示例1: LooseCachePath
VfsPath CCacheLoader::LooseCachePath(const VfsPath& sourcePath, const MD5& initialHash, u32 version)
{
CFileInfo fileInfo;
if (m_VFS->GetFileInfo(sourcePath, &fileInfo) < 0)
{
debug_warn(L"source file disappeared"); // this should never happen
return VfsPath();
}
u64 mtime = (u64)fileInfo.MTime() & ~1; // skip lowest bit, since zip and FAT don't preserve it
u64 size = (u64)fileInfo.Size();
// Construct a hash of the file data and settings.
MD5 hash = initialHash;
hash.Update((const u8*)&mtime, sizeof(mtime));
hash.Update((const u8*)&size, sizeof(size));
hash.Update((const u8*)&version, sizeof(version));
// these are local cached files, so we don't care about endianness etc
// Use a short prefix of the full hash (we don't need high collision-resistance),
// converted to hex
u8 digest[MD5::DIGESTSIZE];
hash.Final(digest);
std::wstringstream digestPrefix;
digestPrefix << std::hex;
for (size_t i = 0; i < 8; ++i)
digestPrefix << std::setfill(L'0') << std::setw(2) << (int)digest[i];
// Get the mod path
OsPath path;
m_VFS->GetRealPath(sourcePath, path);
// Construct the final path
return VfsPath("cache") / path_name_only(path.BeforeCommon(sourcePath).Parent().string().c_str()) / sourcePath.ChangeExtension(sourcePath.Extension().string() + L"." + digestPrefix.str() + m_FileExtension);
