 Bug Type:         MySQL related
 Operating System: FreeBSD 4.8-RELEASE
 PHP Version:      4.3.1
 New Comment:

here is snip from phpinfo() about mysql:
MySQL Support enabled 
Active Persistent Links  0  
Active Links  0  
Client API version  4.0.12  
MYSQL_MODULE_TYPE  external  
MYSQL_SOCKET  /tmp/mysql.sock  
MYSQL_INCLUDE  -I/usr/local/include/mysql  
MYSQL_LIBS  -L/usr/local/lib/mysql -lmysqlclient  

mysql servers lives not in the same place webserver does. earlier php
was compiled with 3.23.55 client library, then I decided to compile it
with 4.0.12. it didn't make sense. I'm not sure it's PHP bug natively,
but I'm mainly curious about why it "fails to use password" ?

one more thing to say - these systems are loaded enough, i.e.
mysqladmin reports 15.968 queries per second, so I said before, it's
hard to repeat this error in, to say, normal conditions.

What makes you think it's PHP bug, and not bug in the 
fairly new Mysql4 ?? Did this happen with Mysql 3.23.xx ?

Are you using the bundled mysql library or did you compile 
PHP with the mysql4 client library? Check your phpinfo() 
output for mysql section for the API version.

Does this happen with CLI or with some server module?

As I said, seems like password retrieval makes no difference. I have
connectdb() function which look like this:
function connectdb() {
        global $mysql_host, $mysql_user, $mysql_pass, $dbid;
       	$dbid = mysql_connect( $mysql_host, $mysql_user, $mysql_pass);
        if(!$dbid) {
        $file = fopen("/tmp/mysql-err", "a+");
        $line  = $_SERVER['PHP_SELF'] . ":" . date("Y-m-d H:i:s");
        $line .= ":$mysql_host:$mysql_user:$mysql_pass - $dbid:" .
mysql_error() . "\n";
	fputs($file, $line);
	fclose($file);
        }
        return $dbid;
}

and here is what gets logged into /tmp/mysql-err:
/index.php:2003-05-05 14:30:53:db1.m-1.lan:public:secret - :Access
denied for user: 'public@10.10.12.254' (Using password: NO)

so function retrieves the password fine.

Thanks for the report.

Do you retrieve your password from any dynamic way or is it static?

We are currently using MySQL 4.0.12. This bug occurs occasionaly and
there is no way to guess what makes it appear. Even if there are
"hardcoded" username and password into the function, i.e. not passing
variables to it, like mysql_connect("mysql.host", "public", "secret"),
PHP reports Warning:

[05-May-2003 14:06:17] PHP Warning:  mysql_connect() [<a
href='http://www.php.net/function.mysql-connect'>function.mysql-connect</a>]:
Access denied for user: 'public@10.10.12.254' (Using password: NO) in
/var/www/sala.lt/htdocs/skundai/classes/db.php on line 10

So the problem is that warning (or mysql_error() message) about not
using password is not correct.
