This issue covers various changes for the macOS installers provided via python.org for 3.7.0.
- Provide a provisional new installer variant for macOS 10.9 and later systems with 64-bit (x86_64) architecture only. Apple has made it known that future versions of macOS will only fully support 64-bit executables and some other third-party software suppliers have chosen 10.9 as their oldest supported system.
- Support **Tcl/Tk 8.6** with the 10.9 installer variant.
- Upgrade **OpenSSL** to 1.1.0g and **SQLite** to 3.22.0.
- The compiler name used for the interpreter build and for modules built with **Distutils / pip** is now _gcc_ rather than _gcc-4.2_. And extension module builds will no longer try to force use of an old SDK if present.
* Fix multiple typos in code comments
* Add spacing in comments (test_logging.py, test_math.py)
* Fix spaces at the beginning of comments in test_logging.py
Don't rebuild generated files based on file modification time
anymore, the action is now explicit. Replace "make touch"
with "make regen-all".
Changes:
* Remove "make touch", Tools/hg/hgtouch.py and .hgtouch
* Add a new "make regen-all" command to rebuild all generated files
* Add subcommands to only generate specific files:
- regen-ast: Include/Python-ast.h and Python/Python-ast.c
- regen-grammar: Include/graminit.h and Python/graminit.c
- regen-importlib: Python/importlib_external.h and Python/importlib.h
- regen-opcode: Include/opcode.h
- regen-opcode-targets: Python/opcode_targets.h
- regen-typeslots: Objects/typeslots.inc
* Rename PYTHON_FOR_GEN to PYTHON_FOR_REGEN
* pgen is now only built by by "make regen-grammar"
* Add $(srcdir)/ prefix to paths to source files to handle correctly
compilation outside the source directory
Note: $(PYTHON_FOR_REGEN) is no more used nor needed by "make"
default target building Python.
and link with a private copy of OpenSSL, like installers targeted
for 10.5 already do, since Apple has deprecated use of the system
OpenSSL and removed its header files from the Xcode 7 SDK. Note
that this configuration is not currently used to build any
python.org-supplied installers and that the private copy of
OpenSSL requires its own root certificates.
Among other issues, the Apple-supplied 0.9.7 libs for the 10.5 ABI cannot
verify newer SHA-256 certs as now used by python.org services. Document
in the installer ReadMe some of the certificate management issues that
users now need to be more concerned with due to PEP 476's enabling cert
verification by default. For now, continue to use the Apple-supplied
0.9.8 libs for the 10.6+ installer since they use Apple private APIs to
verify certificates using the system- and user-managed CA keychain stores.
Some third-party projects, such as matplotlib and PIL/Pillow,
depended on being able to build with Tcl and Tk frameworks in
/Library/Frameworks. They were unable to build with the built-in
Tcl/Tk and/or execute correctly.
Make it easier for users to make use of the backup _tkinter linked
with the third-party Tcl and Tk frameworks in /Library/Frameworks.
The two tkinter variants are now installed in separate directories
under a new lib-tkinter. This allows per-user selection by
manipulating sys.path, directly or with PYTHONPATH. If this
proves useful, we can supply a more convenient user interface
to supply the paths. For now, this remains somewhat experimental.

of OPT for special build options. By setting OPT, some compiler-specific
options like -fwrapv were overridden and thus not used, which could result
in broken interpreters when building with clang.
64-bit/32-bit installer for 10.6+. It is no longer necessary
to install a third-party version of Tcl/Tk 8.5 to work around the
problems in the Apple-supplied Tcl/Tk 8.5 shipped in OS X 10.6
and later releases.
