Alexandre Vassalotti ea0b22a167 Patch by Quentin Gallet-Gilles: Renaming leftovers for 2.6.
This fixes the omissions of configparser, copyreg, queue and
socketserver renaming.

Raymond Hettinger da614dcc4f Complete an open todo on pickletools -- add a pickle optimizer. 2008-02-10 20:35:16 +00:00
Tim Peters 90718a4eb5 An instance of class PicklingError was used here simply as an example of
_some_ user-defined class instance.  That it was also an exception isn't
interesting, but does interfere with Michael Hudson's new-style exception
patch.  This just changes the doctest example, to use an instance of a
non-exception class.

Tim Peters 90cf212cef Essentially SF patch 1061679: add missing __all__ to pickletools.py.
Harmless.

Tim Peters 62235e701e dis(): Added an optional memo argument, so that multiple pickles in a
file can be dumped without (bogus) complaint if the the pickles were
created using a single pickle memo.

Tim Peters 4b23f2b44b It's Official: for LONG1/LONG4, a "byte count" of 0 is taken as a
shortcut meaning 0L.  This allows LONG1 to encode 0L in two bytes
total.

Tim Peters 2b93c4c708 Updated the INST/OBJ docs, to say they really are (almost) identical
in 2.3.

Tim Peters 43277d64eb dis(): Simplified stack emulation a bit. 2003-01-30 15:02:12 +00:00
Tim Peters c1c2b3e0e2 dis(): This had a problem with proto 0 pickles, in that POP sometimes
popped a MARK, but without stack emulation the disassembler couldn't
know that, and subsequent indentation got hosed.

Now the disassembler does do enough stack emulation to catch this.  While
I was at it, also added lots of sanity checks for other stack operations,
and correct use of the memo.  This goes (I think) a long way toward being
a "pickle verifier" now too.

between cPickle and pickle.py regarding __safe_for_unpickling__ before
Python 2.3.

Tim Peters c0c12b5707 pickle: Comment repair.
pickletools:  Import decode_long from pickle instead of duplicating it.

Tim Peters 55762f5f80 Use raw-mode docstring whenever there's an escape code in an example --
they're easier to read this way.

Guido van Rossum 03e35327f2 _dis_test should be a raw string now that it contains \x escapes. 2003-01-28 15:37:13 +00:00
Tim Peters d0f7c86a20 dis(): Not all opcodes are printable anymore, so print the repr
of the opcode character instead (but stripping the quotes).

Added a proto 2 test section for the canonical recursive-tuple case.
Note that since pickle's save_tuple() takes different paths depending on
tuple length now, beefier tests are really needed (but not in pickletools);
the "short tuple" case tried here was actually broken yesterday, and it's
subtle stuff so needs to be tested.

Guido van Rossum 570283584a Fix one disassembly output now that empty tuples are no longer
memoized in text mode.  Fixed some variable names in the disassembler
doctest.

Tim Peters fdc03462b3 Now that proto2 is defined, replaced XXX blocks with text about it.
Also moved the proto2 opcode descriptors into the sections they fit (like
TUPLE{1,2,3} in the group of tuple-building opcodes; etc).

Tim Peters fdb8cfab08 Removed the new LONG2 opcode: it's extravagant. If LONG1 isn't enough,
then the embedded argument consumes at least 256 bytes.  The difference
between a 3-byte prefix (LONG2 + 2 bytes) and a 5-byte prefix (LONG4 +
4 bytes) is at worst less than 1%.  Note that binary strings and binary
Unicode strings also have only "size is 1 byte, or size is 4 bytes?"
flavors, and I expect for the same reason.  The only place a 2-byte
thingie was used was in BININT2, where the 2 bytes make up the *entire*
embedded argument (and now EXT2 also does this); that's a large savings
over 4 bytes, because the total opcode+argument size is so small in
the BININT2/EXT2 case.

Removed the TAKEN_FROM_ARGUMENT "number of bytes" code, and bifurcated it
into TAKEN_FROM_ARGUMENT1 and TAKEN_FROM_ARGUMENT4.  Now there's enough
info in ArgumentDescriptor objects to deduce the # of bytes consumed by
each opcode.

Rearranged the order in which proto2 opcodes are listed in pickle.py.

Guido van Rossum f29d3d6011 Begin the change from 'binary vs. text mode' to 'protocol 0, 1, 2'.
The protocol now defaults to 1.  Protocol 2 is still unimplemented.

Tim Peters 1996e23054 Repaired comment. 2003-01-27 19:38:34 +00:00
Tim Peters d916cf4ec7 stringnl_noescape_pair(): changed the reader to separate the two
component strings by a blank instead of a period.  Guido pointed
out that the component strings (at least the first one) can be
dotted already.  find_class() is overridable too, so only God knows
all the possibilities that make sense to someone.

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>.
