Remove pid file failed, if pid file name is longer than 64 on Linux

[jiedo]

Hi,

I find a problem, the pid file is left over after program exit . I check the code and find the file name is truncated.

syscall.Unlink(name) 

The size of symbolic link file in /proc is always 64, this buf may not longer enough.

    if fi, err = os.Lstat(path); err != nil {
        return
    }
    buf := make([]byte, fi.Size()+1)

    if n, err = syscall.Readlink(path, buf); err == nil {
        name = string(buf[:n])
    }

Thanks!
