Make bug-reporting address more configurable
by Joseph S. Myers Nov. 13, 2012

Nov. 13, 2012

When distributing programs from tzcode as part of a larger software distribution, it can be desirable to redirect user bug reports to the bug-reporting system of that distribution as a whole (with a view to then passing along reports or fixes where it's determined that they don't relate to local modifications or packaging). This patch moves the bug-reporting address from being hardcoded in various strings to being in variables that are more convenient to modify in the packaging process. (Some people may wish to use an email address for bug reports, some a URL to a bug tracker and some a URL for instructions on bug reporting. But making the accompanying text configurable rather than just the address bit, to accommodate those variations better, would make things worse for i18n.) diff --git a/Makefile b/Makefile index 5a17164..cbda727 100644 --- a/Makefile +++ b/Makefile @@ -8,6 +8,9 @@ PACKAGE= tzcode # Version numbers of the code and data distributions.

tzcode2012j and tzdata2012j available
by Paul Eggert Nov. 13, 2012

Nov. 13, 2012

The 2012j release of the tz code and data is available. It reflects the following changes recently circulated on the tz mailing list: Libya moved to CET this weekend, but with DST planned next year. (Thanks to Even Scharning, Steffen Thorsen, and Tim Parenti.) Signatures now have the extension .asc, not .sign, as that's more standard. (Thanks to Phil Pennock.) The output of 'zdump --version', and of 'zic --version', now uses a format that is more typical for --version. (Thanks to Joseph S. Myers.) The output of 'tzselect --help', 'zdump --help', and 'zic --help' now uses tz(a)iana.org rather than the old elsie address. zic -v now complains about abbreviations that are less than 3 or more than 6 characters, as per Posix. Formerly, it checked for abbreviations that were more than 3. 'make public' no longer puts its temporary directory under /tmp, and uses the just-built zic rather than the system zic. Various fixes to documentation and commentary. For this release I did not find the time to carefully review Joseph S. Myers's suggestion about BUGEMAIL in <http://mm.icann.org/pipermail/tz/2012-November/018452.html>. At first glance the suggestion seems like a good one, and I'd like to put it into the next release. Here are links to the release files: http://www.iana.org/time-zones/repository/releases/tzcode2012j.tar.gz http://www.iana.org/time-zones/repository/releases/tzdata2012j.tar.gz ftp://ftp.iana.org/tz/releases/tzcode2012j.tar.gz ftp://ftp.iana.org/tz/releases/tzdata2012j.tar.gz Each release file has a GPG signature, which can be retrieved by appending ".asc" to the above URLs. Copies of these signatures are appended to this message. As usual, links to the latest release files are here: http://www.iana.org/time-zones/repository/tzcode-latest.tar.gz http://www.iana.org/time-zones/repository/tzdata-latest.tar.gz ftp://ftp.iana.org/tz/tzcode-latest.tar.gz ftp://ftp.iana.org/tz/tzdata-latest.tar.gz This release corresponds to commit dec96c09a2e3f735292a49929df29028d26c4f1c in the unofficial github repository at <https://github.com/eggert/tz>.

It would be great if the documentation could reflect this. Andy
