by Beman Dawes 03 Dec '13

03 Dec '13

If I do this: git clone --recursive git@github.com:boostorg/boost.git modular-boost cd modular-boost/libs/math git checkout develop What commit of math develop branch should be checked out? The current head? The head at the time of the git clone? Some other head? --Beman

[ANN] C++Now 2014: 5 Days to Submissions Deadline
by Boris Kolpackov 03 Dec '13

03 Dec '13

Hi, Only 5 days left before the submissions deadline for C++Now 2014! C++Now is a general C++ conference for C++ experts and enthusiasts. It is not specific to any library/framework or compiler vendor and has three tracks with presentations ranging from hands-on, practical tutorials to advanced C++ design and development techniques. For more information about C++Now, see the conference's website: http://cppnow.org/about/ Have you learned something interesting about C++ (e.g., a new technique possible in C++11)? Or maybe you have implemented something cool related to C++ (e.g., a C++ library)? If so, consider sharing it with other C++ enthusiasts by giving a talk at C++Now 2014. For more information on possible topics, formats, etc., see the call for submissions: http://cppnow.org/2013/10/21/2014-call-for-submissions/ Boris

[conversion] GitHub boostorg repos now open for regular use
by Beman Dawes 02 Dec '13

02 Dec '13

Please be cautious at first, and report any problems. It is probably a bit surer to follow the full clone instructions at https://svn.boost.org/trac/boost/wiki/TryModBoost rather than trying to make use of a previous clone. Also note that those instructions have been corrected several times, the most recent correction just a minute ago. We will be setting up write permissions, but that may take a day or so. Thanks, --Beman

[conversion] Progress Report
by Beman Dawes 02 Dec '13

02 Dec '13

We are very close to being able to go live with boostorg at GitHub. * Following the instructions at https://svn.boost.org/trac/boost/wiki/TryModBoost, the "master" branch seems ready to go. * A couple of libraries on the "develop" branch may still have end-of-line issues. If so, those should be resolved first thing in the morning. So please be patient one more day, and then we should be able to get to work using git and modular boost. --Beman

circular buffer patch
by Serge A. 02 Dec '13

02 Dec '13

It appears that the circular_buffer no longer has a maintainer. I have a patch that fixes a problem introduced in the latest versions of the circular buffer that it can not correctly work with a custom memory allocator. The patch is provided here: https://svn.boost.org/trac/boost/ticket/9334 The former maintainer suggested to submit a request to this list, so that the patch is included in the daily build and the next release. Thanks! Serge

[COUNTERTREE + SUBALLOCATORS] Errors corrected, .New Lock system, manycore strategies
by Francisco José Tapia 02 Dec '13

02 Dec '13

I have corrected several errors ( thanks to the people who sent me comment, suggestions and bugs). The lock mechanism ( 1 Writer / N Readers) have been redesigned in order to correct previous errors and increment the speed. The actual version is built over spinlocks and yield functions. It provide an alternative to the upgrade mutex. You have a detailed description with diagrams and examples in https://dl.dropboxusercontent.com/u/8437476/works/countertree_2.0/doc/singl… *LIBRARY DESCRIPTION* This library provide a concurrent and thread safe implementation of the *tree based data structures* (set, multiset, map and multimap, plus a unordered tree named vector_tree) with *random access iterators* and *access by position like a vector*. This permit to *distribute the elements* stored in the trees, between an *arbitrary number of threads*, identically as do with the vectors. Over it you can use many algorithms designed for vectors ( as quicksort over an unsorted tree) and *making easy the design of parallel algorithms* applied to the tree based data structures , and their use by the multicore development tools.. [image: Imágenes integradas 1] These data structures are based on a kind of augmented red-black trees, where each node have a counter with with the number of nodes under which permit the access by position, like in a vector, to the elements stored in the tree, and random access iterators. I named this tree of counters *countertree* Until now, in many practical problems, the binary trees was not used , by the difficult for to distribute the elements stored between an arbitrary number of cores, and the difficult for to develop parallel algorithms. This limitation force to use only 1 thread with these data structures. And with big problems, usually it is not a good solution. With the countertrees, perhaps it would be interested reevaluate some algorithms, and make an comparison between the present algorithms and the possible options, in order to see the performance, the memory used and the flexibility. If you are interested, you have a brief document ( 2 pages) about the manycore strategies<https://dl.dropboxusercontent.com/u/8437476/works/doc/Manycore_Strategies.p…>with this library, and other brief project description<https://dl.dropboxusercontent.com/u/8437476/works/doc/Brief_project_descrip…>(2 pages) where provide a global vision of the project and their parts. I think is a good starting point in order to examine the library. *You can find the code and the documentation in my web pages in dropbox* *https://dl.dropboxusercontent.com/u/8437476/works/countertree_2.0/index.html <https://dl.dropboxusercontent.com/u/8437476/works/countertree_2.0/index.html>* *or if you prefer in a git format* *https://github.com/fjtapia/countertree_2.0 <https://github.com/fjtapia/countertree_2.0>* Please, if you have any idea , any comment or see any fail, any lack, please say me in order to improve the library, and provide between all ,a fast, robust and reliable tool to the C++ programmers. If you want more information, need something, please, say me, and I will try to do. Thanks by your interest. Yours Francisco Jose Tapia e-mail : fjtapia(a)gmail.com

Subversion repository closed for all commits on all branches
by Beman Dawes 02 Dec '13

02 Dec '13

The Subversion repository is now closed for all commits on all branches. An attempt to commit will fail a pre-commit hook, resulting in the following error message: Command: Commit Modified: C:\boost\trunk\libs\system\doc\index.html Sending content: C:\boost\trunk\libs\system\doc\index.html Error: Commit failed (details follow): Error: Commit blocked by pre-commit hook (exit code 1) with output: Error: This Subversion repository is no longer in active use. Error: Error: It has been superseded by a Git super-project repository Error: and individual Git repositories for each Boost library. Error: Error: See: https://github.com/boostorg Completed!: The next step in the conversion to Git and Modular Boost is to run the conversion script one last time, and then turn it off. We will let you know when that is completed. -- The Release Managers

[git-help][eclipse] Fetching the full repo?
by Rene Rivera 02 Dec '13

02 Dec '13

First, I'm asking about using git from within Eclipse since that's where I do everything.. I've had a Boost master clone for a long time now. And having a very small amount of time I decided to start updating and looking at the latest state of the repo. Unfortunately everything I attempt to get my local checkout to match the head state of the repo is failing. In particular the subrepos are not being fetched or refreshed. And some of the subrepos are missing and hence show up as pending delete changes. Does anyone know how to get the Eclipse git to fetch/reset to the head fully?
