As one might suppose, the code is in dspace-xmlui. Specifically it is in
org.dspace.app.xmlui.aspect.artifactbrowser.CommunityBrowser. The value of
xmlui.community-list.cache is passed to
org.dspace.app.xmlui.util.DSpaceValidity.setAssumedValidityDelay, where it
is parsed:
* This method takes a string which is parsed for the delay time, the
string
* must be of the following form: "<integer> <scale>" where scale is
days,
* hours, minutes, or seconds.
*
* Examples: "1 day" or "12 hours" or "1 hour" or "30 minutes"
The code does accept either singular or plural and doesn't care if this
matches the number -- "1 days" or "33 minute" will be accepted. The unit
of measure is required.
It appears that, if unconfigured, the cache validity period is zero: the
underlying objects will always be checked for changes. The numeric value
is not checked in any way, so long as it is indeed a Java long integer, so
you could set it to zero if you wish, but I think that will have the same
effect as leaving it unconfigured.
