* remove Frame, Trace and TraceStats classes
* add Metric class
* replace start_timer()/stop_timer() with a new Task class
* Task can now be scheduled using a threshold on the size of the traced memory,
and only called repeat times
* add DisplayTop.display() method
* a lot of other (minor) changes
I realised after the last round of reviews that a *big* chunk of the
rationale for this PEP was assumed knowledge on distutils-sig, and
this lead directly to the high rate of replies on python-dev that
just didn't get why the requested exemption to include the new
feature in Python 2.7.6 is so important.
The PEP now attempts to do a better job of bridging that gap, as
well as further expanding on how having the ``ensurepip`` module
fully public in older releases should actually make things *less*
confusing, rather than more, since it gives us a location to
explain the alternative fallback bootstrapping methods.
Combined update with changes from both Donald and I
- adjust the abstract to emphasise the fact this is first about
recommending pip as the official installer, and only then
about trying to ensure it is made readily available to users
- note in the rationale that this is a key stepping stone towards
decoupling the release cycle of the language from that of the
PyPI software distribution ecosystem
- expanded proposal overview (including explaining the logic that
leads from recommending pip to providing it by default)
- note the benefit of being able to test the bootstrap using the
existing buildbot fleet
- note the three known use cases for invoking ensurepip directly
- a little more detail on the required documentation updates
- be clear that easy_install *will* be installed by default, but
that problem will go away once pip eliminates their setuptools
dependency
- greatly expand on the rationale for including ensurepip in the
2.7 and 3.3 maintenance releases, including an explanation of
the origins of the current policy in the 2.2.x series, how the
current proposal differs from those, and why this shouldn't
open the floodgates to more requests for exemptions
- mention multiple commercial Python redistributors rather than
just the one
- clarify various issues in the recommendations for downstream
redistributors
- note the licenses for the bundled software
- explain rationale for not making this an installer-only change
in 2.7 and 3.3
- explain rationale for keeping the ensurepip module public in
2.7 and 3.3
- assorted cleanups to grammar and wording
- use the module name Antoine suggested
- list the five distinct parts of the proposal when
describing the implementation strategy
- note the bootstrap approach makes it easy to let people opt-out
- allow distros to redirect a global ensurepip invocation to the
system package manager
- decide the open questions in favour of the currently documented
approaches (i.e. no changes to uninstallation, update the
directory layout and PATH handling on Windows)
