abort

Since Xcode 7 and Swift 2.0, in my current project, I get the error above : Assertion failed: (Conformance.size() == Archetype->getConformsTo().size() && "substitution conformances don't match archetype"), function Substitution, file /Library/Caches/com.apple.xbs/Sources/swiftlang/swiftlang-700.0.38.1/src/swift/lib/AST/Substitution.cpp, line 64. 0 swift 0x0000000111d84e0b llvm::sys::PrintStackTrace(__sFILE*) + 43 1 swift 0x0000000111d8554b SignalHandler(int) + 379 2 libsystem_platform.dylib 0x00007fff8bcc7f1a _sigtramp + 26 3 libsystem_platform.dylib 000000000000000000 _sigtramp + 1949532416 4

I had a discussion the other day: https://stackoverflow.com/a/42156860/937125 where I didn't quite understand why an Abort was better than calling Exit in that situation. I tend not to use it in my code flow. I consider it a bad practice and bad for code flow. but @David's statement in the comments made me wonder if maybe I was missing something: Without a silent exception, how would you abort an operation when deep down the call stack. For instance how would you abort a file copy operation with a 10 deep call stack? Isn't that exactly what exceptions are designed for? Sure you can code it

I'm trying to gracefully exit my program after if Rdinput returns an error. #include <mpi.h> #include <stdio.h> #include <stdlib.h> #define MASTER 0 #define Abort(x) MPI_Abort(MPI_COMM_WORLD, x) #define Bcast(send_data, count, type) MPI_Bcast(send_data, count, type, MASTER, GROUP) //root --> MASTER #define Finalize() MPI_Finalize() int main(int argc, char **argv){ //Code if( rank == MASTER ) { time (&start); printf("Initialized at %s\n", ctime (&start) ); //Read file error = RdInput(); } Bcast(&error, 1, INT); Wait(); if( error = 1 ) MPI_Abort(1); //Code Finalize(); } Program output: mpirun

I'm trying to enter a number,n and get the least super lucky number that is more than or equal to n. Super lucky: it's decimal representation contains equal amount of digits 4 and 7. For example, numbers 47, 7744, 474477 are super lucky and 4, 744, 467 are not. Here's my code #include<iostream> #include<string> using namespace std; void superLucky(int n,string s, int count4, int count7) { if (s.size() > 10) return; if (( stoi(s) >= n ) && (count4 == count7) && (count4+count7)!=0) { cout << s << endl; return; } superLucky(n, s + '4', count4+1, count7); superLucky(n, s + '7',count4,count7+1); }

1、Abort当前线程，后续程序不会执行 class Program { public static Thread thread1; static void Main(string[] args) { thread1 = new Thread(Method1); thread1.Start(); Console.ReadKey(); } public static void Method1() { try { for (int i = 0; i < 10; i++) { Console.WriteLine("Mthod1: " + i.ToString()); Thread.Sleep(1000); if (i == 3) { Thread.CurrentThread.Abort(); // 抛出的ThreadAbortException异常 } Console.WriteLine("Mthod1: " + i.ToString() + " End"); } } catch (SocketException ex) { Console.WriteLine("Method1 SocketException: " + ex.ToString()); } catch (ThreadAbortException ex) { //
