This page is a translated version of the page Extension:DataDump and the translation is 2% complete.

The DataDump extension allows users to request and generate database dumps. Other types of dumps, such as image dumps, can be configured in the extension. This allows for easy dumping without the need for system administrator intervention.

For reporting an issue or a bug, please use Miraheze Phorge. See here for the workboard.

Installation

下载文件，并将其放置在您extensions/文件夹中的DataDump目录内。
請新增下列代码到您的LocalSettings.php 文件的底部：
```

請运行更新脚本，它将自动创建此扩展所必须的数据库表。
Configure as required.
完成 – 請导航至您的wiki上的Special:Version，以验证此扩展已成功安装。

Configuration

parameter	default	comment
`$wgDataDump`	`[]`	This config defines how dumps are generated and which types of dumps there are.
`$wgDataDumpDirectory`	`false`	This config defines the directory where to store the dumps.
`$wgDataDumpDisableGenerate`	`false`	This config determines whether DataDump should be disabled or not.
`$wgDataDumpFileBackend`	`false`	This config defines backend to use ($wgFileBackends)
`$wgDataDumpInfo`	`""`	This config defines the information displayed atop Special:DataDump.

Permissions

DataDump provides three permissions. These allow you some granularity when it comes to configuring DataDump.

You are not restricted to only using these permissions to restrict who can download, view, or delete dumps. You can also use other permissions available on the wiki.

permission	comment
`generate-dump`	Allows users to generate database dumps
`view-dump`	Allows users to view dumps
`delete-dump`	Allows users to delete dumps

Example

This is an example of how to set up the configuration. You can tailor it to your specific needs:

$wgDataDumpDirectory = "/var/backups/${wgDBname}/";

$wgDataDump = [
    'xml' => [
        'file_ending' => '.xml.gz',
        'generate' => [
            'type' => 'mwscript',
            'script' => "$IP/maintenance/dumpBackup.php",
            'options' => [
                '--full',
                '--output',
                "gzip:${wgDataDumpDirectory}" . '${filename}',
            ],
        ],
        'limit' => 1,
        'permissions' => [
            'view' => 'view-dump',
            'generate' => 'generate-dump',
            'delete' => 'delete-dump',
        ],
    ],
    'zip' => [
        'file_ending' => '.zip',
        'generate' => [
            'type' => 'script',
            'script' => '/usr/bin/zip',
            'options' => [
                '-r',
                "${wgDataDumpDirectory}" . '${filename}',
                "$IP/images/"
            ],
        ],
        'limit' => 1,
        'permissions' => [
            'view' => 'view-dump',
            'generate' => 'generate-dump',
            'delete' => 'delete-dump',
        ],
    ],
];

Note that ${filename} is replaced internally in the extension so make sure that it is always in a single string not in a double string.

The limit parameter specifies how many dumps can be generated for that wiki.

Troubleshooting

If you're experiencing issues with failed data dumps, you can look at your Job Queue 's log file. You can search for DataDumpGenerateJob to find an area where the Job Queue is running your dump.

PHP binary location

If your log file contains something similar: [exec] Possibly missing executable file: '/usr/bin/php', then you might need to set $wgPhpCli to a correct value for your environment. You can use whereis php to double check.

Zip Tooling

If your log file contains something similar to: [exec] Possibly missing executable file: '/usr/bin/zip' then you need to ensure the appropriate zip tooling for your job is installed on your Host machine.
