Strange failure in regression matrix
by Alexander Grund 24 Mar '20

24 Mar '20

Hi, I got a failure of Boost.Nowide develop (and master) for msvc-14.0 in the regression matrix although that configuration is tested as far as I can tell. Furthermore there isn't any indication WHAT failed, see https://www.boost.org/development/tests/develop/developer/output/teeks99-09… Am I missing anything or is this a quirk of the regression tester? Thanks, Alex

Bug in Boost.Asio strand(strand<OtherExecutor>&& other)
by Niklas Gürtler 24 Mar '20

24 Mar '20

Hello, there is a bug in the Boost.Asio strand::strand(strand<OtherExecutor>&& other) move constructor as it tries to do an invalid cast on the wrong object. A friend declaration is also required to access the private members of the other strand. I submitted a PR https://github.com/boostorg/asio/pull/333 to address this issue. Regards, Niklas

Hi, can Boost.Optional be merged to master? There is even a CI failure on develop with a PR fixing this. So would be great if those could be merged shortly. Thanks

[config] Merging 'develop' to 'master' before the 1.73 release
by Edward Diener 23 Mar '20

23 Mar '20

Are the changes in config's 'develop' branch going to be merged to the 'master' branch before the 1.73 release ? The reason I ask is that a config 'develop' PR which I authored is a dependancy of the tti library, ans I can not merge the 'develop' changes of tti into 'master' unless those config changes also are merged to 'master'.

Re: [boost] Looking for Boost.uBlas data frames project GSoC mentors
by Tom Kwok 23 Mar '20

Hi CB, Thank you for your suggestions. I will continue with my proposal and start solving the competency test. David as of now still has not replied though. So I might need to request for mentorship for Boost uBlas data frame GSoC project here. Is anyone interested in offering mentorship and reviewing my proposal and questions?

[parameter][1.73] Library broken and unattended. Regressions and unmerged PR.
by Andrey Semashev 22 Mar '20

22 Mar '20

Hi, I'd like to draw attention to Boost.Parameter state. Since 1.71, it seems to be broken as described in these issues: https://github.com/boostorg/parameter/issues/91 https://github.com/boostorg/parameter/issues/97 The latter one was actually reported to me in Boost.Log, as this Boost.Parameter bug affected its users in a rather nasty way (the user's code silently compiles and has the wrong effect). For the latter issue I created a PR with a fix: https://github.com/boostorg/parameter/pull/99 which got no reply so far. The person who assumed Boost.Parameter maintenance and made the problematic changes, Cromwell D. Enage, is not responding, so the library is basically broken and unmaintained. I really don't want 1.73 to be released with a bug like the one affected Boost.Log, so I would appreciate if someone with merge permissions could merge my PR. If not, I will be forced to fork the library internally in Boost.Log for 1.73 (which I also really don't want to do). This would take care of my immediate concern. The other issue seems to be affecting users as well and I don't have the solution for it. Given that the library is unmaintained, it might be better to: 1. Move the current state of develop to a separate branch. 2. Revert master and develop to a state prior to Cromwell's commits that went into 1.71 (i.e. to the 1.70 state). This should take care of the Boost.Log issue as well, so it would be fine with me as well. Thanks.

github pull request process on non-owned submodule
by Jeff Garland 22 Mar '20

22 Mar '20

Sorry if this is obviously documented somewhere, but searches of mailing list aren't helping. I'm looking to submit a pull request for the icl library to remove dependencies on date_time compiled library -- in conjunction with changes to date_time on develop now. I've basically followed the cheat sheet on the wiki: https://github.com/boostorg/wiki/wiki/Getting-Started%3A-Cheat-Sheet but when I try to push my branch I get permission errors. Is there something I did wrong or is the icl repo setup wrong? Thx, Jeff jeff@jeff-mint193:~/dev/boost/libs/icl$ git push origin dt_nolib Username for 'https://github.com': JeffGarland Password for 'https://JeffGarland@github.com': remote: Permission to boostorg/icl.git denied to JeffGarland. fatal: unable to access 'https://github.com/boostorg/icl.git/': The requested URL returned error: 403
