Tabify and reflow some long lines.

Much of the peephole optimizer is now indented badly, but it's about
to be revised anyway.

Generally inehrit codeflags that are in PyCF_MASK, instead of writing it out
...
in multiple places. This makes compile()/eval()/etc also inherit the
absolute-import codeflag, like division and with-statement already were.

SF patch #1438387 , PEP 328: relative and absolute imports.
...
- IMPORT_NAME takes an extra argument from the stack: the relativeness of
the import. Only passed to __import__ when it's not -1.
- __import__() takes an optional 5th argument for the same thing; it
__defaults to -1 (old semantics: try relative, then absolute)
- 'from . import name' imports name (be it module or regular attribute)
from the current module's *package*. Likewise, 'from .module import name'
will import name from a sibling to the current module.
- Importing from outside a package is not allowed; 'from . import sys' in a
toplevel module will not work, nor will 'from .. import sys' in a
(single-level) package.
- 'from __future__ import absolute_import' will turn on the new semantics
for import and from-import: imports will be absolute, except for
from-import with dots.
Includes tests for regular imports and importhooks, parser changes and a
NEWS item, but no compiler-package changes or documentation changes.

PEP 343 -- the with-statement.
...
This was started by Mike Bland and completed by Guido
(with help from Neal).
This still needs a __future__ statement added;
Thomas is working on Michael's patch for that aspect.
There's a small amount of code cleanup and refactoring
in ast.c, compile.c and ceval.c (I fixed the lltrace
behavior when EXT_POP is used -- however I had to make
lltrace a static global).

dca3b9c797
PEP 308 implementation, including minor refdocs and some testcases. It
...
breaks the parser module, because it adds the if/else construct as well as
two new grammar rules for backward compatibility. If no one else fixes
parsermodule, I guess I'll go ahead and fix it later this week.
The TeX code was checked with texcheck.py, but not rendered. There is
actually a slight incompatibility:
>>> (x for x in lambda:0)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: iteration over non-sequence
changes into
>>> (x for x in lambda: 0)
File "<stdin>", line 1
(x for x in lambda: 0)
^
SyntaxError: invalid syntax
Since there's no way the former version can be useful, it's probably a
bugfix ;)

Fix Armin's bug 1333982. He found it, he didn't created it :-)
...
This code generated a C assertion:
assert 1, ([s for s in x] +
[s for s in x])
pass
assert was completely broken, it needed to use the proper block.
compiler_use_block() is now no longer used, so remove it.

Merge ast-branch to head
...
This change implements a new bytecode compiler, based on a
transformation of the parse tree to an abstract syntax defined in
Parser/Python.asdl.
The compiler implementation is not complete, but it is in stable
enough shape to run the entire test suite excepting two disabled
tests.

PEP 342 implementation. Per Guido's comments, the generator throw()

method still needs to support string exceptions, and allow None for the
third argument. Documentation updates are needed, too.

07359a7fed
Document how the pattern recognizer keeps all of its references in bounds.
...
Add a test in case the underlying assumptions ever change (i.e. the
compiler starts generating code blocks that are not punctuated by
RETURN_VALUE).

80121491e0
Teach the peepholer to fold unary operations on constants.
...
Afterwards, -0.5 loads in a single step and no longer requires a runtime
UNARY_NEGATIVE operation.

Transform "x in (1,2,3)" to "x in frozenset([1,2,3])".
...
Inspired by Skip's idea to recognize the throw-away nature of sequences
in this context and to transform their type to one with better performance.
2005-02-06 22:05:42 +00:00
9feb267caf
Do not fold a constant if a large sequence will result.
...
Saves space in the presence of code like: (None,)*10000

664b43b3f4
Re-running python with/without the -Qnew flag uses incorrectly optimized

bytecodes from the previously saved .pyc files. Fixed by disabling the static
optimization of BINARY_DIVIDE between two constants.
