[U-Boot] checkpatch compliance

[Joe Hershberger]

Hi Wolfgang,

I'm attempting to make the files I touched in several recent
patch-series chechkpatch.pl compliant.

I've hit several cases which fail and probably shouldn't.  For each of
these cases, should the warning / error just be ignored or reported to
checkpatch maintainers or altered some other way?

ERROR: Macros with multiple statements should be enclosed in a do - while loop
+#define CONFIG_SYS_I2C_NOPROBES        { {0, 0x51} } /* Don't probe
these addrs */

static struct
{
        uchar   bus;
        uchar   addr;
} i2c_no_probes[] = CONFIG_SYS_I2C_NOPROBES;

Dear Joe Hershberger,

In message <CANr=Z=Y+Q6AoJ-+gkc+YDeAPGcLsaQkPCzAmhJcRNwts9jXJzw@mail.gmail.com> you wrote:

Please see this message / thread:

http://thread.gmane.org/gmane.linux.kernel/1130494/focus=1172475

It would be best if we
1) copied the current checkpatch.pl from Linux to tools/checkpatch.pl
   (which would also make it easier for all to use the same version)
and
2) provide a customized U-Boot specific .config file that takes care
   about things like the ones you list.

> ERROR: need consistent spacing around '/' (ctx:WxV)

Actually this is IMO wrong.  Should it not be "/nfs/root/path"
instead?

> ERROR: Macros with complex values should be enclosed in parenthesis

Ditto here.

I think this one should actually be reported.

Best regards,

Wolfgang Denk

the only things checkpatch.pl uses $tree for, i think we want.  like #include 
asm/foo.h instead of linux/foo.h.  why do you want this ?

i think these checks are good actually.  we import headers from Linux all the 
time ...

Why depend on or have to specify where a linux tree is for building u-boot?

These seem to be irrelevant if --no-tree is specified.  It doesn't
seem like checkpatch would make good decisions about this anyway given
that an include file that exists in the referred-to Linux tree may not
exist in the u-boot tree.

that's not how it works.  use the u-boot tree as the "linux" tree.

use the u-boot tree, then it works fine

With the latest version of checkpatch that does not work... checkpatch
looks for the following files/folders to identify the
top_of_kernel_tree:

                "COPYING", "CREDITS", "Kbuild", "MAINTAINERS", "Makefile",
                "README", "Documentation", "arch", "include", "drivers",
                "fs", "init", "ipc", "kernel", "lib", "scripts",

u-boot has no Kbuild, Documentation, init, ipc, kernel, or scripts.

i guess let's talk to lkml to see about decoupling this so that only the 
required paths get checked for the relevant tests.  for the header tests, that 
should only require include/linux/ to exist.

Is this list of exceptions reasonable to you?  Should I be looking to
ignore or not ignore anything else?

Potentially it should be a defined as string literal in the future.
It is currently expected to not be a string in common/env_embedded.c,
common/env_common.c, and tools/env/fw_env.c where it uses MK_STR.
Potentially a future cleanup could change all of these references,
however it would break any external definitions of CONFIG_ROOTPATH
that may be passed in from the environment (expecting the MK_STR).

This seems to be local to these files and can be made into a string literal.

no.  please look at all the code that uses MK_STR() in the tree.

Yes.  The MK_STR() should be cleaned up as well, of course.

some of these can be converted away (like CONFIG_ROOTPATH), but MK_STR() 
itself cannot go away as we have some defines which normally get used as 
numbers but we want to embed as a string into the env.  like CONFIG_BAUDRATE.

back to the topic at hand, i don't think we should be keeping out new board 
ports because a much larger tree-wide issue exists.  cleaning up things like 
CONFIG_ROOTPATH, while i think is fine, is non-trivial for most people, and is 
certainly way more than the new or even semi-regular contributor can tackle.

perhaps we should start a top level TODO file where we can start logging all 
the known items we want to get done, and for people who feel like tackling 
something crazy, they can pick off items from there.  and for people who are 
submitting new boards and see these warnings, they can consult the top level 
TODO to see that "ok, it's a known issue, but i can ignore it in my specific 
patchset for now".

I did not intend to suggest to remove MK_STR()

ah, i vaguely recalled seeing something in the past, but couldn't find it in 
the source tree.  maybe a dummy TODO file that just said:
	please visit http://www.denx.de/wiki/U-Boot/Tasks
would be good ?

Every revolutionary idea - in science, politics, art, or  whatever  -
evokes three stages of reaction in a hearer:
  1. It is completely impossible - don't waste my time.
  2. It is possible, but it is not worth doing.
  3. I said it was a good idea all along.

Hi Wolfgang,

I've run into a few more that may be candidates to ignore.

WARNING:CONSIDER_KSTRTO: consider using kstrto* in preference to simple_strtoul
This one seems pretty clear and has been discussed before.

WARNING:NEW_TYPEDEFS: do not add new typedefs
This seems rather limiting... I'm not sure why even Linux would want
this, at least when it applies to typedefs of structs.  It makes sense
if it's a new typedef for int or something.

WARNING:VOLATILE: Use of volatile is usually wrong: see
Documentation/volatile-considered-harmful.txt
Sometimes using volatile is correct... not sure how this fits in with
a policy of 0 errors and 0 warnings...  Should it be ignored or not?

Thanks,
-Joe

i think we were going to add a .checkpatch.conf to the top level where we 
could add all the ignored tests

Linux has been discouraging new struct typedefs.  but it is too broad and 
catches typedefs that we want (like posix_types.h).

"it depends".  we'll have to see the specific instance.

So it's a candidate to ignore, right?

That's what I was getting at... should we ignore it in checkpatch and
simply review any new volatile variables?  Or should we not ignore it
in checkpatch and have exceptions to "no errors, no warnings"?

I also think that for code cleanup where progress can be incremental,
the rules may need to be a little more lenient.

Thanks,
-Joe

it's like the volatiles check.  reviewed on a case by case basis.

if checkpatch ignores it, people won't notice

i've always advocated not using checkpatch this way.  it's simply another tool 
which has known bugs and doesn't cover realistic nuances.

See the CodingStyle, start reading at "It's a _mistake_ to use typedef
for structures and pointers."

There are very, very few cases where a volatile is actually OK, and
these should be hiddenin the lowese levels of the implementation.  In
all cases where we are dealing with device I/O and similar, the
volatile shall be removed, and proper I/O accessors be used instead
(these may then actually use volatile pointer accesses internally, but
usually they don't need to either).

Best regards,

Wolfgang Denk

What is wrong with something like:

ERROR: do not initialise statics to 0 or NULL
#35: FILE: serial.c:32:
+static struct serial_device *serial_devices = NULL;

ERROR: do not initialise statics to 0 or NULL
#36: FILE: serial.c:33:
+static struct serial_device *serial_current = NULL;

Since it's a bootloader, should we also ignore it with:

--ignore INITIALISED_STATIC

Or maybe not?

Thanks,
Gerlando

Why?  Why don't you just follow the advise and remove the redundant
initializers?

Sorry, I didn't realize it had to do with redundancy, the message was 
somewhat unclear to me.
I thought the complaint meant something like "you should initialize 
statics somewhere else", which, in fact, would not make any sense, in 
ANY context.

I personally would prefer an explicit initialization though, like mama 
told me to ALWAYS do... wash your hands before you eat, brush your teeth 
after. (I also like to believe I'm not the only one who had never read 
ISO/IEC 9899 ?6.7.8#2). :-)

newer gcc is smart enough to put these into .bss.  i think older ones were not 
and put these into .data.  in either case, the initialization is redundant (by 
virtue of the "static"), so i'd just drop the "= NULL".
