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

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.

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

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

c9d7c4a656 Added XXX about save()'s special-casing of tuples -- I don't get it. 2003-01-28 00:43:26 +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.

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>.

f8de21c51b Merge with PyXML 1.3: 
Add support for the DOM Level 3 (draft) DOMImplementationSource interface
to the xml.dom and xml.dom.minidom modules.  Note API issue: the draft spec
says to return null when there is no suitable implementation, while the
Python getDOMImplementation() function raises ImportError (minor).
