NOTE! If you have no problem with RESTinio-0.7.1 there is no need to update to v.0.7.2. An update may be necessary if you manage RESTinio's dependencies by yorself.

v.0.7.0

This is the first significant release since v.0.6.13 and there are several breaking changes.

  • Switch to C++17. Since v.0.7.0 RESTinio requires C++17 as the minimal C++ standard.
  • Switch to nodejs/llhttp library for parsing HTTP requests. Previous versions of RESTinio used nodejs/http-parser, but it is now deprecated and no longer maintained. Since v.0.7.0 RESTinio uses nodejs/llhttp.
  • No more external projects for optional, variant and string_view. After switching to C++17 RESTinio uses std::optional, std::variant and std::string_view. Note that for the expected class RESTinio still needs the expected-lite project as a dependency.
  • Switch to Catch2 v3. The Catch2 library is used in RESTinio for testing. The first versions of Catch2 were header-only, but since v3 the Catch2 needs to be compiled as a library. Since v.0.7.0 RESTinio uses Catch2 v3 and can’t be used with previous versions of Catch2 library.
  • The Clara library is no longer used in RESTinio samples/tests/benchmarks. Parsing of command line arguments in some samples/tests/benchmarks becomes more simple and arguments with long names can’t be shortened now. It means that if --address is required then it can’t be specified as --addr.
  • The RapidJSON/json_dto libraries are no longer used in RESTinio samples/tests/benchmarks.
  • CMake is now the only build system supported. The previous versions of RESTinio used CMake and our own Mxx_ru build systems. Since v.0.7.0 only CMake is used. But Mxx_ru is still in use for managing dependencies.
  • RESTinio's CMake scripts have been refactored significantly. Most of the old CMake variables/options used for the configuration (like RESTINIO_FIND_DEPS) have been removed. There are several new variables/options that have to be used since v0.7.0: RESTINIO_ASIO_SOURCE, RESTINIO_DEP_STANDALONE_ASIO, RESTINIO_DEP_BOOST_ASIO, RESTINIO_DEP_LLHTTP, RESTINIO_DEP_FMT, RESTINIO_DEP_EXPECTED_LITE and so on. Please see the corresponding section in the documentation for more details.
  • Several classes/methods/functions marked as deprecated in previous versions are now removed.
  • The core restinio/all.hpp header file has been deprecated. It will be removed in v.0.8.0. The new core restinio/core.hpp header file must be used instead.
  • The format and behavior of restinio::on_pool_runner_t::stop changed. Now it may accept on_error-callback. The default on_error-callback calls std::abort if an exception is thrown in http_server_t::close_async.
  • Added support of chains of asynchronous handlers. Please see the corresponding section in the documentation for more details.
  • Added a basic support for chunk extensions in incoming requests.

v.0.6.17

Since v.0.6.17 RESTinio can be used with fmtlib in FMT_ENFORCE_COMPILE_STRING mode. In this mode FMT_STRING macro has to be used for format string in C++11/14/17 for compile-time checking of format string validity.

Now RESTinio checks the presence of FMT_ENFORCE_COMPILE_STRING and uses FMT_STRING when it's required.

NOTE. FMT_ENFORCE_COMPILE_STRING has to be defined before inclusion of any of RESTinio's headers.

fmtlib-9.1.0 in now used inside RESTinio (and included in restinio-0.6.17-full.* archives).

v.0.6.16

This release adapts RESTinio to fmtlib-9.0.0.

Since v.0.6.16 RESTinio can be used with fmtlib-8 or fmtlib-9, but fmtlib-8 is still used in RESTinio development.

NOTE: restinio-0.6.14-full.* archives contain asio-1-21-1, fmt-8.1.1 and catch-2.13.9. Versions of 3rd party libraries in restinio/third_party updated to the latest versions:

expected-lite at commit 34524d46e538f1e6ed114d8f8409f7cd173d96e6.
optional-lite at commit ea502a6472c85dbc0174764df218a0c3443c6772.
string-view-lite at commit f7aca36f5caa05e451f6887aa707df89197e6de6.

This is a maintenance release.

A fix for CMake script for case when RESTINIO_FIND_DEPS=ON and RESTINIO_FMT_HEADER_ONLY=OFF (#159).

Usage of std::aligned_storage_t in implementation of writable_item_t has been removed (it's deprecated in C++23).

In some places std::launder is used (if available) to avoid UB accessing a pointer after placement new.

NOTE: restinio-0.6.14-full.* archives contain asio-1-21-1, fmt-8.1.1 and catch-2.13.9. Versions of 3rd party libraries in restinio/third_party weren't upgraded.

v.0.6.13

This version introduces a couple of new big features and contains several changes some of that can affect existing code.


A new value not_handled added to request_handling_status_t enumeration (+ new helper function request_not_handled()). This value should be returned if a request-handler doesn't accept nor reject the current request and some other request-handler should be tried (if such a handler exists). If all request-handlers called for request processing return not_handled then RESTinio treats that value as rejected.


It's possible now to incorporate some additional (extra) data into a request-object. To do so a user has to perform the following steps:

Define a type for holding such an extra data:

struct per_request_data {
  user_indentity user_info_;
  ...
};

Define a extra-data-factory that should look like:

struct my_extra_data_factory {
  using data_t = per_request_data;
  void make_within(restinio::extra_data_buffer_t<data_t> buf) {
    new(buf.get()) data_t{};
  }
};

Or, if extra-data-factory is a simple and stateless object as shown above:

using my_extra_data_factory = restinio::simple_extra_data_factory_t<per_request_data>;

Specify my_extra_data_factory in server's traits:

struct my_traits : public restinio::default_traits_t {
  using extra_data_factory_t = my_extra_data_factory;
};

Change the format of request-handlers this way:

restinio::request_handling_status_t request_handler(
  const restinio::generic_request_handle_t<per_request_data> & req);

// or

restinio::request_handling_status_t request_handler(
  const restinio::generic_request_handle_t<my_extra_data_factory::data_t> & req);

Extra-data is available inside a request-handler via new method request_t::extra_data:

restinio::request_handling_status_t request_handler(
  const restinio::generic_request_handle_t<per_request_data> & req)
{
  auto & ed = req->extra_data();
  ...
}

See the documentation for more details.


It's possible now to bind several synchronous request-handlers into a chain (somewhat similar to ExpressJS's middleware):

#include <restinio/all.hpp>
#include <restinio/sync_chain/fixed_size.hpp>

auto incoming_req_logger(const restinio::request_handle_t & req)
{
  ... // Perform logging.
  // Allow the passing of the request to the next handler.
  return restinio::request_not_handled();  
}

auto mandatory_fields_checker(const restinio::request_handle_t & req)
{
  ... // Perform all necessary checks.
  if(!ok) {
    // Negative response has to be sent.
    return req->create_response(restinio::status_bad_request())
      ...
      .done();
  }
  // Allow the passing of the request to the next handler.
  return restinio::request_not_handled();  
}

auto permissions_checker(const restinio::request_handle_t & req)
{
  ... // Check user credentials and permissions.
  if(!ok) {
    // Negative response has to be sent.
    return req->create_response(restinio::status_unauthorized())
      ...
      .done();
  }
  // Allow the passing of the request to the next handler.
  return restinio::request_not_handled();
}

auto actual_processor(const restinio::request_handle_t & req)
{
  ... // Do actual request processing.
  return restinio::request_accepted();
}

struct my_traits : public restinio::default_traits_t {
  // Change the type of request handler.
  using request_handler_t = restinio::sync_chain::fixed_size_chain_t<4>;
};

restinio::run(restinio::on_this_thread<my_traits>()
  .port(...)
  .address(...)
  .request_handler(
    // Enumerate all handlers in the chain in the order of invocation.
    incoming_req_logger,
    mandatory_fields_checker,
    permissions_checker,
    actual_processor)
  ...
);

When a new incoming request will be parsed the RESTinio will call incoming_req_logger, then mandatory_req_logger, then (if necessary) permissions_checker, and only then (if necessary) actual_processor.

See the documentation for more details.
