Operating System: SCO OpenServer
PHP Version: 4.4.1
New Comment:
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

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.

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.
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'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,
Dean

Description:
------------
I am having random failure on making a connection to MySQL. This the
code used to make the connection and has been for several years.
if (!$this->linkid =
mysql_connect($this->host,$this->user,$this->pass))
DBError(mysql_errno(),mysql_error(),"LINKID-$db",$this->mailerr,$this->sendto);
The following error is returned randomly however it happens usually
right after starting apache or after a period of inactivity:
2002 - Can't connect to local MySQL server through socket
'/d/mysql/var/mysql.so
ck' (-2146870980)
Starting with version PHP 4.3.0 is when the problem started. Version
4.2.x does not have this problem. I compiled every version until I
found where the problem started. I am currently trying to move from
4.0.6 to 4.4.1 but need to get this issue addressed.
My system:
SCO OpenServer 5.0.4 and 5.0.6
MySQL 4.1.15
Apache 1.3.34
Reproduce code:
---------------
if (!$this->linkid =
mysql_connect($this->host,$this->user,$this->pass))
DBError(mysql_errno(),mysql_error(),"$this->linkid
LINKID-$db",$this->m
ailerr,$this->sendto);
Expected result:
----------------
I expected to get a resource ID returned.
Actual result:
--------------
2002 - Can't connect to local MySQL server through socket
'/d/mysql/var/mysql.so
ck' (-2146870980)
