Timeout exception when sending a subscription request after unsubscribing from a previous subscription #9

Closed Satswalker closed 1 year ago

Satswalker commented 1 year ago

Steps to reproduce:

  1. Make a first subscription request with Nostr.pool.subscribe and await for its returned Future to complete.
  2. Close the first subscription with Nostr.pool.unsubscribe.
  3. Make a second subscription request and watch things break. "No response from [relay URL]" log message is printed.

Observed in v0.6.1

Root cause is fairly obvious. Messages sent to relays are async operations whose Futures complete upon the relay acknowledging the message was processed. nostr_dart uses Command Results and EOSE notices as this acknowledgement however neither of these messages are returned in response to a "CLOSE" message which is sent by Nostr.pool.unsubscribe.
