library maintainer list
by Robert Ramey 24 Dec '17

24 Dec '17

I'm curious about how I might go about discovering and contacting the person(s) who might be maintaining a particular library. As an example, I have a couple of questions about possible enhancements to the boost interval library (what about making this constexpr?). Ideally, I'd like to see a summary page for each library which steers me to the appropriate links like issues, comments/issues page, maintainence status etc. such as the boost library incubator has. Actually, I considered just adding these pages to the boost library incubator website, but I didn't have the motivation and it might stir a pot I personally don't want to stir right now.

[date_time] Trac 13194 - %e posix time_input_facet specifier behavior
by James E. King, III 21 Dec '17

21 Dec '17

https://svn.boost.org/trac10/ticket/13194 Just looking at this one, and looking at the documentation, it states that %e is the same as %d however when the value is less than 10, a leading space is to be used instead of a leading zero. The example in the description has a flaw, I believe, and I commented on that. Do folks agree with my comment? Should parsing fail if it says "December 5" (with one space) and the format string is "%B %e"? Valid input would be "December 5" (with two spaces). I also found that the code blindly ignores delimiter specifiers, so I opened a github issue for it: https://github.com/boostorg/date_time/issues/53. Comments appreciated there as well. Thanks, Jim

[endian] undefined behaviour in boost.endian
by Arvid Norberg 21 Dec '17

21 Dec '17

Hi, I've submitted an issue to the github project for boost.endian. I'm starting to wonder if this is in fact not the preferred channel for reporting issues. There are at least two separate issues causing undefined behaviour to be invoked in boost.endian. The first one is fundamentally based on the assumption that if the target architecture is x86, the C++ alignment requirements don't apply. I've posted more details here: https://github.com/boostorg/endian/issues/21 with a proposed patch here: https://github.com/boostorg/endian/pull/22 The second issue involves shifting negative integers, both invoking implementation defined and undefined behaviour. I don't have a patch to fix the issue, just to extend the tests to exercise the problem, which is then detectible with the undefined behaviour sanitizer. Patch is here: https://github.com/boostorg/endian/pull/24 I would really appreciate it if someone could review these and/or suggest a better venue than github to propose patches. thanks! -- Arvid Norberg

[release] 1.67.0 open for merging
by Daniel James 19 Dec '17

19 Dec '17

The master branch is open for merging all stable changes from develop, including bug fixes and major upgrades to existing libraries. Breaking changes should be coordinated via the mailing list with the developers of the other libraries affected. New libraries may be added, but require permission of a release manager. In other words, merging does not require permission from a release manager, except for new libraries.
