[Qemu-devel] [PATCH v3 0/4] trace-events: print 0x before hex numbers

[Vladimir Sementsov-Ogievskiy]

Hi all!

It is hard to read logs, when there are hex and dec numbers in one line, when
hex number doesn't contain any letters and don't have '0x' prefix.

So, here is a complete solution for the problem:

- add information into CODING_STYLE
- add a check into checkpatch.pl
- fix current state

The new rule for the style is:

Hex numbers should be prefixed by '0x', except groups of numbers,
separated by symbols ' ', '.', ':', '/', however '0x' can be used for
numbers in such groups too. Flag '#' in number format is not allowed.

Note: checkpatch fails on checkpatch change (03) due to long lines.
It is because checkpatch.pl is indented by tabs and when it checks
for long lines it consider tabs as 8 spaces. Looks like nobody cares,
so do I. I see two ways here:
 -  s/\t/    /g
 -  make exclusion in checkpatch.pl for checkpatch.pl to consider tabs
    as 4 spaces, not 8.  However I don't want to fix it in the context
    of these series.

v3: 01 - rewording
    02 - adjust commit message - add two printf flags "'I" into a check
         add Stefan's and Eric's r-bs
    03 - fix commit message s/Accordingly/According/
         add Stefan's r-b
    04 - add Stefan's r-b
         add Cornelia's a-b
v2: almost everything (style, checkpatch, excluding number groups)
V1: was a draft of the idea using two sed commands.

+
+8. trace-events style
+
+8.1 0x prefix
+
+In trace-events files, use a '0x' prefix to specify hex numbers, as in:
+
+some_trace(unsigned x, uint64_t y) "x 0x%x y 0x" PRIx64
+
+An exception is made for groups of numbers that are hexadecimal by
+convention and separated by the symbols '.', '/', ':', or ' ' (such as
+PCI bus id):
+
+another_trace(int cssid, int ssid, int dev_num) "bus id: %x.%x.%04x"
+
+However, you can use '0x' for such groups if you want. Anyway, be sure that
+it is obvious that numbers are in hex, ex.:
+
+data_dump(uint8_t c1, uint8_t c2, uint8_t c3) "bytes (in hex): %02x %02x %02x"
+
+Rationale: hex numbers are hard to read in logs when there is no 0x prefix,
+especially when (occasionally) the representation doesn't contain any letters
+and especially in one line with other decimal numbers. Number groups are allowed
+to not use '0x' because for some things notations like %x.%x.%x are used not
+only in Qemu. Also dumping raw data bytes with '0x' is less readable.
+
+8.2 '#' printf flag
+
+Do not use printf flag '#', like '%#x'.
+
+Rationale: there are two ways to add a '0x' prefix to printed number: '0x%...'
+and '%#...'. For consistency the only one way should be used. Arguments for
+'0x%' are:
+ - it is more popular
+ - '%#' omits the 0x for the value 0 which makes output inconsistent

[Qemu-devel] [PATCH v3 2/4] trace-events: fix code style: %# -> 0x%

[Vladimir Sementsov-Ogievskiy]

In trace format '#' flag of printf is forbidden. Fix it to '0x%'.

This patch is created by the following:

check that we have a problem
> find . -name trace-events | xargs grep '%#' | wc -l
56

check that there are no cases with additional printf flags before '#'
> find . -name trace-events | xargs grep '%[-+ 0'I]+#' | wc -l
0

check that there are no wrong usage of '#' and '0x' together
> find . -name trace-events | xargs grep '0x%#' | wc -l
0

fix the problem
> find . -name trace-events | xargs sed -i 's/%#/0x%/g'

That's not the actual command you used; maintainer can fix the typo by
using "%[-+ 0'I]+#" instead.

Aha yes, you are right. I've checked out the previous commit, checked it 
by a command with "%[-+ 0'I]+#"
and then separately fixed the commit message, forgotten to s/'/"/.

Yes, if a new version will not be required, fix this inflight please.

[Qemu-devel] [PATCH v3 3/4] checkpatch: check trace-events code style

[Vladimir Sementsov-Ogievskiy]

According to CODING_STYLE, check that in trace-events:
1. hex numbers are prefixed with '0x'
2. '#' flag of printf is not used
3. The exclusion from 1. are period-separated groups of numbers

[Qemu-devel] [PATCH v3 4/4] trace-events: fix code style: print 0x before hex numbers

[Vladimir Sementsov-Ogievskiy]

The only exception are groups of numers separated by symbols
'.', ' ', ':', '/', like 'ab.09.7d'.

This patch is made by the following:

> find . -name trace-events | xargs python script.py

where script.py is the following python script:
=========================
 #!/usr/bin/env python

import sys
import re
import fileinput

rhex = '%[-+ *.0-9]*(?:[hljztL]|ll|hh)?(?:x|X|"\s*PRI[xX][^"]*"?)'
rgroup = re.compile('((?:' + rhex + '[.:/ ])+' + rhex + ')')
rbad = re.compile('(?<!0x)' + rhex)

files = sys.argv[1:]

for fname in files:
    for line in fileinput.input(fname, inplace=True):
        arr = re.split(rgroup, line)
        for i in range(0, len(arr), 2):
            arr[i] = re.sub(rbad, '0x\g<0>', arr[i])

        sys.stdout.write(''.join(arr))
