So, try to fool it. ## CVS calls geteuid() to determine rootness (so does perl's $>). ## If root, CVS calls getlogin() first, then checks the LOGNAME and USER ## environment vars. ## ## What this means is: if the user is actually logged in on a physical ## terminal as 'root', getlogin() will return "root" to cvs and we can't ## fool CVS. ## ## However, if they've used "su", a very common occurence, then getlogin() ## will return failure (NULL in C, undef in Perl) and we can spoof CVS ## using $ENV{LOGNAME}. if ( ! $> && $^O !~ /Win32/ ) { my $login = getlogin ; if ( ( ! defined $login || ! getpwnam $login ) && ( ! exists $ENV{LOGNAME} || ! getpwnam $ENV{LOGNAME} ) ) { for ( qw( nobody guest ) ) { my $uid = getpwnam $_ ; next unless defined $uid ; ( $ENV{LOGNAME}, $> ) = ( $_, $uid ) ; last ; } ## Must set uid, too, to keep perl (and thus vcp) from bombing ## out when running setuid and given a -I option. This happens ## a lot in the test suite, since the tests often call vcp ## using "perl", "-Iblib/lib", "bin/vcp", ... to recreate the ## appropriate operating environment for Perl. If this becomes ## a problem, perhaps we can hack in a "run as user" option to ## VCP::Utils::cvs so that only the cvs subcommands are run ## setuid, or perhaps we can avoid passing "-I" to the perls. $< = $> ; warn "# Setting real & eff. uids=", $>, "(", $ENV{LOGNAME}, qq{) to quell "cvs: cannot commit files as 'root'"\n} ; } } run [ qw( cvs init ) ]; chdir $options->{work} or die "$!: $options->{work}" ; mkdir $module, 0770 or die "$!: $module" ; chdir $module or die "$!: $module" ; run [ qw( cvs import -m ), "$module import", $module, "${module}_vendor", "${module}_release" ]; chdir $cwd or die "$!: $cwd" ; delete $ENV{CVSROOT} ; # chdir ".." or die "$! .." ; # # system qw( cvs checkout CVSROOT/modules ) and die "cvs checkout failed" ; # # open MODULES, ">>CVSROOT/modules" or die "$!: CVSROOT/modules" ; # print MODULES "\n$module $module/\n" or die "$!: CVSROOT/modules" ; # close MODULES or die "$!: CVSROOT/modules" ; # # system qw( cvs commit -m foo CVSROOT/modules ) # and die "cvs commit failed" ; return $options ; } =back =head1 VSS mgmt functions =over =item vss_borken fails unless $ENV{SSUSER} is defined and the command C runs and returns what looks like a username. May lock up if the ss.exe command prompts for a password. This is because I can't figure out a reliable way to detect if the "ss" command runs well without risking a lock up, since it has a habit of prompting for a password that I can't break it of without initalizing a custom Source Safe repository. =cut sub vss_borken { return "SSUSER not in the environment" unless defined $ENV{SSUSER}; my $user = `ss Whoami` ; return "ss command not found" if empty $user; return "ss command did not return just a username" unless $user =~ /\A\S+$/m; return "" ; } =back =head1 COPYRIGHT Copyright 2000, Perforce Software, Inc.
