== Bug Tracking ==
== Bug Tracking ==
Yocto spans many geographies.  A single bug scrub meeting is not easy to maintain. Because Embedded Linux is a large, active project, a ''Triage'' is used to effectively track bugs. Triage is mainly for setting new bug priorities. The Bug Triage team determines a bug's severity, features, and schedule to best facilitate a bug's resolution.  Developer teams receive Triage email in time. If the team reaches agreement, bugs are followed up based on their priority. The Bug Triage Manager is responsible for monitoring the bug fixing schedule such that it aligns with the related priority. The triage process ensures the high priority bugs are fixed in time and reduces the schedule risk. Separate bug review and discussion still exist and are held through Jabber.  
Because the Yocto Project spans many geographies and is a large and active project, a single bug scrub meeting is not easy to maintain. Consequently, a ''Triage'' is used to effectively disposition bugs. The Bug Triage team reviews a bug's severity and features and then schedules the bug to best facilitate a resolution.  The Triage team sets new bug priorities, corrects ownership for the work to be done, and ensures an appropriate target milestone for the bug. The Triage process is documented at [[Bug_Triage]].
 
=== Triage Management Team ===
* Triage Chairman (rotating assignment)
* Program Manager
* Architect
* Engineering Manager
* QA leader
 
=== Triage Process ===
The triage process is held frequently to make sure new bugs are set with correct priority in time. The Triage Chairman scrubs new bugs and set priority everyday. PDT meeting will review past week's overall triage result once per week.
 
The Bugzilla system sends emails to component owners and related engineers when bugs are created or change.  Before Triage, new bugs could be discussed and even fixed.

<pre>
To: Yocto OTC
Subject: [Yocto-bug-triage] Bug Triage Review - ww26.1


Manager: MGR_A
Part of the Triage process is the distribution of a weekly Bugzilla Cleanup Request.  This email request is a reminder for bug owners when various parameters of a bug are not in line with the Yocto Project Bugzilla tracking system.  For example, if a bug has no estimate information or milestone by which it should complete.  Following is a summary of the type of information in the weekly Bugzilla Cleanup Request.  For the actual request, links to lists of bugs exist that allow you to see the list of bugs that fail to meet a particular requirement:
==================
Bug ID    Sev  Priority  Assignee  Summary
1        maj  High      dev_A      [Poky] XYZ Build Failure


Manager: MGR_B
*'''No Estimate:''' You own a medium or higher priority bug or enhancement in Bugzilla targeted for completion in the given release.  Do to the amount of work trying to get done in Yocto Project, we are asking you take a minute or two and give an estimated amount of work – in "Perfect-Work-Days" – to complete the bug or enhancement.  We know your estimates might not be perfect.  However, this effort helps us know who is overloaded with work and where to apply the resources we have on the project.  Please estimate how many "Perfect-Work-Days" remain to close the bugs in the "Estimate: Person-Days" box in Bugzilla.  Also while updating the bug or enhancement, please ensure the estimate targets the correct Milestone for completion.
====================
Bug ID    Sev  Priority  Assignee  Summary
2        maj  High      dev_B      [SDK] ABC button error
3        nor  Medium    dev_C      [X] Can't start X
</pre>


=== Responsibility ===
*'''Old Milestone:''' You are assigned an open bug in the Yocto Project Bugzilla tracker whose assigned milestone is old.  To see the list of bugs with old milestones please look here:  https://wiki.yoctoproject.org/wiki/Bug_Triage#Old_Milestone.  Since the milestone for this bug in the Yocto Project has already passed, please do one of the following actions:
* Triage Chairman
**If it is completed: Close the bug. (Great News!)
** Triage new bugs: set initial priority, correct bug component and owner and mark duplicated bugs.  
**If it is partly complete: Break the bug request into two or more parts and close what is done and move the remaining parts to a future milestone.
** Monitor overall bug fix progress with indicators: find out aging bugs.
**If it is not done at all but you still plan to fix it in the future: Move the bug to milestone that is not yet completed.  (Future is a possible milestone.) 
** Send out triage result email to Yocto mailing list (or Triage management team member) for review. 
**If it is no longer in your plans to do this but you think this still needs to be fixed: Change the bug to an unassigned priority.  During the Triage process, we will assess the bug again and appropriately reassign the bug.
** Escalate aging high priority open bugs.
**If it no longer makes sense to fix this bug: Please close the bug request with a status of either OBSOLETE or WONTFIX.
* Triage Management Team
** Development/Distribution managers are mandatory to review triage result and commit to fix
* Development/Distribution Manager
** Ensure developer/distro '''ACCEPT''' bugs in Bugzilla within three days
** Commit developer to fix high priority bugs
* Program Manager
** Coordinate and push bugs to be fixed in time
* Triage Decision Forum (PDT Meeting)
** Make decision on controversial bugs
** Review and Monitor previous decision
** Triage Chairman update Bugzilla based on decision
** Discuss and approve bug whose priority needs to be downgraded


=== Triage Chairman ===
*'''Needs specific milestone:''' You are assigned an open bug or enhancement in the Yocto Project Bugzilla tracker that has a medium+ or high priority assigned to it without a targeted specific milestone or specific dot release.   All open medium+ or high bugs must have a specific target milestone or specific dot release assigned to them (e.g. 2.2.3). Medium+ and High bugs are not allowed to be set to the "Future" milestone but can be set to the milestone 2.99 which time to complete is still TBD.
Triage chairman role will be rotated in distribution leaders, engineer manager, SDK leader and QA leader. Each chairman will own one milestone cycle. Triage chairman starts from Yocto 0.9 M2 cycle and rotate in following order.  
# Saul Wold -- Distro leader
# Susie Li -- engineer manager
# Kevin Tian -- distro leader
# Jessica Zhang -- SDK leader
# QA Leader


=== Bug Data Reporting ===
*'''Needs to be broken up:''' You are assigned an open bug or enhancement in the Yocto Project Bugzilla tracker that is a medium or higher priority and has more than five "Perfect-Work-Days" assigned.   All open medium or higher bugs with more than five days should be broken into smaller dependent tasks.  If this is not possible please contact the Yocto Project program manager with bug number and an explanation of why it can't be broken into small tasks.  
Defect Data is tracked and presented to the PDT meeting on a weekly basis by QA team. Any escalation items should be discussed and resolved in the PDT meeting.


=== External Owned Bug Triage ===
*'''Dependency Issue:''' You have a dependency problem in Yocto Project Bugzilla tracker where either your bug or enhancement is dependent on a lower priority bug or enhancement, or your bug or enhancement has a target milestone earlier than dependent bugs or enhancements. Please open your bug and review the dependencies to see what the problem is with the bug.
There might be some bugs owned by external developers. These bugs' triage results are sent to the Yocto public mailing list weekly.  


=== Re-Triage for Next Milestone and Release ===
*'''Need Info > 2 Weeks:''' You have bugs or requested enhancements for the Yocto Project for which more information has been requested in order to allow progress on these bugs.  These bugs or enhancements have been in this state waiting for this information from you for at least two weeks.  Please update the bug or enhancement request at: https://wiki.yoctoproject.org/wiki/Bug_Triage#NEEDINFO to have the requested information so that work on this bug or enhancement can move forward. If you cannot supply the information, please change the bug's status to CLOSED and the resolution to either OBSOLETE or WONTFIX, whichever is more appropriate.
After a new milestone, there will be a time to review all medium priority bugs and set new Priority for next coming milestone.
After a new release, there will be a time to review all low priority bugs and set new Priority for next coming release.


== Feature Request Process ==
== Feature Request Process ==
New feature request should be applied through Bugzilla as a bug. User could select corresponding Severity to indicate how important the feature is. User needs to follow Feature Request template to submit new request. Triage chairman will mark new feature request bug priority to '''FEAT'''.
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 Aug. and Jan. (2 months before current release). In the review period, there will be 2~4 times review meetings by CCB. CCB will decide new features which will be included in next release, that will be released 8 months later. If feature request missed the review period, in theory it will be missed in next release. Any approved new feature will be reset Priority value and Target Version value. Non approved feature will keep "FEAT" priority.
 
=== Change Control Board ===
Following people should join CCB to review new feature request.
PME(Product Marketing Engineer), PM, Architect, Managers, Key developer and QA leader
 
=== Feature Request Bug Requirement ===
Feature request bug should be added specific Keywords in subject and Keywords field.
 
Following message should be added at the beginning of subject.
[FEAT_REQ Company Yocto_Target_Version]
 
For example: [FEAT_REQ xxx 1.0] Add Connman for network connection.
 
Following words should be added in Keywords field.
FEATURE_REQUEST
 
=== Feature Request Bug Template ===
<pre>
1. Feature Description:
 
2. Feature Present Code Status(including location and version):
 
3. Code License (e.g. GPLv2):
 
4. Business Impaction:
 
5. Other Justification:
 
</pre>
 
=== Bug Tracking template ===
 
<p>- Headline (tittle).</p>
<p>- Steps to reproduce it, (Expected and actual results).</p>
<p>- Reproducibility.</p>
<p>- Attachments (pics, logs).</p>
<p>- Build Description ( poky commit, machine, HW, test environment).</p>
<p>- AB Link.</p>
<p>- Summary (on Description).</p>
<p>- Additional Versions or HW.</p>
<p>- Link to corresponding test case.</p>
 
=== Best Practices redacting headline ===
1. No more than 12 words.
<p>2. In 12 words include:</p>
  a) Who.
  b) What.
  c) When.
Examples:
 
<p>1. SATO-sdk displays panics kernel when trying to Install from USB.</p>
<p>SATO-sdk = Who.</p>
<p>Displays panics kernel = What.</p>
<p>Trying to Install from USB = When.</p>


<p>2. Git revision field editing fail on importing layers.</p>
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.
<p>Git revision field = Who.</p>
<p>Editing fail = What.</p>
<p>On imporing layers = When.</p>
<p>Note: You can describe "How" to reproduce it in the description.</p>

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:

  • 2.0.3
  • 2.0.4

  • 2.2.3
  • 2.3
  • 2.3.1
  • 2.3.2
  • 2.4
  • 2.5
  • Unspecified

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.
  • 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

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

Part of the Triage process is the distribution of a weekly Bugzilla Cleanup Request. This email request is a reminder for bug owners when various parameters of a bug are not in line with the Yocto Project Bugzilla tracking system. For example, if a bug has no estimate information or milestone by which it should complete. Following is a summary of the type of information in the weekly Bugzilla Cleanup Request. For the actual request, links to lists of bugs exist that allow you to see the list of bugs that fail to meet a particular requirement:

  • No Estimate: You own a medium or higher priority bug or enhancement in Bugzilla targeted for completion in the given release. Do to the amount of work trying to get done in Yocto Project, we are asking you take a minute or two and give an estimated amount of work – in "Perfect-Work-Days" – to complete the bug or enhancement. We know your estimates might not be perfect. However, this effort helps us know who is overloaded with work and where to apply the resources we have on the project. Please estimate how many "Perfect-Work-Days" remain to close the bugs in the "Estimate: Person-Days" box in Bugzilla. Also while updating the bug or enhancement, please ensure the estimate targets the correct Milestone for completion.
  • Old Milestone: You are assigned an open bug in the Yocto Project Bugzilla tracker whose assigned milestone is old. To see the list of bugs with old milestones please look here: https://wiki.yoctoproject.org/wiki/Bug_Triage#Old_Milestone. Since the milestone for this bug in the Yocto Project has already passed, please do one of the following actions:
    • If it is completed: Close the bug. (Great News!)
    • If it is partly complete: Break the bug request into two or more parts and close what is done and move the remaining parts to a future milestone.
    • If it is not done at all but you still plan to fix it in the future: Move the bug to milestone that is not yet completed. (Future is a possible milestone.)
    • If it is no longer in your plans to do this but you think this still needs to be fixed: Change the bug to an unassigned priority. During the Triage process, we will assess the bug again and appropriately reassign the bug.
    • If it no longer makes sense to fix this bug: Please close the bug request with a status of either OBSOLETE or WONTFIX.
  • Needs specific milestone: You are assigned an open bug or enhancement in the Yocto Project Bugzilla tracker that has a medium+ or high priority assigned to it without a targeted specific milestone or specific dot release. All open medium+ or high bugs must have a specific target milestone or specific dot release assigned to them (e.g. 2.2.3). Medium+ and High bugs are not allowed to be set to the "Future" milestone but can be set to the milestone 2.99 which time to complete is still TBD.
  • Needs to be broken up: You are assigned an open bug or enhancement in the Yocto Project Bugzilla tracker that is a medium or higher priority and has more than five "Perfect-Work-Days" assigned. All open medium or higher bugs with more than five days should be broken into smaller dependent tasks. If this is not possible please contact the Yocto Project program manager with bug number and an explanation of why it can't be broken into small tasks.
  • Dependency Issue: You have a dependency problem in Yocto Project Bugzilla tracker where either your bug or enhancement is dependent on a lower priority bug or enhancement, or your bug or enhancement has a target milestone earlier than dependent bugs or enhancements. Please open your bug and review the dependencies to see what the problem is with the bug.
  • Need Info > 2 Weeks: You have bugs or requested enhancements for the Yocto Project for which more information has been requested in order to allow progress on these bugs. These bugs or enhancements have been in this state waiting for this information from you for at least two weeks. Please update the bug or enhancement request at: https://wiki.yoctoproject.org/wiki/Bug_Triage#NEEDINFO to have the requested information so that work on this bug or enhancement can move forward. If you cannot supply the information, please change the bug's status to CLOSED and the resolution to either OBSOLETE or WONTFIX, whichever is more appropriate.

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.
