[chrono] Stopwatches
by Daniel James 15 Jul '14

15 Jul '14

Hi, What's the status for stopwatches? Because it's in chrono's metadata file, it's in the list at: http://www.boost.org/doc/libs/master/ Which will also put it in the release documentation list. But there's no documentation to link to, the headers don't get linked by 'b2 headers', and the tests don't seem to be running. Daniel

[git] Releases tags
by Adam Wulkiewicz 14 Jul '14

14 Jul '14

Hi, Is there a global policy regarding the way how/when/by whoom tags are created for releases and release candidates? In each submodule there are tags corresponding to the releases (e.g. boost-1.54.0-beta1, boost-1.55.0, etc.). Are they created somehow globally? When a tag is created for the main module is it automatically a tag of the submodule? Or must tags be created manually/separately in each submodule? Of course not counting some private tags. If the former is true, I'm guessing that private tags should have the names reserved for the releases tags? If the latter is true, are they created by the maintenance team or should the authors handle it themselves? Regards, Adam

[optional] can I merge a performance bug fix?
by Andrzej Krzemienski 14 Jul '14

14 Jul '14

Hi, Could I still merge this pull request for Boost.Optional for 1.56 release. https://github.com/boostorg/optional/pull/6 It fixes a negative performance impact added since 1.55 in cases like: consumeOptional(*produceOptional()); This code already used to seat in develop before I added a bug) and all tests passed fine. Now, the fix has been there since friday on develop and I have no test failures. Can I merge it to trunk? Regards, &rzej

[range] Is it conceivable to have it extended?
by Vladimir Batov 14 Jul '14

14 Jul '14

boost::iterator_range is a great concept/class but it does not seem to play efficiently with certain input sequences and seem to be too strong a requirement for certain algorithms. I have an old-fashioned C string in mind (I am sure there are other examples) and traversing algorithms. When I tried deploying boost::iterator_range for string-to-int conversion purposes, I quickly realized that I was traversing the string twice -- first to find the end and second to do the work. What I think is missing is the "parent" concept of a "sequence". Say, template<iterator_type, sentry_type> struct sequence { iterator_type begin(); sentry_type sentry(); }; Then "range" would implement and refine the "sequence" concept by template<iterator_type> struct range : sequence<iterator_type, iterator_type> { iterator_type begin(); iterator_type end(); sentry_type sentry() { return end; } } I.e., as "range" implements/is the "sequence", the boost::iterator_range will have one additional "useless" sentry() method. That way all the old code (using and/or needing end()) would still work but traversing algorithms might gradually adapt to only require "sequences" instead of "ranges": template<typename Iterator, typename Sentry, typename Function> Function for_each(Iterator beg, Sentry sentry, Function fun) { for (; beg != sentry; ++beg) fun(*beg); return fun; } That means that now all "open-ended" (with no known "end") "ranges" (they are not even "ranges" in the strict meaning of the word but rather "sequences") can be handled efficiently. I ended up having such an "extended" range in Boost.Convert (to handle C string traversals efficiently) but I hate having/maintaining the code and much prefer the standard solution. Any suggestions? Vladimir.

Libraries failing across the board.
by Beman Dawes 13 Jul '14

13 Jul '14

Marshall is just a few days away from being able to put out a beta release candidate. (And that is very good news!) But we still have too many libraries failing across the board on master: accumulators interprocess numeric/ublas pool proto spirit/repository spirit/test tr1 wave See http://www.boost.org/development/tests/master/developer/summary.html What is the hold up with these? Does anyone need help? --Beman

1.56.0 beta 1 release candidates available for testing
by Marshall Clow 13 Jul '14

13 Jul '14

Release candidate files for 1.56.0 beta 1 are available at http://boost.cowic.de/rc/ As always, the release managers would appreciate it if you download the candidate of your choice and give building it a try. Please report both success and failure, and anything else that is noteworthy. This helps ensure the candidates build OK before we push them out to SourceForge. The files (and associated md5s) are: MD5 (boost-1_56_0b1_rc1.7z) = a23e0b5f503c82970c9754dbc8324256 MD5 (boost-1_56_0b1_rc1.tar.bz2) = c6c8486dde4375896f302bdfe1fd3d2f MD5 (boost-1_56_0b1_rc1.tar.gz) = 1042e97a9f354b7187326fa1f9eb313e MD5 (boost-1_56_0b1_rc1.zip) = 984a70feac785d908d8f75ea9d8d2158 Since this is the first post-git release, we are expecting some teething pains with this release. Please test extensively. Thank you. --The release managers

Where is this symbol defined?

12 Jul '14

I was wondering where the symbol .test_main(int, char**) is defined if it comes up undefined. gcc.compile.c+ + ../bin.v2/libs/asio/test/basic_datagram_socket_select.test/gcc-4.8.1/debug/threading-multi/basic_datagram_socket.o gcc.link ../bin.v2/libs/asio/test/basic_datagram_socket_select.test/gcc-4.8.1/debug/threading-multi/basic_datagram_socket_select ld: 0711-224 WARNING: Duplicate symbol: .init_unit_test_suite(int, char**) ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information. ld: 0711-317 ERROR: Undefined symbol: .test_main(int, char**) collect2: error: ld returned 8 exit status I have done an object dump and I know it is undefined in libboost_test_exec_monitor.a, but that's as far as I got.
