Default opening tag doesn't allow to implement XEP-0174. In this case
client needs to send specific attributes. As solution user passes
attributes that are sent inside opening tag. Previous variant of this
function is renamed to xmpp_conn_open_stream_default().
The way to pass attributes is not the best one, but it's used to conform
existent interface of xmpp_stanza_get_attributes().
Remove "raw" suffix from functions that work with a raw connection.
Previously this was incremented, but not decremented. I've corrected
the code to decrement it. It doesn't appear to be used anywhere, but
it is helpful to implement xmpp_graceful_stop().
Leave default configuration. A particular server closes tcp connection
during negotiation otherwise.
tls_schannel is still broken and tls_read() fails with
SEC_E_UNSUPPORTED_FUNCTION error.
This function is similar to xmpp_connect_client(), but doesn't perform
authentication. Instead, it calls user's connection handler immediately
after establishing the connection. Hence, user can implement own
authendication or registration procedures.
Such a "raw" connection can be useful when user interaction is required
(e.g. Data Forms in XEP-0077, OAuth2).
* Removed dependency from internal headers in rand.h. xmpp_rand
interface can be public in the future;
* xmpp_rand functions accept xmpp_rand_t object instead of xmpp_ctx_t.
If interface function returns char* the result must be freed with
xmpp_free().
In case of const char* the result must not be changed by user. Also, the
result is valid only during stanza lifetime.
Store keepalive parameters in conn object. This allows call the function
with a disconnected conn. Also, the parameters are not cleared on
reconnect and applied once a socket is created.
If `id == NULL' there were two issues: use-after-free error or
logging wrong error description.
Also open stream handler was called even when error occured and
conn object was disconnected.
Disconnected xmpp_conn_t object can be connected again. The object
is reset before connection, but the next fields remain untoucned:
* all handlers
* flags
* jid and password
Main use-case of this change is reconnect when an error occurs.
