From: "adi at hexapodia dot org" <sourceware-bugzilla@sourceware.org> To: glibc-bugs@sources.redhat.com Subject: [Bug libc/5186] New: localtime does not handle changed /etc/localtime Date: Tue, 16 Oct 2007 07:02:00 -0000 [thread overview] Message-ID: <20071016070225.5186.adi@hexapodia.org> (raw) Running "2.3.6.ds1-8" from Debian unstable on x86_64, libc does not seem to correctly update its idea of localtime when /etc/localtime changes. adi@xxxxx:~/tmp$ cat localtime-relink.c #include <time.h> #include <stdio.h> #include <stdlib.h> int main(void) { char b1[40], b2[40]; time_t t; struct tm tm1, tm2; system("ln -snf /usr/share/zoneinfo/PST8PDT /etc/localtime"); system("ls -l /etc/localtime"); t = 1192516347; strftime(b1, sizeof(b1), "%F %T %Z", localtime_r(&t, &tm1)); system("ln -snf /usr/share/zoneinfo/EST5EDT /etc/localtime"); system("ls -l /etc/localtime"); t = 1192516347; strftime(b2, sizeof(b2), "%F %T %Z", localtime_r(&t, &tm2)); printf("b1 = %s\n", b1); printf("b2 = %s\n", b2); return 0; } adi@xxxxx:~/tmp$ cc -Wall -g localtime-relink.c adi@xxxxx:~/tmp$ sudo ./a.out lrwxrwxrwx 1 root root 27 2007-10-15 23:56 /etc/localtime -> /usr/share/zoneinfo/PST8PDT lrwxrwxrwx 1 root root 27 2007-10-16 02:56 /etc/localtime -> /usr/share/zoneinfo/EST5EDT b1 = 2007-10-15 23:32:27 PDT b2 = 2007-10-15 23:32:27 PDT Note that the ls output does have the proper timezone offset, but the two calls to localtime_r return the same 'struct tm' values. Inspecting with gdb shows that all fields are the same. -- Summary: localtime does not handle changed /etc/localtime Product: glibc Version: 2.3.6 Status: NEW Severity: normal Priority: P2 Component: libc AssignedTo: drepper at redhat dot com ReportedBy: adi at hexapodia dot org CC: glibc-bugs at sources dot redhat dot com http://sourceware.org/bugzilla/show_bug.cgi?id=5186 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
