高速公路 Python 0.9.3-3 引发与 "subscription_revocation" 相关的异常

Question

我是运行 Autobahn Python 0.9.3-3，我遇到了一个奇怪的错误，我不知道为什么。这似乎只发生在较新的 Autobahn Python 客户身上。有什么想法吗？

我怀疑将 Autobahn 升级到 0.10.x 系列会解决这个问题，但不幸的是，有一些向后不兼容的更改似乎无法快速解决。

Answer 1

这是服务器中的一个错误，它似乎接受任意 "features" 并将它们用作参数。这些新功能可能是在 0.9.3 版本之后的某个时间引入的。

如果有人有同样的问题，我 created a patch 反对 0.9.3-3。

此外，如果您对某个问题投反对票，最好能解释一下您这样做的原因，这样我以后可以改进提问。
