RHEL 6.5 and Docker, Ruby Fixes and Epic Node.js Bugfixing – Snippets

Snippets.png

  • RHEL 6.5 docks?: Red Hat Enterprise Linux 6.5 has been released and as is usual for the point releases of RHEL, has a number of enhancements like Precision Time Protocol support (for microsecond synchronisation accuracy), better network data for admins, GlusterFS integration for KVM and NVMe (PCI SSD) support. Mentioned in the announcement is Docker, the container deployment platform, but oddly there appears to be no mention of it in the technical notes or release notes. LXC (Linux Containers) is also still on the Technology Preview list. Still, it’s a Red Hat update and the timer is now running for the equivalent CentOS, Scientific Linux and Oracle Linux updates to appear.

  • Ruby security update: There’s updates for Ruby 1.9.3 and Ruby 2.0.0 which both address a security problem, namely a heap overflow when parsing floating point numbers. The same issue is also fixed in the new preview2 of Ruby 2.1.0, just released.

  • Epic Node.js Bugfixing: There’s nothing like a good detailed walkthrough of the debugging hell someone’s been through to offer a chance to say (a) good work, (b) glad I didn’t have to do that and (c) you found what where? In the spirit of this, Joyent have documented the Walmart Node.js Memory Leak from identification to final elimination, in text and three video talks. The leak itself (in file closing) was subtle and the hunt hard – The fix is in the latest Node.js releases.
