Thank you for your comment.

 

This feature is very needed for https://github.com/mosquito/aio-pika/pull/327.

 

PS How to send response on this message? I don’t see this message on mail.python.org.

And where do you find RLock?

Тема: Re: [Python-ideas] Add close method to queue

 

I was just looking for something similar, but this was already requested and rejected for lack of use cases here: https://bugs.python.org/issue29701.

 

For my own use case, a RLock with a class variable indicating the queue was closed did the trick.

I have a problem with notifying all current subscribers and new subscribers about the closure of the queue and the reason. For example, I have a producer that reads messages from websocket or something else and send this to a queue, and several consumers (I do not know how many). If any exception occurred, then all current subscribers and subscribers which will be added later should know about this error. I tried to send an exception to a queue, but that did not help, because I have several consumers. Also, this will not protect new consumers. I propose to add a new close method with exc argument, which will throw an exception when calling the get method, and also throw an exception for all current _getters.
