- Use xdis 3.0.0 protocol load_module. Needs bump in requirements.txt
and _pkg_info_.py
- Start Python 1.5 decompiling - another round of work is needed to remove
bugs
- small cleanups
This bug had possibly caused lots of grammar pollution which may need
addressing.
We want to process COME_FROMs to the same offset to be in *descending*
order so we have the larger range or biggest instruction interval
last. (I think they are sorted in increasing order, but for safety
we sort them). That way, specific COME_FROM tags will match up
properly. For example, a "loop" with an "if" nested in it should have
the "loop" tag last so the grammar rule matches that properly
Adjust Python 3 grammar for more COME_FROM -> COME_FROM_LOOP. And
remove optional COME_FROM_LOOP where possible. Previously, the
optional-ness was a result of inner nestings gobbling up the
COME_FROM.
We'll probably want to go back and fix this up in Python2.
Fix py.test pytest/test_grammar.py -
Comprehension sorts of things removed from parser that
don't exist in earlier pythons
scanners/tok.py Add back in "to" when needed
As part of tokenization for (de)parsing, we need to do something like a
disassembly, but is is really a little different.
Disassembly, strictly speaking, is done by the xdis module now.
What "ingestion" does is massage the instruction tokens to a form that is
more amenable for parsing.
In sum, ingestion is different than disassembly, although disassembly is
generally the first part of ingestion.
The scheme for turning 2.6 bytecode into 2.7 psuedo bytecode
I think is a lose.
I won't work for fragment handling.
Instead, change the grammar and syntax rules
This also has the benefits:
* We see how code generation changed over releases
by looking at grammar and semantic rules rather
than arbitrary code
* We can better assocate with what's running
(in a sense this is a restatement of broken fragment
handling)
* With the right structure in place we are in a better position to
handle 2.5, 2.4, etc. That is, after a while, the incremental changes
to get say from python 2.3 bytecode to python 2.7 are great.
