eredis v2.6.2

Migration guide

Whenever there's an interface breaking change (a change in the project's major version), required migration instructions will be detailed in this file.

From [2.{0..3}.x] to [2.4.0]

Update

  • your code to depend on types from eredis: and not (imported) eredis.hrl (a simple dialyzer procedure should put into evidence what is mis-specified)
  • where you're importing the eredis.hrl header and using type X(), remove the import and use eredis:X() instead; do this for types parser_state, continuation_data, and pstate
  • your code to not depend on eredis.hrl macros NL, SOCKET_OPTS, TCP_SOCKET_OPTS, SSL_SOCKET_OPTS, RECV_TIMEOUT or SEND_TIMEOUT; copy their content from src/eredis.hrl

Remove

  • your code's import of eredis.hrl
  • your code's import of eredis_sub.hrl

From [1.x] to [2.x]

Update

  • calls to :q_async/2 and q_async/3 and matching of their asynchronous replies:
% where before you had:
eredis:q_async(Client, Command) ->
    % [...]

handle_info({response, Reply}, State) ->
    % [...]

% now you should have:
{await, ReplyTag} = eredis:q_async(Client, Command),
NewState = State#state{ reply_tag = ReplyTag }.
    % [...]

handle_info({ReplyTag, Reply}, State) when ReplyTag =:= State#state.reply_tag ->
    % [...]
