Moreover, the following tests now check the child process exit code:
* test_os.PtyTests
* test_mailbox.test_lock_conflict()
* test_tempfile.test_process_awareness()
* test_uuid.testIssue8621()
* multiprocessing resource tracker tests
Capturing exceptions into names can lead to reference cycles though the __traceback__ attribute of the exceptions in some obscure cases that have been reported previously and fixed individually. As these variables are not used anyway, we can remove the binding to reduce the chances of creating reference cycles.
See for example GH-13135
uuid could try fallback methods that had no chance of working on a particular
platform, and this could cause spurious test failures, as well as degraded
performance as fallback options were tried and failed.
This fixes both the uuid module and its test's SkipUnless logic to use a
prefiltered list of techniques that may at least potentially work on that platform.
Patch by Michael Felt (aixtools).
``uuid.getnode()`` now preferentially returns universally administered MAC addresses if available, over locally administered MAC addresses. This makes a better guarantee for global uniqueness of UUIDs returned from ``uuid.uuid1()``. If only locally administered MAC addresses are available, the first such one found is returned.
Also improve internal code style by being explicit about ``return None`` rather than falling off the end of the function.
Improve the test robustness.
Improve UUID1 MAC address calculation and related tests.
There are two bits in the MAC address that are relevant to UUID1. The first is the locally administered vs. universally administered bit (second least significant of the first octet). Physical network interfaces such as ethernet ports and wireless adapters will always be universally administered, but some interfaces --such as the interface that MacBook Pros communicate with their Touch Bars-- are locally administered. The former are guaranteed to be globally unique, while the latter are demonstrably *not* globally unique and are in fact the same on every MBP with a Touch Bar. With this bit is set, the MAC is locally administered; with it unset it is universally administered.
The other bit is the multicast bit (least significant bit of the first octet). When no other MAC address can be found, RFC 4122 mandates that a random 48-bit number be generated. This randomly generated number *must* have the multicast bit set.
The improvements in uuid.py include:
* Preferentially return a universally administered MAC address, falling back to a locally administered address if none of the former can be found.
* Improve several coding style issues, such as adding explicit returns of None, using a more readable bitmask pattern, and assuming that the ultimate fallback, random MAC generation will not fail (and propagating any exception there instead of swallowing them).
Improvements in test_uuid.py include:
* Always testing the calculated MAC for universal administration, unless explicitly disabled (i.e. for the random case), or implicitly disabled due to running in the Travis environment. Travis test machines have *no* universally administered MAC address at the time of this writing.
* Document how comparison of UUID objects work
* Document str(uuid) returns the braceless standard form
* Add a test for comparison of a UUID object with a non-UUID object

The C function used by uuid.uuid4 is broken on
OSX 10.6 in that after os.fork() the parent and
child generate the same sequence of UUIDs.
This patch falls back to the the Python implementation
on OSX 10.6 or later.
Fixes issue #8621.

Fix for issues #3581, #1481 and #7650:
1. The assumptions in check_node() were too restrictive:
- Hardware addresses with universal_local_bit=1 are valid
(locally administered).
- Many of the tested functions (including uuid.getnode())
may return valid RFC 4122 random node IDs. These are pretty
much random 48-bit values with the multicast bit set to 1.
2. _unixdll_getnode() calls _uuid_generate_time(), which may be None
on some platforms. The resulting TypeError is now caught.

Change the UUID properties to use @property.
Change the UUID API so that .bytes and .bytes_le return, and the
corresponding arguments to __init__() require, values of type 'bytes'.
and .keys(), .items(), .values() return dict views.
The dict views aren't fully functional yet; in particular, they can't
be compared to sets yet. but they are useful as "iterator wells".
There are still 27 failing unit tests; I expect that many of these
have fairly trivial fixes, but there are so many, I could use help.
There's one major and one minor category still unfixed:
doctests are the major category (and I hope to be able to augment the
refactoring tool to refactor bona fide doctests soon);
other code generating print statements in strings is the minor category.
(Oh, and I don't know if the compiler package works.)
