gh-78469: Declare missing sethostname for Solaris 10 #109447

kulikjak · 2023-09-15T13:03:22Z

As discussed in the issue, sethostname is missing from Solaris 10 headers but is available on Solaris 11.

And because there isn't an OS version specific macro for Solaris, I had to "create" one.

Issue: Declare sethostname in socketmodule.c for SOLARIS #78469

wow, that's very spefic. It was available before and after, but not at version 510? :-)

How do you distinguish Solaris 5.10 and Solaris 51.0?

Maybe multiply the major version by 100 or 1000? or use a shift of 8 bits? The usage would be:

major = VERSION >> 8 minor = VERSION & 255

The disavantage is the need to write versions in hexadecimal :-(

@erlend-aasland: Should we prefix new pyconfig.h constants by Py_ ? see: capi-workgroup/problems#46

I think we should follow the PEP-7 recommendations: https://peps.python.org/pep-0007/#naming-conventions

How do you distinguish Solaris 5.10 and Solaris 51.0?

I see what you mean, but that's not happening. The leading 5 was dropped from the name 25 years ago and while e.g. uname and compilation targets still use it, nobody today calls it Solaris/SunOS 5.10; only Solaris 10. If we ever release Solaris 51, uname -r should report it as 5.51.

That said, I am not strongly against changing it if you still prefer your suggestion.

Thanks, I missed that. It's fixed now.

When was Solaris 10 release? Is it still supported? Does this change better to forks of Solaris?

When was Solaris 10 release? Is it still supported? Does this change better to forks of Solaris?

Sorry for such a long delay. As mentioned in the issue, Solaris 10, while in the "extended support stage" intended mostly for critical fixes, is still supported (ATM at least until January 2025). There are still people using it and possibly installing newer Python onto it.

As for the Solaris forks, this doesn't affect those because the first open version was Solaris 11.

Is this a bug-fix? If so, we should backport it and add a NEWS entry.

vstinner · 2023-10-06T13:50:22Z

@kulikjak Update configure

Do you use "make regen-configure"? See: https://docs.python.org/dev/using/configure.html#generated-files

@kulikjak: Anyway, I push directly into your branch to fix the configure script (regenerate it).

Modules/socketmodule.c

LGTM.

vstinner · 2023-10-06T13:53:29Z

@kulikjak: I also replaced Py_SUNOS_VERSION == 510 with Py_SUNOS_VERSION <= 510.

kulikjak · 2023-10-09T12:13:50Z

Do you use "make regen-configure"? See: https://docs.python.org/dev/using/configure.html#generated-files

Sigh, sorry. Normally, I do, but this time I thought that I could quickly edit it myself, ... and I was wrong. Thanks for fixing it.

Is this a bug-fix? If so, we should backport it and add a NEWS entry.

I guess it is (fixing a build on Solaris <= 10). I can add a NEWS entry, although now there is a skip-news tag, so I am not sure whether I should do so?

Other than that, the build failure doesn't seem to be related, so that's good.
