at 3.0:
at now has a lex/yacc grammer, which is an extension of POSIX.2 to
something more sensible. There's an atd, which can still simulate
atrun with the -s option.
at 3.1:
Tried to fix some races in the atd code by renaming
running jobs to "=" (thanks to aj@arthur.pfalz.de for
pointing out the bug).
at 3.1.1:
The last fix didn't work. New locking scheme: as soon as
a job starts, the file a00beef is hardlinked to =00beef.
a00beef is unlinked as soon as actual shell execution
starts. "=" - files are deleted as soon as their job
ends, or an hour after they should have run.
at 3.1.2:
cleanups: indent the source with OTBS
remove output file if it already exists, with a warning.
log attempts to run job twice
added -b option to atd
removed -b option from at (now batch calls "at -qb now")
revamp run_loop so -b works correctly
at 3.1.3:
Fixed "at 07:30" functionality for implicit tomorrow
Include yywrap if none can be found
at 3.1.4:
Set default batch maximum to 0.8
Changed install group to 'root'
at 3.1.5:
Merged Bjorn Helgaas' (helgaas@tomahawk.rsn.hp.com) patches:
* Use setresuid(2) if setreuid(2) is not available
(HP-UX 10)
* Use "chown user:group" instead of "chown user.group" for
HP-UX compatibility
* RELINQUISH_PRIVS slightly earlier in at.c,
since it doesn't depend on
* Change "volatile static" to "static volatile"
* Test for HAVE_ATTRIBUTE_NORETURN instead of __GNUC__
in daemon.h
Don't export SHELLOPTS (read-only variable in bash)
at 3.1.6:
Made 'noon', 'teatime' and 'midnight' work.
Reran autoheader so HP-UX compilation works.
at 3.1.7:
Made parser case-independent by specifying -i to flex
at 3.1.8:
Fixed spelling mistake in manpage
Created at_allow(5) and at_deny(5) manpages
Fixed bug where 'next monday' could be a synonym for today
Fixed spelling bug in parser (misspelled February)
Removed obsolete '-v' flag from atq
