Re: [xwiki-devs] [Proposal] Some changes I would like to introduce in the internal API of the hibernate base store

Hi Devs, I would like to commit the following change on the internal API of the hibernate store: Deprecate public boolean beginTransaction(boolean withTransaction, XWikiContext context) public boolean beginTransaction(SessionFactory sfactory, boolean withTransaction, XWikiContext context) in favor of public boolean beginTransaction(SessionFactory sfactory, XWikiContext context) Deprecate public void endTransaction(XWikiContext context, boolean commit, boolean withTransaction) public<T> T execute(XWikiContext context, boolean bTransaction, boolean doCommit, HibernateCallback<T> cb) in favor of public<T> T execute(XWikiContext context, boolean doCommit, HibernateCallback<T> cb) and add new method public<T> T failSafeExecute(XWikiContext context, boolean doCommit, HibernateCallback<T> cb) Deprecate public<T> T executeRead(XWikiContext context, boolean bTransaction, HibernateCallback<T> cb) throws XWikiException in favor of public<T> T executeRead(XWikiContext context, HibernateCallback<T> cb) throws XWikiException and add new method public<T> T executeFailSafeRead(XWikiContext context, HibernateCallback<T> cb) Deprecate public<T> T executeWrite(XWikiContext context, boolean bTransaction, HibernateCallback<T> cb) in favor of public<T> T executeWrite(XWikiContext context, HibernateCallback<T> cb) throws XWikiException and add new method public<T> T failSafeExecuteWrite(XWikiContext context, HibernateCallback<T> cb) My motivation: - reduce confusion, since the current signature let you think that sub-transaction are possible, and these are not, since the withTransaction argument is unused. - provide an easy way to run potentially failing transaction, that will not do logging and neither throw. It is the responsability of the caller to manager the situation. The later could be use to easily check the state of the database during a migration for example. Is a table exists ? is column exists ? could be done by simple fail safe selection, if these fail, you are almost sure the table or column is missing. Anything against these changes ?
