Martin v. Löwis 849a972f35 Patch #809535: Mention behaviour of seek on text files. Backported to 2.3. 2003-10-18 09:38:01 +00:00
Raymond Hettinger ae4a299a0d Fix typo found by Neal Norwitz. 2003-10-16 17:16:30 +00:00
Raymond Hettinger 42b1ba31af * list.sort() now supports three keyword arguments: cmp, key, and reverse.
key provides C support for the decorate-sort-undecorate pattern.
  reverse provide a stable sort of the list with the comparisions reversed.

* Amended the docs to guarantee sort stability.

Raymond Hettinger 8ae4689657 Simplify and speedup uses of Py_BuildValue():
* Py_BuildValue("(OOO)",a,b,c)  -->  PyTuple_Pack(3,a,b,c)
* Py_BuildValue("()",a)         -->  PyTuple_New(0)
* Py_BuildValue("O", a)         -->  Py_INCREF(a)

Raymond Hettinger cb2da43db8 Extended tuple's C API to include a new function, PyTuple_Pack() that is
useful for rapidly building argument tuples without having to invoke the
more sophisticated machinery of Py_BuildValue().

Jeremy Hylton 504de6bd2c Fix for SF bug [ 817156 ] invalid \U escape gives 0=length unistr. 2003-10-06 05:08:26 +00:00
Tim Peters ced69f8a20 On c.l.py, Martin v. Löwis said that Py_UNICODE could be of a signed type,
so fiddle Jeremy's fix to live with that.  Also added more comments.

Bugfix candidate (this bug is in all versions of Python, at least since
2.1).

Jeremy Hylton d808279be3 Double-fix of crash in Unicode freelist handling.
If a length-1 Unicode string was in the freelist and it was
uninitialized or pointed to a very large (magnitude) negative number,
the check

	 unicode_latin1[unicode->str[0]] == unicode

could cause a segmentation violation, e.g. unicode->str[0] is 0xcbcbcbcb.

Fix this in two ways:

1. Change guard befor unicode_latin1[] to test against 256U.  If I
   understand correctly, the unsigned long used to store UCS4 on my
   box was getting converted to a signed long to compare with the
   signed constant 256.

2. Change _PyUnicode_New() to make sure the first element of str is
   always initialized to zero.  There are several places in the code
   where the caller can exit with an error before initializing any
   of str, which would leave junk in str[0].

Also, silence a compiler warning on pointer vs. int arithmetic.

Bug fix candidate.

Raymond Hettinger a9e14b7015 Fix leak in classobject.c. The leak surfaced on the error exit when
hashing a class that does not define __hash__ but does define a
comparison.
2003-09-16 07:11:46 +00:00
Jeremy Hylton deb2dc6658 Change checks of PyUnicode_Resize() return value for clarity.
The unicode_resize() family only returns -1 or 0 so simply checking
for != 0 is sufficient, but somewhat unclear.  Many Python API
functions return < 0 on error, reserving the right to return 0 or 1 on
success.  Change the call sites for consistency with these calls.

Martin v. Löwis 7bbcde70d1 Only release buffer after file has been closed. Fixes #800824.

Tim Peters f1827cfaab SF bug 801631: file.truncate fault on windows.
file_truncate():  C doesn't define what fflush(fp) does if fp is open
for update, and the preceding I/O operation on fp was input.  On Windows,
fflush() actually changes the current file position then.  Because
Windows doesn't support ftruncate() directly, this not only caused
Python's file.truncate() to change the file position (contra our docs),
it also caused the file not to change size.

Repaired by getting the initial file position at the start, restoring
it at the end, and tossing all the complicated micro-efficiency checks
trying to avoid "provably unnecessary" seeks.  file.truncate() can't
be a frequent operation, and seeking to the current file position has
got to be cheap anyway.

Bugfix candidate.

Michael W. Hudson b2c7de4667 Fix for
[ 784825 ] fix obscure crash in descriptor handling

Should be applied to release23-maint and in all likelyhood
release22-maint, too.

Certainly doesn't apply to release21-maint.

Michael W. Hudson da0a0673b1 My last fix left n used unitialized in tha a==b case.
Fix, by not using n at all in that case.

Needs to be applied to release23-maint, too.

Tim Peters 465fa3dac4 complex_new(): This could leak when the argument was neither string nor
number.  This accounts for the 2 refcount leaks per test_complex run
Michael Hudson discovered (I figured only I would have the stomach to
look for leaks in floating-point code <wink>).
2003-08-15 01:16:37 +00:00
Walter Dörwald e5402fb340 Fix refcount leak in PyUnicode_EncodeCharmap(). The bug surfaces
when an encoding error occurs and the callback name is unknown,
i.e. when the callback has to be called. The problem was that
the fact that the callback has already been looked up was only
recorded in a local variable in charmap_encoding_error(), because
charmap_encoding_error() got it's own copy of the errorHandler
pointer instead of a pointer to the pointer in
PyUnicode_EncodeCharmap().

Michael W. Hudson b4f49385a3 Fix reference leak noted in test_types:
Check for a[:] = a _before_ calling PySequence_Fast on a.
release23-maint candidate
Reference leak doesn't happen with head of release22-maint.
2003-08-14 17:04:28 +00:00
Michael W. Hudson 71665dc90d Add a couple of decrefs to error paths.
Now test_descr only appears to leak two references & I think this
are in fact illusory (it's to do with things getting resurrected in
__del__ methods & it's easy to be believe confusion occurs when that
happens <wink>).  Woohoo!

Michael W. Hudson bdc6ea1110 Fix silly typo in comment. 2003-08-11 16:14:06 +00:00
Michael W. Hudson a6a277d831 /* XXX From here until type is allocated, "return NULL" leaks bases! */
Sure looks like it to me! <wink>

When I run the leak2.py script I posted to python-dev, I only see
three reference leaks in all of test_descr.  When I run
test_descr.test_main, I still see 46 leaks.  This clearly demands
posting a yelp to python-dev :-)

This certainly should be applied to release23-maint, and in all
likelyhood release22-maint as well.

Michael W. Hudson e723e453a1 Repair refcounting on error return from type_set_bases.

Jeremy Hylton 1c7a0ea056 Remove unnecessary check in tests for slots allowed.
The !PyType_Check(base) check snuck in as part of rev 2.215, but was
unrelated to the SF patch that is mentioned in the checkin comment.
The test is currently unnecessary because base is set to the return
value of best_bases(), which returns a type or NULL.

Fred Drake fe89cc186c Remove proxy_print(), since that caused an inconsistency between
"print repr(proxy(a))" and "proxy(a)" at an interactive prompt.

Jeremy Hylton 3e3159ce6a Require that __nonzero__() return a bool or exactly an int. 2003-06-27 17:38:27 +00:00
Jeremy Hylton 090a3495b3 Check return type of __nonzero__() method.
The language reference says you must return an int or a bool.  This
fix limits the scope of SF bug 759227 (infinite recursion) to
subclasses of int.
