Hacksgiving is over!

What it is

A logical extension of the Adopt a plugin work from Unknown User (danielbeck). Hacksgiving is a multiple day event to clean up deprecated plugins, merge plugins that make more sense to be merged into one, fix some bugs floating around in the issue tracker and of course have fun before the turkeys go in the oven (in the US).

This event is *open to everybody*. There's more to an open source community like Jenkins than the Java code. If you are interested in writing documentation, creating new demos or screenshots, or just learning a bit more about how the plugins and project are built, please join us!

No really

"Hacksgiving" is a made-up event around the time of Thanksgiving (in the US). In the past Unknown User (rtyler) has organized "Hacksgiving" events during the lulls in project schedules

When is it

Proposed time: November 23nd - November 24th

The current plan is to have an open virtual space via Google "Hangouts on Air", which would periodically have sessions from volunteers on the schedule. Similar to an unconference style event in "the real world."

How to Participate

  • Join the #jenkins IRC Channel on Freenode
  • Watch the #Hacker Hangout YouTube live stream or join the Hangout directly via Google Hangouts

Wanted Sessions

  • Introduction to the Jenkins plugin development tools (ideally using an existing plugin as a reference)
    • Writing tests for a Jenkins plugin
  • Extending the Workflow DSL or making a plugin "Workflow ready"
  • Triaging Jenkins when things go wrong (how to debug/identify problems)
  • Creating acceptance tests for Jenkins plugins

Documentation hacking

For those not interested in working on core or a plugin, we'll also be doing some documentation hacking! Cleaning up documentation for plugins that need some sprucing up, etc.

Who:

Plugin Hacking

Who:

Hacker Hangout

We'll have some sessions around or during Hacksgiving to do hands-on plugin-development tutorials and support would really help get more plugins merged or adopted. The idea is still very rough, but some sessions to introduce folks to hacking Jenkins plugins would probably help quite a bit!

Proposed plugins to merge

If you are interested in merging two plugins, please work that out with the respective plugin maintainers. We will not be forcing any two plugins to be merged together, but if two maintainers mutually agree to merge, Hacksgiving is a good time to do it!

If you add to this list, please leave your name so maintainers know who to contact.

Plugins to clean up

  • gitorious - gitorious is a dead site
  • one of groovy-events-listener-plugin-master and groovy-events-listener-plugin
  • gitlab-plugin - owenmehegan would like some help reviewing this code and making a roadmap for improvements
  • There are 430 plugins using a deprecated Jenkins api. You can see details for each plugin here. Perhaps, some PR could be submitted to fix some of these plugins ? (suggested by evernat)

Workflow session

All state and data inside of a Workflow script must be serializable which will allow Jenkins to serialize the Workflow to disk if Jenkins needs to restart, the workflows can be restarted.
rtyler to update docs to mention need for serializable interfaces on embedded classes

When using multibranch workflows you can specify branches to match against, otherwies the workflow will use all available branches which have a "Jenkinsfile" in them so it's expected that the "stale" (i.e. merged) branches
