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.
using the same algorithm as the slot updates. The slotdefs array is
now sorted by slot offset and has an interned string object corresponding
to the name added to each item. More can be done but I need to commit
this first as a working intermediate stage.
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>).
This patch changes to logic to:
if env.var. set and non-empty:
if env.var. is an integer:
set flag to that integer
if flag is zero: # [actually, <= 0 --GvR]
set flag to 1
Under this patch, anyone currently using
PYTHONVERBOSE=yes will get the same output as before.
PYTHONVERBNOSE=2 will generate more verbosity than
before.
The only unusual case that the following three are
still all equivalent:
PYTHONVERBOSE=yespleas
PYTHONVERBOSE=1
PYTHONVERBOSE=0
This patch updates Python/thread_pthread.h to mask all
signals for any thread created. This will keep all
signals masked for any thread that isn't the initial
thread. For Solaris and Linux, the two platforms I was
able to test it on, it solves bug #465673 (pthreads
need signal protection) and probably will solve bug
#219772 (Interactive InterPreter+ Thread -> core dump
at exit).
I'd be great if this could get some testing on other
platforms, especially HP-UX pre 11.00 and post 11.00,
as I had to make some guesses for the DCE thread case.
AIX is also a concern as I saw some mention of using
sigthreadmask() as a pthread_sigmask() equivalent, but
this patch doesn't use sigthreadmask(). I don't have
access to AIX.
The problem is that if fread() returns a short count, we attempt
another fread() the next time through the loop, and apparently glibc
clears or ignores the eof condition so the second fread() requires
another ^D to make it see the eof condition.
According to the man page (and the C std, I hope) fread() can only
return a short count on error or eof. I'm using that in the band-aid
solution to avoid calling fread() a second time after a short read.
Note that xreadlines() still has this problem: it calls
readlines(sizehint) until it gets a zero-length return. Since
xreadlines() is mostly used for reading real files, I won't worry
about this until we get a bug report.
has grown beyond what font-lock will work with using the default (X)Emacs
settings.
Indentation of the description has been made consistent, and a number of
smaller markup adjustments have been made as well.
a misunderstanding of the refcont behavior of the 'O' format code in
PyArg_ParseTuple() and Py_BuildValue(), respectively.
- pobj is only a borrowed reference, so should *not* be DECREF'ed at
the end. This was the cause of SF bug #470635.
- The Py_BuildValue() call would leak the object produced by
makesockaddr(). (I found this by eyeballing the code.)
Add a fast_container member to Picklerobject. If fast is true, then
fast_container counts the depth of nested container calls. If the
depth exceeds FAST_LIMIT (2000), the fast flag is ignored and the
normal checks occur. This approach is much like the approach for
prevent stack overflow for comparison and reprs of recursive objects
(e.g. [[...]]).
- Fast container used for save_list(), save_dict(), and
save_inst().
XXX Not clear which other save_xxx() functions should use it.
Make Picklerobject into new-style types, using PyObject_GenericGetAttr()
and PyObject_GenericSetAttr().
- Use PyMemberDef for binary and fast members
- Use PyGetSetDef for persistent_id, inst_persistent_id, memo, and
PicklingError.
XXX Not all of these seem like they need to use getset, but it's
not clear why the old getattr() and setattr() had such odd
semantics. One change is that the getvalue() attribute will
exist on all Picklers, not just list-based picklers; I think
this is a more rationale interface.
There is a long laundry list of other changes:
- Remove unused #defines for PyList_SET_ITEM() etc.
- Make some of the indentation consistent
- Replace uses of cPickle_PyMapping_HasKey() where the first
argument is self->memo with calls to PyDict_GetItem(), because
self->memo must be a dictionary.
- Don't bother to check if cPickle_PyMapping_HasKey() returns < 0,
because it can only return 0 or 1.
- Replace uses of PyObject_CallObject() with PyObject_Call(), when
we can guarantee that the argument tuple is really a tuple.
Performance impacts of these changes:
- 5% speedup for normal pickling
- No change to fast-mode pickling.
XXX Really need tests for all the features in cPickle that aren't in
pickle.
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.)
