* gh-109653: Reduce import overhead of uuid module on Linux (#115160)Shantanu2024-03-061-1/+4
| | | | | | | | | | | | | | | | | | | This follows in the footsteps of #21586 This speeds up import uuid by about 6ms on Linux. Before: ``` λ hyperfine -w 4 "./python -c 'import uuid'" Benchmark 1: ./python -c 'import uuid' Time (mean ± σ): 20.4 ms ± 0.4 ms [User: 16.7 ms, System: 3.8 ms] Range (min … max): 19.6 ms … 21.8 ms 136 runs ``` After: ``` λ hyperfine -w 4 "./python -c 'import uuid'" Benchmark 1: ./python -c 'import uuid' Time (mean ± σ): 14.5 ms ± 0.3 ms [User: 11.5 ms, System: 3.2 ms] Range (min … max): 13.9 ms … 16.0 ms 175 runs ```

* gh-94684: uuid: support bytes in the name argument to uuid3/5 (#94709)MonadChains2023-03-231-2/+6
| | | RFC 4122 does not specify that name should be a string, so for completness the functions should also support a name given as a raw byte sequence.
* GH-88597: Rename uuid's new CLI args to be in line with uuidgen. (#101248)achhina2023-01-251-12/+16

* GH-88597: Added command line interface to UUID module. (#99463)achhina2023-01-221-0/+49
| | | | | | | | | | | | The `uuid` module now supports command line usage. ```python ❯ ./python.exe -m uuid 5f2d57b1-90e8-417c-ba5d-69b9b6f74289 ❯ ./python.exe -m uuid -h usage: uuid.py [-h] [-u {uuid1,uuid3,uuid4,uuid5}] [-ns NAMESPACE] [-n NAME] ... ```
* gh-98415: Fix uuid.getnode() ifconfig implementation (#98423)Chaim Sanders2022-11-021-2/+7
| | | | | | | | | The uuid.getnode() function has multiple implementations, tested sequentially. The ifconfig implementation was incorrect and always failed: fix it. In practice, functions of libuuid library are preferred, if available: uuid_generate_time_safe(), uuid_create() or uuid_generate_time(). Co-authored-by: Dong-hee Na <donghee.na92@gmail.com>

* bpo-9216: Add usedforsecurity to hashlib constructors (GH-16044)Christian Heimes2019-09-131-2/+5
| | | | | The usedforsecurity keyword only argument added to the hash constructors is useful for FIPS builds and similar restrictive environment with non-technical requirements that legacy algorithms be forbidden by their implementations without being explicitly annotated as not being used for any security related purposes. Linux distros with FIPS support benefit from this being standard rather than making up their own way(s) to do it. Contributed and Signed-off-by: Christian Heimes christian@python.org

* bpo-28009: Fix uuid SkipUnless logic to be based on platform programs ↵Michael Felt2019-06-151-11/+32
| | | | | | | | | | | | | capable of introspection (GH-12777) 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).
* bpo-35701: Added __weakref__ slot to uuid.UUID (GH-11570)David H2019-01-171-1/+1

* bpo-31784: Use time.time_ns() in uuid.uuid1() (GH-11189)Victor Stinner2018-12-181-2/+2
| | | | | uuid.uuid1() now calls time.time_ns() rather than int(time.time() * 1e9). Replace also int(nanoseconds/100) with nanoseconds // 100. Add an unit test.

* bpo-33542: Ignore DUID in uuid.get_node on Windows. (GH-6922)CtrlZvi2018-05-201-1/+1
| | | | | | uuid._ipconfig_getnode did not validate the maximum length of the value, so long as the value had the same type of formatting as a MAC address. This let it select DUIDs as MAC addresses. It now requires an exact length match.

* Fix a regression in uuid added in bpo-32107. (#4677)Serhiy Storchaka2017-12-041-2/+2
| | | | | 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)Barry Warsaw2017-11-281-11/+60
| | | | | | | | ``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)Barry Warsaw2017-11-271-11/+59
| | | | | | | | | | | | | | | | 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.
