At the same time, > the project is very inconsistent in its usage of these APIs, so this work > includes a number of improvements to the coherency of the codebase. > This ticket introduces new abstractions and standardises old ones, migrating > all blocking concurrency operations besides Futures returned by Executors to > these new APIs. This includes a migration of SimpleCondition to a new > Conditioninterface, new CountDownLatch and Semaphore interfaces, and new > static factory methods for creating these objects (as well as WaitQueue) that > can be intercepted by byte weaving. Additionally the internal Netty Future > implementation is improved to support more general use (though this is only > fully realised in a later ticket), OpOrder is improved to more easily support > mocking WaitQueue. > Finally we standardise the propagation of InterruptedExecption, with the new > UncheckedInterruptedException, so that simulations may be terminated cleanly. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
