MQTT Tcl API中的错误？

问题描述：

source mqtt.tcl 

proc message_callback { topic message } { 
    puts stderr "message on topic $topic: $message" 
} 

set client [mqtt new] 
$client connect my-client $::addr 
$client subscribe {BCDS/#} message_callback 

vwait _done

运行一个简单的用户客户端和正常工作与当地的券商，如。蚊子在同一个局域网上运行（至少在运行时没有发现问题）。

但与互联网上的经纪人，例如。 iot.eclipse.org，打印一对夫妇的消息后

它在10秒内未能堆栈跟踪

1507901608909 (::oo::Obj22_coro): can't read "msgid": no such variable 
while executing 
"dict set rc msgid $msgid" 
    (class "::mqtt" method "receive" line 35) 
    invoked from within 
"my receive" 
    (class "::mqtt" method "listen" line 27) 
    invoked from within 
"my listen"

我调试表明，该API不通过连接手柄连接消息？我对么？有没有人使用这个API来做任何实质性的事情？

尝试将客户端id my-client改为random，以确保它不与现有客户端冲突。 – hardillb

只有一个连接，它打印一些消息，但在10秒内失败。修改了我原来的帖子。 –

答

这可能是一个错误。这不是报告错误的好渠道;堆栈溢出是针对更一般的支持问题。

但是，您可以方便地链接到Fossil软件包的存储库，因此您可以在这里报告错误（Fossil非常喜欢）。这是一个机票 → New ticket，您可以匿名登录并在该点报告机票（如果需要，请留下您的联系方式;如果需要，可以让作者与您取得联系）。

如果你已经检查过你建议你会看到我的票的链接。 –
