From 03163139c9553c6ee4c26a73e21aaef5da22be45 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Fri, 3 Oct 2014 14:48:11 -0400 Subject: [PATCH] Fix bogus logic for zic -P option. The quick hack I added to zic to dump out currently-in-use timezone abbreviations turns out to have a nasty bug: within each zone, it was printing the last "struct ttinfo" to be *defined*, not necessarily the last one in use. This was mainly a problem in zones that had changed the meaning of their zone abbreviation (to another GMT offset value) and later changed it back. As a result of this error, we'd missed out updating the tznames/ files for some jurisdictions that have changed their zone abbreviations since the tznames/ files were originally created. I'll address the missing data updates in a separate commit. --- src/timezone/zic.c | 33 ++++++++++++++++++--------------- 1 file changed, 18 insertions(+), 15 deletions(-) diff --git a/src/timezone/zic.c b/src/timezone/zic.c index 2e38990323..13baf73d3c 100644 --- a/src/timezone/zic.c +++ b/src/timezone/zic.c @@ -1766,7 +1766,25 @@ writezone(const char *name, const char *string) if (pass == 1) puttzcode((long) ats[i], fp); else + { puttzcode64(ats[i], fp); + + /* Print current timezone abbreviations if requested */ + if (print_abbrevs && + (ats[i] >= print_cutoff || i == thistimelim - 1)) + { + unsigned char tm = typemap[types[i]]; + char *thisabbrev = &thischars[indmap[abbrinds[tm]]]; + + /* filter out assorted junk entries */ + if (strcmp(thisabbrev, GRANDPARENTED) != 0 && + strcmp(thisabbrev, "zzz") != 0) + fprintf(stdout, "%s\t%ld%s\n", + thisabbrev, + gmtoffs[tm], + isdsts[tm] ?
