Fix EOVERFLOW-related problems noted by Chistos Zoulas.
...
See: http://mm.icann.org/pipermail/tz/2014-October/021692.html
* asctime.c (asctime_r): Remove now-unnecessary EOVERFLOW ifdef.
* localtime.c (timesub): Set errno to EOVERFLOW on overflow.
POSIX requires this.
(ctime, ctime_r): Return NULL instead of having undefined behavior
when the time stamp is out of struct tm range. NetBSD does this,
the standards allow it, and it's nicer for users.
* private.h (EOVERFLOW): Default to EINVAL on ancient hosts that lack it.
* NEWS: Document this.

Avoid (void) before calls.
...
Although the cast to void in usage like '(void) printf ("Hello")'
may have been helpful decades ago when Lint Was Your Friend,
nowadays such casts are not helpful. The tz code is currently not
consistent about this: sometimes the casts are present, and
sometimes absent. As they make the code harder to read, let's
remove them.
* asctime.c, date.c, ialloc.c, localtime.c, strftime.c, zdump.c, zic.c:
Don't cast calls to 'void'.
2014-08-25 08:19:47 -07:00
8f065f5aa9
* asctime.c, newctime.3, newtzset.3: Don't imply ASCII is required.

Restore 'register'.
...
* asctime.c (asctime_r, asctime):

Restore the uses of 'register', reverting that part of the
"More C modernization" patch. See Arthur David Olson in
<http://mm.icann.org/pipermail/tz/2012-October/018385.html >.

More C modernization.
...
* Makefile (typecheck): Add -D__time_t_defined to CFLAGS,
for glibc 2.15.
* asctime.c (asctime_r, asctime):
* date.c (main, dogmt, reset, nondigit, sametm, convert, checkfinal):
* ialloc.c (icatalloc):
* localtime.c (detzcode, detzcode64, settzname, tzload)
(typesequiv, getzname, getqzname, getnum, getsecs, getoffset)
(getrule, transtime, tzparse, tzset, localsub, gmtsub)
(leaps_thru_end_of, timesub, increment_overflow)
(long_increment_overflow, normalize_overflow)
(long_normalize_overflow, tmcomp, time2sub, time1, leapcorr):
* scheck.c (scheck):

(delta, show, abbr, dumptime):
* zic.c (main, dolink, itsdir, associate, infile, inrule)
(inzone, inzcont, inzsub, inleap, inlink, rulesub, convert64)
(writezone, doabbr, stringoffset, stringrule, stringzone)
(outzone, addtype, leapadd, adjleap, ciequal, itsabbr, byword)
(getfields, rpytime, newabbr, mkdirs):
Omit 'register', as it adds no value these days. See Christos Zoulas in
<http://mm.icann.org/pipermail/tz/2012-October/018376.html >.
* date.c (netsettime) [TSP_SETDATE]: Add forward decl.
Don't rely on implicit int. Now static. Use NULL, not 0.
* zdump.c: Include "limits.h".
(absolute_min_time, absolute_max_time): Compute at compile-time,
as the run-time tests relied on undefined behavior.
(checkabsolutes): Rename from setabsolutes. Just check, since
there's nothing to set now. All uses changed.

Assume C89.
...
* Makefile (GCC_DEBUG_FLAGS): Modernize for GCC 4.6.3 x86.
* asctime.c (asctime_r, asctime):
* date.c (main, dogmt, reset, wildinput, nondigit, oops, display)
(timeout, sametm, netsettime):
* difftime.c (difftime):
* ialloc.c (icatalloc, icpyalloc):
* localtime.c (detzcode, detzcode64, differ_by_repeat)

(increment_overflow, long_increment_overflow)
(normalize_overflow, long_normalize_overflow, tmcomp, time2sub)
(time2, time1, mktime, timelocal, timegm, timeoff, gtime)
(leapcorr, time2posix, posix2time):
* scheck.c (scheck):
* strftime.c (strftime, _fmt, _conv, _add, _yconv, _loc):
* zdump.c (my_localtime, abbrok, usage, main, yeartot)
(delta, abbr, dumptime):
* zic.c (memcheck, eats, eat, error, warning, main)
(dolink, itsdir, rcomp, associate, infile, gethms, inrule)
(inzone, inzcont, inzsub, inleap, inlink, rulesub, convert)
(convert64, puttzcode, puttzcode64, atcomp, is32, writezone, DO)

(outzone, addtt, addtype, leapadd, yearistype, lowerit, ciequal)
(itsabbr, byword, getfields, oadd, tadd, rpytime, newabbr)
(mkdirs, eitol):
Assume C89 or better. Mostly this consists of using function
prototypes. In a few places, prototypes are required for
portability to hosts where time_t does not promote to itself and
where a preceding prototype does not override a definition. But
while we're at it we might as well be consistent: it's safe to
assume at-least-C89 these days.
* ialloc.c (nonzero, imalloc, icalloc, irealloc, ifree, icfree):
Remove; no longer needed now that we assume C89 or better.
All callers changed to use malloc, calloc, realloc, free.
* localtime.c (getzname, getqzname, leaps_thru_end_of, transtime):
* zdump.c (delta, yeartot):
* zic.c (eitol):
Now pure.
* private.h, zdump.c (ATTRIBUTE_PURE): New macro.
* private.h (icalloc, imalloc, irealloc, icfree, ifree): Remove decls.
* zic.c: Remove no-longer-necessary forward decls.
(max_time, min_time): Now const.
(setboundaries): Remove.
2012-10-12 07:53:12 -07:00

Switch from SCCS to git.
...
Remove the SCCS keyword '%W%' from all files.
Mostly this just remove comments.
Remove trailing white space, too.
* Makefile (TZCODE_VERSION): New macro.
(version.h): New rule.
(tzselect): Interpolate TZCODE_VERSION.
(clean): Remove version.h.
(zdump.o, zic.o): Depend on version.h.
* asctime.c, date.c, difftime.c, ialloc.c, localtime.c, scheck.c:
* strftime.c, zdump.c, zic.c: Remove elsieid.
* private.h: Remove privatehid.
* tzfile.h: Remove tzfilehid.
* tzselect.h (TZCODE_VERSION): Rename from VERSION.
* zdump.c, zic.c: Include "version.h",
and use TZCODE_VERSION instead of elsieid.
