- <para>
- As of Bugzilla 2.20, users can configure Bugzilla to regularly annoy
- them at regular intervals, by having Bugzilla execute saved searches
- at certain times and emailing the results to the user. This is known
- as "Whining". The process of configuring Whining is described
- in <xref linkend="whining"/>, but for it to work a Perl script must be
- executed at regular intervals.
- </para>
-
- <para>
- This can be done by adding the following command as a daily
- crontab entry, in the same manner as explained above for bug
- graphs. This example runs it every 15 minutes.
- </para>
-
- <programlisting>*/15 * * * * cd <your-bugzilla-directory> ; ./whine.pl</programlisting>
-
- <note>
- <para>
- Whines can be executed as often as every 15 minutes, so if you specify
- longer intervals between executions of whine.pl, some users may not
- be whined at as often as they would expect. Depending on the person,
- this can either be a very Good Thing or a very Bad Thing.
- </para>
- </note>

- <para>
- Windows does not have 'cron', but it does have the Task
- Scheduler, which performs the same duties. There are also
- third-party tools that can be used to implement cron, such as
- <ulink url="http://www.nncron.ru/">nncron</ulink>.

- <para>
- Whining is a feature in Bugzilla that can regularly annoy users at
- specified times. Using this feature, users can execute saved searches
- at specific times (i.e. the 15th of the month at midnight) or at
- regular intervals (i.e. every 15 minutes on Sundays). The results of the
- searches are sent to the user, either as a single email or as one email
- per bug, along with some descriptive text.
- </para>
-
- <warning>
- <para>
- Throughout this section it will be assumed that all users are members
- of the bz_canusewhines group, membership in which is required in order
- to use the Whining system. You can easily make all users members of
- the bz_canusewhines group by setting the User RegExp to ".*" (without
- the quotes).
- </para>
-
- <para>
- Also worth noting is the bz_canusewhineatothers group. Members of this
- group can create whines for any user or group in Bugzilla using a
- extended form of the whining interface. Features only available to
- members of the bz_canusewhineatothers group will be noted in the
- appropriate places.
- </para>
- </warning>
-
- <note>
- <para>
- For whining to work, a special Perl script must be executed at regular
- intervals. More information on this is available in
- <xref linkend="installation-whining"/>.
- </para>

- <note>
- <para>
- This section does not cover the whineatnews.pl script. See
- <xref linkend="installation-whining-cron"/> for more information on
- The Whining Cron.

- <section id="whining-overview">
- <title>The Event</title>
-
- <para>
- The whining system defines an "Event" as one or more queries being
- executed at regular intervals, with the results of said queries (if
- there are any) being emailed to the user. Events are created by
- clicking on the "Add new event" button.
- </para>
-
- <para>
- Once a new event is created, the first thing to set is the "Email
- subject line". The contents of this field will be used in the subject
- line of every email generated by this event. In addition to setting a
- subject, space is provided to enter some descriptive text that will be
- included at the top of each message (to help you in understanding why
- you received the email in the first place).
- </para>
-
- <para>
- The next step is to specify when the Event is to be run (the Schedule)
- and what searches are to be performed (the Queries).
- </para>
-
- </section>
-
- <section id="whining-schedule">
- <title>Whining Schedule</title>
-
- <para>
- Each whining event is associated with zero or more schedules. A
- schedule is used to specify when the query (specified below) is to be
- run. A new event starts out with no schedules (which means it will
- never run, as it is not scheduled to run). To add a schedule, press
- the "Add a new schedule" button.
- </para>
-
- <para>
- Each schedule includes an interval, which you use to tell Bugzilla
- when the event should be run. An event can be run on certain days of
- the week, certain days of the month, during weekdays (defined as
- Monday through Friday), or every day.
- </para>
-
- <important>
- <para>
- Be careful if you set your event to run on the 29th, 30th, or 31st of
- the month, as your event may not run exactly when expected. If you
- want your event to run on the last day of the month, select "Last day
- of the month" as the interval.
- </para>
- </important>
-
- <para>
- Once you have specified the day(s) on which the event is to be run, you
- should now specify the time at which the event is to be run. You can
- have the event run at a certain hour on the specified day(s), or
- every hour, half-hour, or quarter-hour on the specified day(s).
- </para>
-
- <para>
- If a single schedule does not execute an event as many times as you
- would want, you can create another schedule for the same event. For
- example, if you want to run an event on days whose numbers are
- divisible by seven, you would need to add four schedules to the event,
- setting the schedules to run on the 7th, 14th, 21st, and 28th (one day
- per schedule) at whatever time (or times) you choose.
- </para>
-
- <note>
- <para>
- If you are a member of the bz_canusewhineatothers group, then you
- will be presented with another option: "Mail to". Using this you
- can control who will receive the emails generated by this event. You
- can choose to send the emails to a single user (identified by email
- address) or a single group (identified by group name). To send to
- multiple users or groups, create a new schedule for each additional
- user/group.
- </para>
- </note>
- </section>
-
- <section id="whining-query">
- <title>Whining Queries</title>
-
- <para>
- Each wining event is associated with zero or more queries. A query is
- a saved search that is executed on the schedule specified (see above).
- You start out with zero queries attached to the event (which means that
- the event will not run, as there will never be any results to return).
- To add a query, press the "Add a new query" button.
- </para>
-
- <para>
- The first field to examine in your new query is the Sort field. Queries
- are executed, and results returned, in the order specified by the Sort
- field. Queries with lower Sort values will run before queries with
- higher Sort values.
- </para>
-
- <para>
- The next field to examine is the Search field. This is where you
- choose the actual search that is to be run. Instead of defining search
- parameters here, you are asked to choose from the list of saved
- searches (the same list that appears at the bottom of every Bugzilla
- page). You are only allowed to choose from searches that you have
- saved yourself (the default saved search, "My Bugs", is not a valid
- choice). If you do not have any saved searches, you can take this
- opportunity to create one (see <xref linkend="list"/>).
- </para>
-
- <note>
- <para>
- When running queries, the wining system acts as if you are the user
- executing the query. This means that the whining system will ignore
- bugs that match your query, but that you can not access.
- </para>
- </note>
-
- <para>
- Once you have chosen the saved search to be executed, give the query a
- descriptive title. This title will appear in the email, above the
- results of the query. If you choose "One message per bug", the query
- title will appear at the top of each email that contains a bug matching
- your query.
- </para>
-
- <para>
- Finally, decide if the results of the query should be sent in a single
- email, or if each bug should appear in its own email.
- </para>
-
- <warning>
- <para>
- Think carefully before checking the "One message per bug" box. If
- you create a query that matches thousands of bugs, you will receive
- thousands of emails!
- </para>
- </warning>
- </section>
-
- <para>
- Once you have defined at least one schedule, and created at least one
- query, go ahead and "Update/Commit". This will save your Event and make
- it available for immediate execution.
- </para>
-
- <para>
- If you ever feel like deleting your event, you may do so using the "Remove
- Event" button in the upper-right corner of each Event. You can also
- modify an existing event, so long as you "Update/Commit" after completing
- your modifications.
- </para>
