Software Testing portal

Bug reports and feature requests relating to the MediaWiki software which powers Wikipedia should be filed on Wikimedia's bugzilla. Bugzilla is a bug reporting tool and organization system used by many software projects.

Bugs that are not directly related to the MediaWiki software should be discussed at Wikipedia:Village pump (technical). When in doubt, discuss issues at the village pump before filing a bug on Wikimedia's bugzilla.

Wikimedia's bugzilla was launched in August 2004 to replace the old MediaWiki bug tracker at SourceForge.

[edit] Reporting a bug

You've got a bug, and you're itching to report it. The first thing you should do is search for an existing bug. Someone may have already reported the bug. Searching first helps to prevent duplicates. To be effective, try multiple synonyms and rephrasings of what the bug might have been called.

The next step is to create an account, as accounts on Wikipedia do not carry over into bugzilla. Your email address will be visible on any report you make and on any votes you cast.

Finally, you get to enter your bug! Select the product (usually MediaWiki), and you're ready to go.

[edit] Details

Here are what the fields mean (for MediaWiki):

• Version - for bugs visible on Wikipedia, choose 1.16-svn
• Platform and OS - these usually have no bearing on the actual bug, but it doesn't hurt to leave them specified (if you don't, they are autodetected)
• Component - try to figure out what part of MediaWiki the bug is part of.
• Severity - how severe the bug is. This should not be an opinion on your part, rather, based on these tags:
  • Blocker - blocks development and/or testing work (you probably wouldn't know)
  • Critical - crashes, loss of data (internally, not, say, your edit preview)
  • Major - major loss of function
  • Minor - minor loss of function, or other problem where easy workaround is present
  • Trivial - cosmetic problem like misspelled words or misaligned text
  • Enhancement - request for enhancement (feature requests)
• Assign To - the field will automatically get filled, don't touch it
• CC - this field will add people to a mailing list which notifies users when a bug has been changed. It's generally not a good idea to randomly add people to the CC list (let them do it)
• URL - a specific URL for the bug, if any
• Summary - describe the bug in 60 characters or fewer. Be pithy, be precise, and be concise. A developer should be able to read the summary and say, "Oh, that's what the bug is about." A bad summary is "Wikipedia isn't working!" Remember, people searching for bugs will often search the summary. Make a good impression: the summary should tell the developer whether or not to look into the bug.

[edit] Description

See "Bug Writing Guidelines" on Mozilla's bugzilla

In a description, you should describe anything and everything about the bug. A general template to go about doing this is:

1. An overall description of the bug
2. Steps to reproduce
3. Expected result
4. Actual result
5. Additional information

Keep things to one bug to a report, and if necessary, file multiple bug reports. A good bug report is:

1. Reproducible - if the developer can't reproduce the bug, it'll get marked WORKSFORME or INVALID
2. Specific - make isolating the bug to an area quicker for the developer

[edit] Updates on your bug

You will be emailed with updates on the status of your bug. Sometimes developers may reject, or misunderstand a bug report or feature request and close a report that you think is still valid. If you believe there's still an issue, you can reopen it and try to make a better explanation, or you can take it to the mailing list. If you do not want to get updates on your bug, you can state this in your email preferences.

[edit] Voting

See "Voting" at Wikimedia's bugzilla

Voting is a mechanism that allows you to show which bugs you care about. You can vote for a bug by clicking "Vote for this bug" towards the bottom of the page. You can change your mind later and remove your vote by going to the my votes page.

Note that developers are not obligated to implement a request just because it has a large number of votes.

[edit] Etiquette

See "Bugzilla Etiquette" at Mozilla's bugzilla

Bugzilla is a place to notify developers of bugs and contribute information that would be useful in the fixing of the bugs. It is not a place for advocacy viz. "I REALLY WANT THIS BUG FIXED!" With that in mind, please keep the following rules in mind when using Bugzilla:

• Contribute useful comments; useless comments (i.e. advocacy) decrease the signal to noise ratio
• The developers are under no obligation to fix your bug or add a feature you want.
• No personal abuse: do not make threats like "I will not edit Wikipedia until this bug is fixed"
• Don't mess around with fields unless you are the bug's assignee or you know what you are doing, instead, comment on the suggested change
• Don't whine about WONTFIX decisions
• Applicability varies, but when in doubt, follow the rules

If you see someone not following these rules, politely mention it to them via private email: do not bugspam some more by chastising the user for their conduct publicly.

[edit] Linking to bugs

You can link to bugs using the bugzilla: interwiki prefix. For example, type [[bugzilla:1000]] for bugzilla:1000.

The mediazilla: prefix can be used for linking to any static page in MediaZilla. For example, type [[mediazilla:index.cgi]] for mediazilla:index.cgi.

Also, note that [[bug:1000]] links to the Buginese Wikipedia, not to bugzilla.

[edit] Useful queries

• Search for all enhancement requests
• Reports by number of votes

[edit] Other features

• Bug graphs can be made on the generate table report page.
• Random quotes are shown at the top of the buglist. You can add new ones to the quipslist.
• You can view all new bugs (ones that have not yet been assigned to a developer) on the new bugs list.
• If you use Mozilla or Netscape 6, you can add the bugs page to your sidebar using the link on the main page.
