Using Bugzilla
Introduction This section contains information for end-users of Bugzilla. There is a Bugzilla test installation, called Landfill, which you are welcome to play with (if it's up). However, not all of the Bugzilla installations there will necessarily have all Bugzilla features enabled, and different installations run different versions, so some things may not quite work as this document describes.
Create a Bugzilla Account If you want to use Bugzilla, first you need to create an account. Consult with the administrator responsible for your installation of Bugzilla for the URL you should use to access it. If you're test-driving Bugzilla, use this URL: . Click the Open a new Bugzilla account link, enter your email address and, optionally, your name in the spaces provided, then click Create Account . Within moments, you should receive an email to the address you provided, which contains your login name (generally the same as the email address), and a password. This password is randomly generated, but can be changed to something more memorable. Click the Log In link in the footer at the bottom of the page in your browser, enter your email address and password into the spaces provided, and click Login. You are now logged in. Bugzilla uses cookies to remember you are logged in so, unless you have cookies disabled or your IP address changes, you should not have to log in again.
Anatomy of a Bug The core of Bugzilla is the screen which displays a particular bug. It's a good place to explain some Bugzilla concepts. Bug 1 on Landfill is a good example. Note that the labels for most fields are hyperlinks; clicking them will take you to context-sensitive help on that particular field. Fields marked * may not be present on every installation of Bugzilla. Product and Component: Bugs are divided up by Product and Component, with a Product having one or more Components in it. For example, bugzilla.mozilla.org's "Bugzilla" Product is composed of several Components: Administration: Administration of a Bugzilla installation. Bugzilla-General: Anything that doesn't fit in the other components, or spans multiple components. Creating/Changing Bugs: Creating, changing, and viewing bugs. Documentation: The Bugzilla documentation, including The Bugzilla Guide. Email: Anything to do with email sent by Bugzilla. Installation: The installation process of Bugzilla. Query/Buglist: Anything to do with searching for bugs and viewing the buglists. Reporting/Charting: Getting reports from Bugzilla. User Accounts: Anything about managing a user account from the user's perspective. Saved queries, creating accounts, changing passwords, logging in, etc. User Interface: General issues having to do with the user interface cosmetics (not functionality) including cosmetic issues, HTML templates, etc. Status and Resolution: These define exactly what state the bug is in - from not even being confirmed as a bug, through to being fixed and the fix confirmed by Quality Assurance. The different possible values for Status and Resolution on your installation should be documented in the context-sensitive help for those items. Assigned To: The person responsible for fixing the bug. *URL: A URL associated with the bug, if any. Summary: A one-sentence summary of the problem. *Status Whiteboard: (a.k.a. Whiteboard) A free-form text area for adding short notes and tags to a bug. *Keywords: The administrator can define keywords which you can use to tag and categorise bugs - e.g. The Mozilla Project has keywords like crash and regression. Platform and OS: These indicate the computing environment where the bug was found. Version: The "Version" field is usually used for versions of a product which have been released, and is set to indicate which versions of a Component have the particular problem the bug report is about. Priority: The bug assignee uses this field to prioritise his or her bugs. It's a good idea not to change this on other people's bugs.

eporter: The person who filed the bug. CC list: A list of people who get mail when the bug changes. *Time Tracking: This form can be used for time tracking. To use this feature, you have to be blessed group membership specified by the timetrackinggroup parameter. Orig. Est.: This field shows the original estimated time. Current Est.: This field shows the current estimated time. This number is calculated from Hours Worked and Hours Left. Hours Worked: This field shows the number of hours worked. Hours Left: This field shows the Current Est. - Hours Worked. This value + Hours Worked will become the new Current Est. %Complete: This field shows what percentage of the task is complete. Gain: This field shows the number of hours that the bug is ahead of the Orig. Est.. Deadline: This field shows the deadline for this bug. Attachments: You can attach files (e.g. testcases or patches) to bugs. If there are any attachments, they are listed in this section. Attachments are normally stored in the Bugzilla database, unless they are marked as Big Files, which are stored directly on disk and (unlike attachments kept in the database) may be deleted at some future time. *Dependencies: If this bug cannot be fixed unless other bugs are fixed (depends on), or this bug stops other bugs being fixed (blocks), their numbers are recorded here. *Votes: Whether this bug has any votes. Additional Comments: You can add your two cents to the bug discussion here, if you have something worthwhile to say.
Life Cycle of a Bug The life cycle, also known as work flow, of a bug is currently hardcoded into Bugzilla. contains a graphical repsentation of this life cycle. If you wish to customize this image for your site, the diagram file is available in Dia's native XML format.
Lifecycle of a Bugzilla Bug
Searching for Bugs The Bugzilla Search page is the interface where you can find any bug report, comment, or patch currently in the Bugzilla system. You can play with it here: . The Search page has controls for selecting different possible values for all of the fields in a bug, as described above. For some fields, multiple values can be selected. In those cases, Bugzilla returns bugs where the content of the field matches any one of the selected values. If none is selected, then the field can take any value. Once you've run a search, you can save it as a Saved Search, which appears in the page footer. On the Saved Searches tab of your User Preferences page (the Prefs link in Bugzilla's footer), members of the group defined in the querysharegroup parameter can share such Saved Searches with user groups so that other users may use them. At the same place, you can see Saved Searches other users are sharing, and have them show up in your personal Bugzilla footer along with your own Saved Searches. If somebody is sharing a Search with a group she or he is allowed to assign users to, it will show up in the group's direct members' footers by default.
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 criteria. 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, additional 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")
The bugs listed will be only the bugs where ALL the charts are true.
Bug Lists If you run a search, a list of matching bugs will be returned. The format of the list is configurable. For example, it can be sorted by clicking the column headings. Other useful features can be accessed using the links at the bottom of the list: Long Format: this gives you a large page with a non-editable summary of the fields of each bug. CSV: get the buglist as comma-separated values, for import into e.g. a spreadsheet. RSS get the buglist as an RSS 1.0 feed. Copy this link into your favorite feed reader. If you are using Firefox, you can also save the list as a live bookmark by clicking the live bookmark icon in the status bar. To limit the number of bugs in the feed, add a limit=n parameter to the URL. iCalendar Get the buglist as an iCalendar file. Each bug is represented as a to-do item in the imported calendar. Change Columns: change the bug attributes which appear in the list. Change several bugs at once: If your account is sufficiently empowered, you can make the same change to all the bugs in the list - for example, changing their assignee. Send mail to bug assignees: Sends mail to the assignees of all bugs on the list. Edit Search: If you didn't get exactly the results you were looking for, you can return to the Query page through this link and make small revisions to the query you just made so you get more accurate results. Remember Search As: You can give a search a name and remember it; a link will appear in your page footer giving you quick access to run it again later. If you would like to access the bug list from another program it is often useful to have the list returned in something other than HTML. By adding the ctype=type parameter into the bug list URL you can specify several alternate formats. The supported formats are: Comma Separated Values (ctype=csv), iCalendar (ctype=ics), RDF Site Summary (RSS) 1.0 (ctype=rss), ECMAScript, also known as JavaScript (ctype=js), and finally Resource Description Framework RDF/XML (ctype=rdf).
Filing Bugs Years of bug writing experience has been distilled for your reading pleasure into the Bug Writing Guidelines. While some of the advice is Mozilla-specific, the basic principles of reporting Reproducible, Specific bugs, isolating the Product you are using, the Version of the Product, the Component which failed, the Hardware Platform, and Operating System you were using at the time of the failure go a long way toward ensuring accurate, responsible fixes for the bug that bit you. The procedure for filing a test bug is as follows: Go to Landfill in your browser and click Enter a new bug report. Select a product - any one will do. Fill in the fields. Bugzilla should have made reasonable guesses, based upon your browser, for the "Platform" and "OS" drop-down boxes. If they are wrong, change them. Select "Commit" and send in your bug report. Try to make sure that everything said in the summary is also said in the first comment. Summaries are often updated and this will ensure your original information is easily accessible. You do not need to put "any" or similar strings in the URL field. If there is no specific URL associated with the bug, leave this field blank. If you feel a bug you filed was incorrectly marked as a DUPLICATE of another, please question it in your bug, not the bug it was duped to. Feel free to CC the person who duped it if they are not already CCed.
Patch Viewer Viewing and reviewing patches in Bugzilla is often difficult due to lack of context, improper format and the inherent readability issues that raw patches present. Patch Viewer is an enhancement to Bugzilla designed to fix that by offering increased context, linking to sections, and integrating with Bonsai, LXR and CVS. Patch viewer allows you to: View patches in color, with side-by-side view rather than trying to interpret the contents of the patch. See the difference between two patches. Get more context in a patch. Collapse and expand sections of a patch for easy reading. Link to a particular section of a patch for discussion or review Go to Bonsai or LXR to see more context, blame, and cross-references for the part of the patch you are looking at Create a rawtext unified format diff out of any patch, no matter what format it came from
Viewing Patches in Patch Viewer The main way to view a patch in patch viewer is to click on the "Diff" link next to a patch in the Attachments list on a bug. You may also do this within the edit window by clicking the "View Attachment As Diff" button in the Edit Attachment screen.
Seeing the Difference Between Two Patches To see the difference between two patches, you must first view the newer patch in Patch Viewer. Then select the older patch from the dropdown at the top of the page ("Differences between [dropdown] and this patch") and click the "Diff" button. This will show you what is new or changed in the newer patch.
Getting More Context in a Patch To get more context in a patch, you put a number in the textbox at the top of Patch Viewer ("Patch / File / [textbox]") and hit enter. This will give you that many lines of context before and after each change. Alternatively, you can click on the "File" link there and it will show each change in the full context of the file. This feature only works against files that were diffed using "cvs diff".
Collapsing and Expanding Sections of a Patch To view only a certain set of files in a patch (for example, if a patch is absolutely huge and you want to only review part of it at a time), you can click the "(+)" and "(-)" links next to each file (to expand it or collapse it). If you want to collapse all files or expand all files, you can click the "Collapse All" and "Expand All" links at the top of the page.
Going to Bonsai and LXR To go to Bonsai to get blame for the lines you are interested in, you can click the "Lines XX-YY" link on the section header you are interested in. This works even if the patch is against an old version of the file, since Bonsai stores all versions of the file. To go to LXR, you click on the filename on the file header (unfortunately, since LXR only does the most recent version, line numbers are likely to rot).
Creating a Unified Diff If the patch is not in a format that you like, you can turn it into a unified diff format by clicking the "Raw Unified" link at the top of the page.
Hints and Tips This section distills some Bugzilla tips and best practices that have been developed.
Autolinkification Bugzilla comments are plain text - so typing <U> will produce less-than, U, greater-than rather than underlined text. However, Bugzilla will automatically make hyperlinks out of certain sorts of text in comments. For example, the text "http://www.bugzilla.org" will be turned into a link: . Other strings which get linkified in the obvious manner are: bug 12345 comment 7 bug 23456, comment 53 attachment 4321 mailto:george@example.com george@example.com ftp://ftp.mozilla.org Most other sorts of URL A corollary here is that if you type a bug number in a comment, you should put the word "bug" before it, so it gets autolinkified for the convenience of others.
Quicksearch Quicksearch is a single-text-box query tool which uses metacharacters to indicate what is to be searched. For example, typing "foo|bar" into Quicksearch would search for "foo" or "bar" in the summary and status whiteboard of a bug; adding ":BazProduct" would search only in that product. You can use it to find a bug by its number or its alias, too. You'll find the Quicksearch box in Bugzilla's footer area. On Bugzilla's front page, there is an additional Help link which details how to use it.
Comments If you are changing the fields on a bug, only comment if either you have something pertinent to say, or Bugzilla requires it. Otherwise, you may spam people unnecessarily with bug mail. To take an example: a user can set up their account to filter out messages where someone just adds themselves to the CC field of a bug (which happens a lot.) If you come along, add yourself to the CC field, and add a comment saying "Adding self to CC", then that person gets a pointless piece of mail they would otherwise have avoided. Don't use sigs in comments. Signing your name ("Bill") is acceptable, if you do it out of habit, but full mail/news-style four line ASCII art creations are not.
Attachments Use attachments, rather than comments, for large chunks of ASCII data, such as trace, debugging output files, or log files. That way, it doesn't bloat the bug for everyone who wants to read it, and cause people to receive fat, useless mails. Trim screenshots. There's no need to show the whole screen if you are pointing out a single-pixel problem. Don't attach simple test cases (e.g. one HTML file, one CSS file and an image) as a ZIP file. Instead, upload them in reverse order and edit the referring file so that they point to the attached files. This way, the test case works immediately out of the bug. Bugzilla stores and uses a Content-Type for each attachment (e.g. text/html). To download an attachment as a different Content-Type (e.g. application/xhtml+xml), you can override this using a 'content-type' parameter on the URL, e.g. &content-type=text/plain. If you have a really large attachment, something that does not need to be recorded forever (as most attachments are), you can mark your attachment as a Big File, Assuming the administrator of the installation has enabled this feature. Big Files are stored directly on disk instead of in the database, and can be deleted when it is no longer needed. The maximum size of a Big File is normally larger than the maximum size of a regular attachment.
Dependency Tree On the Dependency tree page linked from each bug page, you can see the dependency relationship from the bug as a tree structure. You can change how much depth to show, and you can hide resolved bugs from this page. You can also collaps/expand dependencies for each bug on the tree view, using the [-]/[+] buttons that appear before its summary. This option is not available for terminal bugs in the tree (that don't have further dependencies).
User Preferences Once you have logged in, you can customise various aspects of Bugzilla via the "Edit prefs" link in the page footer. The preferences are split into three tabs:
Account Preferences On this tab, you can change your basic account information, including your password, email address and real name. For security reasons, in order to change anything on this page you must type your current password into the Password field at the top of the page. If you attempt to change your email address, a confirmation email is sent to both the old and new addresses, with a link to use to confirm the change. This helps to prevent account hijacking.
General Preferences This tab allows you to change several Bugzilla behavior. Field separator character for CSV files - This controls separator character used in CSV formatted Bug List. After changing bugs - This controls which bugs or no bugs are shown in the page after you changed bugs. You can select the bug you've changed this time, or the next bug of the list. Add individual bugs to saved searches - this controls whether you can add individual bugs to saved searches or you can't. When viewing a bug, show comments in this order - This controls the order of comments, you can select below: Initial description, comment 1, comment 2, ... Initial description, last comment, ..., comment 2, comment 1. Initial last comment, ..., comment 2, comment 1, description. Show a quip at the top of each bug list - This controls whether a quip will be shown on the Bug list page or not.
Email Preferences This tab controls the amount of email Bugzilla sends you. The first item on this page is marked Users to watch. When you enter one or more comma-delineated user accounts (usually email addresses) into the text entry box, you will receive a copy of all the bugmail those users are sent (security settings permitting). This powerful functionality enables seamless transitions as developers change projects or users go on holiday. The ability to watch other users may not be available in all Bugzilla installations. If you don't see this feature, and feel that you need it, speak to your administrator. Each user listed in the Users watching you field has you listed in their Users to watch list and can get bugmail according to your relationship to the bug and their Field/recipient specific options setting. In general, users have almost complete control over how much (or how little) email Bugzilla sends them. If you want to receive the maximum amount of email possible, click the Enable All Mail button. If you don't want to receive any email from Bugzilla at all, click the Disable All Mail button. Your Bugzilla administrator can stop a user from receiving bugmail by adding the user's name to the data/nomail file. This is a drastic step best taken only for disabled accounts, as it overrides the user's individual mail preferences. If you'd like to set your bugmail to something besides 'Completely ON' and 'Completely OFF', the Field/recipient specific options table allows you to do just that. The rows of the table define events that can happen to a bug -- things like attachments being added, new comments being made, the priority changing, etc. The columns in the table define your relationship with the bug: Reporter - Where you are the person who initially reported the bug. Your name/account appears in the Reporter: field. Assignee - Where you are the person who has been designated as the one responsible for the bug. Your name/account appears in the Assigned To: field of the bug. QA Contact - You are one of the designated QA Contacts for the bug. Your account appears in the QA Contact: text-box of the bug. CC - You are on the list CC List for the bug. Your account appears in the CC: text box of the bug. Voter - You have placed one or more votes for the bug. Your account appears only if someone clicks on the Show votes for this bug link on the bug. Some columns may not be visible for your installation, depending on your site's configuration. To fine-tune your bugmail, decide the events for which you want to receive bugmail; then decide if you want to receive it all the time (enable the checkbox for every column), or only when you have a certain relationship with a bug (enable the checkbox only for those columns). For example: if you didn't want to receive mail when someone added themselves to the CC list, you could uncheck all the boxes in the CC Field Changes line. As another example, if you never wanted to receive email on bugs you reported unless the bug was resolved, you would un-check all boxes in the Reporter column except for the one on the The bug is resolved or verified row. Bugzilla adds the X-Bugzilla-Reason header to all bugmail it sends, describing the recipient's relationship (AssignedTo, Reporter, QAContact, CC, or Voter) to the bug. This header can be used to do further client-side filtering. Two items not in the table (Email me when someone asks me to set a flag and Email me when someone sets a flag I asked for) define how you want to receive bugmail with regards to flags. Their use is quite straightforward; enable the checkboxes if you want Bugzilla to send you mail under either of the above conditions. By default, Bugzilla sends out email regardless of who made the change... even if you were the one responsible for generating the email in the first place. If you don't care to receive bugmail from your own changes, check the box marked Only email me reports of changes made by other people.
Permissions This is a purely informative page which outlines your current permissions on this installation of Bugzilla - what product groups you are in, and whether you can edit bugs or perform various administration functions.
Reports and Charts As well as the standard buglist, Bugzilla has two more ways of viewing sets of bugs. These are the reports (which give different views of the current state of the database) and charts (which plot the changes in particular sets of bugs over time.)
Reports A report is a view of the current state of the bug database. You can run either an HTML-table-based report, or a graphical line/pie/bar-chart-based one. The two have different pages to define them, but are close cousins - once you've defined and viewed a report, you can switch between any of the different views of the data at will. Both report types are based on the idea of defining a set of bugs using the standard search interface, and then choosing some aspect of that set to plot on the horizontal and/or vertical axes. You can also get a form of 3-dimensional report by choosing to have multiple images or tables. So, for example, you could use the search form to choose "all bugs in the WorldControl product", and then plot their severity against their component to see which component had had the largest number of bad bugs reported against it. Once you've defined your parameters and hit "Generate Report", you can switch between HTML, CSV, Bar, Line and Pie. (Note: Pie is only available if you didn't define a vertical axis, as pie charts don't have one.) The other controls are fairly self-explanatory; you can change the size of the image if you find text is overwriting other text, or the bars are too thin to see.
Charts A chart is a view of the state of the bug database over time. Bugzilla currently has two charting systems - Old Charts and New Charts. Old Charts have been part of Bugzilla for a long time; they chart each status and resolution for each product, and that's all. They are deprecated, and going away soon - we won't say any more about them. New Charts are the future - they allow you to chart anything you can define as a search. Both charting forms require the administrator to set up the data-gathering script. If you can't see any charts, ask them whether they have done so. An individual line on a chart is called a data set. All data sets are organised into categories and subcategories. The data sets that Bugzilla defines automatically use the Product name as a Category and Component names as Subcategories, but there is no need for you to follow that naming scheme with your own charts if you don't want to. Data sets may be public or private. Everyone sees public data sets in the list, but only their creator sees private data sets. Only administrators can make data sets public. No two data sets, even two private ones, can have the same set of category, subcategory and name. So if you are creating private data sets, one idea is to have the Category be your username.
Creating Charts You create a chart by selecting a number of data sets from the list, and pressing Add To List for each. In the List Of Data Sets To Plot, you can define the label that data set will have in the chart's legend, and also ask Bugzilla to Sum a number of data sets (e.g. you could Sum data sets representing RESOLVED, VERIFIED and CLOSED in a particular product to get a data set representing all the resolved bugs in that product.) If you've erroneously added a data set to the list, select it using the checkbox and click Remove. Once you add more than one data set, a "Grand Total" line automatically appears at the bottom of the list. If you don't want this, simply remove it as you would remove any other line. You may also choose to plot only over a certain date range, and to cumulate the results - that is, to plot each one using the previous one as a baseline, so the top line gives a sum of all the data sets. It's easier to try than to explain :-) Once a data set is in the list, one can also perform certain actions on it. For example, one can edit the data set's parameters (name, frequency etc.) if it's one you created or if you are an administrator. Once you are happy, click Chart This List to see the chart.
Creating New Data Sets You may also create new data sets of your own. To do this, click the "create a new data set" link on the Create Chart page. This takes you to a search-like interface where you can define the search that Bugzilla will plot. At the bottom of the page, you choose the category, sub-category and name of your new data set. If you have sufficient permissions, you can make the data set public, and reduce the frequency of data collection to less than the default seven days.
Flags A flag is a kind of status that can be set on bugs or attachments to indicate that the bugs/attachments are in a certain state. Each installation can define its own set of flags that can be set on bugs or attachments. If your installation has defined a flag, you can set or unset that flag, and if your administrator has enabled requesting of flags, you can submit a request for another user to set the flag. To set a flag, select either "+" or "-" from the drop-down menu next to the name of the flag in the "Flags" list. The meaning of these values are flag-specific and thus cannot be described in this documentation, but by way of example, setting a flag named "review" to "+" may indicate that the bug/attachment has passed review, while setting it to "-" may indicate that the bug/attachment has failed review. To unset a flag, click its drop-down menu and select the blank value. If your administrator has enabled requests for a flag, request a flag by selecting "?" from the drop-down menu and then entering the username of the user you want to set the flag in the text field next to the menu. A set flag appears in bug reports and on "edit attachment" pages with the abbreviated username of the user who set the flag prepended to the flag name. For example, if Jack sets a "review" flag to "+", it appears as Jack: review [ + ] A requested flag appears with the user who requested the flag prepended to the flag name and the user who has been requested to set the flag appended to the flag name within parentheses. For example, if Jack asks Jill for review, it appears as Jack: review [ ? ] (Jill). You can browse through open requests made of you and by you by selecting 'My Requests' from the footer. You can also look at open requests limited by other requesters, requestees, products, components, and flag names from this page. Note that you can use '-' for requestee to specify flags with 'no requestee' set.
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.
