javascript - Chrome-only cross-domain scripting errs in Facebook iFrame App upon FB.Login(..) -

-

in google chrome (i'm on 9.0.597.98) facebook iframe app using graph api/javascript sdk tends throw following 2 javascript errors (see below) based on cross-domain scripting, on 1 page of app.

it goes endless retry loop on second message. after leaving overnight, reported half million retries morning!

the fb call being used login:

fb.login(function(response) {   if (response.session) {     // user logged in   } else {     // user cancelled login   } });

in firefox , ie9 not these errors. it's specific chrome (maybe webkit). what's odd have second page in app uses fb.login , works in chrome in addition other browsers. read somewhere safari has more stringent requirements on cross domain scripting - , chrome share same code base.

domains, protocols , ports must match (error message) believe satisfied because have page works fb.login call the other difference see between these 2 messages postmessage query argument has different value each (bolded in messages). there 1 iframe constitutes facebook app wonder why 2 different values might used 1 after other. don't mean lead answers focus on item, did want point out.

suggestions welcome might try resolve errors.

i ran issue getloginstatus() not being called in chrome. tried calling on page load , after user-initiated action no success.

it turned out not cross-domain issue. call being blocked un-passwordise extension in chrome. disabled extension, worked perfectly, on page load.

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
