Tim Peters ce70a3b306 Whitespace normalization. 2006-07-27 23:45:48 +00:00
Barry Warsaw 00decd7835 Patch #1520294: Support for getset and member descriptors in types.py,
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.

Armin Rigo dd5c023af5 some more fixes and tests for inspect.getsource(), triggered by crashes
from the PyPy project as well as the SF bug #1295909.

Johannes Gijsbers a5855d5ace Patch #1159931/bug #1143895: inspect.getsource failed when functions,
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

Johannes Gijsbers 1542f34c42 Patch #1011890: fix inspect.getsource breaking with line-continuation &
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.

Skip Montanaro 41f89a4f3d Sort classes by fully qualified name. In the common case where you are
displaying a set of classes from one module it doesn't matter, but if you
are displaying a large class tree from multiple modules it improves the
display to sort by module.name.

Johannes Gijsbers 9324526a76 Use __module__ attribute when available instead of using isclass() predicate
(functions and methods have grown the __module__ attribute too). See bug #570300.

Johannes Gijsbers c473c99d16 Patch #1006219: let inspect.getsource show '@' decorators and add tests for
this (which are rather ugly, but it'll have to do until test_inspect gets a
major overhaul and a conversion to unittest). Thanks Simon Percivall!

Matthias Klose 2e829c0214 - Bug #891637, patch #1005466: fix inspect.getargs() crash on def foo((bar)). 2004-08-15 17:04:33 +00:00
Brett Cannon b3de2e13ba 'inspect' was not listing the functions in a module properly if the module was
reached through a symlink (was comparing path of module to path to function and
were not matching because of the symlink).  os.path.realpath() is now used to
solve this discrepency.

Closes bug #570300.  Thanks Johannes Gijsbers for the fix.

Jeremy Hylton b4c17c8992 Fix getcomments() so that it doesn't fail with TypeErrors.
It appears that getcomments() can get called for classes defined in
C.  Since these don't have source code, it can't do anything useful.
A function buried many levels deep was raising a TypeError that was
not caught.

Who knows why this broke...

Tim Peters 13b49d3374 New function classify_class_attrs(). As a number of SF bug reports
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).
2001-09-23 02:00:29 +00:00
Tim Peters e0b2d7ac9a Add a function to compute a class's method resolution order. This is
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.
2001-09-22 06:10:55 +00:00
Tim Peters f1d90b965e Ensure that isfunction(obj) and (the new) ismethoddescriptor(obj) never
both return true.  This restores pydoc's ability to deduce argument lists
for functions and methods coded in Python.
