네 established가 되어야 연결된거에요 그전에 클라이언트에서 synsent로 기다립니다.

hochan222 · 2021-04-11T05:12:32Z

혹시 tester말고 webserv상태도 보여주실수있나요?

yechoi42 · 2021-04-11T05:17:24Z

그건 어떻게 확인하나요???

웹서브는 아래 메세지와 함께 스스로 죽었어요
run.sh: line 55: 2965 Killed: 9 ./Webserv config/${file_name}

아래처럼 계속 읽어오려고 시도하다 죽어요. GET MESSSAGE SUCCESS 란 문구가 안나온 걸로 봐서는, getMessage 리턴값이 SUCCESSS는 아니네요.

::1:: 5 ::
::1:: 5 ::
::1:: 5 ::
::1:: 5 ::
::1:: 5 ::
::1:: 5 ::
::1:: 5 ::
::1:: 5 ::
::1:: 5 ::
::1:: 5 ::
::1:: 5 ::
::1:: 5 ::

일단 제가 짐작하는 문제 원인은

socket 관리 실패
혹시 메세지가 잘려서 오는지...? 그래서 recv(msg_peek)만 무한정하다가 read는 못하고 죽어버리는 상황이 생기는지?

hochan222 · 2021-04-11T05:28:01Z

앗앗 죽어서 사라졌나봐요. 원래는 아래 바로나옵니다. 그러면 SENT_SYN이 나오는 이유는 accept되기전에 Webserv 가 중단돼서인것같습니다.

Sock 관리실패면 select err 9가 떳을텐데 음..

이게 동일 문제인지는 모르겠으나 지금 계속 검색중인데 close()만으로 소켓이 끊어졌다고 확신할수없는것같습니다. ( close가 바로 버퍼까지 비워주는건아닌것같습니다)

저도 온전치 못한 메세지때문인것같기도합니다 음음.. 뭔가 끊어주는 기준을 정해야할것같아요 로그는 어떤가요?

yechoi42 · 2021-04-11T05:40:54Z

Test multiple workers(5) doing multiple times(15): GET on /

Test multiple workers(20) doing multiple times(5000): GET on /

두개가 같은 요청이라서 구분을 할 수가 없네요 ㅠㅠ 이게 5워커의 요청인지 20워커의 요청인지, 20워커의 요청이 들어오기나 한 것인지... 제 생각엔 들어오지도 않았을 것 같습니다

yechoi42 · 2021-04-11T05:43:52Z

그렇네요... 왜 죽어버리지 .... 아무튼 읽지도 못한채로 죽어버리는 거니까... 반짤려서 온다고 생기는 문제는 아니겠네요.

run.sh: line 55: 3665 Killed: 9 ./Webserv config/${file_name}

이런 메세지 나오면서 죽잖아요. 혹시 3665 이게 pid 같은데, webserv의 부모 pid겠죠? cgi pid가 죽는다고 프로그램이 꺼지진 않을테니.. .

그리고 앞선 메세지에서 저희 요청이 정상처리되면 close 안하기 때문에 close 하는 부분은 지금은 없는 것 같아요. 아니면 tester의 close 문제 얘기하는 거에요?

hochan222 · 2021-04-11T05:44:52Z

생각해보니 SENT_SYN 가 서로 연결되기 전 상태니까 read peek문제가 있더라도 그 전에 발생한 문제겠네요..

hochan222 · 2021-04-11T05:49:46Z

저희쪽 close에관한 것이었는데 생각해보니 그 문제는 아닌것같아요 생각 조금 더 해보겠습니다.

ret ==0 일때도 continue를 해줬던 게 가장 큰 문제였고 그건 fail 처리해줬습니다.
그 다음 문제는 위 처럼 로그를 찍어봤는데 메세지가 잘린 채로 들어왔는데 parse를 시도하는 게 문제입니다.
아래 부분이 파싱을 시도하려하는 메세지입니다.

이거 근데 저희 한번 할 때도 오래걸리거든요... 근데 총 100번 하니까.... 시간이 이게... 아마 두시간 걸릴듯;;; 개선이 필요하긴 하겠네요

와우.............................ㅜㅡㅜ

yechoi42 · 2021-04-11T14:59:13Z

아무튼 앞에 것들의 주된 개선사항은

read 하기 전에 recv해서 read 할 양 정해줌
그 과정에서 read 할 양을 정하는 것이나 파싱 조건이 조금씩 달라지거나 놓친 게 있는데 그런 것들을 손봐줌

오늘 시도해본 것

파일을 다시 pipe fd로 바꿔보기 -> 여전히 EPIPE

	int parent_write = fd[1];
	int cgi_stdin = fd[0];

::4:: 에서 write 대신 send 써보기 -> 여전히 EPIPE
CGI 자식 프로세스에서 dup2(clientfd, STDOUT)

FATAL ERROR ON LAST TEST: Post http://localhost:8080/directory/youpi.bla: net/http: HTTP/1.x transport connection broken: malformed HTTP version "Status:"

이렇게 하니까 직접 보내지고!!!! 대신 형식이 맞지 않아서 에러가 나옵니다. 암튼 직접 물려준다는 것의 의미는 이런 것이 아닐까... 그래서 내일 시도해볼 건, 일단 헤더만 정리해주고 그 다음부터 clientfd로 직접 쏴주게요.

hochan222 · 2021-04-22T18:45:54Z

이렇게 하니까 직접 보내지고!!!!

@yechoi42 직접 보내지나 검증을 몇가지 해보았습니다.

검증

우선 검증을 위해 헤더는 동일하게 안보내주었습니다. 클라이언트로 테스트해보았는데 직접물린경우 아무것도 출력되지않습니다.

dup2(fd[0], STDIN_FILENO)

dup2(m_client_socket, STDIN_FILENO)의 경우

dup2(clientfd, STDIN_FILENO)의 경우

오류 추정

dup 방식에 문제가있다.
dup는 잘됐지만 pipe가 빨리 닫혔다

검증에 사용된 python 코드

import socket
mysock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
mysock.connect(('localhost', 8080))
cmd = "POST /directory/YoupiBanane/aa.bla HTTP/1.1\r\nAccept: */*\r\nUser-Agent: rawtester\r\nHost: localhost:8080\r\nContent-Length: 7\r\n\r\nabcdefg"
mysock.send(cmd)
while True:
    data = mysock.recv(466)
    if(len(data) < 1):
        break
    print(data.decode())
mysock.close()
