is there a boost "storable_type"?
by Stjepan Rajko 19 Apr '07

19 Apr '07

Hi, I am wondering if there is a construct in boost which, given a type T, returns the underlying "storable" type - say if T is int & the "storable_type" should be int. I'm not sure if the word "storable" is the best word... The scenario I am facing is making a function call that takes a parameter of type T, where I need to prepare the parameter before calling (specifically, deserializing it from an archive). Hence, as far as I can tell, I need to declare a variable of the underlying storable type, and get the right value inside it. So far, I've been using: template<typename T> struct storable : public boost::remove_const<typename boost::remove_reference<T>::type > {}; but I'm not sure if that cuts it in all situations. In any case, I figured the right thing might be in Boost already and I just haven't found it. Any suggestions? Thanks! Stjepan

[filesystem] patch for path.hpp for "Duplicate symbol" problem on HP-UX and Tru64
by Boris Gubenko 19 Apr '07

Vladimir Prus wrote: > Boris, > since this a patch for boost.filesystem, I think you better post it > to Boost mailing list, not Boost.Build mailing list. We don't have > the authority to approve boost.filesystem patches here. Posting to the right list. Thanks, Vladimir! ---------------------------------------------------------------------------- On HP-UX and Tru64, when using CVS HEAD, linking of process_jam_log fails because of multiply defined symbol. From ld output on HP-UX, for example: ld: Duplicate symbol "boost::filesystem::basic_filesystem_error<boost:: filesystem::basic_path<std::basic_string<char,std::char_traits<char>, std::allocator<char> >,boost::filesystem::path_traits> >::what() const" The duplicate symbol is coming from the explicit specialization in boost/filesystem/path.hpp conditionalized for anything but gcc with the following comment: // TODO: Figure out why this specialization is causing problems with GCC #ifndef __GNUC__ ... With aCC (HP-UX) and cxx (Tru64), this specialization is causing linker's muldef if several modules include header file with the specialization. According to reproducer below, this is the same problem with gcc also, although I don't know what "problems with GCC" the comment above refers to. This specialization does not cause a problem with Intel compiler for Itanium: see output for intel_ecc and iVMS below. Attached patch fixes the problem on HP-UX/aCC and Tru64/cxx by extending condition under which the specialization is not provided (before the fix, it was not provided for gcc only). I verified that it fixes the problem on the aforementioned platforms. Ok to commit?

I don't understand this - why can't I read in data from a file? ifstream f("data.txt"); context<decimal32> ctx; decimal32 x, y, z; ctx(f >> x >> y); // not implemented yet, but certainly could be z = ctx(x + y); >I'll also say that I don't find the above syntax natural...I just think > >decimal32 x(9912), y("9e+4"); >decimal32 z = x + y; > >would be more expected. I'm sure you have good reasons, but from my >perspective a number type should behave as much like a built-in type as possible. This I totally understand, and agree with, but I'm not sure what the perfect solution is. My idea is to provide a user-customizable context class for all operations, and a lot of design decisions derive from this. The binary operations essentially have become TRInary operations; it isn't +(x,y), but rather +(x,y,context). Context participates in the operation. So the question is, how do we implement this without forcing the user to do something really ugly like: z = add(x, y, context); My solution was to wrap the expression in an instance of context. I've also provided for a default context so that you actually can use the syntax you prefer, but you lose a little flexibility: z = x + y; // uses default context x = z * z; // still using default context z = ctx(x + y); // uses context instance ctx x = ctx2(z * z); // uses a new context instance ctx2 The default context is currently implemented using a singleton (I'm aware that there are some real-world usage concerns about singletons). >> 2.

Well, this does make some sense, especially considering the plan to move to a hardware implementation at some point. Also, N2198 explicitly states that they're going for some level of C compatibility; obviously exceptions wouldn't fit that mold. >> 3.

The problem with the type restriction is that there are some cases where you want speed and some where you really care about memory. If I just say "decimal32" I can't distinguish the two. As you say, though, in a hardware implementation the distinction goes away, because all the bit-twiddling necessary to work with IEEE754r decimals is done fast in hardware. >Sorry, that's a complicated position for a yes/no question ;-) That's OK - thanks for your comments! - James Jones Administrative Data Mgmt.

[multi-array] constructor bypass patch
by Neal Becker 19 Apr '07

19 Apr '07

This proposed patch allows bypassing of default constructors. This can be important for high performance computing. What this patch does: 1. Add an optional arg to 'allocate_space' to specify if element construction is wanted 2. Add 'default_do_init' static constant, which is false for POD and for std::complex<T> 3. Also bypass construction when the result is going to be immediately overwritten (copy_n) 4. Add to 'allocate_space' and optional init value, which default to T(). The purpose is to allow for a multi_array constructor that specifies an initial fill value. This is another optimization and consistent with STL containers. However, I haven't figured out how to use this yet.

[1.34.0] [iostreams] patch - boost_bzip2 contains the symbol "main"
by Takeshi Mouri 19 Apr '07

19 Apr '07

Hello, I found the symbol "main" in the boost_bzip2 libraries. The function main() is contained in the file "mk251.c". This is for testing, so we doesn't need it. The attachment is a trivial patch for this problem. Regards, Takeshi Mouri

[iostreams] file_descriptor::read bug?
by Xi Wang 19 Apr '07

19 Apr '07

In the source libs/iostreams/src/file_descriptor.cpp, file_descriptor::read, line 147, I think return static_cast<std::streamsize>(result); should be return static_cast<std::streamsize>(result == 0? -1: result); The Windows API ReadFile returns TRUE with result == 0 when it has come to end-of-file. Regards, Xi

The ( ) confuses the bat file big time and I had to workaround it by using quotes and DeQuote function. * tools/build/jam_src/build.jam and tools/build/jam_src/jambase.c Simply new "vc8" tool * tools/build/jam_src/pathunix.c Changed DWORD -> int because on VC8 DWORD is unsigned which causes problem when we have pos=0 (then prev_pos is a huge number and everything is screwed). * boost/config/abi/msvc_prefix.hpp Make alignment consistent with STLPort. * boost/config/abi/msvc_prefix.hpp It seems that this workaround is not needed in the final version of VC 8 * libs/thread/src/once.cpp This is a known issue (http://lists.boost.org/boost-users/2005/09/13765.php) Unfortunately, I can't figure out a better way to fix this. ---------------------------------------------------------------------- >Comment By: Rene Rivera (grafik) Date: 2007-04-18 21:47 Message: Logged In: YES user_id=33595 Originator: NO Boost.Jam in CVS already has many fixes to support both cross x64 and native x64 building.

Is it worthwhile at all to continue to work on a BOOST > library for fixed decimal arithmetic without making it N2198 compliant? I brought this up a couple of weeks ago but the discussion got sidetracked by my thread safety question. I'm reasonably satisfied that N2198 can be written in a threadsafe way using <cfenv> now (if the fenv implementation is threadsafe, that is), but I'm still not totally happy with the extremely restrictive N2198 interface. So here's my question again: Is there any interest in a Boost library that implementated decimal arithmetic but didn't use N2198? What I have working now would use expression templates to implement context: context<decimal32> ctx; decimal32 x = ctx(9912), y = ctx("9e+4"); decimal32 z = ctx(x + y); z = ctx(x * y); z = ctx(x - (3 * z)); The expressions (e.g. "x*y") are evaluated within a context<decimal32> instance, which does exception trapping, etc. This gives the library user a lot of control - it also would easily allow a user to derive from context to implement their own behaviors. There is also a facility for using a default singleton context as well for code that needs to be written in the form: z = x * y; There are several usage differences between my proposal and N2198: 1. N2198 is simpler to understand because it doesn't rely on expression templates. No question here. 2. However, in the presence of exceptions I believe that my usage is simpler than what is required by N2198, which is going to result in hardware traps and/or signals, rather than nice C++ exceptions. With a context class you can throw exceptions or allow user-defined behavior. 3. N2198 restricts users to 3 decimal types, which presumably match the IEEE754r implementation of decimal types. These are great for memory usage, but not so hot for performance, at least when implemented in software - too much bit-twiddling. A straightforward implementation of decimals using arrays to store coefficients is much less space-efficient, but runs faster. (My very rudimentary testing indicates that the ratio is around 2.5:1 on my hardware, a Sun server.) - James Jones Administrative Data Mgmt.
