Tim Peters d92ae840e9 test_saveall(): Another small simplification; plus s/l/L/g.
test_del(), test_del_newclass():  No need to use apply() in these.

Tim Peters a1ad3f08ad And one more simplification to test_saveall(). 2002-08-10 21:32:16 +00:00
Tim Peters 4803c126a6 test_saveall(): Simplified a little, given that we only expect one item
in gc.garbage (so no need to loop looking for it -- it's there or it's
not).

Tim Peters c708c0a8c4 If any trash happened to be sitting around waiting to get collected at
the time it's called, test_saveall() made it look a leak, triggering
bogus warnings from regrtest's -l (findleaks) mode.

Guido van Rossum 4aa21aa5b3 Test finalizers and GC from inside __del__ for new classes. 2002-08-09 17:38:16 +00:00
Barry Warsaw 04f357cffe Get rid of relative imports in all unittests. Now anything that
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".

This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).

Now Tim and Jack can have at it. :)

Tim Peters c62b95e550 test_trashcan() and supporting class Ouch(): Jeremy noted that this test
takes much longer to run in the context of the test suite than when run in
isolation.  That's because it forces a large number of full collections,
which take time proportional to the total number of gc'ed objects in the
whole system.

But since the dangerous implementation trickery that caused this test to
fail in 2.0, 2.1 and 2.2 doesn't exist in 2.3 anymore (the trashcan
mechanism stopped doing evil things when the possibility for compiling
without cyclic gc was taken away), such an expensive test is no longer
justified.  This checkin leaves the test intact, but fiddles the
constants to reduce the runtime by about a factor of 5.

Guido van Rossum 05e01ee114 Add a testcase to ensure that cycles going through the __class__ link
of a new-style instance are detected by the garbage collector.

Bugfix candidate.

Tim Peters d222559cdb New test_traschcan() test in test_gc, which reliably provokes segfaults
under 2.0, 2.1 and 2.2.

Bugfix candidate.

Tim Peters 1ce150c675 Remove obsolete __static__/__dynamic__ distinction. 2001-10-15 22:49:27 +00:00
Guido van Rossum 9475a2310d Enable GC for new-style instances. This touches lots of files, since
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.

Guido van Rossum 048eb75c2d Add Garbage Collection support to new-style classes (not yet to their
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.)

Guido van Rossum c907bd89de The error reporting here was a bit sparse. In verbose mode, the code
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.

Neil Schemenauer 88c761a117 Test GC of frame objects. 2001-07-12 13:25:53 +00:00
Marc-André Lemburg 3661908a6a This patch removes all uses of "assert" in the regression test suite
and replaces them with a new API verify(). As a result the regression
suite will also perform its tests in optimization mode.

Neil Schemenauer faae266e89 - Add test for new SAVEALL debugging flag
- Use exceptions rather than asserts for failing tests.
- Reorganize tests and produce some output if verbose option is set.

Vladimir Marangozov f9d20c3786 Neil Schemenauer: GC enable(), disable(), isenabled() interface.
Small stylistic changes by VM:
- is_enabled() -> isenabled()
- static ... Py_<func> -> static ... gc_<func>
