Yangfisher1 opened a new issue, #3065:
URL: https://github.com/apache/brpc/issues/3065
为了breakdown性能引入了bvar IntRecorder
bvar::IntRecorder g_latency_recorder("xxxx");
在向这个recorder写入数据的时候发生segfault,
g_latency_recorder << xxx;
通过gdb bt检查发现是IntRecorder的_combiner成员为空,
检查代码后发现只有这样创建IntRecorder时才会初始化_combiner, 否则是不会初始化的
bvar::IntRecorder g_latency_recorder;
``` cpp
IntRecorder() : _combiner(std::make_shared<combiner_type>()),
_sampler(NULL) {}
explicit IntRecorder(const butil::StringPiece& name) : _sampler(NULL) {
expose(name);
}
IntRecorder(const butil::StringPiece& prefix, const butil::StringPiece&
name)
: _sampler(NULL) {
expose_as(prefix, name);
}
```
请问一下这里剩下两个构造函数不初始化_combiner是什么原因呢, 是有专门的设计还是只是写漏了?
