[contract] help marking regression test expected failures
by Lorenzo Caminiti 27 Oct '17

27 Oct '17

Hello all, I need some help with marking some Boost.Contract regression tests as expected failures. I don't understand why my explicit-failures-markup.xml: https://github.com/boostorg/boost/blob/develop/status/explicit-failures-mar… Doesn't math the expected failures I see on the regression report: http://www.boost.org/development/tests/develop/developer/contract.html For example, the following from explicit-failures-markup.xml (around line 887) should marked old-if_copyable test as an expected failure on msvc-11.0: ... <mark-expected-failures> <test name="old-if_copyable"/> <test name="old-if_copyable_macro"/> <toolset name="gcc-gnu-4.7.2"/> <toolset name="gcc-gnu-4.7~c++11"/> <toolset name="gcc-mngw-gnu-4.6c+"/> <toolset name="gcc-mngw-gnu-4.7c+"/> <toolset name="msvc-10.0"/> <toolset name="msvc-11.0"/> <note author="Lorenzo Caminiti"> Test fails because this complier version does not properly implement SFINAE causing incorrect errors on substituion failures for private and protected members (this seems to be fixed in GCC 4.8 and MSVC 12.0). </note> </mark-expected-failures> ... But the old-if_copyable test still shows up as a failure on the regression test report: http://www.boost.org/development/tests/develop/developer/output/teeks99-08-… Any idea what I am doing wrong? Thank you. --Lorenzo

path length too long for 64 bits builds
by Vicente J. Botet Escriba 27 Oct '17

27 Oct '17

Hi, we have an issue since we have added threadapi= . On 64 bits windows machines we are seen Austin Beer said in https://github.com/boostorg/thread/pull/188#issuecomment-339829423 "FYI, the 64-bit Windows builds are failing due the unit tests exceeding the 260 character filepath limit on Windows. Every filepath includes |\msvc-14.1\debug\address-model-64\threadapi-win32\threading-multi|. Do you know if there is an easy way to shorten this? On the 32-bit builds the filepaths don't have |\address-model-64| which is just enough to keep them under the 260 character limit so they don't fail." Is there a workaround to this issue without changing the specific part of the test files folder structure? Best, Vicente

Boost::iostreams dual-use seekable filter

I see dual-use filters and seekable filters, but I can't find an example of a dual-use seekable filter. Any help digging me out of template error heck would be appreciated.

Seems like I need write-access to merge a PR
by Fernando Cacciola 25 Oct '17

25 Oct '17

Hi, It's been a lifetime since I last worked on Boost, and I'm lost as to the current procedures with the repository. I've been looking into this open ticket: https://svn.boost.org/trac10/ticket/12972 and noticed this open pull request: https://github.com/boostorg/numeric_conversion/pull/7 but even though I'm logged with my Github account, it appears I don't have write-access to merge this PR. I tried the wiki but seems to have way too much information. Can you simplify the steps needed, these days, to fix a bug on a library? specially if someone else already created a PR as in this case? TIA -- Fernando Cacciola SciSoft Consulting, Founder http://www.scisoft-consulting.com

Help wanted: Open pull request reminders
by Beman Dawes 25 Oct '17

25 Oct '17

As a library maintainer, I'd like to get periodic reminders of open pull requests for libraries I maintain and perhaps some other libraries I'm interested in. I'd like a email reminder, but others might prefer Slack or other forms of notification. A related need is for anyone to be able to find the total number of open pull requests for Boost as a whole, and perhaps get a sorted list of the per library counts. Or maybe we should just show today's count on the web site? Googling for "github open pull request reminders" shows that lots of others feel the same need. Would someone like to volunteer to review what others are doing to meet this need, and recommend an approach suitable for Boost? --Beman

Software packages using boost require the TR1 header files in order to build, but the TR1 header files are no longer available in version 1.65.1 ! What is going on ? Regards, Guido

[regression tests] feature request: UI integration of bjam requires clause
by Joaquin M López Muñoz 25 Oct '17

25 Oct '17

Hi, Boost regression tests as run by run.py can be explicitly disabled through two different mechanisms: 1. By marking the disabled toolsets with <mark-unusable> in status/explicit-failures-markup.xml. 2. By adding a requires clause in the corresponding Jamfile.v2 file. For instance, in Boost.PolyCollection C++11 is mandated through project : requirements [ requires cxx11_noexcept ] # used as a proxy for C++11 support ... (https://github.com/boostorg/poly_collection/blob/develop/test/Jamfile.v2 ), which results in non-C++11 toolsets being effectively disabled. The problem is that both mechanisms show very differently in the HTML report: http://www.boost.org/development/tests/develop/developer/poly_collection.ht… Toolsets disabled through markup appear grayed out wth a "n/a" legend and an (optional) link to an explanation of why the toolset doesn't work, whereas tests blocked by Jamfile's requires just show a blank column. Would it be possible to modify the regression test HTML reporting utility so that Jamfile-blocked toolsets show also as "n/a" in gray or something similar? The possibility of also adding a link to a custom explanation would be a boon, but I guess this is much harder. This would greatly increase the readability of the reports, particularly by non-savvy users who are likely to deem blank columns as just missing tests that might eventually be filled up. Many thanks, Joaquín M López Muñoz

RFC.. Steering Committee Bylaws Proposal
by Rene Rivera 24 Oct '17

24 Oct '17

It has become clear to me, and some others, that the recent decisions of the Steering Committee have exposed various problems with how the Steering Committee operates. At CppCon I met with some of the Steering Committee and expressed the concerns with them. I also explained, from my experience in other organizations, how such issues are managed. The result of that is that I will be proposing the Steering Committee adopt operating Bylaws. But before formally presenting them to the Steering Committee I'd like get feedback on them <http://bit.ly/2hI22DN>[1]. The Bylaws hopefully address some key issues that I feel are at the core of the current problems: * Decisions can be made without input from interested parties. * Opaque selection of members. * No recourse by library authors to correct problems. This follows the original goals of the formation of the formation of Steering Committee of being transparent and responsive < http://bit.ly/2yoL5Ij>[2].

boost timer, warnings, backlog
by James E. King, III 24 Oct '17

24 Oct '17

I'm seeing a warning for use of "long long" in a lot of builds, originating in Boost.Timer. I like warning-free builds, so this is something I would like to see resolved. There's an issue in Boost Trac for it: https://svn.boost.org/trac10/ticket/12996 There's a pull request open since April for it (and 3 more going back a couple years): https://github.com/boostorg/timer/pull/4 Is this module still actively maintained? Thanks, Jim
