[I hope this belongs on python-dev, since it's about the design of
something. But if not, let me know and I'll post to c.l.py.]
I'm willing to file a bug report and patch on this, but I'd like to know
if it's by design or not.
In datetimemodule.c, the function wrap_strftime() insists that the
length of a format string be <= 127 chars, by forcing the length into a
char. This seems like a bug to me. wrap_strftime() calls time's
strftime(), which doesn't have this limitation because it uses size_t.
>>> import datetime
>>> datetime.datetime.now().strftime('x'*128)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
MemoryError
>>> import datetime
>>> datetime.datetime.now().strftime('x'*256)
in wrap_strftime
totalnew=1
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
SystemError: Objects/stringobject.c:4077: bad argument to internal function
>>> import time
>>> time.strftime('x'*128)
'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
But before I write this up, I'd like to know if anyone knows if this is
by design or not.
This is reproducible on Windows 2.4.3, and Linux 2.3.3 and 2.5c1.
Thanks.
Eric.
