__init__.py module to raise errors which can be catched as LookupErrors
as well as SystemErrors.
Modified the error messages to include more information about the
failing module.
instance.
Split a string comparison test in two halves, replacing "a==b==a" with
separate tests for a==b and b==a. (Reason: while experimenting, this
test failed, and I wanted to know if it was the first or the second ==
operator that failed.)
complex_coerce() would never be called with a complex argument,
because PyNumber_Coerce[Ex] doesn't bother calling the type's coercion
method if the values already have the same type. But now, of course,
it's possible to pass an instance of a complex *subtype*, and those
must be accepted.
hack, and it's even more disgusting than a PyInstance_Check() call.
If the tp_compare slot is the slot used for overrides in Python,
it's always called.
Add some tests that show what should work too.
only safely call a type's tp_compare slot if the second argument is
also an instance of the same type. I hate to think what
e.g. int_compare() would do with a second argument that's a float!
#462270: sub-tle difference between pre.sub and sre.sub. PRE ignored
an empty match at the previous location, SRE didn't.
also synced with Secret Labs "sreopen" codebase.
on file.__methods__. Since the docs say "This module will become obsolete
in a future release", this is just a quick hack to stop it from blowing
up. If you care about this module, test it! It doesn't make much sense

descriptors for each attribute. The getattr() implementation is
similar to PyObject_GenericGetAttr(), but delegates to im_self instead
of looking in __dict__; I couldn't do this as a wrapper around
PyObject_GenericGetAttr().
XXX A problem here is that this is a case of *delegation*. dir()
doesn't see exactly the same attributes that are actually defined;
e.g. if the delegate is a Python function object, it supports
attributes like func_code etc., but these are not visible to dir(); on
the other hand, dynamic function attributes (stored in the function's
__dict__) *are* visible to dir(). Maybe we need a mechanism to tell
dir() about the delegation mechanism? I vaguely recall seeing a
request in the newsgroup for a more formal definition of attribute
delegation too. Sigh, time for a new PEP.
to raise TypeError. In practice, a disallowed attribute assignment
can raise either TypeError or AttributeError (and it's unclear which
is better). So allow either. (Yes, this is in anticipation of a
code change that switches the exception raised. :-)
- Add a utility function, cantset(), which verifies that setting a
particular attribute to a given value is disallowed, and also that
deleting that same attribute is disallowed. Use this in the
test_func_*() tests.
- Add a new set of tests that test conformance of various instance
method attributes. (Also in anticipation of code that changes their
implementation.)
compile() becomes replacement for builtin compile()
compileFile() generates a .pyc from a .py
both are exported in __init__
compiler.parse() gets optional second argument to specify compilation
mode, e.g. single, eval, exec
Add AbstractCompileMode as parent class and Module, Expression, and
Interactive as concrete subclasses. Each corresponds to a compilation
mode.
THe AbstractCompileMode instances in turn delegate to CodeGeneration
subclasses specialized for their particular functions --
ModuleCodeGenerator, ExpressionCodeGeneration,
InteractiveCodeGenerator.
The argument properties are ordered from easiest to hardest. The
harder the arg, the more complicated that code that must be generated
to return it from getChildren() and/or getChildNodes(). The old
calculation routine was bogus, because it always set hardest_arg to
the hardness of the last argument. Now use max() to always set it to
the hardness of the hardest argument.
Remove the only test in the syntax module. It ends up that the
transformer must handle this error case.
In the transformer, check for a list compression in com_assign_list()
by looking for a list_for node where a comma is expected.
In pycodegen.compile() re-raise the SyntaxError rather than catching
it and exiting
Renamed the 'readonly' field to 'flags' and defined some new flag
bits: READ_RESTRICTED and WRITE_RESTRICTED, as well as a shortcut
RESTRICTED that means both.
