* http: Add reference counting to the session object.Werner Koch2014-05-053-47/+100
| | | | | | | | | | | | | | | | | * common/http.c (http_session_t): Add field "refcount". (_my_socket_new, _my_socket_ref, _my_socket_unref): Add debug code. (send_request, my_npth_read, my_npth_write): Use SOCK object for the transport ptr. (http_session_release): Factor all code out to ... (session_unref): here. Deref SOCK. (http_session_new): Init refcount and transport ptr. (http_session_ref): New. Ref and unref all assignments. -- Having the reference counted session objects makes it easier for the application to pass around only an estream. Without that the application would need to implement an es_onclose machinery for the session object.

| | | | | | | | | | | | | * agent/cvt-openpgp.c (get_keygrip, convert_secret_key) (convert_transfer_key): Follow newer (>= 1.6) libgcrypt API, which does not distinguish the detail.

(start_new_gpg_agent): Use an absolute name for the socket and pass option --homedir to the agent. (start_new_dirmngr): Use an absolute name for the --homedir. -- This patch makes gpg's --homedir option behave again like in older versions. This is done by starting a new agent for each different home directory. Note that this assumes --use-standard-socket is used which is the default for 2.1.
* common: Add functions make_absfilename and make_absfilename_try.Werner Koch2014-04-223-2/+174

| | | | | | | | | | * agent/cvt-openpgp.c (convert_to_openpgp): Fix use gcry_sexp_extract_param. * g10/export.c (do_export_stream): Provide a proper prompt to the agent. -- NB: The export needs more work, in particular the ECC algorithms.

| | | | | | | | | * g10/passphrase.c (gpg_format_keydesc): Add mode 2. Change strings. * g10/keydb.h (FORMAT_KEYDESC_NORMAL, FORMAT_KEYDESC_IMPORT) (FORMAT_KEYDESC_EXPORT): New. Use them for clarity. -- The use of the term "certificate" was more confusing than helpful.

(ssh_key_extract_comment): Rewrite using gcry_sexp_nth_string. -- To make the code easier readable most of the Ed25591 work has been done using a new explicit code path. Warning: Libgcrypt 1.6.1 uses a non optimized implementation for Ed25519 and timing attacks might be possible. While working on the code I realized that it could need more rework; it is at some places quite baroque and more complicated than needed. Given that we require Libgcrypt 1.6 anyway, we should make more use of modern Libgcrypt functions.
