ZendFramework dependencies

[robocoder]

The latest version of Zend Framework has more dependencies than the 1.0-ish version of the library that Piwik previously used, e.g.,

• Zend_Validate_Hostname - iconv
• Zend_Feed - dom (part of php core, but may be packaged separately by the distro)

In [1554], fixes #1031 - ZendFramework dependencies

Do we use Zend_Validate_Hostname? I don't remember where. It seems a bit risky to add the iconv requirement to Piwik - I know that many web hosts didn't have it installed a few years back. If it is easy/reasonnable, it would be nice to not use Zend_Validate_Hostname and remove Piwik dependancy on iconv.

It was reported in the forum and also mentioned in the freebsd ports commit log.

I don't see an easy fix for this, unless you want to disable the ExampleRssWidget plugin.

In [1576], matt removed DOM because he got the error:

Undefined index: dom 
in '/mnt/var/www/html/tmp/templates_c/%%6262A62A24D1F%%systemCheck.tpl.php' at the line 119

I've added "extension" to #60
