@ -17,6 +17,56 @@ Test Suite Tasks
* Improve the quality and portability of the locale test data.
* Convert failure tests to use Clang Verify.
Filesystem Tasks
================
* P0492r2 - Implement National body comments for Filesystem
* INCOMPLETE - US 25: has_filename() is equivalent to just !empty()
* INCOMPLETE - US 31: Everything is defined in terms of one implicit host system
* INCOMPLETE - US 32: Meaning of 27.10.2.1 unclear
* INCOMPLETE - US 33: Definition of canonical path problematic
* INCOMPLETE - US 34: Are there attributes of a file that are not an aspect of the file system?
* INCOMPLETE - US 35: What synchronization is required to avoid a file system race?
* INCOMPLETE - US 36: Symbolic links themselves are attached to a directory via (hard) links
* INCOMPLETE - US 37: The term “redundant current directory (dot) elements” is not defined
* INCOMPLETE - US 38: Duplicates §17.3.16
* INCOMPLETE - US 39: Remove note: Dot and dot-dot are not directories
* INCOMPLETE - US 40: Not all directories have a parent.
* INCOMPLETE - US 41: The term “parent directory” for a (non-directory) file is unusual
* INCOMPLETE - US 42: Pathname resolution does not always resolve a symlink
* INCOMPLETE - US 43: Concerns about encoded character types
* INCOMPLETE - US 44: Definition of path in terms of a string requires leaky abstraction
* INCOMPLETE - US 45: Generic format portability compromised by unspecified root-name
* INCOMPLETE - US 46: filename can be empty so productions for relative-path are redundant
* INCOMPLETE - US 47: “.” and “..” already match the name production
* INCOMPLETE - US 48: Multiple separators are often meaningful in a root-name
* INCOMPLETE - US 49: What does “method of conversion method” mean?
* INCOMPLETE - US 50: 27.10.8.1 ¶ 1.4 largely redundant with ¶ 1.3
* INCOMPLETE - US 51: Failing to add / when appending empty string prevents useful apps
* INCOMPLETE - US 52: remove_filename() postcondition is not by itself a definition
* INCOMPLETE - US 53: remove_filename()'s name does not correspond to its behavior
* INCOMPLETE - US 54: remove_filename() is broken
* INCOMPLETE - US 55: replace_extension()'s use of path as parameter is inappropriate
* INCOMPLETE - US 56: Remove replace_extension()'s conditional addition of period
* INCOMPLETE - US 57: On Windows, absolute paths will sort in among relative paths
* INCOMPLETE - US 58: parent_path() behavior for root paths is useless
* INCOMPLETE - US 59: filename() returning path for single path components is bizarre
* INCOMPLETE - US 60: path("/foo/").filename()==path(".") is surprising
* INCOMPLETE - US 61: Leading dots in filename() should not begin an extension
* INCOMPLETE - US 62: It is important that stem()+extension()==filename()
* INCOMPLETE - US 63: lexically_normal() inconsistently treats trailing "/" but not "/.." as directory
* INCOMPLETE - US 73, CA 2: root-name is effectively implementation defined
* INCOMPLETE - US 74, CA 3: The term “pathname” is ambiguous in some contexts
* INCOMPLETE - US 75, CA 4: Extra flag in path constructors is needed
* INCOMPLETE - US 76, CA 5: root-name definition is over-specified.
* INCOMPLETE - US 77, CA 6: operator/ and other appends not useful if arg has root-name
* INCOMPLETE - US 78, CA 7: Member absolute() in 27.10.4.1 is overspecified for non-POSIX-like O/S
* INCOMPLETE - US 79, CA 8: Some operation functions are overspecified for implementation-defined file types
* INCOMPLETE - US 185: Fold error_code and non-error_code signatures into one signature
* INCOMPLETE - FI 14: directory_entry comparisons are members
* INCOMPLETE - Late 36: permissions() error_code overload should be noexcept
* INCOMPLETE - Late 37: permissions() actions should be separate parameter
* INCOMPLETE - Late 42: resize_file() Postcondition missing argument
Misc Tasks
==========
* Find all sequences of >2 underscores and eradicate them.

Experimental Support for Windows
--------------------------------
The Windows support requires building with clang-cl as cl does not support one
required extension: `#include_next`. Furthermore, VS 2015 or newer (19.00) is
required. In the case of clang-cl, we need to specify the "MS Compatibility
Version" as it defaults to 2014 (18.00).
CMake + Visual Studio
~~~~~~~~~~~~~~~~~~~~~
Building with Visual Studio currently does not permit running tests. However,
it is the simplest way to build.
.. code-block:: batch
> cmake -G "Visual Studio 14 2015" ^
-T "LLVM-vs2014" ^
-DLIBCXX_ENABLE_SHARED=YES ^
-DLIBCXX_ENABLE_STATIC=NO ^
-DLIBCXX_ENABLE_EXPERIMENTAL_LIBRARY=NO ^
\path\to\libcxx
> cmake --build .
CMake + ninja
~~~~~~~~~~~~~
Building with ninja is required for development to enable tests.
Unfortunately, doing so requires additional configuration as we cannot
just specify a toolset.
.. code-block:: batch
> cmake -G Ninja ^
-DCMAKE_MAKE_PROGRAM=/path/to/ninja ^
-DCMAKE_SYSTEM_NAME=Windows ^
-DCMAKE_C_COMPILER=clang-cl ^
-DCMAKE_C_FLAGS="-fms-compatibility-version=19.00 --target=i686--windows" ^
-DCMAKE_CXX_COMPILER=clang-c ^

-DLIBCXX_ENABLE_STATIC=NO ^
-DLIBCXX_ENABLE_EXPERIMENTAL_LIBRARY=NO ^
\path\to\libcxx
> /path/to/ninja cxx
> /path/to/ninja check-cxx
Note that the paths specified with backward slashes must use the `\\` as the
directory separator as clang-cl may otherwise parse the path as an argument.

External Threading Library
==========================
Normally ``<__threading_support>`` provides inline definitions to each internal
threading API function it declares. However libc++ also supports using an
external library to provide the definitions.
libc++ can be compiled with its internal threading API delegating to an external
library. Such a configuration is useful for library vendors who wish to
distribute a thread-agnostic libc++ library, where the users of the library are
expected to provide the implementation of the libc++ internal threading API.
When ``_LIBCPP_HAS_THREAD_LIBRARY_EXTERNAL`` libc++ does not provide inline
definitions for the internal API, instead assuming the definitions will be
provided by an external library.
On a production setting, this would be achieved through a custom
``<__external_threading>`` header, which declares the libc++ internal threading
API but leaves out the implementation.
The ``-DLIBCXX_BUILD_EXTERNAL_THREAD_LIBRARY`` option allows building libc++ in
such a configuration while allowing it to be tested on a platform that supports
any of the threading systems (e.g. pthread) supported in ``__threading_support``
header. Therefore, the main purpose of this option is to allow testing of this
particular configuration of the library without being tied to a vendor-specific
threading system. This option is only meant to be used by libc++ library
developers.

On all other platforms, this macro has an empty definition.
**_LIBCPP_METHOD_TEMPLATE_IMPLICIT_INSTANTIATION_VIS**
Mark a symbol as hidden so it will not be exported from shared libraries. This
is intended specifically for method templates of either classes marked with
`_LIBCPP_TYPE_VIS` or classes with an extern template instantiation
declaration marked with `_LIBCPP_EXTERN_TEMPLATE_TYPE_VIS`.
When building libc++ with hidden visibility, we want explicit template
instantiations to export members, which is consistent with existing Windows
behavior. We also want classes annotated with `_LIBCPP_TYPE_VIS` to export
their members, which is again consistent with existing Windows behavior.
Both these changes are necessary for clients to be able to link against a
libc++ DSO built with hidden visibility without encountering missing symbols.
An unfortunate side effect, however, is that method templates of classes
either marked `_LIBCPP_TYPE_VIS` or with extern template instantiation
declarations marked with `_LIBCPP_EXTERN_TEMPLATE_TYPE_VIS` also get default
visibility when instantiated. These methods are often implicitly instantiated
inside other libraries which use the libc++ headers, and will therefore end up
being exported from those libraries, since those implicit instantiations will
receive default visibility. This is not acceptable for libraries that wish to
control their visibility, and led to PR30642.
Consequently, all such problematic method templates are explicitly marked
either hidden (via this macro) or inline, so that they don't leak into client
libraries. The problematic methods were found by running
`bad-visibility-finder <https://github.com/smeenai/bad-visibility-finder>`_
against the libc++ headers after making `_LIBCPP_TYPE_VIS` and
`_LIBCPP_EXTERN_TEMPLATE_TYPE_VIS` expand to default visibility.

Mark a member function of a class template as visible and always inline. This

* r296729 - Remove std::num_get template methods which should be inline
These functions should never have had visible definitions in the dylib but
since they were previously not specified with 'inline' they accidentally
got emitted. This change is non-ABI breaking because every "linkage unit"
must contain its own definition.
