Issue2071

Steps to reproduce:

Jython 2.7b1+ (, May 9 2013, 17:33:05) 
[Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)] on java1.7.0_25
Type "help", "copyright", "credits" or "license" for more information.
>>> import datetime
>>> d = datetime.datetime.now()
>>> d.strftime("%H:%M:%S.%f")
'17:47:35.%f'


Expected results:

Python 2.7.5 (default, Jul 12 2013, 16:58:06) 
[GCC 4.8.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import datetime
>>> d = datetime.datetime.now()
>>> d.strftime("%H:%M:%S.%f")
'17:48:32.770720'


Similar to issue1689, except that "%f" is part of datetime library in Python 2.7.

Related to issue 1964 [1]?

Nevermind. Similar issue, but completely different code paths.

Attaching a patch that includes a preprocessing step in _wrap_strftime() to include "%f".

$ ./dist/bin/jython -c "import datetime; d = datetime.datetime.now(); print d.strftime('%H:%M:%S.%f')"
18:11:32.289000

Patch + re-enabling unittest that would have caught this.

I'll take this one to evaluate. Thanks for submitting it.

Hmmm, we ought not to skip those other tests silently. I think the right thing to do here is bring on the test_datetime.py from Python 2.7 and skip noisily the tests Jython can't pass ... implying a need for more patches in the same area.

Fixed in http://hg.python.org/jython/rev/8b200f9ff1ea . And the next changeset updates test_datetime.py as I proposed, making the skips visible.

Thanks for this and related patches.
