FreeBSD 8.0 release engineering TODO

/!\ This page is of historical interest only.

This is the FreeBSD 8.0 release engineering wiki page. It tracks the status of the FreeBSD 8.0 release process, including schedule, branching condition, change request queues, TODO lists, known issues, and more. It is updated daily during the release process.

Please only edit this page if you are a member of the release engineering team, or if a member of the release engineering team has asked you to do so.

Release Status

FreeBSD 8.0 is in the release candidate series. 8.0-RC1 has been released, and 8.0-RC2 builds are currently planned for approximately 14 October.

Currently, we are working to resolve problems with Position-Independent Executable (PIE) binaries introduced by the recent NULL-mapping vulnerability mitigation work. This prevents certain binaries, both (rare but important) native binaries and certain Linux binaries from running while mitigation is enabled. Bug fixes are now in progress for the kernel image activator and runtime linker to address these problems. Once they are resolved, RC2 builds will commence.

We continue to track problems reported with booting from USB media, associated with boot order and dependencies in the USB/CAM stack, which may also affect firewire. We hope that these will be resolved for 8.0.

We are currently collecting errata information for the release, in order to document issues that will not be solved for 8.0.

The head branch has now been named 9-CURRENT and has reopened for conservative commits as the 8.0 release process continues. Developers are asked to avoid sweeping changes that may make it difficult to merge fixes from 9-CURRENT to 8.0.

Change approval and merge guidelines

Change request guidelines

In order to submit a patch to the release engineering patch queue, you must be a FreeBSD developer able to commit the patch. If you are not a committer, you will need to identify a committer to proxy your request.

Please follow these guidelines when submitting patches -- all submissions must:

  1. include complete patches inline or attached to the e-mail; a URL is not sufficient. Use "svn diff -x -p" where appropriate. Diff at the src/ or src/sys. The diff shall be done against merged tree, and include the svn:mergeinfo changes.
  2. be fully build- and run-time tested.
  3. be reviewed before submission; include this review information with your submission.
  4. include a proposed commit message.
  5. unless exceptional circumstances apply, have baked in head for at least three days before a merge is requested.
  6. include the head revision number that will be merged.

Requests that do not follow these guidelines may be rejected without further consideration.

Change merge guidelines

The following guidelines must be followed when merging changes from head to stable/8:

  1. Unless approved by the release engineering team, changes must be committed to head before being merged to stable/8.
  2. When merging, use the instructions found in SubversionPrimer/Merging. Each changeset committed to head must be merged using svn merge as a single changeset to stable/8.
  3. Do not manually edit changes being merged to stable/8 without release engineering approval.
  4. Pay particular attention to the placement of mergeinfo.
  5. When committing the merge, include the original revision number (rXXXXXX) and a copy of the original commit message in the merge commit message.

Contact the release engineering team if you require assistance with the use of svn merge.

Release engineering issue and patch queue

The being-fixed and still-being-researched pile

Late-flying issues that have been resolved:

Blanket approvals

The following blanket approvals were valid until BETA3:

The following blanket approvals extend into the RC series:

The waiting for approval pile

This includes only changes requested as of 20090715.

The additional review or revisions sought pile

Sometimes the release engineering team will solicit further review or revisions for patches received; this list includes only changes requested as of 20090715.

The approved and queued for commit pile

These changes have been approved for commit to head and stable/8; this list includes only changes requested as of 20090715.

These changes have been approved for merge to stable/8 follow the release of the code freeze on head:

Committed fix pile

Changes that now appear in stable/8; this list includes only changes requested as of 20090715.

As of 20090812, fixes must be committed to head and then merged to stable/8. The following changes are now present in stable/8:

As of 20090823, changes may be committed to head without release engineering approval, but merges to stable/8 require approval:

The change request withdrawn pile

Changes in this list were requested, and then later withdrawn. This list includes only changes requested as of 20080715.

Rejected change request pile

This list contains changes requested during the end portion of the release cycle that were rejected, most likely due to the late point in the release cycle. This includes only changes requested as of 20080715.

Likely errata items

The following known issues are unlikely to be resolved before FreeBSD 8.0, and will require errata items:

Leading up to the release
