[PATCH v5 0/1] update MAINTAINERS file with git trailers

[PATCH v5 0/1] update MAINTAINERS file with git trailers

[Guinevere Larsen]

Some private chats highlighted that the currently in use git trailers
aren't explained well enough. This patch aims to fix that by adding the
information in a more verbose way to guarantee that everyone is on the
same page about them and refine anything that might still need work.

I forgot that Kevin had given a soft approval of this, so I kept his
review tag, but further chatter on the latest cauldron conference had
people agreeing that Acked-by should be used as partial approval, so I
reworded that section of the patch to be more inline with how other
projects use it.

One concern that was raised in the conference is how b4 reacts to
trailing parenthesis. It seems that newer b4 versions (at least on
0.12.3) drop that, while older versions (0.10.1) keep it. I'm not sure
if this change was intentional or not, and I have informed the b4
project of the regression, but this raises the question: Do we want to
have the trailing parenthesis saying which areas were approved by an
ack, or is it ok to just have it in regular text?

Personally I like adding it either way in replies, but not making it a
requirement when pushing code, so its easy to see in old emails and no
one gets inconvenienced, but I'm not dead set on this.

[PATCH v5 1/1] [gdb]: add git trailer information on gdb/MAINTAINERS

[Guinevere Larsen]

The project has been using Tested-By (tb), Reviewed-By (rb) and
Approved-By (ab) for some time, but there has been no information to be
found in the actual repository. This commit changes that by adding
information about all git trailers to the MAINTAINERS file, so that it
can be easily double-checked.

In the GDB BoF in 2023's GNU tools cauldron it was discussed and agreed
that Acked-by is already in use to represent partial approvals for
projects like the Linux Kernel and QEMU, so it makes sense to use it
similarly on this project.

Finally, for completeness sake, the trailers Co-Authored-By and Bug
were added, even though they have been in use for some time already

An extremely nitty nit: maybe I'm overthinking this, but in the examples
that use emails, the < > characters are meant to appear in the real
trailer, around the email address.  For the bug link, you used them as a
placeholder, and they are not meant to appear on the actual Bug: line.
Maybe something like this?

  Usage: "Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=..."

I don't know, either way your change looks good to me.  However, I was
not really part of those discussions, so I'd rather let someone else
approve the change, if possible.

What are the possible "area"s?  And how to indicate more than a single
area?

And a more general question: when the review comments are minor, we
are used to say something like "okay with those nits fixed", meaning
that there's no need for posting another version of the patch before
committing it "with those nits fixed".  Is this an
Acked-By/Approved-By or Reviewed-By?

Thanks.

"area of GDB" is used throughout the maintainers file without being 
specified anywhere, such as when explaining "Authorized Comitters":
   - The Authorized Committers.

     These are developers who are trusted to make changes within a specific
     area of GDB without additional oversight.

And all throughout the "Responsible maintainers" section. So I think it 
is understood well enough, especially since it is expected that the 
reviewers are the ones who should know if the patch touches multiple 
areas and so on.

As for how to indicate more than one area in the tag itself, I thought 
of a comma separated list. I'll update the example to say the following:

     Usage: "Acked-By: Your Name <your@email> (area1[, area2, ...])"

The tags are just ways to make your intent obvious. If you were 
approving the patch "with the nits fixed", you use Approved-By, if you 
were approving only parts of the patch, use Acked-by, and if you think 
the patch is ok but can't/won't approve, use Reviewed-By.

Fine by me, but then I think the text describing the tags should say
explicitly that the areas are those mentioned elsewhere in the
document.

I think this should also be in the document explicitly.

To indicate partial approval or partial review or even partial testing,
I recommend that we simply add "(area)" after the tag.

E.g.  if a reviewer has partially reviewed a patch and finds the parts
that change the gdbserver portions of it to be acceptable, they might
say:

Reviewed-by: Random J Developer <random@developer.example.org> (gdbserver)

The same could be done with the "Approved-by" tag.  If this is done,
then multiple partial approvals may be needed.

I think that an "Acked-by" tag could be useful when someone else has
done a detailed analysis and an area or global maintainer wishes to
indicate that they've read or skimmed the review, but have not done
any detailed analysis themselves.  It might also be used to indicate
agreement with direction of the patch after reading the commit log. 
But I don't think that it should be considered as strong as
"Reviewed-by" and definitely not as strong as "Approved-by".

I reached those conclusions after looking at how two other projects,
the git and kernel projects, use "Acked-by" and "Reviewed-by".  The
links that I looked at are:

https://git-scm.com/docs/SubmittingPatches
https://docs.kernel.org/process/submitting-patches.html

The git project has this to say about "Acked-by":

    Acked-by: says that the person who is more familiar with the area
    the patch attempts to modify liked the patch.

For the git project, "Reviewed-by" is much stronger:

    Reviewed-by: unlike the other tags, can only be offered by the
    reviewers themselves when they are completely satisfied with the
    patch after a detailed analysis.

Here's how the kernel project uses Acked-by:

    Aked-by:  is often used by the maintainer of the affected code
    when that maintainer neither contributed to nor forwarded the
    patch.

    Acked-by:  is not as formal as Signed-off-by:.  It is a record
    that the acker has at least reviewed the patch and has indicated
    acceptance.  Hence patch mergers will sometimes manually convert
    an acker's "yep, looks good to me" into an Acked-by:  (but note
    that it is usually better to ask for an explicit ack).

    Acked-by:  does not necessarily indicate acknowledgement of the
    entire patch.  For example, if a patch affects multiple subsystems
    and has an Acked-by:  from one subsystem maintainer then this
    usually indicates acknowledgement of just the part which affects
    that maintainer's code.  Judgement should be used here.  When in
    doubt people should refer to the original discussion in the
    mailing list archives.

However, for the kernel project, "Acked-by" is definitely not as
strong as "Reviewed-by":

    Reviewed-by:, instead, indicates that the patch has been reviewed
    and found acceptable according to the Reviewer's Statement:

    Reviewer's statement of oversight

    By offering my Reviewed-by:  tag, I state that:

	a. I have carried out a technical review of this patch to
	   evaluate its appropriateness and readiness for inclusion
	   into the mainline kernel.

	b. Any problems, concerns, or questions relating to the patch
	   have been communicated back to the submitter.  I am
	   satisfied with the submitter's response to my comments.

	c. While there may be things that could be improved with this
	   submission, I believe that it is, at this time, (1) a
	   worthwhile modification to the kernel, and (2) free of
	   known issues which would argue against its inclusion.

	d. While I have reviewed the patch and believe it to be
	   sound, I do not (unless explicitly stated elsewhere) make
	   any warranties or guarantees that it will achieve its
	   stated purpose or function properly in any given situation.

    A Reviewed-by tag is a statement of opinion that the patch is an
    appropriate modification of the kernel without any remaining
    serious technical issues.  Any interested reviewer (who has done
    the work) can offer a Reviewed-by tag for a patch.  This tag
    serves to give credit to reviewers and to inform maintainers of
    the degree of review which has been done on the patch. 
    Reviewed-by:  tags, when supplied by reviewers known to understand
    the subject area and to perform thorough reviews, will normally
    increase the likelihood of your patch getting into the kernel.

For the GDB project, I have been thinking of "Approved-by" as meaning
"Reviewed-by"-with-approval.  But I don't think that should
necessarily be the case.  I think it makes sense for a global
maintainer to see that there are "Reviewed-by" and possibly "Acked-by"
tags and then make a decision to approve the patch (giving it an
"Approved-by" tag) without necessarily having done a detailed analysis
(i.e.  review) themselves.

I understand what you mean, and I see where I may have misunderstood 
when I said that "Acked-By" worked as partial review in QEMU.

I'm fine with this being the default if everyone agrees with it. To 
summarize informally, the tags would be like this:

* Acked-By: A maintainer of a certain area looked at the patch 
description and is fine with its direction. this says nothing about the 
quality of the code. May be restricted to some areas of the code
* Reviewed-By: A contributor has looked at the code and thinks it is 
good, but is not approving it for any reason. May be restricted to some 
areas of the code.
* Approved-By: A maintainer has looked at the code and thinks that it is 
ready for upstreaming. May be restricted to some areas, and may be 
conditional on receiving a review or ack for some area(s).

This makes sense, but it feels more like some informal thing to be 
decided between maintainers.

I like this use of Acked-By, it matches the meaning I thought it had,
based on what other projects do.  It happens that we say something like
"I gave it a quick look and it looks fine to me", indicating that we did
not do a thorough review, in which case Acked-By is appropriate.

Hi,

For the record, I am fine with this direction.

Best,
Lancelot.

[PING][PATCH v5 0/1] update MAINTAINERS file with git trailers

[Guinevere Larsen]

Ping!

There has been some thoughts that this newest direction wasn't the best 
(see Kevin's emails). I would like some more discussion on which 
direction to take the text with regards to approved-by and acked-by 
before sending a new version.
