From c978f3144cae1a59a612088aa99752bc74cf9e03 Mon Sep 17 00:00:00 2001 From: Morph <39850852+Morph1984@users.noreply.github.com> Date: Fri, 11 Jun 2021 02:20:36 -0400 Subject: common: fs: Use the normal directory iterator in *Recursively functions MSVC's implementation of recursive_directory_iterator throws an exception on an error despite a std::error_code being passed into its constructor. This is most likely a bug in MSVC's implementation since directory_iterator does not throw an exception on an error. We can replace the usage of recursive_directory_iterator for now until MSVC fixes their implementation of it. --- src/common/fs/fs.cpp | 18 ++++++++++++++++-- 1 file changed, 16 insertions(+), 2 deletions(-) diff --git a/src/common/fs/fs.cpp b/src/common/fs/fs.cpp index d492480d9..d3159e908 100644 --- a/src/common/fs/fs.cpp +++ b/src/common/fs/fs.cpp @@ -321,7 +321,8 @@ bool RemoveDirContentsRecursively(const fs::path& path) { std::error_code ec; - for (const auto& entry : fs::recursive_directory_iterator(path, ec)) { + // TODO (Morph): Replace this with recursive_directory_iterator once it's fixed in MSVC. + for (const auto& entry : fs::directory_iterator(path, ec)) { if (ec) { LOG_ERROR(Common_Filesystem, "Failed to completely enumerate the directory at path={}, ec_message={}", @@ -337,6 +338,12 @@ bool RemoveDirContentsRecursively(const fs::path& path) { PathToUTF8String(entry.path()), ec.message()); break; } + + // TODO (Morph): Remove this when MSVC fixes recursive_directory_iterator. + // recursive_directory_iterator throws an exception despite passing in a std::error_code. + if (entry.status().type() == fs::file_type::directory) { + return RemoveDirContentsRecursively(entry.path()); + } } if (ec) { @@ -475,7 +482,8 @@ void IterateDirEntriesRecursively(const std::filesystem::path& path, std::error_code ec; - for (const auto& entry : fs::recursive_directory_iterator(path, ec)) { + // TODO (Morph): Replace this with recursive_directory_iterator once it's fixed in MSVC. + for (const auto& entry : fs::directory_iterator(path, ec)) { if (ec) { break; } @@ -495,6 +503,12 @@ void IterateDirEntriesRecursively(const std::filesystem::path& path, break; } } + + // TODO (Morph): Remove this when MSVC fixes recursive_directory_iterator. + // recursive_directory_iterator throws an exception despite passing in a std::error_code. + if (entry.status().type() == fs::file_type::directory) { + IterateDirEntriesRecursively(entry.path(), callback, filter); + } } if (callback_error || ec) { -- cgit v1.2.3
