termination

问题 I'm getting a weird access violation at the end of my main whose cause I'm having some difficulties finding. When shutting down my application I get an access violation in the following: xdebug // TEMPLATE FUNCTION _DebugHeapDelete template<class _Ty> void __CLRCALL_OR_CDECL _DebugHeapDelete(_Ty *_Ptr) { // delete from the debug CRT heap even if operator delete exists if (_Ptr != 0) { // worth deleting _Ptr->~_Ty(); // delete as _NORMAL_BLOCK, not _CRT_BLOCK, since we might have // facets

问题 I’d like to define the following function using Program Fixpoint or Function in Coq: Require Import Coq.Lists.List. Import ListNotations. Require Import Coq.Program.Wf. Require Import Recdef. Inductive Tree := Node : nat -> list Tree -> Tree. Fixpoint height (t : Tree) : nat := match t with | Node x ts => S (fold_right Nat.max 0 (map height ts)) end. Program Fixpoint mapTree (f : nat -> nat) (t : Tree) {measure (height t)} : Tree := match t with Node x ts => Node (f x) (map (fun t => mapTree

问题 I'm writing an app in java allowing me to run other applications. To do that, I've used an Process class object, but when I do, the app awaits the process to end before exiting itself. Is there a way to run external application in Java, but don't wait for it to finish? public static void main(String[] args) { FastAppManager appManager = new FastAppManager(); appManager.startFastApp("notepad"); } public void startFastApp(String name) throws IOException { Process process = new ProcessBuilder

问题 I have a client application that once in while notifies about its progress a service. The method call to the service is marked with IsOneWay=true, because the notification doesn't need any return value and I don't want to delay. The client may notify about errors to the service, and afterward it terminates. The question is: does a oneway method call returns to the caller code after it sent the message? or it queues the message and later on it is sent by another thread? The two processes (the

问题 is there some way to run code on termination, no matter what kind termination (abnormal,normal,uncaught exception etc.)? I know its actually possible in Java, but is it even possible in C++? Im assuming a windows environment. 回答1: No -- if somebody invokes TerminateProcess , your process will be destroyed without further adieu, and (in particular) without any chance to run any more code in the process of shutting down. 回答2: For normal closing applciation I would suggest atexit() 回答3: One good

问题 Suppose we have a datatype of sorted lists, with proof-irrelevant sorting witnesses. We'll use Agda's experimental sized types feature, so that we can hopefully get some recursive functions over the datatype to pass Agda's termination checker. {-# OPTIONS --sized-types #-} open import Relation.Binary open import Relation.Binary.PropositionalEquality as P module ListMerge {𝒂 ℓ} (A : Set 𝒂) {_<_ : Rel A ℓ} (isStrictTotalOrder : IsStrictTotalOrder _≡_ _<_) where open import Level open import

问题 Today I recieved a notificiation e mail from Google: "This is a notification that your Google Play Publisher account has been terminated. REASON FOR TERMINATION: Prior violations of the Developer Program Policies and Developer Distribution Agreement by this or associated accounts as outlined in previous emails sent to the registered email address(es) of the Publisher account(s). Google Play Publisher suspensions are associated with developers, and may span multiple account registrations and

问题 I'm using sized types, and have a substitution function for typed terms which termination-checks if I give a definition directly, but not if I factor it via (monadic) join and fmap. {-# OPTIONS --sized-types #-} module Subst where open import Size To show the problem, it's enough to have unit and sums. I have data types of Trie and Term , and I use tries with a codomain of Term inside Term , as part of the elimination form for sums. data Type : Set where 𝟏 : Type _+_ : Type → Type → Type

问题 Function for determining if a set is a subset of another: Fixpoint subset (s1:bag) (s2:bag) : bool := match s1 with | nil => true | h :: t => match (beq_nat (count h s1) (count h s2)) with | true => subset (remove_all h t) (remove_all h s2) | false => false end end. For clarity beq_nat determines equality of two natural numbers count counts the number of times a given natural number occurs in a set remove_all removes each instance of a given natural number from a set CoqIDE "Cannot guess

问题 For some reason, my C# application is being terminated by svchost.exe and I'm trying to understand why. It was terminating the application silently until I turned on Silent Process Exit logging using Gflags.exe from the Windows Debugging Tools. It happens infrequently on machines that I can't running debugging tools on (customer pcs). The event doesn't really provide me with much info to go on. The termination code is 805306369=0x30000001, but I can't seem to find anything useful online that
