DSDP  -  Mobile Tools for Java   (MTJ)   Bug Process

This documents how the Mobile Tools for JavaTM (MTJ) Project uses Bugzilla to handle bug reports, enhancement requests, patches etc. It covers basic lifecycle information and clarifications for how to use the various Bugzilla fields.

Bug Lifecycle

Everybody - users and developers - may apply for a Bugzilla account and submit bug reports or enhancement requests.

Once the bug report is filed, contributors and committers work on it, including updates to bug status. All users may contribute to the discussion by adding comments (but typically not change the status fields). The Eclipse Process Guidelines contain some good information and a handy diagram for understanding the lifecycle of an issue in Bugzilla.

How to defer bugs

The main goal of these guidelines is to be able and write good bugzilla queries that allow us avoid looking at deferred bugs again later. So here is the process:

  • Set the Priority according to personal judgement of importance: Even bugs with a high priority can be deferred to an upcoming release if time just dont permit fixing them.
  • Set Resolved, Resolution=INVALID for requests that do not make sense.
  • Set Resolved, Resolution=WONTFIX for bugs that we will supposedly never address e.g. because there is a suitable workaround or the effort is just too high although the request makes sense.
  • Set Target Milestone=Future for bugs that make sense but are too much effort for the current release. They should be triaged again for the next release, and perhaps be documented as known limitations in the release notes. Such bugs will typically be in NEW state and assigned to
  • Assign the bug to a developer and set the target milestone for bugs that we want to address in the current release cycle.
  • Assign bugs to the with the default target milestone="---" if you have no idea what to do with a request and also dont know who else could handle it. It will triaged again by all committers together in the next committer meeting. Please do this as a last resort, though, since looking multiple times at the same bug is unnecessary effort; and add a comment with your thoughts on the bug.

How to verify and close

  • Bugs that are set RESOLVED are candidates for verification.
  • Ideally, the person who filed a bug should also verify it and set it to VERIFIED if OK.
  • During the final release test cycle, all RESOLVED and even VERIFIED bugs will be checked again. If they pass the test, they will be set CLOSED.
  • Enhancement requests and applied patches can also be set CLOSED right after checkin, especially if they do not apply to testable product functionality but rather some code cleanliness.

Clarification of Fields

  • Platform and OS: These should be set by the submitter of a bug to describe the platform and OS on which a bug was detected. This does not mean that the bug would occur only on this particular platform.
    • Use Platform All only if you have good evidence that a bug actually occurs on all platforms.
    • When you are sure that a bug occurs only on a particular platform, please indicate so in the Summary field by adding a tag lice [mac] or [linux]

Submitting a Patch

Every user may submit a patch for an issue he finds, by attaching the code to the corresponding Bugzilla item. Submitting patches turns the ordinary user into a contributor, for which he or she will be given credit to.
Please attach only patches on bugzilla for which you have the right to attach them. In the typical case, if you put a legal notice like the following alongside your contribution, it will speed up the contribution process:

Legal Message: I, {name}, declare that I developed attached code from scratch, without referencing any 3rd party materials except material licensed under the EPL. {I am authorized by my employer to make this contribution under the EPL.}

If this message does not apply for you (e.g. because you did use 3rd party materials), please contact the Developer Mailing List to seek assistance of a committer.
Once your contribution is attached to Bugzilla, a committer will pick it up and follow the committer guidelines to merge your contribution.

Best Practices

  • Before reporting a bug, please read the bug writing guidelines.

Watch the user for new bugs

You need to use the Bugzilla "watch user" feature to receive notifications from this list. Below are the steps to configure your Bugzilla account properly:

  1. Login to Bugzilla and select the "preferences" link.
  2. Once there click the "email preferences" tab.
  3. Put in the "Add users to my watch list" text box at the bottom and click the submit button.

The user was set as the default contact for all components/products from the MTJ and anytime someone posts a bug against those we will be notified.
