* bpo-38321: Fix _testcapimodule.c warning (GH-16494)Victor Stinner2019-09-301-2/+2
| | | | | | | Fix the following warning: modules\_testcapimodule.c(6409): warning C4146: unary minus operator applied to unsigned type, result still unsigned
* Clear weakrefs in garbage found by the GC (#16495)Neil Schemenauer2019-09-302-0/+20
| | | | | Fix a bug due to the interaction of weakrefs and the cyclic garbage collector. We must clear any weakrefs in garbage in order to prevent their callbacks from executing and causing a crash.
* bpo-38321: Fix PyCStructUnionType_update_stgdict() warning (GH-16492)Victor Stinner2019-09-301-1/+1
| | | | | | bpo-22273, bpo-38321: Fix following warning: modules\_ctypes\stgdict.c(704): warning C4244: 'initializing': conversion from 'Py_ssize_t' to 'int', possible loss of data
* bpo-38321: Fix _asynciomodule.c compiler warning (GH-16493)Victor Stinner2019-09-301-1/+0
| | | | | | | | | bpo-38248, bpo-38321: Fix warning: modules\_asynciomodule.c(2667): warning C4102: 'set_exception': unreferenced label The related goto has been removed by commit edad4d89e357c92f70c0324b937845d652b20afd.
* bpo-38322: Fix gotlandmark() of PC/getpathp.c (GH-16489)Victor Stinner2019-09-301-8/+6
| | | | | | Write the filename into a temporary buffer instead of reusing prefix. The problem is that join() modifies prefix inplace. If prefix is not normalized, join() can make prefix shorter and so gotlandmark() does modify prefix instead of returning it unmodified.
* bpo-38304: Fix PyConfig usage in python_uwp.cpp (GH-16487)Victor Stinner2019-09-301-1/+7
| | | | | * Set PyPreConfig.struct_size and PyConfig.struct_size as required by the API. * PyPreConfig_InitPythonConfig() can now fail: check PyStatus result.

| | | | | | | | | Fix warnings options priority: PyConfig.warnoptions has the highest priority, as stated in the PEP 587. * Document options order in PyConfig.warnoptions documentation. * Make PyWideStringList_INIT macro private: replace "Py" prefix with "_Py". * test_embed: add test_init_warnoptions().

* bpo-38115: Deal with invalid bytecode offsets in lnotab (GH-16079)T. Wouters2019-09-284-2/+77
| | | | | | | | | | Document that lnotab can contain invalid bytecode offsets (because of terrible reasons that are difficult to fix). Make dis.findlinestarts() ignore invalid offsets in lnotab. All other uses of lnotab in CPython (various reimplementations of addr2line or line2addr in Python, C and gdb) already ignore this, because they take an address to look for, instead. Add tests for the result of dis.findlinestarts() on wacky constructs in test_peepholer.py, because it's the easiest place to add them.
* bpo-38216, bpo-36274: Allow subclasses to separately override validation and ↵Jason R. Coombs2019-09-283-9/+51

This makes overriding just that simpler. Also, don't use the := operator to make backporting easier. * Add a news entry. * _prepare_path_encoding -> _encode_prepared_path() * Once again separate the path validation and request encoding, drastically simplifying the behavior. Drop the guarantee that all processing happens in _prepare_path.
* bpo-38304: Add PyConfig.struct_size (GH-16451)Victor Stinner2019-09-2813-60/+350
| | | | | | | | | | | | | | | | | Add a new struct_size field to PyPreConfig and PyConfig structures to allow to modify these structures in the future without breaking the backward compatibility. * Replace private _config_version field with public struct_size field in PyPreConfig and PyConfig. * Public PyPreConfig_InitIsolatedConfig() and PyPreConfig_InitPythonConfig() return type becomes PyStatus, instead of void. * Internal _PyConfig_InitCompatConfig(), _PyPreConfig_InitCompatConfig(), _PyPreConfig_InitFromConfig(), _PyPreConfig_InitFromPreConfig() return type becomes PyStatus, instead of void. * Remove _Py_CONFIG_VERSION * Update the Initialization Configuration documentation.

Add more checks to skip OpenSSL implementations when a strict crypto policy is active. Use EVP_DigestInit_ex() instead of EVP_DigestInit() to initialize the EVP context.

* bpo-38112: Compileall improvements (GH-16012)Lumír 'Frenzy' Balhar2019-09-264-39/+386
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * Raise the limit of maximum path depth to actual recursion limit * Add posibilities to adjust a path compiled in .pyc file. Now, you can: - Strip a part of path from a beggining of path into compiled file example "-s /test /test/build/real/test.py" → "build/real/test.py" - Append some new path to a beggining of path into compiled file example "-p /boo real/test.py" → "/boo/real/test.py" You can also use both options in the same time. In that case, striping is done before appending. * Add a possibility to specify multiple optimization levels Each optimization level then leads to separated compiled file. Use `action='append'` instead of `nargs='+'` for the -o option. Instead of `-o 0 1 2`, specify `-o 0 -o 1 -o 2`. It's more to type, but much more explicit. * Add a symlinks limitation feature This feature allows us to limit byte-compilation of symbolic links if they are pointing outside specified dir (build root for example).

Fix also test_init_setpath() and test_init_setpythonhome() on macOS: use self.test_exe as the executable (and base_executable), rather than shutil.which('python3').
