Eric Fiselier 7c0ed44db0 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		2018-07-22 02:00:53 +00:00
