Hi Seb and all,

thank you Seb for the great support you donated us in these years. With you the eprints support has improved very much.
I wish you a great new job, interesting and full of opportunities.

Best regards,

I'm moving a repo...
... from Solaris containers to Virtual Machines running Redhat Centos ... from Perl 5.10.1 to Perl 5.20

Everything seemed fine, until I started testing the SWORD conenctions - and I was getting errors!

Checking in a web broswer, normal pages are fine: I can browse and surf with no issues... but when I try to get a "servicedocument" I get

EPrints System Error

Can't copy /home/eprints/ePrints/archives/eprints1/cfg/static to
/home/eprints/ePrints/archives/eprints1/html/en: Is a directory

Turns out that EPrints::Utils::copy uses File::Copy::copy - and File::Copy::copy has undefined behaviour when copying 1 directory to another.... and it was broken with this new configuration!

I installed File::Copy::Recursive and edited EPrints::Utils::copy to use it.... and "happy days!"
(use File::Copy::Recursive::rcopy - its smart and will do File::Copy::copy or File::Copy::Recursive::dircopy as appropriate)


So - a potential bug for future installations, and something I need to remember to check when I upgrade to 3.3.12 :)

Thank you both, Yuri and Paolo. :-)

I am afraid, though, that this is not quite a sustainable, scalable approach. If for instance one used Recollect Plugin or whatever, anyway EPrints as a research data store, even bigger files would be to serve, say hundred gigabyte large database dumps. EPrints could not handle that giant files this way, as it would need absurd *several hundred* gigabyte of RAM and swap, let alone other involved bottle-necks in the program flow. If you don't mind my assuming that in regard to its easygoing use of join("", <STDIN>).

Concerning large files, we thought we could serve files up to a maximum of a DVD image. For the time being I will prefer the described copy & hack database method (but as said, I'll try use the API next time).

Look, as a public university library it is not overwhelming hardware resources which we have got for the given purpose, so we must use wise and economically what is available.


Kind regards
Florian
