boost::bind 不能处理函数重载 (error: no matching function for call to 'bind')

前言

最近任务多、工期紧，没有时间更新博客，就水一期吧。虽然是水，也不能太失水准，刚好最近工作中遇到一个 boost::bind 的问题，花费了半天时间来定位解决，就说说它吧。

问题背景

项目中使用了 boost 的 ios_service，任务都是 post 到对应线程去执行，这样可以避免复杂的多线程同步问题，有点类似早年间 COM 的单线程套间模型。不过这就需要将接口通过 bind 封装为函数对象传递给 ios_service，之前的代码都工作正常，但我新增了一个接口后，却怎么也编译不过，报下面的错误 (超长内容，展开谨慎)：

错误看着挺唬人，其实关键的就是第一句：

jni/../../Task/jni/../jni/../../xxxx/jni/../xxxx_xxxxxxxxx.cpp:3414:48: error: no matching function for call to 'bind'         xxxxxxxxxxx::instance()->getIOS().post(boost::bind(&xxxxxxxxxxxxx::create_task,                                                 ^~~~~~~~~~~

boost::bind create_task 这个接口时出错了，百度了下这个错误，网上比较多的说法是 bind 给的参数和接口声明不一致，可是仔细检查了三遍参数，都没有发现问题，甚至把 post 改成直接调用的形式，这个就可以通过编译，真是神了~

另外查资料的过程中，发现 bind 最多支持 9 个参数，超过就不行了。不过在我的场景里，只有 4 个参数，所以也不是这方面的问题，可以排除。

排查过程

为了简化问题的排查过程，排除其它因素干扰，我写了一个简单例子：

#include <iostream> #include <functional>   using namespace std;   int create_task(int); int create_task(int, int);  int main(int argc, char* argv[]) {     auto f1 = bind(create_task, 1, 2);      f1();      return 0;  }  int create_task(int a) {     cout << "create_task (" << a << ") called" << endl;      return 0;  }   int create_task(int a, int b) {     cout << "create_task (" << a << ", " << b << ") called" << endl;      return 0;  }

 这里使用了 std bind 而不是 boost bind，不过一样可以复现出错场景，同时避免引入 boost 静态库导致 demo 太过复杂：

$ make g++ -Wall -g -c bindemo.cpp -o bindemo.o -std=c++11 bindemo.cpp: In function ‘int main(int, char**)’: bindemo.cpp:11:37: error: no matching function for call to ‘bind(<unresolved overloaded function type>, int, int)’      auto f1 = bind(create_task, 1, 2);                                       ^ bindemo.cpp:11:37: note: candidates are: In file included from bindemo.cpp:2:0: /usr/include/c++/4.8.2/functional:1655:5: note: template<class _Func, class ... _BoundArgs> typename std::_Bind_helper<std::__or_<std::is_integral<typename std::decay<_Tp>::type>, std::is_enum<typename std::decay<_Tp>::type> >::value, _Func, _BoundArgs ...>::type std::bind(_Func&&, _BoundArgs&& ...)      bind(_Func&& __f, _BoundArgs&&... __args)      ^ /usr/include/c++/4.8.2/functional:1655:5: note:   template argument deduction/substitution failed: bindemo.cpp:11:37: note:   couldn't deduce template parameter ‘_Func’      auto f1 = bind(create_task, 1, 2);                                       ^ In file included from bindemo.cpp:2:0: /usr/include/c++/4.8.2/functional:1682:5: note: template<class _Result, class _Func, class ... _BoundArgs> typename std::_Bindres_helper<_Result, _Func, _BoundArgs>::type std::bind(_Func&&, _BoundArgs&& ...)      bind(_Func&& __f, _BoundArgs&&... __args)      ^ /usr/include/c++/4.8.2/functional:1682:5: note:   template argument deduction/substitution failed: bindemo.cpp:11:37: note:   couldn't deduce template parameter ‘_Result’      auto f1 = bind(create_task, 1, 2);                                       ^ make: *** [bindemo.o] Error 1

其实看了这个 demo，很多人都会怀疑一个问题——是不是重载的 create_task 出了问题呢？确实如此，其实我只要将另一个 create_task 的声明注释掉 (实现仍保留)，这个 demo 就可以编译通过了，运行效果如下：

$ ./bindemo create_task (1, 2) called

不过我在当初查这个问题的时候可是费了九牛二虎之力，因为参数使用了引用类型，一开始怀疑是引用的锅，直接使用指针，不行；然后怀疑是没有为引用参数添加 boost::ref，也不行；最后直接把 bind 接口改成另外一个成员函数 (start_task)，无意中居然通过了。不过此时我仍怀疑是参数的问题，于是增加了一个同名的函数重载，参数照抄 create_task，结果就失败了；最神奇的是改为之前那版 start_task 也不行了，这才开始怀疑是函数重载的问题。

解决方案

知道了问题原因，改起来就比较顺了，因为新版的 create_task 增加了一个结构体作为参数，于是干脆将它重命名为 create_task_param，这样再绑定就没有问题了。

后记

问题虽然解决了，但是 bind 为何对重载函数如此“无能为力”呢？按理说根据提供给 bind 的参数，再匹配重载函数的参数列表，应该可以挑选正确的重载版本。

不过换个角度思考，bind 支持占位符，上面的例子中，我可以这样写：

int main(int argc, char* argv[]) {     auto f1 = bind(create_task, 1, 2);      f1();      auto f2 = bind(create_task, placeholders::_1, 0);      f2(3);      return 0;  }

其中 f2 有一个参数使用了占位符，这个参数将在调用时才传递，而 bind 需要在绑定那一刻知道使用的是哪个版本的 create_task，针对这个例子，他只有一个两参数的版本可选，但如果有多个两参数且第二参数为 int 类型的重载版本的话，bind 就迷糊了，毕竟他不知道后面用户会给占位符传递什么类型的参数不是？所以我猜测为了避免类似的问题，c++ 干脆不让 bind 支持重载函数，直接出错了事，编译期错误总比运行期错误好解决，你觉得呢？

当然，比较迷的是，这里只有一个两参数的版本，bind 仍然报错了，这是够懒的。另外有些网上的文章说 (附录 4)，bind 会挑选重载函数中第一个声明的版本，如果通过就通过，如果不通过就报错。但是我实际测试的情况是，无论将两参数的版本放在前面还是后面，都报错，除非不声明，看起来我这个 gcc 版本是严格执行了 c++ 标准滴~
