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.

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.

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.

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 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.

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.

float_pow():  Don't let the platform pow() raise -1.0 to an integer power

math.pow() will continue to deliver wrong (but platform-native) results
in such cases.

Tim Peters 3cfe75470d PyType_Ready(): Complain if the type is a base type, and gc'able, and
tp_free is NULL or PyObject_Del at the end.  Because it's a base type
it must call tp_free in its dealloc function, and because it's gc'able
it must not call PyObject_Del.

inherit_slots():  Don't inherit tp_free unless the type and its base
agree about whether they're gc'able.  If the type is gc'able and the
base is not, and the base uses the default PyObject_Del for its
tp_free, give the type PyObject_GC_Del for its tp_free (the appropriate
default for a gc'able type).

cPickle.c:  The Pickler and Unpickler types claim to be base classes
and gc'able, but their dealloc functions didn't call tp_free.
Repaired that.  Also call PyType_Ready() on these typeobjects, so
that the correct (PyObject_GC_Del) default memory-freeing function
gets plugged into these types' tp_free slots.

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 c7bc0b98e7 SF patch 730594: assert from longobject.c, line 1215.
Some version of gcc in the "RTEMS port running on the Coldfire (m5200)
processor" generates bad code for a loop in long_from_binary_base(),
comparing the wrong half of an int to a short.  The patch changes the
decl of the short temp to be an int temp instead.  This "simplifies"
the code enough that gcc no longer blows it.

Raymond Hettinger 9928571f3f SF bug 665835: filter() treatment of str and tuple inconsistent
As a side issue on this bug, it was noted that list and tuple iterators
used macros to directly access containers and would not recognize
__getitem__ overrides.  If the method is overridden, the patch returns
a generic sequence iterator which calls the __getitem__ method; otherwise,
it returns a high custom iterator with direct access to container elements.

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.
2003-04-18 00:45:59 +00:00
Tim Peters 269b2a6797 _Py_PrintReferences(): Changed to print object address at start of each
new line.

New pvt API function _Py_PrintReferenceAddresses():  Prints only the
addresses and refcnts of the live objects.  This is always safe to call,
because it has no dependence on Python's C API.

Py_Finalize():  If envar PYTHONDUMPREFS is set, call (the new)
_Py_PrintReferenceAddresses() right before dumping final pymalloc stats.
We can't print the reprs of the objects here because too much of the
interpreter has been shut down.  You need to correlate the addresses
displayed here with the object reprs printed by the earlier
PYTHONDUMPREFS call to _Py_PrintReferences().

Thomas Heller a4ea603b05 SF # 595026: support for masks in getargs.c.
New functions:
  unsigned long PyInt_AsUnsignedLongMask(PyObject *);
  unsigned PY_LONG_LONG) PyInt_AsUnsignedLongLongMask(PyObject *);
  unsigned long PyLong_AsUnsignedLongMask(PyObject *);
  unsigned PY_LONG_LONG) PyLong_AsUnsignedLongLongMask(PyObject *);

New and changed format codes:

b unsigned char 0..UCHAR_MAX
B unsigned char none **
h unsigned short 0..USHRT_MAX
H unsigned short none **
i int INT_MIN..INT_MAX
I * unsigned int 0..UINT_MAX
l long LONG_MIN..LONG_MAX
k * unsigned long none
L long long LLONG_MIN..LLONG_MAX
K * unsigned long long none

Notes:

* New format codes.

** Changed from previous "range-and-a-half" to "none"; the
range-and-a-half checking wasn't particularly useful.

New test test_getargs2.py, to verify all this.

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.

  placed on a list index.

Jeremy Hylton 400d8ee6fa Make staticmethods and classmethods participate in GC.
If a class was defined inside a function, used a static or class
method, and used super() inside the method body, it would be caught in

object would point to a function object with a closure that referred
to the class.)

Tim Peters 7571a0fbcf Improved new Py_TRACE_REFS gimmicks.
Arranged that all the objects exposed by __builtin__ appear in the list
of all objects.  I basically peed away two days tracking down a mystery
leak in sys.gettotalrefcount() in a ZODB app (== tons of code), because
the object leaking the references didn't appear in the sys.getobjects(0)
list.  The object happened to be False.  Now False is in the list, along
with other popular & previously missing leak candidates (like None).
Alas, we still don't have a choke point covering *all* Python objects,
so the list of all objects may still be incomplete.
2003-03-23 17:52:28 +00:00

Tim Peters 36eb4dfb81 Refactored some of the Py_TRACE_REFS code. New private API function
_Py_AddToAllObjects() that simply inserts an object at the front of
the doubly-linked list of all objects.  Changed PyType_Ready() (the
 closest thing we've got to a choke point for type objects) to call
that.

Tim Peters 3e40c7ff5b Oops! Used a wrong preprocessor symbol. 2003-03-23 03:04:32 +00:00
Tim Peters 78be7993b6 When Py_TRACE_REFS is defined, a list of all live objects is maintained in
a doubly-linked list, exposed by sys.getobjects().  Unfortunately, it's not
really all live objects, and it seems my fate to bump into programs where
sys.gettotalrefcount() keeps going up but where the reference leaks aren't
accounted for by anything in the list of all objects.

This patch helps a little:  if COUNT_ALLOCS is also defined, from now on
type objects will also appear in this list, provided at least one object
of a type has been allocated.

Guido van Rossum 4eadfa2b2e Fix from Greg Chapman from SF bug #695651: a complex subclass
constructor, when passed a single complex argument, returns the
argument unchanged.  This should be done only for the complex base
class; a complex subclass should of course cast the value to the
subclass in this case.

The fix also revealed a segfault in complex_getnewargs(): the argument
for the Py_BuildValue() format code "D" is the *address* of a
Py_complex struct, not the value.  (This corroborated by the API
documentation.)

I expect this needs to be backported to 2.2.3.

Guido van Rossum 8e80a72be4 The recent changes to super(), in particular supercheck(), broke when
using super() for an instance in a metaclass situation.  Because the
class was a metaclass, the instance was a class, and hence the

it so that if this branch doesn't apply, the other branch is still
tried.  All tests pass.

Tim Peters 080c88b912 cPickle.c, load_build(): Taught cPickle how to pick apart
the optional proto 2 slot state.

pickle.py, load_build():  CAUTION:  Noted that cPickle's
load_build and pickle's load_build really don't do the same
things with the state, and didn't before this patch either.
cPickle never tries to do .update(), and has no backoff if
instance.__dict__ can't be retrieved.  There are no tests
that can tell the difference, and part of what cPickle's
load_build() did looked accidental to me, so I don't know
what the true intent is here.

pickletester.py, test_pickle.py:  Got rid of the hack for
exempting cPickle from running some of the proto 2 tests.

dictobject.c, PyDict_Next():  documented intended use.

Guido van Rossum 298e421453 SF patch #685738 by Michael Stone.

2003-02-02 07:51:32 +00:00
Tim Peters ee1a53cbb1 cPickle.c: Full support for the new LONG1 and LONG4. Added comments.
Assorted code cleanups; e.g., sizeof(char) is 1 by definition, so there's
no need to do things like multiply by sizeof(char) in hairy malloc
arguments.  Fixed an undetected-overflow bug in readline_file().

longobject.c:  Fixed a really stupid bug in the new _PyLong_NumBits.

pickle.py:  Fixed stupid bug in save_long():  When proto is 2, it
wrote LONG1 or LONG4, but forgot to return then -- it went on to
append the proto 1 LONG opcode too.
Fixed equally stupid cancelling bugs in load_long1() and
load_long4():  they *returned* the unpickled long instead of pushing
it on the stack.  The return values were ignored.  Tests passed
before only because save_long() pickled the long twice.

Fixed bugs in encode_long().

Noted that decode_long() is quadratic-time despite our hopes,
because long(string, 16) is still quadratic-time in len(string).
It's hex() that's linear-time.  I don't know a way to make decode_long()
linear-time in Python, short of maybe transforming the 256's-complement
bytes into marshal's funky internal format, and letting marshal decode
that.  It would be more valuable to make long(string, 16) linear time.

pickletester.py:  Added a global "protocols" vector so tests can try
all the protocols in a sane way.  Changed test_ints() and test_unicode()
to do so.  Added a new test_long(), but the tail end of it is disabled
because it "takes forever" under pickle.py (but runs very quickly under
cPickle:  cPickle proto 2 for longs is linear-time).

Jeremy Hylton 4f0dcc9a9a Provide __module__ attributes for functions defined in C and Python.
__module__ is the string name of the module the function was defined
in, just like __module__ of classes.  In some cases, particularly for
C functions, the __module__ may be None.

Change PyCFunction_New() from a function to a macro, but keep an
unused copy of the function around so that we don't change the binary
API.

Change pickle's save_global() to use whichmodule() if __module__ is
None, but add the __module__ logic to whichmodule() since it might be
used outside of pickle.
2003-01-31 18:33:18 +00:00
Walter Dörwald 2e0b18af30 Change the treatment of positions returned by PEP293
error handers in the Unicode codecs: Negative
positions are treated as being relative to the end of
the input and out of bounds positions result in an
IndexError.

Also update the PEP and include an explanation of
this in the documentation for codecs.register_error.

Fixes a small bug in iconv_codecs: if the position
from the callback is negative *add* it to the size
instead of substracting it.

From SF patch #677429.
2003-01-31 17:19:08 +00:00
Tim Peters 5b8132ffa3 _PyLong_NumBits(): The definition of this was too specific to the quirky
needs of pickling longs.  Backed off to a definition that's much easier
to understand.  The pickler will have to work a little harder, but other
uses are more likely to be correct <0.5 wink>.

_PyLong_Sign():  New teensy function to characterize a long, as to <0, ==0,
or >0.
2003-01-31 15:52:05 +00:00
Guido van Rossum 5d9113d8be Implement appropriate __getnewargs__ for all immutable subclassable builtin

which suppresses use of the memo.
2003-01-29 17:58:45 +00:00
Tim Peters baefd9e552 Added new private API function _PyLong_NumBits. This will be used at the

the caller has no idea how big an array to allocate, and correct
calculation is a bit subtle).

Raymond Hettinger 0a2f849b79 GvR's idea to use memset() for the most common special case of repeating
a single character.  Shaves another 10% off the running time by avoiding
the lg2(N) loops and cache effects for the other cases.
2003-01-06 22:42:41 +00:00
Raymond Hettinger 698258a199 Optimize string_repeat.
Christian Tismer pointed out the high cost of the loop overhead and
function call overhead for 'c' * n where n is large.  Accordingly,
the new code only makes lg2(n) loops.

Interestingly, 'c' * 1000 * 1000 ran a bit faster with old code.  At some
point, the loop and function call overhead became cheaper than invalidating
the cache with lengthy memcpys.  But for more typical sizes of n, the new
code runs much faster and for larger values of n it runs only a bit slower.

Tim Peters 541ceec3e6 PyCFunction_Call(): Combined two switch cases w/ identical bodies. 2003-01-05 07:22:44 +00:00
Raymond Hettinger bf43f8af35 SF Patch #661440: Refactor and streamline PyCFunction_Call
Refactor code in PyCFunction_Call giving a modest (tiny) speed boost,
a slight improvement in semantics (now detects invalid flag combinations),
and (arguably) improved clarity (making it blindingly clear which flag
combinations are allowed).  All this comes at a cost of a few lines of
code duplication.

* Folded test for METH_KEYWORDS into the switch/case.
* Deferred testing for an empty dictionary until when and where needed.
* Make a similar deferral for filling the "size" variable.
* Inverted the dictionary test so that the common case falls though
  instead of making a jump.

Walter Dörwald 7e5c6a02eb Change issubclass() so that recursive tuples (directly or indirectly
containing class objects) are allowed as the second argument.
This makes issubclass() more similar to isinstance() where recursive
tuples are allowed too.
2002-12-12 19:14:08 +00:00
Walter Dörwald d9a6ad3beb Enhance issubclass() and PyObject_IsSubclass() so that a tuple is
supported as the second argument. This has the same meaning as
for isinstance(), i.e. issubclass(X, (A, B)) is equivalent
to issubclass(X, A) or issubclass(X, B). Compared to isinstance(),
this patch does not search the tuple recursively for classes, i.e.
any entry in the tuple that is not a class, will result in a
TypeError.

This closes SF patch #649608.

Tim Peters 61ce0a9bae slot_tp_hash(): In the normal path, this leaked a reference to the

abuse __new__ can invalidate that assumption.

what if the order disagreement doesn't affect any method lookups?
I don't think I care.
