Description

In standalone the caches for static methods were reset during creation of the spring context. This does not take place anymore therefore we need to reload or empty all caches.

This is especially the second level cache (currently called CdmServiceCacher) for terms and vocabularies and all static methods (e.g. in Rank and NomenclaturalStatusType).

This is a critical issue as it is a regression and it may create incorrect or even invalid data.

Probably duplicated by #5512 and #5539

In my case it created an alternative name instead of a later homonym relationship.

r27708 should fix this.

In Mexico Rubiaceae I observered that I added NamedAreaLevel und Type to existing areas but they resulted in wrong ID in the database. This very much reminded me to this ticket. I am not 100% sure if I added level and type after changing the database connection but definetely we need to test this ticket intensively before closing.

This is not yet fixed as we watched in the past multiple times that switching between instances created serious problems as terms were referencing wrong ids after the switch.

I did now improve the first reset() functionality (reset for static methods) to include not only the Rank and NomenclaturalStatusType class but all managed term classes.
We need to check how far this solves the problem.

However, I guess that also the term term cache(s) (terms and vocabularies) need to be fully emptied/replaced. I can't see that this is already done in the code, but maybe I only look at the wrong place.

It looks like emptying the cache is done in CdmStoreConnector in this line

CdmStore.setInstance(applicationController, cdmSource);

Which calls

CdmApplicationState.setCdmServiceCacher(new CdmServiceCacher());

and calling the construtor of CdmServiceCacher calls setup() in this class which then calls

        DefinedTermBase.setCacher(this);
        CdmTransientEntityCacher.setPermanentCacher(this);
        //TermServiceRequestExecutor.setDefaultCacher(this);
        RemoteInvocationTermCacher.setDefaultCacher(this);

and resets the cache in DefinedTermBase (and others) this way

There is a cache also in TermManager !!!

This is currently not emptied when connecting to a new datasource.

I added TermManager.reset() with commit 9d700cfc23f6e13931

This needs to be checked if this fully solves the problem

Assignee changed from Andreas Müller to Katja Luther

Can you please test the results of the latest changes and see if the problem still exists by testing with data related to different term types (not only Rank and NomenclaturalStatusType).
After testing please return back to me.

Updated by Andreas Müller almost 4 years ago

Nicht wirklich, es sollte aber überall dort funktionieren, wo möglichst viele Terme sich in ihrer ID unterscheiden, weil später mal ein Term in einem "frühen" Vokabular hinzugefügt wurde. Wenn man das Arbeiten und editieren mit solchen sich ID-seitig unterscheidenden Termen nach einem Datasource wechsel testet, trat früher oft ein Fehler auf (z.B. ein falscher Rang wurde verwendet oder so). Ein klares Kochrezept habe ich aber noch nicht.
