Neal Norwitz 84167d09cd Even though _Py_Mangle() isn't truly public anyone can call it and
there was no verification that privateobj was a PyString.  If it wasn't
a string, this could have allowed a NULL pointer to creep in below and crash.

I wonder if this should be PyString_CheckExact?  Must identifiers be strings
or can they be subclasses?

Neal Norwitz 0cbd805a10 Bug #1333982: string/number constants were inappropriately stored
in the byte code and co_consts even if they were not used, ie
immediately popped off the stack.

Neal Norwitz 4ffedadb10 Bug #1191458: tracing over for loops now produces a line event
on each iteration.  I'm not positive this is the best way to handle
this.  I'm also not sure that there aren't other cases where
the lnotab is generated incorrectly.  It would be great if people
that use pdb or tracing could test heavily.

Also:
 * Remove dead/duplicated code that wasn't used/necessary
   because we already handled the docstring prior to entering the loop.
 * add some debugging code into the compiler (#if 0'd out).

Neal Norwitz f71847e645 If the for loop isn't entered, entryblock will be NULL. If passed
to stackdepth_walk it will be dereffed.

Not sure if I found with failmalloc or Klockwork #55.

Guido van Rossum da5b701aee Get rid of __context__, per the latest changes to PEP 343 and python-dev
discussion.
There are two places of documentation that still mention __context__:
Doc/lib/libstdtypes.tex -- I wasn't quite sure how to rewrite that without
spending a whole lot of time thinking about it; and whatsnew, which Andrew
usually likes to change himself.

Anthony Baxter 2c33fc77fe per Jeremy's email, remove the _WITH_CAST versions of macros. g++
still has errors from the casts of asdl_seq_GET to cmpop_ty, but
otherwise it's C++ clean.

Anthony Baxter 7b782b61c5 more low-hanging fruit to make code compile under a C++ compiler. Not
entirely happy with the two new VISIT macros in compile.c, but I
couldn't see a better approach.

Jeremy Hylton ed40ea1159 Generate line number table entries for except handlers.
Re-enable all the tests in test_trace.py except one.  Still not sure that these tests test what they used to test, but they pass.  One failing test seems to be caused by undocumented line number table behavior in Python 2.4.

Guido van Rossum f669436189 Um, I thought I'd already checked this in.
Anyway, this is the changes to the with-statement
so that __exit__ must return a true value in order
for a pending exception to be ignored.
The PEP (343) is already updated.

Thomas Wouters 5e9f1fa706 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.

2006-02-28 19:02:24 +00:00
Thomas Wouters f7f438ba3b 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.

Guido van Rossum c2e20744b2 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).

Thomas Wouters 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 ;)

Neal Norwitz 51abbc7b4a 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.
