Guido van Rossum 1031582388 Add more news about iterators. 2001-05-01 20:54:30 +00:00
Tim Peters f553f89d45 Generalize list(seq) to work with iterators. This also generalizes list()
to no longer insist that len(seq) be defined.
NEEDS DOC CHANGES.
This is meant to be a model for how other functions of this ilk (max,
filter, etc) can be generalized similarly.  Feel encouraged to grab your
favorite and convert it!
Note some cute consequences:
    list(file) == file.readlines() == list(file.xreadlines())
    list(dict) == dict.keys()
    list(dict.iteritems()) = dict.items()
    list(xrange(i, j, k)) == range(i, j, k)

Guido van Rossum 47668928e6 Discard a misleading comment about iter_iternext(). 2001-05-01 17:01:25 +00:00
Guido van Rossum 4f288ab7d6 Printing objects to a real file still wasn't done right: if the
object's type didn't define tp_print, there were still cases where the
full "print uses str() which falls back to repr()" semantics weren't
honored.  This resulted in

    >>> print None
    <None object at 0x80bd674>
    >>> print type(u'')
    <type object at 0x80c0a80>

Fixed this by always using the appropriate PyObject_Repr() or
PyObject_Str() call, rather than trying to emulate what they would do.

Also simplified PyObject_Str() to always fall back on PyObject_Repr()
when tp_str is not defined (rather than making an extra check for
instances with a __str__ method).  And got rid of the special case for
strings.
2001-05-01 16:53:37 +00:00
Guido van Rossum 189f1df301 Add a proper implementation for the tp_str slot (returning self, of
course), so I can get rid of the special case for strings in
PyObject_Str().
2001-05-01 16:51:53 +00:00
Guido van Rossum 09e563abb4 Add experimental iterkeys(), itervalues(), iteritems() to dict
objects.

Tests show that iteritems() is 5-10% faster than iterating over the
dict and extracting the value with dict[key].
2001-05-01 12:10:21 +00:00
Guido van Rossum 82c690f11a Well darnit! The innocuous fix I made to PyObject_Print() caused
printing of instances not to look for __str__().  Fix this.

Tim Peters cab3f68f61 SF bug #417093: Case sensitive import: dir and .py file w/ same name
Directory containing
    Spam.py
    spam/__init__.py
Then "import Spam" caused a SystemError, because code checking for
the existence of "Spam/__init__.py" finds it on a case-insensitive
filesystem, but then bails because the directory it finds it in
doesn't match case, and then old code assumed that was still an error
even though it isn't anymore.  Changed the code to just continue
looking in this case (instead of calling it an error).  So
    import Spam
and
    import spam
both work now.

Tim Peters 748b8bbe02 Fix buglet reported on c.l.py: map(fnc, file.xreadlines()) blows up.
Also a 2.1 bugfix candidate (am I supposed to do something with those?).
Took away map()'s insistence that sequences support __len__, and cleaned
up the convoluted code that made it *look* like it really cared about
__len__ (in fact the old ->len field was only *used* as a flag bit, as
the main loop only looked at its sign bit, setting the field to -1 when
IndexError got raised; renamed the field to ->saw_IndexError instead).

Tim Peters b3d8d1f76c A different approach to the problem reported in
Patch #419651: Metrowerks on Mac adds 0x itself
C std says %#x and %#X conversion of 0 do not add the 0x/0X base marker.
Metrowerks apparently does.  Mark Favas reported the same bug under a
Compaq compiler on Tru64 Unix, but no other libc broken in this respect
is known (known to be OK under MSVC and gcc).
So just try the damn thing at runtime and see what the platform does.
Note that we've always had bugs here, but never knew it before because
a relevant test case didn't exist before 2.1.

Guido van Rossum 3a80c4a29c (Adding this to the trunk as well.)
Fix a very old flaw in PyObject_Print().  Amazing!  When an object
type defines tp_str but not tp_repr, 'print x' to a real file
object would not call the tp_str slot but rather print a default style
representation: <foo object at 0x....>.  This even though 'print x' to
a file-like-object would correctly call the tp_str slot.

Jack Jansen e9bcb5c766 Got rid of the whole event filtering mess again, I can't get it to work. Simply disabling the Tk event handling hook in _tkinter is not as nice, but at least it works. 2001-04-27 20:43:27 +00:00
Jeremy Hylton ddc4fd03b1 Fix 2.1 nested scopes crash reported by Evan Simpson
The new test case demonstrates the bug.  Be more careful in
symtable_resolve_free() to add a var to cells or frees only if it
won't be added under some other rule.

XXX Add new assertion that will catch this bug.

Fred Drake 8f42e2b1fa Update test to accomodate the change to the namespace_separator parameter
of ParserCreate().

Added assignment tests for the ordered_attributes and specified_attributes
values, similar to the checks for the returns_unicode attribute.
2001-04-25 16:03:54 +00:00
Fred Drake cde79131ea ParserCreate(): Allow an empty string for the namespace_separator argument;
while not generally a good idea, this is used by RDF users, and works
    to implement RDF-style namespace+localname concatenation as defined
    in the RDF specifications.  (This also corrects a backwards-compatibility
    bug.)

Be more conservative while clearing out handlers; set the slot in the
self->handlers array to NULL before DECREFing the callback.

Still more adjustments to make the code style internally consistent.

Tim Peters c09cee4d92 SF bug 418615: regular expression bug in pipes.py.
Obviously bad regexps, spotted by Jeffery Collins.

HELP!  I can't run this on Windows, and the module test() function
probably doesn't work on anyone's box.  Could a Unixoid please write
an at least minimal working test and add it to the std test suite?

Marc-André Lemburg 8155e0e541 This patch originated from an idea by Martin v. Loewis who submitted a
patch for sharing single character Unicode objects.

Martin's patch had to be reworked in a number of ways to take Unicode
resizing into consideration as well. Here's what the updated patch
implements:

* Single character Unicode strings in the Latin-1 range are shared
  (not only ASCII chars as in Martin's original patch).

* The ASCII and Latin-1 codecs make use of this optimization,
  providing a noticable speedup for single character strings. Most
  Unicode methods can use the optimization as well (by virtue
  of using PyUnicode_FromUnicode()).

* Some code cleanup was done (replacing memcpy with Py_UNICODE_COPY)

* The PyUnicode_Resize() can now also handle the case of resizing
  unicode_empty which previously resulted in an error.

* Modified the internal API _PyUnicode_Resize() and
  the public PyUnicode_Resize() API to handle references to
  shared objects correctly. The _PyUnicode_Resize() signature
  changed due to this.

* Callers of PyUnicode_FromUnicode() may now only modify the Unicode
  object contents of the returned object in case they called the API
  with NULL as content template.

Note that even though this patch passes the regression tests, there
may still be subtle bugs in the sharing code.

Guido van Rossum 213c7a6aa5 Mondo changes to the iterator stuff, without changing how Python code
sees it (test_iter.py is unchanged).

- Added a tp_iternext slot, which calls the iterator's next() method;
  this is much faster for built-in iterators over built-in types
  such as lists and dicts, speeding up pybench's ForLoop with about
  25% compared to Python 2.1.  (Now there's a good argument for
  iterators. ;-)

- Renamed the built-in sequence iterator SeqIter, affecting the C API
  functions for it.  (This frees up the PyIter prefix for generic
  iterator operations.)

- Added PyIter_Check(obj), which checks that obj's type has a
  tp_iternext slot and that the proper feature flag is set.

- Added PyIter_Next(obj) which calls the tp_iternext slot.  It has a
  somewhat complex return condition due to the need for speed: when it
  returns NULL, it may not have set an exception condition, meaning
  the iterator is exhausted; when the exception StopIteration is set
  (or a derived exception class), it means the same thing; any other
  exception means some other error occurred.
