[svn] * src/util.c: localTimeDiff() cached its value and recalculated it every
hour of clock time, regardless of the time the calculated was based on.
This is potentially dangerous at daylight saving changes. So instead
use the cached last result only when the new request is to be based on
a time in the same hour as the cached result.
* src/util.c: Replace the alternate Utl_mktimeGMT() implementation used when
timegm() is not available. The previous version, as suggested by the
glibc timegm() man page, used setenv() and unsetenv() for changing the
environment. These aren't POSIX function, and the POSIX putenv()
(a) is tricky to manage if the same var is being constantly update and
memory isn't to leak, and (b) provides no way to remove an environment
entry. So change to an implementation Wget uses. This should compile on
not glibc systems - the previous version failed to build on Solaris.

------------------------------------------------------------------------------- NOFFLE FAQ ------------------------------------------------------------------------------- Q: What is the difference between NOFFLE and leafnode? A: NOFFLE uses less resources (disk space and bandwidth). Downloading groups in overview mode is several times faster, because it uses the XOVER command instead of HEAD. In addition, there is the quasi-transparent mode, when online, which allows to browse through groups and cache everything without subscribing. NOFFLE is GPLed, leafnode isn't. ------------------------------------------------------------------------------- Q: I subscribe to groups, but get a "Retreiving failed" message for every requested article. A: Some news server do not allow retrieving articles by message-ID. You cannot use NOFFLE together with these servers presently. ------------------------------------------------------------------------------- Q: I changed the server in the config files, but the new groups do not appear. A: You should run 'noffle --query groups' again. If you want all old group information deleted, you should remove the file data/groupinfo.gdbm in the spool directory before. ------------------------------------------------------------------------------- Q: The Emacs news reader GNUS hangs while getting active list from server. A: This is a known phenomena and I believe that it is a bug with GNUS, because the log files show correct handling of client commands by noffle. ------------------------------------------------------------------------------- Q: What is the NOFFLE 'online' mode? A: NOFFLE can be optionally switched into 'online' mode. When in online mode any newsgroup can be read and the selected articles are fetched immediately from the remote server if not present locally. Regardless of the settings in noffle.conf, NOFFLE will not automatically subscribe to any newsgroup when in online mode. Online mode is therefore useful for quickly sampling the content of potentially interesting newsgroups. To enter online mode, run 'noffle --online'. To return the regular offline mode, run 'noffle --offline'. If you net connection is via dial-up, you may find it convenient to do this in your ip-up and ip-down scripts, though if you do you'll have to remember that NOFFLE's behaviour will be subtly different when you are dialled out. ------------------------------------------------------------------------------- Q: Can I read any article in 'online' mode? A: No. You cannot read groups that are not known to NOFFLE, or articles that NOFFLE has already expired. NOFFLE will not refetch expired articles.
