Log message:
boost: Update to 1.81.0
Changelog:
Version 1.81.0
New Libraries
* URL: A library for parsing, modifying, and printing URLs using only C++11,
from Vinnie Falco and Alan de Freitas. Features include fast compilation,
strong invariants, and strict compliance using a memory-friendly approach.
Updated Libraries
* Asio:
+ Added the consign completion token adapter, which can be used to attach
additional values to a completion handler.
+ Added any_completion_handler<>, which can be used to type-erase
completion handlers.
+ Added experimental::co_composed to enable lightweight implementations
of user-defined asynchronous operations using C++20 coroutines.
+ Add range-based experimental::make_parallel_group() overloads.
+ Added any_completion_executor, a type-erased wrapper for executors that
are associated with completion handlers.
+ Added missing context query to use_future's executor.
+ Added nothrow constructor overloads to execution::any_executor<> and
any_io_executor.
+ Optimised representation of empty execution::any_executor objects to
improve the performance of copy and move operations.
+ Added an associated_cancellation_slot specialisation for std::
reference_wrapper.
+ Changed I/O objects to return their executors by const reference.
+ Changed associated to use deduced return types for all two-argument get
functions.
+ Fixed spawn implementation to catch unhandled exceptions and rethrow
them outside of the spawned "thread".
+ Fixed spawn to ensure the completion handler is dispatched through the
correct executor.
+ Fixed cleanup of of terminal-state spawn "thread" objects.
+ Fixed spawn and co_spawn implementations to dispatch cancellation
handlers on the correct executor.
+ Changed semantics of 'dispatch' to mean the executor is used as-is.
+ Deprecated the execution::execute customisation point and sender/
receiver facilities.
+ Added a C++11 parallel_group example.
+ Fixed example code to not use the deprecated resolve conversions.
+ Fixed an ambiguity in experimental::channel_traits specialisations.
+ Added a specialised channel implementation for the for R(error_code)
signature.
+ Made cancelled() public on the async_compose 'self' object.
+ Added io_executor_type and get_io_executor to the async_compose 'self'
object.
+ Fixed implementation of release() for Windows overlapped handles.
+ Enabled deferred awaiting for experimental::coro, regularised
experimental::use_coro, and fixed allocator handling.
+ Cleaned up experimental::promise and made it an asynchronous operation
object.
+ Constrained post/defer overloads on ability to require blocking.never.
+ Changed descriptor implementation to fall back to fcntl if ioctl fails
with ENOTTY when setting non-blocking mode.
+ Fixed Xcode deprecation warnings related to use of sprintf.
+ Fixed the arguments passed to select_reactor::run when it is run on an
internal thread.
+ Fixed compilation errors when BOOST_ASIO_DISABLE_SMALL_BLOCK_RECYCLING
is defined.
+ Updated detection of C++20 coroutine support on clang 14 and later.
+ Changed standard library feature detection to always enable std::
invoke_result when targeting C++17 or later.
+ Fixed detection of return type deduction with MSVC.
+ Updated the asynchronous operation requirements to relax the
requirements on the associated executor.
+ Added io_uring to the implementation notes.
+ Consult the Revision History for further details.
* Beast:
+ Add buffers_generator
+ Add beast::http::message_generator
+ Added buffer_ref, so beast buffers can be used with asio.
+ Support for per-operation cancellation
+ C++20 awaitable examples.
+ websocket per-message compression options
+ websocket timeout option api
+ multiple content length error
+ Support for default-completion and rebind
* Container Hash:
+ Major update.
+ The specializations of boost::hash have been removed; it now always
calls hash_value.
+ Support for BOOST_HASH_NO_EXTENSIONS has been removed. The extensions
are always enabled.
+ All standard containers are now supported. This includes std::
forward_list and the unordered associative containers.
+ User-defined containers (types that have begin() and end() member
functions that return iterators) are now supported out of the box.
+ Described structs and classes (those annotated with
BOOST_DESCRIBE_STRUCT or BOOST_DESCRIBE_CLASS) are now supported out of
the box.
+ hash_combine has been improved.
+ The performance (and quality, as a result of the above change) of
string hashing has been improved. boost::hash for strings now passes
SMHasher in 64 bit mode.
+ The documentation has been substantially revised to reflect the
changes.
* Core:
+ empty_value members are now marked as constexpr.
+ Added fclose_deleter, a deleter that calls std::fclose on a pointer to
std::FILE.
+ Bit manipulation utilities in boost/core/bit.hpp now explicitly require
unsigned integers on input. (#129)
+ bit_width now returns int instead of a value of the input argument
type. This follows resolution of LWG3656.
* Describe:
+ To allow the inclusion of enumerators.hpp, bases.hpp, and members.hpp
when the option -pedantic is used, the invocation of
BOOST_DESCRIBE_ENUM has been moved from modifiers.hpp into a separate
header, modifier_description.hpp. As a consequence, modifiers.hpp no
longer includes enum.hpp. Code that has been relying on this implicit
inclusion may fail, and will need to be fixed to include enum.hpp.
* DLL:
+ Fixed path_from_handle implementation for Windows platforms, thanks to
@SaltfishAmi for the bug report 57.
* Filesystem:
+ Deprecated: path construction, assignment and appending from containers
of characters, such as std::vector<char> or \
std::list<wchar_t>, is
deprecated in v3 and removed in v4. Please use string types or
iterators instead.
+ Deprecated: boost/filesystem/path_traits.hpp header is deprecated and
will be removed in a future release. The header contained
implementation details of path and should not be used in user's code.
+ Previously deprecated APIs will now generate compilation warnings on
use. To suppress these warnings, BOOST_FILESYSTEM_ALLOW_DEPRECATED
macro can be defined when compiling user's code.
+ Fixed compilation due to a missing include on POSIX systems that do not
support *at APIs. (#250)
+ On Windows prior to 10, added a workaround for network share filesystem
that produces ERROR_INVALID_PARAMETER when constructing directory
iterators. (PR#246, #245)
+ On Windows, fixed weakly_canonical failing with an
ERROR_INVALID_FUNCTION error code if the path started with the \
"\\?\"
prefix. (#247)
+ Added support for std::string_view, boost::string_view and boost::
container::string (as well as respective wchar_t counterparts) in path
constructors, assignment and appending operations. (#208)
+ path constructors, assignment and appending operations taking a pair of
iterators will no longer accept iterators with value types that are not
one of the supported path character types.
+ On Windows, improved compatibility of directory_iterator with various
mounted filesystems and Wine releases prior to 7.21. (#255, #266)
+ On Windows, deduplicated files are now reported as regular files rather
than reparse files. (#262)
* Fusion:
+ Added fusion::identity_view (PR#240)
+ Added support for associative sequences on fusion::transform_view (PR#
239)
+ Fixed compilation for the case when fusion::reverse_view used with an
associative sequence (PR#237)
+ Fixed Clang 13 -Wdeprecated-copy warnings (PR#261)
+ A small dependency reorganization. Now boost::ref and boost::
noncopyable are used from Boost.Core (PR#249)
+ Added CI testing on Linux and MacOS for clang and gcc, fixed CI testing
on Windows (PR#245, PR#236)
+ Improved docs and fixed typos (#234, PR#235, PR#238)
* Geometry:
+ Solved issues
o #1048 Index: Fix dangling references when Indexable is returned by
value by IndexableGetter
o #1076 Union: in rare cases it might miss one polygon
o #1081 Union: due to precision it might miss interior rings
+ Bugfixes
o #1063 Intersection: fix a bug in intersection of simple spherical
polygons
o #1064 Formulas: fix a consistency issue in geodesic direct formulas
o #1088 Point: Fix regression for custom point types
o Various fixes for missing include files, warnings, C++20
compilation errors and documentation
* Histogram:
+ Major update.
+ Added new accumulators::fraction to compute fractions, their variance,
and confidence intervals
+ Added interval computers for fractions: utility::clopper_pearson,
utility::wilson_interval, utility::jeffreys_interval, utility::
wald_interval which can compute intervals with arbitrary confidence
level
+ Added utility::confidence_level and utility::deviation types to pass
confidence levels as probabilities or in multiples of standard
deviation for all interval computers, respectively
+ Fixed internal sub_array and span in C++20
* Iterator:
+ function_output_iterator now supports perfect forwarding of the
assigned values to the wrapped function object. (PR#73)
+ Fixed compilation of constructing a function_input_iterator from result
of post-incrementing another function_input_iterator. (#75)
+ The result of post-incrementing an iterator based on iterator_facade
now supports operator->. (it++)->foo is equivalent to (*it++).foo,
which was supported before.
* JSON:
+ Added object::stable_erase.
+ Added parse overload for std::istream and operator>> for value.
+ Added rvalue ref-qualified accessors for value.
+ Conversion traits were redesigned.
+ Added conversion support for described classes and enums, std::optional
, std::variant, and null-like types (including std::nullptr_t, std::
nullopt_t, and std::monotype).
+ Added non-throwing conversion from value to user types.
* LexicalCast:

New Libraries
* No new libraries.
Updated Libraries
* Asio:
+ Added a deduced trailing return type to all asynchronous operations, to
enable the new form of async_result for C++11.
+ Moved append, prepend, as_tuple, and deferred to the boost::asio
namespace, and made them compatible with C++11.
+ Made experimental::parallel_group compatible with C++11.
+ Added buffer() overloads for contiguous containers, such as std::span.
+ Added the ability for awaitable<>-based coroutines to directly co_await
operations that are packaged as function objects.
+ Changed spawn() to be a completion token-based asynchronous operation,
and added support for cancellation. The basic_yield_context token now
supports move-only and variadic result types. When targeting C++11 and
later, spawn() and basic_yield_context are implemented in terms of
Boost.Context directly.
+ Added the is_async_operation trait and async_operation concept.
+ Added the completion_signature_of trait.
+ Added converting move construction/assignment to posix descriptors,
serial ports, pipes, Windows object_handle, Windows stream handles, and
Windows random-access handles.
+ Added release() member functions to pipes, Windows stream handles, and
Windows random-access handles.
+ Enabled support for Endpoint implementations that return void pointers
from their data() member functions, as per the documented Endpoint type
requirements.
+ Removed all() and race() from experimental::promise, as experimental::
parallel_group covers this functionality.
+ Added source locations to exceptions and error codes produced by the
synchronous and asynchronous operations.
+ Fixed compatibility with OpenSSL 3.0.4 and later.
+ Fixed compatibility with with -masm=intel.
+ Explicitly stated that socket shutdown() calls are thread-safe with
respect to certain other synchronous operations on the same socket.
+ Optimised the move construction of I/O objects where only the executor
type differs.
+ Fixed the detection of std::invoke_result for clang/libc++.
+ Fixed an issue where experimental::parallel_group initiation
incorrectly moved arguments instead of forwarding them.
+ Fixed a sequencing issue in the implementation of post(), dispatch(),
and defer().
+ Fixed the awaitable<> implementation to propagate exceptions from
awaited initiation functions through the current completion handler.
+ Fixed detection of std::aligned_alloc with gcc 7.
+ Changed to avoid using the soon-to-be-deprecated std::aligned_storage
on newer compilers.
+ Fixed detection of std::aligned_alloc for older Apple platforms.
+ Removed faulty assertions from experimental::coro implementation.
+ Added defence against Qt-defined macros when building with Intel C++.
+ Changed the implementation of the select_reactor, on Windows, to ensure
that any exception resulting from failure to recreate its interrupter's
sockets will be allowed to propagate out through io_context::run().
+ Fixed various compiler warnings.
+ Updated all composed operations examples, and the C++11 timeouts
example, to use the new async_result form.
+ Added composed operation and coroutine examples for C++20.
+ Consult the Revision History for further details.
* Atomic:
+ Improved portability of endianness checks on ARM, AArch32 and AArch64
targets. (#59)
+ Fixed compilation with MSVC 14.0 (Visual Studio 2015) in C++17 mode. (#
61)
* Filesystem:
+ On Windows, added a fallback implementation for querying file
attributes in case if the file cannot be opened with
ERROR_ACCESS_DENIED error. This may allow status and symlink_status to
succeed for system files and directories that are not reparse points or
symlinks. (#234)
+ On Windows, added a workaround for FAT/exFAT filesystems that produce
ERROR_INVALID_PARAMETER when querying file attributes. This affected
status and symlink_status, which reported that files do not exist, and
directory iterators, which failed to construct, as well as other
dependent operations. (#236, #237)
+ Worked around a compilation problem on RTEMS. (PR#240)
+ On Linux, corrected switching to sendfile copy_file implementation if
copy_file_range failed with ENOSYS in runtime. The sendfile fallback
implementation used to skip the filesystem type check and could fail
for some filesystems.
+ On POSIX systems supporting openat and related APIs defined in
POSIX.1-2008 and on Windows Vista and later, improved protection of
remove_all against CVE-2022-21658 that was implemented in the previous
release. The previous fix could still result in removing unintended
files in certain conditions. Other systems remain vulnerable.
* GIL: NOTICE: We are planning BREAKING switch to C++17 as minimum required
C++ language version in one or two releases after Boost 1.80 (#676)
+ Added
o GSoC 2020: Added Perona-Malik anisotropic diffusion algorithm (PR#
500)
o GSoC 2020: Added histogram class and related functionality (PR#499)
o GSoC 2020: Added histogram equalization feature (PR#514)
o GSoC 2020: Added histogram matching algorithm (PR#515)
o GSoC 2020: Added ability to stack images either horizontally (
hstack) or vertically (vstack) (PR#506)
o GSoC 2020: Added adaptive histogram equalization algorithm (PR#516)
o GSoC 2020: Added Standard Hough Transform and circle rasterization
(PR#512)
o GSoC 2020: Added Bresenham's algorithm for line rasterization (PR#
512)
o GSoC 2021: Added rotation of image by arbitrary angle around its
center (PR#565)
o GSoC 2021: Added rasterization support for ellipse based on "An
Efficient Ellipse-Drawing Algorithm" by Jerry Van Aken (PR#585)
o Added image constructor from compatible view (PR#520)
o Added inverse function for affine matrix3x2 (PR#527)
o Added standard morphological transformations (PR#541)
o Added for_each_pixel overload for any_image (PR#648)
o Added C++17 polymorphic memory resource typedefs for image class (
PR#529)
+ Changed
o BREAKING: The required minimum C++ version is changed from from
C++11 to C++14. Currently, large parts of GIL still compile with a
C++11 compiler. However, there is no guarantee that it stays that
way, and any compilers that do not support at least C++14 are
considered unsupported as of now.
o BREAKING: any_color_converted_view() is deprecated and will be
removed in the next release. Use color_converted_view() instead,
which provides the same feature.
o BREAKING: apply_operation for any_image is deprecated and will be
removed in the next release. Use variant2::visit instead, which
provides the same feature. (PR#656)
o Moved numeric extension to core (PR#573)
o Added support for C++17's <filesystem> (PR#636) The availability of
the std::filesystem is detected automatically, unless the
BOOST_GIL_IO_USE_BOOST_FILESYSTEM macro is defined that forces the
preference of the Boost.Filesystem.
o Renamed pixel_multiply_t to pixel_multiplies_t and pixel_divide_t
to pixel_divides_t (PR#655)
o Renamed io/dynamic_io_new.hpp to io/detail/dynamic.hpp (PR#653)
o Moved function construct_matched into boost::gil::detail namespace
as it was only used by other implementation details (PR#653)
o Made packed_pixel trivially copyable and assignable (PR#679)
o Replace deprecated libtiff v4.3 typedefs with C99 fixed-size
integers (PR#685)

o Removed unnecessary numeric cast in hsv.hpp (PR#530)
o Fixed default constructor for homogeneous_color_base for reference
pixel elements (PR#542)
o Fixed returning reference to local temporary object in
subchroma_image_view (PR#556)
o Added missing header guards in diffusion.hpp (PR#568)
o Fixed any_image_view<>::const_t (PR#526)
o Fixed C++20 incompatibilities in I/O extensions (PR#617)
o Ensured all examples build without errors (PR#628)
o Fixed convolve_2d for images with float32_t channel model (PR#577)
o Fixed for_each_pixel for non-1d iterable views (PR#621)
o Fixed: is_equal_to_sixteen in PNG I/O was less-than test (PR#650)
o Re-allow devicen_t with two components (PR#654) It was
unintentionally removed in Boost 1.72
o Fixed memory leak in image class for empty dimensions (PR#649)

const_reference
* Iterator:
+ For C++11 and later, added support for perfect forwarding of values
written to function_output_iterator. (PR#73)
+ Added protection against writing to function_output_iterator a result
of dereferencing another function_output_iterator.
* JSON:
+ Added non-const value::at overloads.
+ Added the ability to manually choose endianness of the platform.
+ Added string::subview() overload.
+ Fixed segfault in array::erase(it).
+ Fixed low performance of serialize on libc++.
+ Fixed ambigious conversion to std::string_view on GCC 8.
+ Fixed parsing on big-endian platforms.
+ Fixed handling of comment after trailing comma.
* LEAF:
+ API breaking change: throw leaf::exception(....) now becomes
leaf::throw_exception(....)
+ Fixed a bug in support for a rare build configuration (exception
handling enabled, diagnostics disabled)
+ Using nullptr instead of 0 throughout
+ Fixed pedantic warnings
* Locale:
+ Deprecated support for C++03 and earlier, C++11 will be required in the
next release
+ Provide -sICU_LINK_LOCALE as a temporary replacement for -sICU_LINK
which is incompatible with Boost.Regex. -sICU_LINK_LOCALE and -
sICU_LINK are deprecated and will be replaced by ICU_*_NAME options to
be compatible with Boost.Regex

transforming empty strings
+ Fix some issues related to visibility of classes in shared libraries
(Unix only)
+ Fix compatibility with C++20 mode
+ Fix compatibility with BOOST_USE_WINDOWS_H
+ Fix build failures due to missing includes
+ Handle or suppress many warnings which makes the build log cleaner
* Log:
+ Bug fixes:
o Fixed binding incorrect local address in UDP socket-based
syslog_backend when IPv6 address is used for the syslog server. (#
181)
o Added a workaround for a bug in libstdc++ from gcc 11.2. When
max_size_decor was used on a formatting stream, std::codecvt::
do_length incorrectly accessed the input buffer and caused a buffer
overflow.
+ See changelog for more details.
* Math:
+ Deprecated C++11 support: from 2023 we will require C++14 as a minimum
standard. This will mean GCC-5 or MSVC-14.1 as a minimal requirement.
+ Add constexpr fma support, see 734.
+ Add support for the Chatterjee Correlation Coefficient, see 770.
+ Added support for the logarithm of the PDF for all the distributions.
+ Improve support for building with no exception or RTTI support.
+ Some minor bug fixes for [sub 1]F[sub 1] corner cases, see 778.
* Multiprecision:
+ Mark C++11 support as deprecated: from 2023 we will move to requiring
C++14 as a minimum standard level. That will drop support for GCC
versions prior to 5 and MSVC prior to 14.1.
+ Fix conflict between boost/cstdfloat.hpp and this library.
+ Clean up lots of gcc and clang warnings.
+ Fix input streaming of composite types (complex, interval rational)
where there is a trailing delimeter in the stream and no whitespace.
+ Fix constexpr integer square root where the input is 1, 2 or 3.
+ Add missing #include of <memory> to float128.hpp.
+ Correct 2-arg constructor for class number to prevent ambiguity in some
cases.
+ Correct and make more consistent behaviour of divide-by-zero in
gmp.hpp.
* Multi-index Containers:
+ Maintenance work.
* Nowide:
+ Major performance improvement for Bulk I/O with files
+ basic_filebuf: Fix wrong return value of sync when fflush failed
+ basic_filebuf: Fix possible undefined behavior in a corner case when
nothing was actually written but buffer is in "write" mode
+ basic_filebuf: Limit putback of characters (i.e. pbackfail) only
allowing putback of buffered characters (may be only 1 character)
* Optional:
+ Added specializations for std::hash<boost::optional<T>>. \
This is a
breaking change for programs that define such specializations
themselves. For more details see specs.
* STLInterfaces:
+ Fix #53: "missing 'typename' prior to dependent type name
'C::const_iterator'"
+ Fix #54: "Concept check fails on .data() of a view on contiguous
iterator_interface instantiations"
+ New additions to make it easy to write views and view adaptors that
work like, and interoperate with, the ones in the standard library:
o Add workalikes for C++23's std::bind_back() and std::
range_adaptor_closure for pre-C++23 code.
o Add templates closure and adaptor to make writing view adaptors
easier, following the examples in P2387.
* System:
+ When an error_code is converted to std::error_code and then back to
error_code, the original is now restored, if possible.
+ Reworked the conversion from error_category to std::error_category to
avoid the one-time allocation that shows up on leak checkers.
+ Added a constructor that allows replacing the source location of an
error_code, and a corresponding assign.
+ Added a converting constructor to result.
* Unordered: Major update:
+ Refactor internal implementation to be dramatically faster
+ Allow final Hasher and KeyEqual objects
+ Update documentation, adding benchmark graphs and notes on the new
internal data structures
* Utility:
+ In string_view/string_ref, fixed max_size returning incorrect value. (#
91)
+ Removed noexcept specifier from string_view::compare as it may throw on
some input arguments. (#94)
+ In string_view/string_ref, added support for calling substr with no
arguments. (#96)
+ Added string_view::contains methods that were introduced in C++23. (#93
)
+ In string_view, added asserts in remove_prefix/remove_suffix methods to
enforce the precondition that the prefix/suffix length does not exceed
the string view size. The previous (undocumented) behavior of silently
clamping the prefix/suffix length is deprecated and will be removed in
a future release. (#92)
* Wave: Fixed bugs:
+ #24: Line numbers wrong after conditional section
+ #160: one test fails with error C2660 and error C2440 under msvc /
permissive- mode
+ #161: BOOST_WAVE_THROW_NAME_CTX does not result in a context callback
and always throws
+ #162: When Boost headers are included in the preprocessed translation
unit, Wave fails in boost/integer.hpp(99)

+ Fixed experimental::coro's per-operation cancellation.
+ Fixed memory management in experimental::promise's type-erased
completion handlers.
+ Fixed move operator= implementation for ssl::stream.
+ Fixed any_io_executor implementation to work when both
BOOST_ASIO_USE_TS_EXECUTOR_AS_DEFAULT and
BOOST_ASIO_SEPARATE_COMPILATION are defined.
+ Fixed implementation of basic_socket::at_mark() when using the
sockatmark() system call.
+ Changed the recycling allocator to use the default alignment as the
minimum alignment for allocations.

clang.
+ On Windows, changed the file support to open files using the same
sharing mode as fopen().
+ On Linux, fixed UNIX domain sockets implementation to correctly handle
EAGAIN.

through the executor in some circumstances.
+ Fixed various header inclusion issues.
+ Fixed various warnings.
+ A number of documentation enhancements, including:
o Added an overview of Asio's asynchronous model.
o Reworked reference and requirements documentation in terms of
asynchronous model.
o Updated documentation for dispatch(), post(), and defer().
o Documented per-operation cancellation for serial ports.
o Clarified the non-concurrency guarantees made for allocators.
o Reverted the io_context reference documentation to use
executor_work_guard.
o Added more detailed reference documentation to make_strand(),
make_work_guard(), ip::address_v4, ip::address_v6, experimental::
basic_channel, and experimental::basic_concurrent_channel.
o Re-arranged and extended the Overview documentation to cover
recently added features.
+ Added a C++11 example showing file descriptor passing over local
sockets.
+ Added C++14 examples of wrapping callback-based APIs in asynchronous
operations.
+ Consult the Revision History for further details.
* Assert:
+ source_location().file_name() and source_location().function_name() now
return "" instead of "(unknown)".
+ Added a source_location constructor from std::source_location.
+ Changed BOOST_CURRENT_LOCATION to more closely match the behavior of
std::source_location::current(), such as being usable at top level or
as a default function argument.
* Atomic:
+ Fixed compilation for Universal Windows Platform (UWP). (#54)
+ Added BOOST_ATOMIC_NO_DARWIN_ULOCK configuration macro. The macro
affects compilation on Darwin systems and disables ulock-based
implementation of waiting and notifying operations. This may be useful
to comply with Apple App Store requirements. (#55)

entry to the Companies and Individuals Using Beast list.
+ See the full Release Notes for a complete list of changes.
* Core:
+ Made boost::pointer_traits SFINAE friendly, addressing LWG3545. (Glen
Fernandes)
+ Added boost::allocator_traits that uses the individual allocator access
traits. This implementation supports C++03 and above. (Glen Fernandes)
+ Updated the allocator access traits to support most of the C++11
allocator model in C++03. (Glen Fernandes)
+ boost/iterator.hpp is deprecated and will be removed in a future
release. The header defines boost::iterator template, which is
equivalent to std::iterator in <iterator> header. However, since std::
iterator is itself deprecated in C++17, users are advised to remove
boost::iterator or std::iterator use from their code.
+ Added boost::core::verbose_terminate_handler, a utility function
intended to be passed to std::set_terminate that prints information
about the uncaught exception to stderr.
* Describe:
+ Enabled unions in BOOST_DESCRIBE_STRUCT and updated examples to check
std::is_union<T>.
+ Added example of defining a fmtlib class formatter.
+ Added example of defining a fmtlib enum formatter.
+ Added example of printing pointers to members.
* Filesystem:
+ v3: path::replace_extension now works in terms of v3 definition of path
::extension rather than v4.
+ Fixed compilation of path appending and concatenation operators with
arguments of types convertible to path or compatible string type. (#223
)
+ On POSIX systems that support fdopendir and O_NOFOLLOW and on Windows,
remove_all is now protected against CVE-2022-21658. The vulnerability
is a race condition that allows a third party process to replace a
directory that is being concurrently processed by remove_all with a
directory symlink and cause remove_all to follow the symlink and remove
files in the linked directory instead of removing the symlink itself. (
#224)
+ On Windows, in remove and remove_all implementation, use POSIX
semantics for file removal, when supported by the OS (Windows 10 1709
and later). When POSIX semantics is supported, the file name is removed
from the filesystem namespace as soon as the file is marked for
deletion, even if it is still open and in use. With legacy Windows
semantics, the file name remains present in the the filesystem
namespace until the last file handle to the file is closed, which
allows the file marked for deletion to be opened and prevents creating
new files with the same name. (#216)
+ On Windows, remove and remove_all now support deleting read-only
directories. Support for removing read-only non-directory files was
added previously.
+ On Windows, directory_iterator internal implementation has been
reworked to better utilize modern Windows APIs, which may improve
performance while handling symlinks.
+ On Windows, initialize internal WinAPI function pointers early, if
possible, to allow Boost.Filesystem operations to be invoked in global
constructors. This is only supported on MSVC, GCC, Clang and compatible
compilers.
+ On Windows, resize_file should no longer fail with an error if the file
to be resized is opened.
+ Disabled use of the statx syscall on Android prior to 11.0 (API version
30). The syscall is blacklisted by seccomp and causes process
termination in runtime. (#229)
+ Deprecated: boost/filesystem/string_file.hpp header is deprecated and
will be removed in a future release. The header is no longer included
by boost/filesystem.hpp by default. Users are advised to implement the
functionality themselves or migrate to other implementations.
+ Deprecated: Windows CE support is deprecated and will be removed in a
future release. Windows CE has been untested for many years and is
likely non-functional.
* Geometry:
+ Major change
o PR#977 Rescaling is turned off by default. This avoids many related
bugs in set operations and buffer.
+ Improvements
o PR#923 Added algorithm closest_points for cartesian point/geometry.
o PR#939 Added algorithm closest_points for other coordinate systems
and geometry combinations excl. boxes.
o PR#961 Added Web Mercator projection.
o PR#966 More efficient cartesian distance strategy used in simplify.
+ Solved issues
o #956 Result of simplify algorithm with incorrect closure.
o #962 Runtime error in R-tree deserialization due to load factor.
o #971 R-tree insertion time impacted by use of long double on ARM
platforms.
+ Bugfixes
o PR#936 Envelope of polygon containing pole.
o PR#948 Spherical and geographic envelope for near meridian
segments.
o PR#974 Spheroidal normalization utilities for NaN coordinates.
o Various fixes in set operations and buffer.
* Integer:
+ Optimized integer_log2 implementation to use bit operations internally.
This allows to employ bit instructions available on most modern CPUs. (
#31)
* IO:
+ Added boost::io::basic_nullbuf, a null stream buffer, and boost::
basic_onullstream, a null output stream (Glen Fernandes).
* Iterator:
+ In counting_iterator, added support for built-in 128-bit integer types
supported by gcc and clang and compatible compilers on some target
platforms.
+ Silenced gcc warnings about deprecated implicit copy assignment
operator in counting_iterator.
* JSON:
+ Standalone mode of the library is removed. Users who wish to continue
using standalone JSON can switch to the C++ Alliance fork.
+ Add std::error_code overloads.
+ Add boost::source_location to error_codes.
+ Add support for JSON Pointer.
+ Naturally grow string during serialization.
* LEAF:
+ Support for FreeRTOS and other embedded platforms
+ Improved diagnostic information
+ Improved configuration macros
+ BOOST_LEAF_CHECK using statement expressions under __GNUC__
+ Fixed symbol demangling bug
* Log:
+ General changes:
o In text_file_backend, added support for appending to a previously
written log file, when file rotation is used and log file names use
file counters.
o Breaking change: The file_collector interface has changed:
# scan_for_files method returns a scan_result structure that
contains information collected during the scan;
# is_in_storage method added for testing if a path refers to a
file within the target storage directory.
o Added a new invoke_manip stream manipulator that can be used for
injecting user's function into a stream output expression.
+ Bug fixes:
o Fixed file counter being set to zero if the user calls
text_file_backend::scan_for_files multiple times, and the second
and the following calls don't find any new files. (#179)
+ See changelog for more details.
* Multi-index Containers:
+ Improved the efficiency of count operations in ranked indices from O(
log(n) + count) to O(log(n)). Contributed by Damian Sawicki.
+ Maintenance work.
* Nowide:
+ Fix compilation issues on some platforms (e.g. GCC 11 on MinGW-w64 and
Cygwin)
+ Fix missing include when using BOOST_USE_WINDOWS_H and
WIN32_LEAN_AND_MEAN
+ Add sanity check when using boost::nowide::stat with boost::nowide::
stat_t
* Optional:
+ Fixed issue #98.
+ Fixed issue #92.
+ Added support for BOOST_NO_IOSTREAM.
+ Now aligned storage uses unsigned char rather than char to avoid UB.
+ Now using cv-unqualified value_type with placement new to avoid UB.
* Predef:
+ Version 1.14.0
+ Add detection of LoongArch (from Zhang Na).
* QVM:
+ Added constexpr under C++17
+ Improved single header distribution
* Smart Pointers:
+ Added boost::get_allocator_pointer to obtain the Allocator pointer from
the result of boost::allocate_unique (Glen Fernandes).
* System:
+ Added a boost::source_location parameter to throw_exception_from_error.
+ Added throw_exception_from_error overloads for errc::errc_t, std::
error_code, std::errc, std::exception_ptr.
+ result<T>::value now automatically supplies BOOST_CURRENT_LOCATION to
throw_exception_from_error via a default argument.
+ Added an errc::make_error_code overload taking a source location.
* ThrowException:
+ Added boost::throw_with_location, a more lightweight alternative of
BOOST_THROW_EXCEPTION for programs that do not use Boost.Exception.
* Unordered:
+ All containers have been updated to support heterogeneous count,
equal_range and find.
+ All containers now implement the member function contains.
+ erase_if has been implemented for all containers.
+ All containers have been updated to support heterogeneous erase and
extract.
+ Changed behavior of reserve to eagerly allocate.
+ Various warning fixes in the test suite.
+ Update code to internally use boost::allocator_traits.
+ Switch to Fibonacci hashing.
+ Update documentation to be written in AsciiDoc instead of QuickBook.
* Variant2:
+ Added operator<< for monostate.
* Wave:
+ C++11 now required for building Wave itself
+ Fixed bugs:
o #135: Comma operators in array subscripts are deprecated in C++20
o #137: Simple unknown directive => found_unknown_directive is not
called, stripped of pound.
o #138: Empty ifdef block does not emit line directive for missing
whitespace

o #145: Sanitizer complains about reset_version()
o #147: bitwise operations between different enumeration types are
deprecated

Log message:
boost: Update to 1.78.0
Changelog:
Version 1.78.0
Known Issues
These are patches from library authors which were found too late to be fixed in
the release.
* Boost.Build silently skips installation of library headers and binaries in
some cases, see #104.
+ Fixed in PR#113, patch.
* Boost.Atomic fails to build when targeting UWP, see #54. Patch.
New Libraries
* No new libraries.
Updated Libraries
* Asio:
+ Added an io_uring backend that may optionally be used for all I/O
objects, including sockets, timers, and posix descriptors.
+ Added support for files, with new new classes for stream-oriented and
random-access files. This feature currently supports I/O completion
ports on Windows, and io_uring on Linux.
+ Added support for portable pipes on POSIX and Windows (when I/O
completion ports are available).
+ Added support for registered buffers, which are optimised when using
the io_uring backend.
+ Added experimental support for channels, that may be used to send and
queue completions as messages.
+ Implemented improvements to experimental::coro.
+ Disabled aligned_alloc on clang when using an MSVC runtime.
+ Changed to use a faster implementation for ip::network_v4::canonical().
+ Added template specialisations for common uses to improve compile time.
+ Reduced the size of io_context executors to a single pointer.
+ Increased the small object buffer size for execution::any_executor and
any_io_executor.
+ Fixed multi-signature handling when variadic templates are disabled.
+ Fixed compatibility with new versions of gcc and clang.
+ Fixed compilation on Solaris.
+ Fixed defence against Qt-defined macros when building with MSVC.
+ Improved error messages emitted by ssl facilities.
+ Fixed bind_executor compatibility with completion tokens.
+ Fixed build errors when BOOST_ASIO_USE_TS_EXECUTOR_AS_DEFAULT is
defined.
+ Added missing move assignment operator to awaitable<>.
+ Fixed an access violation when using coroutines with MSVC, due to
incorrect alignment of allocated memory.
+ Fixed a cleanup issue in experimental::parallel_group that occured when
the execution context was shut down with parallel operations still
pending.
+ Added clarifications to the documentation on concurrency hints.
+ Added documentation on error handling techniques for C++20 coroutines.
+ Fixed various warnings.
+ Consult the Revision History for further details.
* Assert:
+ Added source_location::to_string.
* Atomic:
+ Use process-local futex operations on Android for non-IPC waiting and
notifying operations.
+ Added support for Linux targets that only define SYS_futex_time64
syscall, such as riscv32.
+ Added a workaround for incorrect result of std::alignment_of on clang 8
for 64-bit types on 32-bit x86 targets.
+ Added a ulock backend for waiting and notifying operations on Darwin
systems since Mac OS 10.12, iOS 10.0, tvOS 10.0 or watchOS 3.0.
+ On Windows, corrected discrepancy between atomic-type
::always_has_native_wait_notify and the corresponding capability macros
when targeting Windows 8 or later. The library will now directly use
WaitOnAddress and related APIs from public headers and therefore
require user to link with synchronization.lib if the user requires
Windows 8 or later by defining BOOST_USE_WINAPI_VERSION, _WIN32_WINNT
or similar macros. The library is linked automatically on compilers
that support auto-linking (e.g. MSVC).
+ Added support for types with padding bits, except unions, on compilers
that provide a way to clear the padding bits. This feature is supported
by gcc 11 and MSVC 14.2 (compiler version 19.27) and newer, as well as
other compilers supporting similar intrinsics. On compilers that don't
allow to clear the padding bits, types with padding are still generally
not supported with the exception of 80-bit long double on x86 targets.
A new BOOST_ATOMIC_NO_CLEAR_PADDING capability macro is defined to
indicate when clearing the padding is not supported.
+ Initializing constructors of atomic_ref and ipc_atomic_ref no longer
use atomic instructions to clear the padding bits in the referenced
object. This reduces the cost of the atomic reference construction.
+ Initializing constructors of atomic and ipc_atomic are now constexpr
for enums, classes and floating point types. For classes and floating
point types, the constructors are constexpr if the compiler supports
constexpr std::bit_cast, the type has no padding bytes and no padding
is required to implement native atomic operations.
+ In accordance with C++20, default constructors of atomic and ipc_atomic
now perform value initialization of the contained object. For types
without a user-defined default constructor, this means the
default-constructed atomic will be zero-initialized.
+ Added a workaround for compilation error on AIX caused by the assembler
tool not supporting numeric labels. (PR#50)
+ Added a workaround for compilation error with Visual Studio 2015 prior
to Update 3. (#52)
+ See changelog for more details.
* Beast:
+ This maintenance update brings minor bug fixes and updated CI
reporting.
+ Fixed security vulnerability CVE-2016-9840 in zlib implementation.
+ Fixed WebSocket permessage_deflate implementation. This should result
in an increase in compression performance when using Beast WebSockets.
+ Removed the test stream and test framework's dependency on RTTI. You
can now use our handy test stream to check your embedded asynchronous
communications code!
+ We'd love to know how you or your company use Beast, consider adding an
entry to the Companies and Individuals Using Beast list.
+ See the full Release Notes for a complete list of changes.
* Core:
+ Added a generic implementation to <boost/core/cmath.hpp>, enabled when
BOOST_CORE_USE_GENERIC_CMATH is defined or when the platform does not
provide the necessary facilities in <cmath>.
+ Added boost::core::type_name, a utility function that returns the name
of a type as a string.
+ Added boost::span, a C++11 implementation of C++20's std::span (Glen
Fernandes).
* Describe:
+ Added has_describe_enumerators, has_describe_bases,
has_describe_members.
+ Added enum_to_string, enum_from_string.
+ Added relational and stream insertion operators.
+ Added descriptor_by_name, descriptor_by_pointer.
* DLL:
+ Fixed missing #include, thanks to Denis Blank (PR#54)
+ Dropped TravisCI in favor of GithubAction CI
* Filesystem:
+ v4: path::filename and path::iterator no longer return an implicit
trailing dot (".") element if the path ends with a directory \
separator.
Instead, an empty path is returned, similar to C++17 std::filesystem.
This also affects other methods that are defined in terms of iterators
or filename, such as path::stem, path::compare or
lexicographical_compare. For example, path("a/b/") == \
path("a/b/.") no
longer holds true. (#193)
+ v4: path::lexically_normal no longer produce a trailing dot (".")
element and omits a directory separator after a trailing dot-dot \
("..")
element in the normalized paths.
+ v4: path append operations now consider root name and root directory in
the appended path. If the appended path is absolute, or root name is
present and differs from the source path, the resulting path is
equivalent to the appended path. If root directory is present, the
result is the root directory and relative path rebased on top of the
root name of the source path. Otherwise, the behavior is similar to v3.
(#214)
+ path::lexically_normal now converts directory separators to preferred
separators in the root name of the normalized paths.
+ Optimized overloads of path::assign, path::append, path::concat and the
corresponding operators to avoid unnecessary path copying and reduce
the amount of code redundancy.
+ On POSIX systems, fixed absolute(p, base) returning a path with root
name base.root_name() if p starts with a root directory. In such a case
p is already an absolute path and should be returned as is.
+ create_directories no longer reports an error if the input path
consists entirely of dot (".") and dot-dot ("..") \
elements. The
implementation is no longer using recursion internally and therefore is
better protected from stack overflow on extremely long paths.
+ On Windows, remove now supports deleting read-only files. The operation
will attempt to reset the read-only attribute prior to removal. Note
that this introduces a possibility of the read-only attribute being
left unset, if the operation fails and the original value of the
attribute fails to be restored. This also affects remove_all. (#216)
+ remove_all now returns static_cast< uintmax_t >(-1) in case of error,
similar to C++17 std::filesystem.
+ Fixed a linking error about unresolved references to
Boost.ContainerHash functions when user's code includes boost/
filesystem/path.hpp but not boost/container_hash/hash.hpp and the
compiler is set to preserve unused inline functions. (#215)
+ Added a workaround for MSVC and compatible compilers eliminating path
globals cleanup in release builds. This could lead to a memory leak if
Boost.Filesystem shared library was repeatedly loaded and unloaded in
the process. (#217)
* Geometry:
+ Improvements
o PR#894 Optimization and refactoring of rtree queries.
o PR#913 DynamicGeometry and GeometryCollection support in various
algorithms (undocumented for now).
o PR#922 DynamicGeometry and GeometryCollection support in distance
(undocumented for now).
+ Solved issues
o #867 Poor performance of rtree query iterator with nearest
predicate for big k.
o #870 Compilation error in boost::geometry::self_turns.
o #896 Assertion failure in get_turns with
BOOST_GEOMETRY_NO_ROBUSTNESS.
+ Bugfixes
o PR#906 Invalid result of buffer on macos-11 with clang-12.
o PR#921 Compilation errors with c++20 (various compilers) and gcc-5.
o Various fixes in set operations and buffer.
* JSON:
+ Standalone mode of the library is deprecated.
+ Allow external libraries to forward declare value_to and value_from.
+ Fixed signed integer overflow in number parsing.
+ Add support for /Zc:implicitNoexcept- on MSVC.
* Lambda2:
+ Added special cases in operator<< and operator>> when the first
argument is a stream, to allow std::cout << _1.
+ Added operator->*.
+ Added first, second.
* Log:
+ General changes:
o Updated detection of std::codecvt specializations for char16_t and
char32_t for compatibility with C++17 and later. (PR#159)
o Added support for C++17 std::byte type to receive methods of the
inter-process message queue.
o On Windows, when building the library for Windows 8 or later, the
library will use nt62 tag in the version namespace to denote the
target OS ABI. For example, the version namespace could be named as
v2_mt_nt62. This name will be part of all symbols exported by the
library. Use the BOOST_USE_WINAPI_VERSION macro consistenly when
building Boost and your code to request the minimum target Windows
version.
o Improved performance of SSSE3 and AVX2 implementations of the dump
stream manipulator.
o Added support for CMake build system. Only library build is
supported at this moment, Boost.Build is still used for running
tests.
+ Bug fixes:
o Fixed a race condition on POSIX systems in reliable_message_queue::
open_or_create or the equivalent constructor. Multiple threads or
processes calling open_or_create concurrently with sending or
receiving messages from the same queue could end up corrupting the
queue contents and potentially crashing the process. (#162)
o Added a workaround for b2 install failing on Windows because of
missing boost_log_setup library if
BOOST_LOG_WITHOUT_SETTINGS_PARSERS is defined. (#164)
+ See changelog for more details.
* Math:
+ Add support for cubic roots.
+ Add support for constexpr versions of various standard library math
routines.
+ Add support for Bezier polynomials.
+ Improve worst-case tanh-sinh integration performance.
+ Disable inadvertant use of integral types in integration routines.
+ Minor update for erf approximations when the result is with 2ulp of 1.
+ Allow Bernoulli code to be used on platforms with no atomic integers.
+ Improve the mode of the non-central Chi Squared distribution.
+ Improve certain edge cases for <cstdfloat> complex-valued elementary
functions, see #507.
* Multi-index Containers:
+ Added contains to key-based indices (issue #35).
+ Added merge operations to key-based indices. The functionality goes
beyond the standard specification for (unordered) associative
containers in a number of ways, most notably:
o The source index can be of any type, including non key-based
indices.
o Partial merge is provided: for instance, x.merge(y,first,last)
merges only the elements of y within [first,last).
+ Previous versions of splice for sequenced and random access indices
were destructive, i.e. elements were copy-inserted into the destination
and then erased from the source. Now, splice is based on node transfer
much as merge in key-based indices, and has been similarly extended to
accept source indices of any type: in fact, splice can be regarded as a
frontend to the same functionality provided by merge in key-based
indices. For reasons of backwards compatibility, the destructive
behavior of splice has been retained in the case that the source and
destination containers have unequal allocators.
+ The fact has been documented that index iterator types do only depend
on node_type and the position of the index in its multi_index_container
, (except for hashed indices, where uniqueness/non-uniqueness is also a
dependency). This has implications on the validity of iterators to
elements transferred by merge or splice. This property is a variant of
what has been called SCARY iterators in the C++ standard mailing lists.
SCARYness is currently (August 2021) not mandated for standard
containers.
+ Iterator SCARYness is now also preserved in safe mode.
* Multiprecision:
+ Rework rational_adaptor to remove dependency on Boost.Rational and
improve performance.
+ Fix issue with type_traits and clang, see #383.
+ Fixed buggy Lehmer's GCD routine, see #370.
+ Fix mpc_complex constructors so that lossy conversions are explicit,
see #363.
+ Correct miscellaneous configuration issues (Intel intrinsic usage and
Apple clang).
+ Correct some iostream operators for unsigned char types.
+ Correct mpq_rational conversions to integer types, see #342.
* PFR:
+ Added missing #include <memory> for inclusion of std::addressof
+ Fixed -Wzero-length-array warning when dealing with empty aggregates

behaviour.
+ Change w32_regex_traits.hpp so that windows.h is no longer included.
+ Fxed fuzzing related issues #151, #152, #153, #156.
* System:
+ Added support for source locations to error_code.
+ Added error_code::to_string, error_condition::to_string, error_code::
what.
+ system_error::what() now contains the source location, if present.
+ Added result<T, E = error_code>, a class holding either a value or an
error, defined in <boost/system/result.hpp>.
* Utility:
+ Library documentation converted to QuickBook (thanks to Alan de
Freitas, PR#79).
* Variant2:

Log message:
boost: updated to 1.77.0
1.77.0
New Libraries
Describe:
A C++14 reflection library, from Peter Dimov. Provides macros for describing \
enumerators and struct/class members, and primitives for querying this \
information.
Lambda2:
A C++14, dependency-free, single header lambda library, from Peter Dimov. Allows \
simple function objects to be constructed via expressions such as _1 + 5, _1 % 2 \
== 0, _1 > _2, or _1 == ' ' || _1 == '\t'.
Updated Libraries
Any:
Added boost::anys::basic_any - a data type with customizable Small Object \
Optimization whose instances can hold instances of any type that satisfies \
ValueType requirements (many thanks to Ruslan Arutyunyan @rarutyun). If you are \
not sure that you really need it, then use boost::any instead.
Started using GithubActions CI for additional testing
Asio:
Added support for cancellation of individual asynchronous operations.
Added the associator trait, used to generically forward associators.
Changed all asynchronous operations implemented in Asio to invoke their \
completion handlers as rvalue references.
Added support for asynchronous operations with multiple completion signatures.
Added operator&& and operator|| for awaitable<>, to allow \
coroutines to be trivially awaited in parallel.
Added the experimental::as_tuple completion token adapter.
Added the experimental::append completion token adapter.
Added the experimental::prepend completion token adapter.
Added the experimental::deferred completion token, whicih allows deferred \
execution of asynchronous operations.
Added the experimental::parallel_group class and \
experimental::make_parallel_group function.
Added experimental::promise, which allows eager execution and synchronisation of \
asynchronous operations.
Added the experimental::coro class template, a C++20 coroutine primitive with \
the ability to combine both asynchronous waiting (co_await) and yielding \
(co_yield).
Added move assignment to ssl::stream<>.
Changed co_spawn to dispatch the coroutine's initial step to the executor.
Enabled additional optimisations for any_executor and any_io_executor when used \
with asynchronous operations.
Added the nodiscard attribute to awaitable<>.
Increased the number of cached slots in the default recycling allocator.
Changed the default allocator behaviour to respect alignment requirements, to \
support over-aligned types.
Ensured the result strings are always initialised in reverse name resolution.
Fixed recursive template instantiation issues in \
use_awaitable_t::executor_with_default.
Fixed the any_io_executor equality operators to correctly return a result based \
on the target executor.
Fixed strand<> to avoid using a potentially moved-from executor.
Ensured gcc tests are not used for clang when detecting compiler features.
Disabled coroutines support for the clang shipped with MSVC.
Fixed compatibility with recent LibreSSL when OPENSSL_NO_SSL_INTERN is defined.
Fixed posix::basic_stream_descriptor move operations to work with non-defaulted \
executors.
Consult the Revision History for further details.
Atomic:
Added make_atomic_ref and make_ipc_atomic_ref factory functions for constructing \
atomic reference objects.
Added C++17 template argument deduction guides for atomic_ref and ipc_atomic_ref \
to allow omitting template arguments when they can be deduced from constructor \
arguments.
Beast:
This maintenance update brings minor bug fixes and updated CI reporting.
We'd love to know how you or your company use Beast, consider adding an entry to \
the Companies and Individuals Using Beast list.
See the full Release Notes for a complete list of changes.
Conversion:
boost::implicit_cast is now constexpr.
Fixed broken links.
Started using GithubActions CI for additional testing
Core:
boost/core/uncaught_exceptions.hpp has been modified for compatibility with Mac \
OS 10.4 and older.
DLL:
More runtime checks for malformed ELFs in boost::dll::library_info
In boost::dll::library_info use info from .dynsym ELF section if .symtab is \
empty or missing
List protected ELF symbols in boost::dll::library_info as they are available for \
import
Remove unneeded convert from wchar_t to char on POSIX environment, thanks to \
Vladislav Shchapov
Started using GithubAction CI for additional testing
Filesystem:
Introducing Boost.Filesystem v4. This new version of the library removes all \
deprecated features of v3 and also makes a number of breaking API changes \
intended to make Boost.Filesystem more compatible with std::filesystem \
introduced in C++17. The differences are described in the release notes and \
documentation using v3 and v4 tags and are also summarised in a separate \
section. Users can select Boost.Filesystem version by defining \
BOOST_FILESYSTEM_VERSION macro to either 3 or 4 when compiling their code. There \
is no need to separately compile Boost.Filesystem for each library version - a \
single binary supports both v3 and v4. Users should avoid using both v3 and v4 \
in the same application as this can lead to subtle bugs. Currently, v3 is the \
default. In a future release v4 will become the default, and eventually v3 will \
be removed. v4 is functional, but it is still a work in progress and there may \
be breaking API changes in the future.
v4: path::filename, path::stem and path::extension no longer consider root name \
or root directory of the path as a filename if the path only consists of those \
components. For example, on Windows path("C:").filename() used to \
return "C:" and path("C:\\").filename() used to return \
"\" and both will return an empty path now.
v4: path::stem and path::extension no longer treat a filename that starts with a \
dot and has no other dots as an extension. Filenames starting with a dot are \
commonly treated as filenames with an empty extension. The leading dot is used \
to indicate a hidden file on most UNIX-like systems.
New: Improved support for various path prefixes on Windows. Added support for \
local device prefix ("\\.\") and experimental support for NT path \
prefix ("\??\"). The prefixes will be included in the root name of a \
path. Note that using the prefixes with Boost.Filesystem v3 can lead to \
surprising results (e.g. path("\\\\.\\").stem() == "\\\\"). \
It is recommended to use the prefixes only with Boost.Filesystem v4.
Reworked path::lexically_normal implementation to eliminate some cases of \
duplicate dot (".") elements in the normalized paths.
New: Added runtime detection of the statx and getrandom system calls on Linux. \
This can be useful if the syscall is present at compile time but fails with \
ENOSYS at run time (for example, in Docker containers that restrict the syscall, \
even if available on the host).
New: Added support for disabling usage of various system APIs at library build \
time. This can be useful when a certain API is detected as present by the \
library configuration scripts but must not be used for some reason (for example, \
when runtime detection does not work on the target system). See the description \
of configuration macros in the library documentationfor for more details.
New: Added copy_options::synchronize_data and copy_options::synchronize options \
for the copy_file operation. These options allow to synchronize the written data \
and attributes with the permanent storage. These options are expensive in terms \
of performance, but allow to ensure reliability of the copied data. Note that \
copy_file performed implicit data synchronization on POSIX systems since \
Boost.Filesystem 1.74.0. This release adds support for more platforms and \
disables data synchronization by default while allowing the caller to explicitly \
request it.
Added handling of EINTR error code on POSIX systems for some system calls issued \
internally. In particular, EINTR could have been ignored on close, which on \
HP-UX would result in a leaked file descriptor.
In the copy_file implementations based on Linux sendfile and copy_file_range \
system calls, added handling of error codes indicating that a particular \
filesystem does not support the system call and fall back to the generic \
read/write loop. This should fix copy_file failing on eCryptFS and possibly \
other filesystems.
The copy_file_range system call is now used since Linux kernel 4.5, whereas \
previously it was only enabled since 5.3. The copy_file implementation will fall \
back to sendfile or read/write loop if copy_file_range fails to copy a given \
file across filesystems.
The copy_file implementations based on Linux sendfile and copy_file_range system \
calls will not be used on filesystems that are known to contain files with \
generated content. These system calls are incompatible with such files, and \
copying them would result in zero-sized files. The generic read/write loop will \
be used instead. Currently, the blacklisted filesystems are: procfs, sysfs, \
tracefs and debugfs.
In the copy_file implementation based on read/write loop, increased the maximum \
size of the buffer used for temporary storage and take into account the target \
filesystem block size for more optimal performance.
On Windows CE, calling current_path to obtain the current path for a process \
will now fail with an error instead of returning successfully with a root path. \
This platform does not support current directory. Changing the current path was \
already failing similarly in previous releases of Boost.Filesystem.
In canonical, fixed the check for a symlink referencing a directory above root, \
if an earlier symlink was resolved to an absolute path with a different root \
from the original path.
In canonical, added a limit for the maximum number of symlinks that can be \
resolved during the call. The limit is currently at least 40 symlinks.
On Windows, canonical and weakly_canonical will now use \
path::preferred_separator for the root directory separator in the resulting \
paths. This fixes "file not found" errors caused by Windows API not \
handling generic separators in UNC paths and paths that start with the Win32 \
filesystem prefix ("\\?\").
New: Added weakly_canonical overloads taking base path as an argument.
On Windows, weakly_canonical no longer fails with an error if the input path \
contains elements that do not exist in the filesystem but are cancelled by a \
subsequent dot-dot ("..") element. For example, \
weakly_canonical("C:\\a\\..") would previously fail if \
"C:\a" directory did not exist.
In read_symlink on Windows, corrected reparse point handling. The operation \
would return an empty path for some mount points (for example, created by Box \
cloud storage driver) and directory junction points that had empty print names. \
The new implementation now parses substitute name of the reparse point and \
attempts to reconstruct a Win32 path from it.
On Windows, file streams provided in boost/filesystem/fstream.hpp will use wide \
character paths on libc++ versions 7.0 and higher, when the standard library \
supports opening files with wide character paths.
On Windows, creating symlinks should no longer require elevated privileges, if \
Windows is configured in Developer mode.
With some compilers, global objects used internally in Boost.Filesystem are now \
destroyed after user's global destructors are called. This allows to call \
Boost.Filesystem methods during the program termination stage. In particular, \
this concerns the path locale that is used for character code conversion and can \
be installed by calling path::imbue. The supported compilers include MSVC, GCC \
and Clang, as well as other compilers that support customizing program \
initialization order through #pragma section (for MSVC-compatible compilers) or \
__attribute__ ((init_priority)) (for GCC-compatible compilers).
JSON:
value_to supports TupleLike types.
value_to and value_from support std::array and similar types.
Implicit conversion operator from string to std::string_view.
std::hash specializations for json types.
Fixed allocation errors in object and key_value_pair.
Fixed crash when constructing array from a pair of iterators that form an empty \
range.
LexicalCast:
Fixed assignment to an int of a floating point value that is out of \
representable range for int.
Started using GithubActions CI for additional testing
Log:
Fixed compilation for riscv32 target.
Mp11:
Added mp_intersperse, mp_split, mp_join
Multi-index Containers:
Maintenance work.
PFR:
A MurMur Hash based implementation of hash_combine() is now used to reduce \
collisions count and improve quality of boost::pfr::hash_value()
Visual Studio 2017 now supported in C++14 mode (thanks to Denis Mikhailov aka \
@denzor200)
Issues found by inspect tool were fixed
Fixed some warnings, including removal of extra semicolons in \
include/boost/pfr/detail/fields_count.hpp
Added a compile time assert for inherited types (thanks to Denis Mikhailov aka \
@denzor200)
Reflection of aggregates with non movable fields is now possible if guaranteed \
copy elision is on
Fixed spelling issues
Started using GithubActions CI for additional testing
PropertyTree:
This is a maintenance release.
Extend compiler coverage in CI.
Fix Boost compatibility for CMakeLists.txt.
System:
The conversion operator from error_category to std::error_category has been \
improved and no longer requires <map> or <mutex>.
The comparison operators of error_category are now inline friends instead of \
member functions (a side effect of the previous change.)
error_condition now defers calling generic_category() to avoid instantiating the \
object until it's actually needed.
error_condition::failed and error_condition::message have been undeprecated, and \
operator bool() now once again returns failed().
The system category now doesn't call generic_category(), to avoid instantiating \
the object.
The return value of default_error_condition changes in some cases into an \
error_condition from the generic category, instead of from the system category. \
This happens on POSIX when the input error_code is from the system category and \
does not correspond to any errc_t value.
The interoperability of error_code and std::error_code has been improved \
substantially. It is now possible to construct boost::system::error_code from \
std::error_code, and it's possible to pass boost::system::error_code to \
functions taking std::error_code&.
A stream insertion operator for error_condition has been added.
Uuid:
Added to_chars for writing uuid strings without allocating

Update boost::apply to use variadic templates and perfect forwarding.
Container:
Added [[no-discard]] attribute in all containers to catch bugs related to unused \
return values.
Replaced default standard exception classes with Boost.Container own classes, \
reducing considerably the included files overhead. Example: in MSVC 19 \
boost/container/vector.hpp preprocessed file size reduces from 1,5MB to 930KB. \
If you still want to use standard exception classes, you can define \
BOOST_CONTAINER_USE_STD_EXCEPTIONS before using any Boost.Container class.
Fixed bugs/issues:
GitHub 102: "flat_map::insert ambiguous with initializer list & pairs \
that need to convert".
GitHub 139: "flat_map merge and iterators".
GitHub 141: "small_vector does not propagate no throw properties of move \
operation of contained type".
GitHub 164: "Compile error when using pmr::map with a std::pair; works when \
using a std::tuple".
GitHub 171: "deque::clear() uses undefined behaviour".
Core:
Add implicit conversion between compatible reference wrappers.
Add boost/core/cmath.hpp, a portable implementation of the floating point \
classification functions from <cmath>.
Add boost/core/bit.hpp, a portable implementation of the C++20 standard header \
<bit>.
Fix BOOST_TEST_EQ, BOOST_TEST_NE for character types under C++20.
Revise allocator access utilities (now support VS2013, and no workarounds use \
allocator_traits.)
DLL:
BREAKING CHANGE: boost::dll::import was renamed to boost::dll::import_symbol to \
avoid collision with C++20 import keyword.
Updated docs, including FAQ section.
Filesystem:
Updated compatibility with WASI platform.
Fixed an exception being thrown by path::remove_filename if the path is \
"////".
Fixed create_directories disregarding errors from file status query operations \
issued internally. This could result in incorrect error codes returned by \
create_directories.
GIL:
BREAKING: In next release, we are going to drop support for GCC 5. We will also \
change the required minimum C++ version from C++11 to C++14.
Intrusive:

linear_slist_algorithms use a simple node_ptr instead of std::pair on return.
list/slist use operator </operator == instead of std::equal_to/std::less.
Fixed GitHub 54: set.rbegin() looks like O(log(N))
Interprocess:
Added wchar_t API support for named resources in operating systems that offer \
native wide character API (e.g. Windows). The following classes were updated \
with wchar_t name support:

managed_shared_memory
managed_windows_shared_memory
shared_memory_object
windows_shared_memory_object
file_lock
named_condition
named_condition_any
named_mutex
named_recursive_mutex
named_semaphore
named_sharable_mutex
named_upgradable_mutex
message_queue
Added BOOST_INTERPROCESS_FORCE_NATIVE_EMULATION macro option to disable the use \
of generic emulation code for process shared synchronization primitives instead \
of native POSIX or Winapi functions.
Fixed bugs:
GitHub 76 ("Cygwin compilation errors").
GitHub 83 ("Add BOOST_INTERPROCESS_FORCE_NATIVE_EMULATION option").
GitHub 92 ("bufferstream: Correct MSVC compilation warning").
GitHub 106 ("Use fallocate on truncate_file").
GitHub 120 ("segment_manager customization").
GitHub 122 ("Mark constructors/assignment/swap noexcept where possible").
GitHub 126 ("_ReadWriteBarrier is deprecated warning when compiling with \
clang-cl.exe").
JSON:
Security Report from Bishop Fox.
Refactored value_from implementation; user customizations are now always \
preferred over library-provided overloads.
Fix imprecise parsing for some floating point numbers.
Fix link errors in standalone mode, when used alongside Boost.
Fix Boost.Build builds on GCC 4.8.
LexicalCast:
Dropped dependency on Boost.Math
Fixes for the CI and coverage
Log:
Bug fixes:
Corrected a formal race condition in the thread-safe log record queue \
implementation used in the unbounded_fifo_queue policy of the asynchronous_sink \
frontend. The race could be detected by TSAN, but it was not a real problem on \
most current CPU architectures and compilers.
When copying a logger with a channel attribute (e.g. channel_logger), the \
channel attribute is now deep-copied from the original logger. This means that \
modifying the channel in the new logger will no longer affect the original \
logger.
Replaced the use of std::allocator<void> in template parameters with a new \
tag type boost::log::use_std_allocator to silence libc++ warnings about the \
former being deprecated in C++17 and later. The tag indicates that the \
instantiated template should be using a specialization of std::allocator \
internally to allocate dynamic memory, so the change has no functional effect.
Boost.Log no longer defines __MSVCRT_VERSION__ macro on MinGW and MinGW-w64. \
Defining this macro caused incompatibility with UCRT, which is available as an \
option in recent MinGW-w64.
See changelog for more details.
Math:
Breaking Change: C++03 support is now removed, a C++11 or later conformant \
compiler is now required to use this library.
Added Z-test.
Added execution policy support to univariate and bivariate statistics: enables \
parallel execution (requires C++17 and <execution>).
Big update/improvement on CI testing.
Bivariate statistics now have integer support.
T-Test now has integer support.
Linear regression now has integer support.
Correct PDF of the beta distribution at the endpoints.
Correct use of Stirling's approximation in certain multiprecision cases.
Eliminate -Wimplicit-int-float-conversion on clang.
Fix some constexpr issues in quaternion/octonion.
Minor performance fix to tanh_sinh integration.
Update hypergeometric functions internal scaling to allow for 64-bit (long long) \
exponents with multiprecision types.
Move:
Git Issue 35: "New nothrow move traits are incomplete".
Multiprecision:
BREAKING CHANGE: Massive refactoring and code simplification makes C++11 an \
absolute requirement.
Use BOOST_TRY/CATCH in headers so code can be used in exception-free environments.
Correct corner case in pow.
Correct exception type thrown to match docs in lsb/msb.
Allow moves and operators between related but different types (ie types with the \
same allocator).
Nowide:
Fix discarding of characters for text file streams when seek or sync functions \
are used and newlines were converted (e.g. on Windows)
Fix potential use-after-free bug when reusing (via open) a file stream that has \
been closed
Fix potential invalid memory access when using a file stream that has been moved \
or swapped to where the source had a put-back character or was set to unbuffered \
mode
Fix compatibility with ucrt runtime by not defining __MSVCRT_VERSION__
Known issues: Read performance for text files is degraded. Binary files and \
writing is unaffected.
Optional:
Fixed MSVC warning C4702.
Outcome:
Announcements:
BREAKING CHANGE: After a year and three major Boost releases announcing this \
upcoming change, this is the FIRST RELEASE of the v2.2 branch. This branch has a \
number of major breaking changes to the Outcome v2.1 which shipped in Boost 1.75 \
and earlier, see the documentation for details.
Enhancements:
VS2019.8 changed how to enable Coroutines, which caused Outcome to not compile \
on that compiler.
If on C++ 20, we now use C++ 20 [[likely]] instead of compiler-specific markup \
to indicate when TRY has likely success or failure.
BREAKING CHANGE: Previously the value of spare_storage(const \
basic_result|basic_outcome *) noexcept was not propagated over \
BOOST_OUTCOME_TRY, which causes things like stack backtraces captured at the \
point of construction of an errored result to get dropped at every TRY point. \
This has been fixed by adding an optional spare_storage to success_type<T> \
and failure_type<T>, as well as to auto success(T &&, ...) and \
auto failure(T &&, ...).
Bug fixes:
Boost.Outcome should now compile with BOOST_NO_EXCEPTIONS defined. Thanks to \
Emil, maintainer of Boost.Exception, making a change for me, Boost.Outcome \
should now compile with C++ exceptions globally disabled. You won't be able to \
use boost::exception_ptr as it can't be included if C++ exceptions are globally \
disabled.
BREAKING CHANGE 244 It came as a shock to learn that BOOST_OUTCOME_TRY had been \
broken since the inception of this library for certain corner case code, which \
required a breaking change in how TRY works. See the changelog in the \
documentation for more detail.
Parameter:
Added a workaround for MSVC 2015 code miscompilation when an rvalue was used as \
a default value of a named parameter of a function.
PFR:
Fixed reflection of types with missing const in SFINAE expressions in template \
constructor. Now reflection of aggregates with \
std::optional<std::chrono::duration<???>> fields works on any \
Standard Library implementation, even if LWG3050 is not fixed.
Comparison functions are now constexpr
Fixed numerous typos in docs
