libcxx: Rename .hpp files in libcxx/test/support to .h LLVM uses .h as its extension for header files. Files renamed using: for f in libcxx/test/support/*.hpp; do git mv $f ${f%.hpp}.h; done References to the files updated using: for f in $(git diff master | grep 'rename from' | cut -f 3 -d ' '); do a=$(basename $f); echo $a; rg -l $a libcxx | xargs sed -i '' "s/$a/${a%.hpp}.h/"; done HPP include guards updated manually using: for f in $(git diff master | grep 'rename from' | cut -f 3 -d ' '); do echo ${f%.hpp}.h ; done | xargs mvim Differential Revision: https://reviews.llvm.org/D66104 llvm-svn: 369481

Add Filesystem TS -- Complete 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

[libc++] Implement Directory Entry Caching -- Sort of. Summary: This patch implements directory_entry caching *almost* as specified in P0317r1. However, I explicitly chose to deviate from the standard as I'll explain below. The approach I decided to take is a fully caching one. When `refresh()` is called, the cache is populated by calls to `stat` and `lstat` as needed. During directory iteration the cache is only populated with the `file_type` as reported by `readdir`. The cache can be in the following states: * `_Empty`: There is nothing in the cache (likely due to an error) * `_IterSymlink`: Created by directory iteration when we walk onto a symlink only the symlink file type is known. * `_IterNonSymlink`: Created by directory iteration when we walk onto a non-symlink. Both the regular file type and symlink file type are known. * `_RefreshSymlink` and `_RefreshNonSymlink`: A full cache created by `refresh()`. This case includes dead symlinks. * `_RefreshSymlinkUnresolved`: A partial cache created by refresh when we fail to resolve the file pointed to by a symlink (likely due to permissions). Symlink attributes are cached, but attributes about the linked entity are not. As mentioned, this implementation purposefully deviates from the standard. According to some readings of the specification, and the Windows filesystem implementation, the constructors and modifiers which don't pass an `error_code` must throw when the `directory_entry` points to a entity which doesn't exist. or when attribute resolution fails for another reason. @BillyONeal has proposed a more reasonable set of requirements, where modifiers other than refresh ignore errors. This is the behavior libc++ currently implements, with the expectation some form of the new language will be accepted into the standard. Some additional semantics which differ from the Windows implementation: 1. `refresh` will not throw when the entry doesn't exist. In this case we can still meet the functions specification, so we don't treat it as an error. 2. We don't clear the path name when a constructor fails via refresh (this will hopefully be changed in the standard as well). It should be noted that libstdc++'s current implementation has the same behavior as libc++, except for point (2). If the changes to the specification don't get accepted, we'll be able to make the changes later.

Implement a better copy_file. This patch improves both the performance, and the safety of the copy_file implementation. The performance improvements are achieved by using sendfile on Linux and copyfile on OS X when available. The TOCTOU hardening is achieved by opening the source and destination files and then using fstat to check their attributes to see if we can copy them. Unfortunately for the destination file, there is no way to open it without accidentally creating it, so we first have to use stat to determine if it exists, and if we should copy to it. Then, once we're sure we should try to copy, we open the dest file and ensure it names the same entity we previously stat'ed. llvm-svn: 337649

Add Filesystem TS -- Complete 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
