Version

This field represents the version of the Yocto Project for which the bug applies. The list of versions can vary depending on the Classification, Component and Project. The list also contains versions of the Yocto Project that are currently being developed.

Here is a sample list of selections at given the last time this wiki page was updated:

Target Milestone

This field represents the Yocto Project release milestone the assignee of the bug estimates the bug will be fixed. The values are based on releases and Milestone numbers. For example, "2.4 M4" indicates the fourth milestone for the 2.4 release.

Importance

The Importance of the bug is defined by its Priority and Severity. The Priority classifies the bug's fixing order. In other words, how soon will it get fixed relative to other bugs? Priorities are set during the bug Triage meeting and cannot be changed by the user. The priority appears to the left of the Severity field. Here are the values that Priority can be set to during the Triage meeting:

  • High -- Bug fixing is planned immediately for the target milestone. Milestone cannot be released if there is a high bug opened against the milestone. High priority issues cause major functional loss of a specific feature that is POR for the up-comping milestone. These issues are easily hit by the user and greatly impact the user experience or customer requirements. Finally, these issues could be urgent security fixes that need to be corrected in a prior release. The bug assignee is not to change the target milestones for High bugs without prior approval of the Triage team.
  • Medium+ -- Bug fixing is planned before the milestone and must be fixed or have a solution planned before the release is finalized. These issues are not show-stoppers but have somewhat significant impact to system functions and user experience.
  • Medium -- These are important issues we keep track and try to plan fixing for the release. They have limited impact for the system functions and releases.
  • Low -- Bug fixing is only done opportunistically. Generally not planned for the up-coming project release. Issues that are not a POR feature request, or are hard to reproduce fall into this category.
  • Undecided -- These issues are newly reported and are undecided before Triage. Issues that are a feature request, which isn't approved for future release yet. This issue will be changed to have an actual Priority after the Triage team approves it.

Note: High impact but Low Priority bugs can be documented in the release notes.

The Severity indicates how much the issue impacted the person reporting the bug. Severity can be categorized into five areas.

  • Critical -- Crashes, hang, loss of data, negative impact to other components, memory leak etc.
  • Major -- Major loss of functionality of POR.
  • Normal -- Regular issue, some loss of functionality under certain circumstance. This is the default Severity.
  • Minor -- Minor loss of functionality, or issues with easy workaround available.
  • Enhancement -- Request for enhancement or new feature to be worked.

Bug Status

  • NEW -- A new reported bug with default assignee.
  • ACCEPTED-- The assigned developer has reviewed and accept the bug.
  • RESOLVED -- bug is fixed or closed by other resolved method.
    • FIXED -- This is fixed and in the master branch will be set automatically during build
    • NOTABUG -- This is verified as not a bug
    • WONTFIX -- We will not fix this bug, possibly because a newer package fixes it.
    • DUPLICATE -- Duplicate of another bug, possibly different failure mode
    • INVALID -- The bug is invalid, sometimes this is used when the author of the bug does not provide accurate information, these will be reviewed by Triage team, and could be changed to NEEDINFO or it is not a feature of Yocto Project to fix.
    • OBSOLETE -- The bug is obsolete, old bug that is no longer appropriate, or a package that is depercated.
    • WORKSFORME -- The bug does not appear when tested by engineer, more appropriately, this may be NEEDINFO
  • VERIFIED -- bug is double checked and agreed with the resolved method by original reporter.
  • REOPENED: bug can be reopened, if it is in Resolved, Verified or Close stage.
  • NEEDINFO: bug needs further information from someone in order to make progress on the bug. Whoever set a bug to NEEDINFO should also change the assignee to who they are requesting the information from.
  • WAITFORUPSTREAM: The owner does bug analysis and finds this bug comes from upstream. Owner can post a new bug in upstream bugzilla, change status to WAITFORUPSTREAM and add the upstream bugzilla URL in comment area. When upstream bug is fixed, put the bug fixing into Yocto repository. After the patch is built into weekly build, change its status to RESOLVED/FIXED.
  • CLOSED stage is not used in normal bug life. When reported two same bugs by wrongly click button twice, the 2nd one can be closed. Generally it (close stage) is just for keeping wrong bug out of scrub cycle and statistic.

Bug Life Cycle

A normal Bug's life is starts from NEW and ends with VERIFIED. Triage team will select "verified: Program Management", after confirm the verification.

Bug Life Cycle

Bug should be marked as RESOLVED/FIXED, after its fixing patch is built into formal build (weekly build or milestone build). There is an automatic method to update bugs to RESOVLED/FIXED status by following steps.

  1. Developer fixed bug and check in patch to his contrib branch with special words in commit description (e.g. [YOCTO #4321])
  2. Developer asked tree gatekeeper to pull patch.
  3. Release Engineer do formal build. The build script will read new commit description and find out bug ID.
  4. Build script will notify bugzilla and update bugs status to RESOLVE/FIXED

If a weekly build includes a new commit, which reverts another patch, there should be a tool to judge whether the reverted patch summary include any bug fixing ID. If the reverted patch does include any bug fixing, the bug should be reopened.

Bug Fixing Process

Submitting and Owning a Defect

Anyone working with Yocto who has a Bugzilla account can enter a defect. Bug submission should include severity, thorough environment information, proper and clear reproduce steps and logs.

Bug Submitter

When you submit (open) a bug, be sure to do the following:

  1. Provide a clear and simple bug subject. It is recommended to put a Fault Component Name with brackets at the beginning of subject as a keyword, e.g. [Poky].
  2. Validate all fields are correct. If fields are not filled out correctly, the bug might be sent back to the submitter.
  3. Judge and select the appropriate Severity.
  4. Add any additional information from the bug scrub.
  5. Assign the bug to the correct person to disposition the bug.
  6. If a bug is too vague to make a determination, then the Resolution Field of the bug will be set to NEEDINFO and sent back the bug submitter.
  7. Make sure you edit the CC list to include other people you might think should know about the defect.
  8. Set the "Documentation change" field appropriately. This field helps the people that create and maintain the Yocto Project manuals by alerting them to a documentation need for the defect's resolution.

NOTE: You cannot set a defect's Priority when you submit a bug. The Priority is set during the Bug Triage.

Bug Owner

If you are the owner of a bug, be sure to do the following:

  1. Review your bugs to check if there is enough information. If not, set the bug to NEEDINFO.
  2. Try to reproduce your bugs when clear steps exist in the bug's description.
  3. Address bugs based on their Priority and Severity. For example, High Priority bugs usually should be fixed in 2 weeks. High/critical bugs should be fixed as soon as possible, which impacts the whole system.
  4. Be timely regarding updating bugs with comments. Timely comments both helps those working on the bug and keeps a bug active. Set the bug to FIXED and provide the tree/commit information once the bug is fixed. You should not mark a bug as RESOLVED/FIXED, if the patch is not checked into the repository.

Bug Tracking

Yocto spans many geographies. A single bug scrub meeting is not easy to maintain. Because Yocto Project is a large, active project, a Triage is used to effectively disposition bugs. The Bug Triage team reviews a bug's severity, features, and schedule to best facilitate a bug's resolution. Triage team will set new bug priorities, correct ownership for the work to be done, and insuring an appropriate target milestone for the bug. Triage process is documented at Bug_Triage

Feature Request Process

New feature request should be applied through Bugzilla as a bug. User should set the Severity to Enhancement. The request will be triaged in the Triage Team meetings.

There will be two important feature request review time per year in March and September (2 months before final release). In the review period, there will be 2~4 times review meetings by the triage team. The Triage team will which decide new features which will be included in next release, that will be released in April and October.
