WTP PMC Defect Review

As the end of a release cycle nears, WTP needs to add some governance in order to maintain stability and quality in the face of the upcoming deadline. To this end, a PMC review process will occur.

Important Note - The PMC Review is not an in depth technical accuracy review, but a general risk management analysis of possible benefits and associated risks of including a proposed fix.


How To Prepare a PMC Defect Candidate

The answers to the following bullets must be incorporated into the bugzilla entry before a defect will be considered for PMC approval:

  • Explain why you believe this is a stop-ship defect. Or, if it is a "hotbug" (requested by an adopter) please document it as such.
  • Is there a work-around? If so, why do you believe the work-around is insufficient?
  • How has the fix been tested? Is there a test case attached to the bugzilla record? Has a JUnit Test been added?
  • Give a brief technical overview. Who has reviewed this fix?
  • What is the risk associated with this fix?

How To Get a PMC Defect Fix Candidate Approved

Overview of Steps Required:

  • Developer fixes defect and attaches fix patch to the defect.
  • Developer also adds documentation about the fix and why it is a must fix.
  • Developer asks for component lead review and the component lead (or delegate) documents their review and approval.
  • Component lead then:
  • Puts "PMC" in the Status Whiteboard field.
  • Adds hjzhang@ca.ibm.com as a CC to the bug.
  • Adds the following to the pmc_approved flag with a "?". You can copy/paste the whole line in one field.
david_williams@us.ibm.com, raghunathan.srinivasan@oracle.com, naci.dai@eteration.com, deboer@ca.ibm.com, neil.hauge@oracle.com, kaloyan.raev@sap.com
This will add PMC approval flags for each PMC member and automatically send the PMC member an email.
  • PMC members review and vote. A single negative vote will reject a defect and usually a minimum of two positive votes is required for approval. It will be incumbent on the PMC to do anything possible to perform reviews within 24 hours. To see if a bug is approved, the developer can watch the associated PMC approval PHP page, which will be dynamically updated.
  • If approval is given, the developer may then release the code (tag with version and update map files) for a build.
  • If the component lead does not get 24 hour turnaround on approvals, they should send a note to wtp-releng@eclipse.org with a link to the defect. (You must be a member of this list to send mail to it.)

PMC Members, How to vote

  • Instead of using a "+1" comment, you update the "pmc_approved" flag for your email address with a "+" for approve and a "-" for reject. The PMC summary web pages are updated to ONLY look at the flags and not text comments.
  • Note that it is the votes (and number of votes) that determines if/when a fix is "approved". Eventually, as an administrative task, the white board status field will be changed from 'PMC' to 'PMC_approved'. It is important to have this field up to date when increasing the 'number of votes' required for approval, or else the summary page may start to show previously approved fixes as still needing more votes.

Q & A

  • Q: Does Junit changes require PMC approval as well?
  • A: Committers can release Junit changes without waiting for approval, however the bug should still be marked for PMC review as usual. This so so everyone would be informed of the changes in case if it caused a build break or if teams are wondering why a build was kicked off when no changes were released.
