This function creates a stanza object from a string. The string must
contain a single complete stanza. Multiple stanzas will lead to memory
leak and this is not handled in the patch.
There are situations when applications need more predictable timed
handlers that don't depend on connection status. Other usecase of
the global handlers is to manage offline connections, for example,
reconnect after a disconnection.
XEP-0077 will not be implemented as part of libstrophe's API, but an
example is provided. The example shows how to use the "raw" connection
to register a user.
Closes#54.
New boolean functions:
xmpp_conn_is_connecting()
xmpp_conn_is_connected()
xmpp_conn_is_disconnected()
These functions are backported from UnrealEngine project.
PLAIN mechanism sends password in BASE64 encoding which everyone can
read. As result, debug logs expose password and users often don't remove
it when post the logs in the Internet.
Usually, both a secure mechanism and PLAIN are used in the scenario when
username or password is incorrect. PLAIN fails in this scenario anyway.
Legacy authentication can expose password in plaintext. Since this is
not widely used mechanism, disable it by default. It can be enabled back
with connection option XMPP_CONN_FLAG_LEGACY_AUTH.
- Certificate verification is enabled for all openssl versions by
default
- xmpp_ctx_set_timeout()
- Move xmpp_ctx_set_timeout() to event loop section in strophe.h
xmpp_conn_t object can be reused with saving user's handlers.
However, saving system handlers can lead to a fail during connection
process. This is because old object may contain timed handlers for
missed features or other handlers that would handle incoming stanzas
incorrectly.
For example, XEP-0115 requires binary digest to be base64-encoded.
Add short function to simplify such a digest computation for a single
buffer. This function doesn't allocate memory. Therefore, it can't
fail and doesn't require strophe context (xmpp_ctx_t).
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.
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).
- Leave default number of keepalive probes rather than hardcoded value
- QNX and OSX use TCP_KEEPALIVE instead of TCP_KEEPIDLE
- QNX doesn't have TCP_KEEPINTVL
xmpp_conn_set_flags() and xmpp_conn_get_flags() unify interface of
connection configuration.
This interface allows compile-time check of supported features or even
run-time check. Therefore, applications can be built with older
libstrophe which doesn't support some optional flags.
