### 1. General Questions

A.1.1. Where can I find information about Bugzilla?

You can stay up-to-date with the latest Bugzilla information at http://www.bugzilla.org/

A.1.2. What license is Bugzilla distributed under?

Bugzilla is covered by the Mozilla Public License. See details at http://www.mozilla.org/MPL/

A.1.3. How do I get commercial support for Bugzilla?

http://bugzilla.org/consulting.html is a list of people and companies who have asked us to list them as consultants for Bugzilla.

www.collab.net offers Bugzilla as part of their standard offering to large projects. They do have some minimum fees that are pretty hefty, and generally aren't interested in small projects.

There are several experienced Bugzilla hackers on the mailing list/newsgroup who are willing to make themselves available for generous compensation. Try sending a message to the mailing list asking for a volunteer.

A.1.4. What major companies or projects are currently using Bugzilla for bug-tracking?

There are dozens of major companies with public Bugzilla sites to track bugs in their products. A few include:

Netscape/AOL
Mozilla.org
NASA
Red Hat Software
SuSe Corp
The Horde Project
AbiSource
Real Time Enterprises, Inc
Eggheads.org
Strata Software
RockLinux
Creative Labs (makers of SoundBlaster)
The Apache Foundation
The Gnome Foundation
Ximian
Linux-Mandrake

Suffice to say, there are more than enough huge projects using Bugzilla that we can safely say it's extremely popular.

A.1.5. Who maintains Bugzilla?

A core team, led by Dave Miller (justdave@bugzilla.org).

A.1.6. How does Bugzilla stack up against other bug-tracking databases?

We can't find any head-to-head comparisons of Bugzilla against other defect-tracking software. If you know of one, please get in touch. However, from the author's personal experience with other bug-trackers, Bugzilla offers superior performance on commodity hardware, better price (free!), more developer- friendly features (such as stored queries, email integration, and platform independence), improved scalability, open source code, greater flexibility, and superior ease-of-use.

If you happen to be a commercial bug-tracker vendor, please step forward with a list of advantages your product has over Bugzilla. We'd be happy to include it in the "Competitors" section.

A.1.7. Why doesn't Bugzilla offer this or that feature or compatibility with this other tracking software?

It may be that the support has not been built yet, or that you have not yet found it. Bugzilla is making tremendous strides in usability, customizability, scalability, and user interface. It is widely considered the most complete and popular open-source bug-tracking software in existence.

That doesn't mean it can't use improvement! You can help the project along by either hacking a patch yourself that supports the functionality you require, or else submitting a "Request for Enhancement" (RFE) using the bug submission interface at bugzilla.mozilla.org.

A.1.8. Why MySQL? I'm interested in seeing Bugzilla run on Oracle/Sybase/Msql/PostgreSQL/MSSQL.

MySQL was originally chosen because it is free, easy to install, and was available for the hardware Netscape intended to run it on.

There is currently work in progress to make Bugzilla work on PostgreSQL and Sybase in the default distribution. You can track the progress of these initiatives in bugs 98304 and 173130 respectively.

Once both of these are done, adding support for additional database servers should be trivial.

A.1.9. Why do the scripts say `/usr/bonsaitools/bin/perl` instead of `/usr/bin/perl` or something else?

Mozilla.org used `/usr/bonsaitools/bin/perl`, because originally Terry wanted a place to put a version of Perl and other tools that was strictly under his control.

| This convention was abonded during the 2.17 development cycle so it will no longer be an issue when 2.18 comes out.

A.1.10. Is there an easy way to change the Bugzilla cookie name?

At present, no.

### 2. Managerial Questions

| Questions likely to be asked by managers. :-)

A.2.1. Is Bugzilla web-based, or do you have to have specific software or a specific operating system on your machine?

It is web and e-mail based. You can edit bugs by sending specially formatted email to a properly configured Bugzilla, or control via the web.

A.2.2. Can Bugzilla integrate with Perforce (SCM software)?

Yes! You can find more information elsewhere in "The Bugzilla Guide" in the "Integration with Third-Party Products" section.

A.2.3. Does Bugzilla allow the user to track multiple projects?

Absolutely! You can track any number of Products that can each be composed of any number of Components.

| There are only 55 groups available in version 2.16 of Bugzilla. If you are using product groups, this will also limit the number of products you can have. This limit does not exist in the current 2.17 development releases and will not exist in 2.18.

A.2.4. If I am on many projects, and search for all bugs assigned to me, will Bugzilla list them for me and allow me to sort by project, severity etc?

Yes.

A.2.5. Does Bugzilla allow attachments (text, screenshots, URLs etc)? If yes, are there any that are NOT allowed?

Yes - any sort of attachment is allowed, although administrators can configure a maximum size. Bugzilla gives the user the option of either using the MIME-type supplied by the browser, choosing from a pre-defined list or manually typing any arbitrary MIME-type.

A.2.6. Does Bugzilla allow us to define our own priorities and levels? Do we have complete freedom to change the labels of fields and format of them, and the choice of acceptable values?

Yes. However, modifying some fields, notably those related to bug progression states, also require adjusting the program logic to compensate for the change.

There is no GUI for adding fields to Bugzilla at this time. You can follow development of this feature at http://bugzilla.mozilla.org/show_bug.cgi?id=91037.

A.2.7. Does Bugzilla provide any reporting features, metrics, graphs, etc? You know, the type of stuff that management likes to see. :)

Yes. Look at http://bugzilla.mozilla.org/reports.cgi for samples of what Bugzilla can do in reporting and graphing.

If you can not get the reports you want from the included reporting scripts, it is possible to hook up a professional reporting package such as Crystal Reports using ODBC. If you choose to do this, beware that giving direct access to the database does contain some security implications. Even if you give read-only access to the bugs database it will bypass the secure bugs features of Bugzilla.

| Bugzilla's current development versions can do a lot more in the way of reporting. To see examples, check out http://bugzilla.mozilla.org/report.cgi.

A.2.8. Is there email notification and if so, what do you see when you get an email?

Email notification is user-configurable. By default, the bug id and Summary of the bug report accompany each email notification, along with a list of the changes made.

A.2.9. Can email notification be set up to send to multiple people, some on the To List, CC List, BCC List etc?

Yes.

A.2.10. Do users have to have any particular type of email application?

Bugzilla email is sent in plain text, the most compatible mail format on the planet.

| If you decide to use the bugzilla_email integration features to allow Bugzilla to record responses to mail with the associated bug, you may need to caution your users to set their mailer to "respond to messages in the format in which they were sent". For security reasons Bugzilla ignores HTML tags in comments, and if a user sends HTML-based email into Bugzilla the resulting comment looks downright awful.

A.2.11. Does Bugzilla allow data to be imported and exported? If I had outsiders write up a bug report using a MS Word bug template, could that template be imported into "matching" fields? If I wanted to take the results of a query and export that data to MS Excel, could I do that?

Bugzilla can only output buglists as HTML in version 2.16. There are other formats available (CSV and RDF) in the newer development versions.

Bugzilla can export bugs using `xml.cgi` with either a bug number or list of bug numbers.

Currently the only script included with Bugzilla that can import data is `importxml.pl` which is intended to be used for importing the data generated by `xml.cgi` in association with bug moving. Any other use is left as an exercise for the user.

There are also scripts included in the `contrib/` directory for using e-mail to import information into Bugzilla, but these scripts are not currently supported and included for educational purposes.

A.2.12. Has anyone converted Bugzilla to another language to be used in other countries? Is it localizable?

Yes. For more information including available translated templates, see http://www.bugzilla.org/download.html#localizations. The admin interfaces are still not included in these translated templates and is therefore still English only. Also, there may be issues with the charset not being declared. See bug 126226 for more information.

A.2.13. Can a user create and save reports? Can they do this in Word format? Excel format?

Yes. No. Not in 2.16.

A.2.14. Does Bugzilla have the ability to search by word, phrase, compound search?

You have no idea. Bugzilla's query interface, particularly with the advanced Boolean operators, is incredibly versatile.

A.2.15. Does Bugzilla provide record locking when there is simultaneous access to the same bug? Does the second person get a notice that the bug is in use or how are they notified?

Bugzilla does not lock records. It provides mid-air collision detection, and offers the offending user a choice of options to deal with the conflict.

A.2.16. Are there any backup features provided?

MySQL, the database back-end for Bugzilla, allows hot-backup of data. You can find strategies for dealing with backup considerations at http://www.mysql.com/doc/B/a/Backup.html

A.2.17. Can users be on the system while a backup is in progress?

Yes. However, commits to the database must wait until the tables are unlocked. Bugzilla databases are typically very small, and backups routinely take less than a minute.

A.2.18. How can I update the code and the database using CVS?

1. Make a backup of both your Bugzilla directory and the database. For the Bugzilla directory this is as easy as doing cp -rp bugzilla bugzilla.bak. For the database, there's a number of options - see the MySQL docs and pick the one that fits you best (the easiest is to just make a physical copy of the database on the disk, but you have to have the database server shut down to do that without risking dataloss).

2. Make the Bugzilla directory your current directory.

3. Use cvs -q update -AdP if you want to update to the tip or cvs -q update -dP -rTAGNAME if you want a specific version (in that case you'll have to replace TAGNAME with a CVS tag name such as BUGZILLA-2_16_5).

   If you've made no local changes, this should be very clean. If you have made local changes, then watch the cvs output for C results. If you get any lines that start with a C it means there were conflicts between your local changes and what's in CVS. You'll need to fix those manually before continuing.

4. After resolving any conflicts that the cvs update operation generated, running ./checksetup.pl will take care of updating the database for you as well as any other changes required for the new version to operate.

   | Once you run checksetup.pl, the only way to go back is to restore the database backups. You can't "downgrade" the system cleanly under most circumstances.

A.2.19. What type of human resources are needed to be on staff to install and maintain Bugzilla? Specifically, what type of skills does the person need to have? I need to find out if we were to go with Bugzilla, what types of individuals would we need to hire and how much would that cost vs buying an "Out-of-the-Box" solution.

If Bugzilla is set up correctly from the start, continuing maintenance needs are minimal and can be done easily using the web interface.

Commercial Bug-tracking software typically costs somewhere upwards of $20,000 or more for 5-10 floating licenses. Bugzilla consultation is available from skilled members of the newsgroup. Simple questions are answered there and then.

A.2.20. What time frame are we looking at if we decide to hire people to install and maintain the Bugzilla? Is this something that takes hours or weeks to install and a couple of hours per week to maintain and customize or is this a multi-week install process, plus a full time job for 1 person, 2 people, etc?

It all depends on your level of commitment. Someone with much Bugzilla experience can get you up and running in less than a day, and your Bugzilla install can run untended for years. If your Bugzilla strategy is critical to your business workflow, hire somebody with reasonable UNIX or Perl skills to handle your process management and bug-tracking maintenance & customization.

A.2.21. Is there any licensing fee or other fees for using Bugzilla? Any out-of-pocket cost other than the bodies needed as identified above?

No. MySQL asks, if you find their product valuable, that you purchase a support contract from them that suits your needs.

A.2.22. Why do users have to log in every time they access a page? This affects everyone who accesses my Bugzilla. (If this only affects some of your users, see the next FAQ item.)

The most-likely cause is that the "cookiepath" parameter is not set correctly in the Bugzilla configuration. You can change this (if you're a Bugzilla administrator) from the editparams.cgi page via the web.

The value of the cookiepath parameter should be the actual directory containing your Bugzilla installation, as seen by the end-user's web browser. Leading and trailing slashes are mandatory. You can also set the cookiepath to any directory which is a parent of the Bugzilla directory (such as '/', the root directory). But you can't put something that isn't at least a partial match or it won't work. What you're actually doing is restricting the end-user's browser to sending the cookies back only to that directory.

How do you know if you want your specific Bugzilla directory or the whole site?

If you have only one Bugzilla running on the server, and you don't mind having other applications on the same server with it being able to see the cookies (you might be doing this on purpose if you have other things on your site that share authentication with Bugzilla), then you'll want to have the cookiepath set to "/", or to a sufficiently-high enough directory that all of the involved apps can see the cookies.

Examples:

> urlbase is http://bugzilla.mozilla.org/
> cookiepath is /
> urlbase is http://tools.mysite.tld/bugzilla/
> but you have http://tools.mysite.tld/someotherapp/ which shares
> authentication with your Bugzilla
> cookiepath is /

On the other hand, if you have more than one Bugzilla running on the server (some people do - we do on landfill) then you need to have the cookiepath restricted enough so that the different Bugzillas don't confuse their cookies with one another.

Examples:

> urlbase is http://landfill.bugzilla.org/bugzilla-tip/
> cookiepath is /bugzilla-tip/
> urlbase is http://landfill.bugzilla.org/bugzilla-2.16-branch/
> cookiepath is /bugzilla-2.16-branch/

If you had cookiepath set to / at any point in the past and need to set it to something more restrictive (i.e. /bugzilla/), you can safely do this without requiring users to delete their Bugzilla-related cookies in their browser (this is true starting with Bugzilla 2.17.7 and Bugzilla 2.16.5).

A.2.23. Why do users have to log in every time they access a page? This only seems to affect some of my Bugzilla's users, others stay logged in.

First, make sure cookies are enabled in the user's browser.

If that doesn't fix the problem, it may be that the user's ISP implements a rotating proxy server. This causes the user's effective IP address (the address which the Bugzilla server perceives him coming from) to change periodically. Since Bugzilla cookies are tied to a specific IP address, each time the effective address changes, the user will have to log in again.

In newer versions of Bugzilla (2.17.1 and later) there is a parameter called "loginnetmask", which you can use to set the number of bits of the user's IP address to require to be matched when authenticating the cookies. If you set this to something less than 32, then the user will be given a checkbox for "Restrict this login to my IP address" on the login screen, which defaults to checked. If they leave the box checked, Bugzilla will behave the same as it did before, requiring an exact match on their IP address to remain logged in. If they uncheck the box, then only the left side of their IP address (up to the number of bits you specified in the parameter) has to match to remain logged in.

### 3. Bugzilla Security

A.3.1. How do I completely disable MySQL security if it's giving me problems (I've followed the instructions in the installation section of this guide)?

Run MySQL like this: "mysqld --skip-grant-tables". Please remember this makes MySQL as secure as taping a $100 to the floor of a football stadium bathroom for safekeeping.

A.3.2. Are there any security problems with Bugzilla?

The Bugzilla code has undergone a reasonably complete security audit, and user-facing CGIs run under Perl's taint mode. However, it is recommended that you closely examine permissions on your Bugzilla installation, and follow the recommended security guidelines found in The Bugzilla Guide.

A.3.3. I've implemented the security fixes mentioned in Chris Yeh's security advisory of 5/10/2000 advising not to run MySQL as root, and am running into problems with MySQL no longer working correctly.

This is a common problem, related to running out of file descriptors. Simply add "ulimit -n unlimited" to the script which starts mysqld.

### 4. Bugzilla Email

A.4.1. I have a user who doesn't want to receive any more email from Bugzilla. How do I stop it entirely for this user?

The user should be able to set this in user email preferences (uncheck all boxes) or you can add their email address to the `data/nomail` file.

A.4.2. I'm evaluating/testing Bugzilla, and don't want it to send email to anyone but me. How do I do it?

Edit the "newchangedmail" Param. Replace "To:" with "X-Real-To:", replace "Cc:" with "X-Real-CC:", and add a "To: <youremailaddress>".

A.4.3. I want whineatnews.pl to whine at something more, or other than, only new bugs. How do I do it?

Try Klaas Freitag's excellent patch for "whineatassigned" functionality. You can find it at http://bugzilla.mozilla.org/show_bug.cgi?id=6679. This patch is against an older version of Bugzilla, so you must apply the diffs manually.

A.4.4. I don't like/want to use Procmail to hand mail off to bug_email.pl. What alternatives do I have?

You can call bug_email.pl directly from your aliases file, with an entry like this:

> bugzilla-daemon: "|/usr/local/bin/bugzilla/contrib/bug_email.pl"

However, this is fairly nasty and subject to problems; you also need to set up your smrsh (sendmail restricted shell) to allow it. In a pinch, though, it can work.

A.4.5. How do I set up the email interface to submit/change bugs via email?

You can find an updated README.mailif file in the contrib/ directory of your Bugzilla distribution that walks you through the setup.

A.4.6. Email takes FOREVER to reach me from Bugzilla -- it's extremely slow. What gives?

If you are using an alternate Mail Transport Agent (MTA other than sendmail), make sure the options given in the "processmail" and other scripts for all instances of "sendmail" are correct for your MTA.

If you are using Sendmail, try enabling "sendmailnow" in editparams.cgi. If you are using Postfix, you will also need to enable "sendmailnow".

A.4.7. How come email from Bugzilla changes never reaches me?

Double-check that you have not turned off email in your user preferences. Confirm that Bugzilla is able to send email by visiting the "Log In" link of your Bugzilla installation and clicking the "Email me a password" button after entering your email address.

If you never receive mail from Bugzilla, chances you do not have sendmail in "/usr/lib/sendmail". Ensure sendmail lives in, or is symlinked to, "/usr/lib/sendmail".

### 5. Bugzilla Database

A.5.1. I've heard Bugzilla can be used with Oracle?

Red Hat's old version of Bugzilla (based on 2.8) worked on Oracle. Red Hat's newer version (based on 2.17.1 and soon to be merged into the main distribution) runs on PostgreSQL. At this time we know of no recent ports of Bugzilla to Oracle but do intend to support it in the future (possibly the 2.20 time-frame).

A.5.2. I think my database might be corrupted, or contain invalid entries. What do I do?

Run the "sanity check" utility (`./sanitycheck.cgi` in the Bugzilla_home directory) from your web browser to see! If it finishes without errors, you're probably OK. If it doesn't come back OK (i.e. any red letters), there are certain things Bugzilla can recover from and certain things it can't. If it can't auto-recover, I hope you're familiar with mysqladmin commands or have installed another way to manage your database. Sanity Check, although it is a good basic check on your database integrity, by no means is a substitute for competent database administration and avoiding deletion of data. It is not exhaustive, and was created to do a basic check for the most common problems in Bugzilla databases.

A.5.3. I want to manually edit some entries in my database. How?

There is no facility in Bugzilla itself to do this. It's also generally not a smart thing to do if you don't know exactly what you're doing. However, if you understand SQL you can use the mysql command line utility to manually insert, delete and modify table information. There are also more intuitive GUI clients available. Personal favorites of the Bugzilla team are phpMyAdmin and MySQL Control Center.

A.5.4. I think I've set up MySQL permissions correctly, but Bugzilla still can't connect.

Try running MySQL from its binary: "mysqld --skip-grant-tables". This will allow you to completely rule out grant tables as the cause of your frustration. If this Bugzilla is able to connect at this point then you need to check that you have granted proper permission to the user password combo defined in `localconfig`.

| Running MySQL with this command line option is very insecure and should only be done when not connected to the external network as a troubleshooting step.

A.5.5. How do I synchronize bug information among multiple different Bugzilla databases?

Well, you can synchronize or you can move bugs. Synchronization will only work one way -- you can create a read-only copy of the database at one site, and have it regularly updated at intervals from the main database.

MySQL has some synchronization features builtin to the latest releases. It would be great if someone looked into the possibilities there and provided a report to the newsgroup on how to effectively synchronize two Bugzilla installations.

If you simply need to transfer bugs from one Bugzilla to another, checkout the "move.pl" script in the Bugzilla distribution.

### 6. Bugzilla and Win32

A.6.1. What is the easiest way to run Bugzilla on Win32 (Win98+/NT/2K)?

Remove Windows. Install Linux. Install Bugzilla. The boss will never know the difference.

A.6.2. Is there a "Bundle::Bugzilla" equivalent for Win32?

Not currently. Bundle::Bugzilla enormously simplifies Bugzilla installation on UNIX systems. If someone can volunteer to create a suitable PPM bundle for Win32, it would be appreciated.

A.6.3. CGI's are failing with a "something.cgi is not a valid Windows NT application" error. Why?

Depending on what Web server you are using, you will have to configure the Web server to treat *.cgi files as CGI scripts. In IIS, you do this by adding *.cgi to the App Mappings with the <path>\perl.exe %s %s as the executable.

Microsoft has some advice on this matter, as well:

> "Set application mappings. In the ISM, map the extension for the script file(s) to the executable for the script interpreter. For example, you might map the extension .py to Python.exe, the executable for the Python script interpreter. Note For the ActiveState Perl script interpreter, the extension .pl is associated with PerlIS.dll by default. If you want to change the association of .pl to perl.exe, you need to change the application mapping. In the mapping, you must add two percent (%) characters to the end of the pathname for perl.exe, as shown in this example: c:\perl\bin\perl.exe %s %s"

A.6.4. I'm having trouble with the perl modules for NT not being able to talk to to the database.

Your modules may be outdated or inaccurate. Try:

1. Hitting http://www.activestate.com/ActivePerl

2. Download ActivePerl

3. Go to your prompt

4. Type 'ppm'

5. `PPM>` install DBI DBD-mysql GD

I reckon TimeDate and Data::Dumper come with the activeperl. You can check the ActiveState site for packages for installation through PPM. http://www.activestate.com/Packages/

### 7. Bugzilla Usage

A.7.1. How do I change my user name (email address) in Bugzilla?

New in 2.16 - go to the Account section of the Preferences. You will be emailed at both addresses for confirmation.

A.7.2. The query page is very confusing. Isn't there a simpler way to query?

The interface was simplified by a UI designer for 2.16. Further suggestions for improvement are welcome, but we won't sacrifice power for simplicity.

A.7.3. I'm confused by the behavior of the "accept" button in the Show Bug form. Why doesn't it assign the bug to me when I accept it?

The current behavior is acceptable to bugzilla.mozilla.org and most users. You have your choice of patches to change this behavior, however.

Add a "and accept bug" radio button
"Accept" button automatically assigns to you

Note that these patches are somewhat dated. You will need to apply them manually.

A.7.4. I can't upload anything into the database via the "Create Attachment" link. What am I doing wrong?

The most likely cause is a very old browser or a browser that is incompatible with file upload via POST. Download the latest Netscape, Microsoft, or Mozilla browser to handle uploads correctly.

A.7.5. How do I change a keyword in Bugzilla, once some bugs are using it?

In the Bugzilla administrator UI, edit the keyword and it will let you replace the old keyword name with a new one. This will cause a problem with the keyword cache. Run sanitycheck.cgi to fix it.

A.7.6. Why can't I close bugs from the "Change Several Bugs at Once" page?

The logic flow currently used is RESOLVED, then VERIFIED, then CLOSED. You can mass-CLOSE bugs from the change several bugs at once page. but, every bug listed on the page has to be in VERIFIED state before the control to do it will show up on the form. You can also mass-VERIFY, but every bug listed has to be RESOLVED in order for the control to show up on the form. The logic behind this is that if you pick one of the bugs that's not VERIFIED and try to CLOSE it, the bug change will fail miserably (thus killing any changes in the list after it while doing the bulk change) so it doesn't even give you the choice.

### 8. Bugzilla Hacking

A.8.1. What bugs are in Bugzilla right now?

Try this link to view current bugs or requests for enhancement for Bugzilla.

You can view bugs marked for 2.18 release here. This list includes bugs for the 2.18 release that have already been fixed and checked into CVS. Please consult the Bugzilla Project Page for details on how to check current sources out of CVS so you can have these bug fixes early!

A.8.2. How can I change the default priority to a null value? For instance, have the default priority be "---" instead of "P2"?

This is well-documented here: http://bugzilla.mozilla.org/show_bug.cgi?id=49862. Ultimately, it's as easy as adding the "---" priority field to your localconfig file in the appropriate area, re-running checksetup.pl, and then changing the default priority in your browser using "editparams.cgi".

A.8.3. What's the best way to submit patches? What guidelines should I follow?

1. Enter a bug into bugzilla.mozilla.org for the "Bugzilla" product.

2. Upload your patch as a unified diff (having used "diff -u" against the current sources checked out of CVS), or new source file by clicking "Create a new attachment" link on the bug page you've just created, and include any descriptions of database changes you may make, into the bug ID you submitted in step #1. Be sure and click the "Patch" checkbox to indicate the text you are sending is a patch!

3. Announce your patch and the associated URL (http://bugzilla.mozilla.org/show_bug.cgi?id=XXXXXX) for discussion in the newsgroup (netscape.public.mozilla.webtools). You'll get a really good, fairly immediate reaction to the implications of your patch, which will also give us an idea how well-received the change would be.

4. If it passes muster with minimal modification, the person to whom the bug is assigned in Bugzilla is responsible for seeing the patch is checked into CVS.

5. Bask in the glory of the fact that you helped write the most successful open-source bug-tracking software on the planet :)
