* Mark files as executable that are meant as scripts. (GH-15354)Greg Price2019-09-093-0/+0
| | | | | | | | | | | | | | | | | | | | | | | | | This is the converse of GH-15353 -- in addition to plenty of scripts in the tree that are marked with the executable bit (and so can be directly executed), there are a few that have a leading `#!` which could let them be executed, but it doesn't do anything because they don't have the executable bit set. Here's a command which finds such files and marks them. The first line finds files in the tree with a `#!` line *anywhere*; the next-to-last step checks that the *first* line is actually of that form. In between we filter out files that already have the bit set, and some files that are meant as fragments to be consumed by one or another kind of preprocessor. $ git grep -l '^#!' \ | grep -vxFf <( \ git ls-files --stage \ | perl -lane 'print $F[3] if (!/^100644/)' \ ) \ | grep -ve '\.in$' -e '^Doc/includes/' \ | while read f; do head -c2 "$f" | grep -qxF '#!' \ && chmod a+x "$f"; \ done

| | | | | | | | | | | | * bpo-26185: Fix repr() on empty ZipInfo object It was failing on AttributeError due to inexistant but required attributes file_size and compress_size.

* bpo-37936: Avoid ignoring files that we actually do track. (GH-15451)Greg Price2019-09-091-0/+2
| | | | | | | | | | | | | | | | | | | | There were about 14 files that are actually in the repo but that are covered by the rules in .gitignore. Git itself takes no notice of what .gitignore says about files that it's already tracking... but the discrepancy can be confusing to a human that adds a new file unexpectedly covered by these rules, as well as to non-Git software that looks at .gitignore but doesn't implement this wrinkle in its semantics. (E.g., `rg`.) Several of these are from rules that apply more broadly than intended: for example, `Makefile` applies to `Doc/Makefile` and `Tools/freeze/test/Makefile`, whereas `/Makefile` means only the `Makefile` at the repo's root. And the `Modules/Setup` rule simply wasn't updated after 961d54c5c. https://bugs.python.org/issue37936

[1] https://sourceware.org/gdb/current/onlinedocs/gdb/Define.html And indeed when trying to use the gdbinit file with gdb 8.3, I get: .../cpython/Misc/gdbinit:17: Error in sourced command file: Undefined command: "pyo".

* closes bpo-37966: Fully implement the UAX #15 quick-check algorithm. (GH-15558)Greg Price2019-09-041-0/+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

| | | | | | | | | | | | 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.
