[GitHub] [PR] setting default branch to 'develop'
by Michel Morin 01 Nov '15

01 Nov '15

Hi, We sometimes forget to change the base branch of PR from 'master' to 'develop', even if we know PR should be made against 'develop' branch! To prevent from accidentally making PR against master branch, it'd be nice to **set the default branch to 'develop' branch** for Boost repositories on GitHub. (Then, the default base branch of PR would be set to 'develop' branch.) To change the default branch, it takes just a few clicks on web browser: https://help.github.com/articles/setting-the-… [View More]

[Config] BOOST_HAS_PTHREAD_MUTEXATTR_SETTYPE not defined in MACOS for GCC-5
by Vicente J. Botet Escriba 29 Oct '15

29 Oct '15

Hi John, I'm having an issue with gcc-5.1 on MacOs. BOOST_HAS_PTHREAD_MUTEXATTR_SETTYPE is not defined. I see that there are things like #if __MACH__ && !defined(_MSL_USING_MSL_C) ... # if (__GNUC__ == 4) // Both gcc and intel require these. # define BOOST_HAS_PTHREAD_MUTEXATTR_SETTYPE # define BOOST_HAS_NANOSLEEP # endif #else ... // BOOST_HAS_PTHREAD_MUTEXATTR_SETTYPE not defined here #endif Wondering why the GCC version must be 4 and why when _MSL_USING_MSL_C is … [View More]

[website] update version for Oracle Solaris Studio on the Boost website
by Aparna Kumta 29 Oct '15

29 Oct '15

The Boost1.59 page at http://www.boost.org/users/history/version_1_59_0.html under 'Compilers Tested' section, contains an entry for Sun( Oracle Solaris Studio). This needs modification for the upcoming Boost 1.60 release for which I would like to submit a PR. I looked at https://github.com/boostorg/website but not sure if this is the correct repository. Could someone please point me as to where I need to submit the PR? Thanks, Aparna

[graph] dijkstra pull request ping
by Piotr Wygocki 28 Oct '15

28 Oct '15

Dear all, this mail concerns this pull request: https://github.com/boostorg/graph/pull/13 which is currently over one year long. Maybe, the idea of the patch is unclear or needs some additional discussion. The patch solves the problem which arises when using no_init version on dijkstra algorithm and passing a custom distance_map. This algorithm is implemented as call to BFS, which is very unfortunate since it is not BFS. Maybe BFS could be seen as special case of dijkstra with custom … [View More]

Boost.Log 1.59.0 incompatible with MSVC option /Zc:wchar_t-
by Giel van Schijndel 28 Oct '15

28 Oct '15

Hi, I'm trying to build Boost.Log on MSVC9 (aka Visual Studio 2008) with the [/Zc:wchar_t-][1] option (necessary due to a vendor's SDK we're using). Unfortunately this fails to build. The mentioned option turns wchar_t into a typedef to unsigned short (i.e. it's not longer a distinct type). TLDR: My question _why_ is boost::log::aux::is_character_type<wchar_t> excluded when BOOST_NO_INTRINSIC_WCHAR_T is #defined? I see no harm in including it unconditionally. For some reason however, … [View More]

boost lockfree queue.hpp - alternate implementation w/o compare_exchange
by boost＠mccart.us 28 Oct '15

28 Oct '15

Is there any interest in an alternate implementation of a lockfree queue that doesn't use compare_exchange (assuming it is correct, or can be made to be correct)? I have a multi-producer / multi-consumer implementation that generally doesn't suffer nearly as much from contention. On my hardware (an older high-end 64 bit x86 workstation) I get roughly comparable throughput with existing boost lockfree queue with 1 producer and 1 consumer. With 4 producers and 4 consumers I get about 3x … [View More]
