Re: [Exist-open] Updating autodeployed xar

[Jens Ø. P. <oe...@gm...>]

Hi,

The AutoDeploymentTrigger ($EXIST_HOME/src/org/exist/repo/AutoDeploymentTrigger.java) "Installs any application which does not yet exist in the database," so the behaviour you have is to be expected. See also conf.xml:

<!-- 
             ! AutoDeploymentTrigger will install any .xar application package it finds
             ! in the autodeploy directory unless the application has already been installed
             ! in the db. --> 

On line 78 of the AutoDeploymentTrigger.java, however, someone seems to have thought about your (very valid) use case, but only in a TODO about checking version numbers.

Unless version numbers are checked, there will be no way of upgrading apps - the xars in autodeploy from the initial installation would overwrite any new installs upon restart. The problem is, I guess, that there is no generally recognised numbering scheme for xar app versions.

That part I have down, thanks to earlier entries to this list. My problem is that I have made an app in eXide and chosen download/application. This gives me a xar-file. My config management (CM) agent puts this file in the autodeploy dir, and eXist then installs in when started. So far so good. Now I make some changes to my app on my development machine, change the version number in expath-pkg.xml, download the new xar, distribute that with CM and restart eXist. Unfortunately the changes don't get deployed. The old version of the app still exists in the database. Is there a trick to rolling out new versions of xar-files?
