on windows flyweight simple_locking is using std::mutex but it should be using std::recursive_mutex()
by Foelsche, Peter 30 Jun '23

30 Jun '23

Dear All, On windows flyweight simple_locking is using std::mutex but it should be using std::recursive_mutex. I've got this firing an exception due to _Check_C_return() getting passed something else than success (number 3). I've checked by implementing my own locking policy and it definitely shows that the code is attempting to hold more than a single lock in parallel on the same mutex. The secured set.erase() can cause further flyweights to be destroyed given a suitable recursive use of flyweight. Kind Regards Peter Foelsche PS. Thanks for boost!

<stdfloat> support in Boost.Math
by Matt Borland 28 Jun '23

28 Jun '23

Today support was added for C++23’s <stdfloat> types in Boost.Math. Please let us know if you run into any warnings or errors as we go through the release captures, and betas in the following weeks. There are two common issues that we found. The first is a stack overflow in GCC 13.1 from their internal type promotion system. This will be fixed in 13.2, and we have added workarounds for it. The second are warnings and errors from implicit conversions between types. We have fixed hundreds of instances of these throughout the code base. Thank you for your help as always. Matt

Regarding the MySQL and Redis formal reviews
by Vinnie Falco 28 Jun '23

28 Jun '23

Dear All, This is a brief update on some pertinent developments. Foremost, I want to acknowledge the exceptional contributions of Ruben Perez, creator of Boost.MySQL, and Marcelo Silva, the author of Boost.Redis. Their hard work in developing and refining their respective Boost libraries exemplifies the best qualities of authorship. They are actively engaged in the various channels of the public C++ Slack Workspace (https://cppalliance.org/slack/) collaborating and answering questions. Consider joining. To clarify a potential misunderstanding, Ruben joined the C++ Alliance team only after his library Boost.MySQL was accepted. Therefore, his subsequent affiliation had no bearing on the outcome of the review. Regarding Marcelo, he has always worked independently on Boost.Redis and has no contractual relationship with The C++ Alliance. Next, I'd like to laud Klemens for his unwavering diligence. As the review manager for these two libraries, he operates with impartiality and independence from the C++ Alliance with no financial recompense. The C++ Alliance policies precludes any author sponsored by us from acting as a review manager for a library that we also sponsor. This policy underscores our belief and commitment to the effectiveness and integrity of the Boost Formal Review process. In conclusion, our objective has always remained consistent: to fortify and expand Boost, and to support the author and maintainer community. The talent, dedication, and hard work invested in making Boost the best it can be is truly commendable. Our motivation is driven by passion for the language and open source. Together, we can make Boost even more remarkable. Yours sincerely, Vinnie

Adding Search Functionality to boost.org
by Mohammad Nejati [ashtum] 27 Jun '23

27 Jun '23

Hey everyone, One of the issues with the current Boost website is the absence of search functionality. This forces users to rely on search engines and use queries like `site:boost.org asio cancellation_slot` However, this approach has several problems. Firstly, it often displays outdated versions in the search results. Secondly, it lacks a proper hierarchical presentation to effectively guide users. Moreover, there is no way to filter the results for a specific library. To address this problem quickly, we have decided to create a search index for the existing HTML documents on the Boost website. However, we encountered a primary challenge during this process. We needed to extract contents with the correct hierarchy for each library to ensure that the search results were displayed in a hierarchical manner. For instance, the results will be shown as `Asio › Reference › Deferred_values › Requirements` This hierarchical presentation can significantly enhance the user experience. The Boost libraries utilize various documentation formats such as QuickBook, AsciiDoc, Doxygen, and even multiple handwritten formats. This diversity posed a challenge in creating a generic crawler script. To overcome this obstacle, we initiated the Boost.Gecko project. This project involved the development of 16 custom crawlers, tailored to extract search records from the 151 Boost libraries. We are currently utilizing the Algolia search platform to index search records, which offers a free plan for open-source projects. Algolia also provides a rich JavaScript library for building a search interface on the frontend. We have leveraged this library to design a customized user interface for the search box, enhancing the navigation of search results. I kindly request you try out the new search functionality by visiting the demo page at: https://cppalliance.org/boost-gecko/ and share your thoughts, suggestions, or any issues you may encounter. Your input will greatly assist us in refining the search feature and ensuring it meets the needs of our users. Please note that the drop-down for selecting a library is included to simulate the experience of being on a specific library page. Our plan is to incorporate a search button into the header of every library page, defaulted to search within that specific library. Demo page: https://cppalliance.org/boost-gecko/ Repository: https://github.com/cppalliance/boost-gecko/ Respectfully Yours, Mohammad Nejati ---- C++ Alliance Staff Engineer
