[issue13936] datetime.time(0, 0, 0) evaluates to False despite being a valid time
Andreas Pelme added the comment: I agree with Danilo and Shai -- this behavior very surprising. I deal with datetimes a lot, and this bug has bitten me a number of times. I cannot really think of a single case where "if timeobj:" is useful with the current behavior. It results in a check for "is timeobj midnight or false?" Would that ever be useful in practice? If you are indeed checking for midnight, surely "if timeobj == time(0, 0):" would be the most explicit and obvious way to do it? -- nosy: +Andreas.Pelme ___ Python tracker <http://bugs.python.org/issue13936> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue5033] setup.py crashes if sqlite version contains 'beta'
Andreas Pelme added the comment: This bug still exists in 2.7 and 3.4. If SQLITE_VERSION in sqlite3.h (/usr/include/sqlite3.h on Mac OS) ends with beta, such as #define SQLITE_VERSION"3.7.12beta" make will fail. The regex changed suggested above fixes this. The attached patch contains that fix and makes the build work. -- keywords: +patch nosy: +Andreas.Pelme Added file: http://bugs.python.org/file29171/issue5033.patch ___ Python tracker <http://bugs.python.org/issue5033> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue17176] Document imp.NullImporter is NOT used anymore by import
Andreas Pelme added the comment: This seems like an oversight from http://bugs.python.org/issue15473 The release notes for 3.3 added a note about this: "Because None is now inserted into sys.path_importer_cache, if you are clearing out entries in the dictionary of paths that do not have a finder, you will need to remove keys paired with values of None and imp.NullImporter to be backwards-compatible. This will lead to extra overhead on older versions of Python that re-insert None into sys.path_importer_cache where it repesents the use of implicit finders, but semantically it should not change anything." But the relevant docs for NullImporter (http://docs.python.org/2/library/imp.html#imp.NullImporter) and sys.path_importer_cache (http://docs.python.org/2/library/sys.html#sys.path_importer_cache) did not get updated. We have verified that the release notes in 3.4 is correct, and NullImporter is never used. We are however not sure about the correct wording for the documentation fix. -- nosy: +Andreas.Pelme ___ Python tracker <http://bugs.python.org/issue17176> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
