* closes bpo-37966: Fully implement the UAX #15 quick-check algorithm. (GH-15558)Greg Price2019-09-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-38022: IDLE: upgrade help.html to sphinx 2.x HTML5 output (GH-15664)Tal Einat2019-09-032-167/+229
| | | | | The HTML5 output from Sphinx 2.x adds '<p>' tags within list elements. Using a new prevtag attribute, ignore these instead of emitting unwanted '\n\n'. Also stop looking for 'first' classes on tags (no longer present) and fix the bug of double-spacing instead of single spacing after <pre> blocks.
* bpo-35771: IDLE: Fix flaky tool-tip hover delay tests (GH-15634)Tal Einat2019-09-033-48/+66
| | | | Extending the hover delay in test_tooltip should avoid spurious test_idle failures. One longer delay instead of two shorter delays results in a net speedup.

* bpo-37764: Fix infinite loop when parsing unstructured email headers. (GH-15239)Ashwin Ramaswami2019-08-313-3/+53
| | | | | | | | | | | | Fixes a case in which email._header_value_parser.get_unstructured hangs the system for some invalid headers. This covers the cases in which the header contains either: - a case without trailing whitespace - an invalid encoded word https://bugs.python.org/issue37764 This fix should also be backported to 3.7 and 3.8 https://bugs.python.org/issue37764

* bpo-37140: Fix StructUnionType_paramfunc() (GH-15612)Victor Stinner2019-08-301-6/+45
| | | | | | | | | | | | Fix a ctypes regression of Python 3.8. When a ctypes.Structure is passed by copy to a function, ctypes internals created a temporary object which had the side effect of calling the structure finalizer (__del__) twice. The Python semantics requires a finalizer to be called exactly once. Fix ctypes internals to no longer call the finalizer twice. Create a new internal StructParam_Type which is only used by _ctypes_callproc() to call PyMem_Free(ptr) on Py_DECREF(argument). StructUnionType_paramfunc() creates such object.

* bpo-37757: Disallow PEP 572 cases that expose implementation details (GH-15131)Nick Coghlan2019-08-253-38/+84
| | | | | | | | | | | | | | | - drop TargetScopeError in favour of raising SyntaxError directly as per the updated PEP 572 - comprehension iteration variables are explicitly local, but named expression targets in comprehensions are nonlocal or global. Raise SyntaxError as specified in PEP 572 - named expression targets in the outermost iterable of a comprehension have an ambiguous target scope. Avoid resolving that question now by raising SyntaxError. PEP 572 originally required this only for cases where the bound name conflicts with the iteration variable in the comprehension, but CPython can't easily restrict the exception to that case (as it doesn't know the target variable names when visiting the outermost iterator expression)

* bpo-37929: IDLE: avoid Squeezer-related config dialog crashes (GH-15452)Tal Einat2019-08-253-50/+26
| | | | | | | | | These were caused by keeping around a reference to the Squeezer instance and calling it's load_font() upon config changes, which sometimes happened even if the shell window no longer existed. This change completely removes that mechanism, instead having the editor window properly update its width attribute, which can then be used by Squeezer.
