fix: sshnp exit if atSign DNE, sshnpd wait for atSign to exist #211

JeremyTubongbanua · 2023-06-17T03:14:59Z

What I did

util function atSignIsActivated
sshnpd sleeps 5 seconds, if sshnp atSign does not exist
sshnp exit(1), if sshnpd atSign does not exist

Fixes issue #118

closes #188

JeremyTubongbanua · 2023-06-17T04:07:26Z

@cconstab
For sshnpd, if the sshnp atSign does not exist, do we want to exit(1), or do a while() {sleep 5} or something?

+/// Checks if the provided atSign's atServer has been properly activated with a public RSA key.
+/// `atClient` must be authenticated
+/// `atSign` is the atSign to check

Can you add into the sshnp_utils.dart please? Keeps things tidy

lib/atsign_exists.dart

+  try {
+    await atClient.get(publicKey);
+    return true;
+  } catch (e) {


Shouldn't you distinguish between errors? For example if the atServer is not reachable for some reason, that is different than getting a KeyNotFound exception

Ah, is this what you mean?

The AtClient.get exceptions are:

Throws [AtKeyException] for the invalid key formed Throws [AtDecryptionException] if fails to decrypt the value Throws [AtPrivateKeyNotFoundException] if the encryption private key is not found to decrypt the value Throws [AtPublicKeyChangeException] if the encryption public key used encrypt the value is different from the current encryption public key(at the time of decryption) Throws [SharedKeyNotFoundException] if the shared key to decrypt the value is not found Throws [SelfKeyNotFoundException] if the self encryption key is not found. Throws [AtClientException] if the cloud secondary is invalid or not reachable

The only 2 possible exceptions should be AtKeyException and AtClientException, right?

With your current implementation, it might exist, but not yet be onboarded

The exception message was incorrect
e2fd442

Oh, an atSign can have a publickey but not be onboarded?

EDIT

I find that it does not exist, as long as we bypass cache

@JeremyTubongbanua - @cconstab and I discussed this last week ... we think a while (can't fetch public key) {try; sleep} is best
