* gh-57684: Add -P cmdline option and PYTHONSAFEPATH env var (#31542)Victor Stinner2022-05-051-1/+30
| | | | | | | | | | | | Add the -P command line option and the PYTHONSAFEPATH environment variable to not prepend a potentially unsafe path to sys.path. * Add sys.flags.safe_path flag. * Add PyConfig.safe_path member. * Programs/_bootstrap_python.c uses config.safe_path=0. * Update subprocess._optim_args_from_interpreter_flags() to handle the -P command line option. * Modules/getpath.py sets safe_path to 1 if a "._pth" file is present.

* gh-89479: Export _Py_GetSpecializationStats() internal function (#92011)Victor Stinner2022-04-281-1/+1
| | | | | | When Python is built with "./configure --enable-pystats" (if the Py_STATS macro is defined), the _Py_GetSpecializationStats() function must be exported, since it's used by the _opcode extension which is built as a shared library.

* gh-89373: _Py_Dealloc() checks tp_dealloc exception (#32357)Victor Stinner2022-04-211-0/+1
| | | | If Python is built in debug mode, _Py_Dealloc() now ensures that the tp_dealloc function leaves the current exception unchanged.

* bpo-45020: Default to using frozen modules unless running from source tree. ↵Eric Snow2021-10-161-1/+2
| | | | | | | (gh-28940) The default was "off". Switching it to "on" means users get the benefit of frozen stdlib modules without having to do anything. There's a special-case for running-in-source-tree, so contributors don't get surprised when their stdlib changes don't get used. https://bugs.python.org/issue45020

* bpo-45020: Add -X frozen_modules=[on|off] to explicitly control use of ↵Eric Snow2021-09-141-0/+9
| | | | | | | frozen modules. (gh-28320) Currently we freeze several modules into the runtime. For each of these modules it is essential to bootstrapping the runtime that they be frozen. Any other stdlib module that we later freeze into the runtime is not essential. We can just as well import from the .py file. This PR lets users explicitly choose which should be used, with the new "-X frozen_modules=[on|off]" CLI flag. The default is "off" for now. https://bugs.python.org/issue45020

| | | | | | | | This lease on this domain has lapsed. This not only makes these dead links, but a potential attack vector for readers of python.org as the domain can be obtained by an untrustworthy party. I considered redirecting these links to http://mingw-w64.org/ which is a maintained fork of mingw, but beyond my unfamiliarity with the exact level of compatibility, at the time of this PR that site had an expired cert and so is not much of a vulnerability fix.
