Brett Cannon 82a9394237 Add doc discussing how AST compiler is structured and designed. 
It is out of date, though, thanks to lacking info on the arena API.  It also
should eventually be removed in favor of updating PEP 339.

Jeremy Hylton c960f26044 Improved handling of syntax errors. 
Expand set of errors caught in set_context().  Some new errors, some
old error messages changed for consistency.

Fixed error checking in generator expression code.  The first set of
tests were impossible condition given the grammar.  In general, the
ast code uses REQ() for those sanity checks.

Fix some error handling for augmented assignments.  As comments in the
code explain, set_context() ought to work here, but I got unexpected
crashes when I tried it.  Should come back to this.

Add note to Grammar that yield expression is a special case.

Add doctest cases for SyntaxErrors raised by ast.c.

Tim Peters 5db42c4c50 alias_for_import_name(): Dueling compiler warnings ;-) 
Squash new warnings from VC 7.1 about mixing signed and
unsigned types in comparisons.  I can see why `len` was
changed to size_t here, but don't see why `i` was also
changed.  Change `i` back to int.

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.

Barry Warsaw 2a38a86c1c Expose Subversion revision number (calculated via "svnversion .") to Python. 
Add C API function Py_GetBuildNumber(), add it to the interactive prompt
banner (i.e. Py_GetBuildInfo()), and add it as the sys.build_number
attribute.  The build number is a string instead of an int because it may
contain a trailing 'M' if there are local modifications.

Neal Norwitz f599f424a2 SF patch #1355913, PEP 341 - Unification of try/except and try/finally

 2005-12-17 21:33:47 +00:00
Neal Norwitz adb69fcdff Merge from ast-arena. This reduces the code in Python/ast.c by ~300 lines, 
simplifies a lot of error handling code, and fixes many memory leaks.

Neal Norwitz 6f0d479c78 Fix an int/long mismatch identified here:

Neal Norwitz 897ff817d5 SF #1373150, diffs in working copy after a build 
Strip off leading dots and slash so the generated files are the same regardless
of whether you configure in the checkout directory or build.

If anyone configures in a different directory, we might want a cleaner
approach using os.path.*().  Hopefully this is good enough.
 2005-12-11 21:18:22 +00:00
Neal Norwitz f8d403dd97 SF #1377897, Bus error in ast 
If a line had multiple semi-colons and ended with a semi-colon, we would
loop too many times and access a NULL node.  Exit the loop early if
there are no more children.
 2005-12-11 20:12:40 +00:00
Neal Norwitz 8ad64aaacc SF #1370197, memory leak - ast_error_finish (in error conditions). 2005-12-11 20:08:33 +00:00
Jeremy Hylton af68c874a6 Add const to several API functions that take char *. 
In C++, it's an error to pass a string literal to a char* function
without a const_cast().  Rather than require every C++ extension
module to put a cast around string literals, fix the API to state the
const-ness.

I focused on parts of the API where people usually pass literals:
PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type
slots, etc.  Predictably, there were a large set of functions that
needed to be fixed as a result of these changes.  The most pervasive
change was to make the keyword args list passed to
PyArg_ParseTupleAndKewords() to be a const char *kwlist[].

One cast was required as a result of the changes:  A type object
mallocs the memory for its tp_doc slot and later frees it.
PyTypeObject says that tp_doc is const char *; but if the type was
created by type_new(), we know it is safe to cast to char *.

Neal Norwitz 37c0844b35 Fix SF bug #1167751, Argument genexp corner case 
Incorrect code was generated for:

  foo(a = i for i in range(10))

This should have generated a SyntaxError.  Fix the Grammar so
it raises a SyntaxError and test it.

I'm uncertain whether this should be backported.  It makes
something that was Syntactically valid invalid.  However,
the code would either be completely broken or do the wrong thing.
