MPU Meeting Wednesday 22nd November 2017

Inventory

No activity since the last meeting.

LCFG Client Refactoring

Stephen has been tidying up odds and ends:

  • The generation of man pages from pod source has been fixed.
  • A new feature was added to Build Tools: the version number can now optionally be saved to a text file in the project directory when the project is tagged. It can then be retrieved by CMake at build time.
  • om, lcfg-authorize and lcfg-sysinfo now use the new resources module (LCFG::Client::Resources) instead of the old one (LCFG::Resources).
  • lcfg-om has been improved:
    • It now canonicalises hostnames and handles IPv6 properly.
    • Bug:983 (Deprecated use of oom adjustments at SL7 bootup) was fixed.
    • It's now more platform independent - for instance it now works in macOS.
    • Security checks have been tightened up somewhat.
    • Most of the code has been moved to a module in order to make it more testable at build time.
  • Kenny has been testing the new code, and his tests uncovered a problem whereby some components had resources which had been inappropriately been declared to be tag lists. Stephen has blogged about this (LCFG Core: resource types) and has created Bug:1016 and Bug:1017.
  • Some testing is still to be done. In particular, when qxprof produces output that's intended to be evaluated by the shell, the old and new versions of that output should be tested to ensure that they're the same.
The code is still on course to be deployed to the develop release at the start of December.

Miscellaneous Development

Chris has made a Virtual DICE image for Alastair to test, to see if it solves the Windows 10 login problem.

Operational

  • We're looking for copies of the v5 NoMachine client installer, particularly one for the Mac.
  • Stephen has sorted out the OpenAFS build hosts. The mock version had changed, and configuration changes were needed to enable it to continue to support SL6.
  • Stephen has made a first pass through the Requested Software queue and has spotted some likely-looking candidates for installation. He will produce and document a process for adding software.
  • We've been tackling our computing.help page reviews. Chris will review 'troubleshooting virtual dice' and 'setting a default application on dice'.
  • Alastair will take RT:73120.
