# ```cf3

# Do note that any options defined in this method does not apply to service
# promises without explicit template_method call for standard_services.

bundle agent standard_services(service,state)
# @brief Standard services bundle, used by CFEngine by default
# @author CFEngine AS
# @param service Name of service to control
# @param state The desired state for that service: "start", "restart", "reload", "stop", or "disable". "enable", "enabled", and "disabled" are also able to be used when systemd is detected. "active" and "inactive" states are supported for systemd managed hosts and can be used for controlling the services currently running state, but make no promises about the service state on boot.
#
# This bundle is used by CFEngine if you don't specify a services
# handler explicitly, and will work with systemd or chkconfig or other
# non-sysvinit service managers. It will try to automate service
# discovery, unlike `classic_services` which requires known service
# names. If it can't do the automatic management, it will pass control
# to `classic_services`.
#
# This bundle receives the service name and the desired service state,
# then does the needful to reach the desired state.
#
# If you're running systemd, systemctl will be used via `systemd_services`.
#
# Else, if chkconfig is present, it will be used.
#
# Else, if the service command is available, if will be used.
#
# Else, if the svcadm command is available, if will be used. Note you
# have to supply the full SMF service identifier.
#
# Else, control is passed to `classic_services`.
#
# Note you do **not** have to call this bundle from `services`
# promises. You can simply make a `methods` call to it. That would
# enable you to use systemd states like `try-restart` for instance.
#
# **Example:**
#
# ```cf3
# services:
#     "sshd" service_policy => "start"; # uses `standard_services`
#
# methods:
#     "" usebundle => standard_services("sshd", "start"); # direct
# ```
#
# Alternatively, since services promises are an abstraction around bundles, the service state can be promised via a methods type promise.
#
# ```cf3
#
# methods:
#     "SSHD should be running" usebundle => standard_services("sshd", "start");

bundle agent classic_services(service,state)
# @brief Classic services bundle
# @author CFEngine AS
# @author Tero Kantonen <prkele@gmail.com>
# @param service specific service to control
# @param state desired state for that service
#
# This bundle is used by `standard_services` if it doesn't have an
# automatic driver for the current service manager.
#
# It receives the service name and the desired service state, then
# does the needful to reach the desired state.
#
# **Example:**
#
# ```cf3
# services:
#     "ntp" service_policy => "start";
#     "ssh" service_policy => "stop";
# ```
#
# There's multiple ways you can add new services to this list.
# Here's few examples:
#
# a) The zeroconf mode; If the new service matches these rules,
#    you don't need to add anything to the standard_services:
#
#  1. Your init script basename = `$(service)`
#  2. Your init script argument = `$(state)`
#  3. Your init script lives in `/etc/init.d/` (for non-*bsd),
#     or `/etc/rc.d/` (for *bsd)
#  4. Your process regex pattern = `\b$(service)\b`
#  5. You call the init as `/etc/init.d/<script> <arg>` (for non-*bsd),
#     or `/etc/rc.d/<script> <arg>` (for *bsd)
#
# b) If the 1st rule doesn't match, but rest does:
#
#   Use the `baseinit[$(service)]` array to point towards your
#   init script's basename. For example:
#
# ```cf3
#    "baseinit[www]" string => "httpd";
# ```
#
#   This would fire up init script `/etc/init.d/httpd`, instead of
#   the default `/etc/init.d/www`. From `/etc/rc.d/` if you're on *bsd system.
#
# c) If the 4th rule doesn't match, but rest does:
#
#   Use the `pattern[$(service)]` array to specify your own
#   regex match. It's advisable to use conservative regex so
#   there's less chance of getting a mismatch.
#
# ```cf3
#    "pattern[www]" string => ".*httpd.*";
# ```
#
#   Instead of matching the default '\bwww\b', this now matches
#   your given string,
#
# d) 5th rule doesn't match:
#
#   If you can specify the init system used.
#    Currently supported: `sysvinitd`, `sysvservice`, `systemd`
#
# ```cf3
#     "init[www]" string => "sysvservice";
#     "init[www]" string => "sysvinitd";
#     "init[www]" string => "systemd";
# ```
#
#   ^^ The above is not a valid syntax as you can only use one `init[]`
#      per service, but it shows all the currently supported ones.
#
# ```cf3
#     "sysvservice" == /(usr/)?sbin/service
#     "sysvinitd"   == /etc/init.d/ (non-*bsd) | /etc/rc.d/ (*bsd)
#     "systemd"     == /bin/systemctl
# ```
#
# e) 2nd and 3rd rule matches, but rest doesn't:
#
#   Use a combination of the `pattern[]`, `baseinit[]` and `init[]`,
#   to fill your need.
#
# ```cf3
#     "baseinit[www]" string => "httpd";
#     "pattern[www]"  string => ".*httpd.*";
#     "init[www]"     string => "sysvservice";
# ```
#
# f) As a fallback, if none of the above rules match, you can also
#    define exactly what you need for each `$(state)`.
#
# ```cf3
#    "startcommand[rhnsd]"   string => "/sbin/service rhnsd start";
#    "restartcommand[rhnsd]" string => "/sbin/service rhnsd restart";
#    "reloadcommand[rhnsd]"  string => "/sbin/service rhnsd reload";
#    "stopcommand[rhnsd]"    string => "/sbin/service rhnsd stop";
#    "pattern[rhnsd]"        string => "rhnsd";
# ```
#
# If *any* of the `(re)?(start|load|stop)command` variables are set for
# your service, they take _priority_ in case there's conflict of intent
# with other data.
#
# Say you'd have the following service definition:
#
# ```cf3
#    "startcommand[qwerty]"   string => "/sbin/service qwerty start";
#    "stopcommand[qwerty]"    string => "/sbin/service qwerty stop";
#    "pattern[qwerty]"        string => ".*qwerty.*";
#    "baseinit[qwerty]"       string => "asdfgh"
#    "init[qwerty]"           string => "systemd";
# ```
#
# There's a conflict of intent now. As the `~command` definitions takes
# priority, this kind of service config for `qwerty` would execute the
# following commands:
#
# ```
#   start:   "/sbin/service qwerty start"
#   stop:    "/sbin/service qwerty stop"
#   restart: "/bin/systemctl asdfgh restart"
#   reload:  "/bin/systemctl asdfgh reload"
# ```
