== Version 0.17.0 Thank you to several new sponsors, as well as existing sponsors, for supporting this release. Current sponsors include github users: brentfrow, brazeon, and q66 (Daniel Kolesa, author of Chimera Linux). Development of Dinit has also received financial support from Artix Linux. I am grateful for all the support, both financial and otherwise, that has been received. Changes: * ... TBC * New "triggered" service type, similar to "internal" except that it requires an external trigger before it will start (start of a triggered service is delayed until the external trigger is received). * New "kill-all-on-stop" service option will cause dinit to kill all (other) processes just before stopping the service. This can be used to ensure a cleaner system state and that filesystems can be unmounted (for example). Use with care; see dinit-service(5) for details. * "shutdown" now runs (if present) user-provided shutdown hooks; see shutdown(8) for details. * "dinitctl" now supports the "--use-passed-cfd" argument (as for shutdown). * Meson build system added (as an alternative to the existing makefile-based build) by Mobin Aydinfar. == Version 0.16.1 (Bugfix release for 0.16.0) This release contains bug fixes for the previous release. Changes: * Fix issue where dependencies could stop before there dependents had stopped. * Fix issue where startup could fail if control socket location was not writable when dinit started. * Fix for dinitctl crashing due to an exception when a service description contained certain syntactical errors. * Fix nonsensical (but harmless) error message when loading services (when the service description is found in a directory that is not the first directory searched) (Daniel Kolesa). * Fix issue with example rootfscheck.sh script (Mobin Aydinfar). * Minor build system improvements (Daniel Kolesa). * Minor documentation updates. == Version 0.16.0 (Alpha release #8) This release contains some new features and bug fixes. Changes: * "before" and "after" relationships can now be specified for services. These can be used to control startup order without creating explicit dependencies between services. * The "restart" command of dinitctl will now also restart hard dependents if the "--force" option is used (previously the "--force" option was ignored, and the command would fail if a dependent blocked the restart). Changes contributed by Duncan Overbruck. * The "-t" (or "--service") command-line option has been implemented to allow unambiguously specifying that the next argument is a service name. This can be used when booting Linux to select a target service or services (dinit otherwise ignores potential service names in this scenario, since the Linux kernel sometimes passes through kernel options to init). Implemented by Mobin Aydinfar. * The dinit daemon itself supports S6-compatible readiness notification (for when run under another supervision system or controlling process). The "-r " command line argument specifies the file descriptor to write the notification to. Contributed by Daniel Kolesa. * Environment files (including per-service file as specified by env-file service setting): support for commands !clear, !unset and !import. These give more flexibility in how much of the original environment to expose to service processes. See the dinit(8) man page for more information. * The dinitctl utility provides more information if a service fails to start (avoiding the need to query the status separately or check logs to get the same information). * Fix bug with cgroup root path extraction where the path was longer than 64 characters (found by Github continuous integration builds as implemented by Mobin Aydinfar). * Fix bad pointer bug manifesting with very short command strings (reported by Duncan Overbruck). * Reloading a service now checks for (and disallows) cyclic dependencies. * Minor fix to service examples, contributed by Firas Khalil Khana. * Various minor build/install fixes. Other: * Github continuous integration was set up by Mobin Aydinfar == Version 0.15.1 (Alpha release #7) This contains minor fixes for the previous release. Changes: * Remove extra newline which was printed after service description error log messages. * Install dinit-monitor as part of "make install". == Version 0.15.0 (Alpha release #6) This release contains bug fixes and new features. Changes: * New "dinit-monitor" command can be used to perform notifications (via an external command, such as notify-send) when a service changes state. This is primarily intended for users running dinit in "user mode" rather than for system instances of dinit, although it works in either case. See the dinit-monitor(8) manual page for details. * Support on Linux for running service processes in a cgroup, via the "runs-in-cgroup" service setting. Cgroups must be mounted/created outside of dinit (eg via an early service), there is no support for this in dinit itself. See the dinit-service(5) manual page for details. * "dinitctl enable", "dinitctl disable" and "dinitctl rmdep" now give better feedback in various situations. For example, "dinitctl disable" will warn if a disabled service has other dependents (which may cause it to start anyway). * When parse errors occur in service description files, the relevant line number should now be reported (by dinitcheck, or in the dinit log). * Environment variable substitution in command lines is now performed for the "stop-command" setting in exactly the same way as for the "command" setting. Previously, by oversight, substitution was not performed for the "stop-command" setting. * Fix: start timeout was not being honoured for service restarts. == Version 0.14.0 (Alpha release #5) This release contains bug fixes and a new feature. Changes: * "stop-command" service parameter can now be applied to process and bgprocess services. If specified for these service types, the specified command is used to stop the service. * "dinitctl status" now reports launch stage and error for services which failed to execute. Example output: $ src/dinitctl status mpd Service: mpd State: STOPPED (could not be launched) Stage: executing command Error: No such file or directory * Fixes bug where "dinitctl status" command would sometimes report an error. * Fixes a (situational, unlikely) bug where a bgprocess state could get stuck. * Fixes a potential memory corruption / crash bug occurring in out-of-memory situations when adding a dependency to a service (via "dinitctl reload" or "dinitctl add-dep"). == Version 0.13.0 NOTE: This release has some minor backwards-incompatible changes. Please read these notes carefully. This release includes changes contributed by Daniel Kolesa. Changes: * A new dinitctl subcommand, "status", can be used to query extended status information for an individual service. * The default directory for user services has moved to ~/.config/dinit.d (rather than ~/dinit.d). * Some service settings now expand environment variables (given in the form $VARNAME, in any location that it appears within the setting value). The affected settings are: socket_path, logfile, env_file, working_dir and pid_file. * The variable substitution in command lines (which remains dependent on the 'sub-vars' load option, for now) uses the same substitution rules and logic as for other settings. In particular, this means that a variable expansion can occur as part of a command line argument (previously it always replaced whole arguments). * The dinitctl program now uses the value of the DINIT_SOCKET_PATH environment variable, if set, as the default control socket path. (If not set, behaviour is the same as for previous versions). * A "poweroff" symlink for shutdown will be installed alongside other symlinks ("reboot", "halt" etc). This allows integration in environments that expect such a command to be available. == Version 0.12.0 This is the third Alpha release, issued as a follow-up to the previous Alpha releases. It contains a number of minor improvements. Changes: * A new "--ignore-unstarted" option to dinitctl, causing it to return success when attempting to restart a service which is not started (including when no service description for it exists). * Add an "always-chain" service option, so that chaining to another service (as specified via the "chain-to" setting) becomes unconditional. Feature contributed by Alexander Sherikov. * Add support for multiple service directories to be specified (via multiple --services-dir options). Feature contributed by Alexander Sherikov. * Improve control socket creation / stale socket removal. Previously, a system instance would unconditionally unlink a pre-existing socket file, and non-system instances would fail if a pre-existing socket file existed (even if it was not active, i.e. no dinit instance was accepting connections on it). Now, if there is an existing socket file, dinit will attempt to connect to it, and will refuse to start if this succeeds, or unlink it otherwise. Unfortunately this cannot be done atomically, so it should not be relied on as a general means to prevent more than one instance of dinit from starting. == Version 0.11.0 This is a second Alpha release, issued as a follow-up to the previous Alpha release. It contains some minor bugfixes and a number of other improvements (all detailed below). Important: the default system socket location has changed. If version 0.11 of shutdown, halt etc are installed, they may not be able to communicate with the already-running (v0.10.0 or prior) dinit daemon. In this case, to shut the system down, use: dinitctl -p /dev/dinitctl shutdown Important: the "no-sigterm" option has been removed. To specify that no SIGTERM signal should be sent to a process to stop it, specify a different signal (or "none") via the "term-signal" setting. It is no longer possible to have both SIGTERM and an additional signal sent, but the settings should be less confusing. Changes: * dinit and dinitctl now support --version command line argument. * Improved diagnostic message if a service description file exists but can't be opened. * Default system socket location has changed from /dev/dinitctl to /run/dinitctl (see note above). * Active status is indicated in "dinitctl list" output. Square brackets indicate a service is marked active (i.e. it has been explicitly started) and curly brackets indicate a service that has started due to being the dependent of an active service. * The "dinitcheck" utility now performs a number of additional checks. * Better feedback is provided for various "dinitctl" commands. The affected service name is reported for any status update. * Fixed bug processing rlimit settings. * Fixed issue with interpreting unwanted command line parameters passed from linux kernel as service names. == Version 0.10.0 This release is a major step towards a version 1.0 release. It should be considered an Alpha release; core functionality is complete but some ancillary functionality is still unimplemented. It is believed to be of good quality but bugs may be present. * When not running as system init, dinit will now fail to start if the control socket cannot be opened. In particular this should prevent accidentally starting multiple instances of dinit (and all services). * Services of type bgproc will no longer load if the pid-file setting is not supplied. Previously such services could be started, but stopping them would leave the process running. * Re-worked manual service stop (via command). Previously, manually stopping a service would inhibit automatic restart of the service, but not of its dependents; this meant that the service might still restart due to a dependent. In this version, manually stopping a service inhibits restart of the service and all dependents (note that the --force option is required, as previously, in order to stop a service which has active dependents). * Re-worked soft dependency handling slightly. A dependency now (re-)attaches to its dependent if it starts (or starts again) while the dependent is started. This leads to overall more consistent behaviour (and is simpler to implement properly). * Re-worked pinning. A service that is pinned stopped can now prevent dependents from starting (the behaviour is the same as if the service failed to start). * Support start-timeout setting for process services. Previously this setting was ignored for such services. It is mostly useful for services which also have readiness notification configured (since otherwise, a process service is considered started as soon as it begins execution). * If a process-based service fails to restart, restart of dependent services will be inhibited. This should prevent repeated attempts to launch a failing process caused by a restarting dependent service. * Fixed some cases where service target state would not be set correctly. This could cause output of "dinitctl list" to incorrectly show that a service would restart after stopping, when in fact it would remain stopped. * Fixed various corner-case bugs in service management. == Version 0.9.1 This is a bug-fix release. * Fix a service getting stuck in the "stopping" state, if a dependent is set to auto-restart ("restart = true"). == Version 0.9.0 This release includes some new functionality and a rework of the chain-load mechanism. * The service specified via the "chain-to" setting will now only be started if the initiating service completes successfully, i.e. if it terminates normally (with an exit code of 0) and only if it is not manually stopped. * New option "--container" (-o) inhibits system management functions (such as machine shutdown/restart) that are normally enabled when dinit runs as process ID 1. A complementary "--system-mgr" (-m) option enables system management (even when not running as PID 1). * Fixed pinned-started services stopping when released by a dependent service, instead of remaining in the started state, and some other bugs related to pinning. Some issues may remain to be fixed in a later release. == Version 0.8.2 This is a bug-fix release. * Fixed group not being set correctly when "run-as" or "socket-uid" were used. * Fixed "dinitctl rm-dep" command * Fixed bug preventing shutdown when auto-restart services were configured * Fixed smooth recovery of bgprocess services == Version 0.8.1 This is a bug-fix release. * Fixed crash on service load error. * Fixed an unchecked allocation leading to possible unexpected termination. * Fixed a slow memory leak (in the bundled Dasynq library). * Fixed --help option for "dinitcheck" not working. * Fixed badly formatted error message from process launch failure. * Fixed issue where log file would not always be flushed on exit. * Fixed "dinitcheck" crashing if service description could not be found. == Version 0.8.0 This release includes major usability features. * New command "dinitcheck" checks service descriptions for errors (without attempting to load or start the service). Checks the named service(s) and any dependencies. * Service descriptions can now be reloaded, using "dinitctl reload ". This works for services which are started, with some restrictions, and for services which are stopped, and allows dependencies to be altered. * dinitctl now defaults to the system process socket location when run as root. This means that using '-s' is no longer necessary (it is still supported for backwards compatibility). A new '-u' option can be used to communicate with the user daemon, if there is one. == Version 0.7.0 This release adds a minor feature, and includes a re-work of some base functionality (which should not affect most use cases). * dinitctl "restart" command added. Re-starts an already-running service without affecting activation or dependency links. * dinitctl "stop" command now requires a `--force` option if dependents of the specified service would also need to stop. * dinitctl "wake" command now reconnects dependency links from dependents of the specified service, and can only be used if at least one such dependent is started. == Version 0.6.1: This is a bug-fix release with several minor fixes: * Resource limits were not properly being set. * Prevent early termination when standard input is closed or set to a device which cannot be watched for input. * Control protocol fix, possibly not affecting any real usage. == Version 0.6.0: This release adds a number of minor features: * Better behaviour when boot fails. User can choose an action from reboot, resume boot process, start the "recovery" service, or power-off. * New service settings for limiting resources at the process level: "rlimit-nofile", "rlimit-core", "rlimit-data", "rlimit-addrspace". Both hard and soft limits can be set. See dinit-service(5) for details. * New "env-file" setting allows per-setting environment to be specified via a file. The file is re-read each time the service process is started. * Added a "--quiet" option to suppress console output from Dinit. * Dinit when run as a user daemon no longer logs via syslog. Logging to file can still be enabled via the "-l"/"--log-file" option. * Added a "--socket-path"/"-p" option to dinitctl, to specify the socket path for communication with the dinit daemon. A number of minor bugfixes and other improvements are also implemented. An integration test framework has been added with a small number of tests, to complement the existing unit tests. == Version 0.5.2: This is a bug-fix release for several minor issues which have been found in the preceding release (0.5.1). * Fix logging failure after log buffer becomes full. * Fix readiness-fd notification not immediately updating service states. * Fix use of old settings in sample configuration for Linux. * Re-create control socket file node if it "disappears". Should solve issues if root filesystem is mounted read-write on boot. * Fix potential issue with service launch failure for services using a fixed notification fd. == Version 0.5.1: This is a bug-fix release for several issues of varying severity which have been found in the preceding release. * Improved logging behaviour when a service runs "on console" for a very short time. * Fix for crash due to SIGALRM on OpenBSD. * Fixes for compiling with Musl C library. * Fix dinitctl "enable" and "disable" commands when path to service directory is absolute. * "termsignal" setting renamed "term-signal" and now supports "KILL" signal. "termsignal" is still supported for compatibility with existing service descriptions. * Other minor fixes. == Version 0.5.0: This version adds S6-compatible readiness notification support, and adds support for updating the "utmp" database when services start/stop (this functionality should be avoided if possible since the "utmp" database is mostly an historical artifact, and system support is often prone to issues which allow unprivileged users to prevent updates and deny or delay logins; however, utilities such as "who" may depend on the database being updated appropriately). Other changes: * Add "-u" command line option to force running dinit as a user instance. * Add a "chain-to" service property to better support recovery services. * Add a "shares-console" service option to allow running services "on the console" without having them own it exclusively. * Add "inittab-id" and "inittab-line" service settings for utmp support. * Minor bugfixes. == Version 0.4.0: This version focuses on being more "distribution friendly". It adds mechanisms to add and remove dependencies, either temporarily or persistently, between services without manual editing of service description files. Changes: * A new service description directive, "waits-for.d", allows specifying a directory for which the contents (filenames) are read as dependencies. This provides a convenient way to add and remove dependencies to service descriptions without editing the textual service description file. * dinitctl has new commands, "add-dep" and "rm-dep", to add or remove a dependency between services. The dependency is not persisted and won't survive a restart. Check the man page for details. * dinitctl has new commands, "enable" and "disable". These permanently enable/disable a service for some target ("boot" by default) by creating/destroying a symbolic link in the waits-for.d directory specified in the service description (and create/remove waits-for dependency dynamically). Check the man page for details. * A code style guide has been added (in the "doc" directory). * More tests, minor bugfixes.
