I tested in two different environments in java 8 + duckdb 0.10.0 + windows and in java 8 + duckdb 0.10.0 + linux on kubernetes (on windows it doesn't seem to have the memory leak problem, but on kubernetes it does). I also tried using jelastic with -javaagent:/usr/apache-tomcat/...
暂不谈论手机内存泄露问题的定位, 只介绍一个实用的linux小命令:mtrace(memory trace), 它能够用来协助定位内存泄露。 搞开发的, 应该或多或少地听说过mtrace. 以下, 我们来看看程序: #include <stdio.h> int main() { setenv("MALLOC_TRACE", "taoge.log", "1"); mtrace(); int *p = (int *)mall...
使用Linux的PRELOAD重载malloc/free的函数实现,然后可以记录下来所有的malloc/free操作。 定义PRELOAD库的源文件 $ cat mymalloc.c#define_GNU_SOURCE#include<stdio.h>#include<stdlib.h>#include<unistd.h>#include#include<sys/types.h>#include<sys/stat.h>#include<fcntl.h>#include<dlfcn.h>#include<string....
我将使用Linux作为目标示例,然后总结其他操作系统。 Linux 上有许多用于内存分析的跟踪器。我将在这里使用 perf 和 bcc/eBPF,这是标准的 Linux 跟踪器。perf 和 eBPF 都是 Linux 内核源的一部分。perf 适用于较旧的 Linux 系统,而 eBPF 至少需要 Linux 4.8 来执行堆栈跟踪。eBPF 可以更轻松地执行内核摘要,使其...
利用linux的mtrace命令定位内存泄露(Memory Leak),一谈到内存泄露,多数程序员都闻之色变。没错,内存泄露很容易引入,但很难定位。以你我的手机为例(假设不经常关机),如果每天泄露一些内存,那么开始的一个星期,你会发现手机好好的,当内存泄露积累到一定程度,那就是
