Launchpad bugs are used to track known issues and defects in OpenStack software.

Bugs reference

Here are the different fields available in Launchpad bugs, and how we use them within the OpenStack project.


In Progress
Fix Committed
Fix Released
Won't Fix


This should be set when the status reaches Confirmed stage. It is a combination of short-term impact (unavailability of a feature), long-term impact (data corruption, security breach), number of people affected, and presence of a documented workaround. Use these as guidelines:


Note that presence of Critical bugs will delay the release.

Assigned To

The person currently working to fix this bug. Must be set by In progress stage.


The milestone we need to fix the bug for, or the milestone/version it was fixed in.


Free-form tags you can use to search bugs with. Here is the list of official tags.

Bugs lifecycle

Bugs go through multiple stages before final resolution.


When you find a bug, you should file it against the proper OpenStack project using the corresponding link:

Make sure there is no bug already filed for the same issue, then enter the details of your report. It should at least include:

  • The release, or miletone, or commitid) corresponding to the software that you are running

When this is done, the bug is created with:

  • Status: New

Confirming & prioritizing

This stage is about checking that a bug is real and assessing its impact. If you are lacking information to properly reproduce or assess the importance of the bug, you should ask the original reporter for more information and set the bug to:

  • Status: Incomplete

Once you have reproduced the issue (or are 100% confident that this is indeed a valid bug), you should set:

  • Status: Confirmed

If you're a core developer or a member of the project bug supervision team, you should also prioritize the bug:

  • Importance: <Bug impact> (see above)

Debugging (optional)

This optional stage is about determining how to fix the bug and posting the solution in the comments. Sometimes the implementation of the fix will be straightforward and you would jump directly to bugfixing, but in some other cases, you would just post your complete debugging analysis and give someone else the opportunity of fixing the bug. Then you should ask a core developer or bug supervisor to set:

  • Status: Triaged


At this stage, a developer will work on a fix. During that time, in order to avoid duplicating the work, he should set:

  • Status: In progress
  • Assignee: <yourself>

When the fix is ready, he will propose the change and get it reviewed.

Note that Gerrit will automatically set the status and assignee when a change is proposed that mentions the bug number.

After the change is accepted

Once the change is reviewed, accepted, and has landed in master, it will automatically move to:

  • Status: Fix Committed

When the fix makes it into a milestone or release branch, it will automatically move to:

  • Milestone: Milestone the bug was fixed in
  • Status: Fix Released
