[gsoc15] Proposal
by Ganesh Prasad 12 Feb '15

12 Feb '15

Now that we are rather well ahead with the phoenix library, I propose to develop a compile-time Logic Programming library for boost. I understand that a handful of months during GSoC15 are not enough for developing a complete and usable library, but the foundations of the library can be laid during this GSoC. I have some experience with writing a small compile-time library for functional programming with a LISP like syntax. That can be found at https://github.com/GnsP/GNS--META_LISCPP . Currently I am trying to identify the requirements for a decent compile-time logic library. If it could be acceptable as a GSoC project (I don't know, the idea is pretty big one for 3 months), I'll be back with an initial design of the proposed library. Best Wishes Ganesh Prasad PS I had been planning on this library since last year, I am positive that this project is feasible (though Logic programming would require non-determinism, it can be handled to some extent with template metaprogramming, I'm still working on it).

GitHub third-party application permissions
by Vladimir Prus 11 Feb '15

11 Feb '15

Hi, the GitHub boostorg organization is configured in a way that any application authorized by any organization member will have full access to boostorg data. Is that desirable? I've noticed accidentally, and don't know much about github permission model, but it seems that all authorized applications will have access to all repositories the user has, there does not appear a way to limit either repositories or operations.

Cleanup of test results.
by Rene Rivera 11 Feb '15

11 Feb '15

Just an FYI for testers and authors.. I implemented some changes to the report generation that: a) Expires old results to not be shown in the results. I'm considering old to be anything past two weeks of age. This applies to all branches (i.e. develop and master). b) Filtering of master, aka release, results to only include an approved list of testers. This brings in some explicit control to what is considered the release toolsets. Which is something we used to enforce, but lost after the git transition. So it's back now.

Hi Andrii, I'm implementing a Lloyd's algorithm to get a centroidal Voronoi tessellation of a box. In this algorithm, I need to get the voronoi cells in the box, and find the centroids of these cells. Thanks,Dan

[gsoc15] Google Summer of Code 2015 ideas needed before 20th Feb
by Niall Douglas 09 Feb '15

09 Feb '15

Dear Boost community, The Google Summer of Code 2015 organisation application period has begun. We need project ideas for our ideas page at https://svn.boost.org/trac/boost/wiki/SoC2015, plus anyone willing to mentor. Last year we got eight slots, the previous year seven slots. Let's try to get back to ten slots for 2015! Niall & Boris --- Boost C++ Libraries Google Summer of Code 2015 admin https://svn.boost.org/trac/boost/wiki/SoC2015

Regression testing: too many runners?
by Dmitry Moskalchuk 09 Feb '15

09 Feb '15

Guys, As you may know, I'm working on automatic regression testing of Boost on Android. I spent several weeks debugging it and now it seems to be close to the finish - i.e. we'll have soon fully automatic 24x7 regression testing with uploading all results to the Boost public FTP. As you can see, some results are already uploading on a regular basis - http://www.boost.org/development/tests/master/developer/summary.html (there are results of just few libraries at the current moment since I've limited testing by only those libraries to save time needed for debugging testing scripts; as far as I finish with my debugging, I'll enable testing of all libraries). However, I've realized that for thorough testing matrix of the variants become really big. Look, right now there are nine runners for Android, and this number is in fact very limited. They differs by target ABI (three arm variants, x86 and x86_64) and version of Android (API level 19 - Android 4.4 and 21 - Android 5.0). However, it has sense to test also on Android 4.0, 4.1, 4.2 and 4.3 since theirs market share is still large (see https://developer.android.com/about/dashboards/index.html) Add to that MIPS target ABI (not yet included to the testing) and multiple by two to have tests running with both default settings and with -std=c++11 - and you'll get really big total number of runners. I'm asking for advice from community. It's not the big problem for us to run all such tests in all variants, but I'm unsure if it will be acceptable for Boost community to see such wide table of runners. I'm afraid it will look like a flood. We also publish Android-only results on https://boost.crystax.net/master/developer/summary.html and we'll definitely display all results from all runners there. Please let me know if the same approach would work for http://www.boost.org/development/tests/master/developer/summary.html or should I limit somehow runners to be uploaded to the Boost FTP. -- Dmitry Moskalchuk

[githelp] Relative submodule paths..
by Rene Rivera 09 Feb '15

09 Feb '15

I've been trying to clean out the pull requests for the boost super-project and I ran into this one <https://github.com/boostorg/boost/pull/33>. And I don't really know if it makes sense, as I have personally not done a fork of the super-project. Is it a real problem? Should we change all the sub-project references? If yes, what are the likely impacts on others and existing release processes? -- -- Rene Rivera -- Grafik - Don't Assume Anything -- Robot Dreams - http://robot-dreams.net -- rrivera/acm.org (msn) - grafikrobot/aim,yahoo,skype,efnet,gmail

[polygon] voronoi diagram in a bounding box
by Dan Chen 08 Feb '15

08 Feb '15

Hi all, I am not sure whether this is the right place to ask this question. Basically, I want to compute the the voronoi diagram of a set of points in a bounding box, and output the voronoi cells. My idea is, after getting the voronoi diagram vd of the point set, for each voronoi cell in vd, compute the intersection of the cell and the bounding box. I am wondering whether this can be done in a better way with the boost libraries. Thanks,Dan
