* Add in-kernel copying support for Linux (sendfile64(2), copy_file_range(2)), FreeBSD 13 (copy_file_range(2)), MacOS (copyfile(2)), and Windows (CopyFileExA). * Fix macro name USE_COPY_FILE_RANGE. * Minor bugfixes for userspace fallback. * Fix linux sendfile64 bugs. * Remove some overzealous asserts. * Allow transmission-test-copy to take an optional argument for an external reference file. * Fix return value error of tr_sys_path_copy. * Use COPYFILE_ALL for Macs without COPYFILE_CLONE. * Add in-kernel file copying for several platforms. Numerous operating systems now have support for copying files directly in the kernel, which is generally more efficient than copying in a userspace read(2)/ write(2) loop. (This becomes particularly relevant for 4th gen PCI-E storage, which approaches the latency of DRAM.) For Linux I use sendfile64(2), and, for later kernels, copy_file_range(2). FreeBSD 13 will also support copy_file_range(2). MacOS has copyfile(2), and Windows has CopyFileExA. Operating systems lacking such a syscall continue to use the existing read(2)/write(2) loop. * Appease uncrustify. * Appease uncrustify. * copy-test: generate random content at run time. * copy-test: Stylistic changes and more check()s. * copy-test: files_are_identical should follow test idioms * tr_sys_path_copy: numerous tweaks as requested by review. * s/old file/source file; s/new file/destination file. * tr_sys_path_copy: handle win32 wide characters in paths. * Uncrustify. * test-copy: Use non-string create_file_with_contents. * tr_sys_path_copy: numerous fixes. Per review: generate test file content at runtime; tidy use of check(); fix style; re-measure file sizes in the copy; define a macro when the system does not provide it; use Unicode APIs on Windows; and fix documentation. * Updated as per comments. * Rebase kernel-copy changes onto 3.0 with gtest. * Undo irrelevant comment change. * Fix syntax error. * Use tr_malloc() instead of tr_valloc(). * Use EXPECT instead of TR_ASSERT in gtest. * Add error handling. * Acceptable coding style has changed again. Now it's camelCase. Also use nullptr instead of NULL, etc. * Fix east/west const. Co-authored-by: Mike Gelfand <mikedld@users.noreply.github.com> |
