Function Documentation

change_user_for_reuse()

static classic_protocol::message::client::ChangeUser change_user_for_reuse ( Channel *  src_channel, ClassicProtocolState *  src_protocol, ClassicProtocolState *  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]

ssl

pointer 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.
