From 9c9ba34ee3dbc34e829f42e42a5e5273b1183500 Mon Sep 17 00:00:00 2001 From: Andy Whitcroft Date: Tue, 29 Apr 2008 00:59:33 -0700 Subject: [PATCH] update checkpatch.pl to version 0.18 This version brings a few fixes for the extern checks, and a couple of new checks. Of note: - false is now recognised as a 0 assignment in static/external assignments, - printf format strings including %L are reported, - a number of fixes for the extern in .c file detector which had temporarily lost its ability to detect variables; undetected due to the loss of its test. Andy Whitcroft (8): Version: 0.18 false should trip 0 assignment checks tests: reinstate missing tests tests: allow specification of the file extension for a test fix extern checks for variables check for and report %Lu, %Ld, and %Li ensure we only start a statement on lines with some content extern spacing Signed-off-by: Andy Whitcroft Cc: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- scripts/checkpatch.pl | 25 ++++++++++++++++++++----- 1 file changed, 20 insertions(+), 5 deletions(-) diff --git a/scripts/checkpatch.pl b/scripts/checkpatch.pl index fd21b5eaed3..b6bbbcdc557 100755 --- a/scripts/checkpatch.pl +++ b/scripts/checkpatch.pl @@ -9,7 +9,7 @@ use strict; my $P = $0; $P =~ s@.*/@@g; -my $V = '0.17'; +my $V = '0.18'; use Getopt::Long qw(:config no_auto_abbrev); @@ -1144,7 +1144,7 @@ sub process { # Check for potential 'bare' types my ($stat, $cond); - if ($realcnt) { + if ($realcnt && $line =~ /.\s*\S/) { ($stat, $cond) = ctx_statement_block($linenr, $realcnt, 0); $stat =~ s/\n./\n /g; @@ -1316,12 +1316,12 @@ sub process { } # check for external initialisers. - if ($line =~ /^.$Type\s*$Ident\s*=\s*(0|NULL);/) { + if ($line =~ /^.$Type\s*$Ident\s*=\s*(0|NULL|false)\s*;/) { ERROR("do not initialise externals to 0 or NULL\n" . $herecurr); } # check for static initialisers. - if ($line =~ /\s*static\s.*=\s*(0|NULL);/) { + if ($line =~ /\s*static\s.*=\s*(0|NULL|false)\s*;/) { ERROR("do not initialise statics to 0 or NULL\n" . $herecurr); } @@ -1973,7 +1973,7 @@ sub process { # check for new externs in .c files. if ($realfile =~ /\.c$/ && defined $stat && - $stat =~ /^.(?:extern\s+)?$Type\s+$Ident(\s*)\(/s) + $stat =~ /^.\s*(?:extern\s+)?$Type\s+$Ident(\s*)\(/s) { my $paren_space = $1; @@ -1988,6 +1988,11 @@ sub process { if ($paren_space =~ /\n/) { WARN("arguments for function declarations should follow identifier\n" . $herecurr); } + + } elsif ($realfile =~ /\.c$/ && defined $stat && + $stat =~ /^.\s*extern\s+/) + { + WARN("externs should be avoided in .c files\n" . $herecurr); } # checks for new __setup's @@ -2033,6 +2038,16 @@ sub process { { WARN("usage of NR_CPUS is often wrong - consider using cpu_possible(), num_possible_cpus(), for_each_possible_cpu(), etc\n" . $herecurr); } + +# check for %L{u,d,i} in strings + my $string; + while ($line =~ /(?:^|")([X\t]*)(?:"|$)/g) { + $string = substr($rawline, $-[1], $+[1] - $-[1]); + if ($string =~ /(?
