minor #34155 Revert SyncTransport simplification and fix properly (weaverryan)
This PR was squashed before being merged into the 4.4 branch (closes #34155). Discussion ---------- Revert SyncTransport simplification and fix properly | Q | A | ------------- | --- | Branch? | 4.4 | Bug fix? | yes | New feature? | no | Deprecations? | no | Tickets | Fix #34115 (and also related to #34066) | License | MIT | Doc PR | Not needed In #34069, I made `SyncTransport` simpler by removing that transport class and making the whole things a config trick. I felt GREAT about that solution... until i realized two big problems: 1) It kills using env vars for `sync://` because we read the config values at build time - #34115 - that could probably be fixed by adding a factory, but then there is also the next problem 2) If someone routed a message to `[async, sync]` (weird, but allowed), my #34069 config solution basically maps this internally to `[async]`, which actually causes the message to *not* be handled immediately. Basically, my solution only worked if you route a message ONLY to one sync transport, but fails if you route to multiple transports. So... this fixes things in a less-cool, but sensible way: A) The first commit reverts #34069 exactly B) The second commit solves the issue that we need to know if a message is being handled in a "worker" context or not, so middleware can decide if they should reset things before/after handling things. Previously we were using `ReceivedStamp` to know this. But because `SyncTransport` also "receives" the message and adds this stamp, it's not enough. To fix this, I added a new `ConsumedByWorkerStamp` that clearly means: "This message is being handled by a worker" (and so, you might want to "reset" some things before/after handling). Thanks!
