问题 I have a PHP file that generates xls files using the module found at http://pear.php.net/package/Spreadsheet_Excel_Writer/ I can create the sample document just fine and when I open it, it looks fine. My next step it to turn it into a downloadable link. To do that, I did this: $mimeType = "application/vnd.ms-excel"; $file_name = "test.xls"; $file_path = "/tmp/".$file_name; header("Pragma: public"); header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0");

问题 A unforeseen and unanticipated amount of garbage collection activity is shown in the 'Process Memory' graph when I run my application which makes me want to know where in the program is the garbage generated as I don't feel that I have any memory leaks in the program. Can someone please tell me if there is a way to view the parts (or lines) of my code where garbage is generated? Thanks in advance. 回答1: Pretty much any memory profiler will show this info. Just look for a list of "Dead objects"

问题 Hi guys in my previous question, I was able to get the data of a struct to be loaded on a file, but now the issue is I'm getting garbage value while retrieving it. File Contents: settings.bin 110#NormalCompression Level210#NormalCompression Level310#NormalCompression Level410#NormalCompression Level510#NormalCompression Level Code #include<cstdlib> #include<iostream> #include<string> #include<iomanip> #include<fstream.h> using namespace std; const char* ErrorLogFilePath = "resources\\error

问题 Is it possible to run the garbage collection in a separate thread? So that it dosent block the main Thread of the process? 回答1: Background GC happens on a separate thread already - that's why it's "background" - but there is part of the GC lifecycle that must block all threads in the process (not just the main thread) to complete - it's an unavoidable necessity that MS has worked to minimize - you can facilitate it in your code by being as smart with your own object lifecycles, using look

问题 I plan to use an object which is called by my main method to exit the entire program. The object has a method which just runs a System.exit(0). My question is, is this a safe thing to do? If I run System.exit(0) from another object, will garbage collection still clean out the entire program from memory, or will I have issues cleaning the calling class from memory? My thoughts are that either since the JVM will be terminated, the calling class will be garbage-collected, or that I might have
