[-L|-M [-X check]...] input_1 [input_2] 723 724where input_1 and input_2 may specify proto lists, proto areas, 725or manifest directories. For proto lists, use one or more 726 727 -l file 728 729arguments. For proto areas, use one or more 730 731 -p dir 732 733arguments. For manifest directories, use one or more 734 735 -m dir 736 737arguments. 738 739If -L or -M is specified, then only one input source is allowed, and 740it should be one or more manifest directories. These two options are 741mutually exclusive. 742 743The -L option is used to generate a proto list to stdout. 744 745The -M option is used to check for safe file and directory modes. 746By default, this causes all mode checks to be performed. Individual 747mode checks may be turned off using "-X check," where "check" comes 748from the following set of checks: 749 750 m check for group or other write permissions 751 w check for user write permissions on files and directories 752 not owned by root 753 s check for group/other read permission on executable files 754 that have setuid/setgid bit(s) 755 o check for files that could be safely owned by root 756""" % sys.argv[0] 757 758 759def usage(msg=None): 760 """Try to give the user useful information when they don't get the 761 command syntax right. 762 """ 763 if msg: 764 sys.stderr.write("%s: %s\n" % (sys.argv[0], msg)) 765 sys.stderr.write(USAGE) 766 sys.exit(2) 767 768 769def main(argv): 770 """Compares two out of three possible data sources: a proto list, a 771 set of proto areas, and a set of manifests. 772 """ 773 try: 774 opts, args = getopt.getopt(argv, 'a:e:Ll:Mm:p:vX:') 775 except getopt.GetoptError, exc: 776 usage(str(exc)) 777 778 if args: 779 usage() 780 781 arch = None 782 exceptionlists = [] 783 listonly = False 784 manifestdirs = [] 785 manifesttree = ManifestTree("manifests") 786 protodirs = [] 787 prototree = ProtoTree("proto area") 788 protolists = [] 789 protolist = ProtoTree("proto list") 790 modechecks = set() 791 togglemodechecks = set() 792 trees = [] 793 comparing = set() 794 verbose = False 795 796 for opt, arg in opts: 797 if opt == "-a": 798 if arch: 799 usage("may only specify one architecture") 800 else: 801 arch = arg 802 elif opt == "-e": 803 exceptionlists.append(arg) 804 elif opt == "-L": 805 listonly = True 806 elif opt == "-l": 807 comparing.add("protolist") 808 protolists.append(os.path.normpath(arg)) 809 elif opt == "-M": 810 modechecks.update(DEFAULTMODECHECKS) 811 elif opt == "-m": 812 comparing.add("manifests") 813 manifestdirs.append(os.path.normpath(arg)) 814 elif opt == "-p": 815 comparing.add("proto area") 816 protodirs.append(os.path.normpath(arg)) 817 elif opt == "-v": 818 verbose = True 819 elif opt == "-X": 820 togglemodechecks.add(arg) 821 822 if listonly or len(modechecks) > 0: 823 if len(comparing) != 1 or "manifests" not in comparing: 824 usage("-L and -M require one or more -m args, and no -l or -p") 825 if listonly and len(modechecks) > 0: 826 usage("-L and -M are mutually exclusive") 827 elif len(comparing) != 2: 828 usage("must specify exactly two of -l, -m, and -p") 829 830 if len(togglemodechecks) > 0 and len(modechecks) == 0: 831 usage("-X requires -M") 832 833 for s in togglemodechecks: 834 if s not in ALLMODECHECKS: 835 usage("unknown mode check %s" % s) 836 modechecks.symmetric_difference_update((s)) 837 838 if len(modechecks) == 0: 839 modechecks = None 840 841 if not arch: 842 usage("must specify architecture") 843 844 exceptions = ExceptionList(exceptionlists, arch) 845 originalexceptions = exceptions.copy() 846 847 if len(manifestdirs) > 0: 848 for mdir in manifestdirs: 849 manifesttree.adddir(mdir, arch, modechecks, exceptions) 850 if listonly: 851 manifesttree.resolvehardlinks() 852 for info in manifesttree.values(): 853 print "%s" % info.protostr() 854 sys.exit(0) 855 if modechecks is not None: 856 sys.exit(0) 857 trees.append(manifesttree) 858 859 if len(protodirs) > 0: 860 for pdir in protodirs: 861 prototree.adddir(pdir, exceptions) 862 trees.append(prototree) 863 864 if len(protolists) > 0: 865 for plist in protolists: 866 try: 867 protolist.addprotolist(plist, exceptions) 868 except IOError, exc: 869 sys.stderr.write("warning: %s\n" % str(exc)) 870 trees.append(protolist) 871 872 if verbose and exceptions: 873 print "Entries present in exception list but missing from proto area:" 874 for exc in sorted(exceptions): 875 print "\t%s" % exc 876 print "" 877 878 usedexceptions = originalexceptions.difference(exceptions) 879 harmfulexceptions = usedexceptions.intersection(manifesttree) 880 if harmfulexceptions: 881 print "Entries present in exception list but also in manifests:" 882 for exc in sorted(harmfulexceptions): 883 print "\t%s" % exc 884 del manifesttree[exc] 885 print "" 886 887 trees[0].compare(trees[1]) 888 889if __name__ == '__main__': 890 try: 891 main(sys.argv[1:]) 892 except KeyboardInterrupt: 893 sys.exit(1) 894 except IOError: 895 sys.exit(1) 896
