If set, use the environment variable GIT_DIR to change the default .git location of the kernel git tree.
If GIT_DIR is unset, keep using the current ".git" default. Signed-off-by: Joe Perches <j...@perches.com> --- V2: learn to type my own email address... commit f5f613259f3f ("checkpatch: allow not using -f with files that are in git") breaks the use of checkpatch with: Global symbol "$gitroot" requires explicit package name (did you forget to declare "my $gitroot"?) at ./scripts/checkpatch.pl line 980. Execution of ./scripts/checkpatch.pl aborted due to compilation errors. An unsigned test patch exists in -next that is required for that new commit. So, provide a better commit description for that test patch and sign it too... scripts/checkpatch.pl | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) diff --git a/scripts/checkpatch.pl b/scripts/checkpatch.pl index f40a81f24d43..a213cdb82ab0 100755 --- a/scripts/checkpatch.pl +++ b/scripts/checkpatch.pl @@ -43,6 +43,8 @@ my $list_types = 0; my $fix = 0; my $fix_inplace = 0; my $root; +my $gitroot = $ENV{'GIT_DIR'}; +$gitroot = ".git" if !defined($gitroot); my %debug; my %camelcase = (); my %use_type = (); @@ -908,7 +910,7 @@ sub is_maintained_obsolete { sub is_SPDX_License_valid { my ($license) = @_; - return 1 if (!$tree || which("python") eq "" || !(-e "$root/scripts/spdxcheck.py") || !(-e "$root/.git")); + return 1 if (!$tree || which("python") eq "" || !(-e "$root/scripts/spdxcheck.py") || !(-e "$gitroot")); my $root_path = abs_path($root); my $status = `cd "$root_path"; echo "$license" | python scripts/spdxcheck.py -`; @@ -926,7 +928,7 @@ sub seed_camelcase_includes { $camelcase_seeded = 1; - if (-e ".git") { + if (-e "$gitroot") { my $git_last_include_commit = `${git_command} log --no-merges --pretty=format:"%h%n" -1 -- include`; chomp $git_last_include_commit; $camelcase_cache = ".checkpatch-camelcase.git.$git_last_include_commit"; @@ -954,7 +956,7 @@ sub seed_camelcase_includes { return; } - if (-e ".git") { + if (-e "$gitroot") { $files = `${git_command} ls-files "include/*.h"`; @include_files = split('\n', $files); } @@ -987,7 +989,7 @@ sub git_is_single_file { sub git_commit_info { my ($commit, $id, $desc) = @_; - return ($id, $desc) if ((which("git") eq "") || !(-e ".git")); + return ($id, $desc) if ((which("git") eq "") || !(-e "$gitroot")); my $output = `${git_command} log --no-color --format='%H %s' -1 $commit 2>&1`; $output =~ s/^\s*//gm; @@ -1026,7 +1028,7 @@ my $fixlinenr = -1; # If input is git commits, extract all commits from the commit expressions. # For example, HEAD-3 means we need check 'HEAD, HEAD~1, HEAD~2'. -die "$P: No git repository found\n" if ($git && !-e ".git"); +die "$P: No git repository found\n" if ($git && !-e "$gitroot"); if ($git) { my @commits = ();
