There really isn't a good reason for instance method objects to have
their own __dict__, __doc__ and __name__ properties that just delegate
the request to the function (callable); the default attribute behavior
already does this.
The test suite had to be fixed because the error changes from
TypeError to AttributeError.
strings, not C strings)
removed USE_PYTHON defines, and related sre.py helpers
skip calling the subx helper if the template is callable.
interestingly enough, this means that
def callback(m):
return literal
result = pattern.sub(callback, string)
is much faster than
result = pattern.sub(literal, string)
removed (conceptually flawed) getliteral helper; the new sub/subn code
uses a faster code path for literal replacement strings, but doesn't
(yet) look for literal patterns.
added STATE_OFFSET macro, and use it to convert state.start/ptr to
char indexes
_handle_multipart(): If there is an epilogue and the epilogue does
not itself start with a newline, add a newline before writing the
epilogue. Closes SF bug #472481.
This adds unsetenv to posix, and uses it in the __delitem__ method of
os.environ.
(XXX Should we change the preferred name for putenv to setenv, for
consistency?)
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.
:-).
Add a test that prevents the __hello__ bytecode from going stale
unnoticed again.
The test also tests the loophole noted in SF bug #404545. This test
will fail right now; I'll check in the fix in a minute.
test_no_semis_header_splitter(): This actually should still split.
test_no_split_long_header(): An example of an unsplittable line.
test_no_semis_header_splitter(): Test for SF bug # 471918, Generator
splitting long headers.
_split_header(): Split on folding whitespace if the attempt to split
on semi-colons failed.
_split_header(): Patch by Matthew Cowles for fixing SF bug # 471918,
Generator splitting long headers.
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.
Had to fix the StackDepthTracker to calculate the right info for
several opcodes: LOAD_ATTR, CALL_FUNCTION (and friends), MAKE_CLOSURE,
and DUP_TOPX.
XXX Still need to handle free variables in MAKE_CLOSURE.
XXX There are still a lot of places where the computed stack depth is
larger than for the builtin compiler. These won't cause the
interpreter to overflow the frame, but they waste space.

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.)
Difference from SF patch: Default value for unconsumed_tail is ""
rather than None. It's simpler if the attribute is always a string.
object.c, PyObject_Str: Don't try to optimize anything except exact
string objects here; in particular, let str subclasses go thru tp_str,
same as non-str objects. This allows overrides of tp_str to take
effect.
stringobject.c:
+ string_print (str's tp_print): If the argument isn't an exact string
object, get one from PyObject_Str.
+ string_str (str's tp_str): Make a genuine-string copy of the object if
it's of a proper str subclass type. str() applied to a str subclass
that doesn't override __str__ ends up here.
test_descr.py: New str_of_str_subclass() test.
changing an application to collect profile data on one part of the
app while still making use of the profiled component, without relying
on side effects.
failobj, and when getting the subtype use 'plain' as the failobj.
text/plain is supposed to be the default if the message contains no
Content-Type: header.
Remove the log file after we are done with it. This should clean up after
the test even on Windows, since the file is now closed before we attempt
removal.
Simply commented it out, and then test_hotshot passes on Windows.
Leaving to Fred to fix "the right way" (it seems to be a feature of
unittest that all unittests try to unlink open files <wink>).
inherit_slots(): tp_as_buffer was getting inherited as if it were a
method pointer, rather than a pointer to a vector of method pointers. As
a result, inheriting from a type that implemented buffer methods was
ineffective, leaving all the tp_as_buffer slots NULL in the subclass.
corresponding to a dispatch slot (e.g. __getitem__ or __add__) is set,
calculate the proper dispatch slot and propagate the change to all
subclasses. Because of multiple inheritance, there's no easy way to
avoid always recursing down the tree of subclasses. Who cares?
(There's more to do, but this works. There's also a test for this now.)
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.
headers. It does not parse the body of the message, instead simply
assigning it as a string to the container's payload. This can be much
faster when you're only interested in a message's header.
value, so the programmer will have to catch OverflowError. I'm not sure
what /F's perspective is on this. Perhaps it should be caught and mapped to
an xmlrpclib-specific exception. None of the other type-specific dump
methods seem to do any exception handling though.
call, or via setting an instance or class vrbl.
Rewrote the calibration docs.
Modern boxes are so friggin' fast, and a profiler event does so much work
anyway, that the cost of looking up an instance vrbl (the bias constant)
per profile event just isn't a big deal.
the problem that slots weren't inherited properly. override_slots()
no longer exists; in its place comes fixup_slot_dispatchers() which
does more and different work and is table-based. (Eventually I want
this table also to replace all the little tab_foo tables.)
Also add a wrapper for __delslice__; this required a change in
test_descrtut.py.
When checking for strings use,
! if isinstance(uri, (types.StringType, types.UnicodeType)):
Also get rid of some dodgy code that tried to guess whether attributes
were callable or not.
without the Py_TPFLAGS_CHECKTYPES flag) in the wrappers. This
required a few changes in test_descr.py to cope with the fact that the
complex type has __int__, __long__ and __float__ methods that always
raise an exception.
