* closes bpo-37966: Fully implement the UAX #15 quick-check algorithm. (GH-15558)Greg Price2019-09-041-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The purpose of the `unicodedata.is_normalized` function is to answer the question `str == unicodedata.normalized(form, str)` more efficiently than writing just that, by using the "quick check" optimization described in the Unicode standard in UAX #15. However, it turns out the code doesn't implement the full algorithm from the standard, and as a result we often miss the optimization and end up having to compute the whole normalized string after all. Implement the standard's algorithm. This greatly speeds up `unicodedata.is_normalized` in many cases where our partial variant of quick-check had been returning MAYBE and the standard algorithm returns NO. At a quick test on my desktop, the existing code takes about 4.4 ms/MB (so 4.4 ns per byte) when the partial quick-check returns MAYBE and it has to do the slow normalize-and-compare: $ build.base/python -m timeit -s 'import unicodedata; s = "\uf900"*500000' \ -- 'unicodedata.is_normalized("NFD", s)' 50 loops, best of 5: 4.39 msec per loop With this patch, it gets the answer instantly (58 ns) on the same 1 MB string: $ build.dev/python -m timeit -s 'import unicodedata; s = "\uf900"*500000' \ -- 'unicodedata.is_normalized("NFD", s)' 5000000 loops, best of 5: 58.2 nsec per loop This restores a small optimization that the original version of this code had for the `unicodedata.normalize` use case. With this, that case is actually faster than in master! $ build.base/python -m timeit -s 'import unicodedata; s = "\u0338"*500000' \ -- 'unicodedata.normalize("NFD", s)' 500 loops, best of 5: 561 usec per loop $ build.dev/python -m timeit -s 'import unicodedata; s = "\u0338"*500000' \ -- 'unicodedata.normalize("NFD", s)' 500 loops, best of 5: 512 usec per loop
* bpo-36543: Remove old-deprecated ElementTree features. (GH-12707)Serhiy Storchaka2019-09-011-0/+6
| | | | | Remove methods Element.getchildren(), Element.getiterator() and ElementTree.getiterator() and the xml.etree.cElementTree module.

* bpo-36917: Add default implementation of ast.NodeVisitor.visit_Constant(). ↵Serhiy Storchaka2019-08-261-0/+7
| | | | | | | (GH-15490) It emits a deprecation warning and calls corresponding method visit_Num(), visit_Str(), etc.
* bpo-34880: Add the LOAD_ASSERTION_ERROR opcode. (GH-15073)Zackery Spytz2019-08-251-0/+9

* bpo-37663: have venv activation scripts all consistently use __VENV_PROMPT__ ↵Brett Cannon2019-08-211-0/+15
| | | | | | | for prompt customization (GH-14941) The activation scripts generated by venv were inconsistent in how they changed the shell's prompt. Some used `__VENV_PROMPT__` exclusively, some used `__VENV_PROMPT__` if it was set even though by default `__VENV_PROMPT__` is always set and the fallback matched the default, and one ignored `__VENV_PROMPT__` and used `__VENV_NAME__` instead (and even used a differing format to the default prompt). This change now has all activation scripts use `__VENV_PROMPT__` only and relies on the fact that venv sets that value by default. The color of the customization is also now set in fish to the blue from the Python logo for as hex color support is built into that shell (much like PowerShell where the built-in green color is used).
* bpo-37834: Normalise handling of reparse points on Windows (GH-15231)Steve Dower2019-08-211-0/+21
| | | | | | | | | | bpo-37834: Normalise handling of reparse points on Windows * ntpath.realpath() and nt.stat() will traverse all supported reparse points (previously was mixed) * nt.lstat() will let the OS traverse reparse points that are not name surrogates (previously would not traverse any reparse point) * nt.[l]stat() will only set S_IFLNK for symlinks (previous behaviour) * nt.readlink() will read destinations for symlinks and junction points only bpo-1311: os.path.exists('nul') now returns True on Windows * nt.stat('nul').st_mode is now S_IFCHR (previously was an error)

* bpo-32912: Revert SyntaxWarning on invalid escape sequences. (GH-15195)Gregory P. Smith2019-08-101-5/+0
| | | | | | | | | | | | | | | | | | DeprecationWarning will continue to be emitted for invalid escape sequences in string and bytes literals just as it did in 3.7. SyntaxWarning may be emitted in the future. But per mailing list discussion, we don't yet know when because we haven't settled on how to do so in a non-disruptive manner. (Applies 4c5b6bac2408f879231c7cd38d67657dd4804e7c to the master branch).

* bpo-37444: Update differing exception between builtins and importlib (GH-14869)Ngalim Siregar2019-08-031-0/+20
| | | | | | | | | | Imports now raise `TypeError` instead of `ValueError` for relative import failures. This makes things consistent between `builtins.__import__` and `importlib.__import__` as well as using a more natural import for the failure. https://bugs.python.org/issue37444 Automerge-Triggered-By: @brettcannon

* bpo-37414: Remove sys.callstats() (GH-14398)Victor Stinner2019-06-261-0/+5
| | | | | Remove the undocumented sys.callstats() function. Since Python 3.7, it was deprecated and always returned None. It required a special build option CALL_PROFILE which was already removed in Python 3.7.
* bpo-37412: os.getcwdb() now uses UTF-8 on Windows (GH-14396)Victor Stinner2019-06-261-0/+5
| | | | | | | | | The os.getcwdb() function now uses the UTF-8 encoding on Windows, rather than the ANSI code page: see PEP 529 for the rationale. The function is no longer deprecated on Windows. os.getcwd() and os.getcwdb() now detect integer overflow on memory allocations. On Unix, these functions properly report MemoryError on memory allocation failure.
* bpo-37388: Development mode check encoding and errors (GH-14341)Victor Stinner2019-06-251-0/+9
| | | | | | | | | In development mode and in debug build, encoding and errors arguments are now checked on string encoding and decoding operations. Examples: open(), str.encode() and bytes.decode(). By default, for best performances, the errors argument is only checked at the first encoding/decoding error, and the encoding argument is sometimes ignored for empty strings.
* bpo-20443: _PyConfig_Read() gets the absolute path of run_filename (GH-14053)Victor Stinner2019-06-251-0/+8
| | | | | | | | | | | | Python now gets the absolute path of the script filename specified on the command line (ex: "python3 script.py"): the __file__ attribute of the __main__ module, sys.argv[0] and sys.path[0] become an absolute path, rather than a relative path. * Add _Py_isabs() and _Py_abspath() functions. * _PyConfig_Read() now tries to get the absolute path of run_filename, but keeps the relative path if _Py_abspath() fails. * Reimplement os._getfullpathname() using _Py_abspath(). * Use _Py_isabs() in getpath.c.
* Fix minor spelling error in What's new for Python 3.8 (GH-14371)Pablo Galindo2019-06-251-1/+1

| | | | | | | Remove sys.getcheckinterval() and sys.setcheckinterval() functions. They were deprecated since Python 3.2. Use sys.getswitchinterval() and sys.setswitchinterval() instead. Remove also check_interval field of the PyInterpreterState structure.

| | | | | | | * Rename PyImport_Cleanup() to _PyImport_Cleanup() and move it to the internal C API. Add 'tstate' parameters. * Remove documentation of _PyImport_Init(), PyImport_Cleanup(), _PyImport_Fini(). All three were documented as "For internal use only.".
* Document changes in PyNode_AddChild and PyParser_AddToken (GH-14214)Ivan Levkivskyi2019-06-191-0/+2
| | | I didn't find any entries in the docs about these functions, so I just mentioned them, in "What's New".
* bpo-37320: Remove openfp() of aifc, sunau and wave (GH-14169)Victor Stinner2019-06-171-3/+8
| | | | | aifc.openfp() alias to aifc.open(), sunau.openfp() alias to sunau.open(), and wave.openfp() alias to wave.open() have been removed. They were deprecated since Python 3.7.
* bpo-37194: Add PyObject_CallNoArgs() rationale (GH-14159)Victor Stinner2019-06-171-1/+4
| | | | Explain in the doc why PyObject_CallNoArgs() should be preferred over other existing ways to call a function without any arguments.
