[gwt-contrib] Building Elemental fails

[Jens]

I just tried to add Elemental to our GWT trunk builds and thus changed "ant 
clean dist" to "ant clean elemental dist" and now always getting the 
following build error:


generate:
 [exec] Traceback (most recent call last):
 [exec]   File "idl/scripts/elemental_fremontcutbuilder.py", line 217, 
in 
 [exec] sys.exit(main())

line 279, in Generate

mixins)

line 188, in GetInterface
 [exec] raise RuntimeError('Interface %s is not loaded' % 
interface_name)
 [exec] RuntimeError: Interface ElementalMixinBase is not loaded


The build is executed by Jenkins on Ubuntu 12.04 with Python 2.7.3. I tried 
the same on Mac OS (without Jenkins) and everything works as expected. I 
have also created MD5 sums of WebKitCSSRegionRule.idl on Ubuntu and Mac OS 
and both MD5 sums are the same.

Does anyone have an idea what can cause the above error?

I can't reproduce this, we're also running ant clean elemental dist on our 
teamcity build. We're also running ubuntu 12, python 2.7.3. Last confirmed 
building as of 0d6a865556ca56840114e8397a1f2be522e83361 (current HEAD).

Thx for checking it, Colin. 

Pretty strange that it doesn't work. The error also happens if I just 
execute ant on console directly on the server.

Good thought, I tried that too to confirm that teamcity wasn't setting 
anything funny. Still passed, not sure what is up.

[gwt-contrib] Re: Next GWT Contributor Hangout

[Joshb]

Hi Bhaskar,

I am a long time GWT user (5+ years), and am very much interested in the 
developments surrounding SDM for the 3.0 release.  I know there has been a 
lot of talk about how the debug environment will look, and was hoping 
someone from google's GWT team could speak to what the goal is for GWT 3. 
 I came across these two videos:

http://www.youtube.com/watch?v=EbRviM8HgBs is a demo of how DART+Eclipse 
debugging works, and is exactly how I would hope a GWT implementation would 
go.  The video is by Seth Ladd, and if memory serves, he was on the GWT 
team at some point.  It looks like the solution uses Source Maps, and from 
my (limited) understanding, I would think that there are enough 
similarities between what is going on that something similar should work 
for GWT.  

http://www.youtube.com/watch?v=_uzSw_fb7NQ is a more generic 
Javscript-Eclipse debugging example.

I apologize if this isn't the right forum for this type of request/message, 
but as always, I will be following the hangout to see how things are 
progressing.

Thanks,

Josh
