[PATCH v3 0/5] 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.

Changes in v3:
- Rebased atop ("patman: Fix defaults not propagating to subparsers")

Changes in v2:
- Fix doc string for --ignore-bad-tags
- Make comment about parsing three times less nonsensical.

Douglas Anderson (5):
  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 v3 1/5] 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 v3 2/5] 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 v3 3/5] 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.

[PATCH v3 4/5] 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.

Sadly this patch triggers an error:

I've dropped it and the next one. Can you please take a look?

Ugh. I hadn't noticed that it was added in python 3.9. I guess we
don't want to require python 3.9+? Python 3.9 was released October
2020...

Re: [PATCH v3 5/5] patman: Take project defaults into account for --help

[Simon Glass]

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.

Re: [PATCH v3 1/5] patman: Fix implicit command inserting

[Simon Glass]

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.

Re: [PATCH v3 2/5] patman: Don't look at sys.argv when parsing settings

[Simon Glass]

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.

Not yet! It might be possible to do a little compatibility thing. We
do sometimes have code that does things the old way and the new way.
But it might be too intrusive in this case?
