Richard's August Update

New Debugging Feature in Asio and Beast As covered previously, Boost 1.74 brought an implementation of the new unified executors model to Boost.Asio. Support for this is not the only thing that is new in Beast. Chris Kohlhoff recently submitted a PR to Beast’s repository demonstrating how to annotate source code with the BOOST_ASIO_HANDLER_LOCATION macro. I have since followed up and annotated all asynchronous operations in Beast this way. In a normal build, there is no effect (and zero...

Richard's July Update

Boost 1.74 - Progress Update Boost 1.74 beta release has been published and the various maintainers are applying last-minute bug fixes to their libraries in readiness for the final release on 12th August. For us in the Beast team, a fair amount of attention has been spent monitoring last minutes changes to Asio, as Chris makes the final tweaks after the Unified Executors update I mentioned in last month’s blog. Comprehensive Testing Last month I committed what I hoped would be the firs...

Krystian's July Update

What I’ve been doing I’ve been spending a lot of time working on optimizing the parser; perhaps a bit too much. Nevertheless, it’s very enjoyable and in doing so I’ve learned more than I could hope to ever learn in school. In addition to the optimization, comment and trailing comma support finally got merged, and I implemented UTF-8 validation (enabled by default, but it can be disabled). UTF-8 validation Prior to implementing this extension (or rather, feature which can be disabled), the ...

Krystian's May & June Update

Overview I’ve been very busy these last two months getting Boost.JSON ready for release, hence the combined blog post. Now that things are winding down, I hopefully can get back the normal blog release schedule. Boost.JSON Aside from a couple of personal projects, the vast majority of my time was spent getting Boost.JSON set for release. Breaking it down, this consisted of three main tasks: a tag_invoke based value conversion interface, parser optimizations, and support for extended JSON s...

Richard's May/June Update

Boost 1.74 - Interesting Developments in Asio We’re currently beta-testing Boost 1.74, the lead-up to which has seen a flurry of activity in Asio, which has impacted Beast. Recent versions of Asio have moved away from the idea of sequencing completion handlers directly on an io_context (which used to be called an io_service) towards the execution of completion handlers by an Executor. The basic idea being that the executor is a lightweight handle to some execution context, which did what t...
