Update of:
v2: https://lists.gnu.org/archive/html/qemu-devel/2022-07/msg00595.html
The first patch gives a detailed description, but the overall goal
here is to provide a code style checking facility to augment (and
ideally replace) checkstyle.pl. The key conceptual differences are:
- Always applies to all code in tree, not merely patches
- Failures are always fatal, exceptions must be recorded
- Always runs as part of 'make check'
The first patch introduces the infrastructure, the remaining patches
illustrate its uses for some rules where we currently have violations
- Prevent initializing an 'int' variable with 'true' / 'false'
- Look for commonly repeated words (ie the the)
- Ensure qemu/osdep.h is listed first in all .c files
- Ensure qemu/osdep.h is NOT listed in .h or .c.inc file
As noted above, it integrates with 'make check' via a new test suite
called 'style', so you can invoke it individually too:
$ make check-style
changing dir to build for make "check-style"...
/usr/bin/meson test --no-rebuild -t 0 --num-processes 1 --print-errorlogs --suite style
1/3 qemu:style / int_assign_bool OK 0.28s
2/3 qemu:style / prohibit_doubled_word OK 1.78s
3/3 qemu:style / c_file_osdep_h OK 0.08s
Ok: 3
Expected Fail: 0
Fail: 0
Unexpected Pass: 0
Skipped: 0
Timeout: 0
Example of what it looks like when it fails:
$ make check-style
changing dir to build for make "check-style"...

The speed of the test suite is largely driven by how quickly
'grep' / 'perl' can match through *every* file in the source
tree (as reported by 'git ls-tree'). Certain regex expressions
can affect this by causing lots of backtracking, but generally
each test is expected to be < 1 second for the whole source tree.
Changed in v3:
- Got rid of all the makefile usage, writing the test logic
in python, and defining the tests in a YAML file. Logically
it is doing the same as before, but should be more easy
to understand.
- Check that osdep.h is /first/, not merely present, identifying
a few more violations in tree.
- Check that osdep.h is NOT in .h or .c.inc files, identifynig
even more violations in tree.
- Fixed a few of the fixes in the source
Daniel P. Berrangé (9):
tests: introduce tree-wide code style checking
misc: fix mixups of bool constants with int variables
tests/style: check for mixups of bool constants with int variables
misc: fix commonly doubled up words
tests/style: check for commonly doubled up words
misc: ensure qemu/osdep.h is included first in all .c files
tests/style: check qemu/osdep.h is included in all .c files
misc: remove qemu/osdep.h from headers / included source files

Historically QEMU has used the 'scripts/checkpatch.pl' script to
validate various style rules but there are a number of issues:
- Contributors / maintainers are reluctant to add new
tests to it, nor fix existint rules, because the Perl
code is much too hard to understand for most people.
- It requires the contributor to remember to run it as it
is not wired into 'make check'
- While it can be told to check whole files, in practice
it is usually only used to check patch diffs, because the
former would flag up pages of pre-existing violations that
have never been fixed
- It is said to be OK to ignore some things reported by the
script, but don't record these exceptional cases anywere.
Thus contributors looking at existing violations in tree
are never sure whether they are intentional or historical
unfixed technical debt.
- There is no distinct reporting for each type of check
performed and as a consequence there is also no way to
mark particular files to be skipped for particular checks
This commit aims to give us a better approach to checking many
types of code style problems by introducing a flexible and simple
way to define whole tree style checks.
The logic provide is inspired by the GNULIB 'top/maint.mk' file,
but has been re-implemented in a simple Python script, using a
YAML config file, in an attempt to make it easier to understand
than the make rules.
This commit does the bare minimum introducing the basic infra:
- tests/style.py - the script for evaluating coding style rules
- tests/style.yml - the config defining the coding style rules
The concept behind the style checking is to perform simple regular
expression matches across the source file content.
The key benefit of regular expression matching is that it is very
fast, and can match against all types of source file in the repository,
regardless of whether it is used in the current build, or the language
the source is written in.
The downside, compared to a compiler based approach (eg libclang) is
that it does not have semantic understanding of the code, which makes
some checks difficult to implement.
As such this style matching framework is not proposed as a solution for
all possible coding style rules. It is general enough that it can
accomplish many useful checks, and is intended to be complimentary to
any style checkers with semantic knowledge of the code like libclang,
or pylint/flake8.
It would be possible to use Python's regular expression engine to
perform this matching directly, it instead calls out to 'grep' (for
single line matches) and 'perl' (for multiline matches). These are
highly optimized regex engines, so should maximise performance. They
also avoid problems with python's charset encoding causing it to
throw exceptions when encountering invalid utf8, rather than continue
on a best effort basis.
In terms of defining checks, a short bit of yaml is all that is
required. For example, consider we want to stop people using the
'bool' type entirely in C source files. A rule in tests/style.yml
would say
prohibit_bool:
files: \.c$
prohibit: \bbool\b
message: do not use the bool type
The 'prohibit' rule is matched line-wise across every .c source
file. If any violation is found, the contents of that line are
printed, and 'message' is shown as a error message.
There are many more advanced options, which are documented in
comments in the style.yml file in this commit.
The tool can be invoked directly
./tests/style.py --config test/style.yml check
Or for individual checks
./tests/style.py --config test/style.yml check --rule prohibit_bool
If a file is known to intentionally violate a style check rule
this can be recorded in the style.yml and will result in it being
ignored. The '--ignored' flag can be used to see ignored failures.
This is all wired up into meson, such that a 'style' test suite is
defined and each individual style check is exposed as a test case.
This results in creation of a 'make check-style' target that is
triggerd by 'make check' by default.
Note that the checks require the use of 'git' to detect the list of
source files to search. Thus the check is skipped when not running
from a git repository.

The 'true' and 'false' constants should only ever be used with the
'bool' type, never 'int'.

This style check looks for cases where the words
the then in an on if is it but for or at and do to
are repeated in a sentence. It uses a multi-line match to catch the
especially common mistake in docs where the last word on a line is
repeated as the first word of the next line.
There are inevitably be some false positives with this check, for
example, some docs data tables have the same word in adjacent columns.
There are a few different ways to express this text as a regex which
have wildly different execution time. This impl was carefully chosen
to attempt to minimize matching time.

A few files relied on qemu/osdep.h being included via a common
header. Others didn't need it because they were actually an
included file, so ought to have been named '.c.inc'. Finally
some didn't have it as the first header included.

The qemu/osdep.h file must be included as the very first header in
all C source files, to ensure its definitions take effect over all
other header files, including system headers.

Since qemu/osdep.h is guaranteed present in all C source files,
there is hno reason for it to be present in header files. Some
C source files are not directly directly, but rather included
from other source files. These should also not have qemu/osdep.h
present, as the primary source will have already included it.

Why not check .c.inc and .h (for static inlined func)?

So would the intention be that we try to obsolete checkpatch,
or will we still have checkpatch because it can find some
style issues that this framework cannot handle?
I think that on balance I'm in favour of this patchseries if
it is part of a path where we say "we are going to drop
checkpatch and replace it with X, Y and Z" (and we actually
implement that path and don't just end up with another
half-completed transition :-)). I'm much less in favour if
it's just "we added yet another thing to the pile"...

Is it possible to have an individual "suppress this style check
in this one place" mechanism? Dropping an entire file from the
style check is certainly going to be useful for some situations,
but very often I would expect there might be one place in a
multi-thousand line C file where we want to violate a style
rule and it would be nice not to lose the coverage on all the
rest of the file as a result. Plus a whole-file suppression that
lives somewhere other than the source file is going to tend to
hang around for ages after we refactor/delete whatever bit of
source code it was that meant we needed the suppression, whereas
if the suppression is in the source file itself then you see it
when you're working on that bit of code.

I think this should live in scripts/, same as checkpatch.

Should we use Meson's fs.is_dir() rather than running a shell?

I would certainly like to see us eventually remove
checkpatch.pl because of the various downsides it has.
The caveat is that I've not actually looked in any detail
at what things checkpatch.pl actually checks for. Without
looking my guess-timate is that we could probably replace
90% of it without much trouble. Perhaps we'll just decide
some of the checkjs in checkpatch aren't worth the burden
of maintaining its usage.

We could possibly come up with a way to put a magic comment
on the end of a line (eg '// style:ignore' ), and have it applied
automatically as an exclusion. A magic comment the line before
is hard though, given that we're aiming to match things linewise
for speed.

Probably not a good idea as-is; .git need not be a directory, but can
also be a symlink. So 'test -e .git' is the better check (see
scripts/qemu-version.sh); but if you can write an existence check in
meson (instead of a directory check), then go for it.

There is a fs.exists(), yes. I just suggested .is_dir() because
the code as written here is doing a -d check, not a -e check.

Can we add an exception regex as well: the prohibit rule is ignored on
lines that also match the exception rule, allowing us to write a rule
that would recognize magic comments on lines where we intentionally
break the normal rule?

Do we need to make the colorization dependent on whether output is a
terminal or a specific flag is in use?

Unrelated to the patch at hand, but a good example of the issue...
Can we add a style checker to ensure that text files (including
style.yml) end in a trailing newline?

Should we also have a rule that rejects <qemu/osdep.h> in all files
(our only spelling should be with "", not <>)?

I went through checkpatch, and here are the warnings I think
are worth making sure we still have. I've included all the
ones that look like we've added them specifically for QEMU
on the basis that if we cared enough to edit checkpatch to
add them then we ought to care enough to retain them.
* "Do not add expected files together with tests,
follow instructions in tests/qtest/bios-tables-test.c"
* "do not set execute permissions for source files"
* "please use python3 interpreter"
* "Author email address is mangled by the mailing list"
* syntax checks on Signed-off-by lines
* "does MAINTAINERS need updating?"
* "Invalid UTF-8"
* "trailing whitespace"
* "DOS line endings" (maybe)
* "Don't use '#' flag of printf format ('%#') in trace-events"
* "Hex numbers must be prefixed with '0x' [in trace-events]"
* line-length checks (though for a "whole codebase must pass"
test we would want to set the length longer than the current
"author should consider whether to wrap" value
* hard coded tabs
* the various dodgy-indentation checks
* the various space-required checks eg around operators
* misformatted block comments
* "do not use C99 // comments"
* "do not initialise globals/statics to 0 or NULL"
* "do not use assignment in if condition"
* "braces {} are necessary for all arms of this statement"
* "braces {} are necessary even for single statement blocks"
* "Use of volatile is usually wrong, please add a comment"
* "g_free(NULL) is safe this check is probably not required"
* "memory barrier without comment"
* "unnecessary cast may hide bugs, use g_new/g_renew instead"
* "consider using g_path_get_$1() in preference to g_strdup($1())"
* "use g_memdup2() instead of unsafe g_memdup()"
* "consider using qemu_$1 in preference to $1" (strto* etc)
* "use sigaction to establish signal handlers; signal is not portable"
* "please use block_init(), type_init() etc. instead of module_init()"
* "initializer for struct $1 should normally be const"
* "Error messages should not contain newlines"
* "use ctz32() instead of ffs()"
* ditto, ffsl, ffsll, bzero, getpagesize, _SC_PAGESIZE
* "Use g_assert or g_assert_not_reached" [instead of non-exiting glib asserts]
These seem to me to fall into three categories:
(1) many are easy enough to do with grep
(2) there are some checks we really do want to do on the patch,
not on the codebase (most obviously things like Signed-off-by:
format checks)
(3) there are coding style checks that do need to have at least some
idea of C syntax, to check brace placement, whitespace, etc
thanks
