Description
in the after_commit method of hypermodel, the SendPacket
operation is run which will return a promise, but it is not checked for an error state.
def self.after_commit(operation, model)
# Calling public_columns_hash once insures all policies are loaded
# before the first broadcast.
@public_columns_hash ||= ActiveRecord::Base.public_columns_hash
Hyperstack::InternalPolicy.regulate_broadcast(model) do |data|
puts "Broadcast aftercommit hook: #{data}" if Hyperstack::Connection.show_diagnostics
if !Hyperstack.on_server? && Hyperstack::Connection.root_path
send_to_server(operation, data, model.__synchromesh_update_time) rescue nil # fails if server no longer running so ignore
else
SendPacket.run(data, operation: operation, updated_at: model.__synchromesh_update_time)
end
end
rescue ActiveRecord::StatementInvalid => e
raise e unless e.message == "Could not find table 'hyperstack_connections'"
end unless RUBY_ENGINE == 'opal'
The line containing SendPacket
should be
SendPacket.run(data, operation: operation, updated_at: model.__synchromesh_update_time).tap { |p| raise p.error if p.error }
The easiest way to patch this is by adding this:
module Hyperstack
class InternalPolicy
alias original_send_message send_message
def send_message(*args, &block)
original_send_message(*args, &block).tap { |p| raise p.error if p.is_a?(Promise) && p.error }
end
end
end
This will catch the error with the smallest patch. Note the patch needs to check if its a promise, but the actual fix does not.
