Hi John, just to confirm: your svn revision 43984 fixes my problem. Thanks for the fast response!

Confirmed: that looks like a valid use case to me! ;-) I hope this is now fixed in Trunk: note however, you can still generate types with type_with_alignment<> which can't be passed through a function by value - but only if no other "ordinary" type is available - previously type_with_alignment<> wouldn't have compiled in these cases anyway.

[Proto] Review
by David Abrahams 01 Apr '08

01 Apr '08

First, let me say that I enthusiastically vote for acceptance! - What is your evaluation of the design? Excellent. I would change some names here and there. - What is your evaluation of the implementation? I didn't look at the implementation much, but I am familiar with Eric's work and I have no doubt that it's stellar. - What is your evaluation of the documentation? A valiant effort, but still needs work. This is a difficult domain to explain, but I hope that Eric will keep trying :-) - What is your evaluation of the potential usefulness of the library? Extremely useful. I'm already looking forward to using it in at least two projects. - Did you try to use the library? With what compiler? Did you have any problems? I tried out a few of the early examples with G++ 4.1.3. The only problem I had is noted in the attached user guide walkthrough, and I very much doubt it was a compiler dependency. - How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? About 12 hours of careful reading through the user guide. - Are you knowledgeable about the problem domain? Reasonably knowledgeable. I have lots of experience with expression templates but very little with the domain of generalized ET libraries. The attached document contains many more comments. -- Dave Abrahams Boost Consulting http://boost-consulting.com

What has to be done to go live with the new web site? I assume this should happen as soon as the release packages go up on Sourceforge. Thanks, --Beman

[mp_math] a multi precision signed integer library
by Kevin Sopp 01 Apr '08

01 Apr '08

Hi all, I've been busy with porting the public domain C library libtommath to C++. The code is quite usable as it is and some simple documentation exists in the libs/mp_math/doc/html subfolder. I've implemented all C++ operators for the mp_int<> type and it can thus be used just like a built-in integer type. Some things like random number generation and primality testing have not been documented yet. Please have a look, I'm looking for feedback at the moment so that I can plan on how to proceed. http://www.boost-consulting.com/vault/index.php?action=downloadfile&filenam… alternatively go to boost vault /math - numerics subfolder and download mp_math_v01.zip Kevin

The user config file contains: using gcc : 4.2 : g++-4.2 : <define>_REENTRANT ; using python : 2.4 : /usr ; using python : 2.5 : /usr ; This always resulted in four static libraries and four shared libraries for, say, the date-time library. With 1.35, however, I get the four shared libs but only one static lib: steve@riemann{boost_1_35_0}grep 'gcc.link.dll.*date' ../boost_1.35.0-1_i386.build gcc.link.dll bin.v2/libs/date_time/build/gcc-4.2/release/libboost_date_time-gcc42-1_35.so.1.35.0 gcc.link.dll bin.v2/libs/date_time/build/gcc-4.2/release/threading-multi/libboost_date_time-gcc42-mt-1_35.so.1.35.0 gcc.link.dll bin.v2/libs/date_time/build/gcc-4.2/debug/libboost_date_time-gcc42-d-1_35.so.1.35.0 gcc.link.dll bin.v2/libs/date_time/build/gcc-4.2/debug/threading-multi/libboost_date_time-gcc42-mt-d-1_35.so.1.35.0 steve@riemann{boost_1_35_0}grep 'gcc.archive.*date' ../boost_1.35.0-1_i386.build gcc.archive ../../../bin.v2/libs/date_time/build/gcc-4.2/release/link-static/threading-multi/libboost_date_time-gcc42-mt-1_35.a How do I get all 8 library builds back?

[shifted_ptr] <T []> support, VC 8 certified, bug fix
by Phil Bouchard 01 Apr '08

01 Apr '08

Greetings: I got slowed down by a bug but fortunately I put my hands on it; - I fixed and updated the version in the Vault. - I have also made the headers compile fine under VC 8 but I haven't checked out the executable (missing objects). - I added safer support for array objects by limiting to access operator [] - I have replace "make_shifted_ptr" with "make_shifted_ptee" for efficiency reasons. It is possible to fall it back to its predecessor but requires some work, - I wanted to change the way sets are merge and did so. Todo: - Documentation. BTW I think Shifted Pointer got removed from the review schedule. I thought I didn't need documentation at that point but this is a short notice. Regards, -Phil

[gsoc 2008] JSON Archives for Boost.serialization
by Esteve Fernandez 01 Apr '08

01 Apr '08

Hi all, I'm new to this list but have been tracking Boost development for a long time. Never thought I could contribute something new to Boost, but after seeing this year's GSoC Boost proposal, I changed my mind and decided to take a deeper look at the JSON proposal. I've used the Boost.serialization library extensively and always end up needing something more portable than the binary archive and less heavyweight than the XML archive. Also, I spend a lot of time developing with Boost.Python and a format already supported by Python would be great, so seeing there was interest in a JSON archive was the perfect opportunity to join. Anyway, I've some points regarding this project before I apply, don't know if I should send them to Jeff (who suggested the idea) or to Robert (who implemented Boost.serialization). Instead of just bothering them, I'll bother all the subscribers to boost(a)lists.boost.org :-) - the JSON spec is quite simple, but given that it's a subset of YAML (actually Syck parses JSON as well), should it support it in the future as well? - what about Unicode? I know that Boost.Regex supports Unicode if compiled against ICU and the JSON spec states that everything must be in Unicode (correct me if I'm wrong) - TinyJSON and JSON.Spirit both use a MIT-like license (JSON.Spirit is licensed under CPOL). The Boost license is compatible with them but, could it pose a problem? There's JSONcpp [1] as well, which is public domain. - wading through the Boost mailing list archives, I found a message [2] by Daryle Walker in which he expressed interest in a JSON serializer some while ago (2005), but I think it wasn't discussed any further. Eric Newhuis wrote again about having a JSON archive just a few weeks ago [3] - which platforms must be supported? I can only provide support to GCC under Linux, but I guess it has to support MSVC and some other platforms. Will it have to be available for all the platforms supported by Boost at the end of the summer or is it more of a process? That is, given that one of the purposes of GSoC is to involve more people into free software/open source projects, whoever (I hope it's me :-)) implements the JSON serializer, will become its maintainer too and will take care of all the tasks related to accept patches, track bugs, add support for future/incomplete platforms, etc. - I thought of adding JSON support to Boost.Spirit as well. Currently it has support for printing ASTs in XML (see tree_to_xml). A JSON dumper would be quite useful for manipulating ASTs in a high level language, such as Python through Boost.Python Cheers. 1 - http://jsoncpp.sourceforge.net/ 2 - http://lists.boost.org/Archives/boost/2005/09/94438.php 3 - http://lists.boost.org/boost-users/2008/03/34336.php
