Olivier Grisel 3cd7c6e6eb bpo-31993: Do not allocate large temporary buffers in pickle dump. (#4353)
The picklers do no longer allocate temporary memory when dumping large
bytes and str objects into a file object. Instead the data is
directly streamed into the underlying file object.

Previously the C implementation would buffer all content and issue a
single call to file.write() at the end of the dump. With protocol 4
this behavior has changed to issue one call to file.write() per frame.

The Python pickler with protocol 4 now dumps each frame content as a
memoryview to an IOBytes instance that is never reused and the
memoryview is no longer released after the call to write. This makes it
possible for the file object to delay access to the memoryview of
previous frames without forcing any additional memory copy as was
already possible with the C pickler.

Serhiy Storchaka 05dadcfb28 Issue #19858: pickletools.optimize() now aware of the MEMOIZE opcode, can

Antoine Pitrou d9dfaa9487 Issue #6137: The pickle module now translates module names when loading
or dumping pickles with a 2.x-compatible protocol, in order to make data
sharing and migration easier. This behaviour can be disabled using the
new `fix_imports` optional argument.

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.

Tim Peters 8ecfc8ef9d Moving pickletools.py from the sandbox into the std library. I started
this over the weekend, and it made faster & better progress than I
expected -- it's already useful <wink>.
