[BUG] Big issue ticket of all the bugs after testing day

[leske42]

Don't break it into smaller issues @LeaYeh let's just fix all of them

• check possible Content-Length overflow in the Header Field Validator

• implement response to 100-continue properly

• implement keepalive timeout properly ([KNOWN ISSUE] Keep-alive implementation should be different #142)

• clean up tempfiles after throwing exception

• don't create tempfiles for GET

• solve leak coming from CGI Handlers on multiple CGI request (by unique ptr?) ([BUG] Leak on more than one CGI request #155)

• Connection: close should always close the connections ([BUG] Connection: close doesn't close the connection #132)

• Close all fds before execve() in CgiExecutor (need to fix for the session)

• check for both -1 and 0 returns after read/recv/send

• delete errno logs

• ConfigParser cries if client_max_body_size doesn't end with a letter

• our chunked response probably sucks syntactically so if we respond chunked browser cries

• telnet doesn't work?? (postman gets our answer on successful DELETE but telnet just gets hangup)

• main test page has wrong links and gives 403

• GO uploader script should not print EOF error

• remove the not-critical "critical" logs from Harl

• if server name doesn't match we should not respond 404 but default to the first possibility

• redirect is leading to an infinite loop for some reason

• after refactor of config parser, POST can not create new files. It checks if the file has write permission before writing to it, but nonexisting files have no permissions

• if we send a DELETE request for the same resource more than once, we get UNKNOWN method from the parser (which results in 501 not implemented - probably the parser is not reset somewhere

• POST CGI without body quits from the 2nd attempt

• the makefile should create a tmp folder if it doesnt exist yet because our webserver needs it for operation

• use of throw in all constructors needs to be revised (maybe function try blocks can help)

• Create demo config to answer the question: https://hackmd.io/2BmEOeDlTluQt0QLxf8YJA

• Your server must have default error pages if none are provided.

• You can’t use fork for anything other than CGI (like PHP, or Python, and so forth).

• root or alias directive is missing in location block for redirect

• epoll_create1 should be epoll_create

• make a simple makefile

• Setup multiple servers with different hostnames (use something curl)

• leak when bind() failed

• http://127.0.0.1:8080/features/upload.html doesn't work

• review all conf files again
