Migrating svn.boost.org
by DongInn Kim 06 Jun '13

06 Jun '13

Hi, This time I would like to setup a schedule to migrate svn.boost.org to the new server (wowbagger.crest.iu.edu) This migration may need some downtime on the subversion, trac, and svnmanager services because we do not want to have any inconsistencies in SVN and or trac database. I have already rsynched the 1) boost SVN repository including its hook script, 2) trac db, and 3) SVNManager and its database. Do you have any hidden processes to manage the subversion repository, trac, or SVNManager? I implemented some simple testings with some SVN activities on the new server and it seems to work fine. Can anyone volunteer to play with the migrated SVN repository, trac, and SVNManager on the new server? I can test the very basic stuff and I may miss some functionalities of the current services. If anyone who actually work on the boost project can check this out, it would be much appreciated. I would feel much safer. 1. The downtime that we may have while migrating svn.boost.org I expect that TTL value be changed to 1hour or so. While the new DNS entries are populated, the current server will NOT service svn.boost.org and the new server will instead. - Date: Wednesday June 5th, 2013 - Time: 11:00am-12:00pm Pacific US time 12:00pm-1:00pm Mountain US time 1:00pm-2:00pm Central US time 2:00pm-3:00pm Eastern US time 6:00pm-7:00pm GMT 2. The unavailable services hosted on svn.boost.org : - Subversion - trac - SVNManager 3. The DNS entries to update: - Make svn.boost.org and wiki.boost.org point to 129.79.13.33 Please let me know if you have any questions or concerns about this migration. Regards, -- - DongInn

Re: [boost] [circular_buffer] New version of documentation
by Paul A. Bristow 06 Jun '13

> -----Original Message----- > From: Boost [mailto:boost-bounces@lists.boost.org] On Behalf Of Marshall Clow > Sent: Thursday, May 23, 2013 8:01 PM > To: boost(a)lists.boost.org > Subject: Re: [boost] [circular_buffer] Volunteer(s) needed After more work than I bargained for (see below for excuses) I have produced a Quickbook, Doxygen, Autoindex version from the existing documentation for Boost.Circular_Buffer at https://svn.boost.org/svn/boost/trunk/libs/circular_buffer/doc/circular_buf… I have made few substantive changes to the text, mainly adding more hyperlinks, (and correcting some that were wrong of missing - using the inspect tool is a really, really good idea!) So that users can comment on this new version, I have put html and pdf versions in my Dropbox. The pdf version is at https://dl.dropboxusercontent.com/u/43940943/circular_buffer.pdf which can of course be viewed by any PDF reader (I have recently moved to using Foxit instead of Adobe Reader). The html Quickbook version is from folder (libs/circular_buffer/doc/html) the at https://dl.dropboxusercontent.com/u/43940943/html/index.html (Sadly some of the icon .png files are inaccessible from the Dropbox version, which mars its beauty but you'll get the idea). This library uses the full automatic indexing of C++ names and hyperlinking to and from the text. The header files have the classes and functions fully documented in Doxygen format, and this is used to create the C++ reference sections: https://dl.dropboxusercontent.com/u/43940943/html/boost_circular_buffer_c__… to that you can see what the classes do and the parameters, template parameters, returns etc for the functions. I believe that these details are essential for Really Useful documentation. The original Doxygen standalone (whose format some users prefer) is at https://dl.dropboxusercontent.com/u/43940943/doxygen/html/index.html So you can see the pros and cons of the same information displayed side by side. The PDF and HTML versions also has an index at the end (this could be improved as it only gives C++ functions etc at present). Enjoy! (?) Comments welcome - praise preferred ;-) Paul PS Implementation notes: To get all the links correct proved *very* tiresome. Much of the trouble was inconsistent layout of existing documentation and files. IMO we need to use the GITMOD project to impose much more order on the file structure. I fear that the modularization changes will invalidate many links in documentation, so much revision will be needed :-( We must be able to predict where index.html etc will be to be able to write links without the current hassle. The Boost inspect tool proved invaluable, and all links are now reported correct. (Lots were wrong - in Doxygen comments in the header files, and in the Quickbook stuff :-( ) Despite this, there are still some sections in red where the html layout is wrong :-( I hope to find all of these in a later revision. --- Paul A.

In the light of C++11, the page on generic programming techniques http://www.boost.org/community/generic_programming.html is somewhat outdated. Any chance of a revision?

BOOST_STRONG_TYPEDEF
by Eric Niebler 05 Jun '13

05 Jun '13

Someone on stackoverflow is having a problem with BOOST_STRONG_TYPEDEF getting defined twice. There's a good recommendation there about boost/strong_typedef.hpp merely including boost/serialization/strong_typedef.hpp. Regardless, it's strange that trunk and release have been out of sync in this regard for so long.

[DNS] Heads up: svn.boost.org moving to a new server; IP address changing
by Beman Dawes 05 Jun '13

05 Jun '13

At 2:00 pm Eastern US time (i.e 30 minutes from now) we will switch svn.boost.org to a new server with a new IP address. It would be best to hold off on any SVN commits until after the change over, and after your DNS server has the new IP address. If command line "ping svn.boost.org" is going to [129.79.245.252], you are still getting the old IP address. Once svn.boost.org is resolving to [129.79.13.13] it should be OK to resume normal Subversion activity. Thanks, --Beman

[git] Library metadata
by Daniel James 04 Jun '13

04 Jun '13

Hello, Is anyone thinking about storing library metadata in modules? I'm thinking about this in context of the data required for the website, it'd be nice to automatically pull that from the library modules rather than having to maintain it myself, but I guess this might be something that others are thinking about (e.g. for the expected test failures, the library maintainer). So I was wondering if anyone has any plans? For anyone who isn't aware of it, the website data is stored in an xml file at: http://svn.boost.org/svn/boost/website/public_html/live/doc/libraries.xml Of course, it could be desirable to store modularized metadata in a different format.

[python] non-standard iteration / wrapping member function return value
by Matus Chochlik 04 Jun '13

04 Jun '13

Hi, I'm stuck at trying to make python bindings for a set of classes that use a non-c++-standard iteration protocol. I've made a minimal example of what I'm trying to do: the python-ized classes look in essence like this: //------------------------------------------------------------- class int_range { private: int i, max; public: int_range(int m) : i(0), max(m) { } bool empty(void) const { return i > max; } int front(void) const { return i; } void next(void) { ++i; } }; class range_maker { public: int_range make(void) const { return int_range(10); } }; //------------------------------------------------------------- the boost.python module that I've come up with so far: //------------------------------------------------------------- using namespace boost::python; class _py_int_range_iter { private: int_range _range; public: _py_int_range_iter(int_range range) : _range(range) { } _py_int_range_iter self(void) { return *this; } int next(void) { if(_range.empty()) objects::stop_iteration_error(); int result = _range.front(); _range.next(); return result; } }; class_<_py_int_range_iter>("_py_int_range_iter", init<const int_range&>()) .def("self", &_py_int_range_iter::self) .def("next", &_py_int_range_iter::next) ; class _py_int_range { private: int_range _range; public: _py_int_range(int_range range) : _range(range) { } _py_int_range_iter iter(void) { return _py_int_range_iter(_range); } }; class_<_py_int_range>("_py_int_range", init<const int_range&>()) .def("__iter__", &_py_int_range::iter) ; //------------------------------------------------------------- the problem is that when I register range_maker as follows... //------------------------------------------------------------- class_<range_maker>("range_maker") .def("make", &range_maker::make) ; //------------------------------------------------------------- ... it compiles but (obviously) fails in python at run-time because range_maker::make returns int_range and not _py_int_range. what do I need to do to make this work? I know that I could write _py_range_maker wrapping range_maker and let it return _py_int_range, but this approach does not scale very well. Is there some way to tell the def(...) function that I want to wrap the return value into an object of another type? Is there a return value policy for that or do I need to write my own? If so how? Thanks in advance Matus
