Bug #3186: require not working as expected
http://projects.reductivelabs.com/issues/3186
Author: Dan Bode
Status: Unreviewed
Priority: Normal
Assigned to:
Category: plumbing
Target version:
Affected version: 0.25.4
Keywords: require order
Branch:
I have an example where require is not correctly specifying a dependency
between classes.
<pre>
$mysql_old_pw='b'
$mysql_root_pw='p'
$redmine_db='r'
$redmine_db_user='red'
$redmine_db_pw='red'
include redmine::mysql
</pre>
<pre>
class redmine::mysql {
require mysql::server
require mysql::ruby
if ! $redmine_db {
fail('$redmine_db parameter is required')
}
if ! $redmine_db_user {
fail('$redmine_db_user parameter is required')
}
if ! $redmine_db_pw {
fail('$redmine_db_pw parameter is required')
}
database{$redmine_db:
ensure => present,
charset => 'utf8',
provider => 'mysql',
}
database_user{"${redmine_db_us...@localhost":
ensure => present,
password_hash => mysql_password($redmine_db_pw),
require => Database[$redmine_db],
provider => 'mysql',
}
database_grant{"${redmine_...@localhost/${redmine_db}":
# privileges => [ 'alter_priv', 'insert_priv', 'select_priv', 'update_priv'
],
provider => 'mysql',
privileges => all,
}
}
</pre>
<pre>
class mysql::server {
# set the mysql root password
if(! $mysql_root_pw) {
fail('$mysql_root_pw must be set for class mysql::server')
}
package{'mysql-server':
name => 'mysql-server',
ensure => installed,
notify => Service['mysqld'],
}
.....
#more code here
</pre>
the require statement should order all of the resources in mysql::server before
everything in redmine::mysql, but the Database resource is applied before the
mysql-server package is installed (see output below).
<pre>

</pre>
I can work around by specifying require=>Class['mysql::server'] for the
resources that care about order, but I would rather use require.
