All autopkgtests for the newly accepted tzdata (2024a-3ubuntu1) for noble have finished running. The following regressions have been reported in tests triggered by the package:
chrony/unknown (ppc64el) golang-github-lib-pq/1.10.9-2 (amd64, arm64) pandas/2.1.4+dfsg-7 (arm64) prometheus-alertmanager/0.26.0+ds-1 (armhf) python-tempora/unknown (ppc64el) reposurgeon/4.38-1 (ppc64el) ruby-tzinfo/unknown (ppc64el) tzdata/2024a-3ubuntu1 (armhf) tzdata/unknown (ppc64el) ubuntu-dev-tools/0.201ubuntu2 (amd64, arm64, armhf, i386, ppc64el, s390x) Please visit the excuses page listed below and investigate the failures, proceeding afterwards as per the StableReleaseUpdates policy regarding autopkgtest regressions [1]. https://people.canonical.com/~ubuntu-archive/proposed- migration/noble/update_excuses.html#tzdata [1] https://wiki.ubuntu.com/StableReleaseUpdates#Autopkgtest_Regressions Thank you! -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to tzdata in Ubuntu. https://bugs.launchpad.net/bugs/2062522 Title: std::chrono::locate_zone("Asia/Chungking") fails Status in glibc package in Ubuntu: New Status in tzdata package in Ubuntu: Fix Committed Status in tzdata source package in Noble: Fix Committed Bug description: [ Impact ] forwarded from https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114770 ``` #include <chrono> int main() { (void) std::chrono::locate_zone("Asia/Chungking"); } ``` With the latest tzdata (version 2024a-2) on Debian Sid this fails: terminate called after throwing an instance of 'std::runtime_error' what(): tzdb: cannot locate zone: Asia/Chungking Aborted (core dumped) The problem is a Debian patch that enables link chaining, so that one link can have another link as its target: https://sources.debian.org/patches/tzdata/2024a-2/ziguard.awk-Move-link-to-link-feature-from-vanguard-to-ma.patch/ This feature was added to tzdata in 2022, but isn't compatible with the expectations of the C++20 standard. When chrono::locate_zone finds a link, it expects its target to be a zone, not another link. [ Test Plan ] 1. Install tzdata-legacy 2. Create `testcase.cpp`: ``` #include <chrono> int main() { (void) std::chrono::locate_zone("Asia/Chungking"); } ``` 3. Compile: `g++ -std=c++20 -o testcase testcase.cpp` 4. Run: `./testcase` The test case should not crash.
