we have wcf service public class myservice { [operationcontract] public void opperationa() { } [operationcontract] public void opperationb() { } [operationcontract] public void opperationc() { } [operationcontract] public void opperationd() { } } we have client wcf service windows service invokes operations above operationa/b/c/d new proxies. with current implementation have there issues client invoking operations @ same time. instancecontextmode = percall , concurrencymode = single is there combination of instancecontextmode , concurrency can change service take 1 request @ time, mean if client proxy has called operationa , service processing request , if client proxy b tries call operationb (or other operation), should blocked until first request finished. thanks it should sufficient change instancecontextmode single. msdn documentation here : concurrencymode=single : service instance single-threaded , not accept reentrant calls.

is impression correct using regular new xyz() way of instantiating component xyz prevents spring processing @autowired fields inside xyz? second question: correct cannot use dependency injection in xyz , @ same time use final fields in xyz because of that? example: @component public class xyz { @autowired private somedep dep; private final int value; public xyz(int value) { this.value = value; } } how make working? so, well, accepting there no nicer way, let's way: @component public class xyz { @autowired private somedep dep; private final int value; // factory instantiation xyz() { value=0; } private xyz(somedep dep, int value) { this.dep = dep; this.value = value; } public xyz getinstance(int value) { return new xyz(dep, value); } } ??? ugly. , gets uglier when want move dependency declaration parent class....... ??? thought di nice. think have reconsider th

i'm reading string file(which can modify) , don't know type of coded string is. there function like getcodec = mystring.getcodec() which return like getcodec = 'utf-8' or getcodec = 'ascii' ? no, there no such function, because files not record codec used write text contained. if there more context (like more specific format such html or xml) can determine codec because standard specifies default or allows annotating data codec, otherwise reduced guessing based on contents (which tools chardet do). for file can modify, have no hope document codec should used.

i looking @ setting git repositories coming background in svn. here want: product repositories - these capture stand alone individual products (an application, library example) application a application b library c . . . project repositories - these capture aggregations of products form solution particular customer. project x repository project y repository project z repository . . . each project built of different combinations of products. example, project x built of application a, application b, , project specific code. project y build of application b, application c, , application d project specific code , settings. idea. in svn, project repositories use svn-externals include version of products. can accomplish repository concept detailed above or should thinking of different technique given power of git? consider using git submodules. details can found in submodules chapter of free online git book . quoting book: submodules allow keep

editor's note: code example version of rust prior 1.0 , not syntactically valid rust 1.0 code. updated versions of code produce different errors, answers still contain valuable information. i tried , without box , , without lifetimes: trait traittoimpl { fn do_something(self, val: i32); } struct cont { value: i32, } impl traittoimpl cont { fn do_something(self, val: i32) { println!("{}", val); } } struct storetrait<'a> { field: box<traittoimpl + 'a>, } fn main() { let cont = box::new(cont { value: 12 }) box<traittoimpl>; let = storetrait { field: cont }; a.field.do_something(123); } all error: error: cannot convert trait object because trait `traittoimpl` not object-safe the problem is, error message says, trait traittoimpl not object safe. is, not safe use particular trait through reference (i.e. &traittoimpl or box<traittoimpl> . specifically, do_something met

authorizeattribute requires override onauthorization method , iauthorizationfilter requires implement onauthorization method. seems same thing me, there other differences? why 1 used on other? edit: clarify, i'm trying understand difference between following 2 pieces of code. public class passwordexpirationcheckattribute : authorizeattribute { private int _maxpasswordageindays; public passwordexpirationcheckattribute(int maxpasswordageindays) { _maxpasswordageindays = maxpasswordageindays; } public override void onauthorization(authorizationcontext filtercontext) { if (!filtercontext.actiondescriptor.getcustomattributes(typeof(bypasspasswordexpirationcheckattribute), true).any()) { iprincipal userprincipal = filtercontext.requestcontext.httpcontext.user; if (userprincipal != null && userprincipal.identity.isauthenticated) { var userstore = new applicationuserstore
