Implement

2018-07-27T03:07:09+00:00

This patch implements the header and uses that to provide . Unlike other standard headers, the symbols needed for have not yet been placed in libc++.so. Instead they live in the new libc++fs.a library. Users of filesystem are required to link this library. (Also note that libc++experimental no longer contains the definition of , which now requires linking libc++fs). The reason for keeping out of the dylib for now is that it's still somewhat experimental, and the possibility of requiring an ABI breaking change is very real. In the future the symbols will likely be moved into the dylib, or the dylib will be made to link libc++fs automagically). Note that moving the symbols out of libc++experimental may break user builds until they update to -lc++fs. This should be OK, because the experimental library provides no stability guarantees. However, I plan on looking into ways we can force libc++experimental to automagically link libc++fs. In order to use a single implementation and set of tests for , it has been placed in a special `__fs` namespace. This namespace is inline in C++17 onward, but not before that. As such implementation is available in C++11 onward, but no filesystem namespace is present "directly", and as such name conflicts shouldn't occur in C++11 or C++14. llvm-svn: 338093

Make filesystem tests generic between experimental and std versions.

2018-03-26T05:46:57+00:00

As I move towards implementing std::filesystem, there is a need to make the existing tests run against both the std and experimental versions. Additionally, it's helpful to allow running the tests against other implementations of filesystem. This patch converts the test to easily target either. First, it adds a filesystem_include.hpp header which is soley responsible for selecting and including the correct implementation. Second, it converts existing tests to use this header instead of including filesystem directly. llvm-svn: 328475

Implement LWG 2937 - equivalent("dne", "exists") is not an error

2017-07-05T03:37:05+00:00

This patch speculatively implements the PR for LWG 2937, which fixes two issues with equivalent. (1) It makes equivalent("dne", "exists") an error. Previously only equivalent("dne", "dne") was an error and the former case was not (it returned false). Now equivalent reports an error when either input doesn't exist. (2) It makes equivalent(p1, p2) well-formed when `is_other(p1) && is_other(p2)`. Previously this was an error, but there is seemingly no reason why it should be on POSIX system. llvm-svn: 307117

Add Filesystem TS -- Complete

2016-06-17T19:46:40+00:00

Add the completed std::experimental::filesystem implementation and tests. The implementation supports C++11 or newer. The TS is built as part of 'libc++experimental.a'. Users of the TS need to manually link this library. Building and testing the TS can be disabled using the CMake option '-DLIBCXX_ENABLE_FILESYSTEM=OFF'. Currently 'libc++experimental.a' is not installed by default. To turn on the installation of the library use '-DLIBCXX_INSTALL_EXPERIMENTAL_LIBRARY=ON'. llvm-svn: 273034
