Tim Peters c77db34575 SF bug [#473864] doctest expects spurios space.
Repair unlikely surprise due to magical softspace attr and the use of
print with a trailing comma in doctest examples.
Bugfix candidate.

Tim Peters 17111f3b24 SF bug [#467336] doctest failures w/ new-style classes.
Taught doctest about static methods, class methods, and property docstrings
in new-style classes.  As for inspect.py/pydoc.py before it, the new stuff
needed didn't really fit into the old architecture (but was less of a
strain to force-fit here).
New-style class docstrings still aren't found, but that's the subject
of a different bug and I want to fix that right instead of hacking around
it in doctest.

Tim Peters 4a9ac4a83c SF patch [#466616] Exclude imported items from doctest.
Another installment; the new functionality wasn't actually enabled in
normal use, only in the strained use checked by the test case.

Tim Peters 7402f791a4 SF patch [#466616] Exclude imported items from doctest,
from Tim Hochberg.  Also mucho fiddling to change the way doctest
determines whether a thing is a function, module or class.  Under 2.2,
this really requires the functions in inspect.py (e.g., types.ClassType
is close to meaningless now, if not outright misleading).

Tim Peters 4fd9e2fc13 Remove the horrid generators hack from doctest.py. This relies on a
somewhat less horrid hack <wink>:  if a module does
    from __future__ import X
then the module dict D is left in a state such that (viewing X as a
string)
    D[X] is getattr(__future__, X)
So by examining D for all the names of future features, and making that
test for each, we can make a darned good guess as to which future-features
were imported by the module.  The appropriate flags are then sucked out
of the __future__ module, and passed on to compile()'s new optional
arguments (PEP 264).

Also gave doctest a meaningful __all__, removed the history of changes
(CVS serves that purpose now), and removed the __version__ vrbl (similarly;
before CVS, it was a reasonable clue, but not anymore).

Tim Peters 03813399cc Document doctest's generator-future hack. 2001-07-16 18:39:58 +00:00
Tim Peters fe2127d3cb Ugly. A pile of new xxxFlags() functions, to communicate to the parser
that 'yield' is a keyword.  This doesn't help test_generators at all!  I
don't know why not.  These things do work now (and didn't before this
patch):

1. "from __future__ import generators" now works in a native shell.

2. Similarly "python -i xxx.py" now has generators enabled in the
   shell if xxx.py had them enabled.

3. This program (which was my doctest proxy) works fine:

from __future__ import generators

source = """\
def f():
    yield 1
"""

exec compile(source, "", "single") in globals()
print type(f())

Tim Peters fee69d0313 Changed some comments. Removed the caution about clearing globs, since
clearing a shallow copy _run_examples() makes itself can't hurt anything.

Tim Peters d4ad59e1eb Clear the copy of the globs dict after running examples. This helps to
break cycles, which are a special problem when running generator tests
that provoke exceptions by invoking the .next() method of a named
generator-iterator:  then the iterator is named in globs, and the
iterator's frame gets a tracekback object pointing back to globs, and
gc doesn't chase these types so the cycle leaks.

Also changed _run_examples() to make a copy of globs itself, so its
callers (direct and indirect) don't have to (and changed the callers
to stop making their own copies); *that* much is a change I've been
meaning to make for a long time (it's more robust the new way).

Here's a way to provoke the symptom without doctest; it leaks at a
prodigious rate; if the last two "source" lines are replaced with
    g().next()
the iterator isn't named and then there's no leak:

source = """\
def g():
    yield 1/0

k = g()
k.next()
"""

code = compile(source, "<source>", "exec")

def f(globs):
    try:
        exec code in globs
    except ZeroDivisionError:
        pass

while 1:
    f(globals().copy())

After this change, running test_generators in an infinite loop still leaks,
but reduced from a flood to a trickle.

Tim Peters 77f2d504c3 doctest systematically leaked memory when handling an exception in an
example (an obvious trackback cycle).  Repaired.

Tim Peters 08bba953ea doctest doesn't handle intentional SyntaxError exceptions gracefully,
because it picks up the first line of traceback.format_exception_only()
instead of the last line.  Pick up the last line instead!

Tim Peters 24a4191160 Changed doctest to run tests in alphabetic order of name.
This makes verbose-mode output easier to dig thru, and removes an accidental
dependence on the order of dict.items() (made visible by recent changes to
dictobject.c).

from the last failure report.

Tim Peters f9bb4969af Miranda newlines: if anything at all was written to stdout, supply a
newline at the end if there isn't one already.  Expected output has no
way to indicate that a trailing newline was not expected, and in the
interpreter shell *Python* supplies the trailing newline before printing
the next prompt.
