bpo-33671: efficient zero-copy for shutil.copy* functions (Linux, OSX and Win) (#7160) * have shutil.copyfileobj use sendfile() if possible * refactoring: use ctx manager * add test with non-regular file obj * emulate case where file size can't be determined * reference _copyfileobj_sendfile directly * add test for offset() at certain position * add test for empty file * add test for non regular file dst * small refactoring * leave copyfileobj() alone in order to not introduce any incompatibility * minor refactoring * remove old test * update docstring * update docstring; rename exception class * detect platforms which only support file to socket zero copy * don't run test on platforms where file-to-file zero copy is not supported * use tempfiles * reset verbosity * add test for smaller chunks * add big file size test * add comment * update doc * update whatsnew doc * update doc * catch Exception * remove unused import * add test case for error on second sendfile() call * turn docstring into comment * add one more test * update comment * add Misc/NEWS entry * get rid of COPY_BUFSIZE; it belongs to another PR * update doc * expose posix._fcopyfile() for OSX * merge from linux branch * merge from linux branch * expose fcopyfile * arg clinic for the win implementation * convert path type to path_t * expose CopyFileW * fix windows tests * release GIL * minor refactoring * update doc * update comment * update docstrings * rename functions * rename test classes * update doc * update doc * update docstrings and comments * avoid do import nt|posix modules if unnecessary * set nt|posix modules to None if not available * micro speedup * update description * add doc note * use better wording in doc * rename function using 'fastcopy' prefix instead of 'zerocopy' * use :ref: in rst doc * change wording in doc * add test to make sure sendfile() doesn't get called aymore in case it doesn't support file to file copies * move CopyFileW in _winapi and actually expose CopyFileExW instead * fix line endings * add tests for mode bits * add docstring * remove test file mode class; let's keep it for later when Istart addressing OSX fcopyfile() specific copies * update doc to reflect new changes * update doc * adjust tests on win * fix argument clinic error * update doc * OSX: expose copyfile(3) instead of fcopyfile(3); also expose flags arg to python * osx / copyfile: use path_t instead of char * do not set dst name in the OSError exception in order to remain consistent with platforms which cannot do that (e.g. linux) * add same file test * add test for same file * have osx copyfile() pre-emptively check if src and dst are the same, otherwise it will return immedialtey and src file content gets deleted * turn PermissionError into appropriate SameFileError * expose ERROR_SHARING_VIOLATION in order to raise more appropriate SameFileError * honour follow_symlinks arg when using CopyFileEx * update Misc/NEWS * expose CreateDirectoryEx mock * change C type * CreateDirectoryExW actual implementation * provide specific makedirs() implementation for win * fix typo * skeleton for SetNamedSecurityInfo * get security info for src path * finally set security attrs * add unit tests * mimick os.makedirs() behavior and raise if dst dir exists * set 2 paths for OSError object * set 2 paths for OSError object * expand windows test * in case of exception on os.sendfile() set filename and filename2 exception attributes * set 2 filenames (src, dst) for OSError in case copyfile() fails on OSX * update doc * do not use CreateDirectoryEx() in copytree() if source dir is a symlink (breaks test_copytree_symlink_dir); instead just create a plain dir and remain consistent with POSIX implementation * use bytearray() and readinto() * use memoryview() with bytearray() * refactoring + introduce a new _fastcopy_binfileobj() fun * remove CopyFileEx and other C wrappers * remove code related to CopyFileEx * Recognize binary files in copyfileobj() ...and use fastest _fastcopy_binfileobj() when possible * set 1MB copy bufsize on win; also add a global _COPY_BUFSIZE variable * use ctx manager for memoryview() * update doc * remove outdated doc * remove last CopyFileEx remnants * OSX - use fcopyfile(3) instead of copyfile(3) ...as an extra safety measure: in case src/dst are "exotic" files (non regular or living on a network fs etc.) we better fail on open() instead of copyfile(3) as we're not quite sure what's gonna happen in that case. * update doc

bpo-32689: Updates shutil.move to allow for Path objects to be used as source arg (GH-15326) Important work originally done by @emilyemorehouse two years ago and nearly ready to go in. This bug has affected many people and in some cases has been a dealbreaker to the adoption of the otherwise wonderful pathlib and PEP519. https://stackoverflow.com/questions/33625931/copy-file-with-pathlib-in-python. This adds the outstanding test request from that PR @vstinner (https://github.com/python/cpython/pull/5393). Test fails without the change, passes with it, along with every other test in test_shutil. Some variants were experimented with to make the one line change and the most performant one was picked. # Added Test for PathLike directory destination, the current fail case ``` Lib/test/test_shutil.py::TestMove::test_move_file_pathlike FAILED [100%] ============================================================== FAILURES =============================================================== __________________________________________________ TestMove.test_move_file_pathlike ___________________________________________________ self = <test.test_shutil.TestMove testMethod=test_move_file_pathlike> def test_move_file_pathlike(self): # Move a file to another location on the same filesystem. src = pathlib.Path(self.src_file) > self._check_move_file(src, self.dst_dir, self.dst_file) Lib/test/test_shutil.py:1563: _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Lib/test/test_shutil.py:1545: in _check_move_file shutil.move(src, dst) /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/shutil.py:562: in move real_dst = os.path.join(dst, _basename(src)) _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ path = PosixPath('/var/folders/r2/psq74t5x3nbfzlph8bh2pvdw0000gn/T/tmp9ie0wh9_/foo') def _basename(path): # A basename() variant which first strips the trailing slash, if present. # Thus we always get the last component of the path, even for directories. sep = os.path.sep + (os.path.altsep or '') > return os.path.basename(path.rstrip(sep)) E AttributeError: 'PosixPath' object has no attribute 'rstrip' /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/shutil.py:526: AttributeError ============================================== 1 failed, 102 deselected in 0.30 seconds =============================================== ``` After change: ``` ========================================================= test session starts ========================================================= platform darwin -- Python 3.7.4, pytest-5.0.1, py-1.8.0, pluggy-0.12.0 -- /Users/maxwellmckinnon/.venvs/TA3.7/bin/python3.7 cachedir: .pytest_cache rootdir: /Users/maxwellmckinnon/dev/cpython plugins: cov-2.7.1, mock-1.10.4 collected 103 items / 102 deselected / 1 selected Lib/test/test_shutil.py::TestMove::test_move_file_pathlike PASSED [100%] ============================================== 1 passed, 102 deselected in 0.06 seconds =============================================== ``` Running all the tests in test_shutil.py ``` ╰─ pytest Lib/test/test_shutil.py -v ========================================================= test session starts ========================================================= platform darwin -- Python 3.7.4, pytest-5.0.1, py-1.8.0, pluggy-0.12.0 -- /Users/maxwellmckinnon/.venvs/TA3.7/bin/python3.7 cachedir: .pytest_cache rootdir: /Users/maxwellmckinnon/dev/cpython plugins: cov-2.7.1, mock-1.10.4 collected 103 items Lib/test/test_shutil.py::TestShutil::test_chown PASSED [ 0%] Lib/test/test_shutil.py::TestShutil::test_copy PASSED [ 1%] ...

I'm not sure if the idea is for all these modules to strictly avoid circular dependencies. They are already using os.path which is just as much a citizen in 3.8 as pathlib right? e.g. `real_dst = os.path.join(dst, _basename(src))` becomes `real_dst = Path(dst) / Path(src).name` I've looked around and familiarized myself, and I now think importing pathlib here is fine. My only remaining concern is that of performance. Here's the performance difference for this step. ``` In [46]: %timeit real_dst = os.path.join("a/b/c", _basename('b/')) 2.71 µs ± 62.6 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each) In [47]: %timeit real_dst = Path("a/b/c") / Path('b/').name 12.4 µs ± 65.3 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each) ``` Is 10us significant or insignificant compared to the least expensive operation this function will do? I don't know. Let's find out. ``` In [55]: %timeit os.rename('/tmp/a/a.txt', '/tmp/a/b.txt'); os.rename('/tmp/a/b.txt', '/tmp/a/a.txt') 124 µs ± 2.18 µs per loop (mean ± std. dev. of 7 runs, 10000 loops each) ``` 62us to rename. 10us seems significant enough that we wouldn't want to favor the Path sugar suggestion. 16% speed decrease from adding the 10us. What do people think? I was hoping to get to use pathlib.Path here, but I suspect for this low level move, it should be as fast as possible, and 16% is not worth one line of sugary code to me. https://bugs.python.org/issue32689 Automerge-Triggered-By: @gvanrossum
