Class JiraVCacheRequestContextSupplier

java.lang.Object

com.atlassian.jira.cache.JiraVCacheRequestContextSupplier

All Implemented Interfaces:

java.util.function.Supplier<com.atlassian.vcache.internal.RequestContext>

@ParametersAreNonnullByDefault
public class JiraVCacheRequestContextSupplier
extends Object
implements java.util.function.Supplier<com.atlassian.vcache.internal.RequestContext>

Lenient request context supplier that may create request context for a thread if it hasn't been created. Normally in Cloud Vertigo context is initialised at the beginning of the request with a tenant that comes in request, therefore it is not allowed to call components that are tenant aware without request context. However, Server instance is always tenanted and sometimes components that use vcache are called from threads that do not have context initialised (e.g. in constructor during container initialisation); Since this behaviour is allowed in Jira Server 7.x we will just log it as a warning and create NoopRequestContext that will always compute value or return empty value.

Since:

v7.1
