missing checks of compilation flags in boost/detail/container_fwd.hpp
by F.S. 26 May '10

26 May '10

Hello everybody, I don't how to send patches to you. This is a very small one, which allows to compile boost libraries with gnu c++ library using the Profile or Parallel mode. Maybe it's useful for you: *************** *** 13,19 **** #include <boost/config.hpp> #include <boost/detail/workaround.hpp> ! #if ((defined(__GLIBCPP__) || defined(__GLIBCXX__)) && ( defined(_GLIBCXX_DEBUG) || defined(_GLIBCXX_PROFILE) || defined(_GLIBCXX_PARALLEL))) \ || BOOST_WORKAROUND(__BORLANDC__, > 0x551) \ || BOOST_WORKAROUND(__DMC__, BOOST_TESTED_AT(0x842)) \ || (defined(__SGI_STL_PORT) || defined(_STLPORT_VERSION)) --- 13,19 ---- #include <boost/config.hpp> #include <boost/detail/workaround.hpp> ! #if ((defined(__GLIBCPP__) || defined(__GLIBCXX__)) && defined(_GLIBCXX_DEBUG)) \ || BOOST_WORKAROUND(__BORLANDC__, > 0x551) \ || BOOST_WORKAROUND(__DMC__, BOOST_TESTED_AT(0x842)) \ || (defined(__SGI_STL_PORT) || defined(_STLPORT_VERSION)) Regards Florian

[serialization] Warnings from spirit header in XML archive headers (non_terminal/rule.hpp)
by Number Cruncher 26 May '10

26 May '10

I'm encountering many warning about a deprecated header when writing my own XML input archive class: In file included from /opt/cfs/include/boost/archive/impl/basic_xml_grammar.hpp:59, from /opt/cfs/include/boost/archive/impl/xml_iarchive_impl.ipp:41, /opt/cfs/include/boost/spirit/core/non_terminal/rule.hpp:18:4: warning: #warning is a GCC extension /opt/cfs/include/boost/spirit/core/non_terminal/rule.hpp:18:4: warning: #warning "This header is deprecated. Please use: boost/spirit/include/classic_rule.hpp" This is because the serialization library is using "Spirit.Classic" and should be including different headers: http://www.boost.org/doc/libs/1_43_0/libs/spirit/doc/html/spirit/what_s_new… I've noticed patches related to this on the web, e.g. http://gitorious.org/ryppl/doc/commit/2711cc4a1e8751455f9188ffefa9b34de1379… ... and have repackaged a patch against the current 1.43.0 which fixes these warnings? Please could this be committed for the next release? Regards, Simon

[MSM] compiling MSM with GCC 4.4.1 and -fno-exception
by Richard Szabo 26 May '10

26 May '10

Hi Christophe Thanks for the fix of no-rtti I will try out shortly. I have discovered a similar issue with exceptions. GCC 4.4.1 reports errors when it parses MSM that exceptions are disabled but there is code using that. Thanks Richie

[thread] r62122 fix for #3178 introduces duplicate symbol
by Lars Viklund 26 May '10

26 May '10

Hi list. In trunk, revision 62122 (which fixes a negative sleeping time bug #3178) added a detail helper function pin_to_zero at boost/thread/win32/thread_data.hpp:148, which isn't marked inline. This leads to multiple symbol definitions for anything that tries to link to Boost.Thread. The fix is trivial, just add an inline. -- Lars Viklund | zao(a)acc.umu.se

CGI / FastCGI library update
by Darren Garvey 26 May '10

26 May '10

Hi, I have packaged a version of a CGI / FastCGI library* up to sourceforge and would very much appreciate feedback and critique from interested parties. Feedback from this list has been invaluable in the past. You can download the library from: http://sf.net/projects/cgi/files The documentation still needs work, which I am doing as I can find the time. It can be found online at: http://cgi.sf.net/docs and a brief feature list can be found from: http://cgi.sf.net The library interface has reached a relatively stable point after a savage bunch of changes recently and I'm quite pleased with how it is shaping up. A brief list of features of the library are: * Out of the box support for FastCGI and CGI, tested with Apache 2.2 and mod_fcgid on Windows XP, 7 and linux. * Type-safe access to different request data (eg. get / post / environment / cookies) * Access to request data in STL-like constructs, with some CGI-specific helper functions. * Optional support for user-defined, strongly-typed sessions. * A lightweight utility wrapper for using HTML / XML / etc. templates - dubbed "stencils". * A traits-based design that allows library users to alter the implementation of parts of the library at compile time. For reference, the code is also in the Boost sandbox at: https://svn.boost.org/svn/boost/sandbox/SOC/2007/cgi/trunk Cheers, Darren * the one started way back in the GSoC of 2007...

[log] Forward Declarations
by Christoph Heindl 26 May '10

26 May '10

Andrey, are you thinking about providing a header containing forward declarations of boost.log datatypes? If not, I'd like to request that feature. Best regards, Christoph

[fusion] type in doc
by vicente.botet 26 May '10

26 May '10

Hi, I guess there is a typo in fusion/extension/sequence_facade.html " The sequence_facade template provides an intrusive mechanism for producing a conforming Fusion iterator. " Instead of iterator should be sequence, isn't it? _____________________ Vicente Juan Botet Escribá http://viboes.blogspot.com/

The switch is actually pretty cool and made my life way easier :) Richard, I just committed the fix in the trunk (https://svn.boost.org/svn/boost/trunk/boost/msm/back/state_machine.hpp) it should work now. Thanks, Christophe

[serialization] Binary iarchive invalid signature
by Gevorg Voskanyan 25 May '10

25 May '10

Hi, Binary iarchive is supposed to throw invalid_signature archive_exception when the archive content doesn't start with the expected signature. However in some cases a different behavior is observed when trying to load from an invalid archive. For example, if the supposed signature size being read ends up a huge number (can easily happen trying to load from an arbitrary file not created with Boost.Serialization), the program spends a few seconds on line 111 of basic_binary_iprimitive.ipp (s.resize(l);) allocating a big chunk of memory to read the signature into, then tries to read that many bytes from the stream, which, assuming the file is not that large, reads less bytes than requested so it all ends up throwing archive_exception(stream_error) at basic_binary_iprimitive.hpp:164. Another example is when the 'signature size' being read happens to be a larger number still, then s.resize(l); throws std::bad_alloc when in fact the user would want to get archive_exception(invalid_signature) instead. I've attached a patch for archive/impl/basic_binary_iarchive.ipp against Boost 1.43 version that fixes the problem for me. Comments? Thanks, Gevorg P.S. Boost 1.43, Win XP SP2, MSVC 8
