Re: [google-appengine] Cron and App Versions
The cron jobs are uploaded separate from the source code. I think there is only one version of cron jobs, the last one uploaded. If you switch default application you only switch source code. 2010/10/7 Remigius : > In the documentation of cron jobs (see > http://code.google.com/intl/de-CH/appengine/docs/java/config/cron.html#Cron_and_App_Versions) > it says that "Cron requests are always sent to the default version of > the application." > > This may be correct, but is a very short statement of what actually > happens, leaving imho some questions unanswered.

[google-appengine] Cron and App Versions
In the documentation of cron jobs (see http://code.google.com/intl/de-CH/appengine/docs/java/config/cron.html#Cron_and_App_Versions) it says that "Cron requests are always sent to the default version of the application." This may be correct, but is a very short statement of what actually happens, leaving imho some questions unanswered. We have uploaded a new version of an app, which was the first version that contained a cron.xml. Therefore we saw only an error in the log saying "No handlers matched this URL.". After some thinking, we came to the obvious conclusion that cron jobs go to the default version (see above). So far, so good. But what happens now of there are several versions of cron.xml deployed with different app versions? Is each of the cron jobs of possibly multiple versions executed? Or is cron.xml a singleton? Does it make sense to execute cron.xml from other versions than the default version (in our case it did not do any harm, as the handler was not present, but this may well happen in other cases)? At least I would appreciate to see some documentation about which cron.xml is/are active at a given time, to be able to exercise the necessary control over cron.xml deployment. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Cron and app versions
Hi, when using cron in an app with multiple versions, shouldn't the cron job run on the version that has the cron.yaml? It seems that currently the cron job is run on the default version. I changed the version in the admin console using the dropdown box but my cron jobs (that are only in the latest version) are still displayed. The cron job itself is marked as "failed" while a manual GET using a browser to the versioned address does not result in an error. The cron requests show up as 404 errors in the request logs of the default version. Bug?
