html - Odd javascript XSS error -

-

i'm designing simple way communicate between iframes, , getting odd xss error, though both urls have save domain.

unsafe javascript attempt access frame url file:///home/bryre/shareddata/programs/javascript/pong/htdocs/connectionwindow.html frame url file:///home/bryre/shareddata/programs/javascript/pong/htdocs/connectiontest.html. domains, protocols , ports must match.

do need have them on server work? here code:

connectiontest.html

<html> <head>     <title>connectiontest</title>     <script src='connection.js'></script> </head> <body>     <script>         var windowtoconnectto = document.createelement('iframe')         windowtoconnectto.src = 'connectionwindow.html'         document.body.appendchild(windowtoconnectto)          var connection = new connection({});         connection.connect(windowtoconnectto, 10);     </script> </body>

connectionwindow.html

<html> <head>     <title>connectiontest</title>     <script src='connection.js'></script> </head> <body>     <script>         var connection = new connection({});     </script> </body>

connection.js

function connection(commands){ this.indiv = document.createelement('div') this.indiv.id = 'in' this.indiv.style.disply = 'none' document.body.appendchild(this.indiv)  this.commands = commands }  connection.prototype = { attemptconnect: function(to){     to.document = (to.contentwindow || to.contentdocument)     if(to.document.document)         to.document = to.document.document     this.to = to.document.getelementbyid('in') //error happens here     if(this.to == null)         return false     return true }, connect: function(to, retryrate){     cthis =     var interval = setinterval(function(){         if(cthis.attemptconnect(to))             clearinterval(interval)     }, retryrate) } }

they don't have domain, local files. use http server access them.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

-
what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

fortran - Function return type mismatch -

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
