function to our API without discussion the consequences of. By design
the signature algorithm is a property of the signer's key and can't be
set arbitrary. The library is named GnuPG Made Easy so we should not
burden the user with an API to select stuff which can only be done by
the backend. Changes in gpgme require support by the backend. If we
have the requirement to implement it, it will be done as a global
configuration option for signers or as meta-data asscociated with a
certificates for recipients. I habe not found this as a requirement of

This patch has gotten a bit large... mmh. 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. As a bonus, there
will be a function to access gpgme->wait, so that the operations
can truly be implemented with their _start function.
