This prevents hangs caused by `ctx.term()` if sockets are left open, but means that unclean destruction of contexts (with sockets left open) is not safe if sockets are managed in other threads. .. versionadded:: 25 Contexts can now be shadowed by passing another Context. This helps in creating an async copy of a sync context or vice versa:: ctx = zmq.Context(async_ctx) Which previously had to be:: ctx = zmq.Context.shadow(async_ctx.underlying) zdict[int, Any]sockoptsNr _instance int | None _instance_pidFr _socketsztype[_SocketType] _socket_classrself SyncContext io_threadsintcdSNrr-r/s r __init__zContext.__init__Qs:=#rcdSr2rr3s r r4zContext.__init__Ts=@Srshadow Context | intcdSr2r)r-r6s r r4zContext.__init__Ws?Bsrr int | Contextrrcbt|tr|}d}d}|rLd|_||_t|ts |j}n#t $rYnwxYwt|}nd|_t ||i|_ t|_ dS)NrrTF)r/r6) isinstancer _shadow _shadow_objr0 underlyingAttributeErrorrsuperr4r'r r+)r-r/r6shadow_address __class__s r r4zContext.__init__Zs j' * *  FJ  !DL%D fc** #.FF%D*622NN DL J~FFF   sA AAct|js^tsY|jsTd|_t ,t |ddt d|td||dSdSdSdS)a)Deleting a Context without closing it destroys it and all sockets. .. versionchanged:: 24 Switch from threadsafe `term()` which hangs in the event of open sockets to less safe `destroy()` which warns about any leftover sockets and closes them.

Most single-process applications have a single, global Context. Use this method instead of passing around Context instances throughout your code. A common pattern for classes that depend on Contexts is to use a default argument to enable programs with multiple Contexts but not require the argument for simpler applications:: class MyClass(object): def __init__(self, context=None): self.context = context or Context.instance() .. versionchanged:: 18.1 When called in a subprocess after forking, a new global instance is created instead of inheriting a Context that won't work from the parent process.

Context termination is performed in the following steps: - Any blocking operations currently in progress on sockets open within context shall raise :class:`zmq.ContextTerminated`. With the exception of socket.close(), any further operations on sockets open within this context shall raise :class:`zmq.ContextTerminated`. - After interrupting all blocking calls, term shall block until the following conditions are satisfied: - All sockets open within context have been closed. - For each socket within context, all messages sent on the socket have either been physically transferred to a network peer, or the socket's linger period set with the zmq.LINGER socket option has expired. For further details regarding socket linger behaviour refer to libzmq documentation for ZMQ_LINGER. This can be called to close the context by hand. If this is not called, the context will automatically be closed when it is garbage collected, in which case you may see a ResourceWarning about the unclosed context.
