Fabien Potencier 5fe3701f05 feature #30020 [Messenger] Ensure message is handled only once per handler (keulinho, sroze) ... This PR was merged into the 4.3-dev branch. Discussion ---------- [Messenger] Ensure message is handled only once per handler Add check to ensure that a message is only handled once per handler Add try...catch to run all handlers before throwing exception | Q | A | ------------- | --- | Branch? | master | Bug fix? | no | New feature? | yes | BC breaks? | no | Deprecations? |no | Tests pass? | yes | Fixed tickets | #27215 | License | MIT | Doc PR | Todo This would make error handling and retrying of messages much more easier. As statet here https://github.com/symfony/symfony/pull/27008#issuecomment-384677065 there is currently no way to retry a for all failed handlers if there are mutliple handlers and just some throw an exception. Also if an Exception in an handler occurs the execution chain is disrupted and the other handlers are never invoked. With this change it is easily possible to create an userland middleware that catches the `ChainedHandlerFailedException` and does some custom retry logic. If you ensure that the `HandledStamps` on the `Envelope` are preserved the message will be handled just by the failed handlers Commits ------- 2e5e910229 Rename exception, add change log and a few other things e6e4cde5fc Ensure message is handled only once per handler		2019-04-06 14:59:11 +02:00
