Re: Re-deployment on appengine sometimes breaks GWT app (Module.Cache.html not found)

Yes, changing the version is the best way. GAE seems to fail its uploads fairly 
regularly in my experience. Just use a build number along with your version, 
upload, smoke test to verify it is working, and then mark as current version in 
the GAE console.

Today it happened again.

   - It definitely is NOT the browser cache.
   - I redeployed various times, without success.
   - From the appengine console I deleted the active instance without 
   success.

Then finally I incremented the version (appengine-web-app.xml), redeployed 
and switched the versions manually in the appengine console. - Does one 
have to change the version to ensure a successful switch?

I wish - I cleared the cache and tried different browsers to no avail.
2.) Maybe AppEngine distributes your app across different nodes which 
may take a while and you hit a node that is not updated yet (load 
balancing issue).
Yes that was my thought too, it looks like an appengine issue, but how 
do you 'prove' that? - it's so spurious.

Re-deployment on appengine sometimes breaks GWT app (Module.Cache.html not found)

2013-04-08 Thread Robert Hoffmann
Hi,

Every now and then when uploading an update of my GWT application to 
appengine, the uploaded app seems in an inconsistent state, i.e. the 
Module.Cache.html file is not found. 

e.g. App not working, Browser console says 
'/Module/C96DE337B74EEDDBD2CF70FC4C65827B.cache.html not found'

This is scary, since I never know if an update will break my site. 

Workaround: Typically, if I deploy again immediately, it will work. But 
meanwhile the site is not working. 

Has anyone every had this problem? Any ideas as to what could go wrong?

Many thanks
