-
Fixed the points example, as pointed out by 沈慧峰.
-
Use declarations for standard classes, so that the library doesn't need
to include all of their headers
-
Deprecated the
<boost/functional/hash headers. Now a single header,
<boost/functional/hash.hpp>
is used.
-
Add support for the
BOOST_HASH_NO_EXTENSIONS
macro, which disables the extensions to TR1.
-
Minor improvements to the hash functions for floating point numbers.
-
Update the portable example to hopefully be more generally portable.
-
Ticket 952:
Suppress incorrect 64-bit warning on Visual C++.
-
Support for
long long,
std::complex.
-
Improved algorithm for hashing floating point numbers:
-
Improved portablity, as described by Daniel Krügler in a
post to the boost users list.
-
Fits more information into each combine loop, which can reduce the
the number of times combine is called and hopefully give a better
quality hash function.
-
Improved the algorithm for hashing floating point numbers.
-
On Cygwin use a binary hash function for floating point numbers,
as Cygwin doesn't have decent floating point functions for
long double.
-
Never uses
fpclass
which doesn't support long
double.
-
Ticket 1064:
Removed unnecessary use of
errno.
-
Explicitly overload for more built in types.
-
Minor improvements to the documentation.
-
A few bug and warning fixes:
-
Ticket 1509:
Suppress another Visual C++ warning.
-
Some workarounds for the Sun compilers.
-
Stop using OpenBSD's dodgy
std::numeric_limits.
-
Using the boost typedefs for
long
long and unsigned
long long.
-
Move the extensions into their own header.
-
Ticket 2264:
In Visual C++, always use C99 float functions for
long
double and float
as the C++ overloads aren't always availables.
-
Changed the warnings in the deprecated headers from 1.34.0 to errors. These
will be removed in a future version of Boost.
-
Moved detail headers out of
boost/functional/detail,
since they are part of functional/hash, not functional. boost/functional/detail/container_fwd.hpp
has been moved to boost/detail/container_fwd.hpp
as it's used outside of this library, the others have been moved to boost/functional/hash/detail.
-
Move the hash_fwd.hpp implementation into the hash subdirectory, leaving
a forwarding header in the old location. You should still use the old location,
the new location is mainly for implementation and possible modularization.
-
Ticket 2412:
Removed deprecated headers.
-
Ticket 2957:
Fix configuration for vxworks.
-
Automatically configure the float functions using template metaprogramming
instead of trying to configure every possibility manually.
-
Workaround for when STLport doesn't support long double.
-
Reduce the number of warnings for Visual C++ warning level 4.
-
Some code formatting changes to fit lines into 80 characters.
-
Rename an internal namespace.
-
Ticket 3866:
Don't foward declare containers when using gcc's parallel library, allow
user to stop forward declaration by defining the
BOOST_DETAIL_NO_CONTAINER_FWD
macro.
-
Ticket 4038:
Avoid hashing 0.5 and 0 to the same number.
-
Stop using deprecated
BOOST_HAS_* macros.
-
Add option to prevent implicit conversions when calling
hash_value
by defining BOOST_HASH_NO_IMPLICIT_CASTS.
When using boost::hash for a type that does not have hash_value declared but does have an
implicit conversion to a type that does, it would use that implicit conversion
to hash it. Which can sometimes go very wrong, e.g. using a conversion
to bool and only hashing to 2 possible values. Since fixing this is a breaking
change and was only approached quite late in the release cycle with little
discussion it's opt-in for now. This, or something like it, will become
the default in a future version.
-
Avoid warning due with gcc's
-Wconversion flag.
-
Ticket 6771:
Avoid gcc's
-Wfloat-equal
warning.
-
Ticket 6806:
Support
std::array and std::tuple
when available.
-
Add deprecation warning to the long deprecated
boost/functional/detail/container_fwd.hpp.
-
Support the standard smart pointers.
-
hash_value now implemented
using SFINAE to avoid implicit casts to built in types when calling it.
-
Updated to use the new config macros.
-
Restore
enum support, which
was accidentally removed in the last version.
-
New floating point hasher - will hash the binary representation on more
platforms, which should be faster.
-
Add support for
boost::int128_type and boost::uint128_type
where available - currently only __int128
and unsigned __int128
on some versions of gcc.
-
On platforms that are known to have the standard floating point functions,
don't use automatic detection - which can break if there are ambiguous
overloads.
-
Fix undefined behaviour when using the binary float hash (Thomas Heller).
-
Simplify a SFINAE check so that it will hopefully work on Sun 5.9 (#8822).
-
Suppress Visual C++ infinite loop warning (#8568).
-
Removed some Visual C++ 6 workarounds.
-
Ongoing work on improving
hash_combine.
This changes the combine function which was previously defined in the reference
documentation.
-
Fixed some warnings.
-
Only define hash for
std::wstring
when we know we have a wchar_t.
Otherwise there's a compile error as there's no overload for hashing the
characters in wide strings (#8552).
-
Fix for recent versions of Visual C++ which have removed
std::unary_function and std::binary_function
(#12353).
-
Support for
char16_t, char32_t, u16string,
u32string
-
Avoid float comparison warning when using Clang - this workaround was already
in place for GCC, and was used when Clang pretends to be GCC, but the warning
was appearing when running Clang in other contexts.
