It seems like some source files included in Jamfile are not included in Jamfile.v2 in the serialization library. thanks -- Arvid Norberg

bizarre test results: foreach, gcc-4_0-darwin
by Eric Niebler 01 Sep '05

01 Sep '05

I need help understanding some of the recent regression results. At http://tinyurl.com/72q3k you can see the most recent Foreach test results. The first and the third columns both purport to be gcc-4_0-darwin, but the results are different! How can that be? Both tests were run today, and I haven't touched the code since yesterday. -- Eric Niebler Boost Consulting www.boost-consulting.com

What exactly the toolset "como-4_3_3-vc7_1" stands for? Thanks, Arkadiy

What does a blank space (as opposed to "pass"/"fail"/"n/a") mean in the regression table? Thanks, Arkadiy

[mpl] broken count and at metafunctions
by Matt Calabrese 01 Sep '05

01 Sep '05

As much as I love MPL, I have come across a couple more problems. First, on MSVC++ 7.1, "count" returns 0 with maps, when there is an element in the map with the specified key (and probably on other compilers as well, though I haven't checked the implementation). As well, while a 3-argument form of "at" is described in documentation (where the third argument is the default type returned by "at" if an element with the provided key does not exist in the container), it does not appear to be implemented in 1.33. -Matt Calabrese

Boost.Threads doc bugs
by Merlyn Morgan-Graham 01 Sep '05

01 Sep '05

First time posting, please let me know if this is not the proper forum to relay this information. An aside: It seems that it might be useful to have a form on the website for reporting doc bugs (ie those found while browsing html versions)? Getting down to business: http://www.boost.org/doc/html/threads.html#id1357428 "The technique is well-know and is explained in ." http://www.boost.org/doc/html/thread/acknowledgements.html "William E. Kempf was the architect, designer, and implementor of ." If I remember correctly, I've seen other cases in boost docs where information was missing from the end of the sentence with a " ." (<single space or white space in general><dot>), so grepping all docs for this might prove useful? Again, let me know if this should be relayed differently. -Merlyn

[Boost-bugs] [ boost-Bugs-1277742 ] Serialization 1.33 assertion failure when deserializing STL
by SourceForge.net 01 Sep '05

Bugs item #1277742, was opened at 2005-08-31 15:50 Message generated for change (Tracker Item Submitted) made by Item Submitter You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=107586&aid=1277742&group_… Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: serialization Group: None Status: Open Resolution: None Priority: 5 Submitted By: Zach Laine (tzlaine) Assigned to: Robert Ramey (ramey) Summary: Serialization 1.33 assertion failure when deserializing STL Initial Comment: I am seeing an assertion failure in reset_object_address. The assertion output is: /tmp/boost_cvs/libs/serialization/src/basic_iarchive.cpp:266: void boost::archive::detail::basic_iarchive_impl::reset_object_address(const void*, const void*): Assertion `object_id_vector[i].address >= ol d_address' failed. These are the values in the failed assertion: i == 1 object_id_vector[i].address == 0x43ef0920 old_address == 0xbfffe240 For good measure, new_address == 0x43ee7830 and this == 0x43eeffc0 at the point of failure. I don't know if that indicates that old_address is garbage, or if it is supposed to be that far away from the other addresses. This is the same assertion failure reported in bug #1262084, but I am not using polymorphic archives. I verified that the test code submitted for that bug fails for me as well, but when I converted it to non-polymorphic archives, it works fine. Therefor I have no idea if these bugs are related. The code producing the failure worked fine under version 1.32. Unfortunately, the code that produces this failure is pretty involved. All my attempts to produce a minimal set of code that provokes the failure have failed. The object producing the failure is being serialized through a pointer-to-base. The inheritance of the object's class is Wnd -> Control -> TextControl. The object within the TextControl that is actually producing the failure is m_line_data, which is a std::vector. I have two fairly minimal serialize methods that I have created for the object being loaded when the failure occurs -- one of which works and on of which does not. Method A works: template <class Archive> void GG::TextControl::serialize(Archive& ar, const unsigned int version) { ar & BOOST_SERIALIZATION_NVP(m_line_data); } Method B fails: template <class Archive> void GG::TextControl::serialize(Archive& ar, const unsigned int version) { ar & BOOST_SERIALIZATION_BASE_OBJECT_NVP(Control) & BOOST_SERIALIZATION_NVP(m_line_data); } The XML file produced using A: <?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <!DOCTYPE boost_serialization> <boost_serialization signature="serialization::archive" version="3"> <new_plan_text_control class_id="0" tracking_level="1" version="0" object_id="_0"> <m_line_data class_id="1" tracking_level="0" version="0"> <count>1</count> <item class_id="2" tracking_level="0" version="0"> <char_data class_id="3" tracking_level="0" version="0"> <count>0</count> </char_data> <justification>8</justification> </item> </m_line_data> </new_plan_text_control> </boost_serialization> The XML file produced using B: <?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <!DOCTYPE boost_serialization> <boost_serialization signature="serialization::archive" version="3"> <new_plan_text_control class_id="0" tracking_level="1" version="0" object_id="_0"> <Control class_id="1" tracking_level="1" version="0" object_id="_1"> <Wnd class_id="2" tracking_level="1" version="0" object_id="_2"> <m_text></m_text> <m_done>0</m_done> <m_parent class_id="-1"></m_parent> <m_children class_id="3" tracking_level="0" version="0"> <count>0</count> </m_children> <m_zorder>0</m_zorder> <m_visible>1</m_visible> <m_clip_children>0</m_clip_children> <m_upperleft class_id="4" tracking_level="0" version="0"> <x>0</x> <y>0</y> </m_upperleft> <m_lowerright> <x>150</x> <y>25</y> </m_lowerright> <m_min_size> <x>0</x> <y>0</y> </m_min_size> <m_max_size> <x>1073741824</x> <y>1073741824</y> </m_max_size> <m_filters class_id="5" tracking_level="0" version="0"> <count>0</count> </m_filters> <m_filtering class_id="6" tracking_level="0" version="0"> <count>0</count> </m_filtering> <m_layout class_id="-1"></m_layout> <m_containing_layout class_id="-1"></m_containing_layout> <m_flags>0</m_flags> </Wnd> <m_color class_id="8" tracking_level="0" version="0"> <r>0</r> <g>0</g> <b>0</b> <a>0</a> </m_color> <m_disabled>0</m_disabled> </Control> <m_line_data class_id="9" tracking_level="0" version="0"> <count>1</count> <item class_id="10" tracking_level="0" version="0"> <char_data class_id="11" tracking_level="0" version="0"> <count>0</count> </char_data> <justification>8</justification> </item> </m_line_data> </new_plan_text_control> </boost_serialization> Below is the stack at the point of failure.
