[githelp] Moving from push to pull requests
by Fletcher, John P 30 Apr '15

30 Apr '15

I have been working for some time on boost phoenix using git push origin develop to push my changes. I have now been asked to change to use pull requests and I am not clear about how to get into the new setup. My current setup on my local computer has phoenix as a subproject in a complete boost clone with branches develop, master and several other branches. I have not created any branches on the remote repository. What I want is to have a repository where I can work and then send pull requests for things to go to the main develop. I have two ideas about how this could be done. (1) create a separate repository outside the modular structure and put a copy of phoenix there. I have created an empty structure called phoenix_changes both on my local computer and under my user name on github. I am puzzled as to how to get the correct content into it. This could come from my local copy or from the main repository. (2) Should I instead create a new branch in both my local and the remote copies of boost/phoenix? If so how do I do that? Can I branch from the current develop as the starting point? In either case I want to be able to send pull requests to the other developers. It would be helpful to have an example of the commands needed. Please ask me for more information if this is not clear. Thank you for the [githelp] resource. John

[Boost] Windows 10 Building/Testing
by Kyle Ketterer 30 Apr '15

30 Apr '15

Hey all, I was just curious if any devs/users have tried to compile/build on any of the Windows 10 preview releases and if there is a plan to support moving forward. I have been using Boost in various projects for 4-5 years and I am actually interested in getting involved in this project somehow. What is the most appropriate way to become involved? I really appreciate the skill level here and if anything would love the learning experience (learning from the best). Thanks

Updated library_status for easier use..
by Rene Rivera 29 Apr '15

29 Apr '15

Following up on the reorganization of the regression tools.. I'm happy to say that part of the changes I pushed last night include a cleaned up and easier to use library_status tool. Key changes, from the older version and the one Robert forked, are: * Processing the jam log (i.e. process_jam_log) is integrated into it. * Running b2 to build/run tests is also integrated into it (optionally). Which means that there's no external support script(s) needed and that it's fully cross-platform single executable. Documentation is updated at < https://rawgit.com/boostorg/regression/develop/index.html> on how to build it and on using it at < https://rawgit.com/boostorg/regression/develop/library_status/doc/library_s… >. Obviously improvements from others welcome (as PRs).

It is recommended that you notify your local Trac administrator with the information needed to reproduce the issue. To that end, you could a ticket. The action that triggered the error was: GET: /login"

by Fu ji 28 Apr '15

28 Apr '15

Hello all, I have file output.txt, in file we can find something like: 01/01/2015 15:00:00 2222.2222 2222.2222 2222.2222 2222.2222 04/04/2015 15:00:00 2222.2222 and i would like to change format from DD/MM/RRRR HH:MM:SS to RRRR-MM-DD HH:MM:SS.000 using boost regex. But I have no clue how should I type pattern and replace them with another. Anyone have knowledge about boost regex and could help me ? Best regards

[date_time] Ordering non-overlapping time period
by Arindam Mukherjee 28 Apr '15

28 Apr '15

The documentation for time_period suggests that for two periods tp1 and tp2, tp1 < tp2 if tp1.end() < tp2.begin() i.e. !tp1.intersects(tp2). http://www.boost.org/doc/libs/1_58_0/doc/html/date_time/posix_time.html#dat… But I can see that the following works: time_period tp1(second_clock:local_time(), hours(2)); time_period tp2(second_clock:local_time() + hours(1), hours(2)); assert(tp1.intersects(tp2)); assert(tp1 < tp2); The behavior seems legit - tp1.begin() < tp2.begin()/ The documentation says nothing about overlapping periods.

[test] floating point comparison
by Emil Dotchevski 28 Apr '15

28 Apr '15

Hello, Can someone please tell me exactly what do I need to include and which namespace to use to get exact same behavior as: #include <boost/test/floating_point_comparison.hpp> bool check( float a, float b, float tolerance ) { using namespace boost::test_tools; return check_is_close(a,b,fraction_tolerance(tolerance)); } (The above used to work with older Boost versions but no longer.) Thanks, Emil

[boost, config, context, log, 1.58] address-model and architecture detection
by Vladimir Prus 28 Apr '15

28 Apr '15

Hi, for some time on develop, top-level Jamroot used to deduce address-model and architecture from compiler. The only issue was that both properties would be added to targets paths when not necessary. Fix for that has been just committed, for develop: https://github.com/boostorg/boost/commit/945e3c0bbdd31ce8c297e0aff5340f0adb… and I performed these operations on master: - Merged all of Boost.Build changes: https://github.com/boostorg/build/commit/2e764707e03d25b6928501c25a717e195c… - Cherry-picked one Boost.Context change: https://github.com/boostorg/context/commit/9b392c68b59021aa4801dcb245bc64ad… - Cherry-picked one Boost.Log change: https://github.com/boostorg/log/commit/27a822a6b82f8bf34cbc681ac6583412bdf2… - Cherry-picked two root project changes and updated pointers to Context and Log: https://github.com/boostorg/boost/commit/e3bc35f7891e72ad74e57dc216db899d16… https://github.com/boostorg/boost/commit/beb53b6b9574f95309384bfc5afffb40d4… https://github.com/boostorg/boost/commit/b69a072401695c9978085158af4c1ea84c… With that, "./b2 -n" in up-to-date checkout of superproject works fine on Linux. Also, "./b2 -n --with-context --with-system" works fine, no address-model elements in path. Putting explicit address-model=64 does not change path. Putting explicit address-model=32 does add this element to path, as expected. Note that: - I did not merge any other Boost.Context or Boost.Log changes. - Nothing was required for Boost.Config, since it was merged earlier. I'd appreciate if people test current state of master branch, and report any concerns. Thanks, -- Vladimir Prus CodeSourcery / Mentor Embedded http://vladimirprus.com

[afio] Compilation error in applications, including tests
by Brian Ravnsgaard Riis 27 Apr '15

27 Apr '15

Hi, I wanted to try out the proposed AFIO library, but I'm having trouble with compilation. I followed the instructions for inserting it into the boost checkout, by symlinking libs/afio to the AFIO checkout. Boost compilation happens correctly, including the AFIO library, however I get include failures on BindLib when I try to compile a test program. I then tried running the test suite, as per instructions: $ ./b2 libs/afio/test [snip] gcc.compile.c++.pch bin.v2/libs/afio/test/gcc-4.9.1/debug/threading-multi/test_functions.hpp.gch In file included from ./boost/afio/spinlock/include/boost/spinlock/concurrent_unordered_map.hpp:35:0, from ./boost/afio/config.hpp:341, from ./boost/afio/afio.hpp:41, from libs/afio/test/test_functions.hpp:17: ./boost/afio/spinlock/include/boost/spinlock/spinlock.hpp:81:36: fatal error: bindlib/include/import.h: No such file or directory #include "bindlib/include/import.h" ^ compilation terminated. ... And more of the same ilk. Am I missing some obvious configuration or something? The boost version is at tag boost-1.58.0 and AFIO is at tag v1.31_Boost_v1.58. The BindLib submodule does contain include/import.h. Regards, Brian
