[issue12627] Implement PEP 394: The python Command on Unix-Like Systems
Ned Deily n...@acm.org added the comment:
Changeset 499796937b7a implements PEP 394 for OS X framework builds on Python
2.7. 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. This is all accomplished in some additional
targets in Mac/Makefile which are automatically added by configure for
framework builds and supersede the standard processing in the main Makefile
bininstall and altbininstall targets. The changes here add the additional
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.
No changes are needed for 3.2 or 3.3 at this time. Although the Mac/Makefile
targets don't quite create all of the versioned links in $prefix/bin, the
installer build script does the right thing by creating symlinks to everything
in the fw bin directory.
In many respects, the current situation for framework builds is less than
ideal, with duplicated code, vestigial links, and, more importantly, a clumsy
and non-transparent method for managing multiple versions. I intend to revisit
this area prior to Python 3.3 feature code cutoff as a separate issue.

[issue12627] Implement PEP 394: The python Command on Unix-Like Systems
Nick Coghlan ncogh...@gmail.com added the comment: No automatic link, since I neglected to mention the issue number in the checkin messages: 2.7: http://hg.python.org/cpython/rev/a65a71aa9436 3.3: http://hg.python.org/cpython/rev/dc721f28f168 I deliberately *didn't* make the change in 3.2. As the choice of symlink vs hardlink is really more cosmetic than consequential, it didn't feel like an appropriate change to make in a maintenance release without a compelling reason (introducing a *new* link meant we had such a reason for 2.7, but that's not applicable to 3.2). Handing the issue over to Ned to confirm the OS X framework builds align with the PEP. -- assignee: - ned.deily stage: patch review - needs patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12627 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue12627] Implement PEP 394: The python Command on Unix-Like Systems
Nick Coghlan ncogh...@gmail.com added the comment: I removed the 3.3 patch, since all the previous version did was change symbolic links to hard links, and the latest round of discussions favoured retaining the symlinks since they're much easier to introspect. However, it turns out there is still one change needed for 3.3 - updating the current python3 hardlink to make it a symlink instead. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12627 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Nick Coghlan ncogh...@gmail.com added the comment: Actually, the Python 3 Makefile.pre.in is currently broken if $(EXE) is ever non-empty - in a few places it uses $(PYTHON)$(VERSION)$(EXE) and $(PYTHON)3$(EXE). Those are wrong, because the definition of $(PYTHON) at the top of the file is python$(EXE) Instead, they need to be written as python$(VERSION)$(EXE) and python3$(EXE) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12627 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Kerrick Staley m...@kerrickstaley.com added the comment: Here is a patch that will update the Makefile.pre.in file for 2.7, causing it to install python2 and python2-config when run with make install (or just make bininstall). This does not update any documentation. Also, it appears that Idle and PyDoc are not installed by the 2.7 Makefile, so I didn't do anything about those, even though the PEP mentions them. -- keywords: +patch Added file: http://bugs.python.org/file22737/version27_links.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12627 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
