as diagnosed by Nick Coghlan.
test_capi.py: A test module should never spawn a thread as
a side effect of being imported. Because this one did, the
segfault one of its thread tests caused didn't occur until
a few tests after test_regrtest.py thought test_capi was
finished. Repair that. Also join() the thread spawned
at the end, so that test_capi is truly finished when
regrtest reports that it's done.
_testcapimodule.c test_thread_state(): this spawns a
couple of non-threading.py threads, passing them a PyObject*
argument, but did nothing to ensure that those threads
finished before returning. As a result, the PyObject*
_could_ (although this was unlikely) get decref'ed out of
existence before the threads got around to using it.
Added explicit synchronization (via a Python mutex) so
that test_thread_state can reliably wait for its spawned
threads to finish.
* UINT_MAX -> ULONG_MAX since we are dealing with longs
* ParseTuple needs &int for 'i' and &long for 'l'
There may be a better way to do this, but this works.
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.
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.
start for the C implemention of new pickle LONG1 and LONG4 opcodes (the
linear-time way to pickle a long is to call _PyLong_AsByteArray, but
the caller has no idea how big an array to allocate, and correct
calculation is a bit subtle).
Generalize PyLong_AsLongLong to accept int arguments too. The real point
is so that PyArg_ParseTuple's 'L' code does too. That code was
undocumented (AFAICT), so documented it.
Add raise_exception() to the _testcapi module. It isn't a test, but
the C API exists only to support test_exceptions. raise_exception()
takes two arguments -- an exception class and an integer specifying
how many arguments it should be called with.
test_exceptions uses BadException() to test the interpreter's behavior
when there is a problem instantiating the exception. test_capi1()
calls it with too many arguments. test_capi2() causes an exception to
be raised in the Python code of the constructor.
the new PyLong_{As,From}{Unsigned,}LongLong tests, so the bulk of the
code is in the new #include file testcapi_long.h, which generates
different code depending on how macros are set. This sucks, but I couldn't
think of anything that sucked less.
UNIX headache? If we still maintain dependencies by hand, someone who
knows what they're doing should teach whatever needs it that
_testcapimodule.c includes testcapi_long.h.
Replaced PyLong_{As,From}{Unsigned,}LongLong guts with calls
to _PyLong_{As,From}ByteArray.
_testcapimodule.c:
Added strong tests of PyLong_{As,From}{Unsigned,}LongLong.
Fixes SF bug #432552 PyLong_AsLongLong() problems.
Possible bugfix candidate, but the fix relies on code added to longobject
to support the new q/Q structmodule format codes.
functions. I intend to replace their guts with calls to the new
_PyLong_{As,From}ByteArray() functions, but AFAICT there's no tests for
them at all now; I also suspect PyLong_AsLongLong() isn't catching all
overflow cases, but without a std test to demonstrate that why should you
believe me <wink>.
Also added a raiseTestError() utility function.
(with modification of existing dict elements!).
This is part of SF patch #409864: lazy fix for Pings bizarre scoping
crash.
The adaptation I made to Michael's patch was to change the error
handling to avoid masking other errors (moving the specific error
message to inside test_dict_inner()), and to insert a test for
dict==NULL at the start.
_testcapimodule.c
make sure PyList_Reverse doesn't blow up again
getargs.c
assert args isn't NULL at the top of vgetargs1 instead of
waiting for a NULL-pointer dereference at the end
