submitAndWait in standalone mode

[tequdev]

We cannot use submitAndWait in a standalone mode network.

I propose to add a standalone flag to the submitAndWait parameter so that the ledger_accept command can be executed in the process.

Ideally, it should be able to run in stand-alone mode and on other testnets with nearly identical simple code, although it is possible to do so in other ways.

Is this necessary when you can just use submit and run ledger_accept yourself?

Hi @mvadari @tequdev

Is it known that submitAndWait does not work with a ledger_accept call? In our initial testing, it seems running ledger_accept from the command line interface seems to unblock the submitAndWait call, where calling it via ws or rpc does not.

We built some code into a library using submitAndWait, and wanted to test it against a stand-alone rippled service. If submitAndWait is a supported function, it seems odd that it wouldn't be testable in this way.

submitAndWait is intended to be used with production-style networks. If you're using a standalone node, you can get the same effect much more efficiently just by writing your own helper function that looks something like this:

function fakeSubmitAndWait(tx) {
  submit(tx)
  await client.request({command: "ledger_accept"})
  return await client.request({command: "tx"})
}

Alternatively, you can also just do a basic setInterval to close ledgers yourself - submitAndWait will work with this.

const intervalId = setInterval(() => {
  await client.request({command: "ledger_accept"})
}, 2000);
