Antoine Pitrou ea99c5c949 Issue #9410: Various optimizations to the pickle module, leading to
speedups up to 4x (depending on the benchmark).  Mostly ported from
Unladen Swallow; initial patch by Alexandre Vassalotti.

Benjamin Peterson ee8712cda4 #2621 rename test.test_support to test.support 2008-05-20 21:35:26 +00:00
Guido van Rossum f416981691 - A new pickle protocol (protocol 3) is added with explicit support
for bytes.  This is the default protocol.  It intentionally cannot
  be unpickled by Python 2.x.

- When a pickle	written	by Python 2.x contains an (8-bit) str
  instance, this is now decoded to a (Unicode) str instance.  The
  encoding used to do this defaults to ASCII, but can be overridden
  via two new keyword arguments to the Unpickler class.  Previously
  this would create bytes instances, which is usually wrong: str
  instances are often used to pickle attribute names etc., and text is
  more common than binary data anyway.

  #1330538: Improve comparison of xmlrpclib.DateTime and datetime instances.
  Remove automatic handling of datetime.date and datetime.time.
  This breaks backward compatibility, but python-dev discussion was strongly
  against this automatic conversion; see the bug for a link.

Guido van Rossum 98297ee781 Merging the py3k-pep3137 branch back into the py3k branch.
No detailed change log; just check out the change log for the py3k-pep3137
branch.  The most obvious changes:

  - str8 renamed to bytes (PyString at the C level);
  - bytes renamed to buffer (PyBytes at the C level);
  - PyString and PyUnicode are no longer compatible.

I.e. we now have an immutable bytes type and a mutable bytes type.

The behavior of PyString was modified quite a bit, to make it more
bytes-like.  Some changes are still on the to-do list.

Guido van Rossum cfe5f20fe8 Got test_pickletools and test_pickle working.
(Alas, test_cpickle is still broken.)

Walter Dörwald 21d3a32b99 Combine the functionality of test_support.run_unittest()
and test_support.run_classtests() into run_unittest()
and use it wherever possible.

Also don't use "from test.test_support import ...", but
"from test import test_support" in a few spots.

From SF patch #662807.

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.

Tim Peters e14295cf5f pickle.py has a few doctest'ed internal functions, so run their tests. 2003-01-30 21:27:37 +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.

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.

Guido van Rossum 9d32bb1708 Rename 'bin' arg to 'proto'. Keep the default at 0 lest the tests
change in meaning.

Jeremy Hylton 5e0f4e73a9 Remove inst_persistent_id() WANNI (we ain't never needed it).
Add some simple tests of the persistence hooks.

Barry Warsaw 408b6d34de Complete the absolute import patch for the test suite. All relative
imports of test modules now import from the test package.  Other
related oddities are also fixed (like DeprecationWarning filters that
weren't specifying the full import part, etc.).  Also did a general
code cleanup to remove all "from test.test_support import *"'s.  Other
from...import *'s weren't changed.
2002-07-30 23:27:12 +00:00
Barry Warsaw 04f357cffe Get rid of relative imports in all unittests. Now anything that
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".

This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).

Now Tim and Jack can have at it. :)

Jeremy Hylton be467e5c69 Fix Bug #114293:
Strings are unpickled by calling eval on the string's repr. This
    change makes pickle work like cPickle; it checks if the pickled
    string is safe to eval and raises ValueError if it is not.

test suite modifications:
    Verify that pickle catches a variety of insecure string pickles
    Make test_pickle and test_cpickle use exactly the same test suite
    Add test for pickling recursive object
