I've done some more research. I took the ext/mysql/php_mysql.c and ext/mysql/php_mysql.h files from version 4.2.3 and copied them into the 4.4.1 tree. Recompiled and installed. The problem has gone away. So, somewhere therein lies the trouble. I'll continue to pursue the cause and if I figure it out I'll let you know what I find. The one question I have is, if I have questions regarding specific functions or variables, can I get answers to those questions?

Thanks,

Did you happen to check the diff between those files? It's kinda hard to know WHAT change caused this problem..

Did you use the --with-mysql-sock configure option?
Did you try using the "mysql.default_socket" php.ini option?

I did not use the --with-mysql-sock configure option. I'll try that and see what happens. There were quite a few differences. I'll begin going through them tomorrow by first concentrating on the connect function.

Something I noticed was that 4.2.3 will take a couple of seconds to connect and is successful everytime. 4.4.x gets an error immediately two times in a row and then successfully connects on the third time. This is consistently repeatable by stopping and restarting apache.

So, I'll start first by looking at timeout handling in the connection function. I wish I knew how to get this into the visual debugger so that I could place break points and watch execution. But what I'll do is fopen a file and write the contents of memory variables I deem suspect. It's a slow process but it works.

Well, compiling with --with-mysql-sock did not make any difference and neither did allowing it to use the default socket. However, I did take the php_mysql_do_connect function out of 4.2 php_mysql.c and put it in place in the 4.4.1 php_mysql.c and then everything worked. So I do believe there may be a timing issue. I'll let you know what I find.

Here is what I've found so far. There is a new call to a function called mysql_options in the php_mysql_do_connect funciton. When I comment that out, everthing works OK:

      mysql = (php_mysql_conn *) emalloc(sizeof(php_mysql_conn));
      mysql->active_result_id = 0;
#if MYSQL_VERSION_ID > 32199 /* this lets us set the port number */
      mysql_init(&mysql->conn);

            fprintf(xfp,"connect_timeout: %ld\n",connect_timeout);


RIGHT HERE: Line 778 in ext/mysql/php_mysql.c

      if (connect_timeout != -1)
            mysql_options(&mysql->conn, MYSQL_OPT_CONNECT_TIMEOUT, (const char *
)&connect_timeout);

If I comment that line then everything works. Another thing, I tried setting the timeout value to -1 in php.ini file but it's ignored in program. It always has a value of 60. I have verified that the correct php.ini file is being read.

mysql_real_connect returns NULL after setting mysql_options has executed. The MySQL version I'm using is 4.1.16.


      if (mysql_real_connect(&mysql->conn, host, user, passwd, NULL, port, socke
t, client_flags)==NULL) {
#else
      if (mysql_connect(&mysql->conn, host, user, passwd)==NULL) {
#endif
         /* Populate connect error globals so that the error functions can read
them */
         if (MySG(connect_error)!=NULL) efree(MySG(connect_error));
         MySG(connect_error)=estrdup(mysql_error(&mysql->conn));
         php_error_docref(NULL TSRMLS_CC, E_WARNING, "%s", MySG(connect_error));
#if defined(HAVE_MYSQL_ERRNO)
         MySG(connect_errno)=mysql_errno(&mysql->conn);
#endif


Is it possible that you guys could look at this from this point? If you need me to do anything just let know.

Thanks,
Dean

Doesn't look like PHP problem to me.
Please report this issue to MySQL Team (with all the details you've wrote in the last post).
