From 5ca3aee00ac3ac1a906de68c216907a7b41825fe Mon Sep 17 00:00:00 2001 From: JosJuice Date: Thu, 29 Jun 2017 11:20:38 +0200 Subject: FileUtil: Add a class for Exists/IsDirectory/GetSize Some code was calling more than one of these functions in a row (in particular, FileUtil.cpp itself did it a lot...), which is a waste since it's possible to call stat a single time and then read all three values from the stat struct. This commit adds a File::FileInfo class that calls stat once on construction and then lets Exists/IsDirectory/GetSize be executed very quickly. The performance improvement mostly matters for functions that can be handling a lot of files, such as File::ScanDirectoryTree. I've also done some cleanup in code that uses these functions. For instance, some code had checks like !Exists() || !IsDirectory(), which is functionally equivalent to !IsDirectory(), and some code was using File::GetSize even though there was an IOFile object that the code could call GetSize on. --- Source/Core/VideoCommon/TextureCacheBase.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'Source/Core/VideoCommon/TextureCacheBase.cpp') diff --git a/Source/Core/VideoCommon/TextureCacheBase.cpp b/Source/Core/VideoCommon/TextureCacheBase.cpp index c61fa1fe5e..5c7c61695a 100644 --- a/Source/Core/VideoCommon/TextureCacheBase.cpp +++ b/Source/Core/VideoCommon/TextureCacheBase.cpp @@ -424,7 +424,7 @@ void TextureCacheBase::DumpTexture(TCacheEntry* entry, std::string basename, uns std::string szDir = File::GetUserPath(D_DUMPTEXTURES_IDX) + SConfig::GetInstance().GetGameID(); // make sure that the directory exists - if (!File::Exists(szDir) || !File::IsDirectory(szDir)) + if (!File::IsDirectory(szDir)) File::CreateDir(szDir); if (level > 0) -- cgit v1.2.3
