well, come to think of it, most of the time I'll produce nothing whatsoever. Just give me a guitar, a Biro and the back of an envelope, and. Like many musicians, I'll take all the technological help I can get in the studio, but I'm a complete Luddite when it comes to songwriting. Or can they? The people behind Masterwriter certainly think so. Will complete immediately and return zero bytes.Īlso I could have just memset-ed buff to 0 every time, but I guess, checking one int = 0 costs much less CPU that memset-ing 2048 bytes!Įdit: this socket is also in blocking mode, so it was very surprising for me to learn that it can suddenly stop blocking and start spamming zeros.Computers may have taken over every aspect of the recording process, but they still can't help you write a good song. Method, and all available data has been received, the Receive method If the remote host shuts down the Socket connection with the Shutdown Documentation from C# Receive method is more clear and maybe that's exactly how read(2) works with sockets too: Maybe it works differently with sockets that with normal files. No bytes are read, and read() returns zero. If the file offset is at or past the end of file, The file offset, and the file offset is incremented by the number On files that support seeking, the read operation commences at In documentation its super vague and not clearly written: And I was sure it's browser spamming me with requests. buff was reusing it's last request when read(2) actually received nothing, 0 bytes. Terminating!Īnd finally started to see real picture. Terminating!Ĭlient Reader Thread 9 received empty request. Terminating!Ĭlient Reader Thread 8 received empty request. I got this result instead of request spam: Client Reader Thread 7 received empty request. Printf("Client Reader Thread %d received empty request. When I remade loop start to this: while(1) But anyways, It actually didn't contain any junk data, but It retained past request from client in this thread, for example: GET /upd HTTP/1.1. It was really stupid, I know, because its local variable and it's not inited with zeroes automatically like global or statics. So, I assumed that buff will get destroyed at the end of loop and recreated each time. Start of my reader threads was like this: while(1) Turns out I was misled by my own poor buffer placement and also very stealthy read(2) special feature that is never mentioned in any tutorials and only very indirectly mentioned in man-page. It's normal for browser to open 2 sockets for 1 tab – one for base HTML page and other for EventSource? I guess it can open as many as it would like, right? Is this normal behavior for browser and why it happens? Does all browsers behave like that or only Chromium based? After that my server is gets shut down by SIGPIPE (writing to closed socket, probably). But at the moment when I close site tab it sends loads of requests non-stop. It uses EventSource to send real time updates to browser. Master Writer update operation: WRT_DEFAULTS! Master Writer update operation: WRT_UPDATE_HEAD!
