- Add tests for the module-level load() and dump() functions.
- Add tests for cPickle's internal data structures, stressing workloads
with many gets/puts.
- Add tests for the Pickler and Unpickler classes, in particular the
memo attribute.
- test_xpickle is extended to test backwards compatibility with Python
2.4, 2.5 and 2.6 by round-tripping pickled objects through a worker
process. This is guarded with a regrtest -u xpickle resource.
behaviours. I left the original test commented out (note
that that test came from #2702, which seems to have a
problem in FreeBSD and Windows, but not in Linux).
I included a new test, to watch over the now-broken
behaviour, I took it from #3179.
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.
test_nonrecursive_deep(): Reduced nesting depth to 60.
Not a bugfix candidate. 2.3 increased the number of stack frames
needed to pickle a list (in order to get implement the "list
batching" unpickling memory optimization new in 2.3).
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. :)
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
"""
In the course of debugging this I also saw that cPickle is
inconsistent with pickle - if you attempt a pickle.load or pickle.dump
on a closed file, you get a ValueError, whereas the corresponding
cPickle operations give an IOError. Since cPickle is advertised as
being compatible with pickle, I changed these exceptions to match.
