is outside the range we expect.

Skip Montanaro fc070d2731 add %f format to datetime - issue 1158 2008-03-15 16:04:45 +00:00
Eric Smith a9f7d62480 Backport of PEP 3101, Advanced String Formatting, from py3k.
Highlights:
 - Adding PyObject_Format.
 - Adding string.Format class.
 - Adding __format__ for str, unicode, int, long, float, datetime.
 - Adding builtin format.
 - Adding ''.format and u''.format.
 - str/unicode fixups for formatters.

The files in Objects/stringlib that implement PEP 3101 (stringdefs.h,
unicodedefs.h, formatter.h, string_format.h) are identical in trunk
and py3k.  Any changes from here on should be made to trunk, and
changes will propogate to py3k).

Christian Heimes 000a074c95 Modified PyImport_Import and PyImport_ImportModule to always use absolute imports by calling __import__ with an explicit level of 0
Added a new API function PyImport_ImportModuleNoBlock. It solves the problem with dead locks when mixing threads and imports

Christian Heimes e93237dfcc #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE and Py_REFCNT. Macros for b/w compatibility are available. 2007-12-19 02:37:44 +00:00
Martin v. Löwis 6819210b9e PEP 3123: Provide forward compatibility with Python 3.0, while keeping
backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
PyVarObject_HEAD_INIT.

Kristján Valur Jónsson 7a0da19087 Complete revamp of PCBuild8 directory. Use subdirectories for each project under the main pcbuild solution. Now make extensive use of property sheets to simplify project configuration. x64 build fully supported, and the process for building PGO version (Profiler Guided Optimization) simplified. All projects are now present, except _ssl, which needs to be reimplemented. Also, some of the projects that require external libraries need extra work to fully compile on x64. 2007-04-30 15:17:46 +00:00

Thomas Wouters 3cfea2dc98 Coverity-found bug: datetime_strptime() failed to check for NULL return from
PySequence_GetItem of the time.strptime() result. Not a high probability
bug, but not inconceivable either, considering people can provide their own
'time' module.
2006-04-14 21:23:42 +00:00
Neal Norwitz d5b0c9b87e Fix problem spotted by Coverity that occurs if tzinfo.tzname().replace()
returns a non-string when converting %Z.

Will backport.

Probably should be backported.

Jeremy Hylton af68c874a6 Add const to several API functions that take char *.
In C++, it's an error to pass a string literal to a char* function
without a const_cast().  Rather than require every C++ extension
module to put a cast around string literals, fix the API to state the
const-ness.

I focused on parts of the API where people usually pass literals:
PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type
slots, etc.  Predictably, there were a large set of functions that
needed to be fixed as a result of these changes.  The most pervasive
change was to make the keyword args list passed to
PyArg_ParseTupleAndKewords() to be a const char *kwlist[].

One cast was required as a result of the changes:  A type object
mallocs the memory for its tp_doc slot and later frees it.
PyTypeObject says that tp_doc is const char *; but if the type was
created by type_new(), we know it is safe to cast to char *.

Armin Rigo f4afb21526 similar to SF bug 847019: a quick check in the time() constructor, which
accepts strings only for unpickling reasons.  This check prevents the honest
mistake of passing a string like '2:59.0' to time() and getting an insane
object.
2005-11-07 07:15:48 +00:00
Skip Montanaro 0af3ade6aa Add strptime() constructor to datetime class. Thanks to Josh Spoerri for
the changes.

Tim Peters 528ca53b74 SF bug #1028306: date-datetime comparison
Treat comparing a date to a datetime like a mixed-type comparison.

Tim Peters 9ddf40b4e1 SF patch 876130: add C API to datetime module, from Anthony Tuininga.
The LaTeX is untested (well, so is the new API, for that matter).
Note that I also changed NULL to get spelled consistently in concrete.tex.
If that was a wrong thing to do, Fred should yell at me.

Tim Peters 1b6f7a9057 Bug 975996: Add _PyTime_DoubleToTimet to C API
New include file timefuncs.h exports private API function
_PyTime_DoubleToTimet() from timemodule.c.  timemodule should export
some other functions too (look for painful bits in datetimemodule.c).

Added insane-argument checking to datetime's assorted fromtimestamp()
and utcfromtimestamp() methods.  Added insane-argument tests of these
to test_datetime, and insane-argument tests for ctime(), localtime()
and gmtime() to test_time.

Tim Peters 604c013ef2 SF 952807: Unpickling pickled instances of subclasses of datetime.date,
datetime.datetime and datetime.time could yield insane objects.  Thanks
to Jiwon Seo for the fix.

Bugfix candidate.  I'll backport it to 2.3.

Tim Peters 3f60629242 SF bug 847019 datetime.datetime initialization needs more strict checking
It's possible to create insane datetime objects by using the constructor
"backdoor" inserted for fast unpickling.  Doing extensive range checking
would eliminate the backdoor's purpose (speed), but at least a little
checking can stop honest mistakes.

Bugfix candidate.

Brett Cannon d1080a3418 Have strftime() check its time tuple argument to make sure the tuple's values
are within proper boundaries as specified in the docs.

This can break possible code (datetime module needed changing, for instance)
that uses 0 for values that need to be greater 1 or greater (month, day, and
day of year).

Fixes bug #897625.

Raymond Hettinger 8ae4689657 Simplify and speedup uses of Py_BuildValue():
* Py_BuildValue("(OOO)",a,b,c)  -->  PyTuple_Pack(3,a,b,c)
* Py_BuildValue("()",a)         -->  PyTuple_New(0)
* Py_BuildValue("O", a)         -->  Py_INCREF(a)

Raymond Hettinger f69d9f6818 SF bug #761337: datetime.strftime fails on trivial format string
The interning of short strings violates the refcnt==1 assumption for
_PyString_Resize().

A simple fix is to boost the initial value of "totalnew" by 1.
Combined with an NULL argument to PyString_FromStringAndSize(),
this assures that resulting format string is not interned.
This will remain true even if the implementation of
PyString_FromStringAndSize() changes because only the uninitialized
strings that can be interned are those of zero length.

Added a test case.

Tim Peters 03eaf8b1ae Added more words about the abuse of the tp_alloc nitems argument
perpetrated by the time and datetime classes.
2003-05-18 02:24:46 +00:00
Tim Peters b0c854d6a7 datetime.timedelta is now subclassable in Python. The new test shows
one good use:  a subclass adding a method to express the duration as
a number of hours (or minutes, or whatever else you want to add).  The
native breakdown into days+seconds+us is often clumsy.  Incidentally
moved a large chunk of object-initialization code closer to the top of
the file, to avoid worse forward-reference trickery.
2003-05-17 15:57:00 +00:00
Tim Peters a98924a063 datetime.datetime and datetime.time can now be subclassed in Python. Brr. 2003-05-17 05:55:19 +00:00
Tim Peters 4c53013030 Turns out there wasn't a need to define tp_free for any of the types here. 2003-05-16 22:44:06 +00:00

Guido van Rossum 8b7a9a38c6 The date class is now properly subclassable. (SF bug #720908)
(This is only the tip of the iceberg; the time and datetime classes
need the same treatment.)
2003-04-14 22:01:58 +00:00
Tim Peters aa7d849c7a timedelta comparison and datetime addition: as the Python implementation
of datetime does, accept instances of subclasses too.
2003-02-08 03:28:59 +00:00
Tim Peters 07534a607b Comparison for timedelta, time, date and datetime objects: __eq__ and
__ne__ no longer complain if they don't know how to compare to the other
thing.  If no meaningful way to compare is known, saying "not equal" is
sensible.  This allows things like

    if adatetime in some_sequence:
and
    somedict[adatetime] = whatever

to work as expected even if some_sequence contains non-datetime objects,
or somedict non-datetime keys, because they only call __eq__.

It still complains (raises TypeError) for mixed-type comparisons in
contexts that require a total ordering, such as list.sort(), use as a
key in a BTree-based data structure, and cmp().

Neal Norwitz ce3d34dde7 Whitespace normalization 2003-02-04 20:45:17 +00:00
Tim Peters 70533e28ad New functions alloc_{time,datetime}. Got rid of all setstate-like
functions.  Reworked {time,datetime}_new() to do what their corresponding
setstates used to do in their state-tuple-input paths, but directly,
without constructing an object with throwaway state first.  Tightened
the "is this a state tuple input?" paths to check the presumed state
string-length too, and to raise an exception if the optional second state
element isn't a tzinfo instance (IOW, check these paths for type errors
as carefully as the normal paths).
2003-02-01 04:40:04 +00:00
Tim Peters b57f8f02ba There's no good reason for datetime objects to expose __getstate__()
anymore either, so don't.  This also allows to get rid of obscure code
making __getnewargs__ identical to __getstate__ (hmm ... hope there
wasn't more to this than I realize!).
2003-02-01 02:54:15 +00:00
Tim Peters 1f1b2d2e68 Removed all uses of the out-of-favor __safe_for_unpickling__ magic
attr, and copy_reg.safe_constructors.
2003-02-01 02:16:37 +00:00
Tim Peters 371935fc06 All over: changed comments to reflect pickling is straightforward now,
not the maze it was.
2003-02-01 01:52:50 +00:00
Tim Peters 8a60c2238b delta_setstate(): This waS no longer referenced, so nukeit.
delta_reduce():  Simplified.
2003-02-01 01:47:29 +00:00
Tim Peters 506be287aa The various datetime object __setstate__() methods are no longer public
(pickling no longer needs them, and immutable objects shouldn't have
visible __setstate__() methods regardless).  Rearranged the code to
put the internal setstate functions in the constructor sections.
Repaired the timedelta reduce() method, which was still producing
stuff that required a public timedelta.__setstate__() when unpickling.
2003-01-31 22:27:17 +00:00
Tim Peters abc7cd27ff Backward branches are disgusting, at least when a forward branch
is just as easy.
2003-01-31 01:37:35 +00:00
Guido van Rossum 177e41a117 Change the approach to pickling to use __reduce__ everywhere. Most
classes have a __reduce__ that returns (self.__class__,
self.__getstate__()).  tzinfo.__reduce__() is a bit smarter, calling
__getinitargs__ and __getstate__ if they exist, and falling back to
__dict__ if it exists and isn't empty.
