Re^4: File permissions problem (updated)

[wdhammond]

I found this sub in another module (TextUnicode):

# Custom file save routine to handle unicode files
sub SaveUTF {
    my ( $w, $filename ) = @_;
    $filename = $w->FileName unless defined $filename;
    my $dir   = dirname($filename);
    my $perms = ( stat($dir) )[2] & 07777;
    unless ( $perms & 0200 ) {
        $perms = $perms | 0200;
        chmod $perms, $dir
          or $w->BackTrace("Can not write to directory $dir: $!\n")
          and return;
    }
    my ( $tempfh, $tempfilename ) = tempfile( DIR => $dir );
    my $status;
    my $count = 0;
    my $index = '1.0';
    my $progress;
    my $fileend = $w->index('end -1c');
    my ($lines) = $fileend =~ /^(\d+)\./;
    my $unicode = ::currentfileisunicode();
    # No BOM please
    #if ($unicode) {
    #    my $bom = "\x{FEFF}";
    #    utf8::encode($bom);
    #    print $tempfh $bom;
    #}
    while ( $w->compare( $index, '<', $fileend ) ) {
        my $end = $w->index("$index lineend +1c");
        my $line = $w->get( $index, $end );
        $line =~ s/[\t \xA0]+$//;

        #$line = ::eol_whitespace($line);
        $line =~ s/\cM\cJ|\cM|\cJ/\cM\cJ/g if (OS_Win);
        utf8::encode($line) if $unicode;
        $w->BackTrace("Cannot write to temp file:$!\n") and return
          unless print $tempfh $line;
        $index = $end;
        if ( ( $count++ % 1000 ) == 0 ) {
            $progress =
              $w->TextUndoFileProgress( Saving => $filename,
                                        $count, $count, $lines );
        }
    }
    $progress->withdraw if defined $progress;
    close $tempfh;
    if ( -e $filename ) {
        chmod 0777, $filename;
        unlink $filename;
    }
    if ( rename( $tempfilename, $filename ) ) {
        #$w->ResetUndo; #serves no purpose to reset undo
        $w->FileName($filename);
        return 1;
    } else {
        my $msg = "Cannot save $filename:$!. Text is in the temporary 
+file $tempfilename.";
        $w->messageBox(
            -icon    => 'warning',
            -title   => 'Warning',
            -type    => 'OK',
            -message => $msg.(OS_Win?" (Are you using Windows Explorer
+ Preview?)":""),
        );
        $w->BackTrace($msg);
        return 0;
    }
}
