Remove gRPC code previously used for the xpring SDK & enable gRPC on localhost by default #4272

cjcobb23 · 2022-08-11T22:06:09Z

There was a lot of gRPC code in rippled that has long been deprecated. It was used for the xpring sdk, which has been abandoned. Some of the gRPC code is used for reporting mode and clio however. This PR removes the code that is no longer needed, and only retains the gRPC code needed for clio and reporting mode.

HALLELUJAH!

After a first pass I have a couple of questions

cfg/rippled-example.cfg

-#port = 50051
-#ip = 0.0.0.0
-#secure_gateway = 127.0.0.1
+[port_grpc]


Why are we uncommenting this in the rippled-example.cfg. Do we want gRPC to be enabled by default?

We talked about this in the huddle. I asked if we could uncomment this by default, and the agreement was yes if the xpring sdk code was removed.

Do we use this in Clio or reporting mode, or only get the LedgerRange from the ledger subscription stream?

We don't use this in clio or reporting mode

Can we also remove GetLedgerDiff() and GetLedgerEntry? AFAIK, Clio only uses GetLedgerRequest and GetLedgerDataRequest

Those RPCs are not part of the xpring sdk, and I actually think they could be useful. If we want to remove them, we should discuss and do it as part of a separate PR.

 populateJsonResponse(


I don't actually know what this looked like before we added these gRPC methods, so take what I say next with a grain of salt.

Should we leave doTxHelp and populateJsonResponse as their own functions, or move it into doTx(). It occurs to me that we may have split this out to enable code reuse between the gRPC and JSON-RPC endpoints.

Is it worth leaving doTxHelp as a helper function?

I thought about this. We could move it, but I think since we already went through the work of breaking up this function, we should keep the helper function as is. What if we want to add a different response interface in the future? The helper function would be useful. I don't see it causing a problem as is.

Why are we removing this test? Flagging this because it's in ReportingETL_test.cpp

GetAccountInfoRequest is removed. This won't compile if we leave it.

Thanks so much for taking care to this @cjcobb23! It's great to see so much of this code gone. I left a couple of comments that may be relevant. But other than those this looks to me like it is good to go. 👍

Surprised to see this stanza un-commented as part of this pull request. There should be very few circumstances where this is useful, no? I could imagine it left commented out or even removed?

This is just to make it easier for people to run clio, since clio uses this port to talk to rippled. Though now that I'm thinking about it, it might be best to change the IP to 127.0.0.1, so that way the port will only listen locally by default. If someone is running clio remotely, they'll need to modify their config anyways.

scottschurr

Thanks for the update @cjcobb23. I think there are a couple more things that need to be tuned.

The RippledCore.cmake file needs to have the KnownFormatToGRPC_test.cpp file removed.
The ordering.txt file needs to be tweaked so the levelization CI test passes.

If it's helpful, here's a commit that makes those changes: scottschurr@f5d9f05

Once those changes are made I think this pull request is good to go.

👍 Looks great! Thanks.
