Release Manager Process Notes

Component Release Manager Duties

Version Numbers

We use semantic versioning:

  • Major number bumps for incompatible changes (2.3.1 ==> 3.0.0)
  • Minor number bumps for new features (2.3.1 ==> 2.4.1)
  • Point number bumps for bugfixes (2.3.1 ==> 2.3.2)

NOTE: the version numbers of the different components in the Hydra stack (HydraHead, ActiveFedora, OM, Solrizer ...) are NOT synchronized.

Release Process

When to do a Release

  • to fix a bug
    otherwise, no more often than once a week
  • when a new feature is needed by a non-committer (someone who wouldn't want to pull from trunk)
    bigger releases (e.g. not backwards compatible) should not occur more often than once a quarter.

Responsibilities for Each Component's Release Manager

Barest minimum:

  • participate in Hydra Committers calls
  • ensure pull requests are dealt with in a timely fashion (a few days at most)
    • they must have tests
    • code authors MUST have an iCLA in place (or a cCLA from their institution) before any code is committed on their behalf.  See: /wiki/spaces/samvera/pages/405211654.  If no CLA exists, liaise with CLA manager to get one.
  • do releases as indicated.
  • Continuous Integration builds
    • if they break, ensure that they are fixed in a timely fashion
    • get rid of warning messages if possible (e.g. invalid YARD tag)
  • Tests
    • must run cleanly for component
    • full Hydra stack tests must run cleanly.
    • make sure bugs aren't just fixed, they're tested

What we really want:

  • track dependencies and schedules of other components as needed for synchronization
    • This is especially crucial for the HydraHead component manager
  • Tests
    • must meet target percentage for test coverage
  • Responsible for Inclusion/Exclusion of Code Changes
  • Contributions from non-committers must be evaluated in a timely fashion
  • Ensure contributors have CLA on file (contributor license agreement)
  • Code Changes must
    • have test coverage
      • run cleanly for component, and change does not break full Hydra stack tests.
    • have documentation coverage (also yard/rdoc must cleanly compile - see above re API docs)
    • behave correctly
    • have readable code
  • Creating a Release
    • Release Notes
      • must indicate the full release number, the date, and what has changed since the last release.
        • Github tickets and possibly git history are best ways to find this information
      • put into HISTORY.textile which is symlinked to RELEASE_NOTES; both in root directory of component.
    • tag in git?
      • send email to hydra-tech indicating the new release, its number, and what has changed. Send an email once a week (if there is a release that week)
    • for MAJOR and MINOR releases, send an email to the list with the release notes.
    • for MAJOR RELEASES, provide details on release to Web Site Manager / Steering Group sufficient to generate a Press Release.
    • for MAJOR RELEASES, document upgrade path
  • Find and train your successor Component Lead
  • Support your successor component lead w/ tying up any loose ends

Web Site Manager Housekeeping Responsibilities

  • overall maintenance of website
    • ensure a steady stream of news
    • provide notification of major software releases
    • maintain up to date information about partners and projects
    • periodically review site for outdated and/or inaccurate content
  • regular patching of WordPress site to latest version (directly, or by liasing with Web site designated technical support)
  • News
    • keep an ear to the ground for information that should become news (steering and partner call, lists, etc)
    • write up and post news (chasing content from individuals where necessary)
    • follow up news if it should become or affect page content
    • try to ensure a steady flow (at least something new each month)
  • Software releases
    • Liaise with colleagues to provide web content around software releases (see above)
  • Partners and projects
    • In collaboration with partners, ensure that all partners and formally announced projects are properly represented on the site
    • Ensure that pages containing information about partners and projects are kept up to date
    • Create new pages for partners and projects as appropriate (chasing individuals for information where necessary)
  • Content
    • add new content when available (posts and pages), maintain menus as required
    • periodically review site for outdated or inaccurate content: liaise, as appropriate, to update, change or delete such
    • notify significant changes to the appropriate Hydra lists
    • regular full exports from WordPress as backup (after any significant change)

Committers Call Housekeeping Responsibilities

  • prepare weekly agenda
    • in wiki:
    • send email prior to meeting (preferably on Friday, or at least before Monday morning Pacific time) with weekly agenda inline
    • topics culled from
      • hydra-tech email since last call
      • IRC
      • JIRA
      • any leftover agenda items from previous call
      • any relevant items from other related meetings (hydra partners, combined blacklight/hydra committers calls ...)
    • always included:
      • call for items
      • schedule next call
        • choose next moderator
        • choose next notetaker
        • choose next JIRA wrangler (optional)
      • JIRA roundup for sprint ending on day of call
  • JIRA
    • this is currently done by one Jira groomer for all components.
    • BEFORE call:
      • create JIRA version in HYDRA project for next weekly sprint
        • try to maintain an appropriate order for the versions
      • look at previous un-released sprints (before the one ending on day of call)
        • ensure all tickets are resolved and/or closed (you may need to move some or ask people or what-have-you)
        • do a JIRA "release": from manage versions, when you hover over version, on far right is setup wheel - one of the menu items is "release".
    • note that there are JIRA versions for the components and their releases: these are used in addition to the versions for the weekly sprint, and are not part of the Committers Call Housekeeping Responsibilities

tech documentation

  • ensure the documentation for creating a hydra application from scratch is excellent
  • ensure it is easy for folks to find the documentation they seek
  • watch for questions on the hydra-tech list, and ensure the documentation reflects the information desired
  • organized for sane newbie access
  • invite newbies to smoke test installs, provide feedback to enhance docs and process
  • keep track of what upgrade problems people are having and update the upgrade notes with that information
