◆ change_user_for_reuse()

static classic_protocol::message::client::ChangeUser change_user_for_reuse ( Channel &  src_channel,
ClientSideClassicProtocolState &  src_protocol,
ServerSideClassicProtocolState &  dst_protocol,
std::vector< std::pair< std::string, std::string > >  initial_connection_attributes 
)
static

◆ classic_proto_append_attribute()

static stdx::expected< size_t, std::error_code > classic_proto_append_attribute ( std::string &  attrs_buf,
const std::string &  key,
const std::string &  value 
)
static

◆ classic_proto_decode_and_add_connection_attributes()

static stdx::expected< std::string, std::error_code > classic_proto_decode_and_add_connection_attributes ( std::string  attrs,
const std::vector< std::pair< std::string, std::string > > &  extra_attributes 
)
static

merge connection attributes.

  • verifies the connection attributes
  • appends new attributes.
  • sets attributes back to the client-greeting-msg
Returns
bytes appended on success, std::error_code on error.

◆ classic_proto_verify_connection_attributes()

static stdx::expected< void, std::error_code > classic_proto_verify_connection_attributes ( const std::string &  attrs)
static

verify connection attributes are sane.

connection attributes are a key-value-key-value-...

  • decodes as var-string
  • each key must have a value

◆ client_ssl_connection_attributes()

static std::vector< std::pair< std::string, std::string > > client_ssl_connection_attributes ( const SSL *  ssl)
static

router specific connection attributes.

Parameters
[in]sslpointer to a SSL struct of the client connection. May be nullptr.

◆ scramble_them_all()

static std::optional< std::string > scramble_them_all ( std::string_view  auth_method,
std::string_view  nonce,
std::string_view  pwd 
)
static

◆ strip_trailing_null()

static auto strip_trailing_null ( std::string_view  s)
static

remove trailing \0 in a string_view.

returns the original string-view, if there is no trailing NUL-char.

◆ vector_splice()

template<class T >
std::vector< T > vector_splice ( std::vector< T >  v,
const std::vector< T > &  other 
)

splice two vectors together.

appends all elements of other to the vector v.
