_is_string_secure(): This method is no longer used; removed it. (It
...
was used before string-escape codecs were added to the core.)

Made save() fit on a page, while adding comments. (I moved some type
...
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.

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

_dis_test should be a raw string now that it contains \x escapes.

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.

Add a few comments. Change the way the protocol is checked (it must
...
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.
2003-01-28 15:19:53 +00:00

Rename all variables 'object' to 'obj' to avoid conflicts with the
...
type 'object'. Also minor docstring tweakage, and rearranged a few
lines in save().

Fix one disassembly output now that empty tuples are no longer

memoized in text mode. Fixed some variable names in the disassembler
doctest.

Don't memoize the empty tuple in protocol 0.

save_tuple(): So long as the charter is rewriting for clarity, the snaky

control flow had to be simplified.

save_tuple(): I believe the new code for TUPLE{1,2,3} in proto 2 was

incorrect for recursive tuples. Tried to repair; seems to work OK, but
there are no checked-in tests for this yet.

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).

Shouldn't test short tuples with all items equal -- one potential bug
...
would be that the tuple is reversed on unpickling, and we should catch
that. :-)
Goodnight -- that's it for toniht!

More protocol 2: TUPLE1, TUPLE2, TUPLE3.
...
Also moved the special case for empty tuples from save() to save_tuple().

Rename 'bin' arg to 'proto'. Keep the default at 0 lest the tests

change in meaning.

save_inst(): Rewrote to have only one branch on self.bin. Also got rid
...
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.

Fixed odd whitespace after "if", which I believe I introduced long ago.

Add a comment explaining that struct.pack() beats marshal.dumps(), but
...
marshal.loads() beats struct.unpack()! Possibly because the latter
creates a one-tuple. :-(
2003-01-28 03:17:21 +00:00
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.)
2003-01-28 03:03:08 +00:00

save_tuple(): Minor rewriting, and added a comment about the subtlety

created by recursive tuples.

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.
2003-01-28 01:15:46 +00:00

save_list(): removed unused local "d".

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

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.
2003-01-28 01:00:38 +00:00

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

Added XXX about save()'s special-casing of tuples -- I don't get it.

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.
