as_socket_connect_fd()

static bool as_socket_connect_fd ( as_socket_fd fd, struct sockaddr * addr, socklen_t size )

inlinestaticprivate

Connect to non-blocking socket.

Definition at line 152 of file as_socket.h.

References AS_CONNECTING, and as_last_error.

as_socket_create()

int as_socket_create ( as_socket * sock, int family, as_tls_context * ctx, const char * tls_name )

private

Create non-blocking socket. Family should be AF_INET or AF_INET6. Return zero on success.

as_socket_create_and_connect()

private

Create non-blocking socket and connect.

as_socket_create_fd()

int as_socket_create_fd ( int family, as_socket_fd * fdp )

private

Create non-blocking socket. Family should be AF_INET or AF_INET6. Return zero on success.

as_socket_current_tran()

static bool as_socket_current_tran ( uint64_t last_used, uint64_t max_socket_idle_ns )

inlinestaticprivate

static bool as_socket_current_trim ( uint64_t last_used, uint64_t max_socket_idle_ns )

inlinestaticprivate

Is socket idle within limit for trimming idle sockets in cluster tend thread.

Definition at line 207 of file as_socket.h.

as_socket_deadline()

static uint64_t as_socket_deadline ( uint32_t timeout_ms )

inlinestaticprivate

Calculate future deadline given timeout.

Definition at line 229 of file as_socket.h.

as_socket_error()

as_status as_socket_error ( as_socket_fd fd, struct as_node_s * node, as_error * err, as_status status, const char * msg, int code )

private

Create error message for socket error.

as_socket_error_append()

void as_socket_error_append ( as_error * err, struct sockaddr * addr )

private

Append address to error message.

as_socket_get_tls_context()

static as_tls_context * as_socket_get_tls_context ( as_tls_context * ctx )

inlinestaticprivate

Return TLS context only if exists and not for login only.

Definition at line 110 of file as_socket.h.

References as_tls_context::for_login_only.

void as_socket_init ( as_socket * sock )

private

Initialize an as_socket structure.

as_socket_read_deadline()

as_status as_socket_read_deadline ( as_error * err, as_socket * sock, struct as_node_s * node, uint8_t * buf, size_t buf_len, uint32_t socket_timeout, uint64_t deadline )

private

Read socket data with future deadline in milliseconds. If deadline is zero, do not set deadline.

as_socket_start_connect()

Definition at line 100 of file as_socket.h.

References as_tls_context::for_login_only.

as_socket_validate_fd()

int as_socket_validate_fd ( as_socket_fd fd )

private

Peek for socket connection status using underlying fd. Needed to support libuv.

Returns

0 : socket is connected, but no data available. > 0 : byte size of data available. < 0 : socket is invalid.

as_socket_wrap()

bool as_socket_wrap ( as_socket * sock, int family, as_socket_fd fd, as_tls_context * ctx, const char * tls_name )

private

Wrap existing fd in a socket. Family should be AF_INET or AF_INET6.
