inspect.py, and pydoc.py. Specifically, this allows for querying the type of
an object against these built-in C types and more importantly, for getting
their docstrings printed in the interactive interpreter's help() function.
This patch includes a new built-in module called _types which provides
definitions of getset and member descriptors for use by the types.py module.
These types are exposed as types.GetSetDescriptorType and
types.MemberDescriptorType. Query functions are provided as
inspect.isgetsetdescriptor() and inspect.ismemberdescriptor(). The
implementations of these are robust enough to work with Python implementations
other than CPython, which may not have these fundamental types.
The patch also includes documentation and test suite updates.
I commit these changes now under these guiding principles:
1. Silence is assent. The release manager has not said "no", and of the few
people that cared enough to respond to the thread, the worst vote was "0".
2. It's easier to ask for forgiveness than permission.
3. It's so dang easy to revert stuff in svn, that you could view this as a
forcing function. :)
Windows build patches will follow.
def foo((x)): was getting recognized as requiring tuple unpacking
which is not correct.
Add tests for this case and the proper way to unpack a tuple of one:
def foo((x,)):
test_inpsect was incorrect before. I'm not sure why it was passing,
but that has been corrected with a test for both functions above.
This means the test (and therefore inspect.getargspec()) are broken in 2.4.
etc., had comments after the colon, and some other cases. This patch
take a simpler approach that doesn't rely on looking for a ':'. Thanks
Simon Percivall!
more. Thanks to Simon Percivall!
The patch makes changes to inspect.py in two places:
* the pattern to match against functions at line 436 is
modified: lambdas should be matched even if not
preceded by whitespace, as long as "lambda" isn't part
of another word.
* the BlockFinder class is heavily modified. Changes are:
- checking for "def", "class" or "lambda" names
before setting self.started to True. Then checking the
same line for word characters after the colon (if the
colon is on that line). If so, and the line does not
end with a line continuation marker, raise EndOfBlock
immediately.
- adding self.passline to show that the line is to be
included and no more checking is necessary on that
line. Since a NEWLINE token is not generated when a
line continuation marker exists, this allows getsource
to continue with these functions even if the following
line would not be indented.
Also add a bunch of
'quite-unlikely-to-occur-in-real-life-but-working-anyway' tests.
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".
This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).
Now Tim and Jack can have at it. :)
point out, pydoc doesn't tell you where class attributes were defined,
gets several new 2.2 features wrong, and isn't aware of some new features
checked in on Thursday <wink>. pydoc is hampered in part because
inspect.py has the same limitations. Alas, I can't think of a way to
fix this within the current architecture of inspect/pydoc: it's simply
not possible in 2.2 to figure out everything needed just from examining
the object you get back from class.attr. You also need the class
context, and the method resolution order, and tests against various things
that simply didn't exist before. OTOH, knowledge of how to do that is
getting quite complex, so doesn't belong in pydoc.
classify_class_attrs takes a different approach, analyzing all
the class attrs "at once", and returning the most interesting stuff for
each, all in one gulp. pydoc needs to be reworked to use this for
classes (instead of the current "filter dir(class) umpteen times against
assorted predicates" approach).
easy for 2.2 new-style classes, but trickier for classic classes, and
different approaches are needed "depending". The function will allow
later code to treat all flavors of classes uniformly.
