bpo-32199: The getnode() ip getter now uses 'ip link' instead of 'ip link list' (GH-4696) 2017-12-07 12:59:13 +01:00

Fix a regression in uuid added in bpo-32107. (#4677)
uuid.get_node() always must return a stable result.
Also added a test for non-reproducibility of _random_getnode().
Original patch by Xavier de Gaye.

bpo-32107 - Improve MAC address calculation and fix test_uuid.py (#4600)
``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.

bpo-32107 - Better merge of #4494 (#4576)
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.

I didn't realize LC_ALL was an override, and I should have.  I tried to
make a test, but it is not clear that the LC variables actually affect
the strings that uuid is using to parse the command output.

  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.

Guido van Rossum 254348e201 Rename buffer -> bytearray. 2007-11-21 19:29:53 +00:00
Guido van Rossum 98297ee781 Merging the py3k-pep3137 branch back into the py3k branch.
No detailed change log; just check out the change log for the py3k-pep3137
branch.  The most obvious changes:

  - str8 renamed to bytes (PyString at the C level);
  - bytes renamed to buffer (PyBytes at the C level);
  - PyString and PyUnicode are no longer compatible.

I.e. we now have an immutable bytes type and a mutable bytes type.

The behavior of PyString was modified quite a bit, to make it more
bytes-like.  Some changes are still on the to-do list.
