example/constructor-stats.h -- framework for printing and tracking object

instance lifetimes in example/test code.

|
||||
|
||||
This header provides a few useful tools for writing examples or tests that want to check and/or
|
||||
display object instance lifetimes. It requires that you include this header and add the following
|
||||
function calls to constructors:
|
||||
|
||||
class MyClass {
|
||||
MyClass() { ...; print_default_created(this); }
|
||||
~MyClass() { ...; print_destroyed(this); }
|
||||
MyClass(const MyClass &c) { ...; print_copy_created(this); }
|
||||
MyClass(MyClass &&c) { ...; print_move_created(this); }
|
||||
MyClass(int a, int b) { ...; print_created(this, a, b); }
|
||||
MyClass &operator=(const MyClass &c) { ...; print_copy_assigned(this); }
|
||||
MyClass &operator=(MyClass &&c) { ...; print_move_assigned(this); }
|
||||
|
||||
...
|
||||
}
|
||||
|
||||
You can find various examples of these in several of the existing example .cpp files. (Of course
|
||||
you don't need to add any of the above constructors/operators that you don't actually have, except
|
||||
for the destructor).
|
||||
|
||||
Each of these will print an appropriate message such as:
|
||||
|
||||
### MyClass @ 0x2801910 created via default constructor
|
||||
### MyClass @ 0x27fa780 created 100 200
|
||||
### MyClass @ 0x2801910 destroyed
|
||||
### MyClass @ 0x27fa780 destroyed
|
||||
|
||||
You can also include extra arguments (such as the 100, 200 in the output above, coming from the
|
||||
value constructor) for all of the above methods which will be included in the output.
|
||||
|
||||
For testing, each of these also keeps track the created instances and allows you to check how many
|
||||
of the various constructors have been invoked from the Python side via code such as:
|
||||
|
||||
from example import ConstructorStats
|
||||
cstats = ConstructorStats.get(MyClass)
|
||||
print(cstats.alive())
|
||||
print(cstats.default_constructions)
|
||||
|
||||
Note that `.alive()` should usually be the first thing you call as it invokes Python's garbage
|
||||
collector to actually destroy objects that aren't yet referenced.
|
||||
|
||||
For everything except copy and move constructors and destructors, any extra values given to the
|
||||
print_...() function is stored in a class-specific values list which you can retrieve and inspect
|
||||
from the ConstructorStats instance `.values()` method.
|
||||
|
||||
In some cases, when you need to track instances of a C++ class not registered with pybind11, you
|
||||
need to add a function returning the ConstructorStats for the C++ class; this can be done with:
|
||||
|
||||
m.def("get_special_cstats", &ConstructorStats::get<SpecialClass>, py::return_value_policy::reference_internal)
|
||||
|
||||
Finally, you can suppress the output messages, but keep the constructor tracking (for
|
||||
inspection/testing in python) by using the functions with `print_` replaced with `track_` (e.g.
|
||||
`track_copy_created(this)`).
