Yaws + SSL in non Win32 OS

[Inswitch Solutions]

Hi Peter,

I've three more patches which I've been asking about to Ericsson support, but without any feedback from them.
The following happens on Win32 + Yaws web server with latest patches and SSL enabled + otp_LXA_11930_win32_R10B.exe (licensed) :

1) FD requests growing and never been released from the FD set (memory consumed).
static void close_and_remove_connection(Connection *cp) 
{
+ FD_CLR(cp->fd, &readmask);     // release read FD
+ FD_CLR(cp->fd, &writemask);    // release write FD
+ FD_CLR(cp->fd, &exceptmask);  // release exceptions FD

 safe_close(cp->fd);
 remove_connection(cp);
}

2) When a client disconnects the read function fails with SSL_ERROR_SYSCALL and the port starts looping endlessly over the same internal state (CPU 100%).
Try OpenSSL "s_client -connect localhost:443 -prexit" with a local Yaws web server and then exit from the console opened and also happens when browsing web pages.

I have modified line 1077 of esock.c with:
+   } else { //if (cc == 0) {  

3) Form upload for more than 120kb fails (http://yaws.hyber.org/upload0.yaws used)
I have increased
+ #define RWBUFLEN       (120*1024)


This is the only way I've found to solve the above issues and I'd like to share this knowledge with the Erlang list.
May be there are some other approaches.
