C++/Windows: How to report an out-of-memory exception (bad_alloc)?

由 时间秒杀一切 提交于 2019-12-23 07:56:27
问题 I'm currently working on an exception-based error reporting system for Windows MSVC++ (9.0) apps (i.e. exception structures & types / inheritance, call stack, error reporting & logging and so on). My question now is: how to correctly report & log an out-of-memory error? When this error occurs, e.g. as an bad_alloc thrown by the new op, there may be many "features" unavailable, mostly concerning further memory allocation. Normally, I'd pass the exception to the application if it has been

问题 I have a nice tidy way of capturing unhandled exceptions which I display to my users and (optionally) get emailed to myself. They generally look something like this: Uncaught exception encountered in MyApp (Version 1.1.0)! Exception: Object reference not set to an instance of an object. Exception type: System.NullReferenceException Source: MyApp Stack trace: at SomeLibrary.DoMoreStuff() in c:\projects\myapp\somelibrary.h:line 509 at SomeAlgothim.DoStuff() in c:\projects\myapp\somealgorithm.h

How to change the way PHP writes errors in the error log file?

由 允我心安 提交于 2019-12-22 09:18:30
问题 I have been working on my website for over a year now, and I am very anxious to finally put it out there for people to use. It has gotten quite large however - I almost want to say out of my control - and on top of that I am really just an self taught amateur programmer. So I want to be sure, that any errors that php produces are logged in a file, so I can than access this file and track errors down. Currently my settings are the following: <?php error_reporting(E_ALL); ini_set('display

Php not reporting any errors on IIS7

由 空扰寡人 提交于 2019-12-21 18:57:10
问题 I am developing a PHP application using our XAMPP setup as a test server. Once the app is ready to deploy, I have to upload it to the client's server, The problem is the client's server is running IIS 7, and every time there is a PHP error it just displays a blank page... Now, my app has error_reporting(E_ALL) already set, and I do not have access to the php.ini file (don't ask why!)... and I have tried every combination of parameters for error_reporting() found here: http://www.php.net

Does PHP error_reporting(0) affect error logging, or just display?

由 走远了吗. 提交于 2019-12-18 15:01:12
问题 Does error_reporting(0); have any effect on error logging (to file), or does it just suppress on-screen error display? Thanks. 回答1: Yes, it affects both. The error_reporting level defines what levels of errors gets triggered . Whether you log or display those errors are determined by the other settings. To summarize: error_reporting: What levels of errors get triggered. display_errors: Whether to show triggered errors in script output. log_errors: Whether to write triggered errors to a log.

PHP 5.4: disable warning “Creating default object from empty value”

由 感情迁移 提交于 2019-12-17 19:20:02
问题 I want to migrate code from PHP 5.2 to 5.4. This worked fine so far except that all the code I use makes extensive use of just using an object with a member without any initialisation, like: $MyObject->MyMember = "Hello"; which results in the warning: "Creating default object from empty value" I know that the solution would be to use: $MyObject = new stdClass(); $MyObject->MyMember = "Hello"; but it would be A LOT OF WORK to change this in all my code, because I use this many times in
