[PATCH 0/6] patman: Small fixes plus remove --no-tree from checkpatch for linux

[Douglas Anderson]

The whole point of this series is really to make it so that when we're
using patman for sending Linux patches that we don't pass "--no-tree"
to checkpatch. While doing that, though, I found a number of bugs
including an explanation about why recent version of patman have been
yelling about "tags" when used with Linux even though Linux is
supposed to have "process_tags" defaulted to False.


Douglas Anderson (6):
  patman: Fix updating argument defaults from settings
  patman: Fix implicit command inserting
  patman: Don't look at sys.argv when parsing settings
  patman: Make most bool arguments BooleanOptionalAction
  patman: By default don't pass "--no-tree" to checkpatch for linux
  patman: Take project defaults into account for --help

[PATCH 1/6] patman: Fix updating argument defaults from settings

[Douglas Anderson]

Ever since commit 4600767d294d ("patman: Refactor how the default
subcommand works"), when I use patman on the Linux tree I get grumbles
about unknown tags. This is because the Linux default making
process_tags be False wasn't working anymore.

It appears that the comment claiming that the defaults propagates
through all subparsers no longer works for some reason.

We're already looking at all the subparsers anyway. Let's just update
each one.

Fixes: 4600767d294d ("patman: Refactor how the default subcommand works")

[PATCH 2/6] patman: Fix implicit command inserting

[Douglas Anderson]

The logic to insert an implicit command has always been a bit broken
but it was masked by another bug fixed in the patch ("patman: Don't
look at sys.argv when parsing settings"). Specifically, imagine that
you're just calling patman like this:

  patman -c1

After the parse_known_args() command then the "-c1" will have been
parsed and we'll have no command. The "rest" variable will be an empty
list. Going into the logic you can see that nargs = 0. The implicit
insertion of send ideally would create an argument list of:
  ['-c1', 'send']
...but it doesn't because argv[:-0] is the same as argv[:0] and that's
an empty list.

Let's fix this little glitch.

[PATCH 3/6] patman: Don't look at sys.argv when parsing settings

[Douglas Anderson]

If you call the parser and tell it to parse but don't pass arguments
in then it will default to looking at sys.argv. This isn't really what
was intended and seems to have some side effects. Let's not do it.

NOTE: to see some of the side effects, note that this patch breaks
"patman -c1" if you don't have the patch ("patman: Fix implicit
command inserting") before it.

[PATCH 4/6] patman: Make most bool arguments BooleanOptionalAction

[Douglas Anderson]

For boolean arguments it's convenient to be able to specify both the
argument and its opposite on the command line. This is especially
convenient because you can change the default via the settings file
and being able express the opposite can be the only way to override
things.

Luckily python handles this well--we just need to specify things with
BooleanOptionalAction. We'll do that for all options except
"full-help" (where it feels silly). This uglifies the help text a
little bit but does give maximum flexibility.

I know you mentioned --help ugliness, but this one ends up looking like:

  (default=warn) (default: False)

Perhaps we should drop the baked-in "(default=warn)" text?

Otherwise:

[PATCH 5/6] patman: By default don't pass "--no-tree" to checkpatch for linux

[Douglas Anderson]

When you pass "--no-tree" to checkpatch it disables some extra checks
that are important for Linux. Specifically I want checks like:

  warning: DT compatible string "boogie,woogie" appears un-documented
  check ./Documentation/devicetree/bindings/

Let's make the default for Linux to _not_ pass --no-tree. We'll have a
config option and command line flag to override.

[PATCH 6/6] patman: Take project defaults into account for --help

[Douglas Anderson]

I'd like it so that when you do "patman send --help" and you're using
Linux that it show it the proper defaults for Linux.

The previous bullet has a "second", and so does this one. Are those
different meanings, or are we counting wrong?

This might be a good place to say that this multiple passes on argparse
is very confusing to me. That's not to say that you need to explain it

Awesome, I've been annoyed by the 'tags' thing, and just go used to
