DPM 1.9.0 - EPEL-testing release of the core components

Hello,

we just pushed the latest versions of the core components of DPM to EPEL-testing. These
should be already available in the repositories, or will appear in the various
mirrors in the next one or two days. We encourage sysadmins to test this release and give
feedback before it's promoted to the EPEL stable repository.

This is an important release that keeps the compatibility with the past while adding
many features. What follows are the highlights and the release notes.

Cheers
Fabrizio Furano, on behalf of the DPM team

=======================
============ Highlights

First internal release of DOME, the REST core for DPM
When using domeadapter dpm,dpns,libshift,rfio,CSec,SRM become optional
DMLite API improvements (C and C++) for dealing with space reporting
Performance improvement in uploading small files
All components passed to boost 1.48 (fixes a few nasty bugs in boost)
Report available bytes as per rfc4331
Tons of additions to dmlite-shell (including space reporting and DPM config)
Great functional test program dpm-tester
Now dmlite also produces the DPM metapackages (into EPEL). No need for external repos anymore for metapackages
Good interplay DOME vs legacy LCGDM on space reporting
Implement volatile filesystems and file pulling in DOME
No more crazy libgridsite session files using HTTPs
