Once the binding is more or less usable, definitely link it from 
zeromq.org website.

PUB/SUB is inherently unreliable, so messages can be lost even with 
"durable" sockets (say when the queue overflows).

Identifying gaps in message sequence can be done by sequence-numbering 
the messages on the publisher.

I bundle 32-bit and 64-bit versions with my old pre-release Windows

differences:

Also, try my ZeroMQ::Raw binding, which adds no extra code like the
other binding does.  It's basically a straight wrapper, with the sugar
layer in a separate module (AnyEvent::ZeroMQ::Handle).  The ZeroMQ
binding on CPAN does weird stuff like bake in JSON support, which I

Note I've only ever cross-compiled OpenPGM with MinGW on Ubuntu, I've never
tried on Windows in MSYS; Python shitting itself with fork doesn't help
trying to do anything with SCons as I found out with the Cygwin port.  You
can add the MinGW compiler dependencies into MSVC, they're listed here

OK, I've now extended the api.zero.mq site to hold the man pages for
all versions from 2.0.6.

Comments welcome... would people like this to replace the current

[zeromq-dev] Targeting ZeroMQ Interop (my C# wrapper) at ZeroMQ 2.1.0

2011-02-19 Thread Alex Forster 
I'm having a hell of a time compiling ZeroMQ 2.0.10 with support for OpenPGM 
2.1.27-pre2. I got it down to 18 linker errors, and then I hit a wall because 
those errors are all related to missing MinGW libraries, and I'm using Visual 
Studio. My options now are: (1) dump Visual Studio, install the entire MinGW 
toolchain, and recompile everything introducing a MinGW dependency in the 
process, (2) compile .lib versions of the MinGW libraries since the dist 
binaries are all .a, or (3) move my project to ZeroMQ 2.1.0 which purportedly 
has ABI stability (very enticing), and support for the latest version of 
OpenPGM (thus no dependencies on glib).

I've been taking a pretty thorough look at the commit log 
(https://github.com/zeromq/zeromq2/commits/master/) and at the issue log 
(https://github.com/zeromq/zeromq2/issues/labels/master) and it seems that 
2.1.0 is very stable.

I'm looking for (1) a general idea of how far along/stable 2.1.0 is, and (2) 
some feedback on how wise a decision it is to target my wrapper library at this 
development version.

Sure. This tool should be saved in a public git somewhere, either

When you get your hackish perl scripts stable, we can even run the

Generating from the documentation, using some hacky perl, then
uploading to the Wikidot site automatically using the Wikidot API.

Hi all,

Since people have randomly asked for this, I've built a site to hold
the man pages for the git master, at http://api.zero.mq/.

Comments welcome, I've tried to get a balance between the regular man
page style and the 0MQ web site look.

Thanks to Ian Barber for the *.zero.mq domains!

Fair enough.

Not sure what you mean with this. I'd rather add two methods to the
blob class, but it's defined just as a typedef now. Can we make that a
full class so I can do identity.print() and identity.printhex() to get
usable values to pass to the log() method?
