我怎么告诉的valgrind到MEMCHECK派生进程？ [英] How do I tell valgrind to memcheck forked processes?

问题描述

我有一个过程 X 我要检查与的valgrind 泄漏。问题是， X 是是和是又是以Z 运行。我不能运行 X 独立的，因为是和以Z 设置为环境X ，如环境变量，命令行开关，由 X所需的文件等

1. 有什么办法，我可以告诉的valgrind 在以Z 运行，但按照其发现的任何叉子和报告他们呢？


2. 有什么办法，我可以告诉的valgrind 遵循任何叉子，但只在名为进程报告 X ？


3. 有什么办法，我可以告诉的valgrind 附加到已经运行的过程中，我可以使用gdb的方式做？

我不知道这事，但我下Suse64 linux和的valgrind-2.4.0。

运行

谢谢！

解决方案

微量的孩子= YES 选项 -
1. Valgrind的给出的时，如下派生进程。


2. 您应该能够通过使用合适的过滤器来实现这一目标。


3. 没有。 Valgrind的挂接到模块加载code。使用LD_ preLOAD，所以连接到正在运行的进程是不可能的。

I have a process x that I want to check for leaks with valgrind. The problem is that x is run by y, and y in turn is run by z. I can't run x standalone because y and z setup the environment for x, such as environment variables, command line switches, files needed by x etc.

1. Is there any way I can tell valgrind to run on z but to follow any forks it finds and report them too?
2. Is there any way I can tell valgrind to follow any forks but only report on the process named x?
3. Is there any way I can tell valgrind to attach to already-running process, the way I can do with gdb?

I don't know if this matters, but I'm running under Suse64 linux and valgrind-2.4.0.

Thanks!

解决方案

1. Valgrind follows forked processes when given the --trace-children=yes option.
2. You should be able to achieve this by using suitable filters.
3. No. Valgrind hooks into the module loading code using LD_PRELOAD, so attaching to a running process is not possible.
