Second, I assume the point of this approach is to avoid copying the callable object, and also support non-default constructible callables. My approach uses the original callable as a kind of prototype, from which it copies new objects for every operation. To be honest, I don't think there should be any difference in performance between my approach with copying and yours with constructing. Ergonomically, I think mine is better. Yours may be looking more straightforward to users. One idea came to my mind. It's sometimes hard to determine which parts of the SQLite C API are supported by your library, and what specific components do it. So, I think you need a dedicated list of all SQLite C functions with comments like "supported via sqlite::backup", "supported via sqlite::mutex", "not supported because an analogous function X is supported ", "not supported because deprecated by SQLite", etc.

[graph] Temporary maintenance delays until the new year
by Jeremy Murphy 18 Nov '24

18 Nov '24

Dear Boost.Graph users, I'm in the process of moving to another country and changing jobs at the moment, so apologies that there has been and will continue to be a period of slow responses to (some) pull requests, etc until I get settled into a new routine. Regards, Jeremy

Couldn't you achieve a similar effect (scoped to C++20 and later) by conditionally using concepts? In a way similar to what Asio does to diagnose completion tokens (i.e. BOOST_ASIO_COMPLETION_TOKEN_FOR).

Status of the 1.87.0 Beta Release
by Marshall Clow 12 Nov '24

12 Nov '24

There have been a couple of minor problems reported against RC2. However, yesterday we noticed that Boost.Parser was not part of the RC. We will be issuing an RC3 later today to rectify this. Unfortunately, this means that the beta release will be delayed by a couple of days — The Release Managers

Formal Review Retrospective
by Vinnie Falco 11 Nov '24

11 Nov '24

Ironically, a robust discussion regarding the review process and the usage of Slack is now taking place... on Slack. Arnaud made this suggestion which I am reposting here: "... formalizing a "Retrospective" phase as an actual part of the Formal Review could be key in avoiding criticism against the process to leak into criticism against the proposed library." I think this is a great idea. After each formal review result is announced, there is a new "retrospective" thread started which allows the community to reply and weigh in on how they thought the review was conducted. This actually happened organically in the last review of async-mqtt5 and I think it could be enhanced if the review wizard or review manager had pre-emptively started a retrospective thread where the replies could be accumulated. The subject line could for example be "[async-mqtt5] Review Retrospective" What do you think? Thanks
