/channel.js




I can't tell you at this point if I get those errors on other networks.

Thanks.

The message "Error: Failed to load resource - 
https://talkgadget.google.com/talkgadget/channel.js" is very suspicious.  Is 
your proxy blocking the download of this file?

Looks like it. I can't seem to reach the Google Talk gadget itself, either.

Though Firefox doesn't throw that same error in Walkaround, when I try to 
access that file directly (or the Google Talk gadget in general), I get errors 
in both browsers:



In Chrome:

Error 111 (net::ERR_TUNNEL_CONNECTION_FAILED): Unknown error.



In Firefox:

The proxy server is refusing connections
Firefox is configured to use a proxy server that is refusing connections.
  Check the proxy settings to make sure that they are correct.
  Contact your network administrator to make sure the proxy server is
    working.



So I guess the question is - how important is that file to Walkaround? Could we 
remove the reference from our installation without issue? Or could we copy the 
file to another server and point Walkaround to there instead?

Or is this file so intrinsically linked to Walkaround that I just won't be able 
to use it from work behind this proxy?

The file is part of App Engine's Channel API.  Without it, you won't be able to 
see live edits from other users.

The quickest solution would be to ask your proxy administrator not to block 
that file.

We could also implement a workaround by having the walkaround server fetch the 
file from talkgadget.google.com and serve it to the browser rather than 
redirecting the browser.

(Another alternative would be to fall back to polling for updates every few 
seconds, but that makes live collaboration less smooth.)

It's probably not worth implementing an across-the-board fix for something that 
may just be affecting me.

Is the code that fetches it in Walkabout, or in App Engine? If it's in 
Walkabout, can you point me to its location? I'll see about doing a quick hack 
for the one server I need it on, so that it fetches the file from another 
location that I copy the file to.

I'll see about the proxy server change, but I can't do that until January 
anyways as the IT department is on a skeleton crew for the holidays. Not sure 
if they'd do it anyways.

Thanks for all your help,

Graham

http://code.google.com/p/walkaround/source/browse/src/com/google/walkaround/wave
/server/WalkaroundServerModule.java#210

  @Provides @Named("channel api url")
  String provideChannelApiUrl() {
    return "/_ah/channel/jsapi";
  }

You should be able to change this to https://example.com/channel.js (if that is 
where you put the file).  http might work as well but it will lead to 
mixed-content warnings.

Thanks for your help. I've now solved my problem, but in a bit of a different 
way, so I didn't have to go messing with my code.

I save a copy of the channel.js file to my local machine, and then added a line 
to my HOSTS file

file://c:/WaveFix/channel.js     
https://talkgadget.google.com/talkgadget/channel.js

So it just grabs the file locally for me, while leaving everyone else working 
normally.

Thanks again for your help, though. I couldn't have found the issue without it, 
and I hope having this thread here might help anyone else with the same issue.

I'm glad you got it working.  Thanks for reporting your solution here.

I'll mark this as WontFix since no code changes in walkaround are needed.
