Replace section 4.1 with section A.3.
The new section 4.1 is titled "Naming and binding." It includes the
text of section A.3 augmented with some of the detailed text from the
old section 4.1.
The \dfn, \index stuff is probably wrong, but I tried.
Also update other parts of appendix A to mention that nested scopes
and generators are standard features.
possible pool states. I think it's much clearer now.
Added a new long overdue block-management overview comment block.
I believe the comments are in good shape now.
Added two comments about possible small optimizations (one getting rid
of runtime multiplications at the cost of a new pool_header member; the
other getting rid of runtime divisions and the pool_header capacity
member, at the cost of a static const vector of 32 uints).
Split the description of co_flags into two paragraphs. The first
describes the flags that are used for non-future purposes, where
CO_GENERATOR was added. The second describes __future__'s use of
co_flags and mentions the only one currently meaningful,
CO_FUTURE_DIVISION.
This displays stats about the # of arenas, pools, blocks and bytes, to
stderr, both used and reserved but unused.
CAUTION: Because PYMALLOC_DEBUG is on, the debug malloc routine adds
16 bytes to each request. This makes each block appear two size classes
higher than it would be if PYMALLOC_DEBUG weren't on.
So far, playing with this confirms the obvious: there's a lot of activity
in the "small dict" size class, but nothing in the core makes any use of
the 8-byte or 16-byte classes.
I really can't test this, but from reading the discussion in that bug
report, it's likely that this works. It may also close a whole bunch
of other bug reports related to urllib and proxies on Windows, but who
knows.
Convert METH_OLDARGS -> METH_VARARGS: also PyArg_Parse -> PyArg_ParseTuple
Convert METH_OLDARGS -> METH_NOARGS: remove args parameter
Please review. All tests pass, but some modules don't have tests.
I spot checked various functions to try to make sure nothing broke.
the code so that the most frequent cases come first. Added comments.
Found a hidden assumption that a pool contains room for at least two
blocks, and added an assert to catch a violation if it ever happens in
a place where that matters. Gave the normal "I allocated this block"
case a longer basic block to work with before it has to do its first
branch (via breaking apart an embedded assignment in an "if", and
hoisting common code out of both branches).
