Verification failed. The C++ code seems to read /usr/share/zoneinfo/tzdata.zi which still has the wrong link:
``` $ dpkg -s tzdata | grep ^Version Version: 2024a-3ubuntu1 $ grep Asia/Chungking /usr/share/zoneinfo/tzdata.zi L Asia/Chongqing Asia/Chungking $ ls -l /usr/share/zoneinfo/Asia/Chungking lrwxrwxrwx 1 root root 8 Apr 19 19:51 /usr/share/zoneinfo/Asia/Chungking -> Shanghai ``` -- 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.
