Functions | |
void | fs::RewriteFileContents (engine::TaskProcessor &async_tp, const std::string &path, std::string_view contents) |
Rewrite file contents asynchronously It doesn't provide strict atomic guarantees. If you need them, use fs::RewriteFileContentsAtomically . | |
void | fs::Rename (engine::TaskProcessor &async_tp, const std::string &source, const std::string &destination) |
Renames existing file. | |
void | fs::RewriteFileContentsAtomically (engine::TaskProcessor &async_tp, const std::string &path, std::string_view contents, boost::filesystem::perms perms) |
Rewrite file contents atomically Write contents to temporary file in the same directory, then atomically replaces the destination file with the temporary file. Effectively does write()+sync()+rename()+sync(directory). It does both sync(2) for file and on the directory, so after successful return the file must persist on the filesystem. | |
void | fs::Chmod (engine::TaskProcessor &async_tp, const std::string &path, boost::filesystem::perms perms) |
Change file mode. | |
bool | fs::RemoveSingleFile (engine::TaskProcessor &async_tp, const std::string &path) |
Remove existing file. | |
void | fs::CreateDirectories (engine::TaskProcessor &async_tp, std::string_view path, boost::filesystem::perms perms) |
Create directory and all necessary parent elements. Condition when path already exists and is a directory treated as "success" and no exception is thrown. | |
