| * | Slight code rearrangement to avoid testing getstate twice. | Guido van Rossum | 2003-01-30 | 1 | -22/+23 | |
| | | ||||||
| * | In save_newobj(), if an object's __getnewargs__ and __getstate__ are | Guido van Rossum | 2003-01-30 | 1 | -0/+23 | |
| | | | | | | | | | | the same function, don't save the state or write a BUILD opcode. This is so that a type (e.g. datetime :-) can support protocol 2 using __getnewargs__ while also supporting protocol 0 and 1 using __getstate__. (Without this, the state would be pickled twice with protocol 2, unless __getstate__ is defined to return None, which breaks protocol 0 and 1.) | |||||
| * | Use %c rather than chr() to turn some ints into chars. | Guido van Rossum | 2003-01-29 | 1 | -2/+2 | |
| | | ||||||
| * | Implement appropriate __getnewargs__ for all immutable subclassable builtin | Guido van Rossum | 2003-01-29 | 1 | -8/+4 | |
| | | | | | | | | | 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. | |||||
| * | Declare Protocol 2 as implemented. | Guido van Rossum | 2003-01-29 | 1 | -1/+1 | |
| | | ||||||
| * | Support for extension codes. (By accident I checked in the tests first.) | Guido van Rossum | 2003-01-29 | 1 | -8/+63 | |
| | | ||||||
| * | pickle: Comment repair. | Tim Peters | 2003-01-29 | 1 | -4/+9 | |
| | | | | | pickletools: Import decode_long from pickle instead of duplicating it. | |||||
| * | Add a comment about how some built-in types should grow a | Guido van Rossum | 2003-01-28 | 1 | -1/+3 | |
| | | | | | __getnewargs__ method. | |||||
| * | Get rid of __safe_for_unpickling__ and safe_constructors. | Guido van Rossum | 2003-01-28 | 1 | -28/+12 | |
| | | | | | Also tidied up a few lines, got rid of apply(), added a comment. | |||||
| * | Instead of bad hacks trying to worm around the inherited | Guido van Rossum | 2003-01-28 | 1 | -37/+79 | |
| | | | | | | | | | | | | | | object.__reduce__, do a getattr() on the class so we can explicitly test for it. The reduce()-calling code becomes a bit more regular as a result. Also add support slots: if an object has slots, the default state is (dict, slots) where dict is the __dict__ or None, and slots is a dict mapping slot names to slot values. We do a best-effort approach to find slot names, assuming the __slots__ fields of classes aren't modified after class definition time to misrepresent the actual list of slots defined by a class. | |||||
| * | The default __reduce__ on the base object type obscured any | Guido van Rossum | 2003-01-28 | 1 | -7/+39 | |
| | | | | | | | possibility of calling save_reduce(). Add a special hack for this. The tests for this are much simpler now (no __getstate__ or __getnewargs__ needed). | |||||
| * | Move the NEWOBJ-generating code to a separate function, and invoke it | Guido van Rossum | 2003-01-28 | 1 | -24/+28 | |
| | | | | | after checking for __reduce__. | |||||
| * | Some experimental support for generating NEWOBJ with proto=2, and | Guido van Rossum | 2003-01-28 | 1 | -2/+31 | |
| | | | | | fixed a bug in load_newobj(). | |||||
| * | save_empty_tuple(): Comment on why we can't get rid of this. | Tim Peters | 2003-01-28 | 1 | -0/+3 | |
| | | ||||||
| * | save_dict(): Added a comment about the control flow NealN missed. | Tim Peters | 2003-01-28 | 1 | -1/+2 | |
| | | ||||||
| * | _is_string_secure(): This method is no longer used; removed it. (It | Tim Peters | 2003-01-28 | 1 | -37/+0 | |
| | | | | | was used before string-escape codecs were added to the core.) | |||||
| * | Made save() fit on a page, while adding comments. (I moved some type | Guido van Rossum | 2003-01-28 | 1 | -60/+69 | |
| | | | | | | | checks to save_reduce(), which can also be called from a subclass.) Also tweaked some more comments. | |||||
| * | Got rid of the _quotes global. Used only once, and is trivial. | Tim Peters | 2003-01-28 | 1 | -3/+1 | |
| | | ||||||
| * | Add a few comments. Change the way the protocol is checked (it must | Guido van Rossum | 2003-01-28 | 1 | -2/+8 | |
| | | | | | | | | be one of 0, 1 or 2). I should note that the previous checkin also added NEWOBJ support to the unpickler -- but there's nothing yet that generates this. | |||||
| * | Rename all variables 'object' to 'obj' to avoid conflicts with the | Guido van Rossum | 2003-01-28 | 1 | -112/+113 | |
| | | | | | | type 'object'. Also minor docstring tweakage, and rearranged a few lines in save(). | |||||
| * | Don't memoize the empty tuple in protocol 0. | Guido van Rossum | 2003-01-28 | 1 | -1/+2 | |
| | | ||||||
| * | save_tuple(): So long as the charter is rewriting for clarity, the snaky | Tim Peters | 2003-01-28 | 1 | -21/+20 | |
| | | | | | control flow had to be simplified. | |||||
| * | save_tuple(): I believe the new code for TUPLE{1,2,3} in proto 2 was | Tim Peters | 2003-01-28 | 1 | -2/+5 | |
| | | | | | | incorrect for recursive tuples. Tried to repair; seems to work OK, but there are no checked-in tests for this yet. | |||||
| * | OK, this is really the last one tonight! | Guido van Rossum | 2003-01-28 | 1 | -1/+12 | |
| | | | | | NEWFALSE and NEWTRUE. | |||||
| * | More protocol 2: TUPLE1, TUPLE2, TUPLE3. | Guido van Rossum | 2003-01-28 | 1 | -11/+35 | |
| | | | | | Also moved the special case for empty tuples from save() to save_tuple(). | |||||
| * | save_inst(): Rewrote to have only one branch on self.bin. Also got rid | Tim Peters | 2003-01-28 | 1 | -16/+9 | |
| | | | | | | of my recent XXX comment, taking a (what appears to be vanishingly small) chance and calling self.memoize() instead. | |||||
| * | First baby steps towards implementing protocol 2: PROTO, LONG1 and LONG4. | Guido van Rossum | 2003-01-28 | 1 | -1/+88 | |
| | | ||||||
| * | Fixed odd whitespace after "if", which I believe I introduced long ago. | Tim Peters | 2003-01-28 | 1 | -1/+1 | |
| | | ||||||
| * | save_int(): Fixed two new off-by-1 glitches. | Tim Peters | 2003-01-28 | 1 | -2/+2 | |
| | | ||||||
| * | Add a comment explaining that struct.pack() beats marshal.dumps(), but | Guido van Rossum | 2003-01-28 | 1 | -0/+3 | |
| | | | | | | marshal.loads() beats struct.unpack()! Possibly because the latter creates a one-tuple. :-( | |||||
| * | Got rid of mdumps; I timed it, and struct.pack("<i", x) is more than | Guido van Rossum | 2003-01-28 | 1 | -30/+26 | |
| | | | | | | 40% faster than marshal.dumps(x)[1:]! (That's not counting the module attribute lookups, which can be avoided in either case.) | |||||
| * | save_tuple(): Minor rewriting, and added a comment about the subtlety | Tim Peters | 2003-01-28 | 1 | -8/+13 | |
| | | | | | created by recursive tuples. | |||||
| * | load_appends(): replaced .append() loop with an .extend(). | Tim Peters | 2003-01-28 | 1 | -3/+1 | |
| | | ||||||
| * | Comments. | Tim Peters | 2003-01-28 | 1 | -1/+9 | |
| | | ||||||
| * | save_dict(): Untangled most of the bin-vs-not-bin logic. Also used | Tim Peters | 2003-01-28 | 1 | -15/+14 | |
| | | | | | | iteritems() instead of materializing a (possibly giant) list of the items. | |||||
| * | save_list(): Rewrote, to untangle the proto 0 from the proto 1 cases. | Tim Peters | 2003-01-28 | 1 | -15/+17 | |
| | | | | | The code is much easier to follow now, and I bet it's faster too. | |||||
| * | save_list(): removed unused local "d". | Tim Peters | 2003-01-28 | 1 | -2/+0 | |
| | | ||||||
| * | save_list(): removed unused local "memo". | Tim Peters | 2003-01-28 | 1 | -1/+0 | |
| | | ||||||
| * | save_pers(): Switched the order of cases, to get rid of a "not", and to | Tim Peters | 2003-01-28 | 1 | -3/+3 | |
| | | | | | | make the bin-vs-not-bin order consistent with what other routines try to do (they almost all handle the bin case first). | |||||
| * | Several routines appeared to inline the guts of memoize(), possibly for | Tim Peters | 2003-01-28 | 1 | -12/+9 | |
| | | | | | | | some notion of low-level efficiency. Undid that, but left one routine alone: save_inst() claims it has a reason for not using memoize(). I don't understand that comment, so added an XXX comment there. | |||||
| * | save(): Fiddled the control flow to put the normal case where it | Tim Peters | 2003-01-28 | 1 | -44/+47 | |
| | | | | | | belongs. This is a much smaller change than it may appear: the bulk of the function merely got unindented by one level. | |||||
| * | Added XXX about save()'s special-casing of tuples -- I don't get it. | Tim Peters | 2003-01-28 | 1 | -0/+1 | |
| | | ||||||
| * | save_bool(): simplified. | Tim Peters | 2003-01-28 | 1 | -4/+1 | |
| | | ||||||
| * | Repaired grammar in new comment. | Tim Peters | 2003-01-28 | 1 | -1/+1 | |
| | | ||||||
| * | clear_memo(): Repaired grammar in docstring. | Tim Peters | 2003-01-28 | 1 | -3/+3 | |
| | | ||||||
| * | Added one-line comments to the proto 2 opcodes. | Tim Peters | 2003-01-28 | 1 | -14/+14 | |
| | | ||||||
| * | Removed the new LONG2 opcode: it's extravagant. If LONG1 isn't enough, | Tim Peters | 2003-01-28 | 1 | -7/+6 | |
| | | | | | | | | | | | | | | | | | | | | 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. | |||||
| * | Begin the change from 'binary vs. text mode' to 'protocol 0, 1, 2'. | Guido van Rossum | 2003-01-27 | 1 | -11/+24 | |
| | | | | | The protocol now defaults to 1. Protocol 2 is still unimplemented. | |||||
| * | Begin documenting protocol 2. | Guido van Rossum | 2003-01-27 | 1 | -0/+16 | |
| | | ||||||
| * | Added some comments. | Tim Peters | 2003-01-27 | 1 | -0/+2 | |
