I'm trying to get a Boost review scheduled for the proposed Boost.OpenMethod. I sent an email directly to review wizards but haven't gotten a response. Can anyone help me get in touch with the wizards?

[bloom] Candidate Boost Bloom library: request for endorsements
by Joaquin M López Muñoz 09 Apr '25

09 Apr '25

Hi, I've been working during the last few months in a library I would like to propose for Boost: Repo: https://github.com/joaquintides/bloom Docs: https://master.bloom.cpp.al/ (Candidate) Boost.Bloom provides the class template boost::bloom::filter that can be configured to implement a classical Bloom filter as well as variations discussed in the literature such as block filters, multiblock filters, and more. #include <boost/bloom/filter.hpp> #include <cassert> #include <string> int main() { // Bloom filter of strings with 5 bits set per insertion using filter = boost::bloom::filter<std::string, 5>; // create filter with a capacity of 1'000'000 **bits** filter f(1'000'000); // insert elements (they can't be erased, Bloom filters are insert-only) f.insert("hello"); f.insert("Boost"); //... // elements inserted are always correctly checked as such assert(f.may_contain("hello") == true); // elements not inserted may incorrectly be identified as such with a // false positive rate (FPR) which is a function of the array capacity, // the number of bits set per element and generally how the boost::bloom::filter // was specified if(f.may_contain("bye")) { // likely false //... } } If you deem the library interesting and think it stands a chance of being accepted into Boost, allow me to request your endorsement. Best, Joaquin M Lopez Munoz

Call traits

Hi All Has the meat of Boost Call Traits ever made it into the stdlib? It seems like an obvious candidate, but I can't see it. Stdlin <type_traits> seems to be a very different offering, but maybe I'm missing something? Kind Regards Rob.

Which boost version/Asio fully supports Windows XP and how to build that from source?
by Dennis Luehring 04 Apr '25

i want to migrate an old dirty legacy app handling TCP/IP to Boost.Asio because all my other TCP/IP stuff is using Asio and the legacy app getting reworked BUT it still needs to run on old dirty Windows XP - for around 1-2 years (then i can upgrade to more recent compiler/Boost etc.) i know that i had used Boost (i think 1.69) on XP a long time ago and trying to find out what Boost version is the last XP supporting and how i can build boost from source with VS2022 + v141_xp toolkit (if that is even possible - i have no idea) im using boost on daily basis and build for Linux,Windows for over a decade so its just the Windows XP thing that makes mit nervous tried building Boost 1.69 seems to be possible with VS2022 x86 console with v141_xp toolkit installed (not tested with XP so far) boostrap.bat vc141 and i think that is minimal needed for Asio b2 release toolset=msvc-14.1 define=BOOST_USE_WINAPI_VERSION=0x0501 --with-system --with-thread --with-date_time --with-regex --with-serialization stage toolset can be set to anything currently (even msvc-14.1_xp or msv-14.1_blabla) so im not sure what i really need to force using the v141_xp toolkit so what is the latest Boost version that supports XP enough for Asio use and how to build that one properbly? thanks for any help
