STINNER Victor added the comment: > In any case, I think the namedtuple / structseq solution is elegant, because > we can add additional information later I used the same design for the new sys.unraisablehook in bpo-36829 and I'm already working on adding a new 'err_msg' field to the

[issue37040] checking for membership in itertools.count enters infinite loop with no way to exit

Serhiy Storchaka added the comment: Adding the __contains__() method to the count iterator would not solve the general problem with infinite iterators. For example with the following expressions: -1 in filter(None, itertools.count()) -1 in map(float, itertools.count()) It is not

Terry J. Reedy added the comment: Andre Roberge reported on idle-dev that Restore Height has no effect for him with Python 3.7.3, 32 bit, on Windows 10. Since it works for me on Win 10, 3.7.3-32 bit local debug build and 3.7.3-64 bit installed and ditto for 3.8, I am initially baffled.

[issue1230540] sys.excepthook doesn't work in threads

Antoine Pitrou added the comment: A Thread.excepthook() method does not allow to notify exceptions raised in C-created threads ("dummy threads"). Also, as I said already, you can get the current thread by calling threading.current_thread() in the except hook. There is no need to pass it

[issue27987] obmalloc's 8-byte alignment causes undefined behavior

Antoine Pitrou added the comment: Here is what I've found for (32-bit) ARM: - "long double" is 8 bytes long, so it's probably the same as "double" (see http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dai0274b/index.html) - the standard alignment for "double" is 8 bytes (see
