3 The Role of Maintainers
4 =======================
6 Maintainers are a critical part of the project's contributor ecosystem.
7 They come from a wide range of backgrounds from unpaid hobbyists
8 working in their spare time to employees who work on the project as
9 part of their job. Maintainer activities include:
11 - reviewing patches and suggesting changes
12 - collecting patches and preparing pull requests
13 - tending to the long term health of their area
14 - participating in other project activities
16 They are also human and subject to the same pressures as everyone else
17 including overload and burnout. Like everyone else they are subject
18 to project's :ref:`code_of_conduct` and should also be exemplars of
19 excellent community collaborators.

26 file contains the canonical list of who is a maintainer. The file
27 is machine readable so an appropriately configured git (see
28 :ref:`cc_the_relevant_maintainer`) can automatically Cc them on
29 patches that touch their area of code.
31 The file also describes the status of the area of code to give an idea
32 of how actively that section is maintained.
34 .. list-table:: Meaning of support status in MAINTAINERS
41 - Someone is actually paid to look after this.
43 - Someone actually looks after it.
45 - It has a maintainer but they don't have time to do
46 much other than throw the odd patch in.
48 - No current maintainer.
50 - Old obsolete code, should use something else.
52 Please bear in mind that even if someone is paid to support something
53 it does not mean they are paid to support you. This is open source and
54 the code comes with no warranty and the project makes no guarantees
55 about dealing with bugs or features requests.
62 Most maintainers start by becoming subsystem reviewers. While anyone
63 is welcome to review code on the mailing list getting added to the
64 MAINTAINERS file with a line like::
66 R: Random Hacker <rhacker@example.com>
68 marks you as a 'designated reviewer' - expected to provide regular
69 spontaneous feedback. This will ensure that patches touching a given
70 subsystem will automatically be CC'd to you.
75 Maintainers are volunteers who put themselves forward or have been
76 asked by others to keep an eye on an area of code. They have generally
77 demonstrated to the community, usually via contributions and code
78 reviews, that they have a good understanding of the subsystem. They
79 are also trusted to make a positive contribution to the project and
80 work well with the other contributors.
82 The process is simple - simply send a patch to the list that updates
83 the ``MAINTAINERS`` file. Sometimes this is done as part of a larger
84 series when a new sub-system is being added to the code base. This can
85 also be done by a retiring maintainer who nominates their replacement
86 after discussion with other contributors.
88 Once the patch is reviewed and merged the only other step is to make
89 sure your GPG key is signed.
96 GPG is used to sign pull requests so they can be identified as really
97 coming from the maintainer. If your key is not already signed by
98 members of the QEMU community, you should make arrangements to attend
99 a `KeySigningParty <https://wiki.qemu.org/KeySigningParty>`__ (for
100 example at KVM Forum) or make alternative arrangements to have your
101 key signed by an attendee. Key signing requires meeting another
102 community member **in person** [#]_ so please make appropriate
105 .. [#] In recent pandemic times we have had to exercise some
106 flexibility here. Maintainers still need to sign their pull
