[issue47067] Add vectorcall for generica alias object
penguin_wwy <940375...@qq.com> added the comment: > You could also try replacing PyObject_SetAttrString with PyObject_SetAttr and > adding "__orig_class__" to the global strings with > Tools/scripts/generate_global_objects.py, probably for a later PR. Already done via `make regen-global-objects` Also, I found that `regen-global-objects` depends on `regen-deepfreeze`, which should be a bug. This causes the `regen-global-objects` to be executed with the compile task first, and it does not compile successfully at this point because of the new symbols(_Py_ID(__orig_class__)) added. -- ___ Python tracker <https://bugs.python.org/issue47067> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue47067] Add vectorcall for generica alias object
penguin_wwy <940375...@qq.com> added the comment: The point of bpo-40369 issue seems to be to provide vectorcall to the `GenericAliasType`, means vectorcall for `Queue[int]` However, my idea is to add vectorcall to gaobject, like this: ``` d = dict[int] d(a=1, b=2) <-- vectorcall ``` The idea came from my desire to implement different subclasses of a type when implementing some kind of factory model： ``` class ChildClassBuilder: ... def set_type(self, t: Type): self.t = t def build(): instance = self.t() ... return instance ``` In the case of high type-hint coverage, the `self.t` is often a gaobject. Benchmark example： ``` def test(): d = dict[int] for _ in range(100): d(a=1, b=2) ``` Speedup 20% in my wsl2 ``` opt: ncalls tottime percall cumtime percall filename:lineno(function) 10.0000.0001.7281.728 :1() 11.7281.7281.7281.728 test.py:4(test) master: ncalls tottime percall cumtime percall filename:lineno(function) 10.0000.0002.2712.271 :1() 12.2712.2712.2712.271 test.py:4(test) ``` -- ___ Python tracker <https://bugs.python.org/issue47067> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue47067] Add vectorcall for generica alias object
New submission from penguin_wwy <940375...@qq.com>: Although `ga_call` determines whether `origin` has a vectorcall, it needs to be unpacked the parameters that are already packed. /-> origin.vectorcall(unpacked) MakeTpCall(packed) -> ga_call -> PyObject_Call \-> origin.tp_call We can advance the `vectorcall` judgment to the `setup` phase. ga_vectorcall -> origin.vectorcall or ga_make_tp_call -> _PyObject_MakeTpCall(packed argument) -> origin.tp_call This will have no effect on tp_call, which still only needs to be packed once, while vectorcall does not need packed/unpacked -- components: Library (Lib) messages: 415556 nosy: penguin_wwy priority: normal severity: normal status: open title: Add vectorcall for generica alias object versions: Python 3.11 ___ Python tracker <https://bugs.python.org/issue47067> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue46813] Allow developer to resize the dictionary
penguin_wwy <940375...@qq.com> added the comment: I tried to look for it in issue list two days ago but couldn't find it. Maybe I should have been more careful :(. However, I think it is a useful modification. Just need to return a dict that satisfies the user's requirements, and the developers themselves should be responsible for their code (if they can't use it exactly, they should choose to use the default, and python needs to do is provide that optional ability) -- ___ Python tracker <https://bugs.python.org/issue46813> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue45928] Set up file stream for redirecting GC logs
penguin_wwy <940375...@qq.com> added the comment: Thank you for the reminder. At first, I wanted to analyze the effectiveness of GC through logs. However, because GC through the stderr output, these logs are mixed in with other output(such as warnings). This make it difficult to handle them automaticaly. So, i added an `TestIOWrapper` parameter(Not just file streams, but also other io, sockets, buffer and so on) to `set_debug` function in gcmodule.c, to redirect GC logs. I think this will help developers monitor the GC more easily, for example when they deal with a memory leak. Of course, the default will remain the same as the previous behavior , log via stderr :) -- ___ Python tracker <https://bugs.python.org/issue45928> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
