@reckenrode:matrix.orgRandy Eckenrodehttps://github.com/nix-community/home-manager/pull/8031 was merged!00:46:51
@reckenrode:matrix.orgRandy Eckenrode emily, I made the requested changes except for the AvailabilityVersions one. Given the goal of eventually creating an internal SDK, which would include the headers from AvailabilityVersions, I’d rather not hack up system_cmds even more in the meantime. 01:09:16
@emilazy:matrix.orgemilyit makes me a bit uneasy to be generating a bunch of availability headers that aren't necessarily the same ones as the main SDK01:09:45
@emilazy:matrix.orgemily I'm okay just adding the /usr/bin/env fix though 01:09:59
@emilazy:matrix.orgemily I'd rather not use darwin.AvailabilityVersions but it's not a blocker 01:10:20
@emilazy:matrix.orgemily (I think even with an internal SDK we'd just want to do the equivalent #define) 01:10:31
@reckenrode:matrix.orgRandy Eckenrode It generates the headers for ${lib.getVersion apple-sdk}. There shouldn’t be any defines newer than what apple-sdk provides. 01:13:08
@reckenrode:matrix.orgRandy EckenrodeTime to see how extremely broken building the macOS 26 source releases is.01:14:04
@emilazy:matrix.orgemily

they have non-trivial differences

@emilazy:matrix.orgemily er, result there is apple-sdk_14 of course 01:16:57
@reckenrode:matrix.orgRandy Eckenrode The iOS/etc stuff isn’t expected to match due to the way filtering is done. Building source releases for iOS isn’t intended to work. The only thing I really find surprising is that the 14.4 SDK has a __MAC_OS_X_VERSION_MAX_ALLOWED of 14.3 not 14.4. 01:20:28
@emilazy:matrix.orgemily for internal SDK purposes I think #define __SPI_AVAILABLE(...) API_AVAILABLE(__VA_ARGS__) and the same for the other macros are a complete implementation of AvailabilityInternalPrivate.h that doesn't have the weird divergences from the public SDK availability header stuff, but if you don't like just touch "$out/include/AvailabilityInternalPrivate.h" or dropping the include I'm okay with merging it as-is as long as the broken shebang is fixed 01:20:31
@reckenrode:matrix.orgRandy EckenrodeThe broken shebang should be fixed.01:20:47
@reckenrode:matrix.orgRandy Eckenrode I would like to avoid hacking up the private headers stuff any more than I already do. Ideally, we would have functioning availability checks for SPIs. That’s going to be particularly useful for if/when we have only one SDK. 01:22:05
@emilazy:matrix.orgemilyother way around: the SDK has 14.401:23:52
@emilazy:matrix.orgemily but darwin.AvailabilityVersions only generates for 14.3 01:23:59
@emilazy:matrix.orgemily

the include of AvailabilityInternalPrivate.h seems like a non-trivial difference, and relevantly they differ in terms of handling of the __SPI_AVAILABLE stuff…

darwin.AvailabilityVersions also creates an AvailabilityMacros.h that doesn't pull in TargetConditionals.h, while the SDK one does

01:24:06
@reckenrode:matrix.orgRandy Eckenrodeadv_cmds gets rid of colldef. That’s not helpful.01:24:21
@emilazy:matrix.orgemilyanyway, like I said we can have functioning availability checks just by forwarding to the non-private ones (that's what the generated headers do in effect)01:24:26
@reckenrode:matrix.orgRandy EckenrodeAh. That could be a bug in my script changes.01:24:33
@emilazy:matrix.orgemilywithout shadowing all the other availability header stuff from the SDK01:24:36
@emilazy:matrix.orgemily this is on nixpkgs-unstable, I could check your PR though 01:24:47
@emilazy:matrix.orgemilyI'm just saying there are a fair few differences01:24:57
@emilazy:matrix.orgemily AFAICT, the __SPI_AVAILABLE stuff is just identical to __API_AVAILABLE for internal stuff and defined away for external stuff 01:25:44
@emilazy:matrix.orgemilynot sure why they do it in such a convoluted way given that but I guess it's what their scripts make convenient01:25:58
@emilazy:matrix.orgemilyalso not sure why they define away the availability for internal stuff01:26:17
@emilazy:matrix.orgemily* also not sure why they define away the availability for external stuff01:26:19
@emilazy:matrix.orgemilynot like it hides the definitions01:26:23
@reckenrode:matrix.orgRandy Eckenrodehttps://github.com/freebsd/freebsd-src/commit/c844ab67178719d956f1571f70bae84edc49cf7201:29:08
@reckenrode:matrix.orgRandy EckenrodeI guess Apple is catching up changes from FreeBSD 11 ….01:29:15
