<div>

Added <code><span class="identifier">directory_entry</span><span class="special">::</span><span class="identifier">refresh</span></code>
|
|
method that updates internal cached file statuses for the directory
|
|
entry identified by path.

<li>
|

<div>

<strong>v4:</strong> <code><span class="identifier">directory_entry</span></code>
|
|
constructors and modifiers that initialize or modify the path now
|
|
automatically call <code><span class="identifier">refresh</span></code>.
|
|
This may result in errors that were not indicated before and in
|
|
<strong>v3</strong>, if querying the filesystem for
|
|
file statuses fails (e.g. if the file does not exist). This new behavior
|
|
is similar to std::filesystem.

</div>
|

</li>
|
|
<li>
|
|
<div>
|
|
<strong>v4:</strong> <code><span class="identifier">directory_entry</span></code>
|
|
constructors and methods taking <code><span class="identifier">file_status</span></code>
|
|
parameters are removed. Users are recommended to remove these arguments
|
|
and rely on <code><span class="identifier">directory_entry</span></code>
|
|
calling <code><span class="identifier">refresh</span></code> internally.
|
|
</div>
|
|
</li>
|
|
<li>
|
|
<div>
|
|
Added <code><span class="identifier">directory_entry</span></code>
|
|
member methods for checking the file type of the file, similar to
|
|
std::filesystem.
|
|
</div>
|
|
</li>
|
|
<li>
|
|
<div>
|
|
Added more methods for testing file status: <code><span class="identifier">is_block_file</span></code>,
|
|
<code><span class="identifier">is_character_file</span></code>,
|
|
<code><span class="identifier">is_fifo</span></code>, <code><span class="identifier">is_socket</span></code> and <code><span class="identifier">is_reparse_file</span></code>.

</li>
|
|
<li>
|
|
<div>
|
|
<code><span class="identifier">recursive_directory_iterator</span></code>
|
|
is now more likely to reuse information about the file type that
|
|
is obtained during filesystem iteration. This may improve performance.

<div>

File streams defined in <code><span class="identifier">boost</span><span class="special">/</span><span class="identifier">filesystem</span><span class="special">/</span><span class="identifier">fstream</span><span class="special">.</span><span class="identifier">hpp</span></code>

|
|
</div>
|

</li>
|

<li>

<div>

Added a new header <code><span class="identifier">boost</span><span class="special">/</span><span class="identifier">filesystem</span><span class="special">/</span><span class="identifier">cstdio</span><span class="special">.</span><span class="identifier">hpp</span></code>
|
|
with a portable <code><span class="identifier">fopen</span></code>
|
|
overload that takes <code><span class="identifier">path</span></code>
|
|
as the first argument. This function is equivalent to <code><span class="identifier">std</span><span class="special">::</span><span class="identifier">fopen</span></code>, except that on Windows it
|
|
uses the native wide character encoding for paths.
|

</div>

|
</li>
|
|
<li>
|
|
<div>
|
|
Generic <code><span class="identifier">path</span></code> comparison
|
|
operators are now more restricted to avoid potential ambiguities
|
|
when user's code contains a <code><span class="keyword">using</span>
|
|
<span class="keyword">namespace</span> <span class="identifier">boost</span><span class="special">::</span><span class="identifier">filesystem</span><span class="special">;</span></code> directive. (<a href="https://github.com/boostorg/filesystem/issues/285">#285</a>)
|
|
</div>
|
|
</li>
|
|
<li>
|
|
<div>
|
|
Fixed potential overload resolution ambiguity in users' code, where
|
|
<code><span class="identifier">path</span></code> constructors
|
|
from iterators could interfere with function overloads taking a
|
|
<code><span class="identifier">std</span><span class="special">::</span><span class="identifier">initializer_list</span></code> argument. (<a href="https://github.com/boostorg/filesystem/issues/287">#287</a>)

On Windows, added more workarounds for errors returned by various
|
|
filesystems when creating a directory iterator. (<a href="https://github.com/boostorg/filesystem/issues/284">#284</a>,

Improved generated x86 code for AVX targets. Removed the use of
|
|
<code><span class="identifier">lddqu</span></code> instruction
|
|
on SSE3 targets, which penalize performance on Intel NetBurst CPUs
|
|
but is more optimal on Skylake and later CPUs. (<a href="https://github.com/boostorg/uuid/pull/138">PR#138</a>)

This release (1.82) and the next (1.83) will be the last releases offering
|
|
C++03 support for the above libraries and most of their dependencies.
|
|
</p>
|
|
<p>
|
|
The new baseline requirement for the above libraries, and for most of Boost,
|
|
will be C++11. Since old compiler versions often implement C++11 only partially,
|
|
due to missing support or bugs, what compilers are considered to meet the C++11
|
|
requirement may vary by library.
|
|
</p>
|
|
<p>
|
|
However, a general rule is that if a compiler does not recognize a C++11 keyword
|
|
or syntax at all (e.g. use of <code><span class="keyword">noexcept</span></code>,
|
|
use of <code><span class="keyword">constexpr</span></code>, or defining
|
|
a <code><span class="special">=</span><span class="keyword">delete</span></code>d
|
|
function results in an immediate compile error), or if a compiler does not
|
|
provide a required C++11 header at all (e.g. trying to include <code><span class="special">&lt;</span><span class="identifier">atomic</span><span class="special">&gt;</span></code> or <code><span class="special">&lt;</span><span class="identifier">chrono</span><span class="special">&gt;</span></code>
|
|
fails), or the compiler provides a C++11 feature or a header that is completely
|
|
unusable, this compiler is not considered a C++11 compiler.
|
|
</p>
|
|
<p>
|
|
This rules out, for instance, Microsoft Visual C++ before 14.0, or GCC before
|
|
4.8.

<div>
|
|
The specializations of <code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">hash</span></code>

<div>

All standard containers are now supported. This includes <code><span class="identifier">std</span><span class="special">::</span><span class="identifier">forward_list</span></code> and the unordered

associative containers.
|

User-defined containers (types that have <code><span class="identifier">begin</span><span class="special">()</span></code> and <code><span class="identifier">end</span><span class="special">()</span></code> member functions that return iterators)
|

The performance (and quality, as a result of the above change) of

string hashing has been improved. <code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">hash</span></code>

when the option <code><span class="special">-</span><span class="identifier">pedantic</span></code>
