[boostbook] cleanup / modernization
by James E. King III 18 Jul '18

18 Jul '18

I would have opened an "issue" on the boostorg/boostbook project, however, that is not enabled. (Perhaps someone should enable it?) I have duplicated the boostbook setup scripts into the docker setup environment for Ubuntu Bionic and I have found that all of the packages that boostbook depends on are ancient.

[iostreams] libstdc++ vs MSVC exception handling behavior in seekg, seekp
by James E. King III 17 Jul '18

17 Jul '18

I found a disabled test in Boost.Iostreams called stream_state_test. It was disabled because it was thought it only tests the standard library implementation. Partially true, but it also tests some parts of iostreams so I have been working to re-enable it along with the generic CI upgrades. It looks like libstdc++ and the standard library that comes with MSVC (is it still Dinkumware? It used to be...) handle exceptions on stream seekg and seekp differently. I haven't consulted the … [View More]

Safe Float design question
by Damian Vicino 17 Jul '18

17 Jul '18

Hi, I looking for some design advice. The context: - I'm revisiting SafeFloat after some time and, while doing so, I'm rethinking all the decisions from the past. Idea is to sent for review in the following months. - The goal of the library is being a drop-in replacement for float, that adds checks to floating point operations and reports when a check failed. Without SafeFloat, someone could write something like this: #include <iostream> #include <limits> #include <cfenv> … [View More]

[system] Clang CI builds broken because of constexpr
by Andrey Semashev 17 Jul '18

17 Jul '18

Hi, I'm seeing these errors in Travis CI builds with Clang 3.8, 3.9, 4.0 and 5.0: ./boost/system/error_code.hpp:232:41: error: constexpr constructor never produces a constant expression [-Winvalid-constexpr] BOOST_SYSTEM_CONSTEXPR explicit std_category( boost::system::error_category const * pc ): pc_( pc ) ^ ./boost/system/error_code.hpp:232:41: note: non-constexpr constructor 'error_category' cannot be used in a constant expression /usr/… [View More]

[graph] disjoint_sets
by James E. King III 17 Jul '18

17 Jul '18

Hello folks in the Boost.Graph team, The CMT currently maintains Boost.DisjointSets which contains a class that is only used by Boost.Graph and Boost.GraphParallel. The headers are published in "boost/pending" right now. Given the CMT has a considerable workload already I would like to discuss moving disjoint_sets into Boost.Graph, as long as it satisfies the requirements for the two repositories currently consuming it. This would be for 1.69.0. Any thoughts, objections, considerations on … [View More]

Heads up about future standards annexing new identifiers
by Marshall Clow 16 Jul '18

16 Jul '18

As facilities get added to the standard library, they need names. When this happens, it restricts what other developers can and cannot do in their programs. For example, one cannot do this and expect most anything in the standard library to work: #define allocate(T) . new T [ But you knew about that ]. What you may not have known about was that the standards committee has voted contract enforcement/checking facilities into the draft standard (which will probably be C++20). This includes … [View More]

Searching for a intrusive::avltree_algorithms/bstree_algorithms dev
by Thimothée Virgoulay 16 Jul '18

16 Jul '18

Hello I'm working with the boost library (intrusive: : avltree_algorithms/bstree_algorithms ) and I found some bugs (not sure, maybe it's me who haven't understood the algorithm logic ). I have made hotfixes , add functions and it's working. But I don't know if this change were fine or needed. So I 'm searching for someone who can exchange with me about this library. Thimothée Virgoulay, second's year master degree in Bioinformatics at Montpellier University, France.

[rational] 1.68.0 merge permission
by James E. King III 16 Jul '18

16 Jul '18

The addition of pow() for rational was identified as a problem in beta testing. It has been reverted for now, and an issue added to the github repository to revisit it after 1.68.0. There are two commits I would like to merge to master: 1. The revert of pow which caused problems 2. A CI-only change to .travis.yml that fixes codecov.io and coverity scan build jobs in light of recent security upgrades in travis CI. No production code changes, zero affect on the release build workflow. This … [View More]

[CMT] 1.68.0 merge permission
by James E. King III 16 Jul '18

16 Jul '18

The CI builds in CMT repositories are failing since Travis CI updated their backend last week. The fix is simple and isolated in the .travis.yml file in each repository which is not part of the boost release build cycle. All repositories develop branch have been updated with the fix. I'd like to merge the fix in the CMT repositories into master to eliminate the remaining failed build indicators. Given the change is only in .travis.yml I hope that will be acceptable. Without the fix any … [View More]
