Back to repository configuration

APEL-SSM 3.0.1

Secure STOMP Messenger (SSM) is designed to simply send messages using the STOMP protocol or via the ARGO Messaging Service (AMS). Messages are signed and may be encrypted during transit. Persistent queues should be used to guarantee delivery.

SSM is written in Python. Packages are available for RHEL 7 and Ubuntu Trusty.

The installation and configuration guide is available here:

Check also the EGI wiki for more information about APEL SSM.

Release notes:

  • As part of the migration to Python 3, this release removes support for Python 2.6.
  • The argo-ams-library is now an optional module, depending on whether the Argo Messaging Service is used or not.
  • Fixed how the use_ssl config option is retrieved to avoid "referenced before assignment" errors leading to SSM failing to run.
  • Changes made to messaging loops to avoid high CPU usage.

CVMFS 2.7.5 and egi-cvmfs-2-7.12

The CernVM File System provides a scalable, reliable and low-maintenance software distribution service. It was developed to assist High Energy Physics (HEP) collaborations to deploy software on the worldwide-distributed computing infrastructure used to run data processing applications. CernVM-FS is implemented as a POSIX read-only file system in user space (a FUSE module). Files and directories are hosted on standard web servers and mounted in the universal namespace /cvmfs.

Release notes

CernVM-FS 2.7.5 is a patch release. It contains bugfixes and improvements for Ubuntu clients and servers. Please see detailed release notes in the technical documentation.

dCache 5.2.35

dCache provides a system for storing and retrieving huge amounts of data, distributed among a large number of heterogeneous server nodes, under a single virtual filesystem tree with a variety of standard access methods.

Detailed release notes on the official product site:

DMLite/DPM 1.14.2

The Disk Pool Manager (DPM) is a lightweight storage solution for grid sites. It offers a simple way to create a disk-based grid storage element and supports relevant protocols (SRM, gridFTP, RFIO) for file management and access. It focus on manageability (ease of installation, configuration, low effort of maintenance), while providing all required functionality for a grid storage solution (support for multiple disk server nodes, different space types, multiple file replicas in disk pools)

N.B. the gridftp and http frontends are now build together with the dpm core, so they have new package names

  • lcgdm-dav -> dmlite-apache-httpd
  • dpm-dsi -> dmlite-dpm-dsi

as well as the xrootd frontend starting from v 1.12: dpm-xrootd -> dmlite-dpm-xrootd

Dynafed 1.6.0

The Dynamic Federations system allows to expose via HTTP and WebDAV a very fast dynamic name space, built on the fly by merging and caching (in memory) metadata items taken from a number of (remote) endpoints. More information.

STORM 1.11.19

The StoRM Product Team is pleased to announce the release of StoRM 1.11.19 that includes the following updated components:

This release mainly:

  • fixes a bug introduced with StoRM v1.11.18 about the final update of the status on database of a srmPtG or srmBoL requests;
  • introduces new metrics in storm-backend-metrics.log;
  • fixes a storm-webdav bug about the returned body content in case of HEAD requests.

Please, follow the upgrade instructions.

Read the release notes for more details.

VOMS 10-20 release

Please have a look at the release notes for more details.

xrootd 4.12.5 and 5.0.2

XRootD software framework is a fully generic suite for fast, low latency and scalable data access, which can serve natively any kind of data, organized as a hierarchical filesystem-like namespace, based on the concept of directory. As a general rule, particular emphasis has been put in the quality of the core software parts.
