[linux] 内存测试 gperftools

内存测试构建：

工具：gperftools/heap_checker

https://gperftools.github.io/gperftools/heap_checker.html
安装google-perftools：
 
apt-get install libunwind-dev
apt-get install google-perftools

安装google-perftools：

git clone https://github.com/libunwind/libunwind.git
cd libunwind
sh ./autogen.sh 
./configure 
make
sudo make install

git clone https://github.com/gperftools/gperftools.git
sh autogen.sh 
./configure 
make
sudo make install

可视化：

sudo apt install kcachegrind

方式1，编译时指定

g++ -g -o -ltcmalloc xxx

方式2，启动时加载

You can run the heap checker on applications you didn't compile yourself, by using LD_PRELOAD:
  $ LD_PRELOAD="/usr/lib/libtcmalloc.so" HEAPCHECK=normal 
We don't necessarily recommend this mode of usage.

运行

export LD_PRELOAD="/usr/local/lib/libtcmalloc.so" 
export PPROF_PATH="/usr/local/bin/pprof" 
export HEAPCHECK="normal" 
./main

可视化输出

pprof ./hello "/tmp/hello.1536222._main_-end.heap" --inuse_objects --lines --heapcheck  --edgefraction=1e-10 --nodefraction=1e-10 --svg >> analize.svg
