[serialization]A question about the implementation of XML_name in basic_xml_oarchive.ipp
by Sean Huang 30 Sep '05

30 Sep '05

I ran across the implementation of XML_name. It is a functor used to validate each single character in an XML name. The initialization of a stack-based look-up table everytime the functor is called puzzles me (see excerpt below). void operator()(CharType t) const{ unsigned char lookup_table[] = { 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0, 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0, 0,0,0,0,0,0,0,0,0,0,1,1,0,0,0,0, // -. 1,1,1,1,1,1,1,1,1,1,0,0,0,0,0,0, // 0-9 0,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1, // A- 1,1,1,1,1,1,1,1,1,1,1,0,0,0,0,1, // -Z _ 0,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1, // a- 1,1,1,1,1,1,1,1,1,1,1,0,0,0,0,0, // -z 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0, 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 }; if((unsigned)t > 127) return; if(0 == lookup_table[(unsigned)t]) boost::throw_exception( xml_archive_exception( xml_archive_exception::xml_archive_tag_name_error ) ); } Is there any reason why it was done this way? For threading issues? Thanks, Sean

It looks like a semicolon was omitted just before "ECHO" Building Boost.Iostreams with bzip2 support disabled. ECHO To enable bzip2, consult the Boost.Iostreams documentation -- Dave Abrahams Boost Consulting www.boost-consulting.com

[filesystem] GetFileAttributesExA and Windows 95
by Angus Leeming 29 Sep '05

29 Sep '05

Beman, you use the WinAPI call GetFileAttributesExA only twice in Boost.Filesystem, in _is_empty and file_size, but that means that the code won't run on Windows 95: file is linked to missing export KERNEL32.DLL:GetFileAttributesExA The msdn docs http://msdn.microsoft.com/library/en-us/fileio/fs/getfileattributesex.asp suggest that Win95 support requires only that you grab NewAPIs.h from the SDK Update Site. Here's an example of how it should be used: ========================================================================== http://codeproject.com/win32/harddiskspace.asp?df=100&forumid=15107&exp=0&s… #define COMPILE_NEWAPIS_STUBS #define WANT_GETDISKFREESPACEEX_WRAPPER then in the file where you use GetDiskFreeSpaceEx.... #include <newapis.h> ========================================================================== Alternatively, I append a naïve implementation of the two files using GetFileAttributes and GetFileSize. Is any of this useful? Regards, Angus BOOST_FILESYSTEM_DECL bool _is_empty( const path & ph ) { DWORD const attributes = GetFileAttributes( ph.string().c_str() ); if ( attributes & INVALID_FILE_ATTRIBUTES ) boost::throw_exception( filesystem_error( "boost::filesystem::is_empty", ph, fs::detail::system_error_code() ) ); if ( attributes & FILE_ATTRIBUTE_DIRECTORY ) return is_empty_directory( ph ); DWORD file_size_high = DWORD const file_size_low = ::GetFileSize( ph.string().c_str(), &file_size_high ); if ( file_size_low == INVALID_FILE_SIZE ) { if ( GetLastError() = NO_ERROR ) boost::throw_exception( filesystem_error( "boost::filesystem::is_empty", ph, fs::detail::system_error_code() ) ); return ( !file_size_high && !file_size_low ); } BOOST_FILESYSTEM_DECL boost::intmax_t file_size( const path & ph ) { DWORD const attributes = GetFileAttributes( ph.string().c_str() ); if ( attributes & INVALID_FILE_ATTRIBUTES ) boost::throw_exception( filesystem_error( "boost::filesystem::is_empty", ph, fs::detail::system_error_code() ) ); if ( attributes & FILE_ATTRIBUTE_DIRECTORY ) boost::throw_exception( filesystem_error( "boost::filesystem::file_size", ph, "invalid: is a directory", is_directory_error ) ); DWORD file_size_high = DWORD const file_size_low = ::GetFileSize( ph.string().c_str(), &file_size_high ); if ( file_size_low == INVALID_FILE_SIZE ) { if ( GetLastError() = NO_ERROR ) boost::throw_exception( filesystem_error( "boost::filesystem::is_empty", ph, fs::detail::system_error_code() ) ); return (static_cast<boost::intmax_t>( file_size_high ) << (sizeof( file_size_low )*8)) + file_size_low }

I had been using Boost test with 1.32 successfully #include <boost/test/test_tools.hpp> #include <boost/test/floating_point_comparison.hpp> // Extra test tool for FP comparison. but with 1.33 it fails to compile at using boost::unit_test_framework::unit_test_log; using boost::unit_test_framework::log_level; and used this to control the log threshold unit_test_log::instance().set_log_threshold_level_by_name("test_suite"); and to switch the log file unit_test_log::instance().set_log_stream(flog); // Switch to log file.// unit_test_log::instance().set_log_stream(cout); // Switch back to cout, But this has been removed in 1.33 but I am unclear how to replicate this sort of function. Suggestions? Thanks Paul Paul A Bristow Prizet Farmhouse, Kendal, Cumbria UK LA8 8AB +44 1539 561830 +44 7714 330204 mailto: pbristow(a)hetp.u-net.com www.hetp.u-net.com

[boostbook] BOOST_ROOT vs BOOST_BUILD_PATH
by Martin Wille 29 Sep '05

Hi, the installation script for Boostbook contains: elif test -r "$BOOST_ROOT/tools/build/v2/user-config.jam"; then JAM_CONFIG_IN="$BOOST_ROOT/tools/build/v2/user-config.jam"; Shouldn't BOOST_BUILD_PATH be checked, too?
