Manual:Logging table
| ↑ Manual:Contents | MediaWiki database layout | logging table |
| MediaWiki version: | ≥ 1.4 |
Every log action in MediaWiki is logged in the logging table. Users can see those edits on Special:Log, except for a few restricted logs (like Special:Log/suppress).
The contents of this table is what you see on the Special:Log page. For example:
14:18, 25 June 2008 Jacksprat (Talk | contribs| block) uploaded "Image:Climb.jpg" (Added this image for the climbing page)
Fields
log_id
| MediaWiki version: | ≥ 1.10 |
Primary key for the table. rc_logid is a foreign key linking to this column.
log_type
The type of the log action, or the "log type".
You can filter by some values of this type on Special:Log.
Comparable to rc_log_type.
Example values from some Wikimedia wikis are as follows (including now-obsolete logs and several extensions):
- 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
The action performed. There may be multiple actions possible for a given type: for example, an entry with the type delete may have the action delete or restore, etc. Comparable to rc_log_action. See also API:Logevents. See Manual:Log actions.
log_timestamp
The time the action was performed, in the timestamp format MediaWiki uses everywhere in the database: yyyymmddhhmmss ("14:18, 25 June 2008" in example). Has the same value as the corresponding recentchanges.rc_timestamp and revision.rev_timestamp. Does not necessarily have the same value as the corresponding image.img_timestamp, in the case of file uploads.
log_user
| MediaWiki version: | ≤ 1.33 |
The id of the user who performed the action. This is a reference into the user table (the user id of "Jacksprat" in example). Comparable to rc_user and rev_user.
Deprecated in favor of log_actor.
log_user_text
| MediaWiki version: | ≥ 1.16 |
user_name of the user who performed the action, intended primarily for anonymous users, fillable by maintenance/populateLogUsertext.php. Comparable to rc_user_text and rev_user_text.
Deprecated in favor of log_actor.
log_actor
| MediaWiki version: | ≥ 1.31 Gerrit change 380669 |
This is a foreign key to actor_id in the actor 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 page table ("Image:Climb.jpg" in example). Comparable to rc_namespace.
logging table may contain rows with log_namespace < 0:- 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 title of the affected page. Together with log_namespace, this is a reference into the page table. Comparable to rc_title
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
| MediaWiki version: | ≥ 1.16 |
The page_id that this log action is about. Comparable to rc_cur_id and rev_page. In the case of a page move, this is set to the page_id of the moved page (since Gerrit change 157872). Formerly, it was the page_id of the redirect, or 0 if the page was moved without creating a redirect.
log_comment
| MediaWiki version: | ≤ 1.32 |
The comment given for the action; that is the upload comment for uploads, the deletion comment for deletions, etc. Comparable to rc_comment and rev_comment.
(deprecated); log_comment_id and the comment table should be used instead!
log_comment_id
| MediaWiki version: | ≥ 1.30 |
This is a foreign key to comment_id in the comment table.
log_params
| MediaWiki version: | ≥ 1.5 |
Additional parameters, usually empty. Mirrored in rc_params. 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 noredir.
For other examples, see Manual:Log parameters.
| MediaWiki version: | ≥ 1.19 |
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%'
| MediaWiki version: | ≥ 1.21 |
Since 1.21, 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 log_search to facilitate indexed queries. Log parameters are typically set using functions such as ManualLogEntry::setParameters() and LogPage::addEntry().
log_deleted
| MediaWiki version: | ≥ 1.10 |
Used with the RevisionDelete system to delete log entries. Comparable to rc_deleted and rev_deleted. 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.
