GetLogLen crash求助

[BokiceLee]

公司的几个项目都用了xlog打日志，每天都会出现少量的崩溃(参见以下崩溃信息)，类似#204的问题，如果#204的问题是sdcard读写问题的话，iOS应该不会有这种情况发生吧。
目前本地复现不出crash，苦苦分析不出问题，只能来这里求助了。
(崩溃信息，与业务逻辑相关的信息已屏蔽，望谅解～)

[garryyan]

能看到用户的存储使用情况吗？SIGBUS 和 mmap 有关的一般是越界访问了 mmap 的空间，之前有过类似的，是空间不够用了。

但是 xlog 会提前占位空间的。分析分析用户的共性吧

[BokiceLee]

终于看到一个有用的日志，大致是getloglen的同时由于另一个线程调用了exit，使得全局对象mmap_file被析构了，因此getloglen调用的mmapfile是closed了(析构函数中调用了close)的。想问一下，因为sg_cond_buffer_async已经有做过相关的处理，mmapfile为什么不做处理呢？是未考虑到还是有其他原因？(求回复。。。)

[garryyan]

mmapfile为什么不做处理呢?

指的哪方面的处理

[BokiceLee]

全局对象改成全局引用，防止exit时对象析构的不可控

[garryyan]

sg_cond_buffer_async 也只在 windows 上这么做了，因为在 windows 上能稳定重现这个问题。

你这个问题的解决办法 不妨尝试下 atexit 注册下 appenderClose

[BokiceLee]

xlog在appender_open中是已经注册了appender_close的了吧，这应该是多线程相关的问题，见线程14和23，线程14调用了appender_close，线程23同时析构了mmap_file对象，导致了appender_close及线程1中getloglen的mmap_file指针为空，

嗯 多线程问题，你可以在你那里改成引用，然后灰度看看数据会不会变好，如果变好提个 pr 过来。因为目前微信是没这种类型的crash 的，我们是hook 了 exit 代码，在 exit 中释放各种资源，然后再调用系统的 exit
