The main thing that + happens here is that error values are now not determined in the + operation function after gpgme_wait completed, but in the status + handler when EOF is received. It should always be the case that + either an error is flagged or EOF is received, so that after a + gpgme_wait you should never have the situation that no error is + flagged and EOF is not received. One problem is that the engine + status handlers don't have access to the context, a horrible + kludge works around this for now. All errors that happen during a + pending operation should be catched and reported in ctx->error, + including out-of-core and cancellation. This rounds up neatly a + couple of loose ends, and makes it possible to pass up any errors + in the communication with the backend as well.
