1 Introduction

ZeroMQ 4.0 bindings

API reference resides at http://orivej.github.io/pzmq/doc/index.html

See examples in examples.lisp.

Merits

• Everything is documented, at least preliminarily.
• Handles interrupts in blocking calls, thanks to Max Mikhanosha: msg-send and msg-recv interrupted by GC are automatically restarted (option *restart-interrupted-calls*).

Deficiencies

Everything not in examples.lisp or tests.lisp has not been tested.

Only those conveniences used in examples and tests have been designed and implemented.

Raw performance has not been fully optimized. This optimization probably matters only for 50000 messages per second or more of 10 kbytes or less, though.

Barebone automatic tests.

Special features (on top of basic features)

• WITH-CONTEXT and WITH-SOCKET accept options for CTX-NEW and SETSOCKOPT.
• WITH-CONTEXT establishes *DEFAULT-CONTEXT* for brevity in WITH-SOCKET.
• WITH-SOCKET establishes *DEFAULT-CONTEXT* when context is neigther specified nor found. Nesting single socket in a context is rather common; combining them together in a single form fits nicely into the common WITH-* paradigm.

5 Definitions

Definitions are sorted by export status, category, package, and then by lexicographic order.

5.1 Exported definitions

5.1.1 Special variables

Special Variable: *default-context*

Implicit context from @fun{WITH-CONTEXT} for @fun{WITH-SOCKET}.

Package

pzmq

Source

lisp-api.lisp (file)

Special Variable: *restart-interrupted-calls*

When blocking ZMQ call returns with EINTR automatically retry it, instead of signaling a condition.

Explanation: Every time garbage collection happens in implementation that use signals to stop threads (like SBCL), every ZMQ blocking ZMQ call, will error out with EINTR on every GC.

When this variable is non-NIL, PZMQ will retry the call, as if you had selected CONTINUE restart.

Note that EINTR will also be returned by any other interruptions such as attaching a debugger to a thread, or pressing Ctrl-C.

If you would like to terminate your ZMQ call in these cases, then rebind *RESTART-INTERRUPTED-CALLS*, and have a HANDLER-BIND set it to NIL on these special cases.

Then at a lower level, ignore EINTR errors. It is important to use HANDLER-BIND and not HANDLER-CASE, because we want the ZMQ function being interrupted to return EINTR, performing any necessary cleanups, using HANDLER-CASE or using non-local exit from HANDLER-BIND will accomplish its task, but without letting ZMQ call properly cleanup after itself.

c-api.lisp (file)

5.1.2 Macros

Macro: with-context NAME-AND-OPTIONS &body BODY

Initialize and terminate ZMQ context around body.

Use NIL for @em{anonymous context}, stored in @variable{*DEFAULT-CONTEXT*}.

Omit @fun{WITH-CONTEXT} altogether, and @fun{WITH-SOCKET} will establish it by itself.

Note: unwind-protected @fun{CTX-TERM} will not return until all governed sockets have sent all queued messages, unless they limited their wait time with :LINGER socket parameter.
@arg[name-and-options]{name | (name options)}
@arg[name]{name | NIL}
@arg[options]{:io-threads INT :max-sockets INT; as per @fun{CTX-SET}}

Package

pzmq

Source

lisp-api.lisp (file)

Macro: with-message NAME &body BODY

Macro: with-poll-items NAME (&rest ITEMS) &body BODY

Prepare POLLITEM array in NAME.

Without parentheses, an item indicates subscription to both :pollin and :pollout. @arg[items]{(item ...)}
@arg[item]{name | (name [:pollin] [:pollout])}

Package

pzmq

Source

lisp-api.lisp (file)

Macro: with-socket NAME-AND-CONTEXT TYPE-AND-OPTIONS &body BODY

Initialize and close ZMQ socket around body. Type is one of the types accepted by @fun{SOCKET}. Options are passed to @fun{SETSOCKOPT} one by one.

When TYPE is :SUB, and :SUBSCRIBE is not given in OPTIONS, imply subscribe to all. If this is undesirable, provide :SUBSCRIBE NIL.

When context is not specified, it either comes from surrounding @fun{WITH-CONTEXT} or @fun{WITH-SOCKET} in @variable{*DEFAULT-CONTEXT*}, or is established by this @fun{WITH-SOCKET} and stored in @variable{*DEFAULT-CONTEXT*} for the timespan of this block.
@arg[name-and-context]{name | (name context)}
@arg[type-and-options]{type | (type :option1 value1 :option2 value2 ...)}
