Scott James Remnant | cf2e833 | 2009-07-06 20:32:07 +0100 | [diff] [blame] | 3 | * The licence for Upstart has been changed back to version 2 of the |
| 4 | GNU GPL. |
| 5 | |
| 6 | * Configuration paths have changed. Global configuration now |
| 7 | resides in "/etc/init.conf" while jobs are now configured in |
| 8 | "/etc/init" |
| 9 | |
Scott James Remnant | 545bbe3 | 2009-07-08 22:05:59 +0100 | [diff] [blame] | 10 | * Job configuration filenames must now end in ".conf" |
| 11 | |
Scott James Remnant | edb382a | 2009-07-08 20:43:16 +0100 | [diff] [blame] | 12 | * Default configuration files are now supplied in the "conf" |
| 13 | sub-directory of the source, and installed into "/etc/init". |
| 14 | |
| 15 | These match the Debian/Ubuntu sysvinit configuration so may |
| 16 | require some tweaking for other distributions, but provide an |
| 17 | excellent base. |
| 18 | |
| 19 | The old example-jobs tarballs are deprecated. |
| 20 | |
Scott James Remnant | cf2e833 | 2009-07-06 20:32:07 +0100 | [diff] [blame] | 21 | * The D-Bus interface remains unstable, to reflect this the current |
| 22 | interface name has changed to "com.ubuntu.Upstart0_6" and the |
| 23 | name of the job and instance interfaces have changed to match. |
| 24 | |
| 25 | * The "EmitEvent" D-Bus method gains a wait argument, when given |
| 26 | as TRUE (the recommended setting) the method call will be blocked |
| 27 | until all effects of the event have finished. When FALSE the |
| 28 | method call will return once the event has been queued. |
| 29 | |
| 30 | * The "Start", "Stop" and "Restart" D-Bus methods of jobs and |
| 31 | instances gain a similar wait argument. |
| 32 | |
| 33 | * The Upstart D-Bus object now has "version" and "log_priority" |
| 34 | properties. The former is to obtain the version of the init daemon, |
| 35 | the latter allows you to obtain and change the logging priority. |
| 36 | |
| 37 | * Job D-Bus objects now have "name", "description", "author" and |
| 38 | "version" properties to obtain the job name and the contents of |
| 39 | the equivalent job file fields for the others. |
| 40 | |
| 41 | * Instance D-Bus objects now have "name", "goal", "state" and |
| 42 | "processes" properties to obtain the instance name, goal, state |
| 43 | and list of running processes and their pids respectively. |
| 44 | |
| 45 | * The default D-Bus security policy now permits use of the "Get" |
| 46 | methods by all users, including obtaining values of properties. |
| 47 | |
| 48 | * initctl has been rewritten with functionality more along the |
| 49 | lines of Upstart 0.3.x than before; since many distributions are |
| 50 | still shipping 0.3.x the summary of changes for the tool reflects |
| 51 | both changes from 0.3.x and 0.5.x |
| 52 | |
| 53 | * The global "-p"/"--pid" argument has been dropped, since |
| 54 | communication is over D-Bus. New "--system" and "--dest" arguments |
| 55 | have been added to force communication over the system bus, and |
Scott James Remnant | 10a35f2 | 2009-07-08 20:05:46 +0100 | [diff] [blame] | 56 | specify the destination, instead of using the private socket (this |
| 57 | is the default when run as non-root to permit "list" and "status" |
| 58 | to work for ordinary users). |
Scott James Remnant | cf2e833 | 2009-07-06 20:32:07 +0100 | [diff] [blame] | 59 | |
| 60 | * The "-i"/"--id" and "--show-ids" options to commands have been |
| 61 | dropped since jobs no longer have ids. |
| 62 | |
| 63 | * Since instances may now have names, these will be displayed in |
| 64 | brackets after the job name when one is present. The output of |
| 65 | the goal and state are now expressed as "start/running" instead |
| 66 | of "(start) running" to disambiguate. |
| 67 | |
| 68 | * initctl "start" and "stop" now only output the final state of |
| 69 | the job, not intermediate states it passes through. When called |
| 70 | with "--no-wait", the commands now output a status before |
| 71 | returning (which may not be the final status). |
| 72 | |
| 73 | * initctl "start", "stop" and "status" now only accept a single |
| 74 | job name. Further arguments are taken as KEY=VALUE environment |
| 75 | variables to pass to the job, replacing the previous "-e" option. |
| 76 | |
| 77 | * There is a new initctl "restart" command, with matching |
| 78 | /sbin/restart symlink. This is the atomic equivalent of calling |
| 79 | "stop" and "start" with the exception that a stopped job will |
| 80 | not be started again. |
| 81 | |
| 82 | * In keeping with the newer instance model, instance jobs are now |
| 83 | output on separate lines with their full names rather than |
| 84 | indented under a "master" instance. |
| 85 | |
| 86 | * initctl "status" will exit non-zero if the job name was not |
| 87 | found. (Bug: #328323) |
| 88 | |
| 89 | * initctl "status" now outputs information for multi-instance |
| 90 | jobs. (Bug: #331407) |
| 91 | |
| 92 | * initctl "list" no longer accepts a pattern, use grep. Output |
| 93 | is no longer sorted. |
| 94 | |
| 95 | * initctl "emit" no longer outputs changes that occur as a result |
| 96 | of the event. |
| 97 | |
| 98 | * When initctl "emit" is called with "--no-wait", it will return |
| 99 | immediately. (Bug: #324890) |
| 100 | |
| 101 | * initctl "emit" now only accepts a single event name. Further |
| 102 | arguments are taken as KEY=VALUE environment for the event, |
| 103 | replacing the previous "-e" option. |
| 104 | |
| 105 | * initctl "jobs" and "events" have been dropped. |
| 106 | |
| 107 | * initctl "log-priority" may be called without arguments, in |
| 108 | which case it will output the current priority. (Bug: #280529) |
| 109 | |
| 110 | * initctl "reload" has been renamed to "reload-configuration" |
| 111 | to avoid confusion with reloading a job's configuration. |
| 112 | |
Scott James Remnant | 07b3224 | 2009-07-07 10:49:43 +0100 | [diff] [blame] | 113 | * initctl(8) man page updated. (Bug: #285753) |
| 114 | |
Scott James Remnant | ff87eaf | 2009-07-08 18:38:25 +0100 | [diff] [blame] | 115 | * runlevel no longer accepts the --set and --reboot arguments, |
Scott James Remnant | f24e55d | 2009-07-08 19:58:37 +0100 | [diff] [blame] | 116 | instead telinit and shutdown write these records into utmp and wtmp. |
Scott James Remnant | ff87eaf | 2009-07-08 18:38:25 +0100 | [diff] [blame] | 117 | |
| 118 | * runlevel(7) man page added to describe the runlevel event, and |
| 119 | the implementation of runlevels and System V compatibility in |
| 120 | Upstart. (Bug: #60429) |
| 121 | |
Scott James Remnant | 3aac713 | 2009-07-08 19:02:56 +0100 | [diff] [blame] | 122 | * telinit will no longer silently ignore the "a", "b" or "c" |
| 123 | runlevels. |
| 124 | |
Scott James Remnant | 3aac713 | 2009-07-08 19:02:56 +0100 | [diff] [blame] | 125 | * telinit now accepts the previously ignored "-e" argument, passing |
| 126 | the environment variables given along with the runlevel event. |
| 127 | |
| 128 | * telinit now officially accepts the "q"/"Q" and "u"/"U" arguments, |
| 129 | the former will reload the Upstart configuration while the latter |
| 130 | will re-execute Upstart. |
| 131 | |
Scott James Remnant | 461578a | 2009-07-08 19:30:12 +0100 | [diff] [blame] | 132 | * reboot no longer silently ignores the "-t" option. |
| 133 | |
| 134 | * reboot now silently ignores the "-n", "-i" and "-h" options; it |
| 135 | will no longer sync your disks, down your network interfaces or |
| 136 | spin down your hard drives. This functionality is all handled |
| 137 | by the kernel on a modern system. (Bug: #92685) |
| 138 | |
| 139 | * reboot now writes a "shutdown" record to /var/log/wtmp, this means |
| 140 | that the "-w" option is honoured with its original intent. We |
| 141 | still silently ignore the "-d" option. |
| 142 | |
Scott James Remnant | f24e55d | 2009-07-08 19:58:37 +0100 | [diff] [blame] | 143 | * shutdown message generation fixed to be more easily translatable. |
| 144 | (Bug: #102565) |
| 145 | |
Scott James Remnant | 1e812b5 | 2009-07-09 10:10:37 +0100 | [diff] [blame^] | 146 | * The TERM/KILL timeout, and other system timeouts, now use the |
| 147 | monotonic clock so are unaffected by system clock changes. |
| 148 | (Bug: #389588) |
| 149 | |
| 150 | * Respawn detection now uses the monotonic clock so is unaffected |
| 151 | by system clock changes. (Bug: #389586) |
| 152 | |
Scott James Remnant | b333820 | 2009-06-23 01:02:58 +0100 | [diff] [blame] | 153 | 0.5.3 2009-06-22 "Britain's Flag Carrier" |
| 154 | |
| 155 | * Fixed segfault when initctl status called with arguments. |
| 156 | (Bug: #388753) |
| 157 | |
| 158 | * Fixed segfault when initctl log-priority called with no argument. |
| 159 | (Bug: #280529) |
| 160 | |
| 161 | * Fixed shutdown to pass $INIT_HALT variable as last argument, not |
| 162 | as first. (Bug: #303574) |
| 163 | |
| 164 | * Added temporary support for "telinit u" until we have true re-exec |
| 165 | support. This will be replaced by an initctl command in future. |
| 166 | (Bug: #388742) |
| 167 | |
| 168 | * Corrected formatting of initctl(8) manpage. (Bug: #388745) |
| 169 | |
Scott James Remnant | 4ef6e28 | 2009-06-17 19:02:13 +0100 | [diff] [blame] | 170 | 0.5.2 2009-06-17 "Something, something, something, D-Bus" |
| 171 | |
| 172 | * The licence for Upstart has been updated to GNU GPL v3. |
| 173 | |
| 174 | * Overhaul of the automatically generated D-Bus bindings code, |
| 175 | fixing many issues with memory leaks, inconsistent return values |
| 176 | and loss of method returns after the method has taken place. |
| 177 | |
| 178 | * D-Bus 1.2.4 is now required, and must be patched to fix |
| 179 | https://bugs.freedesktop.org/show_bug.cgi?id=22316 |
| 180 | |
| 181 | * D-Bus Job objects now have "name", "description", "author" |
| 182 | and "version" properties. |
| 183 | |
| 184 | * D-Bus Instance object now have "name", "goal" and "state" |
| 185 | properties. |
| 186 | |
| 187 | * initctl now obtains the name properties for display instead of |
| 188 | printing the mangled object path component. (Bug: #299290) |
| 189 | |
| 190 | * D-Bus configuration updated now that the daemon is fixed to be |
| 191 | deny-by-default, and updated to avoid bare "send_interface" |
| 192 | stanzas. (Bug: #323021) |
| 193 | |
| 194 | * Fixed assertion caused by the post-start or pre-stop scripts |
| 195 | exiting after the main process of a respawning job had exited |
| 196 | (Bug: #381048) |
| 197 | |
| 198 | * The /proc filesystem need not be mounted if the "oom_adj" |
| 199 | configuration stanza is not used. (Bug: #259801) |
| 200 | |
| 201 | * Overly large values to configuration stanzas are now caught |
| 202 | and rejected. (Bug: #340134) |
| 203 | |
| 204 | * The --enable-compiler-warnings configure option has been |
| 205 | extended to add -Wextra, but turns off a few of the more extreme |
| 206 | warnings |
| 207 | |
| 208 | * GNU C Library v2.4 (or backported inotify support) is required |
| 209 | |
| 210 | * pkg-config 0.22 is now required, it probably was anyway but we |
| 211 | now explicitly check for it. |
| 212 | |
| 213 | * Dependency on Python for the D-Bus binding tool has been dropped |
| 214 | and replaced with a dependency on expat 2.0.0 |
Scott James Remnant | 619905b | 2009-01-29 06:23:08 +0000 | [diff] [blame] | 215 | |
| 216 | 0.5.1 2009-01-29 "Unexpected item in bagging area" |
| 217 | |
| 218 | * Major rewrite of the memory allocator used by Upstart; the |
| 219 | old allocator had several limitations and a few issues. |
| 220 | I must stress that none of the issues were known to affect |
| 221 | Upstart itself, however it pays to be prudent. |
| 222 | |
| 223 | * An issue where an object in a linked list would be freed after |
| 224 | the linked list was freed was fixed. Upstart had some twisty |
| 225 | code logic to work around it, which has now been dropped. |
| 226 | |
| 227 | * An issue where a string could fail to be appended in an OOM |
| 228 | situation was fixed; if Upstart is affected, this could cause |
| 229 | D-Bus Introspection data to be corrupted. |
| 230 | |
| 231 | * An issue where multiple socket watches being freed could lead |
| 232 | to bad memory access has been fixed; Upstart 0.5.0 included a |
| 233 | temporary fix for the D-Bus connection handling, this replaces |
| 234 | that with a proper fix that also corrects the same problem for |
| 235 | timers and other main loop watches that Upstart was not believed |
| 236 | to be affected by. |
| 237 | |
| 238 | * Compiler warnings when compiling the test suite with -O1 and |
| 239 | above have been fixed where found. |
| 240 | |
| 241 | * A race condition in the test cases for a process stopping with |
| 242 | SIGSTOP has been fixed, this could sometimes cause this test |
| 243 | to hang. |
| 244 | |
Scott James Remnant | 19580e4 | 2009-01-26 01:16:57 +0000 | [diff] [blame] | 245 | 0.5.0 2008-08-12 "One of those deaf-mutes" |
Scott James Remnant | 2e8760b | 2009-01-26 01:15:21 +0000 | [diff] [blame] | 246 | |
| 247 | * The relationship between job definitions and their running |
| 248 | instances has been overhauled completely. Jobs may have |
| 249 | zero or more instances, each one uniquely identified by |
| 250 | their instance name which is set by expanding the argument |
| 251 | to the "instance" stanza against the instance's environment. |
| 252 | |
| 253 | For example, a job with "instance $TTY" in its definition |
| 254 | will have new instances created when started with TTY=tty1 |
| 255 | and TTY=tty2, but starting again with TTY=tty1 will fail if |
| 256 | that instance is already running. |
| 257 | |
| 258 | * The default job configuration remains to be a singleton, |
| 259 | however this is now accomplished simply by having the |
| 260 | default for the instance stanza set to a static string. |
| 261 | |
| 262 | * Job events now include the instance name in a new $INSTANCE |
| 263 | variable, and will always have $UPSTART_INSTANCE set in the |
| 264 | environment of their processes. |
| 265 | |
| 266 | * Jobs may export environment from themselves into the job |
| 267 | events using the new "export" stanza. |
| 268 | |
| 269 | * Events no longer have both arguments and environment, |
| 270 | instead the order the environment is specified in is |
| 271 | remembered and is used when matching. |
| 272 | |
| 273 | * The "start on" and "stop on" stanzas may now only be |
| 274 | specified once, multiple events should be joined with the |
| 275 | new "or" operator. A new "and" operator exists as well, and |
| 276 | parentheses are permitted, allowing arbitrarily complicated |
| 277 | expression matches. |
| 278 | |
| 279 | * All environment from the matched start events is placed in |
| 280 | the job, with the list of matched events placed in the |
| 281 | $UPSTART_EVENTS variable, replacing the previous singular |
| 282 | $UPSTART_EVENT variable. |
| 283 | |
| 284 | * The matches for the "stop on" stanza may refer to variables |
| 285 | from the job environment, which comes from the "start on" |
| 286 | stanza. |
| 287 | |
| 288 | For example: |
| 289 | start on started apache or started httpd |
| 290 | stop on stopping $JOB |
| 291 | |
| 292 | * Job environment from the start command or events is |
| 293 | available to all scripts, including "pre-stop" and "post-stop". |
| 294 | |
| 295 | * Environment from the matched stop events is only available |
| 296 | to the "pre-stop" script, with the list of matched events |
| 297 | placed in the $UPSTART_STOP_EVENTS variable so that the list |
| 298 | of events that started the job is still available. |
| 299 | |
| 300 | * Environment is no longer lost after a respawn. |
| 301 | |
| 302 | * Environment from the kernel or initramfs may be included in |
| 303 | a job by use of the "env NAME" stanza without a value set. |
| 304 | |
| 305 | * The "started" event is no longer emitted if the pre-stop |
| 306 | script restarts the job, since the "stopping" event was |
| 307 | never emitted. |
| 308 | |
| 309 | * By default, jobs now have the most suitable settings for |
| 310 | a daemon process that would match what they would have had |
| 311 | by calling daemon(). In particular, this means that the |
| 312 | previous "service" stanza is now the default and tasks need |
| 313 | to specify a "task" stanza. It also means that if the job |
| 314 | really wishes to be a session leader (e.g. getty), it must |
| 315 | specify the new "session leader" stanza. |
| 316 | |
| 317 | * Processes that fork once may be supervised with the new |
| 318 | "expect fork" stanza, processes that fork twice (most |
| 319 | daemons) may be supervised with the new "expect daemon" |
| 320 | stanza and processes that do not fork may signal readiness |
| 321 | by SIGSTOP with the new "expect stop" stanza. |
| 322 | |
| 323 | * The "pid file", "pid timeout" and "daemon" stanzas have been |
| 324 | removed in favour of the new functionality. |
| 325 | |
| 326 | * "respawn" now works for tasks, this will repeat the task |
| 327 | until it finishes with a zero exit status or any other |
| 328 | specified by "normal exit". |
| 329 | |
| 330 | * "respawn limit" now only affects automatic respawns, not |
| 331 | those done by command. |
| 332 | |
| 333 | * If the main process fails to start due to exec() error, or |
| 334 | other process setup error, it will not be respawned. |
| 335 | |
| 336 | * "respawn limit" may be "unlimited". |
| 337 | |
| 338 | * The "stalled" event has been removed. |
| 339 | |
| 340 | * "logd" was not maintained, and did not function correctly, |
| 341 | so has been removed from the source. The "console logged" |
| 342 | stanza has also been removed. |
| 343 | |
| 344 | * New "oom" stanza allows adjustment of the OOM killer |
| 345 | priority of the process and may be "never" to inhibit it. |
| 346 | |
| 347 | * The configuration directory has now changed to |
| 348 | /etc/init/jobs.d |
| 349 | |
| 350 | * Configuration is still reloaded with inotify, but may be |
Scott James Remnant | 19580e4 | 2009-01-26 01:16:57 +0000 | [diff] [blame] | 351 | forced by sending init a HUP signal or with "initctl reload". |
Scott James Remnant | 2e8760b | 2009-01-26 01:15:21 +0000 | [diff] [blame] | 352 | |
| 353 | * Support for the STOP, CONT and TERM signals has been |
| 354 | removed. |
| 355 | |
| 356 | * libupstart and the native IPC mechanism has been removed, |
| 357 | communication is now via D-Bus which is a new dependency. |
| 358 | |
| 359 | * The dependency on D-Bus introduces build-dependencies on |
| 360 | pkg-config and Python. |
| 361 | |
| 362 | * The minimal recommended kernel version is now 2.6.24 |
| 363 | |
| 364 | * The compat directory has been removed, the utilities are now |
| 365 | considered part of Upstart. |
| 366 | |

| 384 | |
| 385 | * Fixed crasher caused by starting a job with a no-arguments event. |
| 386 | |
| 387 | * Initialisation order changed so that the control socket is opened |
| 388 | and configuration parsed after inherited file descriptors are closed |
| 389 | and the console opened. Otherwise if we inherit fewer than the |
| 390 | standard three file descriptors (e.g. from OpenVZ) we closed our |
| 391 | own control socket, etc. (Bug: #87173) |
| 392 | |

| 397 | * Missing inotify support detected correctly and warning suppressed. |
| 398 | |
| 399 | * Stanza names in configuration may no longer be placed inside quotes. |
| 400 | |
| 401 | * Fix dangling halt and poweroff symlinks when Upstart compiled |
| 402 | without --enable-compat=sysv. (Bug: #93356) |

| 404 | * Fix that --with-included-gettext did not include libintl.a |
| 405 | as it should have. (Bug: #117848) |
| 406 | |
| 407 | * Updated hacking requirements to Automake 1.10 and Gettext 0.16.1 |
| 408 | since this version of Automake makes it easier for package |
| 409 | maintainers because it causes us to ship libtool.m4 ourselves. |

| 412 | |
| 413 | * Fix an assertion error that occurred whenever a stop event for an |
| 414 | instance job was emitted. |
| 415 | |
| 416 | * Correct a bug where calling "stop" from a job without arguments |
| 417 | would stop the running job, and attempt to block until it was |
| 418 | stopped. This can obviously never happen since it won't stop until |
| 419 | stop unblocks. |
| 420 | |
| 421 | * Add "version" and "log-priority" commands to initctl. |
| 422 | |
Scott James Remnant | 79a3c9a | 2007-03-09 21:35:31 +0000 | [diff] [blame] | 423 | 0.3.7 2007-03-09 "Lines of communication" |
| 424 | |
| 425 | * The "normalexit" stanza has been changed to "normal exit". |
| 426 | |
| 427 | * The "respawn COMMAND" short-cut for specifying both "respawn" and |
| 428 | "exec" in the same stanza has been removed. Jobs that previously |
| 429 | used syntax such as: |
| 430 | |
| 431 | respawn /sbin/getty 38400 tty1 |
| 432 | |
| 433 | Should be changed to use: |
| 434 | |
| 435 | exec /sbin/getty 38400 tty1 |
| 436 | respawn |
| 437 | |
| 438 | While the shortcut saved a little typing, it caused confusion and |
| 439 | hid the fact that "exec" and "script" were both options for |
| 440 | respawning services. |
| 441 | |
| 442 | * The "on EVENT" stanza has been removed, change your jobs to use |
| 443 | the identical "start on EVENT" instead. This is because the "on" |
| 444 | stanza may be useful for other things in future. |
| 445 | |
| 446 | * Stanzas in job definitions may no longer be surrounded by single |
| 447 | or double quotes, allowing them to be turned into ordinary |
| 448 | tokens by quoting them. |
| 449 | |
| 450 | * Configuration of running jobs is no longer immediately changed |
| 451 | when the definition is changed on disk; the job must be stopped |
| 452 | first. If the job is an instance job, all instances must be |
| 453 | stopped before an instance of the changed job definition will be |
| 454 | started. |
| 455 | |
| 456 | This ensures that the post-stop process run when the job is stopped |
| 457 | matches the pre-start process run when it was started, and for |
| 458 | instance jobs ensures that any locking between them is identical. |
| 459 | |
| 460 | Jobs marked for deletion, or jobs that have not yet replaced |
| 461 | another, will not ordinarily show up in the output of initctl |
| 462 | "status" or "list" unless addressed by id. They cannot be |
| 463 | started or stopped, even when addressed by id. |
| 464 | |
| 465 | * Job definitions may safely omit "exec"/"script"; the job will stay |
| 466 | in the running state with no process until it is stopped manually |
| 467 | or by an event. |
| 468 | |
| 469 | This allows a service to define hardware configuration; for example |
| 470 | the mixer service could restore the ALSA mixer in its pre-start |
| 471 | script and save the mixer state in its stop script. "start mixer" |
| 472 | would restore the state, "status mixer" would show it was running |
| 473 | and "stop mixer" would save the state again and presumably mute it. |
| 474 | |
| 475 | * Sending the SIGPWR signal to init will emit the power-status-changed |
| 476 | event. A simple job can hook this event, check the /etc/powerstatus |
| 477 | file and take further action. |
| 478 | |
| 479 | * As well as their name, all jobs now also have a unique id exported |
| 480 | in the UPSTART_JOB_ID environment variable and viewable with initctl |
| 481 | by using the "--show-ids" option to "status" or "list". |
| 482 | |
| 483 | The unique id is changed whenever the job is reloaded from disk, or |
| 484 | whenever a new instance is started. "start" and "stop" now default |
| 485 | to UPSTART_JOB_ID if no arguments are given (falling back to |
| 486 | UPSTART_JOB if that is not present either). This means they act on |
| 487 | the current instance of the job, rather than spawning a new instance |
| 488 | or stopping all instances. |
| 489 | |
| 490 | "start", "status" and "stop" also accept a new "--by-id" option |
| 491 | which makes them expect job ids as arguments instead of job names. |
| 492 | |
| 493 | * The initctl "status" and "list" commands group instances of |
| 494 | instance jobs together in their output, rather than repeating them |
| 495 | without further clarification. E.g.: |
| 496 | |
| 497 | foo (instance) |
| 498 | (start) starting |
| 499 | (start) running, process 1000 |
| 500 | (stop) post-stop, process 1050 |
| 501 | |
| 502 | The "stop" command will stop all instances when given the name of |
| 503 | an instance job; individual instances can be stopped using "--by-id" |
| 504 | after obtaining the id from "status --show-ids". |
| 505 | |
| 506 | * Wildcard patterns of job names to be listed can be given as an |
| 507 | argument to the initctl "list" command. |
| 508 | |
| 509 | * Starting and stopping jobs with initctl will now block until the |
| 510 | job reaches its goal state, outputting all status changes and |
| 511 | process ids until the goal is reached and will also output an error |
| 512 | and exit with a non-zero status if the job fails. |
| 513 | |
| 514 | Remember that jobs default to being tasks, so "start" will actually |
| 515 | block until the job finishes and returns back to "(stop) waiting". |
| 516 | Use the "service" or "respawn" stanza to turn them into services to |
| 517 | that they only block until the "(start) running" state is reached. |
| 518 | |
Scott James Remnant | 4e97717 | 2007-02-10 21:24:29 +0000 | [diff] [blame] | 519 | 0.3.5 2007-02-10 "Wear flowers in your hair" |
| 520 | |
| 521 | * Serialisation of job state between upstart processes is disabled; |
| 522 | though upstart will still re-exec itself when sent the TERM |
| 523 | signal, the new copy will not have any of the state of the old. |
| 524 | This will be restored in a later release. |
| 525 | |
| 526 | * WARNING: if you have any job declared "console owner" which is |
| 527 | run by the "stalled" event, comment out the "start on" stanza |
| 528 | before sending the TERM signal -- otherwise the newly started |
| 529 | process will start that job, which will kill your running X |
| 530 | server. |
| 531 | |
| 532 | * logd and the "console logged" (default) option are currently |
| 533 | disabled, pending large-scale changes to the way that this |
| 534 | works. |
| 535 | |
| 536 | * Job scripts have been renamed; "start" to "pre-start" and |
| 537 | "stop" to "pre-stop". |
| 538 | |
| 539 | * A new "post-start" script has been added, it's run after the |
| 540 | main process has been started and the "started" event is not |
| 541 | emitted until it finished. |
| 542 | |
| 543 | * A new "pre-stop" script has also been added, it's run when a |
| 544 | request or event comes in to stop a job, before the "stopping" |
| 545 | event is emitted and before the job is killed. If this restarts |
| 546 | the job, it will not be stopped. |
| 547 | |
| 548 | * Job processes now have an UPSTART_JOB environment variable |
| 549 | containing the name of the job. |
| 550 | |
| 551 | * initctl start, stop and status will default to using UPSTART_JOB |
| 552 | if no arguments are given. Therefore you can just put "stop" |
| 553 | or "start" into a job script. |
| 554 | |
| 555 | * Where a job was started or stopped by an event, the processes |
| 556 | now have an UPSTART_EVENT environment variable containing the |
| 557 | name of the event. |
| 558 | |
| 559 | * Events may now have arguments and environment variables attached, |
| 560 | these can be specified with initctl, e.g. |
| 561 | |
| 562 | # initctl emit network-interface-up eth0 -eADDR=00:11:22:33:44:55:66 |
| 563 | |
| 564 | * These arguments can be matched in the job by placing them after |
| 565 | the event name for the "start on" or "stop on" stanzas: |
| 566 | |
| 567 | start on network-interface-up eth* |
| 568 | |
| 569 | Additional arguments in the event are assumed to match if not |
| 570 | specified in the job definition, and wildcards may be used within |
| 571 | the job definition as shown above. |
| 572 | |
| 573 | * The arguments are also passed to the script of any job started or |
| 574 | stopped by this event as positional arguments, and the environment |
| 575 | variables are placed into the environment of the job. |
| 576 | |
| 577 | * The set of events emitted due to a job state change have been |
| 578 | completely changed. The new events are as follows: |
| 579 | |
| 580 | started: this is emitted once the job is running and ready, and |
| 581 | receives the job name as an argument. |
| 582 | |
| 583 | stopped: this is emitted once the job has been fully stopped. As |
| 584 | well as the job name, if the job terminated normally it will have |
| 585 | the "ok" argument; otherwise it will have the "failed" argument |
| 586 | followed by the name of the script that failed ("running" for the |
| 587 | main job) and either an EXIT_STATUS or EXIT_SIGNAL environemtn |
| 588 | variable indicating why it failed. |
| 589 | |
| 590 | starting: this is emitted before the job is started (before even |
| 591 | the pre-start script is run). Arguments are as "started". The |
| 592 | job will not be started until this event has finished. |
| 593 | |
| 594 | stopping: this is emitted before the job is stopped (but after the |
| 595 | pre-stop script is run). Arguments are as "stopped". The job will |
| 596 | not be stopped until this event has finished. |
| 597 | |
| 598 | These events can be usefully combined as follows. |
| 599 | |
| 600 | If the "hal" job requires "dbus" to be running, and "hal" must be |
| 601 | stopped before "dbus" may stop: |
| 602 | |
| 603 | start on started dbus |
| 604 | stop on stopping dbus |
| 605 | |
| 606 | If the "tomcat" job believes that it must be running before "apache" |
| 607 | can run, and should not be stopped until "apache" has been stopped: |
| 608 | |
| 609 | start on starting apache |
| 610 | stop on stopped apache |
| 611 | |
| 612 | * The event named for the job has been completely removed; thus |
| 613 | jobs and events no longer share a namespace. |
| 614 | |
| 615 | * Jobs have goals to reach; for a task (the default), the goal is |
| 616 | to go from stopped, to started and back to stopped again. This |
| 617 | means that when used for the "starting" or "stopping" event, the |
| 618 | entire task has to complete before the referenced job can actually |
| 619 | be started or stopped. |
| 620 | |
| 621 | Services will normally only want the goal to be to go from stopped |
| 622 | to started; thus when used in "starting" in the example above, the |
| 623 | referenced job can be started once the service has been started |
| 624 | (and not stopped again). A service is defined by specifying either |
| 625 | "respawn" or "service" in the definition. |
| 626 | |
| 627 | * The list of exit codes that determine whether the main process |
| 628 | failed or succeeded can be specified by the "normalexit" |
| 629 | configuration stanza. The arguments to this stanza can be exit |
| 630 | codes or signal names, e.g. |
| 631 | |
| 632 | normalexit 1 99 100 INT QUIT |
| 633 | |
| 634 | Zero is implied in the list, unless the job is marked "respawn" |
| 635 | since for those jobs, this is the list of exit codes and signals |
| 636 | that cause the job to be not respawned. |
| 637 | |
| 638 | * There is no longer a respawning state, or "respawn script". Jobs |
| 639 | will instead be stopped and started through the same scripts. |
| 640 | |
| 641 | * Jobs marked with the "instance" stanza can be started multiple |
| 642 | times; each time they are started, a new instance is created. |
| 643 | |
| 644 | * If any job whose goal is changed by an event fail to reach their |
| 645 | new goal, a further "EVENT-NAME/failed" event will be emitted once |
| 646 | the event has finished being handled. |
| 647 | |
| 648 | This can be used to emit, for example, a "path-unmounting" event |
| 649 | and to not proceed to "path-unmounted" unless it succeeds. |
| 650 | |
| 651 | * initctl emit will block until the event has been handled; it will |
| 652 | also output job status information for any job changed by the event |
| 653 | and terminate with an exit status of 1 if any of those jobs failed |
| 654 | to reach their new goal. |
| 655 | |
| 656 | * The set of events emitted by the "telinit" compatibility command |
| 657 | have been changed. It now only emits a single "runlevel" event, |
| 658 | and supplies the new runlevel as an argument to it. |
| 659 | |
| 660 | You should change job files that use: |
| 661 | |
| 662 | start on runlevel-2 |
| 663 | |
| 664 | to use the following: |
| 665 | |
| 666 | start on runlevel 2 |
| 667 | |
| 668 | This means also that "stop on runlevel" would stop the job on |
| 669 | any runlevel change. |
| 670 | |
| 671 | * Neither the "telinit" nor "shutdown" commands now emit a |
| 672 | "shutdown" event, in fact, this event has been removed altogether. |
| 673 | "shutdown" now simply emits the appropriate runlevel event; |
| 674 | the -H and -P arguments set the INIT_HALT variable in the |
| 675 | environment of that event, just as it does in sysvinit. |
| 676 | |
| 677 | * Normal output from initctl, etc. is no longer prefixed "initctl:" |
| 678 | |
| 679 | * The "ctrlaltdel" event has been renamed to "control-alt-delete". |

| 682 | |
| 683 | * Fix leak of inotify file descriptor that could allow any process |
| 684 | on the system to remove upstart's watch on its configuration |
| 685 | directory. |
| 686 | |
| 687 | * New "emits" configuration stanza, used to list events that are |
| 688 | emitted by the job itself. Intended for use by front-ends to |
| 689 | draw event graphs and the like. |
| 690 | |
| 691 | * Dropped "depends" configuration stanza and all related code. |
| 692 | This will be replaced by the complex state mechanism. |
| 693 | |
| 694 | * Rewritten IPC code to be significantly simpler, with the goal of |
| 695 | having a stable interface once we hit the end of this milestone |
| 696 | series. |
| 697 | |
| 698 | * Rewritten configuration parser and inotify watch infrastructure |
| 699 | to be more maintainable in future. |
| 700 | |
| 701 | * Now supports systems where inotify is disabled. |
| 702 | |
| 703 | * Duplicate configuration stanzas are no longer permitted. |
| 704 | |
| 705 | * Bug fixes, especially concerning malloc failure. |

| 717 | |
| 718 | * Reverted logd behaviour from previous version, it's up to the |
| 719 | init scripts to send messages to the console if they wish. |
| 720 | |
| 721 | * Compatibility programs must now be explicitly enabled by using |

| 723 | |

| 755 | |
| 756 | * "control-alt-delete" event name changed to "ctrlaltdel". |
| 757 | |
| 758 | * "initctl shutdown EVENT" added that performs the same job as |
| 759 | "shutdown" but without all the usual warnings, timings, etc. |
| 760 | |
| 761 | * "logd" has now been written, if installed this is started by init |
| 762 | before sending the "startup" call and all jobs with "console logged" |
| 763 | (the default) will have their output sent to this daemon. It |
| 764 | currently just logs to /var/log/boot. |
| 765 | |
| 766 | * "shutdown -k" implemented. |
| 767 | |
| 768 | * The "shutdown" utility has been changed to generate "system-halt" |
| 769 | for "-H", "power-off" for "-P" and just "halt" if only "-h" given. |
| 770 | |
| 771 | * If "shutdown" is run when running under sysvinit, it will now |
| 772 | send the appropriate /dev/initctl message to allow upgrades. |
| 773 | |
| 774 | * "telinit S" implemented. |
| 775 | |
| 776 | * Instead of trying to start or stop jobs, "telinit" now just sends |
| 777 | "runlevel-X" events. |
| 778 | |
| 779 | * The "telinit" utility now ensures a "shutdown" event is sent |
| 780 | before switching to runlevel 0, 1 or 6. |
| 781 | |
| 782 | * If "telinit" is installed and init is called by the super-user, |
| 783 | "telinit" is invoked instead. |
| 784 | |
| 785 | * Basic manual pages included. |

| 802 | |
| 803 | * Events vastly simplified to just simple strings. |

| 807 | state transitions. |
| 808 | |
| 809 | * Services generate a "jobname" event when they are running. |
| 810 | |
| 811 | * Tasks generate a "jobname" event when they have finished. |
| 812 | |
| 813 | * The "shutdown" utility will generate a "shutdown" event followed |
| 814 | by one of "maintenance", "reboot", "halt" or "poweroff" or any |
| 815 | admin-specified event. |
| 816 | |
| 817 | * "stalled" event generated when no jobs are running or queued. |
| 818 | |
| 819 | * "control-alt-delete" event generated when that key combination |
| 820 | is pressed |
| 821 | |
| 822 | * "kbdrequest" event generated when Alt-UpArrow is pressed |
| 823 | |
| 824 | * Runaway respawning services will now be caught. |
| 825 | |
