At the moment the CMake package config is useless below CMake version 3.0 and should be disabled. Additionally exported targets should be prefixed by a namespace msgpack::.

The new spec introduces some new types for str/bin. Support for these types can be improved.

• There should be some way from the C API to deliberately emit a str vs a bin type. Currently the only pack function in userspace is msg_pack_raw, which as best as I can tell always emits str.
• There should be some way to detect whether a msgpack_object was decoded from a str or a bin type. Currently both str and bin formats get decoded to an object with object.type==MSGPACK_OBJECT_RAW.

The first problem is simple enough. As to the second problem, the decode logic seems be buried in macro hell, and I'm not really confident enough that I understand the existing flow to make an attempt.

This bug is important enough that in the absence of a simple solution I will end up writing a new library in the target language.

• Enhance CMakeLists.txt files.
• Move to Boost Test from Google Test to support pre-C++11 compilers.
• Add more configurations on CI matrix builds.
• Add support for the following types:
  • std::array<std::byte>
  • std::span<char>
  • std::span<unsigned char>
  • std::span<std::byte>

I plan to submit one more PR to add full support for std::span - a nice non-owning data range wrapper from C++20.

Hi, msgpackers:

I'm trying "zmq + msgpack-c" to make some prototype on our embedded systems. In principal, we have one device based on PowerPC, and another on ARM (armvt5). It works fine on PowerPC. However, if I send a message between two processes on ARM or send a message from PowerPC to ARM, I will see the "alignment trap" prints, like below.

Alignment trap: process (601) PC=0x000155d4 Instr=0xe1cc20d8 Address=0xb510450c FSR 0x001

Then, I want to know exactly where causes the problem, so I change the ARM build from release mode (-O2) to debug mode (no optimizations at all, so nothing). Surprisingly, the "alignment trap" prints do not show up.

I'm a bit stuck now and do not know which way to go. Any suggestions? Thanks!

Here is a small sample program that shows how include ordering can result in a significant amount of compiler errors. Forcing a strict ordering on includes seems to be a very poor approach:

#include <msgpack_fwd.hpp>

enum class color : int 
{
    red,
    green,
    blue
};

#include <msgpack/object.hpp>
MSGPACK_ADD_ENUM(color);
//#include <msgpack/object.hpp>

#include <msgpack.hpp>

int main(int argc, char** argv)
{
    msgpack::object o(color::red);
    return 0;
}

If you compile this program you will get the following output. Swapping out the msgpack/object.hpp includes will get rid of the errors.

The Debian armhf build of 3.3.0 is failing the mentioned test.

Since it's using EXPECT_TRUE() instead of EXPECT_EQ(), there's not much diagnostic information in the build log (although there are a lot of warnings in the build). I was able to reproduce the issue on one of our porter systems, and changed the assertion to

EXPECT_EQ(obj.as<std::chrono::system_clock::time_point>(), v);

I was hoping that would give more clarity about why the test failed, but instead the test passes whenever I run with that change.

If it helps, I could provide the annotated assembly that's generated for that test function.

Under Xcode 9.3, I'm not able to build msgpack-c because Xcode currently has C++17's optional under the experimental namespace.

/msgpack/include/msgpack/v1/adaptor/cpp17/optional.hpp

Line 19: #include <optional>

Xcode fails with the error "optional not found".

In my Xcode project, I have the following build settings:

• C++ Language Dialect: C++17 [-std=c++17]
• C++ Standard Library: libc++(LLVM...)

It would be super neat if I could use msgpack as a pure wire format reader/visitor without having to create a result msgpack::object.

For instance, my class msgpack_from_json_handler can be passed to rapidjson::Reader::Parse() as a parameter and will be called back on every element in the JSON tree.

With unpack_reference_func(), I can avoid copying all string data with a zone. However, I still have to let msgpack generate a msgpack::object tree, with allocations depending on the non-leaf objects / depth of the tree. In some situations, a simple visitor pattern would work better.

Here are two example use cases:

• Converting msgpack to a custom type/variant without allocations ("use case 1")

Elvis's library deals mostly with JSON data. Internally he stores much of his data as RapidJSON variant values. He decides he also wants to support serialialization to and from msgpack. He needs to process lots of data and packing/unpacking is a hot code path, so it needs to perform as fast as possible. For serializing to msgpack, he can use pack()/pack_map()/pack_array() functions and json-msgpack. He also wants to be able to read directly from a msgpack buffer into a RapidJSON variant, skipping the intermediate step of the msgpack::object because his variant can represent the same data in a format that the rest of his code uses.

[Note that instead of unpacking into JSON, one could also make use cases for msgpack::type::variant, known user-defined message objects, etc.]

• Checking msgpack contents without unpacking them ("use case 2")

Jakob wants to implement a SQLite extension function that checks if a serialized msgpack buffer (stored in a column of a SQLite table) contains a certain string. He wants to issue SQL queries such as, SELECT * FROM table WHERE msgpack_array_contains(msgpack_column, id) and implement the msgpack_column() extension function in the most efficient way, because it will be executed for a lot of rows. He would like to write a visitor class that gets called on each item and aborts unpacking when an array item equals id (after setting a found flag to true), or when the top-level msgpack type is something other than ARRAY. He does not care about a return type, neither msgpack::object nor any other variant.

I think RapidJSON's SAX interface (passed to rapidjson::Reader::Parse()) would be a pretty good starting point, with minor adaptations required to suit msgpack's object model. Here's an initial draft of a (template) interface for C++ classes implementing a msgpack visitor, and a suitable unpack() overload:

struct unpack_visitor {
    bool visit_nil();
    bool visit_boolean(bool);
    bool visit_positive_integer(uint64_t);

[Edit: changed begin_*() to start_*() as RapidJSON, Qt and the Java SAX API all use start as well.]

I prepended visit_ to single-value functions so we don't get issues with keywords (bool float(double);) or the Apple nil define, and msgpack's lower-case naming can still be employed.

The bool return value of all of those represents a successful parse (true for "continue parsing", false for "parse error"). The unpack() function is specified in a way that an exception-less interface can be built with it and all current unpack() functions can be implemented with this unpack() overload and a visitor:

• The zone and stack of result msgpack objects can be members of the visitor object, which uses/writes/manages them.
• Stream-level errors (parse_error and insufficient_bytes) are called as error functions in the visitor, which can decide to either throw or store them as state in the visitor object (and do custom error handling afterwards).
  • For use case 2: A caller who does avoids throwing exceptions can distinguish between legitimate parse errors and "found, now abort" early return situations by determining whether error functions have been called. If I know that my object is valid msgpack, an early return will save me some reads and processing time.
  • I chose to include offset parameters for the error functions, because it could be useful for error reporting (invalid bytes range from parsed_offset to error_offset). error_offset is the same value as the off parameter in unpack(). When used within an unpacker, parsed_offset equals parsed_size() and error_offset equals parsed_size() + nonparsed_size() (assuming I understand the purpose of these values correctly).
• unpack_limit and size_overflow errors can be thrown by the visitor functions themselves.
• unpack_reference_func can be called by visit_str(), visit_bin() and visit_ext().
  • user_data can be a member of the visitor class.
• unpacker can't be implemented on top of this overload because unpack() doesn't take a parse context object. (The visitor object likely contains a stack of msgpack objects, but does not tell the calling parser about the stack depth. That's a good thing because it makes the visitor object more lightweight and easier to implement if no stack information is necessary.) However, it should be possible to use the same visitor object for unpacker as for regular unpack() overloads, assuming that insufficient_bytes() doesn't throw.
• The off result parameter might be important for error messages. It's required here in addition to the visitor's error functions because if false is returned from a visit_*()/start_*()/end_*() function, the visitor itself does not know the current offset so it can't store it as state. Hence unpack() itself must maintain and return it.

Personally, I find this interface a lot more approachable and easier to understand than unpack_reference_func and unpack_limit. Even though it is simpler in concept, it is also more flexible. I hope something like this can be supported by msgpack-c.

I see there is fixes for correct type cast.

Previously within pack.hpp was declaraion:

void append_buffer(const char* buf, size_t len)
    { m_stream.write(buf, len); }

Now there is couple of compile time overloads to respect valid type cast when len parameter is not size_t. But, what if method ::write has overloads ? In this case &Stream::write will not be compiled (because compiler has ambiguity).

I have class Writer with 'primary' write method

virtual void write(const std::byte*, size_t size) = 0;

and second 'utility' method:

void write(const char* bytes, size_t size)
{
	write(reinterpret_cast<const std::byte*>(bytes), size);
}

Second method introduced especially to using with msgpack-c, but for first parameter compatibility. As temporary solution i remove second 'utility' method from my Writer class and 'fix' pack.hpp as

void append_buffer(const char* buf, size_t len)
{
    append_buffer(m_stream, &Stream::write, buf, len);
}

template<typename S, typename R, typename Ptr, typename Size>
static void append_buffer(S& s, R (S::*) (Ptr, Size), const char* buf, size_t len)
{
  s.write(reinterpret_cast<Ptr>(buf), static_cast<Size>(len));
}

So the concerns I raised in issue #164 turned out not to be a problem. However, more recently in the AutobahnCpp issue queue, @oberstet brought up another concern: the Apache 2.0 license isn't compatible with GPLv2. This is documented by the Apache Foundation itself: http://www.apache.org/licenses/GPL-compatibility.html

In short, GPL projects that use Apache-licensed libraries (i.e. msgpack-c) are in a legal gray zone and might not be safe to distribute. This is because GPL's copyleft clauses extend to header-only libraries (*), but GPL's clauses are not compatible with those of the Apache license so the resulting license would be invalid.

(*) according to one of several reasonable interpretations, including that of the FSF that wrote the GPL

In other words, GPL projects probably shouldn't use msgpack-c, at least not its header-only C++ part. This limits the possible adoption of msgpack. Other licenses, such as the Boost license or the MIT license, do not have this problem.

Please consider if this is something you want to fix. If you decide to take action, you need to get approvals of all copyright holders to change the license.

Hello,

I tried to build msgpack-c with Visual C++ 2010 on Windows7 64 bit. I used cmake(version3.0.2) and messages for configure/generate are shown below. Then I tried to build msgpack project in solution file (msgpack.sln) with Debug mode. But I encountered with many errors (error log is also attached though this is japanese).

I could compile msgpack with Visual C++ 2010 for msgpack-0.5.8 . But I could not compile msgpack for the recent version... I attached the log message on the compile also.

Can msgpack be compiled with Visual C++ 2010? Or only available for the recent compiler?

regards, Takahiro Matsumoto

How do you manage end of a message in a protocol ? I use msgpack-c and the only solution I found is to send the header before the payload (separately).

Send the header to client :

// header
{
  "message_type": "hello",
  "payload_size": 10
}

The client received the header, unpack it, and allocate a buffer of "payload_size", receive data from stream, and if the buffer is complete the message is finish.

I want to send header and body succinctly

{
  "header": { "message_type":"hello", "payload_size": 10},
  "payload": {...} // can come in multiple frame
}

My problem is that I don't know if it's possible to partially unpack the header for knowing the size before receiving the full message (splitted if > 4096kb due to libevent restriction)

How would you do that ? I am open to all solutions.

Is there anyway to control which fields are packed or unpacked on a call by call basis?

Can I do something like this?

struct C
{
    int a;
    int b;
    int c;
    MSGPACK_DEFINE_MAP(a, b, c);
};

C c1;
c1.a = 1;
c1.b = 2;
c1.c = 3;

msgpack::sbuffer buff;
msgpack::packer<msgpack::sbuffer> packer(buff);

// only pack fields a and b
std::string fields1[] = { "a", "b" };
packer.pack(c1, fields1);

// only unpack field a
std::string fields2[] = { "a" };
msgpack::object_handle handle = msgpack::unpack(buff.data(), buff.size(), fields2);
msgpack::object obj = handle.get();
C c2;
obj.convert(c2);

For better visibility of this issue I've switched to onluy man pages using patch

When sending a message like ddff000000, msgpack-c and msgpack-cpp allocate about 96GB of memory:

1. Load a large 32 bit int (0xff000000): https://github.com/msgpack/msgpack-c/blob/a9a48cea3a78ba661ee8096b5dab456361b0ff23/include/msgpack/unpack_template.h#L364
2. Call callback with the large int: https://github.com/msgpack/msgpack-c/blob/a9a48cea3a78ba661ee8096b5dab456361b0ff23/include/msgpack/unpack_template.h#L145
3. Compute allocation size (0xff000000 * 24): https://github.com/msgpack/msgpack-c/blob/a9a48cea3a78ba661ee8096b5dab456361b0ff23/src/unpack.c#L205
4. Allocate 96GB: https://github.com/msgpack/msgpack-c/blob/a9a48cea3a78ba661ee8096b5dab456361b0ff23/src/unpack.c#L215

In most situations, this is not a problem, because that memory isn't written to, so it's never mapped. However, if someone runs a networked program (e.g. a chat client using msgpack) under MemorySanitizer or AddressSanitizer, one of two things will happen:

1. Under msan, the user will see ERROR: MemorySanitizer: requested allocation size 0x2000000008 exceeds maximum supported size of 0x200000000 and the program will abort.
2. Under asan, the system will attempt to actually allocate 96GB of memory, because asan writes to all the allocated memory in __interceptor_malloc -> asan_malloc. If the user has swap enabled, this will soon cause thrashing, rendering the computer unusable. If not, the Linux OOM killer will come along and kill processes until more memory is available (hopefully it kills the chat client).

As an alternative, the code could allocate a smaller array at first and then exponentially grow it until it reaches the given size (similar to std::vector::push_back). If performance is a concern, you could limit this behaviour to arrays larger than some number (e.g. only for array_32s).
