Tim Peters fdc03462b3 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).

Guido van Rossum 7d97d31a1b OK, this is really the last one tonight!
NEWFALSE and NEWTRUE.
2003-01-28 04:25:27 +00:00
Guido van Rossum 025bc2fe6c 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!
2003-01-28 04:20:02 +00:00
Guido van Rossum 44f0ea5f73 More protocol 2: TUPLE1, TUPLE2, TUPLE3.
Also moved the special case for empty tuples from save() to save_tuple().
2003-01-28 04:14:51 +00:00
Guido van Rossum 9d32bb1708 Rename 'bin' arg to 'proto'. Keep the default at 0 lest the tests
change in meaning.
2003-01-28 03:51:53 +00:00
Tim Peters 3b769835ca 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.
2003-01-28 03:51:36 +00:00
Guido van Rossum 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
Tim Peters 8fda7bc48d save_int(): Fixed two new off-by-1 glitches. 2003-01-28 03:40:52 +00:00
Guido van Rossum 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. :-(
2003-01-28 03:17:21 +00:00
Guido van Rossum 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
Tim Peters f558da0f90 save_tuple(): Minor rewriting, and added a comment about the subtlety
created by recursive tuples.
2003-01-28 02:09:55 +00:00
Tim Peters 209ad95b00 load_appends(): replaced .append() loop with an .extend(). 2003-01-28 01:44:45 +00:00
Tim Peters c23d18a955 Comments. 2003-01-28 01:41:51 +00:00
Tim Peters 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
Tim Peters 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.
2003-01-28 01:00:38 +00:00
Tim Peters 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
Tim Peters 22987e3cbd save_bool(): simplified. 2003-01-28 00:26:14 +00:00
Tim Peters cbd0a32d09 Repaired grammar in new comment. 2003-01-28 00:24:43 +00:00
Tim Peters b377f8ac3e clear_memo(): Repaired grammar in docstring. 2003-01-28 00:23:36 +00:00
Tim Peters e105478a0c Added one-line comments to the proto 2 opcodes. 2003-01-28 00:22:12 +00:00
Neal Norwitz 784a3f53a8 Use proper function name in exception messages 2003-01-28 00:20:41 +00:00
Tim Peters 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.

Tim Peters bdbe74183c Documented the 2's-comp business for the new long opcodes. 2003-01-27 23:54:04 +00:00
Tim Peters 5eed340267 Whitespace normalization. 2003-01-27 23:51:36 +00:00
Tim Peters 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.

Guido van Rossum 99d4abf8a2 Support socket timeout in SSL, by Geoff Talvola.
(SF patch #675750, to fix SF bug #675552.)

Guido van Rossum 5a2d8f5e9a Begin documenting protocol 2. 2003-01-27 21:44:25 +00:00
Tim Peters bb38e306ae Added some comments. 2003-01-27 21:25:41 +00:00
Tim Peters e46b73f5b3 memoize(): Reworded the docs to try to disentangle the Pickler's memo
dict from the Unpickler's memo (which is a different beast!).
2003-01-27 21:22:10 +00:00
Tim Peters bbf63cd05c Using marshal functions to pack & unpack 1-byte ints is an obscure &
expensive way to spell chr() and ord().
2003-01-27 21:15:36 +00:00
Tim Peters 22a449aacc Added a brief comment to each pickle opcode declaration. 2003-01-27 20:16:36 +00:00
Guido van Rossum a72ded9bc8 Remove a stray quote. 2003-01-27 19:40:47 +00:00
Tim Peters 1996e23054 Repaired comment. 2003-01-27 19:38:34 +00:00
Tim Peters 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.

Tim Peters 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>.

Tim Peters 40e1ce4d73 Repaired spelling of "test_iconv_codecs" in various expected-skip lists. 2003-01-27 16:45:03 +00:00

Fred Drake 0a9cc58c85 Adjust some of Skip's latest changes slightly; these really are things
that should stand out.
2003-01-27 16:32:04 +00:00
Fred Drake 9db20c62ff Make the "notice" environments somewhat similar, with less difference
between the "note" and "warning" flavors.
2003-01-27 16:31:16 +00:00
Andrew M. Kuchling 6ffdaab808 Remove the recently-added get_distutil_options(), and just
have two tuples listing the legal keywords for setup() and Extension()
