[PATCH] get_maintainer: Don't fallback to git by default

[PATCH] get_maintainer: Don't fallback to git by default

[Javier Martinez Canillas]

The get_maintainer.pl script could be used to get a list of people that
has to be in the copy list when posting patches for a given file but it
defaults to git fallback so the list returned isn't really relevant and
submitters are posting patches to random developers that just happened
to touch that file in the past.

Disable git fallback so get_maintainer.pl only returns the information
that is in MAINTAINERS by default.

Hello,

This patch was suggested by Wolfram on this thread [0] but it is
something I thought before because I've seen people complaining
on a regular basis about being cc'ed in random patches and there
are tools like patman [1] that rely on get_maintainers.pl to post
the patches.

We might need to do a sweep of files to make sure more of them are
listed in the maintainers file, else by default they only show LKML.
As an example, a bunch of files in lib are only showing LKML.
Defaulting to only sending to LKML may be swinging too far in the wrong
direction for reducing inbox size.

Hello Laura,

Thanks a lot for your feedback.

You are correct, disabling git fallback could be a too radical solution
for now until the MAINTAINERS file is more complete.

I'll do some auditing to the files in the source tree and see if I can
come with a patch series that improves the state of MAINTAINERS before
disabling this option by default.

What if we have a git_fallback "auto" mode which only falls back to
using git if there is no entry in the MAINTAINERS file?  That might
address the concern which Laura raised, without blocking this
change until the MAINTAINERS file is fully populated.

Cheers,

That's what happens already right now.

I think it can be done better.

FYI, this patch came about because I keep complaining about submitters
sending me patches I really shouldn't have to care about.

Here is the most recent offending command output:

Anyone south of Wolfram and north of the I2C ML is unlikely to care.

Please find a way to make this better.  For the sake of our sanity.

Actually, driver maintainers should care about their portion of it.
Which leads me to the conclusion that driver maintainer entries in
MAINTAINERS should have the relevant Kconfig symbol as a keyword match,
probably.

Good point, well put.  Although this situation is fairly unique to
Kconfig changes.  In general I know I don't want to be spammed with
changes to all the files I've ever adapted though.  If people wish to
act as reviewers, they should have a mention in MAINTAINERS for
get_maintiner.pl to pull information from:

R: Designated reviewer: FullName <address@domain>
   These reviewers should be CCed on patches.

Or a new marker, I: Interested parties.

I think this should do.

Interested parties should start by scanning the mailing list :)

I think the concept of reviewers is fine.

A couple weeks ago, I suggested a mechanism to have reviewers
concentrate their entries into separate REVIEWERS file(s)

https://lkml.org/lkml/2015/10/16/649

These REVIEWERS* files would also work for companies that have
people with specific areas of expertise that want internal review
before public exposure.

Kconfig and Makefile files in directories like drivers/i2c/busses
are outliers because all new individual drivers are added to both
files.

The mechanism to limit git-fallback use is a directory depth match.

Wolfram has a MAINTAINERS entry of:
	F:	drivers/i2c/
but that doesn't pattern doesn't match the directory depth of
file drivers/i2c/busses/Kconfig so git-fallback is used for files
that don't have specific MAINTAINERS.

It _might_ make some sense to limit activation of git history in
that specific case, but for some path like arch/, that limitation
might _not_ make sense.

Another option would be to add another pattern to the
I2C section that matches all subdirectories of drivers/i2c/:
---
 MAINTAINERS | 1 +
 1 file changed, 1 insertion(+)

Hmm, what would be the drawback of extending the meaning of
'drivers/i2c/' to include 'drivers/i2c/*/'? To be honest, I assumed it
works this way already and I'd think I am not alone with that
assumption.

Thanks for looking into this!

Some top level directories contain other subsystems.

A maintainer of something like arch/arm doesn't generally
want to be the maintainer of arch/arm/mach-<foo>

You _want_ a wider number of reviewers for patches to any
of those unmaintained subsystems.

I agree.

+F:	drivers/i2c/*/

makes sense then.

The listing does become a bit unwieldy when there are
multiple sublevel directories.

It'd probably be nicer syntax to have some ... type
marking, but the number of cases just isn't very high
and most likely not worth the effort to me.

As both of my most recent issues have been pertaining to
drivers/i2c/*/ this would solve my current issue.  If anything else
crops up I'll be sure to let you know. ;)

Then you should add your name to the .get_maintainer.ignore file.

If you do, you'll only get listed by get_maintainer for files where
you have a specific entry in MAINTAINERS.

Oooo... I didn't even know that existed.  It's an idea, but I'd rather
have these kinds of issues sorted out for everyone, rather than being
a special case and putting myself in the grumpy-old-b***** file.  I'm
certainly not the only one suffering with this problem.

I agree with Lee here, if everyone has to be added to a file then that
solution does not scale. I bet that no one working on the kernel would
say that is OK on receiving random patches.

Another option is to bump the git-fallback min % used as a threshold,
for example when using a min value of 20 the list is more sensible:

$ ./scripts/get_maintainer.pl -f --git-min-percent=20 drivers/i2c/busses/Kconfig 
Wolfram Sang <wsa@the-dreams.de> (maintainer:I2C SUBSYSTEM,commit_signer:26/26=100%,removed_lines:3/11=27%)
linux-i2c@vger.kernel.org (open list:I2C SUBSYSTEM)
linux-kernel@vger.kernel.org (open list)

Is not only Lee tbh, I see people complaining almost on a daily so
the current default is not good enough. This of course annoys more
to maintainers that already have a very heavy email load but it is
also inconvenient for developers like me since by doing a change
on a file that is frequently modified (i.e: Makefile, Kconfig, etc)
you earn a life of spam :)
