[ANN] transaction-handling plugin

[Daniel Henrique Alves Lima]

Hi, everybody.

It's a backport of http://jira.grails.org/browse/GRAILS-7093

https://github.com/daniel-lima/grails-transaction-handling-plugin
http://grails.org/plugin/transaction-handling

Usage examples:

https://github.com/daniel-lima/grails-transaction-handling-plugin/blob/master/test/integration/transaction/handling/DynamicMethodsTests.groovy

        TestUser.withTransaction {
        }


        TestUser.withTransaction(isolation: 'readUncommitted') {
        }

        TestUser.withTransaction(readOnly: true, timeout: 'default') {
        }

        TestUser.withTransaction(propagationBehaviorName: 'PROPAGATION_MANDATORY', timeout: 765) {
        }


        TestUser.withTransaction(propagation: "mandatory") {
        }


        TestUser.withNewTransaction {
        }


        TestUser.withNewTransaction(isolationLevel: TransactionDefinition.ISOLATION_SERIALIZABLE) {
        }


        TestUser.withNewTransaction(propagation: 'supports', readOnly: true, timeout: 612) {
        }


        TestUser.withNewTransaction(isolationLevelName: 'ISOLATION_REPEATABLE_READ') {
        }


Best regards,

Daniel.

    Hi.

    (I still need to document this plugin properly :-|).

    "Configurable defaults" are now available:

https://github.com/daniel-lima/grails-transaction-handling-plugin/blob/master/grails-app/conf/TransactionHandlingDefaultConfig.groovy

    If Config.groovy contains:

    grails.plugin.transactionHandling.programmatic.timeout = 30000
    grails.plugin.transactionHandling.programmatic.readOnly = true

    TestUser.withTransaction {

  }

        or

  TestUser.withTransaction(isolation: 'readUncommitted') {
  }


        Will create read only transactions with timeout equal to 30000


    grails.plugin.transactionHandling.global.timeout = 70000

    Will affect the defaultTimeout of the installed transactionManager,
influencing *any* transaction.

    Best regards,

       Daniel.
