- Add AggregateFormulaContext with ability to override the default via DatabaseBuilder
- Add group_concat, string_agg, listagg to set of known aggregation functions
* Version 16.1.0
* Improve javadoc for Query setUseQueryCache() and unmodifiable
Since 16.x a query using the query cache returns unmodifiable object graphs.
* Use autocommit false with findIterate for Postgres
* Use autocommit false with findIterate for Postgres
* Use autocommit false with FindDto queries for Postgres
* Use autocommit false with SqlQuery findIterate queries for Postgres
* Ensure that TransactionFactory.createReadOnlyTransaction() returns an ImplicitReadOnlyTransaction
This change changes TransactionFactoryTenant.createReadOnlyTransaction() to return a ImplicitReadOnlyTransaction, as that is now used to support Postgres use of cursors with findIterate style queries.
e.g. DatabaseBuilder.queryPlanExplain("explain (verbose)")
Also changes Postgres default explain to be:
explain (analyze, costs, verbose, buffers, format json)
So we can no longer dynamically change the Clock being used and instead for testing purposes need to create the Database with a test clock instance as needed.
Refer to the ExtendedServerTest for an example
- Adds new exceptions UnloadedPropertyException and UnmodifiableEntityException
- Change InterceptReadOnly to use these exception instead of IllegalStateException
- Change collections BeanSet, BeanList, BeanMap from using IllegalStateException to UnsupportedOperationException [to bring these in line with JDK unmodifiable collections]
As HelpScopeTrans isn't in an exported package it's use fails with an error in module path. This adds AOPTransactionScope in the exported package io.ebean.plugin and moves the required methods from SpiEbeanServer to SpiServer to support this move.
This also requires an associate change in ebean-agent to support this feature which will be in ebean-agent 14.9.0.
Although this is ok, makes me think that another option is just to have query.setReadOnly(true)
to mean ... readOnly + disableLazyLoad + error reading unloaded property or collection. As in,
readOnly true without these extra things does not that good [as in the existing readOnly does
not seem very good/safe/useful to use].
Currently, the SELF response type of QueryBuilder returns as Object when really we want it to return the SELF generic type of QueryBuilder, QueryBean, IQueryBean etc
Note that this change requires an updated ebean-agent
