After the file test -you may put C<|| die> to make it a fatal error if the file test fails. -The default is C<|| warn>. The file test may optionally have a "!' prepended -to test for the opposite condition. If you do a cd and then list some -relative filenames, you may want to indent them slightly for readability. -If you supply your own die() or warn() message, you can use $file to -interpolate the filename. - -Filetests may be bunched: "-rwx" tests for all of C<-r>, C<-w>, and C<-x>. -Only the first failed test of the bunch will produce a warning. - -The routine returns the number of warnings issued. - -=head1 AUTHOR - -File::CheckTree was derived from lib/validate.pl which was -written by Larry Wall. -Revised by Paul Grassie <F<grassie@perl.com>> in 2002. - -=head1 HISTORY - -File::CheckTree used to not display fatal error messages. -It used to count only those warnings produced by a generic C<|| warn> -(and not those in which the user supplied the message). In addition, -the validate() routine would leave the user program in whatever -directory was last entered through the use of "cd" directives. -These bugs were fixed during the development of perl 5.8. -The first fixed version of File::CheckTree was 4.2. - -=cut - -my $Warnings; - -sub validate { - my ($starting_dir, $file, $test, $cwd, $oldwarnings); - - $starting_dir = cwd; - - $cwd = ""; - $Warnings = 0; - - foreach my $check (split /\n/, $_[0]) { - my ($testlist, @testlist); - - # skip blanks/comments - next if $check =~ /^\s*#/ || $check =~ /^\s*$/; - - # Todo: - # should probably check for invalid directives and die - # but earlier versions of File::CheckTree did not do this either - - # split a line like "/foo -r || die" - # so that $file is "/foo", $test is "-r || die" - # (making special allowance for quoted filenames). - if ($check =~ m/^\s*"([^"]+)"\s+(.*?)\s*$/ or - $check =~ m/^\s*'([^']+)'\s+(.*?)\s*$/ or - $check =~ m/^\s*(\S+?)\s+(\S.*?)\s*$/) - { - ($file, $test) = ($1,$2); - } - else { - die "Malformed line: '$check'"; - }; - - # change a $test like "!-ug || die" to "!-Z || die", - # capturing the bundled tests (e.g. "ug") in $2 - if ($test =~ s/ ^ (!?-) (\w{2,}) \b /$1Z/x) { - $testlist = $2; - # split bundled tests, e.g. "ug" to 'u', 'g' - @testlist = split(//, $testlist); - } - else { - # put in placeholder Z for stand-alone test - @testlist = ('Z'); - } - - # will compare these two later to stop on 1st warning w/in a bundle - $oldwarnings = $Warnings; - - foreach my $one (@testlist) { - # examples of $test: "!-Z || die" or "-w || warn" - my $this = $test; - - # expand relative $file to full pathname if preceded by cd directive - $file = File::Spec->catfile($cwd, $file) - if $cwd && !File::Spec->file_name_is_absolute($file); - - # put filename in after the test operator - $this =~ s/(-\w\b)/$1 "\$file"/g; - - # change the "-Z" representing a bundle with the $one test - $this =~ s/-Z/-$one/; - - # if it's a "cd" directive... - if ($this =~ /^cd\b/) { - # add "|| die ..." - $this .= ' || die "cannot cd to $file\n"'; - # expand "cd" directive with directory name - $this =~ s/\bcd\b/chdir(\$cwd = '$file')/; - } - else { - # add "|| warn" as a default disposition - $this .= ' || warn' unless $this =~ /\|\|/; - - # change a generic ".. || die" or ".. || warn" - # to call valmess instead of die/warn directly - # valmess will look up the error message from %Val_Message - $this =~ s/ ^ ( (\S+) \s+ \S+ ) \s* \|\| \s* (die|warn) \s* $ - /$1 || valmess('$3', '$2', \$file)/x; - } - - { - # count warnings, either from valmess or '-r || warn "my msg"' - # also, call any pre-existing signal handler for __WARN__ - my $orig_sigwarn = $SIG{__WARN__}; - local $SIG{__WARN__} = sub { - ++$Warnings; - if ( $orig_sigwarn ) { - $orig_sigwarn->(@_); - } - else { - warn "@_"; - } - }; - - # do the test - eval $this; - - # re-raise an exception caused by a "... || die" test - if (my $err = $@) { - # in case of any cd directives, return from whence we came - if ($starting_dir ne cwd) { - chdir($starting_dir) || die "$starting_dir: $!"; - } - die $err; - } - } - - # stop on 1st warning within a bundle of tests - last if $Warnings > $oldwarnings; - } - } - - # in case of any cd directives, return from whence we came - if ($starting_dir ne cwd) { - chdir($starting_dir) || die "chdir $starting_dir: $!"; - } - - return $Warnings; -} - -my %Val_Message = ( - 'r' => "is not readable by uid $>.", - 'w' => "is not writable by uid $>.", - 'x' => "is not executable by uid $>.", - 'o' => "is not owned by uid $>.", - 'R' => "is not readable by you.", - 'W' => "is not writable by you.", - 'X' => "is not executable by you.", - 'O' => "is not owned by you.", - 'e' => "does not exist.", - 'z' => "does not have zero size.", - 's' => "does not have non-zero size.", - 'f' => "is not a plain file.", - 'd' => "is not a directory.", - 'l' => "is not a symbolic link.", - 'p' => "is not a named pipe (FIFO).", - 'S' => "is not a socket.", - 'b' => "is not a block special file.", - 'c' => "is not a character special file.", - 'u' => "does not have the setuid bit set.", - 'g' => "does not have the setgid bit set.", - 'k' => "does not have the sticky bit set.", - 'T' => "is not a text file.", - 'B' => "is not a binary file." -); - -sub valmess { - my ($disposition, $test, $file) = @_; - my $ferror; - - if ($test =~ / ^ (!?) -(\w) \s* $ /x) { - my ($neg, $ftype) = ($1, $2); - - $ferror = "$file $Val_Message{$ftype}"; - - if ($neg eq '!') { - $ferror =~ s/ is not / should not be / || - $ferror =~ s/ does not / should not / || - $ferror =~ s/ not / /; - } - } - else { - $ferror = "Can't do $test $file.\n"; - } - - die "$ferror\n" if $disposition eq 'die'; - warn "$ferror\n"; -} - -1; |
