Git permissions model
by Vladimir Prus 09 Dec '13

09 Dec '13

Hi, I have a couple of questions about the permission models that we use for git. - To give somebody push access to the 'build' repository, I need to file an admin issue. Why can't I control access to the repository I maintain? In fact, why I can't even edit repository description? - Suppose I find a random typo in library X. In SVN, I can just fix it within a minute. In Git, I would have to either ask for push access (which I think won't scale), or I need to fork the repo, to the change, and submit a pull request, which is equally cumbersome. Was not Git supposed to simplify things? Thanks, Volodya

Ping - this still needs to be fixed. In the New World Order, https://github.com/boostorg/concept_check/commit/168e60a needs to be merged from develop to master. Thanks, STL

C++Now 2014: Call for Submissions, Updated deadlines
by Hartmut Kaiser 09 Dec '13

09 Dec '13

Updated submission dates! Please see below! ============================================== C++ Now Conference 2014 Aspen CO, USA, May 12-17, 2014, www.cppnow.org ============================================== For the full announcement online, please see here: http://cppnow.org/2013/10/21/2014-call-for-submissions/ Call for Submissions -------------------- We invite you to submit session proposals to the 3rd annual C++Now Conference (Aspen CO, USA, May 12-17, 2014). Building upon the resounding success of C++Now 2013 and five years of BoostCon, C++Now 2014 will present leading speakers from the whole C++ community. The C++Now Conference is dedicated to discussion and education about C++, an open and free language and standard. Our Conference will focus on discussion and education about open source software usage and developments in the C++ developer and user community. To reflect the breadth of the C++ and Boost communities, the conference includes sessions aimed at three constituencies: C++ and Boost end-users, hard-core Boost library and tool developers, and researchers pushing the boundaries of computation. The program fosters interaction and engagement within and across those groups, with an emphasis on hands-on, participatory sessions. As a multi-paradigm language, C++ is a melting pot where the most compelling ideas from other programming communities are blended in powerful ways. Historically, some of the most popular sessions at C++Now have highlighted these concepts, from DSLs to functional programming to transactional memory and more. Bring your C#, Python, Ruby or Haskell influences to bear in an environment that will broaden their exposure. At C++Now 2014 we would like to focus on the now established C++11 standard and the new, upcoming C++14 and how those standards are and will shape C++'s future. However, by no means is this intended to restrict the topics of proposals we hope to see. Any other topic related to C++ as outlined below is perfectly fine for submission. Important dates --------------- New proposal submissions due: December 22th, 2013. Proposals decisions sent (tentative program available): February 15th, 2014. Fully scheduled program available: February 28th, 2014. Best Presentation Awards ------------------------ We know how much effort it takes to prepare talks for our conference. For this reason we will award the best The awards will be given based on the audience's voting. Each award will include the author's name listed on the cover of the C++Now website for that year and a plaque containing all the C++Now conference information. Session topics -------------- Topics of interest include, but are not restricted to, the following: * C++11/14 and how it changes life for users and library writers * General tutorial sessions on C++11/14, the C++11/14 Standards library, and one or more Boost libraries * Parallelism in the new C++11/14 standard * Parallel, distributed and GPGPU topics relating to C++ * In-depth sessions on using specific Boost libraries * Case studies on using Boost * Experts panels * Advanced sessions on implementation techniques used within Boost libraries * Development workshops to extend or enhance existing Boost libraries * Workshops on design process * Infrastructure workshops such as Build tools, Website, Testing * Concepts and Generic Programming * Hardware and infrastructure presentations focused on how libraries can make better use of the technology * Software development tools and their application to C++ and or Boost * Other topics likely to be of great interest to C++ users and developers Interactive and collaborative sessions are encouraged, as this is the style of learning and participation that has proven most successful at such events. Sessions can be tutorial based, with an emphasis on interaction and participant involvement, or workshop based, whether hands-on programming or paper-based, discussion-driven collaborative work. Session formats --------------- Presentations Presentations focus on a practitioner's ideas and experience with anything relevant to C++11 or C++14, Boost and users. Panels Panels feature three or four people presenting their ideas and experiences relating to C++11 or C++14 and Boost's relevant, controversial, emerging, or unresolved issues. Panels may be conducted in several ways, such as comparative, analytic, or historic. Tutorials Tutorials are sessions at which instructors teach conference participants specific skills relevant to C++11 or C++14 and Boost. Workshops Workshops provide an active arena for advancements in Boost-relevant topics. Workshops provide the opportunity for experienced practitioners to develop new ideas about a topic of common interest and experience. Author's Corner Presentations These were introduced at BoostCon 2008, and were a great success. They are short (30 minute) sessions, focusing on tips on usage and design. In addition, we're looking to uncover the hidden design gems in Boost libraries. Tool Vendors Presentations We actively encourage tool vendors and ISP's to submit proposals for a special Tool Vendors Session Track aimed at products related to Boost and C++ (compilers, libraries, tools, etc.). Other formats may also be of interest. Don't hold back a proposal just because it doesn't fit into a pigeonhole. Submitting a proposal --------------------- Standard sessions are 90 minutes. You may submit a proposal for fractions or multiples of 90-minutes. Fractional proposals will be grouped into 90 minute sessions covering related topics. Longer sessions, such as tutorials and classes, will be assigned three hour (i.e. half day), or six hour (i.e. full day) time slots. Please include: * The working title. * Type of session: presentation, panel, tutorial, workshop, authors corner, vendor track, other. * A paragraph or two describing the topic covered, suitable for the conference web site. * Proposed length: 10-20 minute short talks, 45 minutes, 90 minutes, half day, full day. * Alternate lengths, if you are willing to make adjustments: 10-20 minute short-talks, 45 minutes, 90 minutes, half-day, full day. * Audience: users, developers, both. * Level: basic, intermediate, advanced. * A biography, suitable for the conference web site. * A photo of about 150 x 150 * Your public contact information (twitter handle, blog, website, google plus, etc.) * Your contact information (will not be made public). Submission details ------------------ All submissions should be made through the EasyChair conference management system: http://www.easychair.org/conferences/?conf=cppnow2014. If you have not already registered at EasyChair, you will need to do so in order to submit your proposal. All submissions will go through a peer review process. Authors are invited (but are not required) to submit PDF versions of full papers of up to 10 pages in ACM conference proceedings format (see http://www.acm.org/sigs/publications/proceedings-templates) The full papers are not required unless you want them published in the proceedings. All accepted proposals will be made available in the Association for Computing Machinery (ACM) Digital Library (approval pending). Best papers, after further reviews, will be considered to be book chapters or journal articles in a renowned journal. The session materials go on the C++ Now website and will be available to attendees.

[git] Are we free to delete old branches?
by John Maddock 09 Dec '13

09 Dec '13

I notice most of my stuff is littered with old branches, most of which have nothing to do with the library in question (or are even related to old CVS branches). Are we free to delete these old branches without effecting any other lib? Is it a good/bad idea? Seems to be recommended practice in Git to delete branches once they're no longer needed? Thanks, John.

[concept_check] Merge changes to master
by Daniel James 09 Dec '13

09 Dec '13

Hi, I merged some old changes to master, all warning fixes, all old enough to be fully tested on trunk: https://github.com/boostorg/concept_check/commit/229e3055a03210da4dd10d43bc… https://github.com/boostorg/concept_check/commit/ccd9f52467953f4b569f52cb6a… https://github.com/boostorg/concept_check/commit/9521991561bf574772ce48d38c… https://github.com/boostorg/concept_check/commit/168e60aa3d5238cd25b341661a… I cherry picked the first two because they're a bit old. It's a bit late now, but do you think I should have done this as a pull request? Daniel

[git] Update submodules in boost.git
by Daniel James 09 Dec '13

09 Dec '13

Hi, I've just updated all the submodules in the main git repo. I'll try and do this daily for a little while, but we'll need to automate it. Preferably triggered by a hook so it's as close to instantaneous as possible. Any takers? Daniel

[git] develop and master are two completely distinct branches
by Thomas Heller 08 Dec '13

08 Dec '13

Hi, I just cloned modular boost and wanted to get phoenix back on track. However, something very disturbing occured to me: The develop and master branches in the git repos (for all repos) are completely distinct from each other! How could this happen? In the case of phoenix those have, unfortunately, completely diverged from each other (content wise, commit wise, they have completely distinct commits). What's the best practice to do here? How to proceed? Regards, Thomas P.S.: Sorry for the long absence

[git] Mess with branches
by Antony Polukhin 08 Dec '13

08 Dec '13

What's the current policy about merging and removing branches in libraries? Can I for example merge and remove old svn-branches/filesystemv3 in module boost/conversion or will it break some functionality? -- Best regards, Antony Polukhin

Pull request sanitise run on Travis CI (Re: [git] Near future.. How do we deal with git-native libraries?)

GitHub pull requests (PR) are nicely handled by Travis CI service (https://travis-ci.org/‎) Perhaps, it would make sense to set up Travis for Boost repositories as well. Then, for every PR submitted to one of Boost repos, a Travis build is performed and PR sanitisation script could be part of that build. A nice feature of GitHub+Travis integration is that GitHub PR ticked will automatically display status of corresponding Travis build, warning about broken that particular PR is broken, so merge with caution, etc. Best regards, -- Mateusz Łoskot, http://mateusz.loskot.net

[git] Problems with Boost.Sync
by Andrey Semashev 07 Dec '13

07 Dec '13

Hi, My first experience with git is failing miserably. I was trying to checkout Boost.Sync, which is not present in the normal checkout as described in the wiki [1]. It is only present in the develop branch, so I thought I have to do: git submodule foreach --recursive git checkout develop That didn't help, so I also did git checkout develop git pull The last command failed with the error: First, rewinding head to replay your work on top of it... Applying: Fixed serialization of the wave tool. Using index info to reconstruct a base tree... M libs/wave Falling back to patching base and 3-way merge... warning: Failed to merge submodule libs/wave (commits don't follow merge-base) Auto-merging libs/wave CONFLICT (submodule): Merge conflict in libs/wave Failed to merge in the changes. Patch failed at 0001 Fixed serialization of the wave tool. The copy of the patch that failed is found in: /home/lastique/src/boost/.git/rebase-apply/patch When you have resolved this problem, run "git rebase --continue". If you prefer to skip this patch, run "git rebase --skip" instead. To check out the original branch and stop rebasing, run "git rebase --abort". I swear I didn't even touch wave! The mentioned patch is: b17f63d8d907c50d3a91e064c62ec47bfcc38050 diff --git a/libs/wave b/libs/wave index 55350dd2f9d1ce39aa253c49e9e10f073f776a35..96207efc61d549b9a810f067bfefe2bf55c28a65 160000 --- a/libs/wave +++ b/libs/wave @@ -1 +1 @@ -Subproject commit 55350dd2f9d1ce39aa253c49e9e10f073f776a35 +Subproject commit 96207efc61d549b9a810f067bfefe2bf55c28a65 This looks like a superproject metadata for the submodule, and I have no idea to what I should apply this patch. I'm at a loss. 1. How can I get rid of this error? 2. How can I checkout Boost.Sync?
