[EP-tech] Re: Eprints 3.1 to 3.3 upgrade not working



Hi all,

As previously mentioned I have gone into the aforementioned http://trac.eprints.org/eprints/browser/tags/3.3.7/system/perl_lib/EPrints/Plugin/Convert and have opened each file to ensure the content is the same as the one I have in 3.3.10. I do not see any difference in the convertors and the installation copy is brand new with no edits (although the database, documents and phrases have been changed with the old 3.1 ready for upgrade).

I am unsure as to whether or not it's possible the 3.3.10 Debian version of EPrints is missing files compared to the older versions of 3.3? I have noticed from a Debian direct installation of 3.3.10 the basic search gives an internal server error which then later can be seen as a file not found at /eprints3/archives/name/var/xapian in the apache logs. I am not sure if this could also be connected to any changes which are not reflected in the latest epadmin process.

What I did notice is that if I try upgrading EPrints 3.1 to 3.2.4 via a 3.3 installation it gives many different errors compared to the successful result of doing the same process with 3.1 to 3.2 with a 3.2 installation, which confused me as I thought the epadmin upgrade process from 3.1 to 3.2.4 would be the same in both the 3.2 version and 3.3 version and it would only be extended beyond 3.2.4 to the newer versions of 3.3? i.e. 3.3.6 to 3.3.10

If anyone has any ideas or has had these problems please could you let me know how you managed to fix it? 

Thanks everyone,

Kind regards,

David Whitehead.

Hi Tim,

Thanks for getting back to me, As I have installed EPrints into the /usr/ I have looked into /usr/share/eprints3/perl_lib/EPrints/Plugin/Convert and there are 4 pm files. Below is there last modified dates, DocPDF.pm - Last modified 29/05/2012 IndexCodes.pm - Last modified 29/05/2012 PlainText.pm - Last modified 29/05/2012 Thumbnails.pm - Last modified 29/05/2012



I am unsure as to why I would be using an older convertor as all I have done is install a brand new version of eprints 3.3.10. I then copied only version of the "Documents" folder in the archives and Redid the archive database with the same name but made from the 3.2.4 sql backup that I made after upgrading from 3.1 to 3.2.4. 

On another side note though I did also notice that the simple search Xapian is also not working in 3.3.10 "even freshly installed with no modifications yet to EPrints" every time you try and do a basic search you go to internal server error page, the error in the apache log is "Exception: /usr/share/eprints3/archives/"name"/var/xapian". When navigating to the var folder I find nothing their other than one timestamp method. Just thought you might want to know,

I installed EPrints 3.3 on Ubuntu via package manage "apt-get install" after adding "deb http://deb.eprints.org/3.3/ stable/" and "deb-src http://deb.eprints.org/3.3/ source/" to sources.list

I hope this information is of some use to you, if you need anything else just let me know and thanks again for getting back to me,

Kind regards,

David Whitehead.

Hi,

It looks like the text isn't being extracted from a PDF and, rather than the PDF convert plugin gracefully returning, it trips a file missing check in Convert::IndexCodes.

Can you compare your set of Convert plugins with:
http://trac.eprints.org/eprints/browser/tags/3.3.7/system/perl_lib/EPrints/Plugin/Convert

It doesn't look like you should get to the problem you have, so I'm wondering if you have an old PDF text extraction plugin that's getting in the way (instead of Convert::DocPDF and the 'antiwordpdf' utility).
