That is how I convert it to string. After that I use the url in webkit
and the login message is only used in application.

That certainly seems to have worked. Thank you.

Visual studio builds seem to get broken quite a lot because of this.
Probably because the Travis CI doesn't support msbuild.

You have two choices:
1. Send the '\0' as part of the message (and set length to one more byte).
2. Append a '\0' after receiving the message.

Thanks for that! That fixed the login message, but it still sometimes
cuts off the end of the url. Is there a max length limit? It is approx.
126 characters long. It cuts off like 5-7 chars I think and replaces
them with the '@' followed by empty boxes as I said earlier.
Thanks,

Uh, why?
string(static_castchar*(reply.data()),reply.size());
doesn't assume the string is null terminated. It constructs string from pointer
and
Good point. Forgot about the specific details for that C++ constructor. The
null byte should not be required.
As Tom points out, you should print out what you are sending and receiving
(contents and length) and make sure it makes sense.

Well on my system the following line
printf(identity frame size: %ld bytes\n, zmq_msg_size(messageIn));
inserted before your line in multiPartMsg.h
id = *(static_castint*(zmq_msg_data(messageIn)));
yields 5 bytes.
The code at
https://github.com/zeromq/libzmq/blob/master/src/router.cpp#L465
Well, I've printed out size and it is correct. I've also shortened the
message by 5 characters and it stopped cutting off the last characters
(atleast I think it stopped, tried 15 times and it came correct every
time). So I think the problem was in the length of the message. I don't
know if it
No, this is not a (known) limitation. Did you print exactly what you are
sending and what you are receiving? My guess is you are putting a null byte in
the middle of what you are sending.

Yes, I've printed that message. There can't be any NULL byte there. It
is string success: appended with url. It is normal url like
http://example.org/path/to/jsp?lang=en_US?session=session id here.
That session ID contains numbers, characters and dashes.

the problem is in the std::string, because when I use

One point to focus on could be memory management: are you sure the messages you

When you create a message via zmq_init_data() (which zmq::message_t does
with the constructor args you specified, and specify NULL for the ffn
argument, it becomes a const message, which means that ZeroMQ assumes
ownership of the pointer you handed it (it's a cmsg type, e.g. *const*
data). It

Message goes out of scope, destructor called, receiving side is getting a
pointer to a free'd heap block.

Oh thanks a lot, didn't know this. So the correct way would be to have

I should rebuild it and delete it manually when I am done with the
socket, right? Or should I have (message_t*) for every message I use?

You can do something like -
zmq::message_t ackMessage(message.size());
std::copy_n(message.data(), message.size(), ackMessage.data());
This constructor form will cause the message to allocate it's own storage
(and thus free it appropriately), you then copy the contents of your string
into the
You see, this is why it always helps to ask for a minimal code sample; it helps
you refine your thoughts and it helps us to reason about your code.
You should look into the functions that implement a message’s lifecycle. You

You will need cast ackMessage.data() to char* (e.g.
static_castchar*(ackMessage.data())) for that to work.

I've used memcpy() since I am not using c++11.

Hi,

It crashes whether it runs with gevent threads or POSIX threads.
It crashes whether the DEALER in the master process talks over ipc or tcp
with the REP workers.
