+ Boolean Charts + + Highly advanced querying is done using Boolean Charts. + + + The boolean charts further restrict the set of results + returned by a query. It is possible to search for bugs + based on elaborate combinations of critera. + + + The simplest boolean searches have only one term. These searches + permit the selected left field + to be compared using a + selectable operator to a + specified value. + Using the "And," "Or," and "Add Another Boolean Chart" buttons, + additonal terms can be included in the query, further + altering the list of bugs returned by the query. + + + There are three fields in each row of a boolean search. + + + + + Field: + the items being searched + + + + + Operator: + the comparison operator + + + + + Value: + the value to which the field is being compared + + + +
+ Pronoun Substitution + + Sometimes, a query needs to compare a field containing + a user's ID (such as ReportedBy) with + a user's ID (such as the user running the query or the user + to whom each bug is assigned). When the operator is either + "equals" or "notequals", the value can be "%reporter%", + "%assignee%", "%qacontact%", or "%user%." The user pronoun + referes to the user who is executing the query or, in the case + of whining reports, the user who will be the recipient + of the report. The reporter, assignee, and qacontact + pronouns refer to the corresponding fields in the bug. + +
+
+ Negation + + At first glance, negation seems redundant. Rather than + searching for +
+ + NOT("summary" "contains the string" "foo"), + +
+ one could search for +
+ + ("summary" "does not contain the string" "foo"). + +
+ However, the search +
+ + ("CC" "does not contain the string" "@mozilla.org") + +
+ would find every bug where anyone on the CC list did not contain + "@mozilla.org" while +
+ + NOT("CC" "contains the string" "@mozilla.org") + +
+ would find every bug where there was nobody on the CC list who + did contain the string. Similarly, the use of negation also permits + complex expressions to be built using terms OR'd together and then + negated. Negation permits queries such as +
+ + NOT(("product" "equals" "update") OR + ("component" "equals" "Documentation")) + +
+ to find bugs that are neither + in the update product or in the documentation component or +
+ + NOT(("commenter" "equals" "%assignee%") OR + ("component" "equals" "Documentation")) + +
+ to find non-documentation + bugs on which the assignee has never commented. + +
+
+ Multiple Charts + + The terms within a single row of a boolean chart are all + constraints on a single piece of data. If you are looking for + a bug that has two different people cc'd on it, then you need + to use two boolean charts. A search for +
+ + ("cc" "contains the string" "foo@") AND + ("cc" "contains the string" "@mozilla.org") + +
+ would return only bugs with "foo@mozilla.org" on the cc list. + If you wanted bugs where there is someone on the cc list + containing "foo@" and someone else containing "@mozilla.org", + then you would need two boolean charts. +
+ + First chart: ("cc" "contains the string" "foo@") + + + Second chart: ("cc" "contains the string" "@mozilla.org") + +

+ Whining + + + 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. + + + + + 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). + + + + 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. + + + + + + For whining to work, a special Perl script must be executed at regular + intervals. More information on this is available in + . + + + + + + This section does not cover the whineatnews.pl script. See + for more information on + The Whining Cron. + + + +
+ The Event + + + 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. + + + + 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). + + + + The next step is to specify when the Event is to be run (the Schedule) + and what searches are to be performed (the Queries). + + +
+ +
+ Whining Schedule + + + 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. + + + + 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. + + + + + 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. + + + + + 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). + + + + 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. + + + + + 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. + + +
+ +
+ Whining Queries + + + Each whining 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. + + + + 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. + + + + 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 ). + + + + + When running queries, the whining 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. + + + + + 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. + + + + 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. + + + + + 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! + + +
+ +
+ Saving Your Changes + + + 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. + + + + + 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. + + +
