Tim Peters e63415ead8 SF patch #421922: Implement rich comparison for dicts.
d1 == d2 and d1 != d2 now work even if the keys and values in d1 and d2
don't support comparisons other than ==, and testing dicts for equality
is faster now (especially when inequality obtains).

Jeremy Hylton 66a7e57c7e Fix several bugs and add two features.
Assertion error message had typos in arguments to string format.

.cover files for modules in packages are now put in the right place.

The code that generate .cover files seemed to prepend a "./" to many
absolute paths, causing them to fail.  The code now checks explicitly
for absolute paths and leaves them alone.

In trace/coverage code, recover from case where module has no __name__
attribute, when e.g. it is executed by PyRun_String().  In this case,
assign modulename to None and hope for the best.  There isn't anywhere
to write out coverage data for this code anyway.

Also, replace several sys.stderr.writes with print >> sys.stderr.

New features:

-C/--coverdir dir: Generate .cover files in specified directory
instead of in the directory where the .py file is.

-s: Print a short summary of files coverred (# lines, % coverage,
name)

Jeremy Hylton 9c90105cb0 Several small changes. Mostly reformatting, adding parens.
Check for free in class and method only if nested scopes are enabled.

Add assertion to verify that no free variables occur when nested
scopes are disabled.

XXX When should nested scopes by made non-optional on the trunk?

Tim Peters 7ae2229afb This is a test showing SF bug 422177. It won't trigger until I check in
another change (to test_import.py, which simply imports the new file).  I'm
checking this piece in now, though, to make it easier to distribute a patch
for x-platform checking.

Tim Peters 6d60b2e762 SF bug #422108 - Error in rich comparisons.
2.1.1 bugfix candidate too.
Fix a bad (albeit unlikely) return value in try_rich_to_3way_compare().
Also document do_cmp()'s return values.

Fred Drake b638aafef2 Michael Hudson <mwh21@cam.ac.uk>:
This patch does several things to termios:

(1) changes all functions to be METH_VARARGS
(2) changes all functions to be able to take a file object as the
    first parameter, as per

http://mail.python.org/pipermail/python-dev/2001-February/012701.html

(3) give better error messages
(4) removes a bunch of comments that just repeat the docstrings
(5) #includes <termio.h> before #including <sys/ioctl.h> so more
    #constants are actually #defined.
(6) a couple of docstring tweaks

I have tested this minimally (i.e. it builds, and
doesn't blow up too embarassingly) on OSF1/alpha and
on one of the sf compile farm's solaris boxes, and
rather more comprehansively on my linux/x86 box.

It still needs to be tested on all the other platforms
we build termios on.


This closes the code portion of SF patch #417081.

Fred Drake a8e0827614 Hmm... better add a version annotation for the Iterator Protocol section. 2001-05-07 17:47:07 +00:00
Fred Drake dbcaeda79a Added documentation for PyIter_Check() and PyIter_Next().
Wrapped a long line.

Tim Peters 8572b4fedf Generalize zip() to work with iterators.
NEEDS DOC CHANGES.
More AttributeErrors transmuted into TypeErrors, in test_b2.py, and,
again, this strikes me as a good thing.
This checkin completes the iterator generalization work that obviously
needed to be done.  Can anyone think of others that should be changed?

Tim Peters ef0c42d4e5 Get rid of silly 5am "del" stmts. 2001-05-05 21:36:52 +00:00
Tim Peters cb8d368b82 Reimplement PySequence_Contains() and instance_contains(), so they work
safely together and don't duplicate logic (the common logic was factored
out into new private API function _PySequence_IterContains()).
Visible change:
    some_complex_number  in  some_instance
no longer blows up if some_instance has __getitem__ but neither
__contains__ nor __iter__.  test_iter changed to ensure that remains true.
2001-05-05 21:05:01 +00:00
Andrew M. Kuchling a8defaae04 Skeletal version; I'm checking this in now so I can keep a list of changes,
but don't plan on actually writing any text until, ooh, say, July or
   thereabouts.

Tim Peters de9725f135 Make 'x in y' and 'x not in y' (PySequence_Contains) play nice w/ iterators.
NEEDS DOC CHANGES
A few more AttributeErrors turned into TypeErrors, but in test_contains
this time.
The full story for instance objects is pretty much unexplainable, because
instance_contains() tries its own flavor of iteration-based containment
testing first, and PySequence_Contains doesn't get a chance at it unless
instance_contains() blows up.  A consequence is that
    some_complex_number in some_instance
dies with a TypeError unless some_instance.__class__ defines __iter__ but
does not define __getitem__.
2001-05-05 10:06:17 +00:00
Tim Peters 2cfe368283 Make unicode.join() work nice with iterators. This also required a change
to string.join(), so that when the latter figures out in midstream that
it really needs unicode.join() instead, unicode.join() can actually get
all the sequence elements (i.e., there's no guarantee that the sequence
passed to string.join() can be iterated over *again* by unicode.join(),
so string.join() must not pass on the original sequence object anymore).
2001-05-05 05:36:48 +00:00
Tim Peters 432b42aa4c Mark string.join() as done. Turns out string_join() works "for free" now,
because PySequence_Fast() started working for free as soon as
PySequence_Tuple() learned how to work with iterators.  For some reason
unicode.join() still doesn't work, though.
2001-05-05 04:24:43 +00:00
Tim Peters 12d0a6c78a Fix a tiny and unlikely memory leak. Was there before too, and actually
several of these turned up and got fixed during the iteration crusade.
2001-05-05 04:10:25 +00:00
Tim Peters 6912d4ddf0 Generalize tuple() to work nicely with iterators.
NEEDS DOC CHANGES.
This one surprised me!  While I expected tuple() to be a no-brainer, turns
out it's actually dripping with consequences:
1. It will *allow* the popular PySequence_Fast() to work with any iterable
   object (code for that not yet checked in, but should be trivial).
2. It caused two std tests to fail.  This because some places used
   PyTuple_Sequence() (the C spelling of tuple()) as an indirect way to test
   whether something *is* a sequence.  But tuple() code only looked for the
   existence of sq->item to determine that, and e.g. an instance passed
   that test whether or not it supported the other operations tuple()
   needed (e.g., __len__).  So some things the tests *expected* to fail
   with an AttributeError now fail with a TypeError instead.  This looks
   like an improvement to me; e.g., test_coercion used to produce 559
   TypeErrors and 2 AttributeErrors, and now they're all TypeErrors.  The
   error details are more informative too, because the places calling this
   were *looking* for TypeErrors in order to replace the generic tuple()
   "not a sequence" msg with their own more specific text, and
   AttributeErrors snuck by that.

Tim Peters f4848dac41 Make PyIter_Next() a little smarter (wrt its knowledge of iterator
internals) so clients can be a lot dumber (wrt their knowledge).

Tim Peters 3e067578f6 Added reminders to make some remaining functions iterator-friendly. Feel
free to do one!

Tim Peters 4e9afdca39 Generalize map() to work with iterators.
NEEDS DOC CHANGES.
Possibly contentious:  The first time s.next() yields StopIteration (for
a given map argument s) is the last time map() *tries* s.next().  That
is, if other sequence args are longer, s will never again contribute
anything but None values to the result, even if trying s.next() again
could yield another result.  This is the same behavior map() used to have
wrt IndexError, so it's the only way to be wholly backward-compatible.
I'm not a fan of letting StopIteration mean "try again later" anyway.
2001-05-03 23:54:49 +00:00
Fred Drake 6aebded915 The weakref support in PyObject_InitVar() as well; this should have come out
at the same time as it did from PyObject_Init() .
2001-05-03 20:04:33 +00:00
Fred Drake ba40ec42c8 Remove unnecessary intialization for the case of weakly-referencable objects;
the code necessary to accomplish this is simpler and faster if confined to
the object implementations, so we only do this there.

This causes no behaviorial changes beyond a (very slight) speedup.
2001-05-03 19:44:50 +00:00
Fred Drake 9b03e59deb Remove an obsolete comment and a "return" before fallig off the end of a
void function.
2001-05-03 16:05:46 +00:00
Fred Drake 4dcb85b817 Since Py_TPFLAGS_HAVE_WEAKREFS is set in Py_TPFLAGS_DEFAULT, it does not
need to be specified in the type structures independently.  The flag
exists only for binary compatibility.

This is a "source cleanliness" issue and introduces no behavioral changes.

Fred Drake 72987a4b96 Make the Mailbox objects support iteration -- they already had the
appropriate next() method, and this is what people really want to do with
these objects in practice.

Marc-André Lemburg 6f15e5796e Added new parser markers 'et' and 'et#' which do not recode string
objects but instead assume that they use the requested encoding.

This is needed on Windows to enable opening files by passing in
Unicode file names.

Guido van Rossum b1f35bffe5 Mchael Hudson pointed out that the code for detecting changes in
dictionary size was comparing ma_size, the hash table size, which is
always a power of two, rather than ma_used, wich changes on each
insertion or deletion.  Fixed this.
