At last, the announcement of a new stable series. This one's based off
0.5.2 but with a lot of the sharp corners shaved off, and lots of bug
I strongly suggest that everybody using 0.3.x or 0.5.x now bite the
bullet and switch to using 0.6.0, I probably won't make another release
on those branches now. There's a bit of a compatibility bump moving the
configuration directory, but I'll make sure that the 0.10 development
series is backwards compatible with it.
0.6.0 2009-07-09 "How appropriate, you fight like a cow"
* The licence for Upstart has been changed back to version 2 of the
* D-Bus 1.2.15 is now required, this is the current GIT HEAD
pending a 1.2.16 release.
* Configuration paths have changed. Global configuration now
resides in "/etc/init.conf" while jobs are now configured in
* Job configuration filenames must now end in ".conf"
* Default configuration files are now supplied in the "conf"
sub-directory of the source, and installed into "/etc/init".
These match the Debian/Ubuntu sysvinit configuration so may
require some tweaking for other distributions, but provide an
The old example-jobs tarballs are deprecated.
* The D-Bus interface remains unstable, to reflect this the current
interface name has changed to "com.ubuntu.Upstart0_6" and the
name of the job and instance interfaces have changed to match.
* The "EmitEvent" D-Bus method gains a wait argument, when given
as TRUE (the recommended setting) the method call will be blocked
until all effects of the event have finished. When FALSE the
method call will return once the event has been queued.
* The "Start", "Stop" and "Restart" D-Bus methods of jobs and
instances gain a similar wait argument.
* The Upstart D-Bus object now has "version" and "log_priority"
properties. The former is to obtain the version of the init daemon,
the latter allows you to obtain and change the logging priority.
* Job D-Bus objects now have "name", "description", "author" and
"version" properties to obtain the job name and the contents of
the equivalent job file fields for the others.
* Instance D-Bus objects now have "name", "goal", "state" and
"processes" properties to obtain the instance name, goal, state
and list of running processes and their pids respectively.
* The default D-Bus security policy now permits use of the "Get"
methods by all users, including obtaining values of properties.
* initctl has been rewritten with functionality more along the
lines of Upstart 0.3.x than before; since many distributions are
still shipping 0.3.x the summary of changes for the tool reflects
both changes from 0.3.x and 0.5.x
* The global "-p"/"--pid" argument has been dropped, since
communication is over D-Bus. New "--system" and "--dest" arguments
have been added to force communication over the system bus, and
specify the destination, instead of using the private socket (this
is the default when run as non-root to permit "list" and "status"
to work for ordinary users).
* The "-i"/"--id" and "--show-ids" options to commands have been
dropped since jobs no longer have ids.
* Since instances may now have names, these will be displayed in
brackets after the job name when one is present. The output of
the goal and state are now expressed as "start/running" instead
of "(start) running" to disambiguate.
* initctl "start" and "stop" now only output the final state of
the job, not intermediate states it passes through. When called
with "--no-wait", the commands now output a status before
returning (which may not be the final status).
* initctl "start", "stop" and "status" now only accept a single
job name. Further arguments are taken as KEY=VALUE environment
variables to pass to the job, replacing the previous "-e" option.
* There is a new initctl "restart" command, with matching
/sbin/restart symlink. This is the atomic equivalent of calling
"stop" and "start" with the exception that a stopped job will
not be started again.
* In keeping with the newer instance model, instance jobs are now
output on separate lines with their full names rather than
indented under a "master" instance.
* initctl "status" will exit non-zero if the job name was not
found. (Bug: #328323)
* initctl "status" now outputs information for multi-instance
jobs. (Bug: #331407)
* initctl "list" no longer accepts a pattern, use grep. Output
is no longer sorted.
* initctl "emit" no longer outputs changes that occur as a result
of the event.
* When initctl "emit" is called with "--no-wait", it will return
immediately. (Bug: #324890)
* initctl "emit" now only accepts a single event name. Further
arguments are taken as KEY=VALUE environment for the event,
replacing the previous "-e" option.
* initctl "jobs" and "events" have been dropped.
* initctl "log-priority" may be called without arguments, in
which case it will output the current priority. (Bug: #280529)
* initctl "reload" has been renamed to "reload-configuration"
to avoid confusion with reloading a job's configuration.
* initctl(8) man page updated. (Bug: #285753)
* runlevel no longer accepts the --set and --reboot arguments,
instead telinit and shutdown write these records into utmp and wtmp.
* runlevel(7) man page added to describe the runlevel event, and
the implementation of runlevels and System V compatibility in
Upstart. (Bug: #60429)
* telinit will no longer silently ignore the "a", "b" or "c"
* telinit now accepts the previously ignored "-e" argument, passing
the environment variables given along with the runlevel event.
* telinit now officially accepts the "q"/"Q" and "u"/"U" arguments,
the former will reload the Upstart configuration while the latter
will re-execute Upstart.
* telinit q will also attempt to reconnect to the D-Bus system bus
if the connection has not been made, or has been lost.
* reboot no longer silently ignores the "-t" option.
* reboot now silently ignores the "-n", "-i" and "-h" options; it
will no longer sync your disks, down your network interfaces or
spin down your hard drives. This functionality is all handled
by the kernel on a modern system. (Bug: #92685)
* reboot now writes a "shutdown" record to /var/log/wtmp, this means
that the "-w" option is honoured with its original intent. We
still silently ignore the "-d" option.
* shutdown message generation fixed to be more easily translatable.
* The TERM/KILL timeout, and other system timeouts, now use the
monotonic clock so are unaffected by system clock changes.
* Respawn detection now uses the monotonic clock so is unaffected
by system clock changes. (Bug: #389586)
* Significant improvement in the amount of manual pages included
with Upstart and their content. (Bug: #60429)
* A manual page refering people from /etc/inittab to /etc/init
is also included. (Bug: #72058)
