[Building Sakai] update ehcahce to 1.5.0?

Hi All,
At the moment we are using ehcache 1.3.0. The latest release is 1.7.0: http://ehcache.org/changes-report.html It seems that we can straightforwardly upgrade to 1.5.0 9 9 (there seem to be API changes in 1.6.0 that break the memory service) thoughts?

IMHO, I would certainly go up to 1.5 but I would be very tempted to do the work in memory service to make it work with 1.6. You should not have to change anything in the API only the implementation so the scope will be limited to just memory service impl. If that is not the case, then there is something really very wrong with the API. I will be updating K2 as "This release introduces a new high performance cache core, which is two orders of magnitude faster." in the 1.6 release is quite compelling Ian > > D > > _______________________________________________ > sakai-dev mailing list > sakai-dev@... > http://collab.sakaiproject.org/mailman/listinfo/sakai-dev > > TO UNSUBSCRIBE: send email to sakai-dev-unsubscribe@... > with a subject of "unsubscribe" _______________________________________________ sakai-dev mailing list sakai-dev@... http://collab.sakaiproject.org/mailman/listinfo/sakai-dev TO UNSUBSCRIBE: send email to sakai-dev-unsubscribe@... with a subject of "unsubscribe" |

I'll see about cleaning them up the only mystery one is: /home/dhorwitz/sakai/kernel-trunk/kernel-impl/src/main/java/org/sakaiproject/content/impl/serialize/impl/conversion/SAXSerializableResourceAccess.java:[56,43] package edu.emory.mathcs.backport.java.util does not exist Though no doubt that is findable too :-) D > I will be updating K2 as > "This release introduces a new high performance cache core, which is > two orders of magnitude faster." in the 1.6 release is quite compelling > > Ian > > >> >> D >> >> _______________________________________________ >> sakai-dev mailing list >> sakai-dev@... >> http://collab.sakaiproject.org/mailman/listinfo/sakai-dev >> >> TO UNSUBSCRIBE: send email to >> sakai-dev-unsubscribe@... with a subject of >> "unsubscribe" > sakai-dev mailing list sakai-dev@... http://collab.sakaiproject.org/mailman/listinfo/sakai-dev TO UNSUBSCRIBE: send email to sakai-dev-unsubscribe@... with a subject of "unsubscribe" |

Ok
I've done this under http://jira.sakaiproject.org/browse/KNL-316 Notes: - a couple of log lines are much pithier as the methods they call (mostly ttl and items on disk) no longer exit - backport-util-concurrent is an explicit dependency of the kernel-impl D David Horwitz wrote: Hi Ian Boston wrote: _______________________________________________ sakai-dev mailing list sakai-dev@... http://collab.sakaiproject.org/mailman/listinfo/sakai-dev TO UNSUBSCRIBE: send email to sakai-dev-unsubscribe@... with a subject of "unsubscribe" |

I've heard there are some interesting behavior (problems?) with 1.6 due
a switch toe java.util.logging instead of log4j. Seems to play havoc with classloaders according to a fellow uPortal developer who was trying to upgrade uPortal's use of ehcache. Something worth checking on, before you invest too much work in changing something in kernel. ---- Cris J H Ian Boston wrote: > On 1 Nov 2009, at 07:54, David Horwitz wrote: > >> Hi All, >> >> At the moment we are using ehcache 1.3.0.

This is the issue that I was talking about. Eric Dalquist ran into it
