Guidence on #pragma once
by Robert Ramey 25 Nov '18

25 Nov '18

In the safe numerics library my *.hpp files start with the following boiler plate: #ifndef BOOST_NUMERIC_AUTOMATIC_HPP #define BOOST_NUMERIC_AUTOMATIC_HPP // MS compatible compilers support #pragma once #if defined(_MSC_VER) && (_MSC_VER >= 1020) # pragma once #endif ... I would like to replace all this in every file with just #pragma once according to https://en.wikipedia.org/wiki/Pragma_once#cite_note-9 this should be possible while supporting almost all which claim to be C++ 14 conformant. The exception noted is C++ for Cray. I realize that strictly speaking I shouldn't do this. But it would instantaneously remove some cruft from my code as long as the occasional error from repeating the same include guard text in multiple files. It might have some performance benefits and some other repercussions related to pre-compiled headers. Who knows what else. It would be interesting to know what others might have to say about this.

[Boost][DoubleEnded] Status?
by degski 25 Nov '18

25 Nov '18

We had the review of this library proposal/addition quite a while back and ever since I've been [eagerly] waiting for its official entry into Boost. https://github.com/erenon/double_ended does not show any activity and there is nothing in the Boost.Container going on either. What is the status? degski -- *“If something cannot go on forever, it will stop" - Herbert Stein*

Geometry path length breaking windows regression runs
by Tom Kent 23 Nov '18

23 Nov '18

There has been a change to the geometry library, sometime around Nov 14, that is causing the windows regression runners I manage to crash. The issue is that it is creating *very* long filesystem paths, even with the regression --abbreviate-paths option set. There are a bunch of files such as: D:\teeks99-08\run\results\boost\bin.v2\libs\geometry\test\self_contained_headers\self-contained-algorithms-detail-buffer-buffered_piece_collection~hpp.test\msvc-14.1\dbg\adrs-mdl-64\async-excpt-on\thrd-mlt\self-contained-algorithms-detail-buffer-buffered_piece_collection~hpp.obj.rsp That seem to be created alright, but when I try to cleanup the run afterwards, windows doesn't allow me to delete the files.

Help - my disk is full! (of bin.v2 stuff)
by Paul A. Bristow 21 Nov '18

21 Nov '18

I note with surprise (and alarm) that my Boost-stuff disk partition is nearly full! Closer inspection reveals that I have a bin.v2 folder of over 50 GB. Obviously, I need to delete something. What are the implications of deleting things? What is the best option? Should I simply delete the whole folder bin.v2 (I have, in desperation, gone nuclear some time ago) or just bin/v2/libs or ? Expert advice welcome. Thanks Paul --- Paul A. Bristow Prizet Farmhouse Kendal UK LA8 8AB +44 (0) 1539 561830

Rotating on-call review managers
by Zach Laine 19 Nov '18

19 Nov '18

Boost was originally created to incubate libraries that target eventual standardization. When new libraries are proposed, many of the Boost community members that participate in C++ Standard Committee (WG21) meetings ask "How many users does this have, and did you consider Boost first?" Often the answer is that they considered Boost but could not figure out what they were supposed to do to make that happen, or that they had difficulty finding a review manager. There are other things that can be done to make getting a library Boost-review-ready, but most of them require a bit of work up front. The review manager requirement is relatively easier to satisfy. This volunteer effort is to better facilitate Boost's value in the ISO C++ standardization process and so the reviewers would need to recognize intent to standardize the proposed libraries. Submissions that are supported with a paper in a mailing or a draft will make it easier to source a review manager from this queue, but authors without either are encouraged to get in contact with reviewers on this list to find out what that entails. This is the list of volunteers: Zach Laine Micheal Caisse Matt Calabrese Louis Dionne Vinnie Falco Glen Fernandes Jeff Garland David Sankel The list will rotate; the first person on the list will be "on-call". If you'd like to help, let me know and I'll add your name to the list. Also, I've made a PR that adds this list and a note like the description above to https://www.boost.org/development/submissions.html (#6 Seek a Review Manager): https://github.com/boostorg/website/pull/387 Zach
