[issue40060] socket.TCP_NOTSENT_LOWAT is missing in official macOS builds

Ronald Oussoren added the comment: The work in #441100 is merged into master and 3.9, including an (experimental) "universal2" build of the latter in 3.9.1rc1 that is build with the latest SDK. I'm therefore closing this issue. -- dependencies: -Support macOS 11 and Apple Silicon

[issue40060] socket.TCP_NOTSENT_LOWAT is missing in official macOS builds

Ronald Oussoren added the comment: The active PR on bpo-41100 will make it possible to build the installer on the latest version of macOS (which will be needed to be able to provide support for "Apple Silicon"). IMHO it is not necessary to remove unavailable constants, on some platforms (in

Ma Lin added the comment: It seems that people usually use the socket module like this, I think it's safe to respect this habit: if hasattr(socket, "FLAG_NAME"): do_something If use PR19402, your program will have problem on the older version system, not only "don't break

[issue40060] socket.TCP_NOTSENT_LOWAT is missing in official macOS builds

Dima Tisnek added the comment: Wow, very curious. Yes, it's very much like `socket.TCP_KEEPCNT` in that respect, though, admittedly I don't have a very old Mac to test this right now. I think there were VMs for that maybe? 樂 I wonder, what failure would be best for a naive code below, a

[issue40060] socket.TCP_NOTSENT_LOWAT is missing in official macOS builds

Ma Lin added the comment: Windows build encountered a similar problem, see issue32394. The solution is to check the runtime system version when importing socket module, if it is an older system, delete the constants. [1] issue32394 has a small script (winsdk_watchdog.py) to help find such

[issue40060] socket.TCP_NOTSENT_LOWAT is missing in official macOS builds

Ronald Oussoren added the comment: I don't like that workaround. I'm also not sure if the value of these constants is the same on macOS and iOS (I do know that some constants higher up in the stack are not the same). This issue is a duplicate of an earlier bug about missing functions that I

[issue40060] socket.TCP_NOTSENT_LOWAT is missing in official macOS builds

Dima Tisnek added the comment: Thank you for the explanation, Ronald. `socket.TCP_NOTSENT_LOWAT` is just a constant though, to be passed to `setsockopt`. What do you think of `ifndef ... define ...` work-around, akin to a few other constants in socket module?

[issue40060] socket.TCP_NOTSENT_LOWAT is missing in official macOS builds

Ronald Oussoren added the comment: AFAIK the macOS builds are still build on the oldest macOS release supported by the installer (that is, a macOS 10.9 system). This means the build won't use macOS APIs introduced in macOS 10.10 or later. It would be nice to build the installer using
