* asia (Jordan, Asia/Amman): Jordan switches back to standard time
on 2013-12-20. (Thanks to Steffen Thorsen.) Assume this is at
00:00s, and that the previous schedule resumes next year.
* NEWS: Document this.
The current tzdata now goes to 17, which is uncomfortably close to
the NOSOLAR limit of 20.
* Makefile (CFLAGS): Remove NOSOLAR comment.
* tzfile.h (TZ_MAX_TYPES): Ignore NOSOLAR; always default to 256.
* NEWS: Document this.
(Thanks to Even Scharning for the heads-up.)
* africa (Libya): DST rules are for 2013 only.
(Africa/Tripoli): Switch to EET without DST as of 02:00 today.
* NEWS: Document this.
Problem reported by Patrick 'P. J.' McDermott in
<http://mm.icann.org/pipermail/tz/2013-October/020441.html>.
This code is quite a bit different from what he proposed.
* tzselect.ksh: Rewrite so that it should work with /bin/sh on
common platforms. For portability to Solaris 9 /bin/sh, use
`...`, not $(...), and avoid $((...)).
(doselect): New function. Use this instead of plain 'select'.
Callers no longer need to worry whether it sets the var to empty.
* Makefile, NEWS: Document this.
* zic.c (outzone): Restore diagnostic that was inadvertently
suppressed by the 2013-09-08 change to the 400-years-hack.
This doesn't affect zic's binary output; it affects only the
diagnostics generated by 'zic -v'. The problem evinced itself
with Asia/Tehran, which currently should generate a diagnostic,
but doesn't without this patch.
* NEWS: Document the above.
MinGW problem reported by Theo Veenker in
<http://mm.icann.org/pipermail/tz/2013-September/020378.html>.
The patched code should work even on POSIXish hosts
where 'link' and 'symlink' fail for whatever reason,
e.g., if the destination file system is VFAT.
Also, the patch fixes some bugs when symlinks are used.
* Makefile (CFLAGS): Mention HAVE_LINK in the comment.
(TZDSRCS): Add asctime.o, since MinGW lacks asctime.
(TZDOBJS): Add asctime.c.
* private.h (HAVE_LINK): Default to 1.
* zic.c (link) [!HAVE_LINK]: New macro.
(symlink) [!HAVE_SYMLINK]: New macro.
(dolink): Fix some bugs when 'link' fails but 'symlink' succeeds.
Fall back on copying when both fail.
* NEWS: Document the above.
Problem with leapseconds reported by Matt Burgess in
<http://mm.icann.org/pipermail/tz/2013-September/020379.html>
with a followup by Ian Abbott in
<http://mm.icann.org/pipermail/tz/2013-September/020383.html>.
* Makefile (MANTXTS): New macro.
(maintainer-clean): Use it.
(DOCS): Add it.
(DATA): Add 'leapseconds'.
(LEAP_DEPS): New macro.
(leapseconds): Use it.
(public): Don't depend on set-timestamps; each tarball does that
individually now, to allow for more parallelization.
(date.1.txt, newctime.3.txt, newstrftime.3.txt, newtzset.3.txt)
(time2posix.3.txt, tzfile.5.txt, tzselect.8.txt, zdump.8.txt)
(zic.8.txt): Depend on the corresponding non-.txt file.
$(MANTXTS): New rule.
(set-timestamps.out): Rename from set-timestamps, and make it a file,
so that it has its own timestamp; this avoids useless rework.
Depend on $(ENCHILADA) and ignore files under Git that are not
also listed in $(ENCHILADA). Set the timestamp of 'leapseconds'
and each $(MANTXTS) to be the maximum of its dependencies, to avoid
timestamp churn in future tarballs. Prefer touch -m, as we don't
care about access time here.
(tzcode$(VERSION).tar.gz, tzdata$(VERSION).tar.gz):
Depend on set-timestamps.out rather than the individual files,
so timestamps are set before creating the tarballs even when
make is parallelized.
(tzcode$(VERSION).tar.gz): Don't mention *.[1-8].txt explicitly,
since we now get $(MANTXTS) via $(DOCS).
* NEWS: Document the above.
* Makefile (COMMON): Move README here ...
(DOCS): ... from here, as it talks about the public-domain status
of the files, and this should be in both tarballs.
* README: Add intro. Mention public-domain status of files.
Remove and reorganize some obsolete text, e.g., move 1989 release
info from here to NEWS's tail.
* NEWS: Document the above.
Reported by Elliott Hughes in
<http://mm.icann.org/pipermail/tz/2013-September/020376.html>.
* localtime.c (timezone) [USG_COMPAT]:
(altzone) [ALTZONE]: Now long, not time_t.
* strftime.c (_fmt): Use long, not int, to store timezone.
* NEWS: Document this.
* Makefile (set-timestamps): Use git's tformat rather than format,
to port to strict POSIX hosts where `` output in shell scripts
cannot end in a non-newline. Use git diff --quiet rather than git
diff --name-only, as it's simpler. Use touch -c for safety, and
-m to avoid setting last-access time, which we don't care about.
Diagnose files that don't match repository.
* NEWS: Document this.
