gen_tcp send non-blocking in erlang?. Does gen_tcp supports non-blocking send ?I have tried gen_tcp:send which returns the ok while the packets has not been sent to the receiver.

whenever i use a very large GET header, like Erlang › Erlang Questions gen_tcp send non-blocking in erlang? It is a very, very dangerous practice, because you loose control over your program with non-blocking send. First step that you MUST do is setting send_timeout on socket. By default it is infinity and it means that your process may get blocked forever trying to push data. netstat for erlang gen_tcp.
Each send operation generates the header, and the header is stripped off on each receive operation. The 4-byte header is limited to 2Gb [message length]. As the examples at Erlang gen_tcp:recv (Socket, Length) semantics confirm, when {packet,0} is specified, … The acceptor process calls gen_tcp:accept, and when the call returns, a new process responsible for handling the data is spawned. The client socket is given to this process via gen_tcp:controlling_process, and the acceptor calls gen_tcp:accept again waiting for new connections.

Erlang gen tcp packet option. Erlang -- gen_tcp, Use gen_tcp:shutdown(Sock, write) to signal that no more data is to be sent and wait for the read side of the socket to be closed.
gen_tcp and large HTTP headers. dear list, i'm using gen_tcp in {packet, http} and {active, once} modes to receive HTTPrequests. whenever i use a very large GET header, like Erlang › Erlang Questions
Defaults to {gen_tcp, tcp, tcp_closed, tcp_error, tcp_passive} for TLS (for backward compatibility a four tuple will be converted to a five tuple with the last element "second_element"_passive) and {gen_udp, udp, udp_closed, udp_error} for DTLS (might also be changed to five tuple in the future). Can be used to customize the transport layer. :gen_tcp.accept() will accept the connection on listening socket. Receiving Packets To receive the packets inside the GenServer , we have to define a handle_info/2 function. The JIT-compiler is enabled by default on most x86 64-bit platforms that have a C++ compiler that can compile C++17. To verify that a JIT enabled emulator is running you can use erlang:system_info (emu_flavor).

It has been a long process with three release candidates before the final release. We decided this year to try to get one month more testing of the major release and I think that the extra time has paid off. We’ve received many bug reports from the community about large and small bugs that our internal tests did not find. gen_tcp有false,active,once,N这些选项，active是不提供流量控制的，之前没读懂，疑惑了好久，后面仔细看了看，也许是这个意思：erlang的话每个进程都有个邮箱，消息就放在邮箱中，在active模式下会无限的从底层接收缓存中提取消息到邮箱中，邮箱满了消息就会丢失。

gen_tcp_server is a behaviour for writing TCP servers. It supports: - OTP supervisor structure, code upgrades and debuging - listening on multiple ports - {packet, X} - flow control - timeouts - latency profiler - limiting number of connections - dynamic reconfiguration
gen_server is really a server that operates using Erlang's message passing as its base protocol. We can graft a TCP server onto that framework, but it requires some work. The Structure of a Network Server Erlang/OTP. Contribute to erlang/otp development by creating an account on GitHub.
