Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: .Net 2005 Beta 2 and VC++ 8.0 Initial Comment: Hello, I'm testing our apps with VS .Net 2005 Beta 2. I encountered some difficulties with Boost. Some samples of the errors messages I got at linkage: libboost_date_time-vc6-mt-gd-1_32.lib(greg_month.obj) : warning LNK4049: locally defined symbol ?? 1out_of_range@std@@UAE@XZ (public: virtual __thiscall std::out_of_range::~out_of_range(void)) imported libboost_date_time-vc6-mt-gd-1_32.lib(greg_month.obj) : warning LNK4217: locally defined symbol ?? 0out_of_range@std@@QAE@ABV?$basic_string@DU? $char_traits@D@std@@V? $allocator@D@2@@1@@Z (public: __thiscall std::out_of_range::out_of_range(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &)) imported in function "public: __thiscall boost::gregorian::bad_month::bad_month(void)" (?? 0bad_month@gregorian@boost@@QAE@XZ) libboost_date_time-vc6-mt-gd-1_32.lib(greg_month.obj) : warning LNK4217: locally defined symbol ?? 0out_of_range@std@@QAE@ABV01@@Z (public: __thiscall std::out_of_range::out_of_range(class std::out_of_range const &)) imported in function "public: __thiscall boost::gregorian::bad_month::bad_month (struct boost::gregorian::bad_month const &)" (?? 0bad_month@gregorian@boost@@QAE@ABU012@@Z ) libboost_signals-vc6-mt-gd-1_32.lib (named_slot_map.obj) : warning LNK4049: locally defined symbol ??1runtime_error@std@@UAE@XZ (public: virtual __thiscall std::runtime_error::~runtime_error(void)) imported libboost_signals-vc6-mt-gd-1_32.lib (named_slot_map.obj) : warning LNK4217: locally defined symbol ??0runtime_error@std@@QAE@ABV? $basic_string@DU?$char_traits@D@std@@V? $allocator@D@2@@1@@Z (public: __thiscall std::runtime_error::runtime_error(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &)) imported in function "public: __thiscall boost::bad_function_call::bad_function_call(void)" (?? 0bad_function_call@boost@@QAE@XZ) libboost_signals-vc6-mt-gd-1_32.lib (named_slot_map.obj) : warning LNK4217: locally defined symbol ?? 0runtime_error@std@@QAE@ABV01@@Z (public: __thiscall std::runtime_error::runtime_error(class std::runtime_error const &)) imported in function "public: __thiscall boost::bad_function_call::bad_function_call (class boost::bad_function_call const &)" (?? 0bad_function_call@boost@@QAE@ABV01@@Z) I also found some compile-time errors, but I think it is our fault, I must investigate some more. Did boost 1.32 work with VS .Net 2005 beta 2? I'm sure I'm not the first to try. Any advice about this issue or others? If a new release of Boost is needed, is a team working on it? How can I help? Our old compiler was VC++ 6.0, I use Boost 1.32, latest release.

One additional thought occurred to me. How does Boost.Optional handle cases where object construction fails? I'm not sure how many approaches exist to the problem of failed constructors, but I think most programmers agree that constructors should rarely (if ever) be allowed to throw an exception. Would it make sense for Boost.Optional to detect failed constructors and consider those objects uninitialized? Here is a contrived example: // -- begin class construct_status { /* TBD */ }; class foo : public construct_status { int *i; public: foo() throw() : i(new(nothrow) int) { if( !i ) { this->construct_status::set_bad(); } else { this->construct_status::set_good(); } } }; boost::optional<foo> x = foo(); if( !x ) { // end up here if the foo constructor called construct_status::set_bad } // -- end It seems that if Boost.Optional users must always test for initialization anyway, we could add a valid object check for free. I would be interested to hear what others think about this. -Andy

MS compiler detection
by Ulrich Eckhardt 11 Jul '05

11 Jul '05

Hi! I ported large parts of Boost 1.32 to embedded Visual C++ 4 some time ago. One of the major changes was because the included cross compilers reported _MSC_VER somewhere in between 1200 and 1202. IOW, a plethora of cases that checked ==1200 or >1200 failed to work for a few of them. I already once submitted a patch, but it hasn't been incorporated yet, so here is one against CVS from this afternoon. The changes I made were mostly mechanical: MSC_VER <= 1200 -> MSC_VER < 1300 MSC_VER == 1200 -> MSC_VER < 1300 MSC_VER >= 1300 -> MSC_VER > 1200 Some other changes were that I corrected a few comments that spoke of only VC6, but there are too many of them - I didn't get them all. Another change was that I prepared the autolinking feature for evc4. I tested the changes on a mirror of CVS from 6 months ago, and so far it seems to work with evc4, vc6 and vc7.1. BTW-1: I also noticed the same problem with other compilers/versions, i.e. there are checks like 'MSC_VER > 1310' targeting VC8. This will fail if there comes a service pack with a compiler with version 13.11, not an acute problem though, just something to keep in mind perhaps. BTW-2: There are a few cases where the compiler version was used to check for a feature of the standardlibrary some variants of it came bundled with. I think I marked these places with a 'TODO' tag. For all who wonder, there is no real standardlibrary shipped with evc4, neither a C nor a C++ one. STLport is mandatory therefore. Also, the functions of the win32 API that use TCHAR=char are also almost gone, but those are another patch another day. A last thing is that when linking, the name of the lib must not be larger than 32 chars, or the runtime linker won't be able to find the lib. Explicit loading with LoadLibrary still works. Guess how much blood, sweat&tears it took me to find out ... the threads lib which is the only one I need is 33 chars or somesuch. Please commit these changes, they are easy to verify and nonintrusive for unaffected compilers, thanks. Uli

[iostreams] request for advice on naming [repost]
by Jonathan Turkanis 11 Jul '05

11 Jul '05

Dear all, I'm considering some last minute name changes for the iostreams library, and would like some feedback. There are two issues: 1. the names of the fundamental components streambuf_facade and stream_facade 2. inconsistent header names (Note: these changes shouldn't affect the regression tests -- unless I botch them) ----------------------- streambuf_facade and stream_facade: Before I settled on "streambuf_facade" and "stream_facade," I tried five or six other pairs of names for these templates. I finally picked the current names because of the analogy with the iterators library. However, the templates are not really facades -- in the GOF sense -- and I'm not sure that the analogy with the iterators library will be very effective in helping users understand these templates. As a result, I'm think of using the less technical-sounding names "generic_streambuf" and "generic_stream." What do people think? ----------------------- inconsistent header names: Until now I've followed the policy that a header should have the same name as the component it contains, if it contains a single component, and a short descriptive name if it contains several related components. For example, the header regex_filter.hpp contains the single component regex_filter, while the header zlib.hpp contains the component zlib_error, zlib_params, zlib_compressor and zlib_decompressor. This policy has resulted in a peculiar mix of names. For instance, boost/iostreams/filter now contains: bzip2.hpp counter.hpp gzip.hpp line_filter.hpp newline.hpp one_step_filter.hpp regex_filter.hpp stdio_filter.hpp symmetric_filter_adapter.hpp test.hpp zlib.hpp As you can see, some contain "_filter" and some don't, and it all depends on whether the header contains more than one component, which can be hard to remember. I'm thinking of renaming the headers that are curently based on component names so that all headers will have short, simple names. E.g., bzip2.hpp counter.hpp gzip.hpp line.hpp newline.hpp one_step.hpp regex.hpp stdio.hpp symmetric.hpp test.hpp zlib.hpp Thoughts? Best Regards, Jonathan

This is the first reason why the notion > of Boost.Optional being a model of OptionalPointee appeals to me. Our opinions differ on this point. I believe there are cases where providing a default object is quite appropriate, but again, it all depends on the application. If, as you say, an "invariant in user code" can be used to control a program's behavior, why can't the defined and documented behavior of default object delivery serve as the invariant -- especially if it simplifies syntax? > Regarding full operator support: > I'm very skeptic about this design aim, mainly because it is > an attempt at making the class as a whole a transparent > wrapper around the underlying object, which is fundamentally > not possible in C++ and will only cause confusion.

I would say we mostly agree, except that I believe there are cases where guaranteed object delivery is useful. Perhaps something like dual_state would be best built as an addition to Boost.optional, as David Abrahams has suggested. So we could say Boost.optional is a robust and appropriate design, and dual_state may offer some useful (though, uh, optional) additions to Boost.optional. Thanks again. -Andy

[thread] patch for borland regression
by Tobias Schwinger 11 Jul '05

11 Jul '05

Hi, here is a patch for the Borland regression of Boost.Thread. The problem: ------------ For some odd reasons BCC 5.6.4 fails to export a symbol for the destructor of read_write_mutex_impl. Solution annotations: --------------------- 1.1. Forced template instantiation of the destructor (which again needed a workaround, because explicit instantiation of a destructor does not seem to work) and it did not help 1.2. The destructor currently only contains assertions so I ended up commenting it 2.1. There are still some warnings (unreachable code, condition always true) wasn't sure whether it's safe to disable them 2.2. Tested with 5.6.5 and it works without the workaround (that's why there is no BOOST_TESTED_AT) 2.3. Tested with 5.5.0 and 5.5.1 and solved another minor problem with windows headers (size_t isn't visible at root namespace when compiling once.cpp) 2.4. Compiled and ran the read_write_mutex test for all compilers and it passed 2.5. Someone should perhaps test if Kylix needs the 5.6.4-workaround as well Regards, Tobias Index: boost/thread/read_write_mutex.hpp =================================================================== RCS file: /cvsroot/boost/boost/boost/thread/read_write_mutex.hpp,v retrieving revision 1.8 diff -u -r1.8 read_write_mutex.hpp --- boost/thread/read_write_mutex.hpp 29 Mar 2005 21:45:54 -0000 1.8 +++ boost/thread/read_write_mutex.hpp 3 Jul 2005 23:31:39 -0000 @@ -19,6 +19,7 @@ #include <boost/thread/detail/config.hpp> #include <boost/utility.hpp> +#include <boost/detail/workaround.hpp> #include <boost/thread/mutex.hpp> #include <boost/thread/detail/lock.hpp> @@ -52,7 +53,9 @@ typedef detail::thread::scoped_timed_lock<Mutex> scoped_timed_lock; read_write_mutex_impl(read_write_scheduling_policy::read_write_scheduling_policy_enum sp); +#if !BOOST_WORKAROUND(__BORLANDC__,<= 0x564) ~read_write_mutex_impl(); +#endif Mutex m_prot; Index: libs/thread/src/read_write_mutex.cpp =================================================================== RCS file: /cvsroot/boost/boost/libs/thread/src/read_write_mutex.cpp,v retrieving revision 1.20 diff -u -r1.20 read_write_mutex.cpp --- libs/thread/src/read_write_mutex.cpp 3 May 2005 20:42:09 -0000 1.20 +++ libs/thread/src/read_write_mutex.cpp 3 Jul 2005 23:36:16 -0000 @@ -27,6 +27,8 @@ #include <boost/thread/read_write_mutex.hpp> #include <boost/thread/xtime.hpp> +#include <boost/detail/workaround.hpp> + #if !defined(BOOST_NO_STRINGSTREAM) # include <sstream> #endif @@ -376,6 +378,7 @@ , m_readers_next(true) {} +#if !BOOST_WORKAROUND(__BORLANDC__, <= 0x564) template<typename Mutex> read_write_mutex_impl<Mutex>::~read_write_mutex_impl() { @@ -390,6 +393,7 @@ BOOST_ASSERT(m_num_waking_readers == 0); BOOST_ASSERT(m_num_max_waking_readers == 0); } +#endif template<typename Mutex> void read_write_mutex_impl<Mutex>::do_read_lock() Index: libs/thread/src/once.cpp =================================================================== RCS file: /cvsroot/boost/boost/libs/thread/src/once.cpp,v retrieving revision 1.19 diff -u -r1.19 once.cpp --- libs/thread/src/once.cpp 17 Jul 2004 04:33:59 -0000 1.19 +++ libs/thread/src/once.cpp 3 Jul 2005 23:25:19 -0000 @@ -11,11 +11,17 @@ #include <boost/thread/detail/config.hpp> +#include <boost/detail/workaround.hpp> + #include <boost/thread/once.hpp> #include <cstdio> #include <cassert> + #if defined(BOOST_HAS_WINTHREADS) +# if BOOST_WORKAROUND(__BORLANDC__,<= 0x551) + using std::size_t; +# endif # include <windows.h> # if defined(BOOST_NO_STRINGSTREAM) # include <strstream>
