Guido van Rossum 26d95c3d07 More str/bytes fixes. 2007-08-27 23:18:54 +00:00
Guido van Rossum 39478e8528 Changes in anticipation of stricter str vs. bytes enforcement. 2007-08-27 17:23:59 +00:00
Guido van Rossum 99603b0c1e Getting rid of cPickle. Mmm, feels good! 2007-07-20 00:22:32 +00:00
Guido van Rossum f93254d299 Fix test_pickle, by reverting the string opcodes (S, T, U) to returning
strings, in Latin-1.  Bytes are once more pickled through bytes.__reduce__,
but now it returns "latin-1" as the second parameter.

Unfortunately this breaks datetime pickling.  I'll have to investigate
further; reverting Martin's changes doesn't seem to help.

Martin v. Löwis 10a60b3ec0 Change Py_BuildValue to generate Unicode objects for
's' and 'c' codes.
Change pickle to dump bytes objects using the 'S'
code, and to load the 'S' code as byte objects.
Change datetime and array to generate and expect
bytes objects in reduce/unreduce.

Guido van Rossum aa588c4699 Fix some problems introduced by the str8 repr change. 2007-06-15 03:35:38 +00:00
Walter Dörwald 42748a8d6d Rip out all codecs that can't work in a unicode/bytes world:
base64, uu, zlib, rot_13, hex, quopri, bz2, string_escape.

However codecs.escape_encode() and codecs.escape_decode()
still exist, as they are used for pickling str8 objects
(so those two functions can go, when the str8 type is removed).

  Remove the imageop module.  With imgfile already removed in Python 3.0 and
  rgbimg gone in Python 2.6 the unit tests themselves were made worthless.  Plus
  third-party libraries perform the same function much better.

    Last try for tweaking the max stack depth.  5000 was the original value,
    4000 didn't work either.  1000 does work on Windows.  If 2000 works,

Guido van Rossum cc2b016125 - PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;
and .keys(), .items(), .values() return dict views.

The dict views aren't fully functional yet; in particular, they can't
be compared to sets yet.  but they are useful as "iterator wells".

There are still 27 failing unit tests; I expect that many of these
have fairly trivial fixes, but there are so many, I could use help.

Jeremy Hylton e3a565eed0 Fix grammar in comment. 2003-06-29 16:59:59 +00:00
Guido van Rossum 443ada47c3 Remove unused _better_reduce (which will disappear soon) and
_reconstructor (whose import here is a mystery to me).
2003-02-18 22:49:10 +00:00
Guido van Rossum c53f009f94 Introducing __reduce_ex__, which is called with a protocol number argument
if it exists in preference over __reduce__.  Now Tim can go implement this
in cPickle.c.
2003-02-18 22:05:12 +00:00
Tim Peters 080c88b912 cPickle.c, load_build(): Taught cPickle how to pick apart
the optional proto 2 slot state.

pickle.py, load_build():  CAUTION:  Noted that cPickle's
load_build and pickle's load_build really don't do the same
things with the state, and didn't before this patch either.
cPickle never tries to do .update(), and has no backoff if
instance.__dict__ can't be retrieved.  There are no tests
that can tell the difference, and part of what cPickle's
load_build() did looked accidental to me, so I don't know
what the true intent is here.

pickletester.py, test_pickle.py:  Got rid of the hack for
exempting cPickle from running some of the proto 2 tests.

dictobject.c, PyDict_Next():  documented intended use.
2003-02-15 03:01:11 +00:00
Tim Peters 8587b3c073 Added a HIGHEST_PROTOCOL module attribute to pickle and cPickle. 2003-02-13 15:44:41 +00:00
Tim Peters 42f08ac1e3 Implemented batching for dicts in cPickle. This is after two failed
attempts to merge the C list-batch and dict-batch code -- they worked, but
it was a godawful mess to read.
2003-02-11 22:43:24 +00:00
Tim Peters 1092d64002 Implemented list batching in cPickle. 2003-02-11 21:06:20 +00:00
Guido van Rossum cf117b0b40 Rename 'proto' keyword arg to 'protocol' . Greg Ward's suggestion. 2003-02-09 17:19:41 +00:00
Guido van Rossum 5aac4e6312 Move _better_reduce from copy.py to copy_reg.py, and also use it in
pickle.py, where it makes save_newobj() unnecessary.  Tests pass.
2003-02-06 22:57:00 +00:00
Guido van Rossum 98b922c0ec Remove a debug print statement. 2003-02-06 19:30:38 +00:00
Jeremy Hylton cc1fccbc1c No need for a continuation line. 2003-02-06 16:23:01 +00:00
Jeremy Hylton 656d4519b5 Replace hasattr() + getattr() with single getattr() and default value. 2003-02-06 16:22:01 +00:00
Guido van Rossum d4b920c8bd Rename the extension registry variables to have leading underscores --
this clarifies that they are part of an internal API (albeit shared
between pickle.py, copy_reg.py and cPickle.c).

I'd like to do the same for copy_reg.dispatch_table, but worry that it
might be used by existing code.  This risk doesn't exist for the
extension registry.

Guido van Rossum 93fe564217 _slotnames(): this is a fairly expensive calculation. Cache the
outcome as __slotnames__ on the class.  (Like __slots__, it's not safe
to ask for this as an attribute -- you must look for it in the
specific class's __dict__.  But it must be set using attribute
notation, because __dict__ is a read-only proxy.)
2003-02-03 19:46:54 +00:00
Guido van Rossum 868ecc22ab _slotnames(): exclude __dict__ and __weakref__; these aren't real
slots even though they can be listed in __slots__.
2003-02-03 18:10:09 +00:00
Guido van Rossum 795ea89cb5 Support keyword argument 'bin', with a pending deprecation warning. 2003-02-03 16:59:48 +00:00
Tim Peters 1d63c9f151 cPickle support for TUPLE[123]. Incidentally plugged several undetected
overflow holes in Pdata_grow().
2003-02-02 20:29:39 +00:00
Tim Peters bf2674be0e long(string, base) now takes time linear in len(string) when base is a
power of 2.  Enabled the tail end of test_long() in pickletester.py
because it no longer takes forever when run from test_pickle.py.
2003-02-02 07:51:32 +00:00
Tim Peters ee1a53cbb1 cPickle.c: Full support for the new LONG1 and LONG4. Added comments.
Assorted code cleanups; e.g., sizeof(char) is 1 by definition, so there's
no need to do things like multiply by sizeof(char) in hairy malloc
arguments.  Fixed an undetected-overflow bug in readline_file().

longobject.c:  Fixed a really stupid bug in the new _PyLong_NumBits.

pickle.py:  Fixed stupid bug in save_long():  When proto is 2, it
wrote LONG1 or LONG4, but forgot to return then -- it went on to
append the proto 1 LONG opcode too.
Fixed equally stupid cancelling bugs in load_long1() and
load_long4():  they *returned* the unpickled long instead of pushing
it on the stack.  The return values were ignored.  Tests passed
before only because save_long() pickled the long twice.

Fixed bugs in encode_long().

Noted that decode_long() is quadratic-time despite our hopes,
because long(string, 16) is still quadratic-time in len(string).
It's hex() that's linear-time.  I don't know a way to make decode_long()
linear-time in Python, short of maybe transforming the 256's-complement
bytes into marshal's funky internal format, and letting marshal decode
that.  It would be more valuable to make long(string, 16) linear time.

pickletester.py:  Added a global "protocols" vector so tests can try
all the protocols in a sane way.  Changed test_ints() and test_unicode()
to do so.  Added a new test_long(), but the tail end of it is disabled
because it "takes forever" under pickle.py (but runs very quickly under
cPickle:  cPickle proto 2 for longs is linear-time).
