-Making Changes to the Yocto Project
-***********************************
-
-Because the Yocto Project is an open-source, community-based project,
-you can effect changes to the project. This section presents procedures
-that show you how to submit a defect against the project and how to
-submit a change.
-
-Submitting a Defect Against the Yocto Project
-=============================================
-
-Use the Yocto Project implementation of
-`Bugzilla <https://www.bugzilla.org/about/>`__ to submit a defect (bug)
-against the Yocto Project. For additional information on this
-implementation of Bugzilla see the ":ref:`Yocto Project
-Bugzilla <resources-bugtracker>`" section in the
-Yocto Project Reference Manual. For more detail on any of the following
-steps, see the Yocto Project
-:yocto_wiki:`Bugzilla wiki page </Bugzilla_Configuration_and_Bug_Tracking>`.
-
-Use the following general steps to submit a bug:
-
-#.  Open the Yocto Project implementation of :yocto_bugs:`Bugzilla <>`.
-
-#.  Click "File a Bug" to enter a new bug.
-
-#.  Choose the appropriate "Classification", "Product", and "Component"
-    for which the bug was found. Bugs for the Yocto Project fall into
-    one of several classifications, which in turn break down into
-    several products and components. For example, for a bug against the
-    ``meta-intel`` layer, you would choose "Build System, Metadata &
-    Runtime", "BSPs", and "bsps-meta-intel", respectively.
-
-#.  Choose the "Version" of the Yocto Project for which you found the
-    bug (e.g. &DISTRO;).
-
-#.  Determine and select the "Severity" of the bug. The severity
-    indicates how the bug impacted your work.
-
-#.  Choose the "Hardware" that the bug impacts.
-
-#.  Choose the "Architecture" that the bug impacts.
-
-#.  Choose a "Documentation change" item for the bug. Fixing a bug might
-    or might not affect the Yocto Project documentation. If you are
-    unsure of the impact to the documentation, select "Don't Know".
-
-#.  Provide a brief "Summary" of the bug. Try to limit your summary to
-    just a line or two and be sure to capture the essence of the bug.
-
-#.  Provide a detailed "Description" of the bug. You should provide as
-    much detail as you can about the context, behavior, output, and so
-    forth that surrounds the bug. You can even attach supporting files
-    for output from logs by using the "Add an attachment" button.
-
-#.  Click the "Submit Bug" button submit the bug. A new Bugzilla number
-    is assigned to the bug and the defect is logged in the bug tracking
-    system.
-
-Once you file a bug, the bug is processed by the Yocto Project Bug
-Triage Team and further details concerning the bug are assigned (e.g.
-priority and owner). You are the "Submitter" of the bug and any further
-categorization, progress, or comments on the bug result in Bugzilla
-sending you an automated email concerning the particular change or
-progress to the bug.
-
-Submitting a Change to the Yocto Project
-========================================
-
-Contributions to the Yocto Project and OpenEmbedded are very welcome.
-Because the system is extremely configurable and flexible, we recognize
-that developers will want to extend, configure or optimize it for their
-specific uses.
-
-The Yocto Project uses a mailing list and a patch-based workflow that is
-similar to the Linux kernel but contains important differences. In
-general, there is a mailing list through which you can submit patches. You
-should send patches to the appropriate mailing list so that they can be
-reviewed and merged by the appropriate maintainer. The specific mailing
-list you need to use depends on the location of the code you are
-changing. Each component (e.g. layer) should have a ``README`` file that
-indicates where to send the changes and which process to follow.
-
-You can send the patch to the mailing list using whichever approach you
-feel comfortable with to generate the patch. Once sent, the patch is
-usually reviewed by the community at large. If somebody has concerns
-with the patch, they will usually voice their concern over the mailing
-list. If a patch does not receive any negative reviews, the maintainer
-of the affected layer typically takes the patch, tests it, and then
-based on successful testing, merges the patch.
-
-The "poky" repository, which is the Yocto Project's reference build
-environment, is a hybrid repository that contains several individual
-pieces (e.g. BitBake, Metadata, documentation, and so forth) built using
-the combo-layer tool. The upstream location used for submitting changes
-varies by component:
-
--  *Core Metadata:* Send your patch to the
-   :oe_lists:`openembedded-core </g/openembedded-core>`
-   mailing list. For example, a change to anything under the ``meta`` or
-   ``scripts`` directories should be sent to this mailing list.
-
--  *BitBake:* For changes to BitBake (i.e. anything under the
-   ``bitbake`` directory), send your patch to the
-   :oe_lists:`bitbake-devel </g/bitbake-devel>`
-   mailing list.
-
--  *"meta-\*" trees:* These trees contain Metadata. Use the
-   :yocto_lists:`poky </g/poky>` mailing list.
-
--  *Documentation*: For changes to the Yocto Project documentation, use the
-   :yocto_lists:`docs </g/docs>` mailing list.
-
-For changes to other layers hosted in the Yocto Project source
-repositories (i.e. ``yoctoproject.org``) and tools use the
-:yocto_lists:`Yocto Project </g/yocto/>` general mailing list.
-
-.. note::
-
-   Sometimes a layer's documentation specifies to use a particular
-   mailing list. If so, use that list.
-
-For additional recipes that do not fit into the core Metadata, you
-should determine which layer the recipe should go into and submit the
-change in the manner recommended by the documentation (e.g. the
-``README`` file) supplied with the layer. If in doubt, please ask on the
-Yocto general mailing list or on the openembedded-devel mailing list.
-
-You can also push a change upstream and request a maintainer to pull the
-change into the component's upstream repository. You do this by pushing
-to a contribution repository that is upstream. See the
-":ref:`overview-manual/development-environment:git workflows and the yocto project`"
-section in the Yocto Project Overview and Concepts Manual for additional
-concepts on working in the Yocto Project development environment.
-
-Maintainers commonly use ``-next`` branches to test submissions prior to
-merging patches. Thus, you can get an idea of the status of a patch based on
-whether the patch has been merged into one of these branches. The commonly
-used testing branches for OpenEmbedded-Core are as follows:
-
--  *openembedded-core "master-next" branch:* This branch is part of the
-   :oe_git:`openembedded-core </openembedded-core/>` repository and contains
-   proposed changes to the core metadata.
-
--  *poky "master-next" branch:* This branch is part of the
-   :yocto_git:`poky </poky/>` repository and combines proposed
-   changes to BitBake, the core metadata and the poky distro.
-
-Similarly, stable branches maintained by the project may have corresponding
-``-next`` branches which collect proposed changes. For example,
-``&DISTRO_NAME_NO_CAP;-next`` and ``&DISTRO_NAME_NO_CAP_MINUS_ONE;-next``
-branches in both the "openembdedded-core" and "poky" repositories.
-
-Other layers may have similar testing branches but there is no formal
-requirement or standard for these so please check the documentation for the
-layers you are contributing to.
-
-The following sections provide procedures for submitting a change.
-
-Preparing Changes for Submission
---------------------------------
-
-#. *Make Your Changes Locally:* Make your changes in your local Git
-   repository. You should make small, controlled, isolated changes.
-   Keeping changes small and isolated aids review, makes
-   merging/rebasing easier and keeps the change history clean should
-   anyone need to refer to it in future.
-
-#. *Stage Your Changes:* Stage your changes by using the ``git add``
-   command on each file you changed.
-
-#. *Commit Your Changes:* Commit the change by using the ``git commit``
-   command. Make sure your commit information follows standards by
-   following these accepted conventions:
-
-   -  Be sure to include a "Signed-off-by:" line in the same style as
-      required by the Linux kernel. This can be done by using the
-      ``git commit -s`` command. Adding this line signifies that you,
-      the submitter, have agreed to the Developer's Certificate of
-      Origin 1.1 as follows:
-
-      .. code-block:: none
-
-         Developer's Certificate of Origin 1.1
-
-         By making a contribution to this project, I certify that:
-
-         (a) The contribution was created in whole or in part by me and I
-             have the right to submit it under the open source license
-             indicated in the file; or
-
-         (b) The contribution is based upon previous work that, to the best
-             of my knowledge, is covered under an appropriate open source
-             license and I have the right under that license to submit that
-             work with modifications, whether created in whole or in part
-             by me, under the same open source license (unless I am
-             permitted to submit under a different license), as indicated
-             in the file; or
-
-         (c) The contribution was provided directly to me by some other
-             person who certified (a), (b) or (c) and I have not modified
-             it.
-
-         (d) I understand and agree that this project and the contribution
-             are public and that a record of the contribution (including all
-             personal information I submit with it, including my sign-off) is
-             maintained indefinitely and may be redistributed consistent with
-             this project or the open source license(s) involved.
-
-   -  Provide a single-line summary of the change and, if more
-      explanation is needed, provide more detail in the body of the
-      commit. This summary is typically viewable in the "shortlist" of
-      changes. Thus, providing something short and descriptive that
-      gives the reader a summary of the change is useful when viewing a
-      list of many commits. You should prefix this short description
-      with the recipe name (if changing a recipe), or else with the
-      short form path to the file being changed.
-
-   -  For the body of the commit message, provide detailed information
-      that describes what you changed, why you made the change, and the
-      approach you used. It might also be helpful if you mention how you
-      tested the change. Provide as much detail as you can in the body
-      of the commit message.
-
-      .. note::
-
-         You do not need to provide a more detailed explanation of a
-         change if the change is minor to the point of the single line
-         summary providing all the information.
-
-   -  If the change addresses a specific bug or issue that is associated
-      with a bug-tracking ID, include a reference to that ID in your
-      detailed description. For example, the Yocto Project uses a
-      specific convention for bug references --- any commit that addresses
-      a specific bug should use the following form for the detailed
-      description. Be sure to use the actual bug-tracking ID from
-      Bugzilla for bug-id::
-
-         Fixes [YOCTO #bug-id]
-
-         detailed description of change
-
-Using Email to Submit a Patch
------------------------------
-
-Depending on the components changed, you need to submit the email to a
-specific mailing list. For some guidance on which mailing list to use,
-see the
-:ref:`list <dev-manual/changes:submitting a change to the yocto project>`
-at the beginning of this section. For a description of all the available
-mailing lists, see the ":ref:`Mailing Lists <resources-mailinglist>`" section in the
-Yocto Project Reference Manual.
-
-Here is the general procedure on how to submit a patch through email
-without using the scripts once the steps in
-:ref:`dev-manual/changes:preparing changes for submission` have been followed:
-
-#. *Format the Commit:* Format the commit into an email message. To
-   format commits, use the ``git format-patch`` command. When you
-   provide the command, you must include a revision list or a number of
-   patches as part of the command. For example, either of these two
-   commands takes your most recent single commit and formats it as an
-   email message in the current directory::
-
-      $ git format-patch -1
-
-   or ::
-
-      $ git format-patch HEAD~
-
-   After the command is run, the current directory contains a numbered
-   ``.patch`` file for the commit.
-
-   If you provide several commits as part of the command, the
-   ``git format-patch`` command produces a series of numbered files in
-   the current directory – one for each commit. If you have more than
-   one patch, you should also use the ``--cover`` option with the
-   command, which generates a cover letter as the first "patch" in the
-   series. You can then edit the cover letter to provide a description
-   for the series of patches. For information on the
-   ``git format-patch`` command, see ``GIT_FORMAT_PATCH(1)`` displayed
-   using the ``man git-format-patch`` command.
-
-   .. note::
-
-      If you are or will be a frequent contributor to the Yocto Project
-      or to OpenEmbedded, you might consider requesting a contrib area
-      and the necessary associated rights.
-
-#. *Send the patches via email:* Send the patches to the recipients and
-   relevant mailing lists by using the ``git send-email`` command.
-
-   .. note::
-
-      In order to use ``git send-email``, you must have the proper Git packages
-      installed on your host.
-      For Ubuntu, Debian, and Fedora the package is ``git-email``.
-
-   The ``git send-email`` command sends email by using a local or remote
-   Mail Transport Agent (MTA) such as ``msmtp``, ``sendmail``, or
-   through a direct ``smtp`` configuration in your Git ``~/.gitconfig``
-   file. If you are submitting patches through email only, it is very
-   important that you submit them without any whitespace or HTML
-   formatting that either you or your mailer introduces. The maintainer
-   that receives your patches needs to be able to save and apply them
-   directly from your emails. A good way to verify that what you are
-   sending will be applicable by the maintainer is to do a dry run and
-   send them to yourself and then save and apply them as the maintainer
-   would.
-
-   The ``git send-email`` command is the preferred method for sending
-   your patches using email since there is no risk of compromising
-   whitespace in the body of the message, which can occur when you use
-   your own mail client. The command also has several options that let
-   you specify recipients and perform further editing of the email
-   message. For information on how to use the ``git send-email``
-   command, see ``GIT-SEND-EMAIL(1)`` displayed using the
-   ``man git-send-email`` command.
-
-The Yocto Project uses a `Patchwork instance <https://patchwork.yoctoproject.org/>`__
-to track the status of patches submitted to the various mailing lists and to
-support automated patch testing. Each submitted patch is checked for common
-mistakes and deviations from the expected patch format and submitters are
-notified by patchtest if such mistakes are found. This process helps to
-reduce the burden of patch review on maintainers.
-
-.. note::
-
-   This system is imperfect and changes can sometimes get lost in the flow.
-   Asking about the status of a patch or change is reasonable if the change
-   has been idle for a while with no feedback.
-
-Using Scripts to Push a Change Upstream and Request a Pull
-----------------------------------------------------------
-
-For larger patch series it is preferable to send a pull request which not
-only includes the patch but also a pointer to a branch that can be pulled
-from. This involves making a local branch for your changes, pushing this
-branch to an accessible repository and then using the ``create-pull-request``
-and ``send-pull-request`` scripts from openembedded-core to create and send a
-patch series with a link to the branch for review.
-
-Follow this procedure to push a change to an upstream "contrib" Git
-repository once the steps in :ref:`dev-manual/changes:preparing changes for submission` have
-been followed:
-
-.. note::
-
-   You can find general Git information on how to push a change upstream
-   in the
-   `Git Community Book <https://git-scm.com/book/en/v2/Distributed-Git-Distributed-Workflows>`__.
-
-#. *Push Your Commits to a "Contrib" Upstream:* If you have arranged for
-   permissions to push to an upstream contrib repository, push the
-   change to that repository::
-
-      $ git push upstream_remote_repo local_branch_name
-
-   For example, suppose you have permissions to push
-   into the upstream ``meta-intel-contrib`` repository and you are
-   working in a local branch named `your_name`\ ``/README``. The following
-   command pushes your local commits to the ``meta-intel-contrib``
-   upstream repository and puts the commit in a branch named
-   `your_name`\ ``/README``::
-
-      $ git push meta-intel-contrib your_name/README
-
-#. *Determine Who to Notify:* Determine the maintainer or the mailing
-   list that you need to notify for the change.
-
-   Before submitting any change, you need to be sure who the maintainer
-   is or what mailing list that you need to notify. Use either these
-   methods to find out:
-
-   -  *Maintenance File:* Examine the ``maintainers.inc`` file, which is
-      located in the :term:`Source Directory` at
-      ``meta/conf/distro/include``, to see who is responsible for code.
-
-   -  *Search by File:* Using :ref:`overview-manual/development-environment:git`, you can
-      enter the following command to bring up a short list of all
-      commits against a specific file::
-
-         git shortlog -- filename
-
-      Just provide the name of the file for which you are interested. The
-      information returned is not ordered by history but does include a
-      list of everyone who has committed grouped by name. From the list,
-      you can see who is responsible for the bulk of the changes against
-      the file.
-
-   -  *Examine the List of Mailing Lists:* For a list of the Yocto
-      Project and related mailing lists, see the ":ref:`Mailing
-      lists <resources-mailinglist>`" section in
-      the Yocto Project Reference Manual.
-
-#. *Make a Pull Request:* Notify the maintainer or the mailing list that
-   you have pushed a change by making a pull request.
-
-   The Yocto Project provides two scripts that conveniently let you
-   generate and send pull requests to the Yocto Project. These scripts
-   are ``create-pull-request`` and ``send-pull-request``. You can find
-   these scripts in the ``scripts`` directory within the
-   :term:`Source Directory` (e.g.
-   ``poky/scripts``).
-
-   Using these scripts correctly formats the requests without
-   introducing any whitespace or HTML formatting. The maintainer that
-   receives your patches either directly or through the mailing list
-   needs to be able to save and apply them directly from your emails.
-   Using these scripts is the preferred method for sending patches.
-
-   First, create the pull request. For example, the following command
-   runs the script, specifies the upstream repository in the contrib
-   directory into which you pushed the change, and provides a subject
-   line in the created patch files::
-
-      $ poky/scripts/create-pull-request -u meta-intel-contrib -s "Updated Manual Section Reference in README"
-
-   Running this script forms ``*.patch`` files in a folder named
-   ``pull-``\ `PID` in the current directory. One of the patch files is a
-   cover letter.
-
-   Before running the ``send-pull-request`` script, you must edit the
-   cover letter patch to insert information about your change. After
-   editing the cover letter, send the pull request. For example, the
-   following command runs the script and specifies the patch directory
-   and email address. In this example, the email address is a mailing
-   list::
-
-      $ poky/scripts/send-pull-request -p ~/meta-intel/pull-10565 -t meta-intel@lists.yoctoproject.org
-
-   You need to follow the prompts as the script is interactive.
-
-   .. note::
-
-      For help on using these scripts, simply provide the ``-h``
-      argument as follows::
-
-              $ poky/scripts/create-pull-request -h
-              $ poky/scripts/send-pull-request -h
-
-Responding to Patch Review
---------------------------
-
-You may get feedback on your submitted patches from other community members
-or from the automated patchtest service. If issues are identified in your
-patch then it is usually necessary to address these before the patch will be
-accepted into the project. In this case you should amend the patch according
-to the feedback and submit an updated version to the relevant mailing list,
-copying in the reviewers who provided feedback to the previous version of the
-patch.
-
-The patch should be amended using ``git commit --amend`` or perhaps ``git
-rebase`` for more expert git users. You should also modify the ``[PATCH]``
-tag in the email subject line when sending the revised patch to mark the new
-iteration as ``[PATCH v2]``, ``[PATCH v3]``, etc as appropriate. This can be
-done by passing the ``-v`` argument to ``git format-patch`` with a version
-number.
-
-Lastly please ensure that you also test your revised changes. In particular
-please don't just edit the patch file written out by ``git format-patch`` and
-resend it.
-
-Submitting Changes to Stable Release Branches
----------------------------------------------
-
-The process for proposing changes to a Yocto Project stable branch differs
-from the steps described above. Changes to a stable branch must address
-identified bugs or CVEs and should be made carefully in order to avoid the
-risk of introducing new bugs or breaking backwards compatibility. Typically
-bug fixes must already be accepted into the master branch before they can be
-backported to a stable branch unless the bug in question does not affect the
-master branch or the fix on the master branch is unsuitable for backporting.
-
-The list of stable branches along with the status and maintainer for each
-branch can be obtained from the
-:yocto_wiki:`Releases wiki page </Releases>`.
-
-.. note::
-
-   Changes will not typically be accepted for branches which are marked as
-   End-Of-Life (EOL).
-
-With this in mind, the steps to submit a change for a stable branch are as
-follows:
-
-#. *Identify the bug or CVE to be fixed:* This information should be
-   collected so that it can be included in your submission.
-
-   See :ref:`dev-manual/vulnerabilities:checking for vulnerabilities`
-   for details about CVE tracking.
-
-#. *Check if the fix is already present in the master branch:* This will
-   result in the most straightforward path into the stable branch for the
-   fix.
-
-   #. *If the fix is present in the master branch --- submit a backport request
-      by email:* You should send an email to the relevant stable branch
-      maintainer and the mailing list with details of the bug or CVE to be
-      fixed, the commit hash on the master branch that fixes the issue and
-      the stable branches which you would like this fix to be backported to.
-
-   #. *If the fix is not present in the master branch --- submit the fix to the
-      master branch first:* This will ensure that the fix passes through the
-      project's usual patch review and test processes before being accepted.
-      It will also ensure that bugs are not left unresolved in the master
-      branch itself. Once the fix is accepted in the master branch a backport
-      request can be submitted as above.
-
-   #. *If the fix is unsuitable for the master branch --- submit a patch
-      directly for the stable branch:* This method should be considered as a
-      last resort. It is typically necessary when the master branch is using
-      a newer version of the software which includes an upstream fix for the
-      issue or when the issue has been fixed on the master branch in a way
-      that introduces backwards incompatible changes. In this case follow the
-      steps in :ref:`dev-manual/changes:preparing changes for submission` and
-      :ref:`dev-manual/changes:using email to submit a patch` but modify the subject header of your patch
-      email to include the name of the stable branch which you are
-      targetting. This can be done using the ``--subject-prefix`` argument to
-      ``git format-patch``, for example to submit a patch to the dunfell
-      branch use
-      ``git format-patch --subject-prefix='&DISTRO_NAME_NO_CAP_MINUS_ONE;][PATCH' ...``.
