Zero-malloc memory pool for Boost Intrusive smart pointers
by Francesco 22 Mar '19

22 Mar '19

Hi all, I have developed for my needs a C++11 memory pool that can provides C++ object instances in the form of boost::intrusive_ptr<> that automatically return to the pool once their refcount goes to zero. I found the need for such memory pool to have a zero-malloc memory pool algorithm for some performance-oriented applications that were relying on std::shared_ptr<>. Here's the link in case anybody is interested: https://github.com/f18m/boost-intrusive-pool with some (initial) benchmark as well. I thought that this may be useful to anybody else already using Boost intrusive pointers as well... Any comment is welcome! Francesco Montorsi

compile error, boost_1_70_0_b1, C++17, MSVC 1916, "/Zc:noexceptTypes-" compiler flag
by Thomas Wollenzin 20 Mar '19

20 Mar '19

Hello, We came across a compiler error with Boost version 1.70.0 b1 when compiling via MSVC 1916, C++17 standard and the "/Zc:noexceptTypes-" compiler flag set. The resulting error is of type: boost\type_traits\detail\is_member_function_pointer_cxx_11.hpp(359): error C2953: 'boost::is_member_function_pointer<Ret(__cdecl C::* )(Args...)>': class template has already been defined boost\type_traits\detail\is_member_function_pointer_cxx_11.hpp(48): note: see declaration of 'boost::is_member_function_pointer<Ret(__cdecl C::* )(Args...)>' A corresponding issue was created here: https://github.com/boostorg/type_traits/issues/118 We're wondering of the chances of getting this fixed with the final 1.70 release and if possible would like to get priority on a fix. Thanks for your time!

Update to problem of http::request call failing
by Osman Zakir 20 Mar '19

20 Mar '19

Hi. I still have the same exception, but I did notice something I was doing wrong: the API endpoint and the key for the request to the currency API were wrong. I fixed them, but the exception is still there. I sent an email to the OpenSSL users mailing list to ask them if I did anything wrong in the root certificate stuff. Entire source code for app is on GitHub here: https://github.com/DragonOsman/currency_converter .

Using async_pipe as named pipe in windows
by parean 20 Mar '19

20 Mar '19

I have this code: boost::asio::io_service ios; std::vector<char> buf(20); bp::async_pipe ap(ios, "\\\\.\\pipe\\SamplePipe"); boost::asio::async_read(ap, boost::asio::buffer(buf), [](const boost::system::error_code &ec, std::size_t size) {}); ios.run(); Now, I execute "echo 42 > \\.\pipe\SamplePipe" in the cmd and expect an asynchronous read to the buffer to occur. But instead I get the following error: "All pipe instances are busy." I'm sure I'm doing something wrong. Can you please tell me what should I add to my code for it to work? -- Sent from: http://boost.2283326.n4.nabble.com/Boost-Users-f2553780.html

multi_index reserve but allocate
by Olivier Tristan 20 Mar '19

20 Mar '19

Hi, Looks like that even if I call reserve on a multi_index, it stills allocate memory while I am still below the reserve size. Is this the intended behavior ? If so, what is the best way to avoid allocation in a fixed sized multi_index Thanks ! -- Olivier Tristan Research & Development www.uvi.net

Call to boost::beast::http::write() Failing with Exception "Uninitialized"
by Osman Zakir 19 Mar '19

19 Mar '19

Hi, everyone. I really need some help here. I tried looking at the Boost documentation as well, but I only saw that "http::write" from Boost.Beast throws a "system_error" exception on failure. I can't figure out why it's failing or what exactly is uninitialized. I did look in the debugger and I added the SSL stream object and the request object to the watch to check their respective values. I have this source code file: https://github.com/DragonOsman/currency_converter/blob/master/currency_conv… and this is the root_certificate.hpp file: https://github.com/DragonOsman/currency_converter/blob/master/root_certific… . Is there anything wrong in the root certificate verification code and such in the header file? And I'm trying to make a HTTPS GET request in the functions "cache_storage::query_rate" and "cache_storage::query_list" using those certificates through SSL context but my try-catch block in that second-mentioned function is catching a "system_error" from "http::write()". The "what" string is "Uninitialized", and from looking at the HTTP request object's value member, I noticed that it's just an empty string. I also tried to print out the request body before but got nothing from the request object in my app's console window at all (by "console" I of course mean the kind opened for Windows Console Applications). So could it be that the request object is uninitialized? I have this for that: " std::string host{ "bankersalgo.com" }, api_endpoint{ "/currencies_list" }, key{ currencykey }; std::string target = api_endpoint + '/' + key; std::string port{ "443" }; int version = 11; " and " // Set up an HTTP GET request message http::request<http::string_body> req{ http::verb::get, target, version }; req.set(http::field::host, host); req.set(http::field::content_type, "application/json"); req.set(http::field::accept, "application/json"); req.set(http::field::user_agent, BOOST_BEAST_VERSION_STRING); //req.set(http::field::content_encoding, "gzip"); // Send the HTTP request to the remote host http::write(stream, req); " The line setting the content encoding is commented out because I wanted to see what happens if I don't set the encoding to "gzip" (on bankersalgo.com, it shows that the content encoding for the HTTP response for each request endpoint is "gzip"). Also it seems the call to "http::write()" isn't necessarily failing since I do get a "200 OK" response. There's just an empty string both for the request object value and request body, and for the response body. But is it really the request object that's uninitialized? If so, why? I did add the code to set and I also did it exactly as shown in the example. It's also possible that the stream is what's uninitialized since there's a pending read and a pending write on it and both of them have empty data objects. How do I fix this stuff? Someone please help. Full app source code is here: https://github.com/DragonOsman/currency_converter .

Networking TS + Beast, NEW Tutorials, Read this to learn std::net !!!
by Vinnie Falco 18 Mar '19

18 Mar '19

Fellow C++, Boost, and WG21 Enthusiasts, lend me your ear! I write to inform you about exciting developments in C++ networking. First, a bit of background. Networking comes in three flavors: * Networking TS <https://cplusplus.github.io/networking-ts/draft.pdf> * Boost.Asio <https://www.boost.org/doc/libs/1_69_0/doc/html/boost_asio.html> * Standalone Asio <https://github.com/chriskohlhoff/asio> These three are for the most part identical, except that Asio flavors have additional features like ssl::stream and signal_set which are not in the TS, but will very likely appear in a future update or version. We've had Asio for over a decade now, but there is a shortage of experts. Some people believe this shortage is because Asio in particular (and thus, Networking TS since they have identical interfaces) is "difficult to use." I believe it is wrong to blame Asio for this. Concurrent programs in general are hard to write. This is applicable: "Unfortunately, today's reality is that only thoughtful experts can write explicitly concurrent programs that are correct and efficient. This is because today's programming models for concurrency are subtle, intricate, and fraught with pitfalls that easily (and frequently) result in unforeseen races (i.e., program corruption) deadlocks (i.e., program lockup) and performance cliffs (e.g., priority inversion, convoying, and sometimes complete loss of parallelism and/or even worse performance than a single-threaded program). And even when a correct and efficient concurrent program is written, it takes great care to maintain — it's usually brittle and difficult to maintain correctly because current programming models set a very high bar of expertise required to reason reliably about the operation of concurrent programs, so that apparently innocuous changes to a working concurrent program can (and commonly do, in practice) render it entirely or intermittently nonworking in unintended and unexpected ways. Because getting it right and keeping it right is so difficult, at many major software companies there is a veritable priesthood of gurus who write and maintain the core concurrent code." - Herb Sutter, "The Trouble with Locks", <http://www.drdobbs.com/cpp/the-trouble-with-locks/184401930> Although this was written in 2005 it is still relevant today. It is understandable that Asio will be the first target of anger and frustration when writing concurrent programs, since it is on the "front line" so to speak. There has also been a distinct shortage of *good* tutorials and examples for Asio. Articles or blog posts which teach you step by step, explaining everything, and giving example code which demonstrates best practices. Boost.Beast is my low-level HTTP/WebSocket library which builds on Boost.Asio: <https://github.com/boostorg/beast> In the original release of Beast, the documentation stated "prior understanding of Boost.Asio is required." However, field experience has shown that users ignore that requirement and attempt to write complex, concurrent programs as their first-time introduction to both Beast and Asio. Based on feedback from committee members, and to serve users better, the scope of Beast has been enlarged to include first-time users of networking. The upcoming Boost 1.70 release reflects this new scope and I am excited to announce some very nice things which you can access today. First of all, Beast documentation and examples no longer use the "boost::asio" namespace, they the namespace alias "net::". While this is cosmetic, it reinforces the notion when inspecting code that it is equally applicable to Boost.Asio, Asio, and Networking TS (identifiers which are not in the TS, such as signal_set, are still qualified with boost::asio). A new documentation page explains the three flavors of networking: <https://www.boost.org/doc/libs/master/libs/beast/doc/html/beast/using_io.ht…> This is also explained in my 2018 CppCon presentation: <https://youtu.be/7FQwAjELMek?t=444> I have added a "Networking Refresher", a complete overview of networking from soup to nuts. No prior knowledge or understanding of networking is required, everything is explained in detail so if you want to learn this is the place to start. I also kept it short, but it is loaded with hyperlinks for further learning: <https://www.boost.org/doc/libs/master/libs/beast/doc/html/beast/using_io/as…> There was a recent paper in Kona, P1269R0 ("Three Years with the Networking TS") about difficulty of implementing timeouts. To address this, Beast now has a stream class which implements configurable timeouts for you, and callers no longer have to fiddle with timers manually anymore. Everything "Just Works." It achieves the P1269R0 author's goal of having timeouts "built-in to asynchronous operations", but in a way that fits in with the design of the TS: <https://www.boost.org/doc/libs/master/libs/beast/doc/html/beast/using_io/ti…> I feel that this `beast::basic_stream` serves as an existence proof that the current design of Networking TS is sound - the TS offers a flexible toolbox which lets you build your own framework the way that you want it, without making odd choices for you. We are still discovering ways of leveraging it to maximum use. The beast::websocket::stream also has built-in timeouts, but they are enhanced to support "idle pings" (keeping client connections alive) and everything is fully configurable: <https://www.boost.org/doc/libs/master/libs/beast/doc/html/beast/using_webso…> All you need to do to get sensible, suggested websocket timeouts is add one line of code after creating your stream: ws.set_option(websocket::stream_base::timeout::suggested( beast::role_type::server)); To address the cumbersome boilerplate of writing composed operations (specifically the need to propagate the associated allocator and associated executor, and to avoid invoking the completion handler from within the initiating function when the operation would complete immediately) Beast adds two new utility base classes, with plentiful documentation and examples throughout: <https://www.boost.org/doc/libs/master/libs/beast/doc/html/beast/using_io/wr…> There are two well-rounded examples which show you step by step how to write these things in a safe way: <https://www.boost.org/doc/libs/master/libs/beast/doc/html/beast/using_io/wr…> <https://www.boost.org/doc/libs/master/libs/beast/doc/html/beast/using_io/wr…> I have a big, new open source project which implements a server, that uses the `system_context`, taking full advantage of native Windows and Mac OS system-level execution context features. To support this use case and industry feedback, the examples in Beast now default to being always thread-safe. All examples use a "strand", and leverage P1322R0 ("Networking TS enhancement to enable custom I/O executors"). Yes, this paper which was approved in Kona, is now implemented in both Boost.Beast, and Boost.Asio, including all of the Beast examples, so if you pick up Boost 1.70 (or the master branches from github) you can start playing with this as soon as you're done reading this message!! <http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p1322r0.html> We have an active #beast channel in the C++ Slack (https://slack.cpp.al) where experienced users can help, no question is too small! I hope you will join me and the rest of the Beast and Asio community in exploring what the very powerful Networking TS and Asio libraries have to offer, and build something great together! Regards P.S. Don't forget to star the repository! <https://github.com/boostorg/beast>

boost::endian::native_to_big_inplace fails with char
by Martijn Otto 18 Mar '19

18 Mar '19

I am having issues with boost::endian:native_to_big_inplace when used with a char. Whatever you try to 'reverse' comes out as 0. Looking through the code, on little endian machines it calls endian_reverse (as expected). This function has no overload for a char and it then gets promoted to an int. Since the int _is_ actually larger than 1 byte, something gets reversed. The native_to_big_inplace then returns it as a char, narrowing the int and throwing away all the relevant bits, resulting in a 0. I found an issue on github about this: https://github.com/boostorg/endi an/issues/10 about exactly this issue. The bug is easily shown if you try to compile static_assert(sizeof(boost::endian::endian_reverse('y')) == sizeof('y'))
