[zeromq-dev] Are bindings supposed to set linger on implicit close/destroy?

[Dylan Cali]

Hello,

The zguide states at the end of "Making a Clean Exit":

you need to shut down each socket that has ongoing requests. The proper way

> destroy a context, I'd suggest sending a patch. *

Yet I noticed the pyzmq bindings do not seem to follow this convention and
scripts that do not explicitly set linger themselves hang.  The pyzmq devs
closed this as a non-issue:

https://github.com/zeromq/pyzmq/issues/102

Conversely, both the czmq and jzmq bindings do set a low linger:

https://github.com/zeromq/czmq/issues/116
http://git.io/hBaf

So should this be considered a bug in pyzmq, and as a bindings author
should I follow the convention of setting a low linger?

Thanks much,
Dylan
