* cal: simplify leap year ruleKarel Zak2017-11-131-5/+1Star
| | | | | | | | | | | | Gregorian rule for leap years has been adopted by reformation in year 1782 (Calendar Act 1750), but all tools (date, SQL servers, etc. etc.) don't care about it and apply the new rule for all year -- including years before the reformation. It's better to be compatible with another tools than try to be perfect :-) Addresses: https://bugzilla.redhat.com/show_bug.cgi?id=1507271 Signed-off-by: Karel Zak <kzak@redhat.com>
* lib/timeutils: add common ISO timestamp masksJ William Piggott2017-11-101-9/+3Star
| | | | | | | | | | | | | | | | | | | | | | * Start the ISO format flags at bit 0 instead of bit 1. * Remove unnecessary _8601 from ISO format flag names to avoid line wrapping and to ease readability. * ISO timestamps have date-time-timzone in common, so move the TIMEZONE flag to bit 2 causing all timestamp masks to have the first three bits set and the last four bits as timestamp 'options'. * Change the 'SPACE' flag to a 'T' flag, because it makes the code and comments more concise. * Add common ISO timestamp masks. * Implement the ISO timestamp masks in all applicable code using the strxxx_iso() functions.

* logger: reconnect on failed send()Karel Zak2017-10-101-9/+38
| | | | | | | | | | | | | | | | | | | The libc syslog() reconnects on failed send(). We need the same thing as logger(1) is expected as long time running tool. For example recommended Apache configuration is: ErrorLog "| /usr/bin/logger -t apache_error -p local6.debug" The issue is that connection endpoint (e.g. syslogd) maybe restarted. The simple way how to test is: for i in $(seq 0 3600); do echo "This is message number $i"; sleep 1; done | logger --tcp --server 127.0.0.1 --port 514 and restart your syslog. The current implementation gets SIGPIPE or write warning message, but it never reconnect. Addresses: https://github.com/karelzak/util-linux/issues/363 Signed-off-by: Karel Zak <kzak@redhat.com>

* build: use --runstatedir instead of --localstatedirAndreas Henriksson2017-07-314-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The util-linux code was previously aligned to use @localstatedir@ and the util-linux build system was set to override the default to use /run. Current GNU Coding Standards introduced the @runstatedir@ variable for this purpose. Lets use that instead. The GNU default for @runstatedir@ is ${localstatedir}/run so util-linux still override the default to be /run to preserve the status quo from before. The only difference is that you'll now pass --runstatedir to override the location on the command line instead of --localstatedir. (FWIW, Debhelper in compat 11 will automatically start passing --runstatedir=/run to all autotools configured builds. It already passes --localstatedir=/var (to avoid it ending up with the GNU default /usr/local/var) which breaks the util-linux build system code that tries to default it to /run. This change will thus allow util-linux and debhelper to work better together and avoid the need for a package-specific override.) Relevant historic commits: * commit 07a16b9d1e5a48550a0d19abb9a900853433ffa2 "build-sys: change --localstatedir to /run" * commit 80c51185d50f00a2701f9379f10fc48a0f885dfc "uuidd: use run configured state directory" * commit 01c5b787947aeaffc7e56000827e3edefa357c59 "agetty: use configured run state directory" [kzak@redhat.com: - add $runstatedir fallback for autoconf < 2.70 - check for unmodified $localstatedir] CC: Sami Kerola <kerolasa@iki.fi> Signed-off-by: Andreas Henriksson <andreas@fatal.se> Signed-off-by: Karel Zak <kzak@redhat.com>
