<span class="library"><a href="https://www.boost.org/doc/libs/1_78_0_beta1/libs/multi_index/">Multi-index Containers</a>:</span>
|
||
<ul>
|
||
<li>
|
||
<div>
|
||
Added <code><span class="identifier">contains</span></code> to
|
||
key-based indices (issue <a href="https://github.com/boostorg/multi_index/issues/35">#35</a>).
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Added <code><span class="identifier">merge</span></code> operations
|
||
to key-based indices. The functionality goes beyond the standard
|
||
specification for (unordered) associative containers in a number
|
||
of ways, most notably:
|
||
</div>
|
||
<ul>
|
||
<li>
|
||
<div>
|
||
The source index can be of any type, including non key-based
|
||
indices.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Partial merge is provided: for instance, <code><span class="identifier">x</span><span class="special">.</span><span class="identifier">merge</span><span class="special">(</span><span class="identifier">y</span><span class="special">,</span><span class="identifier">first</span><span class="special">,</span><span class="identifier">last</span><span class="special">)</span></code> merges only the elements of
|
||
<code><span class="identifier">y</span></code> within [<code><span class="identifier">first</span></code>,<code><span class="identifier">last</span></code>).
|
||
</div>
|
||
</li>
|
||
</ul>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Previous versions of <code><span class="identifier">splice</span></code>
|
||
for sequenced and random access indices were destructive, i.e. elements
|
||
were copy-inserted into the destination and then erased from the
|
||
source. Now, <code><span class="identifier">splice</span></code>
|
||
is based on node transfer much as <code><span class="identifier">merge</span></code>
|
||
in key-based indices, and has been similarly extended to accept source
|
||
indices of any type: in fact, <code><span class="identifier">splice</span></code>
|
||
can be regarded as a frontend to the same functionality provided
|
||
by <code><span class="identifier">merge</span></code> in key-based
|
||
indices. For reasons of backwards compatibility, the destructive
|
||
behavior of <code><span class="identifier">splice</span></code>
|
||
has been retained in the case that the source and destination containers
|
||
have unequal allocators.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
The fact has been documented that index iterator types do only depend
|
||
on <code><span class="identifier">node_type</span></code> and
|
||
the position of the index in its <code><span class="identifier">multi_index_container</span></code>,
|
||
(except for hashed indices, where uniqueness/non-uniqueness is also
|
||
a dependency). This has implications on the validity of iterators
|
||
to elements transferred by <code><span class="identifier">merge</span></code>
|
||
or <code><span class="identifier">splice</span></code>. This property
|
||
is a variant of what has been called <a href="https://wg21.link/n2980">SCARY
|
||
iterators</a> in the C++ standard mailing lists. SCARYness is
|
||
currently (August 2021) not mandated for standard containers.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Iterator SCARYness is now also preserved in <a href="https://www.boost.org/doc/libs/1_78_0_beta1/libs/multi_index/doc/tutorial/debug.html#safe_mode">safe
|
||

<strong>Introducing Boost.Filesystem v4.</strong>
|
||
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 <strong>v3</strong> and <strong>v4</strong> tags and are also summarised in a separate
|
||
section. Users can select Boost.Filesystem version by defining <code><span class="identifier">BOOST_FILESYSTEM_VERSION</span></code> 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.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
<strong>v4:</strong> <code><span class="identifier">path</span><span class="special">::</span><span class="identifier">filename</span></code>,
|
||
<code><span class="identifier">path</span><span class="special">::</span><span class="identifier">stem</span></code> and <code><span class="identifier">path</span><span class="special">::</span><span class="identifier">extension</span></code>
|
||
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
|
||
<code><span class="identifier">path</span><span class="special">(</span><span class="string">"C:"</span><span class="special">).</span><span class="identifier">filename</span><span class="special">()</span></code>
|
||
used to return "C:" and <code><span class="identifier">path</span><span class="special">(</span><span class="string">"C:\\"</span><span class="special">).</span><span class="identifier">filename</span><span class="special">()</span></code> used to return "\" and
|
||
both will return an empty path now. (<a href="https://github.com/boostorg/filesystem/issues/88">#88</a>, <a href="https://github.com/boostorg/filesystem/issues/194">#194</a>)

<strong>v4:</strong> <code><span class="identifier">path</span><span class="special">::</span><span class="identifier">stem</span></code>
|
||
and <code><span class="identifier">path</span><span class="special">::</span><span class="identifier">extension</span></code> 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. (<a href="https://github.com/boostorg/filesystem/issues/88">#88</a>)

<strong>New:</strong> 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. <code><span class="identifier">path</span><span class="special">(</span><span class="string">"\\\\.\\"</span><span class="special">).</span><span class="identifier">stem</span><span class="special">()</span>
|
||
<span class="special">==</span> <span class="string">"\\\\"</span></code>).
|
||
It is recommended to use the prefixes only with Boost.Filesystem
|
||
v4.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Reworked <code><span class="identifier">path</span><span class="special">::</span><span class="identifier">lexically_normal</span></code> implementation
|
||
to eliminate some cases of duplicate dot (".") elements
|
||
in the normalized paths.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
<strong>New:</strong> Added runtime detection of
|
||
the <code><span class="identifier">statx</span></code> and <code><span class="identifier">getrandom</span></code> system calls on Linux.
|
||
This can be useful if the syscall is present at compile time but
|
||
fails with <code><span class="identifier">ENOSYS</span></code>
|
||
at run time (for example, in Docker containers that restrict the
|
||
syscall, even if available on the host). (<a href="https://github.com/boostorg/filesystem/issues/172">#172</a>)
|
||
</div>
|
||
</li>
|
||
<li>
|

<div>
|
||
<strong>New:</strong> 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.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
<strong>New:</strong> Added <code><span class="identifier">copy_options</span><span class="special">::</span><span class="identifier">synchronize_data</span></code>
|
||
and <code><span class="identifier">copy_options</span><span class="special">::</span><span class="identifier">synchronize</span></code>
|
||
options for the <code><span class="identifier">copy_file</span></code>
|
||
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 <code><span class="identifier">copy_file</span></code>
|
||
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. (<a href="https://github.com/boostorg/filesystem/issues/186">#186</a>)
|

<li>
|

<div>
|

Added handling of <code><span class="identifier">EINTR</span></code>
|
||
error code on POSIX systems for some system calls issued internally.
|
||
In particular, <code><span class="identifier">EINTR</span></code>
|
||
could have been ignored on <code><span class="identifier">close</span></code>,
|
||
which on HP-UX would result in a leaked file descriptor.

</li>
|

<div>
|

In the <code><span class="identifier">copy_file</span></code>
|
||
implementations based on Linux <code><span class="identifier">sendfile</span></code>
|
||
and <code><span class="identifier">copy_file_range</span></code>
|
||
system calls, added handling of error codes indicating that a particular
|
||
filesystem does not support the system call and fall back to the
|
||
generic <code><span class="identifier">read</span></code>/<code><span class="identifier">write</span></code> loop. This should fix <code><span class="identifier">copy_file</span></code> failing on <a href="https://www.ecryptfs.org/">eCryptFS</a>
|
||
and possibly other filesystems. (<a href="https://github.com/boostorg/filesystem/issues/184">#184</a>)

<div>
|
||
The <code><span class="identifier">copy_file_range</span></code>
|
||
system call is now used since Linux kernel 4.5, whereas previously
|
||
it was only enabled since 5.3. The <code><span class="identifier">copy_file</span></code>
|
||
implementation will fall back to <code><span class="identifier">sendfile</span></code>
|
||
or <code><span class="identifier">read</span></code>/<code><span class="identifier">write</span></code> loop if <code><span class="identifier">copy_file_range</span></code>
|
||
fails to copy a given file across filesystems.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
The <code><span class="identifier">copy_file</span></code> implementations
|
||
based on Linux <code><span class="identifier">sendfile</span></code>
|
||
and <code><span class="identifier">copy_file_range</span></code>
|
||
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 <code><span class="identifier">read</span></code>/<code><span class="identifier">write</span></code> loop will be used instead.
|
||
Currently, the blacklisted filesystems are: procfs, sysfs, tracefs
|
||
and debugfs.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
In the <code><span class="identifier">copy_file</span></code>
|
||
implementation based on <code><span class="identifier">read</span></code>/<code><span class="identifier">write</span></code> 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.

</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
On Windows CE, calling <code><span class="identifier">current_path</span></code>
|
||
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.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
In <code><span class="identifier">canonical</span></code>, 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.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
In <code><span class="identifier">canonical</span></code>, added
|
||
a limit for the maximum number of symlinks that can be resolved during
|
||
the call. The limit is currently at least 40 symlinks.
|
||
</div>
|
||
</li>
|

<li>
|
||
<div>
|
||
On Windows, <code><span class="identifier">canonical</span></code>
|
||
and <code><span class="identifier">weakly_canonical</span></code>
|
||
will now use <code><span class="identifier">path</span><span class="special">::</span><span class="identifier">preferred_separator</span></code>
|
||
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 ("\\?\"). (<a href="https://github.com/boostorg/filesystem/issues/87">#87</a>, <a href="https://github.com/boostorg/filesystem/issues/187">#187</a>)

<strong>New:</strong> Added <code><span class="identifier">weakly_canonical</span></code>

<li>
|

<div>
|

On Windows, <code><span class="identifier">weakly_canonical</span></code>
|
||
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, <code><span class="identifier">weakly_canonical</span><span class="special">(</span><span class="string">"C:\\a\\.."</span><span class="special">)</span></code> would previously fail if "C:\a"
|
||
directory did not exist. (<a href="https://github.com/boostorg/filesystem/issues/201">#201</a>)

</li>
|

<li>
|

<div>
|
||
In <code><span class="identifier">read_symlink</span></code> on
|
||
Windows, corrected reparse point handling. The operation would return
|
||
an empty path for some mount points (for example, created by <a href="https://www.box.com/">Box</a> 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. (<a href="https://github.com/boostorg/filesystem/issues/187">#187</a>)

|

will use wide character paths on libc++ versions 7.0 and higher,

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 <code><span class="identifier">path</span><span class="special">::</span><span class="identifier">imbue</span></code>. The supported compilers
|
||
include MSVC, GCC and Clang, as well as other compilers that support
|
||
customizing program initialization order through <code><span class="preprocessor">#pragma</span>
|
||
<span class="identifier">section</span></code> (for MSVC-compatible

The conversion operator from <code><span class="identifier">error_category</span></code>
|
||
to <code><span class="identifier">std</span><span class="special">::</span><span class="identifier">error_category</span></code> has been improved
|
||
and no longer requires <code><span class="special">&lt;</span><span class="identifier">map</span><span class="special">&gt;</span></code>
|
||
or <code><span class="special">&lt;</span><span class="identifier">mutex</span><span class="special">&gt;</span></code>.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
The comparison operators of <code><span class="identifier">error_category</span></code>
|
||
are now inline friends instead of member functions (a side effect
|
||
of the previous change.)

</div>
|

</li>
|

<li>
|
||
<div>
|

<code><span class="identifier">error_condition</span></code> now
|
||
defers calling <code><span class="identifier">generic_category</span><span class="special">()</span></code> to avoid instantiating the object
|
||
until it's actually needed.
|
||
</div>
|
||
</li>
|

<li>
|

<div>
|

<code><span class="identifier">error_condition</span><span class="special">::</span><span class="identifier">failed</span></code> and <code><span class="identifier">error_condition</span><span class="special">::</span><span class="identifier">message</span></code>
|
||
have been undeprecated, and <code><span class="keyword">operator</span>
|
||
<span class="keyword">bool</span><span class="special">()</span></code>
|
||
now once again returns <code><span class="identifier">failed</span><span class="special">()</span></code>.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|

The system category now doesn't call <code><span class="identifier">generic_category</span><span class="special">()</span></code>, to avoid instantiating the object.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
The return value of <code><span class="identifier">default_error_condition</span></code>
|
||
changes in some cases into an <code><span class="identifier">error_condition</span></code>
|
||
from the generic category, instead of from the system category. This
|
||
happens on POSIX when the input <code><span class="identifier">error_code</span></code>
|
||
is from the system category and does not correspond to any <code><span class="identifier">errc_t</span></code> value.
|

The interoperability of <code><span class="identifier">error_code</span></code>
|
||
and <code><span class="identifier">std</span><span class="special">::</span><span class="identifier">error_code</span></code> has been improved substantially.
|
||
It is now possible to construct <code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">system</span><span class="special">::</span><span class="identifier">error_code</span></code>
|
||
from <code><span class="identifier">std</span><span class="special">::</span><span class="identifier">error_code</span></code>, and it's possible to
|
||
pass <code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">system</span><span class="special">::</span><span class="identifier">error_code</span></code> to functions taking
|
||
<code><span class="identifier">std</span><span class="special">::</span><span class="identifier">error_code</span><span class="special">&amp;</span></code>.
|
||
</div>

</li>
|

<li>

Replaced default standard exception classes with Boost.Container
|
||
own classes, reducing considerably the included files overhead. Example:
|
||
in MSVC 19 <code><span class="identifier">boost</span><span class="special">/</span><span class="identifier">container</span><span class="special">/</span><span class="identifier">vector</span><span class="special">.</span><span class="identifier">hpp</span></code>
|
||
preprocessed file size reduces from 1,5MB to 930KB. If you still
|
||
want to use standard exception classes, you can define <code><span class="identifier">BOOST_CONTAINER_USE_STD_EXCEPTIONS</span></code>
|
||
before using any Boost.Container class.

Bug fixes:

<div>
|
||
Corrected a formal race condition in the thread-safe log record
|
||
queue implementation used in the <code><span class="identifier">unbounded_fifo_queue</span></code>
|
||
policy of the <code><span class="identifier">asynchronous_sink</span></code>
|
||
frontend. The race could be detected by TSAN, but it was not
|
||
a real problem on most current CPU architectures and compilers.

<li>
|
||
<div>
|
||
When copying a logger with a channel attribute (e.g. <code><span class="identifier">channel_logger</span></code>), 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.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Replaced the use of <code><span class="identifier">std</span><span class="special">::</span><span class="identifier">allocator</span><span class="special">&lt;</span><span class="keyword">void</span><span class="special">&gt;</span></code> in template parameters
|
||
with a new tag type <code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">log</span><span class="special">::</span><span class="identifier">use_std_allocator</span></code>
|
||
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 <code><span class="identifier">std</span><span class="special">::</span><span class="identifier">allocator</span></code> internally to allocate
|
||
dynamic memory, so the change has no functional effect. (<a href="https://github.com/boostorg/log/issues/141">#141</a>)

Boost.Log no longer defines <code><span class="identifier">__MSVCRT_VERSION__</span></code>

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.

<div>
|
||
Enhancements:
|
||
<ul>
|
||
<li>
|
||
<div>
|
||
VS2019.8 changed how to enable Coroutines, which caused Outcome
|
||
to not compile on that compiler.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
If on C++ 20, we now use C++ 20 <code><span class="special">[[</span><span class="identifier">likely</span><span class="special">]]</span></code>
|
||
instead of compiler-specific markup to indicate when TRY has
|
||
likely success or failure.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
BREAKING CHANGE: Previously the value of <code><span class="identifier">spare_storage</span><span class="special">(</span><span class="keyword">const</span>
|
||
<span class="identifier">basic_result</span><span class="special">|</span><span class="identifier">basic_outcome</span> <span class="special">*)</span>
|
||
<span class="keyword">noexcept</span></code> was not propagated
|
||
over <code><span class="identifier">BOOST_OUTCOME_TRY</span></code>,
|
||
which causes things like stack backtraces captured at the point
|
||
of construction of an errored result to get dropped at every
|
||
<code><span class="identifier">TRY</span></code> point.
|
||
This has been fixed by adding an optional <code><span class="identifier">spare_storage</span></code>
|
||
to <code><span class="identifier">success_type</span><span class="special">&lt;</span><span class="identifier">T</span><span class="special">&gt;</span></code> and <code><span class="identifier">failure_type</span><span class="special">&lt;</span><span class="identifier">T</span><span class="special">&gt;</span></code>, as well as to <code><span class="keyword">auto</span> <span class="identifier">success</span><span class="special">(</span><span class="identifier">T</span>
|
||
<span class="special">&amp;&amp;,</span> <span class="special">...)</span></code>
|
||
and <code><span class="keyword">auto</span> <span class="identifier">failure</span><span class="special">(</span><span class="identifier">T</span>
|
||
<span class="special">&amp;&amp;,</span> <span class="special">...)</span></code>.

Bug fixes:
|

<ul>
|
||
<li>
|
||
<div>
|
||
Boost.Outcome should now compile with <code><span class="identifier">BOOST_NO_EXCEPTIONS</span></code>
|
||
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 <code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">exception_ptr</span></code> as it can't
|
||
be included if C++ exceptions are globally disabled.

BREAKING CHANGE <a href="https://github.com/ned14/outcome/issues/244">#244</a>
|
||
It came as a shock to learn that <code><span class="identifier">BOOST_OUTCOME_TRY</span></code>
|
||
had been broken since the inception of this library for certain
|
||
corner case code, which required a breaking change in how TRY
|
||
works. See <a href="https://boostorg.github.io/outcome/changelog.html">the
|
||
changelog in the documentation for more detail</a>.

<h3><span class="link">Known Issues</span></h3>
|
||
<p>
|
||
Boost.Operators is currently <strong>incompatible with C++20</strong>
|
||
compilers, which in some cases may manifest as an infinite recursion or infinite
|
||
loop in runtime when a comparison operator is called. The problem is caused
|
||
by the new operator rewriting behavior introduced in C++20. As a workaround,
|
||
users are advised to target C++17 or older C++ standard. More details can be
|
||
found in <a href="https://github.com/boostorg/utility/issues/65">#65</a>.

Announcements:

|
||
After a year and three major Boost releases announcing this
|
||
upcoming change, this is the FINAL RELEASE of the v2.1 branch.
|
||
From Boost 1.76 onwards, the v2.2 branch becomes the default.
|
||
This branch has a number of major breaking changes to Outcome
|
||
v2.1, see the documentation for details.

Enhancements:
|
||
<ul>
|
||
<li>
|
||
<div>
|
||
The ADL discovered event hooks have been replaced with policy-specified
|
||
event hooks instead. This is due to brittleness (where hooks
|
||
would quietly self-disable if somebody changed something),
|
||
compiler bugs (a difference in compiler settings causes the
|
||
wrong hooks, or some but not all hooks, to get discovered),
|
||
and end user difficulty in using them at all. The policy-specified
|
||
event hooks can be told to default to ADL discovered hooks
|
||
for backwards compatibility: set <code><span class="identifier">OUTCOME_ENABLE_LEGACY_SUPPORT_FOR</span></code>
|
||
to less than <code><span class="number">220</span></code>
|
||
to enable emulation.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Improve configuring <code><span class="identifier">OUTCOME_GCC6_CONCEPT_BOOL</span></code>.
|
||
Older GCCs had boolean based concepts syntax, whereas newer
|
||
GCCs are standards conforming. However the precise logic of
|
||
when to use legacy and conforming syntax was not well understood,
|
||
which caused Outcome to fail to compile depending on what options
|
||
you pass to GCC. The new logic always uses the legacy syntax
|
||
if on GCC 8 or older, otherwise we use conforming syntax if
|
||
and only if GCC is in C++ 20 mode or later. This hopefully
|
||
will resolve the corner case build failures on GCC.

|
||
Boost.Outcome should now compile with <code><span class="identifier">BOOST_NO_EXCEPTIONS</span></code>
|
||
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 <code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">exception_ptr</span></code> as it can't
|
||
be included if C++ exceptions are globally disabled.

|

In the Coroutine support the <code><span class="identifier">final_suspend</span><span class="special">()</span></code> was not <code><span class="keyword">noexcept</span></code>,
|
||
despite being required to be so in the C++ 20 standard. This
|
||
has been fixed, but only if your compiler implements <code><span class="identifier">noop_coroutine</span></code>. Additionally,
|
||
if <code><span class="identifier">noop_coroutine</span></code>
|
||
is available, we use the much more efficient coroutine handle

When variadic data is empty in C++20 mode with __VA_OPT__ support
|
||
the variadic size has been corrected to be 0. This also means that
|
||
in this C++20 mode it is now valid to convert to and from empty arrays
|
||
and lists and variadic data. The end-user can read the "C++20
|
||
Support For Variadic Macros" part of the "variadic macros"
|
||
topic for more information about empty variadic data in the library.

|

<div>
|
||
The macro BOOST_PP_IS_STANDARD() has been added for identifying if
|
||
the currently used preprocessor is a C++ standard conforming preprocessor.
|
||
A number of preprocessors which generally work correctly with the
|
||
library but need various internal workarounds, including the currently
|
||
default VC++ preprocessor, are not considered C++ standard conforming
|
||
preprocessors. However most preprocessors, including among others
|
||
gcc, clang, and the new but currently non-default VC++ preprocessor
|
||
in VS2019, are C++ standard conforming preprocessors.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
For C++ standard conforming preprocessors a number of the limits
|
||
defined in the config/limits.hpp can now be changed to higher amounts
|
||
for a TU. The end-user should read the "limitations" topic
|
||
to understand how and which limits can be changed.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
For C++ standard conforming preprocessors, in order to allow the
|
||
maximum number of FOR and WHILE iterations, the beginning 'r' and
|
||
'd' iteration numbers in the user-defined macros start at 1 and not
|
||
2, as it did in previous releases. This could be a breaking change
|
||
if these iteration numbers are used in the user-defined macros (
|
||
they probably would not be ), but the change was necessary to fix
|
||
some arcane bugs when dealing with numerical/logical operations with
|
||
maximum numbers as well to allow the user-defined macros to be called
|
||
the correct possible maximum number of times. For non-C++ conforming
|
||
preprocessors, this change was not made because those non-conforming
|
||
C++ preprocessors generally have limitations which disallow the maximum
|
||
number of looping constructs to be run, and it was felt not to introduce
|
||
a possible breaking change to those more fragile preprocessors would
|
||
be better. It was also felt that besides fixing some arcane preprocessor
|
||
bugs and providing the possible maximum number of user-defined macro
|
||
invocations, this change could be made because it has never been
|
||
documented what the starting 'r' and 'd' iteration numbers actually
|
||
are but only that these numbers are incremented for each iteration.

The library has been upgraded to assume variadic macro support for
|
||
any compiler working with the library. Ostensibly this means that
|
||
the library is now a C++11 on up library, yet most of the major compilers,
|
||
including gcc, clang, and VC++, also support variadic macros in C++98/C++03
|
||
mode as long as strict compliance to C++98/C++03 is not turned on
|
||
when using one of those compilers.

Added support for the proposed standard executors to Asio's I/O facilities.
|

The <code><span class="identifier">any_io_executor</span></code>
|

type alias has been introduced as the default runtime-polymorphic
|

executor for all I/O objects. This defaults to the <code><span class="identifier">execution</span><span class="special">::</span><span class="identifier">any_executor</span><span class="special">&lt;&gt;</span></code>
|
||
template. If required for backward compatibility, <code><span class="identifier">BOOST_ASIO_USE_TS_EXECUTOR_AS_DEFAULT</span></code>

|

<ul>
|

<li>
|

<div>
|
||
Added missing <code><span class="keyword">const</span></code>
|

qualifiers to some operations in <code><span class="identifier">atomic_ref</span></code>.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Added support for <code><span class="identifier">yield</span></code>
|
||
instruction on ARMv8-A. The instruction is used internally in spin
|
||
loops to reduce CPU power consumption.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Added support for C++20 <a href="https://www.boost.org/doc/html/atomic/interface.html#atomic.interface.interface_wait_notify_ops">waiting
|
||
and notifying operations</a>. The implementation includes generic
|
||
backend that involves the internal lock pool, as well as specialized
|
||
backends for Windows, Linux, FreeBSD, DragonFly BSD and NetBSD. Atomic
|
||
types provide a new method <code><span class="identifier">has_native_wait_notify</span></code>,
|
||
a static boolean constant <code><span class="identifier">always_has_native_wait_notify</span></code>
|
||
and a set of capability macros that allow to detect if the implementation
|
||
supports native waiting and notifying operations for a given type.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Changed internal representation of <code><span class="identifier">atomic_flag</span></code>
|
||
to use 32-bit storage. This allows for more efficient waiting and
|
||
notifying operations on <code><span class="identifier">atomic_flag</span></code>
|
||
on some platforms.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Added support for build-time configuration of the internal lock pool
|
||
size. The user can define the <code><span class="identifier">BOOST_ATOMIC_LOCK_POOL_SIZE_LOG2</span></code>
|
||
macro to specify binary logarithm of the size of the lock pool. The
|
||
default value is 8, meaning that the size of the lock pool is 256,
|
||
up from 64 used in the previous release.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Added support for a new set of atomic types dedicated for <a href="https://www.boost.org/doc/html/atomic/interface.html#atomic.interface.interface_ipc">inter-process
|
||
communication</a>: <code><span class="identifier">ipc_atomic_flag</span></code>,
|
||
<code><span class="identifier">ipc_atomic</span></code> and <code><span class="identifier">ipc_atomic_ref</span></code>. Users are recommended
|
||
to port their code using non-IPC types for inter-process communication
|
||
to the new types. The new types provide the same set of operations
|
||
as their non-IPC counterparts, with the following differences:
|
||
<ul>
|
||
<li>
|
||
<div>
|
||
Most operations have an added precondition that <code><span class="identifier">is_lock_free</span></code> returns <code><span class="keyword">true</span></code> for the given atomic object.
|
||
The library will issue a compile time error if this precondition
|
||
is known to be not satisfied at compile time.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
All provided operations are address-free, meaning that the
|
||
atomic object (in case of <code><span class="identifier">ipc_atomic_ref</span></code>
|
||
- the referenced object) may be located in process-shared memory
|
||
or mapped into the same process at multiple different addresses.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
The new <code><span class="identifier">has_native_wait_notify</span></code>
|
||
operation and <code><span class="identifier">always_has_native_wait_notify</span></code>
|
||
constant indicate support for native inter-process waiting
|
||
and notifying operations. When that support is not present,
|
||
the operations are implemented with a busy loop, which is less
|
||
efficient, but still is address-free. A separate set of capability
|
||
macros is also provided to indicate this support.
|
||
</div>
|
||
</li>
|
||
</ul>
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Added new <code><span class="identifier">atomic_unsigned_lock_free</span></code>
|
||
and <code><span class="identifier">atomic_signed_lock_free</span></code>
|
||
types introduced in C++20. The types indicate the atomic object type
|
||
for an unsigned or signed integer, respectively, that is lock-free
|
||
and preferably has native support for waiting and notifying operations.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Added new gcc assembler backends for ARMv8-A (for both AArch32 and
|
||
AArch64). The new backends are used to implement operations not supported
|
||
by compiler intrinsics (including 128-bit operations on AArch64)
|
||
and can also be used when compiler intrinsics are not available.
|
||
Both little and big endian targets are supported. AArch64 backend
|
||
supports extensions defined in ARMv8.1 and ARMv8.3.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Added support for big endian targets in the legacy ARM backend based
|
||
on gcc assembler blocks (this backend is used on ARMv7 and older
|
||
targets). Previously, the backend assumed little endian memory layout,
|
||
which is significant for 64-bit operations.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Improved performance of seq_cst stores and thread fences on x86 by
|
||
using <code><span class="identifier">lock</span></code>-prefixed
|
||
instructions instead of <code><span class="identifier">mfence</span></code>.
|
||
This means that the operations no longer affect non-temporal stores,
|
||
which was also not guaranteed before. Use specialized instructions
|
||
and intrinsics to order non-temporal memory accesses.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Fixed capability macros for 80-bit <code><span class="keyword">long</span>
|
||
<span class="keyword">double</span></code> on x86 targets not
|
||
indicating lock-free operations even if 128-bit atomic operations
|
||
were available.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Fixed compilation of gcc asm blocks on Alpha targets.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
In the gcc <code><span class="identifier">__sync</span><span class="special">*</span></code> intrinsics backend, fixed that store
|
||
and load operations of large objects (larger than a pointer size)
|
||
could be non-atomic. The implementation currently assumes that small
|
||
objects can be stored with a single instruction atomically on all
|
||
modern architectures.

<li>
|

<li>
|

<div>
|

Beast also supports <code><span class="identifier">BOOST_ASIO_NO_TS_EXECUTORS</span></code>.
|

TS</a>
|

</div>

Asio will use the <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p0443r11.html">Standard
|
||
Executors</a> model by default. You can prevent this behaviour
|
||
by defining <code><span class="identifier">BOOST_ASIO_USE_TS_EXECUTOR_AS_DEFAULT</span></code>
|
||
in which the Networking TS model will be used by default. Setting
|
||
this flag does not prevent a program from using executors from the
|
||
Standard Executors model explicitly.

Implemented the allocator access utilities which provide a replacement
|
||
for <code><span class="identifier">allocator_traits</span></code>
|
||
with individual traits and functions for each facility. They support
|
||
the C++11 allocator model when possible and provide a fallback for
|
||
C++98 compatibility. These are now used in Circular_Buffer, Wave,
|
||
Lockfree, Heap, Smart_Ptr, Dynamic_Bitset, Format, Bimap and more.

<code><span class="identifier">copy_file</span></code> implementation

as required by C++20 ([fs.op.copy.file]/4.1). In particular, the

file or the source and target paths identify the same file.

</li>
|

<li>
|

<div>

<code><span class="identifier">copy_file</span></code> on POSIX

<strong>Deprecated:</strong> The <code><span class="identifier">copy_option</span></code>
|
||
enumeration that is used with the <code><span class="identifier">copy_file</span></code>
|
||
operation is deprecated. As a replacement, the new enum <code><span class="identifier">copy_options</span></code> (note the trailing
|
||
's') has been added. The new enum contains values similar to the
|
||
<code><span class="identifier">copy_options</span></code> enum
|
||
from C++20. The old enum values are mapped onto the new enum. The
|
||
old enum will be removed in a future release.

<div>

<strong>New:</strong> Added <code><span class="identifier">copy_options</span><span class="special">::</span><span class="identifier">update_existing</span></code>

if its last write time is older than that of the replacement file.
|
||
</div>

||
</li>
|
||
<li>
|

<div>
|

<strong>New:</strong> <code><span class="identifier">copy_file</span></code>

indicates whether the file was copied.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
<strong>New, breaking change:</strong> <code><span class="identifier">copy</span></code> operation has been extended
|
||
and reworked to implement behavior specified in C++20 [fs.op.copy].
|
||
This includes support for <code><span class="identifier">copy_options</span><span class="special">::</span><span class="identifier">recursive</span></code>,
|
||
<code><span class="identifier">copy_options</span><span class="special">::</span><span class="identifier">copy_symlinks</span></code>, <code><span class="identifier">copy_options</span><span class="special">::</span><span class="identifier">skip_symlinks</span></code>,
|
||
<code><span class="identifier">copy_options</span><span class="special">::</span><span class="identifier">directories_only</span></code>, <code><span class="identifier">copy_options</span><span class="special">::</span><span class="identifier">create_symlinks</span></code> and <code><span class="identifier">copy_options</span><span class="special">::</span><span class="identifier">create_hard_links</span></code> options. The
|
||
operation performs additional checks based on the specified options.
|
||
Applying <code><span class="identifier">copy</span></code> to
|
||
a directory with default <code><span class="identifier">copy_options</span></code>
|
||
will now also copy files residing in that directory (but not nested
|
||
directories or files in those directories).
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
<strong>New:</strong> Added <code><span class="identifier">create_directory</span></code>
|
||
overload taking two paths. The second path is a path to an existing
|
||
directory, which is used as a source of permission attributes to
|
||
use in the directory to create.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>

<strong>Deprecated:</strong> <code><span class="identifier">copy_directory</span></code>

operation has been deprecated in favor of the new <code><span class="identifier">create_directory</span></code>
|
||
overload. Note that the two operations have reversed order of the
|
||
path arguments.

</li>
|
||
<li>
|

<div>
|
||
<code><span class="identifier">equivalent</span></code> on POSIX
|

systems now returns the actual error code from the OS if one of the
|
||
paths does not resolve to a file. Previously the function would return
|
||
an error code of 1. (<a href="https://github.com/boostorg/filesystem/issues/141">#141</a>)
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
<code><span class="identifier">equivalent</span></code> no longer
|
||
considers file size and last modification time in order to test whether
|
||
the two paths refer to the same file. These checks could result in
|
||
a false negative if the file was modified during the <code><span class="identifier">equivalent</span></code> call.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
<strong>New:</strong> Added <code><span class="identifier">absolute</span></code>

overloads taking <code><span class="identifier">error_code</span></code>
|
||
argument.
|
||
</div>
|

<li>
|

<div>
|

Operations that have <code><span class="identifier">current_path</span><span class="special">()</span></code> as the default value of their arguments
|
||
and also have an <code><span class="identifier">error_code</span></code>
|
||
argument will use the <code><span class="identifier">current_path</span><span class="special">(</span><span class="identifier">error_code</span><span class="special">&amp;</span> <span class="identifier">ec</span><span class="special">)</span></code> overload to obtain the current path,
|
||
so that its failure is reported via the <code><span class="identifier">error_code</span></code>
|
||
argument instead of an exception.
|
||
</div>
|
||
</li>
|
||
<li>
|

<div>
|
||
<code><span class="identifier">space</span></code> now initializes

the <code><span class="identifier">space_info</span></code> structure

members to -1 values on error, as required by C++20 ([fs.op.space]/1).
|
||

|
||
</li>
|
||
<li>
|
||
<div>
|
||
<code><span class="identifier">space</span></code> on Windows

description in C++20. (<a href="https://github.com/boostorg/filesystem/issues/73">#73</a>)

<strong>Deprecated:</strong> Auto-linking against

system libraries on Windows with MSVC-compatible compilers is deprecated

||
against static library of Boost.Filesystem. Users are advised to
|
||
update their project build systems to either use a shared library
|
||
of Boost.Filesystem, or explicitly specify the dependencies of Boost.Filesystem

in the linker command line. Users of shared library of Boost.Filesystem

are not affected.

The syslog sink backend now verifies the IP version of the
|
||
local and target addresses set by user. The addresses must
|
||
have the same IP version as was specified in the <code><span class="identifier">ip_version</span></code> named parameter
|
||
on the sink backend construction (by default, IPv4 is assumed).
|
||
When an address is obtained as a result of host name resolution,

only addresses with matching IP version are considered. (<a href="https://github.com/boostorg/log/issues/119">#119</a>)

The v2.1 branch is expected to be retired end of 2020, with
|
||
the v2.2 branch becoming the default. You can use the future
|
||
v2.2 branch now using <a href="https://github.com/ned14/outcome/tree/better_optimisation"><code><span class="identifier">better_optimisation</span></code></a>.
|
||
This branch has a number of major breaking changes to Outcome
|
||
v2.1, see the front page for details.

|

<div>
|
||
BREAKING CHANGE <code><span class="keyword">void</span></code>
|
||
results and outcomes no longer default construct types during
|
||
explicit construction. Previously if you explicitly constructed
|
||
a <code><span class="identifier">result</span><span class="special">&lt;</span><span class="identifier">T</span><span class="special">&gt;</span></code>
|
||
from a non-errored <code><span class="identifier">result</span><span class="special">&lt;</span><span class="keyword">void</span><span class="special">&gt;</span></code>, it default constructed
|
||
<code><span class="identifier">T</span></code>. This was
|
||
found to cause unhelpful surprise, so it has been disabled.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
New macro <code><span class="identifier">OUTCOME_ENABLE_LEGACY_SUPPORT_FOR</span></code>.
|
||
The macro <code><span class="identifier">OUTCOME_ENABLE_LEGACY_SUPPORT_FOR</span></code>
|
||
can be used to enable aliasing of older naming and features
|
||
to newer naming and features when using a newer version of
|
||
Outcome.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Concepts now have snake case style naming instead of camel
|
||
case style. When Outcome was first implemented, it was thought
|
||
that C++ 20 concepts were going to have camel case style. This
|
||
was changed before the C++ 20 release, and Outcome's concepts
|
||
have been renamed similarly. This won't break any code in Outcome
|
||
v2.1, as compatibility aliases are provided. However code compiled
|
||
against Outcome v2.2 will need to be upgraded, unless <code><span class="identifier">OUTCOME_ENABLE_LEGACY_SUPPORT_FOR</span></code>
|
||
is set to <code><span class="number">210</span></code> or
|
||
lower.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Concepts now live in <code><span class="identifier">OUTCOME_V2_NAMESPACE</span><span class="special">::</span><span class="identifier">concepts</span></code>
|
||
namespace. Previously concepts lived in the <code><span class="identifier">convert</span></code>
|
||
namespace, now they live in their own namespace.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
New concepts <code><span class="identifier">basic_result</span><span class="special">&lt;</span><span class="identifier">T</span><span class="special">&gt;</span></code> and <code><span class="identifier">basic_outcome</span><span class="special">&lt;</span><span class="identifier">T</span><span class="special">&gt;</span></code> added. End users were finding
|
||
an unhelpful gap in between <code><span class="identifier">is_basic_result</span><span class="special">&lt;</span><span class="identifier">T</span><span class="special">&gt;</span></code> and <code><span class="identifier">value_or_error</span><span class="special">&lt;</span><span class="identifier">T</span><span class="special">&gt;</span></code> where they wanted a concept
|
||
that matched types which were <code><span class="identifier">basic_result</span></code>,
|
||
but not exactly one of those. Concepts filling that gap were
|
||
added.
|
||
</div>
|
||
</li>
|
||
<li>
|
||
<div>
|
||
Operation <code><span class="identifier">TRY</span></code>
|
||
works differently from Outcome v2.2 onwards. This is a severely
|
||
code breaking change which change the syntax of how one uses
|
||
<code><span class="identifier">OUTCOME_TRY</span><span class="special">()</span></code>. A regular expression suitable
|
||
for upgrading code can be found in the list of changes between
|
||
Outcome v2.1 and v2.2.

The clang Apple ships in Xcode 11.4 (currently the latest)
|
||
has not been patched with the fixes to LLVM clang that fix
|
||
<code><span class="keyword">noexcept</span><span class="special">(</span><span class="identifier">std</span><span class="special">::</span><span class="identifier">is_constructible</span><span class="special">&lt;</span><span class="identifier">T</span><span class="special">,</span>
|
||
<span class="keyword">void</span><span class="special">&gt;)</span></code>
|
||
failing to compile which I originally submitted years ago.
|
||
So give up waiting on Apple to fix their clang, add a workaround
|
||
to Outcome.

Spare storage could not be used from within no-value policy

at the time, the spare storage APIs had the wrong prototype
