Thanks for pointing me to the package. Turns out it was intentional: https://github.com/docker-library/official-images/issues/2863
A caveat to Swift developers using official Docker Ubuntu images in the future.

Maybe it got uninstalled or was never installed as part of the base. An ‘apt-get install tzdata’ might fix it.

Specifically, on a Travis matrix build using Swift 3.1.1 on a Ubuntu 16.04 docker image running inside a Travis 14.04 VM. The issue was specific to the Ubuntu 16.04 docker image; when I tested in Ubuntu 16.04 OS as a guest VM, the issue went away.

Maybe the best solution for now is to find a good mechanism to check the underlying version of the OS and split it out into a function as you suggest. - Tony On Jul 6, 2017, at 7:37 AM, Ian Partridge via swift-corelibs-dev < [email protected] > wrote: Good shout Simon, you are right. I'm on Sierra. Compare and contrast: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/tzfile.h #define TZDIR "/usr/share/zoneinfo" /Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/tzfile.h #define TZDIR "/var/db/timezone/zoneinfo" so I guess if I installed the High Sierra beta it would work OK. I hacked CF to force it to use /usr/share/zoneinfo and TestFoundation is much happier, but that's not a solution. On 6 July 2017 at 15:20, Simon Evans < [email protected]> wrote: Ian I also saw this error, I think its because the TZDIR is different in the headers shipped with Xcode 9. Maybe the location of the timezone directory was moved between Sierra and High Sierra. What version of macOS are you testing on? If it has indeed moved between 10.12 and 10.13 it may require a runtime version check to dynamically return TZDIR. Simon On 6 Jul 2017, at 15:09, Ian Partridge via swift-corelibs-dev <[email protected] > wrote: Hi, I'm seeing quite a lot of tests failing when running the TestFoundation target in Xcode. The failures are timezone related. Most simply, the code let timeZone = TimeZone(abbreviation: "GMT") is returning nil. Walking through the CF code which sets things up, it seems to be trying to read the timezone database from /var/db/timezone/zoneinfo/zone.tab which doesn't exist on my macOS system. /usr/share/zoneinfo/zone.tab is there and seems to be the right location (?), but CF is picking up TZDIR from tzfile.h which says: #define TZDIR "/var/db/timezone/zoneinfo" Any thoughts? I feel like I'm missing something obvious and have gone too far down the rabbit hole. -- Ian Partridge _______________________________________________ swift-corelibs-dev mailing list [email protected] https://lists.swift.org/mailman/listinfo/swift-corelibs-dev -- Ian Partridge _______________________________________________ swift-corelibs-dev mailing list [email protected] https://lists.swift.org/mailman/listinfo/swift-corelibs-dev _______________________________________________ swift-corelibs-dev mailing list [email protected] https://lists.swift.org/mailman/listinfo/swift-corelibs-dev _______________________________________________ swift-corelibs-dev mailing list [email protected] https://lists.swift.org/mailman/listinfo/swift-corelibs-dev _______________________________________________ swift-corelibs-dev mailing list [email protected] https://lists.swift.org/mailman/listinfo/swift-corelibs-dev
