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.
The backport of ensurepip to 2.7.9 allows pip to optionally be installed
or upgraded using the bundled pip provided by the new ensurepip module.
The option can be specified persistently using the configure option:
./configure --with-ensurepip[=upgrade|install|no]
It can also be overridden on either the "install" or "altinstall" targets:
make [alt]install ENSUREPIP=[upgrade|install|no]
For Python 2, the default option is "no" (do not install pip).
because the Doc Makefile has been changed to no longer download sphinx
and its dependencies, build-installer.py now requires that there be an
externally-supplied sphinx-build available.
As of 2.7.8, the 32-bit-only installer will support OS X 10.5
and later systems as is currently done for Python 3.x installers.
For 2.7.7 only, we will provide three installers:
the legacy deprecated 10.3+ 32-bit-only format;
the newer 10.5+ 32-bit-only format;
and the unchanged 10.6+ 64-/32-bit format.
Although binary installers will no longer be available from
python.org as of 2.7.8, it will still be possible to build from
source on 10.3.9 and 10.4 systems if necessary.
requires them. Disable executable bits and shebang lines in test and
benchmark files in order to prevent using a random system python, and in
source files of modules which don't provide command line interface.
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.
_Qdoffs when compiling with an SDK of 10.7 or later. The OS X APIs they
wrap have long been deprecated and have now been removed with 10.7.
These modules were already empty for 64-bit builds and have been removed
in Python 3. (Original patch by Ronald Oussoren.)
OS X framework builds already created versioned symlinks for all
executables and scripts installed in the framework bin directory,
of the general form ${cmd} - ${cmd}2.7. The changes here add a
hierarchy of ${cmd} -> ${cmd}2 -> ${cmd}2.7. Per previous
practice, all of the links are created in the framework bin
directory for both the install and altinstall targets. This is
consistent with the long-standing recommendation to manage multiple
framework versions by adding and ordering framework bin directories
on $PATH. Also, per past practice, symlinks to all framework bin
entries are created in $prefix/bin (by default, /usr/local/bin)
for the install target and only versioned links are created for
altinstall, although the use of these links is not recommended
for framework builds and their installation is optional with
the standard OS X installers.
