Make dumbdbm merely "dumb", rather than "terminally broken". Without this

metaclass, reported by Dan Parisien.
Objects that are instances of custom metaclasses, i.e. whose class is
a subclass of 'type', should be pickled the same as new-style classes
(objects whose class is 'type'). This can't be done through a
dispatch table entry, and the __reduce__ trick doesn't work for these,
since it finds the unbound __reduce__ for instances of the class
(inherited from 'object'). So check explicitly using issubclass().
This way, when a socket object is deleted after the socket module has
already been zapped by module shutdown, we don't get annoying warnings
about exceptions in __del__ methods.

If no external zip-utility is found, the archive is created by the

This triggered the above bug - so it's better to create the zip-file
far away in the TMP directory.

can't tickle the bug in newer XEmacsen (just tried w/21.4.5) it's

If it crops up again, I'll report it (again) to the XEmacs crowd.

Rev 1.20 introduced a call to getpeername() in the dispatcher
constructor. This only works for a connected socket. Apparently
earlier versions of the code worked with un-connected sockets, e.g. a
listening socket.
It's not clear that the code is supposed to accept these sockets,
because it sets self.connected = 1 when passed a socket. But it's
also not clear that it should be a fatal error to pass a listening
socket.
The solution, for now, is to put a try/except around the getpeername()
call and continue if it fails. The self.addr attribute is used
primarily (only?) to produce a nice repr for the object, so it hardly
matters. If there is a real error on a connected socket, it's likely
that subsequent calls will fail too.

Using grid methods on ScrolledText widgets does not
work as expected. It either fails to pack a widget, or
can even cause Tk to lock up.
The problem is that the .grid method is being called on
the text widget, not the frame widget. This can lead
to the well-known lockup in Tk when a frame's children
are managed by both the pack and grid managers. Even
if it doesn't lock up, the frame is never placed within
the intended widget.
Program fragment:
>>> import ScrolledText
>>> s = ScrolledText.ScrolledText()
>>> s.grid(row=0, column=0, rowspan=2)
The following patch uses the same hack to copy the
'grid' and 'place' geometry manager methods to the
ScrolledText instance as is already used for the 'pack'
manager.

This adds the module name and a dot in front of the type name in every
type object initializer, except for built-in types (and those that
already had this). Note that it touches lots of Mac modules -- I have
no way to test these but the changes look right. Apologies if they're
not. This also touches the weakref docs, which contains a sample type
object initializer. It also touches the mmap test output, because the
mmap type's repr is included in that output. It touches object.h to
put the correct description in a comment.

Big Hammer to implement -Qnew as PEP 238 says it should work (a global
option affecting all instances of "/").
pydebug.h, main.c, pythonrun.c: define a private _Py_QnewFlag flag, true
iff -Qnew is passed on the command line. This should go away (as the
comments say) when true division becomes The Rule. This is
deliberately not exposed to runtime inspection or modification: it's
a one-way one-shot switch to pretend you're using Python 3.
ceval.c: when _Py_QnewFlag is set, treat BINARY_DIVIDE as
BINARY_TRUE_DIVIDE.
test_{descr, generators, zipfile}.py: fiddle so these pass under
-Qnew too. This was just a matter of s!/!//! in test_generators and
test_zipfile. test_descr was trickier, as testbinop() is passed
assumptions that "/" is the same as calling a "__div__" method; put
a temporary hack there to call "__truediv__" instead when the method
name is "__div__" and 1/2 evaluates to 0.5.
Three standard tests still fail under -Qnew (on Windows; somebody
please try the Linux tests with -Qnew too! Linux runs a whole bunch
of tests Windows doesn't):
test_augassign
test_class
test_coercion
I can't stay awake longer to stare at this (be my guest). Offhand
cures weren't obvious, nor was it even obvious that cures are possible
without major hackery.
Question: when -Qnew is in effect, should calls to __div__ magically
change into calls to __truediv__? See "major hackery" at tail end of
last paragraph <wink>.
It was easier than I thought, assuming that no other things contribute
to the instance size besides slots -- a pretty good bet. With a test
suite, no less!
happy if one could delete the __dict__ attribute of an instance. I
love to make Jim happy, so here goes...
- New-style objects now support deleting their __dict__. This is for
all intents and purposes equivalent to assigning a brand new empty
dictionary, but saves space if the object is not used further.
int_mul(): new and vastly simpler overflow checking. Whether it's
faster or slower will likely vary across platforms, favoring boxes
with fast floating point. OTOH, we no longer have to worry about
people shipping broken LONG_BIT definitions <0.9 wink>.
There's now a new structmember code, T_OBJECT_EX, which is used for
all __slot__ variables (except __weakref__, which has special behavior
anyway). This new code raises AttributeError when the variable is
NULL rather than converting NULL to None.
In goahead(), use a bound version of rawdata.startswith() since we use the
same method all the time and never change the value of rawdata. This can
save a lot of bound method creation.
Rather than tweaking the inheritance of type object slots (which turns
out to be too messy to try), this fix adds a __hash__ to the list and
dict types (the only mutable types I'm aware of) that explicitly
raises an error. This has the advantage that list.__hash__([]) also
raises an error (previously, this would invoke object.__hash__([]),
returning the argument's address); ditto for dict.__hash__.
The disadvantage for this fix is that 3rd party mutable types aren't
automatically fixed. This should be added to the rules for creating
subclassable extension types: if you don't want your object to be
hashable, add a tp_hash function that raises an exception.
Also, it's possible that I've forgotten about other mutable types for
which this should be done.
SF patch #480716 by Greg Chapman fixes the problem that super's
__get__ method always returns an instance of super, even when the
instance whose __get__ method is called is an instance of a subclass
of super.
Other issues fixed:
- super(C, C()).__class__ would return the __class__ attribute of C()
rather than the __class__ attribute of the super object. This is
confusing. To fix this, I decided to change the semantics of super
so that it only applies to code attributes, not to data attributes.
After all, overriding data attributes is not supported anyway.
- While super(C, x) carefully checked that x is an instance of C,
super(C).__get__(x) made no such check, allowing for a loophole.
This is now fixed.
ZipFile.__del__(): call ZipFile.close(), like its docstring says it does.
ZipFile.close(): allow calling more than once (as all file-like objects

More changes to the formatdate epoch test: the Mac epoch is in
localtime, so east of GMT it falls in 1903:-( Changed the test to
obtain the epoch in both local time and GMT, and do the right
thing in the comparisons. As a sanity measure also check that
day/month is Jan 1.
_verify(): Pass in the values of globals insted of eval()ing their
names. The use of eval() was obscure and unnecessary, and the patch
claimed random.py couldn't be used in Jython applets because of it.
- Fix for SF bug #482752: __getstate__ & __setstate__ ignored (by Anon.)
In fact, only __getstate__ isn't recognized. This fixes that.
- Separately, the test for base.__flags__ & _HEAPTYPE raised an
AttributeError exception when a classic class was amongst the
bases. Fixed this with a hasattr() bandaid (classic classes never
qualify as the "hard" base class anyway, which is what the code is
trying to find).

component of gmtime(0). Add clause for Unix epoch and Mac epoch (Tim,
what is Windows epoch?).
Also, get rid of the strptime() test, it was way too problematic given
that strptime() is missing on many platforms and issues with locales.
Instead, simply test that formatdate() gets the numeric timezone
calculation correct for the altzone and timezone.

load_inst(): Implement the security hook that cPickle already had.
When unpickling callables which are not classes, we look to see if the

Otherwise we raise an UnpicklingError.
find_class(): We no longer mask ImportError, KeyError, and
AttributeError by transforming them into SystemError. The latter is

This gives mmap() on Windows the ability to create read-only, write-
through and copy-on-write mmaps. A new keyword argument is introduced
because the mmap() signatures diverged between Windows and Unix, so
while they (now) both support this functionality, there wasn't a way to
spell it in a common way without introducing a new spelling gimmick.
The old spellings are still accepted, so there isn't a backward-
compatibility issue here.

It's hack. We know that errno is set to 0 in this case on Windows, so

rfc822.py. The old rfc822.formatdate() produced date strings using
obsolete syntax. The new version produces the preferred RFC 2822

time properly taken into account.

I haven't tested the fix because the situation is non-trivial to

The basic solution is to get rid of the __current_realm attribute of
authentication handlers. Instead, prevent infinite retries by
checking for the presence of an Authenticate: header in the request

presence of retries.

dictobject.c, new functions PyDict_{Merge,Update}FromSeq2. These are
wholly analogous to PyDict_{Merge,Update}, but process a sequence-of-2-

to change dict.update() to allow a sequence-of-2-seqs argument too.

to "x". Got a better name? "mapping_or_sequence_of_pairs" isn't
attractive, although more so than "mosop" <wink>.

- The long-winded repetitions of "a sequence, a container that supports
iteration, or an iterator object" is getting to be a PITA. Many
months ago I suggested factoring this out into "iterable object",
where the definition of that could include being explicit about
generators too (as is, I'm not sure a reader outside of PythonLabs
could guess that "an iterator object" includes a generator call).
- Please check my curly braces -- I'm going blind <0.9 wink>.
abstract.c, PySequence_Tuple(): When PyObject_GetIter() fails, leave
its error msg alone now (the msg it produces has improved since
PySequence_Tuple was generalized to accept iterable objects, and

have even before PyObject_GetIter grew a better msg).

non-standard but common types. Including Martin's suggestion to add
rejected non-standard types from patch #438790. Specifically,
guess_type(), guess_extension(): Both the functions and the methods
grow an optional "strict" flag, defaulting to true, which determines
whether to recognize non-standard, but commonly found types or not.
Also, I sorted, reformatted, and culled duplicates from the big
types_map dictionary. Note that there are a few non-equivalent
duplicates (e.g. .cdf and .xls) for which the first will just get
thrown away. I didn't remove those though.
Finally, use of the module as a script as grown the -l and -e options
to toggle strictness and to do guess_extension(), respectively.
Doc and unittest updates too.
As the comments in the module implied, pyclbr was easily confused by

Is it really necessary to be more specific than to test for TypeError here,
though?
There really isn't a good reason for instance method objects to have

already does this.

(XXX Should we change the preferred name for putenv to setenv, for

This is a big one, touching lots of files. Some of the platforms
aren't tested yet. Briefly, this changes the return value of the
os/posix functions stat(), fstat(), statvfs(), fstatvfs(), and the
time functions localtime(), gmtime(), and strptime() from tuples into
pseudo-sequences. When accessed as a sequence, they behave exactly as
before. But they also have attributes like st_mtime or tm_year. The
stat return value, moreover, has a few platform-specific attributes
that are not available through the sequence interface (because
everybody expects the sequence to have a fixed length, these couldn't
be added there). If your platform's struct stat doesn't define
st_blksize, st_blocks or st_rdev, they won't be accessible from Python
either.
(Still missing is a documentation update.)
The GUI-mode code to display properties blew up if the property functions
(get, set, etc) weren't simply methods (or functions).
"The problem" here is really that the generic document() method dispatches
to one of .doc{routine, class, module, other}(), but all of those require
a different(!) number of arguments. Thus document isn't general-purpose
at all: you have to know exactly what kind of thing is it you're going
to document first, in order to pass the correct number of arguments to
.document for it to pass on. As an expedient hack, just tacked "*ignored"
on to the end of the formal argument lists for the .docXXX routines so
that .document's caller doesn't have to know in advance which path
.document is going to take.

There are now no known cases where the compiler package computes a
stack depth lower than the one computed by the builtin compiler. (To
achieve this state, we had to fix bugs in both compilers :-).
The chief change is to do the depth calculations with respect to basic
blocks. The stack effect of block is calculated. Then the flow graph
is traversed using breadth-first search to find the max weight path
through the graph.

several opcodes: LOAD_ATTR, CALL_FUNCTION (and friends), MAKE_CLOSURE,

Add an optional argument to a decompression object's decompress()
method. The argument specifies the maximum length of the return
value. If the uncompressed data exceeds this length, the excess data
is stored as the unconsumed_tail attribute. (Not to be confused with
unused_data, which is a separate issue.)

inherit_slots(): tp_as_buffer was getting inherited as if it were a

a result, inheriting from a type that implemented buffer methods was

Try to be systematic about dealing with socket and ssl exceptions in
FakeSocket.makefile(). The previous version of the code caught all
ssl errors and treated them as EOF, even though most of the errors
don't mean EOF.
An SSL error can mean on of three things:
1. The SSL/TLS connection was closed.
2. The operation should be retried.
3. An error occurred.
Also, if a socket error occurred and the error was EINTR, retry the
call. Otherwise, it was a legitimate error and the caller should
receive the exception.

Change vereq(x, y) to use "not x == y" rather than "x != y" -- it
makes a difference is some overloading tests.
Most of this code was old enough to vote. Examples of cleanups:
+ Backslashes were used for line continuation even inside unclosed
bracket structures, from back in the days that was still needed.
+ There was no use of % formats, and e.g. the old fpformat module was
still used to format floats "by hand" in conjunction with rjust().
+ There was even use of a do-nothing .ignore() method to tack on to the
end of a chain of method calls, else way back when Python would print
the non-None result (as it does now in an interactive session -- it
*used* to do that in batch mode too).
+ Perhaps controversial (although I can't imagine why for real <wink>),
used augmented assignment where helpful. Stuff like
self.total_calls = self.total_calls + other.total_calls
is just plain harder to follow than
self.total_calls += other.total_calls
seriously wrong. This started out by just fixing the docs, but then it
occurred to me that the doc confusion propagated into misleading vrbl names
too, so I also renamed those to match reality. As a result, INO the time
computations are much easier to understand now (within the limitations of
vast quantities of 3-character names <wink>).
many types were subclassable but had a xxx_dealloc function that
called PyObject_DEL(self) directly instead of deferring to
self->ob_type->tp_free(self). It is permissible to set tp_free in the
type object directly to _PyObject_Del, for non-GC types, or to
_PyObject_GC_Del, for GC types. Still, PyObject_DEL was a tad faster,
so I'm fearing that our pystone rating is going down again. I'm not
sure if doing something like
void xxx_dealloc(PyObject *self)
{
if (PyXxxCheckExact(self))
PyObject_DEL(self);
else
self->ob_type->tp_free(self);
}
is any faster than always calling the else branch, so I haven't
attempted that -- however those types whose own dealloc is fancier
(int, float, unicode) do use this pattern.
This patch allows ConfigParser.getboolean() to interpret TRUE,
FALSE, YES, NO, ON and OFF instead just '0' and '1'.
While just allowing '0' and '1' sounds more correct users often
demand to use more descriptive directives in configuration
files. Instead of forcing every programmer do brew his own
solution a system should include the batteries for this.
[My modification to the patch is a slight rewording of the docstring
and use of lowercase instead of uppercase templates. The code is
still case sensitive. GvR.]
optional, and default to `localhost' and ports 8025 and 25
respectively.
SMTPChannel.__init__(): Calculate __fqdn using socket.getfqdn()
instead of gethostby*() and friends. This allows us to run this
script even if we don't have access to dns (assuming the localhost is
configured properly).
Also, restore my precious page breaks. Hands off, oh Whitespace
Normalizer!
For a dynamically constructed type object, fill in the tp_doc slot with
a copy of the argument dict's "__doc__" value, provided the latter exists
and is a string.
NOTE: I don't know what to do if it's a Unicode string, so in that case
tp_doc is left NULL (which shows up as Py_None if you do Class.__doc__).
Note that tp_doc holds a char*, not a general PyObject*.
it deals correctly with some anomalous cases; according to this test
suite I've fixed it right.
The anomalous cases had to do with 'exception' events: these aren't
generated when they would be most helpful, and the profiler has to
work hard to recover the right information. The problems occur when C
code (such as hasattr(), which is used as the example here) calls back
into Python code and clears an exception raised by that Python code.
Consider this example:
def foo():
hasattr(obj, "bar")
Where obj is an instance from a class like this:
class C:
def __getattr__(self, name):
raise AttributeError
The profiler sees the following sequence of events:
call (foo)
call (__getattr__)
exception (in __getattr__)
return (from foo)
Previously, the profiler would assume the return event returned from
__getattr__. An if statement checking for this condition and raising
an exception was commented out... This version does the right thing.
test for modifying __getattr__ works, now that slot_tp_getattr_hook
zaps the slot if there's no hook. Added an XXX comment with a ref
back to slot_tp_getattr_hook.
Taught doctest about static methods, class methods, and property docstrings
in new-style classes. As for inspect.py/pydoc.py before it, the new stuff
needed didn't really fit into the old architecture (but was less of a
strain to force-fit here).
New-style class docstrings still aren't found, but that's the subject
of a different bug and I want to fix that right instead of hacking around
it in doctest.
instances).
Also added GC support to various auxiliary types: super, property,
descriptors, wrappers, dictproxy. (Only type objects have a tp_clear
field; the other types are.)
One change was necessary to the GC infrastructure. We have statically
allocated type objects that don't have a GC header (and can't easily
be given one) and heap-allocated type objects that do have a GC
header. Giving these different metatypes would be really ugly: I
tried, and I had to modify pickle.py, cPickle.c, copy.py, add a new
invent a new name for the new metatype and make it a built-in, change
affected tests... In short, a mess. So instead, we add a new type
slot tp_is_gc, which is a simple Boolean function that determines
whether a particular instance has GC headers or not. This slot is
only relevant for types that have the (new) GC flag bit set. If the
tp_is_gc slot is NULL (by far the most common case), all instances of
the type are deemed to have GC headers. This slot is called by the
PyObject_IS_GC() macro (which is only used twice, both times in
gcmodule.c).
I also changed the extern declarations for a bunch of GC-related
functions (_PyObject_GC_Del etc.): these always exist but objimpl.h
only declared them when WITH_CYCLE_GC was defined, but I needed to be
able to reference them without #ifdefs. (When WITH_CYCLE_GC is not
defined, they do the same as their non-GC counterparts anyway.)
- The test for deepcopy() in pickles() was indented wrongly, so it got
run twice (one for binary pickle mode, one for text pickle mode; but
the test doesn't depend on the pickle mode).
- In verbose mode, show which subtest (pickle/cPickle/deepcopy, text/bin).
in run_test() referenced two non-existent variables, and in
non-verbose mode, the tests didn't report the actual number, when it
differed from the expected number. Fixed this.
Also added an extra call to gc.collect() at the start of test_all().
This will be needed when I check in the changes to add GC to new-style
classes.
from Tim Hochberg. Also mucho fiddling to change the way doctest
determines whether a thing is a function, module or class. Under 2.2,
this really requires the functions in inspect.py (e.g., types.ClassType
is close to meaningless now, if not outright misleading).
I modified nntplib so the body method can accept an
optional second parameter pointing to a filehandle or
filename (string). This way, really long body
articles can be stored to disk instead of kept in
memory. The way I made the modification should make
it easy to extend this functionality to other extended
return methods.
This is probably a little bit faster, but mostly is just cleaner code.
The old-style support is still used for Python versions < 2.2 so this
source file can be shared with PyXML.
staticness when __dynamic__ = 1 becomes the default:
- Some classes which are used to test the difference between static
and dynamic.
- Subclasses of complex: complex uses old-style numbers and the slot
wrappers used by dynamic classes only support new-style numbers.
(Ideally, the complex type should be fixed, but that looks like a
labor-intensive job.)
__rop__ now takes precendence over __op__. Those circumstances are:
- Both arguments are new-style classes
- Both arguments are new-style numbers
- Their implementation slots for tp_op differ
- Their types differ
- The right argument's type is a subtype of the left argument's type
Also did this for the ternary operator (pow) -- only the binary case
is dealt with properly though, since __rpow__ is not supported anyway.
depending on the cycle detector code in the library implementation.
This is a *slightly* different patch than SF patch #417795, but takes
the same approach. (This version avoids calling the __len__() method of
the dict in the remove() functions.)
This closes SF patch #417795.
