The previous implementation used execv(2) to run the real interpreter, which means that
you cannot use the arch(1) tool to select the architecture you want to use for a
universal build because that only affects the python/pythonw wrapper and not the actual
interpreter.
The new version uses posix_spawnv with a number of OSX-specific options that ensure that
the real interpreter is started using the same CPU architecture as the wrapper, and that
means that 'arch -ppc python' now actually works.
I've also changed the way that the wrapper looks for the framework: it is now linked to
the framework rather than hardcoding the framework path. This should make it easier to
provide pythonw support in tools like virtualenv.
self-test. Because of a change to the way tracebacks are printed,
this self-test was failing. The test is run (and passes) during normal
regression testing. So instead of running the failing self-test this
patch makes doctest emit a usage message. This is better behavior anyway
since passing in arguments is the real reason to run doctest as a command.

any errors that might occur during coercion of the left operand and
turning them into a TypeError with a message text that was confusing in
the given context. This patch lets any errors through, as was already
done during coercion of the right hand side.
This is for consistency with imitation file objects like StringIO and BytesIO.
This commit also adds a few tests, where they were lacking for concerned
methods.
default.
TarFile's errorlevel argument controls how errors are
handled that occur during extraction. There are three
possible levels 0, 1 and 2. If errorlevel is set to 1 or 2
fatal errors (e.g. a full filesystem) are raised as
exceptions. If it is set to 0, which is the default value,
extraction errors are suppressed, and error messages are
written to the debug log instead. But, if the debug log is
not activated, which is the default as well, all these
errors go unnoticed.
The original intention was to imitate GNU tar which tries
to extract as many members as possible instead of stopping
on the first error. It turns out that this is no good
default behaviour for a tar library. This patch simply
changes the default value for the errorlevel argument from
0 to 1, so that fatal extraction errors are raised as
EnvironmentError exceptions.
missing proper end-of-line termination. Patch and tests by
Scott Dial. The new tests include a test harness which will
make it easier to add additional tests.
