stack-overflow

I made my own implementation of ClientDetailsService: @Service public class JpaClientDetailsService implements ClientDetailsService { @Autowired private ClientRepository clientRepositoy; @Override public ClientDetails loadClientByClientId(String clientId) throws ClientRegistrationException { ClientDetails client = clientRepositoy.findOne(clientId); if (client == null) { throw new ClientRegistrationException(String.format("Client with id %s not found", clientId)); } return client; } } ClientRepository is a standard JpaRepository. I configured an AuthorizationServerConfigurerAdapter like this:

I been working on Native Android App where i face some bug on purticularly Android 2.3.3 versions and below Android 3.0 version . I am not getting where exactly am falling in my code because in Logcat Every Line of code compiled but at the end am getting very strange error describe log below: java.lang.StackOverflowError at java.util.concurrent.locks.ReentrantLock$NonfairSync.tryAcquire(ReentrantLock.java:189) at java.util.concurrent.locks.AbstractQueuedSynchronizer.acquire(AbstractQueuedSynchronizer.java:1171) at java.util.concurrent.locks.ReentrantLock$NonfairSync.lock(ReentrantLock.java:185

I was playing around with the State monad, and I don't know what's causing the stack overflow in this simple piece of code. import Control.Monad.State.Lazy tick :: State Int Int tick = do n <- get put $! (n+1) return n million :: Int million = snd $ runState (mapM_ (const tick) [1..1000000]) 0 main = print million Note I would just like to know what's causing the problem in this piece of code, the task itself is not important per se. The problem is that Control.Monad.State.Lazy's (>>=) is so lazy that even the ($!) doesn't help you. Try Control.Monad.State.Strict, that should reach the ($!).

As reference, I'm using the following code: #include <stdio.h> #include <string.h> int main (void) { char buf[100]; // ------> How do I find the address in gdb? printf ("Buffer is at memory location: %08x\n", &buf); strcpy (buf, "some random text"); printf ("Text is [%s]\n", buf); return 0; } How can I get gdb to show me the address of the buf variable? Nikolai Fetissov (gdb) p &a if you need the address of variable a . A variable might be cached in a register though, in which case GDB would tell you address requested for identifier "a" which is in register $xxx . Sidenote: do not use gets ,

I'm trying to figure out how to accomplish the equivalent of: select * from Users u inner join Comments c on c.UserId = u.Id where Id = 1569 (table aliases for better sql readability) ...on the StackOverflow OData endpoint. How would this url be constructed? I'm looking at the documentation for Expand at OData.org and I would have thought it'd look something like: https://odata.sqlazurelabs.com/OData.svc/v0.1/rp1uiewita/StackOverflow/Users?$Expand=Comments&$filter=UserId eq 1569 but isn't right. In Linq, it would be this (I think), but Join isn't supported: Users.Where(u=>u.Id==1569).Join

When observing a StackOverflowError how to retrieve the full call stack? Consider this simple example: public class Overflow { public Overflow() { new Overflow(); } public static void a() { new Overflow(); } public static void main(String[] argv) { a(); } } Now the error reported is: Exception in thread "main" java.lang.StackOverflowError at Overflow.<init>(Overflow.java:11) [last line repeated many times] But I can't see the main and a method in the stack trace. My guess is this is because of overflow, the newest entry on the stack replaces the oldest one (?). Now, how to get the a and main

I read in this presentation http://golang.org/doc/ExpressivenessOfGo.pdf page 42: Safe - no stack overflows How is this possible? and/or how does Go works to avoid this? It's a feature called "segmented stacks": every goroutine has its own stack, allocated on the heap . In the simplest case, programming language implementations use a single stack per process/address space, commonly managed with special processor instructions called push and pop (or something like that) and implemented as a dynamic array of stack frames starting at a fixed address (commonly, the top of virtual memory). That is

I get a StackOverflowException when I run the following code: private void MyButton_Click(object sender, EventArgs e) { MyButton_Click_Aux(); } private static volatile int reportCount; private static void MyButton_Click_Aux() { try { /*remove because stack overflows without*/ } finally { var myLogData = new ArrayList(); myLogData.Add(reportCount); myLogData.Add("method MyButtonClickAux"); Log(myLogData); } } private static void Log(object logData) { // my log code is not matter } What could be causing the StackOverflowException ? I know how to stop it from happening I just don't know why it
