Bug ID: 108211
Summary: std::chrono::current_zone() fails if zone only has one
component
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: redi at gcc dot gnu.org
Target Milestone: ---
$ ls -l /etc/localtime
lrwxrwxrwx. 1 root root 25 Mar 15 2017 /etc/localtime ->
../usr/share/zoneinfo/UTC
Libstdc++ incorrectly assumes the local timezone will be "foo/bar" and so it
breaks for "UTC" or any other name without a slash in it.
terminate called after throwing an instance of 'std::runtime_error'
what(): tzdb: cannot determine current zone
This causes:
FAIL: std/time/tzdb/1.cc execution test
FAIL: std/time/zoned_time/custom.cc execution test

--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The obvious solution is to try locate_zone(dir/filename) and if that fails try
locate_zone(filename).

libstdc++: Support single components in name of chrono::current_zone()
[PR108211]
We currently only handle the case where /etc/localtime is a symlink to a
path like ".../Etc/UTC" and fail for ".../UTC". This makes both work.
libstdc++-v3/ChangeLog:
PR libstdc++/108211
* src/c++20/tzdb.cc (chrono::current_zone()): Check for zone
using only last component of the name.
