Martin v. Löwis 28e9ce9df2 Patch #734118: Add {get|set}busywaitinterval. 2003-05-09 08:19:48 +00:00
Tim Peters c4607dadce Leading "C:" no longer hardcoded in the default installation directory.
After removing that, two testers on machines where C: is not the system
drive reported that the installer suggested their system drive instead
of C:, and that's what they wanted it to do.

Raymond Hettinger 686b14d7ad SF bug #730296: Unexpected Changes in list Iterator
Reverted a Py2.3b1 change to iterator in subclasses of list and tuple.
They had been changed to use __getitem__ whenever it had been overriden
in the subclass.

This caused some usabilty and performance problems.  Also, it was
inconsistent with the rest of python where many container methods
access the underlying object directly without first checking for
an overridden getter.  Users needing a change in iterator behavior
should override it directly.

Tim Peters 015dd82136 Somewhere along the way, the softspace attr of file objects became read-
only.  Repaired, and added new tests to test_file.py.

Ken Manheimer 595adce09b Allow for multiple parens around pdb prompt for (new) nested debugging
sessions (and some cosmetic wording changes).

Tim Peters c4e0940042 New generator os.walk() does a bit more than os.path.walk() does, and
seems much easier to use.  Code, docs, NEWS, and additions to test_os.py
(testing this sucker is a bitch!).

Guido van Rossum e7adda9035 Move socket news to 2.3b1 section! And mention has_ipv6. 2003-04-25 05:52:37 +00:00
Guido van Rossum 47dfa4a89a Patch by Jp Calderone:
- The socket module now provides the functions inet_pton and inet_ntop
  for converting between string and packed representation of IP addresses.
  See SF patch #658327.

This still needs a bit of work in the doc area, because it is not
available on all platforms (especially not on Windows).

Marc-André Lemburg 246d847475 New module platform.py, submitted by Marc-Andre Lemburg.
There's no separate documentation for this module yet - apart from the
doc-strings which explain the APIs.

Raymond Hettinger f4cf76dd5e Revert the previous enhancement to the bytecode optimizer.
The additional code complexity and new NOP opcode were not worth it.

Raymond Hettinger 1d87786305 SF patch 557704: netrc module can't handle all passwords
Revised netrc.py to include the additional ascii punctuation
characters.  Omitted the other logic changes.  See
Lib/netrc.py 1.17.

Since this is more of a feature request than a bug,
including in Py2.3 but not recommending for backporting.

Tim Peters 11b2306960 Enable os.fsync() for Windows, mapping it to MS's _commit() there. The
docs here are best-guess:  the MS docs I could find weren't clear, and
some even claimed _commit() has no effect on Win32 systems (which is
easily shown to be false just by trying it).

Alex Martelli a70b19147f Adding new built-in function sum, with docs and tests. 2003-04-22 08:12:33 +00:00
Raymond Hettinger 060641d511 Improved the bytecode optimizer.
* Can now test for basic blocks.
* Optimize inverted comparisions.
* Optimize unary_not followed by a conditional jump.
* Added a new opcode, NOP, to keep code size constant.
* Applied NOP to previous transformations where appropriate.

Note, the NOP would not be necessary if other functions were
added to re-target jump addresses and update the co_lnotab mapping.
That would yield slightly faster and cleaner bytecode at the
expense of optimizer simplicity and of keeping it decoupled
from the line-numbering structure.

Martin v. Löwis 153c9e493e Patch #553171: Add writeback parameter. Also add protocol parameter. 2003-04-19 20:59:03 +00:00
Guido van Rossum aa86e35c52 - bool() called without arguments now returns False rather than
raising an exception.  This is consistent with calling the
  constructors for the other builtin types -- called without argument
  they all return the false value of that type.  (SF patch #724135)
  Thanks to Alex Martelli.

Guido van Rossum a26854095b - Several methods of nntplib.NNTP have grown an optional file argument
which specifies a file where to divert the command's output
  (already supported by the body() method).  (SF patch #720468)
  Thanks to Terry Carroll.

Martin v. Löwis 2548c730c1 Implement IDNA (Internationalized Domain Names in Applications). 2003-04-18 10:39:54 +00:00
Tim Peters 21d7d4d5ca _Py_PrintReferenceAddresses(): also print the type name. In real use
I'm finding some pretty baffling output, like reprs consisting entirely
of three left parens.  At least this will let us know what type the object
is (it's not str -- there's no quote character in the repr).

New tool combinerefs.py, to combine the two output blocks produced via
PYTHONDUMPREFS.

Guido van Rossum cf8d285ba3 Changes in support of PEP 269. 2003-04-17 16:53:26 +00:00
Guido van Rossum c1f6e8cbc1 - The repr() of a weakref object now shows the __name__ attribute of
the referenced object, if it has one.

Also use %p to format pointers consistently, and use <weakproxy ...>
in proxy_repr(), to match the type name.

Walter Dörwald 5688b7ac3e Add two dictionaries to htmlentitydefs: name2codepoint maps
HTML entity names to Unicode codepoints (as integers).
codepoint2name is the reverse mapping. From SF patch #722017.

Guido van Rossum 0fc8f00252 - pythunrun.c, Py_Finalize(): move the call to _Py_PrintReferences()
even farther down, to just before the call to
  _PyObject_DebugMallocStats().  This required the following changes:

- pystate.c, PyThreadState_GetDict(): changed not to raise an
  exception or issue a fatal error when no current thread state is
  available, but simply return NULL without raising an exception
  (ever).

- object.c, Py_ReprEnter(): when PyThreadState_GetDict() returns NULL,
  don't raise an exception but return 0.  This means that when
  printing a container that's recursive, printing will go on and on
  and on.  But that shouldn't happen in the case we care about (see
  first bullet).

- Updated Misc/NEWS and Doc/api/init.tex to reflect changes to
  PyThreadState_GetDict() definition.

Guido van Rossum 8b7a9a38c6 The date class is now properly subclassable. (SF bug #720908)
(This is only the tip of the iceberg; the time and datetime classes
need the same treatment.)
2003-04-14 22:01:58 +00:00
Guido van Rossum 3a3cca5b82 - list.insert(i, x) now interprets negative i as it would be
interpreted by slicing, so negative values count from the end of the
  list.  This was the only place where such an interpretation was not
  placed on a list index.

Guido van Rossum 41c99e7f96 SF patch #720991 by Gary Herron:
A small fix for bug #545855 and Greg Chapman's
addition of op code SRE_OP_MIN_REPEAT_ONE for
eliminating recursion on simple uses of pattern '*?' on a
long string.

Guido van Rossum efbbb1c602 Patch by Chad Netzer (with significant change):
- range() now works even if the arguments are longs with magnitude
  larger than sys.maxint, as long as the total length of the sequence
  fits.  E.g., range(2**100, 2**101, 2**100) is the following list:
  [1267650600228229401496703205376L].  (SF patch #707427.)

Guido van Rossum a12fe4e81f - New function sys.call_tracing() allows pdb to debug code
recursively.
- pdb has a new command, "debug", which lets you step through
  arbitrary code from the debugger's (pdb) prompt.

Tim Peters f6b8045ca5 Reworked has_finalizer() to use the new _PyObject_Lookup() instead
of PyObject_HasAttr(); the former promises never to execute
arbitrary Python code.  Undid many of the changes recently made to
worm around the worst consequences of that PyObject_HasAttr() could
execute arbitrary Python code.

Compatibility is hard to discuss, because the dangerous cases are
so perverse, and much of this appears to rely on implementation
accidents.

To start with, using hasattr() to check for __del__ wasn't only
dangerous, in some cases it was wrong:  if an instance of an old-
style class didn't have "__del__" in its instance dict or in any
base class dict, but a getattr hook said __del__ existed, then
hasattr() said "yes, this object has a __del__".  But
instance_dealloc() ignores the possibility of getattr hooks when
looking for a __del__, so while object.__del__ succeeds, no
__del__ method is called when the object is deleted.  gc was
therefore incorrect in believing that the object had a finalizer.

The new method doesn't suffer that problem (like instance_dealloc(),
_PyObject_Lookup() doesn't believe __del__ exists in that case), but
does suffer a somewhat opposite-- and even more obscure --oddity:
if an instance of an old-style class doesn't have "__del__" in its
instance dict, and a base class does have "__del__" in its dict,
and the first base class with a "__del__" associates it with a
descriptor (an object with a __get__ method), *and* if that
descriptor raises an exception when __get__ is called, then
(a) the current method believes the instance does have a __del__,
but (b) hasattr() does not believe the instance has a __del__.

While these disagree, I believe the new method is "more correct":
because the descriptor *will* be called when the object is
destructed, it can execute arbitrary Python code at the time the
object is destructed, and that's really what gc means by "has a
finalizer":  not specifically a __del__ method, but more generally
the possibility of executing arbitrary Python code at object
destruction time.  Code in a descriptor's __get__() executed at
destruction time can be just as problematic as code in a
__del__() executed then.

So I believe the new method is better on all counts.

Bugfix candidate, but it's unclear to me how all this differs in
the 2.2 branch (e.g., new-style and old-style classes already
took different gc paths in 2.3 before this last round of patches,
but don't in the 2.2 branch).
