* An instance of class PicklingError was used here simply as an example ofTim Peters2005-02-151-21/+26
| | | | | | | _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.

| | | | | | | | | | 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.

* dis(): Not all opcodes are printable anymore, so print the reprTim Peters2003-01-281-126/+150
| | | | | | | | | | 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.
* Fix one disassembly output now that empty tuples are no longerGuido van Rossum2003-01-281-12/+11

* Now that proto2 is defined, replaced XXX blocks with text about it.Tim Peters2003-01-281-175/+206
| | | | | Also moved the proto2 opcode descriptors into the sections they fit (like TUPLE{1,2,3} in the group of tuple-building opcodes; etc).

* Removed the new LONG2 opcode: it's extravagant. If LONG1 isn't enough,Tim Peters2003-01-281-51/+13
| | | | | | | | | | | | | | | | | | | 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.

this over the weekend, and it made faster & better progress than I expected -- it's already useful <wink>.
