abort

问题 Some C++ libraries call abort() function in the case of error (for example, SDL). No helpful debug information is provided in this case. It is not possible to catch abort call and to write some diagnostics log output. I would like to override this behaviour globally without rewriting/rebuilding these libraries. I would like to throw exception and handle it. Is it possible? 回答1: Note that abort raises the SIGABRT signal, as if it called raise(SIGABRT) . You can install a signal handler that

问题 I've just finished reading "C# 4.0 in a Nutshell" (O'Reilly) and I think it's a great book for a programmer willing to switch to C#, but it left me wondering. My problem is the definition of using statement. According to the book (p. 138), using (StreamReader reader = File.OpenText("file.txt")) { ... } is precisely equivalent to: StreamReader reader = File.OpenText("file.txt"); try { ... } finally { if (reader != null) ((IDisposable)reader).Dispose(); } Suppose, however, that this is true and

问题 I am working on an application in which i have to stop listening to a request if certain time is passed like if there is no response from a request in 60 secs then i have to abort that request and also there are multiple requests are going at a time. I don't know know how to keep track of each request with abort time(60 secs) . I mean how would i know which request is to abort. I want to implement this functionality in my AngularJS interceptor. I have tried many blogs and post that claims to

问题 I am working on ARM 7 board and facing data handler related issues i.e. many times board got stuck at 0x10 . I checked CPSR register and found mode is 0x17(Abort mode). How to handle this Data Abort exception in ARM 7 ? I tried to configure in exception vector but it failed. Also the R14(Linked Register) is different at every time. Disassembly Next label is a Thumb label FIQ_MODE: USER_MODE: --> 00000010 E59FF018 LDR PC, [PC, #+24] ;D ABT [0x30] = USR_MODE (0x10) Using IAR. Data Abort

问题 I've found several answers including this one and also this one. But for some reason this.Response.IsClientConnected still goes as true . Here is my Client: <div class="ajax-loader-gif-close" id="cancelBusy">Close</div> @using (Html.BeginForm("List", "Visit", FormMethod.Post, new { @id = "formFilter" })) { //Some models some TextBoxFor etc. } <script type="text/javascript" language="javascript"> var ajaxCallObject = null; $(document).ready(function () { $('form').submit(function () {

问题 I want to kill my c++ program and terminate immediately without activating destructors of any kind, especially static and global variables, but I want to exit with status 0 - abort() will not work for me. Does anyone have a solution? Thanks 回答1: Maybe _exit(0); is what you're looking for? Here is the man page to read up about it. 回答2: From C++11 n3290 - § 18.5: [[noreturn]] void _Exit(int status) noexcept; The program is terminated without executing destructors for objects of automatic,

问题 We can reproduce this problem with very simple example by having more than one abort call in our source code. In the below example code we have total of four abort calls with in different conditions but when we compile with optimization flag(-O3) we can see debug info for only one abort call . so where ever crash happens with in these four abort calls gdb always gives the one which has debug info. #include <stdio.h> #include <stdlib.h> void level_aa(int a) { if (a == 0) abort(); if (a == 1)

问题 I know Nginx has nothing to do with the PHP-FPM process, but I would much prefer if the PHP-FPM process died if a user aborts so it doesn't continue doing needless things or wasting resources. For PHP-FPM/Nginx the trigger_error will happen regardless of user abort: <?php sleep(30); trigger_error('Still happened?'); ?> How can I do user aborts for PHP-FPM? (if possible) 回答1: This is not implemented by php-fpm, more info here. Setting ignore_user_abort(FALSE) only works when PHP sends data
