d6c9e63af9 First baby steps towards implementing protocol 2: PROTO, LONG1 and LONG4. 2003-01-28 03:49:52 +00:00
Tim Peters
d95c2df3a9 Fixed odd whitespace after "if", which I believe I introduced long ago. 2003-01-28 03:41:54 +00:00

8fda7bc48d save_int(): Fixed two new off-by-1 glitches. 2003-01-28 03:40:52 +00:00

e0b904232f Add a comment explaining that struct.pack() beats marshal.dumps(), but 
marshal.loads() beats struct.unpack()!  Possibly because the latter
creates a one-tuple. :-(

5c938d00a1 Got rid of mdumps; I timed it, and struct.pack("<i", x) is more than 
40% faster than marshal.dumps(x)[1:]!  (That's not counting the
module attribute lookups, which can be avoided in either case.)

f558da0f90 save_tuple(): Minor rewriting, and added a comment about the subtlety 
created by recursive tuples.

209ad95b00 load_appends(): replaced .append() loop with an .extend(). 2003-01-28 01:44:45 +00:00

064567e41a save_dict(): Untangled most of the bin-vs-not-bin logic. Also used 
iteritems() instead of materializing a (possibly giant) list of the
items.
 2003-01-28 01:34:43 +00:00
Tim Peters
21c18f0bf5 save_list(): Rewrote, to untangle the proto 0 from the proto 1 cases. 
The code is much easier to follow now, and I bet it's faster too.
 2003-01-28 01:15:46 +00:00

22dc6f4f7a save_list(): removed unused local "d". 2003-01-28 01:07:48 +00:00
Tim Peters
58d7846e68 save_list(): removed unused local "memo". 2003-01-28 01:07:10 +00:00
Tim Peters
bd1cdb9227 save_pers(): Switched the order of cases, to get rid of a "not", and to 
make the bin-vs-not-bin order consistent with what other routines try to
do (they almost all handle the bin case first).
 2003-01-28 01:03:10 +00:00
Tim Peters
518df0dae4 Several routines appeared to inline the guts of memoize(), possibly for 
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.

b32a8317d7 save(): Fiddled the control flow to put the normal case where it 
belongs.  This is a much smaller change than it may appear:  the bulk
of the function merely got unindented by one level.
 2003-01-28 00:48:09 +00:00
Tim Peters
c9d7c4a656 Added XXX about save()'s special-casing of tuples -- I don't get it. 2003-01-28 00:43:26 +00:00

22987e3cbd save_bool(): simplified. 2003-01-28 00:26:14 +00:00

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.

217e571a19 decode_long(): Simplified the "is it negative?" test. 2003-01-27 23:51:11 +00:00
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.

e46b73f5b3 memoize(): Reworded the docs to try to disentangle the Pickler's memo 
dict from the Unpickler's memo (which is a different beast!).

bbf63cd05c Using marshal functions to pack & unpack 1-byte ints is an obscure & 
expensive way to spell chr() and ord().

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.

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>.
