From: Ville Skyttä Date: Sat, 10 Jun 2023 16:54:21 +0000 (+0300) Subject: Use aware datetimes to represent UTC (#3728) X-Git-Url: https://git.madduck.net/etc/vim.git/commitdiff_plain/898915d5569f503c278ef53cb6f10e003034943c?ds=sidebyside;hp=3aad6e385bfbd4348b2e13695cb6741806951160 Use aware datetimes to represent UTC (#3728) Avoids a Python 3.12 deprecation warning. Subtle difference: previously, timestamps in diff filenames had the `+0000` separated from the timestamp by space. With this, the space is there no more, and there is a colon, as in `+00:00`. --- diff --git a/CHANGES.md b/CHANGES.md index fb3dea8..658faad 100644 --- a/CHANGES.md +++ b/CHANGES.md @@ -42,6 +42,8 @@ +- Use aware UTC datetimes internally, avoids deprecation warning on Python 3.12 (#3728) + ### _Blackd_ diff --git a/docs/usage_and_configuration/the_basics.md b/docs/usage_and_configuration/the_basics.md index 48619c6..6f3a3cf 100644 --- a/docs/usage_and_configuration/the_basics.md +++ b/docs/usage_and_configuration/the_basics.md @@ -164,8 +164,8 @@ If you'd like colored diffs, you can enable them with `--color`. ```console $ black test.py --diff ---- test.py 2021-03-08 22:23:40.848954 +0000 -+++ test.py 2021-03-08 22:23:47.126319 +0000 +--- test.py 2021-03-08 22:23:40.848954+00:00 ++++ test.py 2021-03-08 22:23:47.126319+00:00 @@ -1 +1 @@ -print ( 'hello, world' ) +print("hello, world") diff --git a/src/black/__init__.py b/src/black/__init__.py index 8a759aa..dbcb559 100644 --- a/src/black/__init__.py +++ b/src/black/__init__.py @@ -7,7 +7,7 @@ import tokenize import traceback from contextlib import contextmanager from dataclasses import replace -from datetime import datetime +from datetime import datetime, timezone from enum import Enum from json.decoder import JSONDecodeError from pathlib import Path @@ -807,7 +807,7 @@ def format_file_in_place( elif src.suffix == ".ipynb": mode = replace(mode, is_ipynb=True) - then = datetime.utcfromtimestamp(src.stat().st_mtime) + then = datetime.fromtimestamp(src.stat().st_mtime, timezone.utc) header = b"" with open(src, "rb") as buf: if mode.skip_source_first_line: @@ -828,9 +828,9 @@ def format_file_in_place( with open(src, "w", encoding=encoding, newline=newline) as f: f.write(dst_contents) elif write_back in (WriteBack.DIFF, WriteBack.COLOR_DIFF): - now = datetime.utcnow() - src_name = f"{src}\t{then} +0000" - dst_name = f"{src}\t{now} +0000" + now = datetime.now(timezone.utc) + src_name = f"{src}\t{then}" + dst_name = f"{src}\t{now}" if mode.is_ipynb: diff_contents = ipynb_diff(src_contents, dst_contents, src_name, dst_name) else: @@ -868,7 +868,7 @@ def format_stdin_to_stdout( write a diff to stdout.
