Newtonsoft JSON.NET 6.0.8 和 Mac OSX 上的 Mono 以光荣的方式失败
Newtonsoft JSON.NET 6.0.8 and Mono on Mac OSX fails in glorious manner
我构建了一个大量使用 JSON 的分布式系统应用程序。该应用程序 运行 在 Windows(在 7、8、8.1、Server 2008、Server 2012 上测试)和带有 Mono
的 Ubuntu 14.04 上非常棒
但是,当我尝试在 OSX Yosemite 10.10.2(也许其他)上 运行 它时,该应用程序以光荣的方式失败了。我已经在独立的沙盒应用程序中隔离了对 Newtonsoft JSON.NET 和 运行 的一些调用,并且永远无法重现该问题。我在下面粘贴了调试信息,希望有人能在堆栈跟踪中看到某些内容,否则可能会指出一个明显的问题。

为简洁起见,我删除了一堆与线程相关的数据。全文可以在这里看到:https://gist.github.com/jchristn/677c53abc3c3028d804f
serialize_json方法如下(很简单):
public static string serialize_json(object obj)
{
return JsonConvert.SerializeObject(obj, Newtonsoft.Json.Formatting.Indented, new JsonSerializerSettings { });
}

有问题的 JSON 字符串如下所示:

"user_guid": "root",
"container_name": "home",
"size": 3259,
"num_objects": 1,

public string user_guid { get; set; }
public string container_name { get; set; }

public List<string> container_path { get; set; }

public List<obj_info> obj_metadata { get; set; }
}
这是在较旧的 Macbook Pro 上,但它有 Core 2 Duo 和 8GB 内存。机器上没有别的运行ning。
也尝试将 Mono 更新到 3.12.1,但它有同样的问题。
sh-3.2# which mono

我也在 Windows 上的 Mono 中尝试了 运行ning,但问题没有出现 (v3.12.1)。
我在iOS开发方面也有一些类似的奇怪经历。 (使用多任务和 JSON 时会出现这样的异常)
我发现将这些添加到 mtouch AOT 选项解决了我的问题:
nrgctx-蹦床=8096,nimt-蹦床=8096,ntrampolines=4048
希望它也能对您(以及其他开发人员)有所帮助。
