MediaWiki extension for Bugzilla

This is a MediaWiki extension that provides read-only access to the Bugzilla REST API

Please note that there are still big outstanding bugs!

Requirements

• MediaWiki 1.17 or above.
• For charting, requires gd

Installation

These directions assume your MediaWiki installation is at /var/lib/mediawiki. Please substitute your installation path if it is different

1. Install the requirements above
2. Check the project out into /path/to/your/mediawiki/extensions/Bugzilla
3. Edit /path/to/your/mediawiki/LocalSettings.php and add require_once("$IP/extensions/Bugzilla/Bugzilla.php"); and change/override any configuration variables. Current configuration variables and their defaults can be found at the end of Bugzilla.php

Usage

You use this extension in this way:

<bugzilla>
    (JSON REST API query key/value pairs)
</bugzilla>

By default, it will output a colored table:

Note that the wiki tag name defaults to "bugzilla" but is configurable by the administrator.

Options

Valid bugzilla tag options are:

• type: "bug" or "count" (defaults to bug)
• For type bug:
  • display: "table" or "list" or "count" (defaults to table)
• For type count:
  • display: "bar" or "pie"
  • size: "small", medium" or "large" (defaults to large)
• stats: "show" or "hide" (defaults to "show")

Examples

All P1 bugs in the Bugzilla product:

<bugzilla>
    {
        "product": "Bugzilla",
        "priority":"P1"
    }
</bugzilla>

All new bugs flagged as uiwanted in the whiteboard:

<bugzilla>
	{
	    "whiteboard": "uiwanted",
	    "status": "NEW"
    }
</bugzilla>

All bugs in the bugzilla.org component that were resolved in 2011, with the stats summary hidden:

<bugzilla stats="hide">
    {
        "component": "bugzilla.org",
        "changed_after": "2011-01-01",
        "changed_before": "2011-12-31",
        "changed_field": "status",
        "changed_field_to": "resolved"
    }
</bugzilla>

Some commonly used query parameters are:

• id
• component
• product
• status
• resolution
• keywords
• whiteboard
• target_milestone
• version
• changed_after
• changed_before

For more details on how to query in various ways, see the documentation for the Bugzilla REST API

Configurable fields/columns

Specify fields in the "include_fields" setting of BZ REST API options as you normally would. Mediawiki-bugzilla will then a) only fetch those fields and b) display those columns.

<bugzilla>
{
    "whiteboard": "[mediawiki-bugzilla]",
    "include_fields": ["id", "summary", "whiteboard", "status", "resolution"]
}
</bugzilla>

Charting

There is also some support for charting:

<bugzilla type="count" display="bar">
    {
        "whiteboard": "[snappy:p1]",
        "x_axis_field": "status"
    }
</bugzilla>

Screenshot of the above:

<bugzilla type="count" display="pie">
{
    "whiteboard": "[mediawiki-bugzilla]",
    "x_axis_field": "status"
}
</bugzilla>
<bugzilla type="count" display="pie" size="medium">
{
    "whiteboard": "[mediawiki-bugzilla]",
    "x_axis_field": "status"
}
</bugzilla>
<bugzilla type="count" display="pie" size="small">
{
    "whiteboard": "[mediawiki-bugzilla]",
    "x_axis_field": "status"
}
</bugzilla>

Screenshot of the above:

Limitations

• This extension (by design) is read-only
• This extension currently queries as a public (not logged in) user
• Charts are fairly hardcoded and don't work in many cases

Known Issues

• The size attribute only works on pie charts
• Rendering a page with an uncached query can take a bit
• Large queries may exceed the allocated memory causing a blank page to be displayed. In this case you can recover by editing the page as follows: If your wiki page has the URL https://wiki.mozilla.org/PagePath/PageTitle The URL to edit your page is https://wiki.mozilla.org/index.php?title=PagePath/PageTitle&action=edit
