* init/main.c (term_handler): Close the control connection if we
re-exec init, otherwise it won't be able to bind. Drop debugging.
* init/main.c (term_handler): It always helps if we dup2 the
right file descriptor.
* init/main.c: Use the TERM signal instead of USR1, as old init
used that for something else. Also rather than passing across
file descriptor numbers, use a fixed descriptor and just pass
"--restart". When we get that option we need to unmask signals
otherwise we sit there looking like a lemon.
* init/job.c (job_change_state): Don't free the event unless we
generate one.
* NEWS: Update.
* init/cfgfile.c (cfg_watcher): Ignore any file with '.' or '~'
* TODO: Update.
* init/main.c (main): Parse command-line arguments, specifically
look for --state-fd which we'll use for reexec. Don't do a couple
of things if we're passed this.

serialisation so that we can re-exec ourselves.
* init/job.h: Update.

* init/event.c (event_read_state, event_write_state): And similar
functions for serialising the event queue.
* init/event.h: Update.
* init/tests/test_event.c: Test the serialisation.
* init/cfgfile.c (cfg_read_job): Fix a bug, need to subtract current
time to get due time.
* upstart/job.c (job_goal_from_name, job_state_from_name)
(process_state_from_name): Add opposite numbers that convert a
string back into an enumeration.
* upstart/job.h: Update.
* upstart/tests/test_job.c: Test the new functions.
2006-08-31 Scott James Remnant <email address hidden>
* init/job.h (Job): Add respawn_limit, respawn_interval,
respawn_count and respawn_time members so that we can keep track of
runaway processes.

within respawn_interval, or reset it if we go over.

on startup.

not hard links.

* init/event.c (event_queue_run): Don't run the event queue while
paused.
* init/job.c (job_detect_idle): Don't detect idle jobs while paused.
* util/reboot.c: if we get the -w argument ("only write to wtmp")
we need to exit, and not behave as halt normally would.
* compat/sysv/runlevel.c (main): Add missing newline.
* compat/sysv/telinit.c (main): And here too.
* init/main.c (main): Check for idle after the startup event queue
has been run, otherwise we may just sit there.
* compat/sysv/Makefile.am (sbin_PROGRAMS): Build and install telinit
(telinit_SOURCES, telinit_LDFLAGS, telinit_LDADD): Details for
telinit binary.

* util/reboot.c (main): Drop the debugging set.
* init/cfgfile.c (cfg_job_stanza): Correct nih_alloc error.
* init/process.c (process_setup_environment): Guard memory alloc.
* init/job.c (job_set_idle_event): Likewise.
(job_change_state): And here too.
(job_run_command): Likewise.
* init/control.c (control_send): Likewise.
* init/cfgfile.c: And throughout this file.
* upstart/control.c (upstart_recv_msg): And once here too.
* upstart/control.h: Abolish the separate halt, reboot and poweroff
messages and replace with a single shutdown message that takes
an event name (for the idle event issued afterwards).
* upstart/control.c (upstart_send_msg_to, upstart_recv_msg): Handle
the new shutdown event type by just treating it as an event.

* util/shutdown.c: Send the UPSTART_SHUTDOWN event and let the user
specify anything they want, just give defaults.
This is quite a big change and abolishes level events entirely,
along with the event history. We now just treat events as a
transient queue of strings that go past, may cause things to change,
but are otherwise forgotten. This turns out to be much easier to
understand and has no real loss of power.
* init/event.c: Vastly simplify; gone are the separate notions of
edge and level events, instead we just treat them as one-shot
things that go past and are forgotten about.
* init/event.h (Event): Remove value member.
Update prototypes.
* init/tests/test_event.c: Update.

one that includes the job name and a description of the transition
instead of the new state.

* init/tests/test_job.c: Update.
* init/cfgfile.c (cfg_job_stanza): Drop "when" and "while".

"when" and "while".
* init/control.c (control_send, control_handle): Drop cases for
level events.

event handling so that only a name is read.
* upstart/control.h: Remove value/level event structures.
* upstart/tests/test_control.c (test_messages): Update.
* upstart/job.c (process_state_name): Not used for events, adjust
documentation so it doesn't lie.

shutdown into maintenance mode.
* init/control.c (control_handle): Place a message in the syslog
before halting, powering off or rebooting.

if shutdown is immediate, and when it actually happens. Include
the hostname as wall does.

* TODO: Update.
* util/shutdown.c: Implement shutdown utility along the same lines
as the sysvinit one, but with rather different code.
* util/initctl.c (main): Call setuid on the effective user id so
that we can be made setuid root and executable by a special group.
* util/reboot.c (main): Likewise.

user id, if we're effectively root, that's good enough.

* util/Makefile.am (sbin_PROGRAMS): Build and install reboot
(reboot_SOURCES, reboot_LDFLAGS, reboot_LDADD): Details for reboot

we may end up waiting for a signal before we process the event
we just issued.
2006-08-27 Scott James Remnant <email address hidden>
* util/shutdown.c: Template main function.

with halting, rebooting and powering off; or at least the appropriate
messages.
* upstart/control.h: Add control message structures for halting,
powering off and rebooting the machine.
* upstart/tests/test_control.c (test_messages): Run the tests.

poweroff or reboot to be issued the next time the system is idle.

to dump core while we carry on in the parent hopefully stepping over
the bad instruction.
