Remove obsolete Pear plugins library

[Robert Lyon]

Keeping plugins up to date.

I note there is a xmlparser.php included in this - maybe we don't need the other xmlparser anymore?

We probably should look for a better non PEAR option for the libraries that rely on PEAR, eg Pear/XML, PEAR/Archive, PEAR/Log

[Robert Lyon (robertl-9)]

Sonn,
Hmm, I thought I'd written up my findings somewhere but I can seem to find it now.

But the gist of what I was thinking is this:

1) For dropping PEAR/XML, which looks to be used for the xml_feed_parser on RSS feeds, we could try using PHP in-built XML_Parser / XMLREADER or similar

2) For dropping PEAR/Archive/Tar we could just make an executive decision and drop the ability to extract .tar/.tar.gz archives in the Files page, as I suspect very few people use this functionality.

As most systems now have some in-built form of zip/unzip available we could just alert them with a message saying if they want to extract the files from the archive they will need to add it as a valid .zip format. Or not even bother and just have some mention of it in the Mahara manual.

3) For dropping PEAR/Log - not sure for this but it would be good to find out what it is logging and why that is different to error_log/log_debug. It might be simply we can use one of those to achieve the same result.

1) I will use PHP XML library (http://www.php.net/xml) to replace the PEAR::XML_Feed_Parser
I created a new bug for this https://bugs.launchpad.net/mahara/+bug/1594615

[Son Nguyen (ngson2000)]

PEAR/Log is only used in FeedReader and Tar. We can remove it after replacing 1 and 2

[Robert Lyon (robertl-9)]

Now that we have updated the xml parser and archive extraction to non Pear libraries we can remove the /lib/pear/ directory
