[issue34410] itertools.tee not thread-safe; can segfault interpreter when wrapped iterator releases GIL
hongweipeng added the comment: Multi-process need uses multiprocessing.Manager to share, the current problem should be tee-objcet thread safety issue.As Xiang Zhang said,`PyIter_Next` in `teedataobject_getitem` releases GIL.So the thread lock is necessary,and only lead iterator uses it when runs `PyIter_Next`.Can anyone help me review it. -- nosy: +hongweipeng ___ Python tracker <https://bugs.python.org/issue34410> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue32291] Value error for string shared memory in multiprocessing
hongweipeng added the comment: I think I know the reason. `c_wchar_p` corresponds to the string pointer `wchar_t *`.It's not a good idea to pass pointers between processes. As quoted from `multiprocessing` docs: Note Although it is possible to store a pointer in shared memory remember that this will refer to a location in the address space of a specific process. However, the pointer is quite likely to be invalid in the context of a second process and trying to dereference the pointer from the second process may cause a crash. https://docs.python.org/3.6/library/multiprocessing.html?#module-multiprocessing.sharedctypes -- ___ Python tracker <https://bugs.python.org/issue32291> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue37935] Improve performance of pathlib.scandir()
hongweipeng added the comment:
Scandir() will be close when it iteration is over.You can see
ScandirIterator_iternext:
```
static PyObject *
ScandirIterator_iternext(ScandirIterator *iterator)
{
while (1) {
...
}
/* Error or no more files */
ScandirIterator_closedir(iterator);
return NULL;
}
```
So, `entries = list(scandir(parent_path))` resources in this code can be
properly closed.

`.` can match any character in regular expression.So I don't think that's a

[issue38105] hash collision when hash(x) == -2 causes many calls to __eq__
hongweipeng added the comment:
More than -2, -1 -4 -8 -16 and -32 will cause many calls to __eq__.In
`set_add_entry` use
```
perturb >>= PERTURB_SHIFT;
i = (i * 5 + 1 + perturb) & mask;
```
get the next index.In the example,mask is 7,perturb is -2. If i = 6, after
execution, the value of i has not changed.We can do one more verification like:
```
do {
perturb >>= PERTURB_SHIFT;
} while (i == ((i * 5 + 1 + perturb) & mask));
i = (i * 5 + 1 + perturb) & mask;
```
Of course this requires tests.

[issue40897] Inheriting from class that defines __new__ causes inspect.signature to always return (*args, **kwargs) for constructor
hongweipeng added the comment: >>> from datetime import timedelta as a >>> from _datetime import timedelta as b >>> a is b True >>> `timedelta` is a C-level class, so inspect.signature(timedelta) is the same with inspect.signature(int). But `signature` allow C-level function such as `inspect.signature(len)`, I think one way to improve is to use the C-level function when the python-level function cannot be found. -- ___ Python tracker <https://bugs.python.org/issue40897> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
