Joe Perches e33c9fe8b8 get_maintainer: fix unexpected behavior for path/to//file (double slashes)
get_maintainer behaves differently if there is a double sequential forward
slash in a filename because the total number of slashes in a filename is
used to match MAINTAINERS file patterns.

For example:

(with double slash)
  $ ./scripts/get_maintainer.pl -f drivers/gpu/drm//lima
  David Airlie <airlied@linux.ie> (maintainer:DRM DRIVERS)
  Daniel Vetter <daniel@ffwll.ch> (maintainer:DRM DRIVERS,commit_signer:3/42=7%)
  Qiang Yu <yuq825@gmail.com> (commit_signer:36/42=86%,authored:24/42=57%)
  Vasily Khoruzhick <anarsoul@gmail.com> (commit_signer:26/42=62%)
  Krzysztof Kozlowski <krzk@kernel.org> (commit_signer:5/42=12%,authored:5/42=12%)
  Emil Velikov <emil.velikov@collabora.com> (commit_signer:4/42=10%)
  dri-devel@lists.freedesktop.org (open list:DRM DRIVERS)
  linux-kernel@vger.kernel.org (open list)

(without double slash)
  $ ./scripts/get_maintainer.pl -f drivers/gpu/drm/lima
  Qiang Yu <yuq825@gmail.com> (maintainer:DRM DRIVERS FOR LIMA)
  David Airlie <airlied@linux.ie> (maintainer:DRM DRIVERS)
  Daniel Vetter <daniel@ffwll.ch> (maintainer:DRM DRIVERS)
  dri-devel@lists.freedesktop.org (open list:DRM DRIVERS FOR LIMA)
  lima@lists.freedesktop.org (moderated list:DRM DRIVERS FOR LIMA)
  linux-kernel@vger.kernel.org (open list)

So reduce consecutive double slashes to a single slash
by using File::Spec->canonpath().

from: https://perldoc.perl.org/File/Spec/Unix.html

canonpath()

No physical check on the filesystem, but a logical cleanup of a path.  On
UNIX eliminates successive slashes and successive "/.".

Joe Perches 0c78c01376 get_maintainer: add email addresses from .yaml files
.yaml files can contain maintainer/author addresses and it seems unlikely
or unnecessary that individual MAINTAINER file section entries for each
.yaml file will be created.

So add the email addresses found in .yaml files to the default
get_maintainer output.

The email addresses are marked with "(in file)" when using the "--roles"
or "--rolestats" options.

Miscellanea:

o Change $file_emails to $email_file_emails to avoid visual
  naming conflicts with @file_emails

Douglas Anderson 0ef82fcefb scripts/get_maintainer.pl: deprioritize old Fixes: addresses
Recently, I found that get_maintainer was causing me to send emails to
the old addresses for maintainers.  Since I usually just trust the
output of get_maintainer to know the right email address, I didn't even
look carefully and fired off two patch series that went to the wrong
place.  Oops.

The problem was introduced recently when trying to add signatures from
Fixes.  The problem was that these email addresses were added too early
in the process of compiling our list of places to send.  Things added to
the list earlier are considered more canonical and when we later added
maintainer entries we ended up deduplicating to the old address.

Here are two examples using mainline commits (to make it easier to
replicate) for the two maintainers that I messed up recently:

  $ git format-patch d8549bcd0529~..d8549bcd0529
  $ ./scripts/get_maintainer.pl 0001-clk-Add-clk_hw*.patch | grep Boyd
  Stephen Boyd <sboyd@codeaurora.org>...

  $ git format-patch 6d1238aa3395~..6d1238aa3395
  $ ./scripts/get_maintainer.pl 0001-arm64-dts-qcom-qcs404*.patch | grep Andy
  Andy Gross <andy.gross@linaro.org>

Let's move the adding of addresses from Fixes: to the end since the
email addresses from these are much more likely to be older.

After this patch the above examples get the right addresses for the two
examples.

Add a command line switch --no-moderated to skip L: mailing lists marked

Some people prefer not emailing moderated mailing lists as the
moderation time can be indeterminate and some emails can be
intentionally dropped by a moderator.

This can cause fragmentation of email threads when some are subscribed
to a moderated list but others are not and emails are dropped.

Kamil Rytarowski cb77f0d623 scripts: Switch to more portable Perl shebang
The default NetBSD package manager is pkgsrc and it installs Perl
along other third party programs under custom and configurable prefix.
The default prefix for binary prebuilt packages is /usr/pkg, and the
Perl executable lands in /usr/pkg/bin/perl.

This change switches "/usr/bin/perl" to "/usr/bin/env perl" as it's
the most portable solution that should work for almost everybody.
Perl's executable is detected automatically.

This change switches -w option passed to the executable with more
modern "use warnings;" approach. There is no functional change to the
default behavior.

While there, drop "require 5" from scripts/namespace.pl (Perl from 1994?).

Richard Genoud ec83b616a7 get_maintainer: fix detection of git repository
Since git v1.7.7, the .git directory can be a file when, for example,
the kernel is a submodule of another git super project.  So, the check
"-d .git" is not working anymore in this case.  Using a more generic
check like "-e .git" corrects this behaviour.

Joe Perches c9ecefea0b get_maintainer: add commit author information to --rolestats
get_maintainer currently uses "Signed-off-by" style lines to find
interested parties to send patches to when the MAINTAINERS file does not
have a specific section entry with a matching file pattern.

Add statistics for commit authors and lines added and deleted to the
information provided by --rolestats.

These statistics are also emitted whenever --rolestats and --git are
selected even when there is a specified maintainer.

This can have the effect of expanding the number of people that are shown
as possible "maintainers" of a particular file because "authors",
"added_lines", and "removed_lines" are also used as criterion for the
--max-maintainers option separate from the "commit_signers".

The first "--git-max-maintainers" values of each criterion
are emitted.  Any "ties" are not shown.

For example: (forcedeth does not have a named maintainer)

Old output:

$ ./scripts/get_maintainer.pl -f drivers/net/ethernet/nvidia/forcedeth.c
"David S. Miller" <davem@davemloft.net> (commit_signer:8/10=80%)

Stephen Warren bbbe96ed89 get_maintainer: use filename-only regex match for Tegra
Create a new N: entry type in MAINTAINERS which performs a regex match
against filenames; either those extracted from patch +++ or --- lines,
or those specified on the command-line using the -f option.

This provides the same benefits as using a K: regex option to match a
set of filenames (see commit eb90d0855b "get_maintainer: allow
keywords to match filenames"), but without the disadvantage that
"random" file content, such as comments, will ever match the regex.
Hence, revert most of that commit.

Switch the Tegra entry from using K: to N:

Stephen Warren eb90d0855b get_maintainer: allow keywords to match filenames
Allow K: entries in MAINTAINERS to match directly against filenames;
either those extracted from patch +++ or --- lines, or those specified
on the command-line using the -f option.

This potentially allows fewer lines in a MAINTAINERS entry, if all the
relevant files are scattered throughout the whole kernel tree, yet
contain some common keyword.  An example would be using an ARM SoC name
as the keyword to catch all related drivers.

I don't think setting exact_pattern_match_hash would be appropriate
here; at least for intended Tegra use case, this feature is to ensure
that all Tegra-related driver changes get Cc'd to the Tegra mailing
list.  Setting exact_pattern_match_hash would prevent git history
parsing for e.g.  S-o-b tags, which still seems like it would be useful.
Hence, this flag isn't set.

parsing to the "---" lines.

Ian Campbell ed128fea3b get_maintainers.pl: follow renames when looking up commit signers
I happen to have had a commit to various network drivers since the big
renaming/reorg which happened to drivers/net recently.  This means that I
now appear to be in the top few commit signers (by %age) for many of them
so am getting sent all sorts of stuff and people who are involved with the
driver are not.  e.g.  (to pick one at random):

        $ ./scripts/get_maintainer.pl -f drivers/net/ethernet/nvidia/forcedeth.c
        "David S. Miller" <davem@davemloft.net> (commit_signer:5/7=71%)
        Ian Campbell <ian.campbell@citrix.com> (commit_signer:2/7=29%)
        Eric Dumazet <eric.dumazet@gmail.com> (commit_signer:1/7=14%)
        Jeff Kirsher <jeffrey.t.kirsher@intel.com> (commit_signer:1/7=14%)
        Jiri Pirko <jpirko@redhat.com> (commit_signer:1/7=14%)
        netdev@vger.kernel.org (open list:NETWORKING DRIVERS)
        linux-kernel@vger.kernel.org (open list)

With the following patch the renames are followed and the result appears
much more sensible:

Turns out this is an arguable defect in the script.

The MAINTAINERS entry for mm is:

MEMORY MANAGEMENT
L:	linux-mm@kvack.org
W:	http://www.linux-mm.org
S:	Maintained
F:	include/linux/mm.h
F:	mm/

There's a maintainer entry, but no named individual, so the script doesn't
use git history via --git-fallback.

This is also a defect for MAINTAINERS with status entries marked "Orphan"
or "Odd fixes".

The script now checks a section for any "M:" entry and that an "S:" entry
is supported or maintained.  If both those conditions are not satisified,
use --git-fallback as appropriate.
