Hello,


I just downloaded and installed the cvs version. It works on my local
system, but it doesn't on the remote host. I checked dozens of time the
settings.php password, db, etc...
Drupal 4.6 works perfectly at the same host, using the same data base,
same user, same password (different prefix only, and different
url/domain).


I get an empty string as sql error message:
The MySQL error was: .


"Are you sure you have the correct username and password?


"
Yes. the same as existing drupal 4.6 install.


"Are you sure that you have typed the correct hostname?


"
Yes. idem.


"Are you sure that the database server is running?


"
Yes. working  for other installation.


To check that the settings.php was properly uploaded, I changed the
username in settings.php and uploaded again: the name changed in the
mention at the bottom of the new error page, but the mysql error is
still an empty string.


I do have a mysql error message if I change the username on my
localhost:
The MySQL error was: Access denied for user: 'testerror at localhost'
(Using password: YES).
Currently, the username is testerror and the database server is
localhost.

If I suppress the @ I have the following error message:


Warning: Wrong parameter count for mysql_connect() in 
.../includes/database.mysql.inc on line 37


which seems strange in this context.
I have a - in the database host: out-data.org. Would that affect the
parsing of the variable in settings.php?

It's definitely a php problem, not mysql settings:
we use PHP Version 4.2.3


by replacing the line:

<?php
$connection = @mysql_connect($url['host'], $url['user'], $url['pass'], TRUE, 2);
?>


by its values:

<?php
$connection = mysql_connect('data.out-data.org', 'user', 'pass', TRUE, 2);
?>




I still get the Wrong parameter count for mysql_connect() message...


???


4.6 works fine on the same host.

Drupal 4.6:

<?php
  $connection = mysql_connect($url['host'], $url['user'], $url['pass'], TRUE) or die(mysql_error());
?>




Drupal cvs:

<?php
$connection = @mysql_connect($url['host'], $url['user'], $url['pass'], TRUE, 2);
?>




One more parameter has been added.


php.net/mysql_connect :
php 4.3.0   Added the client_flags parameter.


i.e. cvs Drupal and the coming 4.7 version will not work for php
versions < 4.3.0. My hosts unfortunately uses 4.2.3.

I've seen that the list of requirements states php > 4.3.0, but I guess
I won't be the only one to be surprised to see that drupal doesn't work
AT ALL (no DB connection) when they upgrade.


Yet, by modifying the line above, to make it look like version 4.6, I
am able to use drupal cvs on my server with an older php version (I'm
on the lookout for other similar bugs).


I was trying to add a if loop, checking on the php version used, so
that we have:



<?php
if ($php_version >= 4.3.0){
  $connection = @mysql_connect($url['host'], $url['user'], $url['pass'], TRUE, 2);
}else{
  $connection = mysql_connect($url['host'], $url['user'], $url['pass'], TRUE) or die(mysql_error());
}
?>




but I cannot find in the documentation how this variable can be tested.


Also, once connected to the data base, a warning in admin/settings can
be added about the php version used.


Or do you really mean to shut out all the people who depend on the
(lack of) will of their host to upgrade php? If so, at the very least,
add a list item in the error message to remind people to check for the
php version.
