rCOMMe7885e5a97fa: [services][identity] wallet login
Summary

Full implementation of wallet login. Steps:

  1. Parse SIWE message and signature from request
  2. Verify message using siwe-rs crate
  3. If verification is successful, generate a token, store it in the token table in DynamoDB, and then return it to the caller

Note that PAKE login is not covered here. It will be in a separate diff.

Test Plan

Successfully signed in with a metamask wallet

changed the type of token in the .proto file to string, so this is the corresponding code change

Error case isn't handled

72 ↗(On Diff #13549)

When would this be None?

73 ↗(On Diff #13549)

This is really hard to read, please refactor. The error handling in the match arms is heavily duplicated. For starters, make a subroutine that returns a Result, and in here do the if let Err(err) = result { log and break } thing once.

This revision now requires changes to proceed.Jun 17 2022, 11:53 AM

handle unhandled error case and unhandled option case

oneof fields are completely optional, which is why this can be None. we are reconsidering the use of oneof across all our .proto files, but i've handled the None case in the latest revision.

Don't love how I'm repeating myself here but wasn't sure how to avoid it

What is the purpose of it?

I think you can create a function that contains the repeated logic

MyIdentityService doesn't implement Debug, so we have to skip self when we do tracing

Yeah, agreed. Made it a little better in a subsequent diff that handled PAKE login, and have a diff out to improve it further
