Deprecate using the __int__() method in implicit conversions of Python numbers to C integers.
* Make timedelta return subclass types Previously timedelta would always return the `date` and `datetime` types, regardless of what it is added to. This makes it return an object of the type it was added to. * Add tests for timedelta arithmetic on subclasses * Make pure python timedelta return subclass types * Add test for fromtimestamp with tz argument * Add tests for subclass behavior in now * Add news entry. Fixes: bpo-32417 bpo-35364 * More descriptive variable names in tests Addresses Victor's comments
encoding='latin1' should be used for successful decoding.
* Use _PyUnicode_Copy in sanitize_isoformat_str
* Use repr in fromisoformat error message
This reverses commit 67b74a98b2 per Serhiy Storchaka's suggestion:
I suggested to use %R in the error message because including the raw
string can be confusing in the case of empty string, or string
containing trailing whitespaces, invisible or unprintable characters.
We agree that it is better to change both the C and pure Python versions
to use repr.
* Retain non-sanitized dtstr for error printing
This does not create an extra string, it just holds on to a reference to
the original input string for purposes of creating the error message.
* PEP 7 fixes to from_isoformat
* Separate handling of Unicode and other errors
In the initial implementation, errors other than encoding errors would
both raise an error indicating an invalid format, which would not be
true for errors like MemoryError.
* Drop needs_decref from _sanitize_isoformat_str
Instead _sanitize_isoformat_str returns a new reference, even to the
original string.
On Windows, passing a negative value to local results in an OSError because localtime_s on Windows does not support negative timestamps. Unfortunately this means that fold detection for timestamps between 0 and max_fold_seconds will result in this OSError since we subtract max_fold_seconds from the timestamp to detect a fold. However, since we know there haven't been any folds in the interval [0, max_fold_seconds) in any timezone, we can hackily just forego fold detection for this time range on Windows.
A datetime object d is aware if d.tzinfo is not None and d.tzinfo.utcoffset(d) does not return None. If d.tzinfo is None, or if d.tzinfo is not None but d.tzinfo.utcoffset(d) returns None, d is naive. This commit ensures that instances with non-None d.tzinfo, but d.tzinfo.utcoffset(d) returning None are treated as naive. In addition, C acceleration code will raise TypeError if d.tzinfo.utcoffset(d) returns an object with the type other than timedelta. * Updated the documentation. Assume that the term "naive" is defined elsewhere and remove the not entirely correct clarification. Thanks, Tim.
Since implementation of bpo-25283, the objects returned by time.localtime always have tm_zone and tm_gmtoff attributes. Remove code that anticipates their absence.
Closes bpo-15873.
* Closes issue bpo-5288: Allow tzinfo objects with sub-minute offsets. * bpo-5288: Implemented %z formatting of sub-minute offsets. * bpo-5288: Removed mentions of the whole minute limitation on TZ offsets. * bpo-5288: Removed one more mention of the whole minute limitation. Thanks @csabella! * Fix a formatting error in the docs * Addressed review comments. Thanks, @haypo.
