Manual:Logging table/zh

MediaWiki中每个日志操作都记录在logging表中. 用户可以在Special:Log上看到这些编辑，但少数受限日志（如Special:Log/suppress）除外.

此表的内容是您在Special:Log页面上看到的东西. 例如：



log_id
该表的主键. 是链接到此列的外键.

log_type
日志操作的类型，即“日志类型”.

您可以在Special:Log上按此类型的某些值进行过滤.

和对应.

来自一些维基媒体wiki的示例值如下（包括现在过时的日志和几个扩展）：


 * abusefilter
 * block
 * close
 * contentmodel
 * delete
 * gblblock
 * gblrights
 * globalauth
 * gwtoolset
 * import
 * liquidthreads
 * lock
 * managetags
 * massmessage
 * merge
 * move
 * mwoauthconsumer
 * newsletter
 * newusers
 * notifytranslators
 * pagelang
 * pagetranslation
 * patrol
 * protect
 * renameuser
 * review
 * rights
 * spamblacklist
 * tag
 * thanks
 * timedmediahandler
 * translationreview
 * upload
 * usermerge

log_action
已经完成的操作. 对于给定类型，可能存在多种可能的操作：例如，具有“删除”类型的字段可以具有操作“删除”或“恢复”等. 和对应. 参见. 参见.

log_timestamp
执行操作的时间，时间戳格式，允许MediaWiki在数据库中的任何位置使用：yyyymmddhhmmss（“比如2008年6月25日 14:18”）. 与和对应. 如果日志事件是文件上传，则此字段不一定与$recordUpload生成的相同.

log_user
The of the user who performed the action. This is a reference into the table (the user id of "Jacksprat" in example). Comparable to and.

Deprecated in favor of log_actor.

log_user_text
of the user who performed the action, intended primarily for anonymous users, fillable by maintenance/populateLogUsertext.php. Comparable to and.

Deprecated in favor of log_actor.

log_actor
This is a foreign key to in the  table, corresponding to the user (registered or anonymous) who performed the action.

log_namespace
The namespace of the affected page. Together with log_title, this is a reference into the table ("Image:Climb.jpg" in example). Comparable to.


 * Special:Renameuser with log_type and log_action being either "" or "renameuser"
 * Special:Userlogin with log_type being "newusers" and log_action e.g. being "create"

log_title
The of the affected page. Together with log_namespace, this is a reference into the table. Comparable to

The title is also known as the log entry's 'target'.

For user blocks, this is the blocked user's username. For thanks action, this is the thanked user's username.

log_page
The that this log action is about. Comparable to and. In the case of a page move, this is set to the page_id of the moved page (since ). Formerly, it was the page_id of the redirect, or 0 if the page was moved without creating a redirect.

log_comment
The comment given for the action; that is the upload comment for uploads, the deletion comment for deletions, etc. Comparable to and.


 * log_comment_id and the table should be used instead!

log_comment_id
This is a foreign key to in the  table.

log_params
Additional parameters, usually empty. Mirrored in. log_params is usually serialized, but not always; sometimes, for historical reasons, fields for log_params are separated by a newline. Anyone creating a new log type should use the PHP serialization.

For user blocks, log_params contains the duration of the block and other data, in human readable form, e.g. "2 weeks nocreate,noautoblock,noemail". For page moves, it contains a serialized array of the prefixed page title the page was moved to (i.e. in FULLPAGENAME format) and the boolean value of. For other examples, see.

Since 1.19, data in log_params is in a different format. For instance, if you want to filter patrol/patrol log entries excluding autopatrol, pre-1.19 log entries need: log.log_params LIKE '%\n0' while entries added in 1.19 and further need (serialized PHP arrays): log.log_params LIKE '%"6::auto";i:0%'

Since, log_params is always serialized for newusers log too. An entry now looks like:

mysql> select log_params, log_action from logging where log_user = 4681690; +--++ +--++ +--++
 * log_params                      | log_action |
 * a:1:{s:9:"4::userid";i:4681690;} | autocreate |

while it used to look like:

mysql> select log_params, log_action from logging where log_user = 2298743; +++ +++ +++
 * log_params | log_action |
 * 2298743   | autocreate |

The numbers, e.g. the 4 in "4::userid", are used as the argument number for message keys (e.g. $1, $2,...). The numbering should start with number 4, as the first three parameters are hardcoded for every message. If there is no message key, then a number should not be used. Some data contained in log_params are also contained in to facilitate indexed queries. Log parameters are typically set using functions such as and.

log_deleted
Used with the system to delete log entries. Comparable to and. It is a bit field. Take the sum of the following to determine what it represents:


 * 1 Action deleted
 * 2 Comment deleted
 * 4 User deleted
 * 8 If the deleted information is restricted. If this field is not set, then only deletedhistory right is needed, otherwise you need suppressrevision right. (On Wikimedia wikis, this corresponds to if admins can view the entry, or if only oversighters can)

For example, if the value is 6 (4+2), then the action would be visible, but the comment and user would not be unless you had deletedhistory rights.
