Submission + - Second Beta of Linux DTrace Arrives

mvar writes: From the H:
Oracle has released a second beta version of "DTrace for Oracle Linux". The Linux port of the tracing software that was originally developed for Solaris now implements a provider for SDT (Statically Defined Tracing), providing in-kernel static probes; the developers say that they have also fixed a number of bugs.
This version of DTrace (Dynamic Tracing Facility) requires the Linux 2.6.39-based version 2 of Oracle's "Unbreakable Enterprise Kernel", which is due to be part of Oracle Linux 6 and is currently still in its beta phase.

Submission + - Oracle to bring Dtrace on Linux

mvar writes: Dtrace co-author Adam Leventhal writes on his blog about Dtrace for Linux:

Yesterday (October 4, 2011) Oracle made the surprising announcement that they would be porting some key Solaris features, DTrace and Zones, to Oracle Enterprise Linux. As one of the original authors, the news about DTrace was particularly interesting to me, so I started digging.
Even among Oracle employees, there’s uncertainty about what was announced. Ed Screven gave us just a couple of bullet points in his keynote; Sergio Leunissen, the product manager for OEL, didn’t have further details in his OpenWorld talk beyond it being a beta of limited functionality; and the entire Solaris team seemed completely taken by surprise.
Leunissen stated that only the kernel components of DTrace are part of the port. It’s unclear whether that means just fbt or includes sdt and the related providers. It sounds certain, though, that it won’t pass the DTrace test suite which is the deciding criterion between a DTrace port and some sort of work in progress.

Submission + - Red Hat Changes Source Code Shipping Method (h-online.com)

mvar writes: Red Hat has changed the way it ships the source code for the Linux kernel. Previously, it was released as a standard kernel with a collection of patches which could be applied to create the source code of the kernel Red Hat used. Now though, the company ships a tarball of the source code with the patches already applied. This change, noted by Maxillian Attems and LWN.net, appears to be aimed at Oracle, who like others, repackage Red Hat's source as the basis for its Unbreakable Linux. Although targeted at Oracle, the changes will make work harder for distributions such as CentOS, the community built Linux distribution also based on Red Hat's sources.

Submission + - Oracle May Remove JUnit from NetBeans (h-online.com)

mvar writes: On behalf of about 800,000 active users, the platform architect of the NetBeans Java development environment, Jaroslav Tulach, has called on the developers of the popular JUnit test tool to place their Java technology under a more contemporary open source licence. In his posting in the test tool's Yahoo group, Tulach writes that JUnit's current Common Public License (CPL) is "sort of archaic", and that he doesn't know of any other similarly popular project still using this licence. As an alternative, Tulach suggests using either the Eclipse Public Licence (EPL), which is largely compatible with the CPL, or offering JUnit under a dual licence (EPL, CPL).
