  Issue 7128: Removed reference to the non-existent copyreg module.

  The reference to copyreg was a unnoticed leftover from the compatibility
  support for the grand renaming of the standard library in Python 3. The
  compatibility support was reverted in r63493, but not completely as this
  patch shows.

  Based on a patch by Amaury Forgeot d'Arc.

2003-02-18 22:41:24 +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 71fcda5ba7 cPickle produces NEWOBJ appropriately now. It still doesn't know

Tim Peters c0c9370985 We didn't have any tests making pickles with one of {pickle, cPickle},
and loading them via the other, except for the special cases of this
Guido added to test_datetime.py for datetime module objects.  The new
test_xpickle.py tries all of pickletester's AbstractPickleTests in
both x-module ways.
2003-02-13 19:30:57 +00:00
Tim Peters e9ef203ea6 Added a simple NEWOBJ test. This is in the pickle-only part of the
test for now (cPickle can't yet produce NEWOBJ).
2003-02-13 18:42:00 +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
Tim Peters 8d2613adbe Added tests to ensure that list and dict "chunking" are actually
getting done.  Since this isn't yet implemented in cPickle, the
new tests are in TempAbstractPickleTests (which cPickle doesn't
run).
2003-02-11 16:40:16 +00:00
Tim Peters 3e667d5452 cPickle: exempt two_tuple from GC -- it's a speed hack, and doesn't
guarantee to keep valid pointers in its slots.

tests:  Moved ExtensionSaver from test_copy_reg into pickletester, and
use it both places.  Once extension codes get assigned, it won't be
safe to overwrite them willy nilly in test suites, and ExtensionSaver
does a thorough job of undoing any possible damage.

Beefed up the EXT[124] tests a bit, to check the smallest and largest
codes in each opcode's range too.
2003-02-04 21:47:44 +00:00
Tim Peters 731098b3ff cPickle now generates proto 2 EXT[124] when appropriate.
Moved such EXT tests as currently exist from TempAbstractPickleTests to
AbstractPickleTests, so that test_cpickle runs them too.
2003-02-04 20:56:09 +00:00
Tim Peters 894453a28d test_newobj_tuple(), test_newobj_list(): These tests should work under
all protocols, so tried them under all.
2003-02-03 22:32:18 +00:00
Tim Peters 5013bd9438 test_newobj_generic(): Use the global protocols vector instead of a
hardcoded list.
2003-02-03 22:28:41 +00:00
Tim Peters 22e71711b3 Added a bit to the EXT[124] tests, and refactored them to squash code
duplication.  Note that these still don't get run under cPickle.
2003-02-03 22:27:38 +00:00
Tim Peters 61bf257633 Do a better job of testing that opcodes aren't generated under protocols
earlier than the ones in which they were introduced.
2003-02-03 21:31:22 +00:00
Tim Peters 31f119ebdb Proper testing of proto 2 in part requires checking that the new opcodes
are actually getting generated.  Add helpered method
ensure_opcode_in_pickle to do a correct job checking for that.  Changed
test_long1(), test_long4(), and test_short_tuples() to use it.
2003-02-03 16:20:13 +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 3c67d795ef Implemented proto 2 NEWTRUE and NEWFALSE in cPickle. 2003-02-02 17:59:11 +00:00
Tim Peters 70b02d79f9 Beefed up the tests by putting in more "for proto in protocols:" outer
loops.  Renamed DATA and BINDATA to DATA0 and DATA1.  Included
disassemblies, but noted why we can't test them.  Added XXX comment to
cPickle about a mysterious comment, where pickle and cPickle diverge
in how they number PUT indices.
2003-02-02 17:26:40 +00:00
Tim Peters 4190fb8429 Add cPickle support for PROTO. Duplicated PROTO/LONG1/LONG4 code in
the hitherto unknown (to me) noload() cPickle function, which is (a)
something we don't test at all, and (b) pickle.py doesn't have.
2003-02-02 16:09:05 +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).
2003-02-02 02:57:53 +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
Guido van Rossum 5d9113d8be Implement appropriate __getnewargs__ for all immutable subclassable builtin
types.  The special handling for these can now be removed from save_newobj().
Add some testing for this.

Also add support for setting the 'fast' flag on the Python Pickler class,
which suppresses use of the memo.
2003-01-29 17:58:45 +00:00
Guido van Rossum 0322d0ff13 Test all three EXT opcodes, and move these tests into
TempAbstractPickleTests, because they don't work with cPickle yet.
2003-01-29 06:12:46 +00:00
Tim Peters 47a6b13988 Temporary hacks to arrange that the pickle tests relying on protocol 2
only get run by test_pickle.py now (& not by test_cpickle.py).  This
should be undone when protocol 2 is implemented in cPickle too.
test_cpickle should pass again.
2003-01-28 22:34:11 +00:00
Guido van Rossum c8d6ef5cd6 Add a test for a list subclass with a __dict__ as well as slots. 2003-01-28 22:02:31 +00:00
Guido van Rossum 3d8c01b31c The default __reduce__ on the base object type obscured any
possibility of calling save_reduce().  Add a special hack for this.
The tests for this are much simpler now (no __getstate__ or
__getnewargs__ needed).
2003-01-28 19:48:18 +00:00
Guido van Rossum 533dbcf250 Some experimental support for generating NEWOBJ with proto=2, and
fixed a bug in load_newobj().
2003-01-28 17:55:05 +00:00
Guido van Rossum 7d97d31a1b OK, this is really the last one tonight!
NEWFALSE and NEWTRUE.
2003-01-28 04:25:27 +00:00
Guido van Rossum 025bc2fe6c Shouldn't test short tuples with all items equal -- one potential bug
would be that the tuple is reversed on unpickling, and we should catch
that. :-)

Goodnight -- that's it for toniht!
2003-01-28 04:20:02 +00:00
Guido van Rossum 44f0ea5f73 More protocol 2: TUPLE1, TUPLE2, TUPLE3.
Also moved the special case for empty tuples from save() to save_tuple().
